By contrast, -the GNU General Public License is intended to guarantee your freedom to -share and change all versions of a program--to make sure it remains free -software for all its users. We, the Free Software Foundation, use the -GNU General Public License for most of our software; it applies also to -any other work released this way by its authors. You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -them if you wish), that you receive source code or can get it if you -want it, that you can change the software or use pieces of it in new -free programs, and that you know you can do these things. - - To protect your rights, we need to prevent others from denying you -these rights or asking you to surrender the rights. Therefore, you have -certain responsibilities if you distribute copies of the software, or if -you modify it: responsibilities to respect the freedom of others. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must pass on to the recipients the same -freedoms that you received. You must make sure that they, too, receive -or can get the source code. And you must show them these terms so they -know their rights. - - Developers that use the GNU GPL protect your rights with two steps: -(1) assert copyright on the software, and (2) offer you this License -giving you legal permission to copy, distribute and/or modify it. - - For the developers' and authors' protection, the GPL clearly explains -that there is no warranty for this free software. For both users' and -authors' sake, the GPL requires that modified versions be marked as -changed, so that their problems will not be attributed erroneously to -authors of previous versions. - - Some devices are designed to deny users access to install or run -modified versions of the software inside them, although the manufacturer -can do so. This is fundamentally incompatible with the aim of -protecting users' freedom to change the software. The systematic -pattern of such abuse occurs in the area of products for individuals to -use, which is precisely where it is most unacceptable. Therefore, we -have designed this version of the GPL to prohibit the practice for those -products. If such problems arise substantially in other domains, we -stand ready to extend this provision to those domains in future versions -of the GPL, as needed to protect the freedom of users. - - Finally, every program is threatened constantly by software patents. -States should not allow patents to restrict development and use of -software on general-purpose computers, but in those that do, we wish to -avoid the special danger that patents applied to a free program could -make it effectively proprietary. To prevent this, the GPL assures that -patents cannot be used to render the program non-free. - - The precise terms and conditions for copying, distribution and -modification follow. - - TERMS AND CONDITIONS - - 0. Definitions. - - "This License" refers to version 3 of the GNU General Public License. - - "Copyright" also means copyright-like laws that apply to other kinds of -works, such as semiconductor masks. - - "The Program" refers to any copyrightable work licensed under this -License. Each licensee is addressed as "you". "Licensees" and -"recipients" may be individuals or organizations. - - To "modify" a work means to copy from or adapt all or part of the work -in a fashion requiring copyright permission, other than the making of an -exact copy. The resulting work is called a "modified version" of the -earlier work or a work "based on" the earlier work. - - A "covered work" means either the unmodified Program or a work based -on the Program. - - To "propagate" a work means to do anything with it that, without -permission, would make you directly or secondarily liable for -infringement under applicable copyright law, except executing it on a -computer or modifying a private copy. Propagation includes copying, -distribution (with or without modification), making available to the -public, and in some countries other activities as well. - - To "convey" a work means any kind of propagation that enables other -parties to make or receive copies. Mere interaction with a user through -a computer network, with no transfer of a copy, is not conveying. - - An interactive user interface displays "Appropriate Legal Notices" -to the extent that it includes a convenient and prominently visible -feature that (1) displays an appropriate copyright notice, and (2) -tells the user that there is no warranty for the work (except to the -extent that warranties are provided), that licensees may convey the -work under this License, and how to view a copy of this License. If -the interface presents a list of user commands or options, such as a -menu, a prominent item in the list meets this criterion. - - 1. Source Code. - - The "source code" for a work means the preferred form of the work -for making modifications to it. "Object code" means any non-source -form of a work. - - A "Standard Interface" means an interface that either is an official -standard defined by a recognized standards body, or, in the case of -interfaces specified for a particular programming language, one that -is widely used among developers working in that language. - - The "System Libraries" of an executable work include anything, other -than the work as a whole, that (a) is included in the normal form of -packaging a Major Component, but which is not part of that Major -Component, and (b) serves only to enable use of the work with that -Major Component, or to implement a Standard Interface for which an -implementation is available to the public in source code form. A -"Major Component", in this context, means a major essential component -(kernel, window system, and so on) of the specific operating system -(if any) on which the executable work runs, or a compiler used to -produce the work, or an object code interpreter used to run it. - - The "Corresponding Source" for a work in object code form means all -the source code needed to generate, install, and (for an executable -work) run the object code and to modify the work, including scripts to -control those activities. However, it does not include the work's -System Libraries, or general-purpose tools or generally available free -programs which are used unmodified in performing those activities but -which are not part of the work. For example, Corresponding Source -includes interface definition files associated with source files for -the work, and the source code for shared libraries and dynamically -linked subprograms that the work is specifically designed to require, -such as by intimate data communication or control flow between those -subprograms and other parts of the work. - - The Corresponding Source need not include anything that users -can regenerate automatically from other parts of the Corresponding -Source. - - The Corresponding Source for a work in source code form is that -same work. - - 2. Basic Permissions. - - All rights granted under this License are granted for the term of -copyright on the Program, and are irrevocable provided the stated -conditions are met. This License explicitly affirms your unlimited -permission to run the unmodified Program. The output from running a -covered work is covered by this License only if the output, given its -content, constitutes a covered work. This License acknowledges your -rights of fair use or other equivalent, as provided by copyright law. - - You may make, run and propagate covered works that you do not -convey, without conditions so long as your license otherwise remains -in force. You may convey covered works to others for the sole purpose -of having them make modifications exclusively for you, or provide you -with facilities for running those works, provided that you comply with -the terms of this License in conveying all material for which you do -not control copyright. Those thus making or running the covered works -for you must do so exclusively on your behalf, under your direction -and control, on terms that prohibit them from making any copies of -your copyrighted material outside their relationship with you. - - Conveying under any other circumstances is permitted solely under -the conditions stated below. Sublicensing is not allowed; section 10 -makes it unnecessary. - - 3. Protecting Users' Legal Rights From Anti-Circumvention Law. - - No covered work shall be deemed part of an effective technological -measure under any applicable law fulfilling obligations under article -11 of the WIPO copyright treaty adopted on 20 December 1996, or -similar laws prohibiting or restricting circumvention of such -measures. - - When you convey a covered work, you waive any legal power to forbid -circumvention of technological measures to the extent such circumvention -is effected by exercising rights under this License with respect to -the covered work, and you disclaim any intention to limit operation or -modification of the work as a means of enforcing, against the work's -users, your or third parties' legal rights to forbid circumvention of -technological measures. - - 4. Conveying Verbatim Copies. - - You may convey verbatim copies of the Program's source code as you -receive it, in any medium, provided that you conspicuously and -appropriately publish on each copy an appropriate copyright notice; -keep intact all notices stating that this License and any -non-permissive terms added in accord with section 7 apply to the code; -keep intact all notices of the absence of any warranty; and give all -recipients a copy of this License along with the Program. - - You may charge any price or no price for each copy that you convey, -and you may offer support or warranty protection for a fee. - - 5. Conveying Modified Source Versions. - - You may convey a work based on the Program, or the modifications to -produce it from the Program, in the form of source code under the -terms of section 4, provided that you also meet all of these conditions: - - a) The work must carry prominent notices stating that you modified - it, and giving a relevant date. - - b) The work must carry prominent notices stating that it is - released under this License and any conditions added under section - 7. This requirement modifies the requirement in section 4 to - "keep intact all notices". - - c) You must license the entire work, as a whole, under this - License to anyone who comes into possession of a copy. This - License will therefore apply, along with any applicable section 7 - additional terms, to the whole of the work, and all its parts, - regardless of how they are packaged. This License gives no - permission to license the work in any other way, but it does not - invalidate such permission if you have separately received it. - - d) If the work has interactive user interfaces, each must display - Appropriate Legal Notices; however, if the Program has interactive - interfaces that do not display Appropriate Legal Notices, your - work need not make them do so. - - A compilation of a covered work with other separate and independent -works, which are not by their nature extensions of the covered work, -and which are not combined with it such as to form a larger program, -in or on a volume of a storage or distribution medium, is called an -"aggregate" if the compilation and its resulting copyright are not -used to limit the access or legal rights of the compilation's users -beyond what the individual works permit. Inclusion of a covered work -in an aggregate does not cause this License to apply to the other -parts of the aggregate. - - 6. Conveying Non-Source Forms. - - You may convey a covered work in object code form under the terms -of sections 4 and 5, provided that you also convey the -machine-readable Corresponding Source under the terms of this License, -in one of these ways: - - a) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by the - Corresponding Source fixed on a durable physical medium - customarily used for software interchange. - - b) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by a - written offer, valid for at least three years and valid for as - long as you offer spare parts or customer support for that product - model, to give anyone who possesses the object code either (1) a - copy of the Corresponding Source for all the software in the - product that is covered by this License, on a durable physical - medium customarily used for software interchange, for a price no - more than your reasonable cost of physically performing this - conveying of source, or (2) access to copy the - Corresponding Source from a network server at no charge. - - c) Convey individual copies of the object code with a copy of the - written offer to provide the Corresponding Source. This - alternative is allowed only occasionally and noncommercially, and - only if you received the object code with such an offer, in accord - with subsection 6b. - - d) Convey the object code by offering access from a designated - place (gratis or for a charge), and offer equivalent access to the - Corresponding Source in the same way through the same place at no - further charge. You need not require recipients to copy the - Corresponding Source along with the object code. If the place to - copy the object code is a network server, the Corresponding Source - may be on a different server (operated by you or a third party) - that supports equivalent copying facilities, provided you maintain - clear directions next to the object code saying where to find the - Corresponding Source. Regardless of what server hosts the - Corresponding Source, you remain obligated to ensure that it is - available for as long as needed to satisfy these requirements. - - e) Convey the object code using peer-to-peer transmission, provided - you inform other peers where the object code and Corresponding - Source of the work are being offered to the general public at no - charge under subsection 6d. - - A separable portion of the object code, whose source code is excluded -from the Corresponding Source as a System Library, need not be -included in conveying the object code work. - - A "User Product" is either (1) a "consumer product", which means any -tangible personal property which is normally used for personal, family, -or household purposes, or (2) anything designed or sold for incorporation -into a dwelling. In determining whether a product is a consumer product, -doubtful cases shall be resolved in favor of coverage. For a particular -product received by a particular user, "normally used" refers to a -typical or common use of that class of product, regardless of the status -of the particular user or of the way in which the particular user -actually uses, or expects or is expected to use, the product. A product -is a consumer product regardless of whether the product has substantial -commercial, industrial or non-consumer uses, unless such uses represent -the only significant mode of use of the product. - - "Installation Information" for a User Product means any methods, -procedures, authorization keys, or other information required to install -and execute modified versions of a covered work in that User Product from -a modified version of its Corresponding Source. The information must -suffice to ensure that the continued functioning of the modified object -code is in no case prevented or interfered with solely because -modification has been made. - - If you convey an object code work under this section in, or with, or -specifically for use in, a User Product, and the conveying occurs as -part of a transaction in which the right of possession and use of the -User Product is transferred to the recipient in perpetuity or for a -fixed term (regardless of how the transaction is characterized), the -Corresponding Source conveyed under this section must be accompanied -by the Installation Information. But this requirement does not apply -if neither you nor any third party retains the ability to install -modified object code on the User Product (for example, the work has -been installed in ROM). - - The requirement to provide Installation Information does not include a -requirement to continue to provide support service, warranty, or updates -for a work that has been modified or installed by the recipient, or for -the User Product in which it has been modified or installed. Access to a -network may be denied when the modification itself materially and -adversely affects the operation of the network or violates the rules and -protocols for communication across the network. - - Corresponding Source conveyed, and Installation Information provided, -in accord with this section must be in a format that is publicly -documented (and with an implementation available to the public in -source code form), and must require no special password or key for -unpacking, reading or copying. - - 7. Additional Terms. - - "Additional permissions" are terms that supplement the terms of this -License by making exceptions from one or more of its conditions. -Additional permissions that are applicable to the entire Program shall -be treated as though they were included in this License, to the extent -that they are valid under applicable law. If additional permissions -apply only to part of the Program, that part may be used separately -under those permissions, but the entire Program remains governed by -this License without regard to the additional permissions. - - When you convey a copy of a covered work, you may at your option -remove any additional permissions from that copy, or from any part of -it. (Additional permissions may be written to require their own -removal in certain cases when you modify the work.) You may place -additional permissions on material, added by you to a covered work, -for which you have or can give appropriate copyright permission. - - Notwithstanding any other provision of this License, for material you -add to a covered work, you may (if authorized by the copyright holders of -that material) supplement the terms of this License with terms: - - a) Disclaiming warranty or limiting liability differently from the - terms of sections 15 and 16 of this License; or - - b) Requiring preservation of specified reasonable legal notices or - author attributions in that material or in the Appropriate Legal - Notices displayed by works containing it; or - - c) Prohibiting misrepresentation of the origin of that material, or - requiring that modified versions of such material be marked in - reasonable ways as different from the original version; or - - d) Limiting the use for publicity purposes of names of licensors or - authors of the material; or - - e) Declining to grant rights under trademark law for use of some - trade names, trademarks, or service marks; or - - f) Requiring indemnification of licensors and authors of that - material by anyone who conveys the material (or modified versions of - it) with contractual assumptions of liability to the recipient, for - any liability that these contractual assumptions directly impose on - those licensors and authors. - - All other non-permissive additional terms are considered "further -restrictions" within the meaning of section 10. If the Program as you -received it, or any part of it, contains a notice stating that it is -governed by this License along with a term that is a further -restriction, you may remove that term. If a license document contains -a further restriction but permits relicensing or conveying under this -License, you may add to a covered work material governed by the terms -of that license document, provided that the further restriction does -not survive such relicensing or conveying. - - If you add terms to a covered work in accord with this section, you -must place, in the relevant source files, a statement of the -additional terms that apply to those files, or a notice indicating -where to find the applicable terms. - - Additional terms, permissive or non-permissive, may be stated in the -form of a separately written license, or stated as exceptions; -the above requirements apply either way. - - 8. Termination. - - You may not propagate or modify a covered work except as expressly -provided under this License. Any attempt otherwise to propagate or -modify it is void, and will automatically terminate your rights under -this License (including any patent licenses granted under the third -paragraph of section 11). - - However, if you cease all violation of this License, then your -license from a particular copyright holder is reinstated (a) -provisionally, unless and until the copyright holder explicitly and -finally terminates your license, and (b) permanently, if the copyright -holder fails to notify you of the violation by some reasonable means -prior to 60 days after the cessation. - - Moreover, your license from a particular copyright holder is -reinstated permanently if the copyright holder notifies you of the -violation by some reasonable means, this is the first time you have -received notice of violation of this License (for any work) from that -copyright holder, and you cure the violation prior to 30 days after -your receipt of the notice. - - Termination of your rights under this section does not terminate the -licenses of parties who have received copies or rights from you under -this License. If your rights have been terminated and not permanently -reinstated, you do not qualify to receive new licenses for the same -material under section 10. - - 9. Acceptance Not Required for Having Copies. - - You are not required to accept this License in order to receive or -run a copy of the Program. Ancillary propagation of a covered work -occurring solely as a consequence of using peer-to-peer transmission -to receive a copy likewise does not require acceptance. However, -nothing other than this License grants you permission to propagate or -modify any covered work. These actions infringe copyright if you do -not accept this License. Therefore, by modifying or propagating a -covered work, you indicate your acceptance of this License to do so. - - 10. Automatic Licensing of Downstream Recipients. - - Each time you convey a covered work, the recipient automatically -receives a license from the original licensors, to run, modify and -propagate that work, subject to this License. You are not responsible -for enforcing compliance by third parties with this License. - - An "entity transaction" is a transaction transferring control of an -organization, or substantially all assets of one, or subdividing an -organization, or merging organizations. If propagation of a covered -work results from an entity transaction, each party to that -transaction who receives a copy of the work also receives whatever -licenses to the work the party's predecessor in interest had or could -give under the previous paragraph, plus a right to possession of the -Corresponding Source of the work from the predecessor in interest, if -the predecessor has it or can get it with reasonable efforts. - - You may not impose any further restrictions on the exercise of the -rights granted or affirmed under this License. For example, you may -not impose a license fee, royalty, or other charge for exercise of -rights granted under this License, and you may not initiate litigation -(including a cross-claim or counterclaim in a lawsuit) alleging that -any patent claim is infringed by making, using, selling, offering for -sale, or importing the Program or any portion of it. - - 11. Patents. - - A "contributor" is a copyright holder who authorizes use under this -License of the Program or a work on which the Program is based. The -work thus licensed is called the contributor's "contributor version". - - A contributor's "essential patent claims" are all patent claims -owned or controlled by the contributor, whether already acquired or -hereafter acquired, that would be infringed by some manner, permitted -by this License, of making, using, or selling its contributor version, -but do not include claims that would be infringed only as a -consequence of further modification of the contributor version. For -purposes of this definition, "control" includes the right to grant -patent sublicenses in a manner consistent with the requirements of -this License. - - Each contributor grants you a non-exclusive, worldwide, royalty-free -patent license under the contributor's essential patent claims, to -make, use, sell, offer for sale, import and otherwise run, modify and -propagate the contents of its contributor version. - - In the following three paragraphs, a "patent license" is any express -agreement or commitment, however denominated, not to enforce a patent -(such as an express permission to practice a patent or covenant not to -sue for patent infringement). To "grant" such a patent license to a -party means to make such an agreement or commitment not to enforce a -patent against the party. - - If you convey a covered work, knowingly relying on a patent license, -and the Corresponding Source of the work is not available for anyone -to copy, free of charge and under the terms of this License, through a -publicly available network server or other readily accessible means, -then you must either (1) cause the Corresponding Source to be so -available, or (2) arrange to deprive yourself of the benefit of the -patent license for this particular work, or (3) arrange, in a manner -consistent with the requirements of this License, to extend the patent -license to downstream recipients. "Knowingly relying" means you have -actual knowledge that, but for the patent license, your conveying the -covered work in a country, or your recipient's use of the covered work -in a country, would infringe one or more identifiable patents in that -country that you have reason to believe are valid. - - If, pursuant to or in connection with a single transaction or -arrangement, you convey, or propagate by procuring conveyance of, a -covered work, and grant a patent license to some of the parties -receiving the covered work authorizing them to use, propagate, modify -or convey a specific copy of the covered work, then the patent license -you grant is automatically extended to all recipients of the covered -work and works based on it. - - A patent license is "discriminatory" if it does not include within -the scope of its coverage, prohibits the exercise of, or is -conditioned on the non-exercise of one or more of the rights that are -specifically granted under this License. You may not convey a covered -work if you are a party to an arrangement with a third party that is -in the business of distributing software, under which you make payment -to the third party based on the extent of your activity of conveying -the work, and under which the third party grants, to any of the -parties who would receive the covered work from you, a discriminatory -patent license (a) in connection with copies of the covered work -conveyed by you (or copies made from those copies), or (b) primarily -for and in connection with specific products or compilations that -contain the covered work, unless you entered into that arrangement, -or that patent license was granted, prior to 28 March 2007. - - Nothing in this License shall be construed as excluding or limiting -any implied license or other defenses to infringement that may -otherwise be available to you under applicable patent law. - - 12. No Surrender of Others' Freedom. - - If conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot convey a -covered work so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you may -not convey it at all. For example, if you agree to terms that obligate you -to collect a royalty for further conveying from those to whom you convey -the Program, the only way you could satisfy both those terms and this -License would be to refrain entirely from conveying the Program. - - 13. Use with the GNU Affero General Public License. - - Notwithstanding any other provision of this License, you have -permission to link or combine any covered work with a work licensed -under version 3 of the GNU Affero General Public License into a single -combined work, and to convey the resulting work. The terms of this -License will continue to apply to the part which is the covered work, -but the special requirements of the GNU Affero General Public License, -section 13, concerning interaction through a network will apply to the -combination as such. - - 14. Revised Versions of this License. - - The Free Software Foundation may publish revised and/or new versions of -the GNU General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - - Each version is given a distinguishing version number. If the -Program specifies that a certain numbered version of the GNU General -Public License "or any later version" applies to it, you have the -option of following the terms and conditions either of that numbered -version or of any later version published by the Free Software -Foundation. If the Program does not specify a version number of the -GNU General Public License, you may choose any version ever published -by the Free Software Foundation. - - If the Program specifies that a proxy can decide which future -versions of the GNU General Public License can be used, that proxy's -public statement of acceptance of a version permanently authorizes you -to choose that version for the Program. - - Later license versions may give you additional or different -permissions. However, no additional obligations are imposed on any -author or copyright holder as a result of your choosing to follow a -later version. - - 15. Disclaimer of Warranty. - - THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY -APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT -HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY -OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, -THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM -IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF -ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. Limitation of Liability. - - IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS -THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY -GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE -USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF -DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD -PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), -EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF -SUCH DAMAGES. - - 17. Interpretation of Sections 15 and 16. - - If the disclaimer of warranty and limitation of liability provided -above cannot be given local legal effect according to their terms, -reviewing courts shall apply local law that most closely approximates -an absolute waiver of all civil liability in connection with the -Program, unless a warranty or assumption of liability accompanies a -copy of the Program in return for a fee. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -state the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software: you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation, either version 3 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program. If not, see . - -Also add information on how to contact you by electronic and paper mail. - - If the program does terminal interaction, make it output a short -notice like this when it starts in an interactive mode: - - Copyright (C) - This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, your program's commands -might be different; for a GUI interface, you would use an "about box". - - You should also get your employer (if you work as a programmer) or school, -if any, to sign a "copyright disclaimer" for the program, if necessary. -For more information on this, and how to apply and follow the GNU GPL, see -. - - The GNU General Public License does not permit incorporating your program -into proprietary programs. If your program is a subroutine library, you -may consider it more useful to permit linking proprietary applications with -the library. If this is what you want to do, use the GNU Lesser General -Public License instead of this License.

This file is offered as-is, -without warranty of any kind. - -Basic Installation -================== - - Briefly, the shell command `./configure && make && make install' -should configure, build, and install this package. The following -more-detailed instructions are generic; see the `README' file for -instructions specific to this package. Some packages provide this -`INSTALL' file but do not implement all of the features documented -below. The lack of an optional feature in a given package is not -necessarily a bug. More recommendations for GNU packages can be found -in *note Makefile Conventions: (standards)Makefile Conventions. - - The `configure' shell script attempts to guess correct values for -various system-dependent variables used during compilation. It uses -those values to create a `Makefile' in each directory of the package. -It may also create one or more `.h' files containing system-dependent -definitions. Finally, it creates a shell script `config.status' that -you can run in the future to recreate the current configuration, and a -file `config.log' containing compiler output (useful mainly for -debugging `configure'). - - It can also use an optional file (typically called `config.cache' -and enabled with `--cache-file=config.cache' or simply `-C') that saves -the results of its tests to speed up reconfiguring. Caching is -disabled by default to prevent problems with accidental use of stale -cache files. - - If you need to do unusual things to compile the package, please try -to figure out how `configure' could check whether to do them, and mail -diffs or instructions to the address given in the `README' so they can -be considered for the next release. If you are using the cache, and at -some point `config.cache' contains results you don't want to keep, you -may remove or edit it. - - The file `configure.ac' (or `configure.in') is used to create -`configure' by a program called `autoconf'. You need `configure.ac' if -you want to change it or regenerate `configure' using a newer version -of `autoconf'. - - The simplest way to compile this package is: - - 1. `cd' to the directory containing the package's source code and type - `./configure' to configure the package for your system. - - Running `configure' might take a while. While running, it prints - some messages telling which features it is checking for. - - 2. Type `make' to compile the package. - - 3. Optionally, type `make check' to run any self-tests that come with - the package, generally using the just-built uninstalled binaries. - - 4. Type `make install' to install the programs and any data files and - documentation. When installing into a prefix owned by root, it is - recommended that the package be configured and built as a regular - user, and only the `make install' phase executed with root - privileges. - - 5. Optionally, type `make installcheck' to repeat any self-tests, but - this time using the binaries in their final installed location. - This target does not install anything. Running this target as a - regular user, particularly if the prior `make install' required - root privileges, verifies that the installation completed - correctly. - - 6. You can remove the program binaries and object files from the - source code directory by typing `make clean'. To also remove the - files that `configure' created (so you can compile the package for - a different kind of computer), type `make distclean'. There is - also a `make maintainer-clean' target, but that is intended mainly - for the package's developers. If you use it, you may have to get - all sorts of other programs in order to regenerate files that came - with the distribution. - - 7. Often, you can also type `make uninstall' to remove the installed - files again. In practice, not all packages have tested that - uninstallation works correctly, even though it is required by the - GNU Coding Standards. - - 8. Some packages, particularly those that use Automake, provide `make - distcheck', which can by used by developers to test that all other - targets like `make install' and `make uninstall' work correctly. - This target is generally not run by end users. - -Compilers and Options -===================== - - Some systems require unusual options for compilation or linking that -the `configure' script does not know about. Run `./configure --help' -for details on some of the pertinent environment variables. - - You can give `configure' initial values for configuration parameters -by setting variables in the command line or in the environment. Here -is an example: - - ./configure CC=c99 CFLAGS=-g LIBS=-lposix - - *Note Defining Variables::, for more details. - -Compiling For Multiple Architectures -==================================== - - You can compile the package for more than one kind of computer at the -same time, by placing the object files for each architecture in their -own directory. To do this, you can use GNU `make'. `cd' to the -directory where you want the object files and executables to go and run -the `configure' script. `configure' automatically checks for the -source code in the directory that `configure' is in and in `..'. This -is known as a "VPATH" build. - - With a non-GNU `make', it is safer to compile the package for one -architecture at a time in the source code directory. After you have -installed the package for one architecture, use `make distclean' before -reconfiguring for another architecture. - - On MacOS X 10.5 and later systems, you can create libraries and -executables that work on multiple system types--known as "fat" or -"universal" binaries--by specifying multiple `-arch' options to the -compiler but only a single `-arch' option to the preprocessor. Like -this: - - ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ - CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ - CPP="gcc -E" CXXCPP="g++ -E" - - This is not guaranteed to produce working output in all cases, you -may have to build one architecture at a time and combine the results -using the `lipo' tool if you have problems. - -Installation Names -================== - - By default, `make install' installs the package's commands under -`/usr/local/bin', include files under `/usr/local/include', etc. You -can specify an installation prefix other than `/usr/local' by giving -`configure' the option `--prefix=PREFIX', where PREFIX must be an -absolute file name. - - You can specify separate installation prefixes for -architecture-specific files and architecture-independent files. If you -pass the option `--exec-prefix=PREFIX' to `configure', the package uses -PREFIX as the prefix for installing programs and libraries. -Documentation and other data files still use the regular prefix. - - In addition, if you use an unusual directory layout you can give -options like `--bindir=DIR' to specify different values for particular -kinds of files. Run `configure --help' for a list of the directories -you can set and what kinds of files go in them. In general, the -default for these options is expressed in terms of `${prefix}', so that -specifying just `--prefix' will affect all of the other directory -specifications that were not explicitly provided. - - The most portable way to affect installation locations is to pass the -correct locations to `configure'; however, many packages provide one or -both of the following shortcuts of passing variable assignments to the -`make install' command line to change installation locations without -having to reconfigure or recompile. - - The first method involves providing an override variable for each -affected directory. For example, `make install -prefix=/alternate/directory' will choose an alternate location for all -directory configuration variables that were expressed in terms of -`${prefix}'. Any directories that were specified during `configure', -but not in terms of `${prefix}', must each be overridden at install -time for the entire installation to be relocated. The approach of -makefile variable overrides for each directory variable is required by -the GNU Coding Standards, and ideally causes no recompilation. -However, some platforms have known limitations with the semantics of -shared libraries that end up requiring recompilation when using this -method, particularly noticeable in packages that use GNU Libtool. - - The second method involves providing the `DESTDIR' variable. For -example, `make install DESTDIR=/alternate/directory' will prepend -`/alternate/directory' before all installation names. The approach of -`DESTDIR' overrides is not required by the GNU Coding Standards, and -does not work on platforms that have drive letters. On the other hand, -it does better at avoiding recompilation issues, and works well even -when some directory options were not specified in terms of `${prefix}' -at `configure' time. - -Optional Features -================= - - If the package supports it, you can cause programs to be installed -with an extra prefix or suffix on their names by giving `configure' the -option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. - - Some packages pay attention to `--enable-FEATURE' options to -`configure', where FEATURE indicates an optional part of the package. -They may also pay attention to `--with-PACKAGE' options, where PACKAGE -is something like `gnu-as' or `x' (for the X Window System). The -`README' should mention any `--enable-' and `--with-' options that the -package recognizes. - - For packages that use the X Window System, `configure' can usually -find the X include and library files automatically, but if it doesn't, -you can use the `configure' options `--x-includes=DIR' and -`--x-libraries=DIR' to specify their locations. - - Some packages offer the ability to configure how verbose the -execution of `make' will be. For these packages, running `./configure ---enable-silent-rules' sets the default to minimal output, which can be -overridden with `make V=1'; while running `./configure ---disable-silent-rules' sets the default to verbose, which can be -overridden with `make V=0'. - -Particular systems -================== - - On HP-UX, the default C compiler is not ANSI C compatible. If GNU -CC is not installed, it is recommended to use the following options in -order to use an ANSI C compiler: - - ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" - -and if that doesn't work, install pre-built binaries of GCC for HP-UX. - - HP-UX `make' updates targets which have the same time stamps as -their prerequisites, which makes it generally unusable when shipped -generated files such as `configure' are involved. Use GNU `make' -instead. - - On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot -parse its `' header file. The option `-nodtk' can be used as -a workaround. If GNU CC is not installed, it is therefore recommended -to try - - ./configure CC="cc" - -and if that doesn't work, try - - ./configure CC="cc -nodtk" - - On Solaris, don't put `/usr/ucb' early in your `PATH'. This -directory contains several dysfunctional programs; working variants of -these programs are available in `/usr/bin'. So, if you need `/usr/ucb' -in your `PATH', put it _after_ `/usr/bin'. - - On Haiku, software installed for all users goes in `/boot/common', -not `/usr/local'. It is recommended to use the following options: - - ./configure --prefix=/boot/common - -Specifying the System Type -========================== - - There may be some features `configure' cannot figure out -automatically, but needs to determine by the type of machine the package -will run on. Usually, assuming the package is built to be run on the -_same_ architectures, `configure' can figure that out, but if it prints -a message saying it cannot guess the machine type, give it the -`--build=TYPE' option. TYPE can either be a short name for the system -type, such as `sun4', or a canonical name which has the form: - - CPU-COMPANY-SYSTEM - -where SYSTEM can have one of these forms: - - OS - KERNEL-OS - - See the file `config.sub' for the possible values of each field. If -`config.sub' isn't included in this package, then this package doesn't -need to know the machine type. - - If you are _building_ compiler tools for cross-compiling, you should -use the option `--target=TYPE' to select the type of system they will -produce code for. - - If you want to _use_ a cross compiler, that generates code for a -platform different from the build platform, you should specify the -"host" platform (i.e., that on which the generated programs will -eventually be run) with `--host=TYPE'. - -Sharing Defaults -================ - - If you want to set default values for `configure' scripts to share, -you can create a site shell script called `config.site' that gives -default values for variables like `CC', `cache_file', and `prefix'. -`configure' looks for `PREFIX/share/config.site' if it exists, then -`PREFIX/etc/config.site' if it exists. Or, you can set the -`CONFIG_SITE' environment variable to the location of the site script. -A warning: not all `configure' scripts look for a site script. - -Defining Variables -================== - - Variables not defined in a site shell script can be set in the -environment passed to `configure'. However, some packages may run -configure again during the build, and the customized values of these -variables may be lost. In order to avoid this problem, you should set -them in the `configure' command line, using `VAR=value'. For example: - - ./configure CC=/usr/local2/bin/gcc - -causes the specified `gcc' to be used as the C compiler (unless it is -overridden in the site shell script). - -Unfortunately, this technique does not work for `CONFIG_SHELL' due to -an Autoconf limitation. Until the limitation is lifted, you can use -this workaround: - - CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash - -`configure' Invocation -====================== - - `configure' recognizes the following options to control how it -operates. - -`--help' -`-h' - Print a summary of all of the options to `configure', and exit. - -`--help=short' -`--help=recursive' - Print a summary of the options unique to this package's - `configure', and exit. The `short' variant lists options used - only in the top level, while the `recursive' variant lists options - also present in any nested packages. - -`--version' -`-V' - Print the version of Autoconf used to generate the `configure' - script, and exit. - -`--cache-file=FILE' - Enable the cache: use and save the results of the tests in FILE, - traditionally `config.cache'. FILE defaults to `/dev/null' to - disable caching. - -`--config-cache' -`-C' - Alias for `--cache-file=config.cache'. - -`--quiet' -`--silent' -`-q' - Do not print messages saying which checks are being made. To - suppress all normal output, redirect it to `/dev/null' (any error - messages will still be shown). - -`--srcdir=DIR' - Look for the package's source code in directory DIR. Usually - `configure' can determine that directory automatically. - -`--prefix=DIR' - Use DIR as the installation prefix. *note Installation Names:: - for more details, including other options available for fine-tuning - the installation locations. - -`--no-create' -`-n' - Run the configure checks, but stop before creating any output - files. - -`configure' also accepts some other, not widely useful, options. Run -`configure --help' for more details. diff --git a/archive_old_fs_versions/fuse-tutorial-2016-03-25/Makefile b/archive_old_fs_versions/fuse-tutorial-2016-03-25/Makefile deleted file mode 100644 index aae9f37350a62e6e81addac2b7469f4a9571224f..0000000000000000000000000000000000000000 --- a/archive_old_fs_versions/fuse-tutorial-2016-03-25/Makefile +++ /dev/null @@ -1,760 +0,0 @@ -# Makefile.in generated by automake 1.15 from Makefile.am. -# Makefile.

Callbacks and struct fuse_operations

-

-A FUSE filesystem is a program that listens on a socket for file -operations to perform, and performs them. The FUSE library -(libfuse) provides the communication with the socket, and -passes the requests on to your code. It accomplishes this by using a -"callback" mechanism. -

- -

-The callbacks are a set of functions you write to implement the -file operations, and a struct fuse_operations -containing pointers to them. -

- -

-In the case of BBFS, the callback struct is named -bb_oper. There are a total of 34 file operations -defined in bbfs.c with pointers in bb_oper. -The initialization uses a syntax that not everyone is familiar with; -looking at a part of the initialization of the struct we -see -

- -
-
-struct fuse_operations bb_oper = {
-  .getattr = bb_getattr,
-  .readlink = bb_readlink,
-  .open = bb_open,
-  .read = bb_read
-};
-
- -
-(this isn't the complete struct, of course — just enough to get -a sense of what's going on) -

- -

This indicates that bb_oper.getattr points to -bb_getattr(), bb_oper.readlink points to -bb_readlink(), bb_oper.open points to -bb_open(), and bb_oper.read points to -bb_read(). Each of these functions is my -re-implementation of the corresponding filesystem function: when a -user program calls read(), my bb_read() -function ends up getting called. In general, what all of my -reimplementations do is to log some information about the call, -and then call the original system implementation of the operation on -the underlyng filesystem. -

- -

-Let's take a look at two of these in particular: -bb_open() (my re-implementation of open(), -and bb_read() (my re-implementation of -read(). -

-

-Here's bb_open(): -

-
-int bb_open(const char *path, struct fuse_file_info *fi)
-{
-    int retstat = 0;
-    int fd;
-    char fpath[PATH_MAX];
-
-    bb_fullpath(fpath, path);
-    
-    log_msg("bb_open(fpath\"%s\", fi=0x%08x)\n",
-	    fpath,  (int) fi);
-    
-    fd = open(fpath, fi->flags);
-    if (fd < 0)
-	retstat = bb_error("bb_open open");
-    
-    fi->fh = fd;
-    log_fi(fi);
-    
-    return retstat;
-}
-
-

-When the function is called, it is passed two parameters: a -file path (which is relative to the root of the mounted file -system), and a pointer to a -struct fuse_file_info which is used to maintain -information about the file. -

-

-bb_open() starts by translating the relative path it was given -to a full path in the underlying filesystem using my -bb_fullpath() function. It then logs the full path, and -the address of the fi pointer. It passes the call on -down to the underlying fileystem, and sees if it was successful. If -it was, it stores away the file descriptor returned by -open() (so I'll be able to use it later), and returns 0. -If it failed, it returns -errno. About the return value: -

- -
    -
  1. - 0 should be returned on success. This is the normal behavior for - most of the calls in the libraries; exceptions are documented. -
    2. - -
  2. A negative return value denotes failure. If I return a value of - -i, a -1 will be returned to the caller and - errno is set to i. My - bb_error() function looks up errno as set - by the system open() call, logs the error, and returns - -errno to this function so I can pass it to the user.
    3. -
- -

-Notice that FUSE performs some translations. The -open() system call is documented as returning a file -descriptor (behavior I'm depending on), not 0 — so when my -return is passed to the original caller, FUSE recognizes that I sent a -0 and returns an appropriate file descriptor (not necessarily the same -one I got from my call to open()!). Meanwhile, I've got -the underlying file open, and I've got its file descriptor in -fi. Future calls to my code will include this pointer, so -I'll be able to get the file descriptor and work with it. So... the -user program has an open file in the mounted filesystem, and a file -descriptor that it is keeping track of. Whenever that program tries -to do anything with that file descriptor, the operation is intercepted -by the kernel and sent to the bbfs program. Within my -program, I also have a file open in the underlying directory, and a -file descriptor. When the operation is sent to my program, I'll log -it and then perform the same operation on my file. -

- -

-To make this concrete, let's take a look at bb_read(): -

-
-int bb_read(const char *path, char *buf, size_t size, off_t offset, struct fuse_file_info *fi)
-{
-    int retstat = 0;
-    
-    log_msg("bb_read(path=\"%s\", buf=0x%08x, size=%d, offset=%lld, fi=0x%08x)\n",
-	    path,  (int) buf, size,  offset,  (int) fi);
-    
-    retstat = pread(fi->fh, buf, size, offset);
-    if (retstat < 0)
-	retstat = bb_error("bb_read read");
-    
-    return retstat;
-}
-
-
-

-This function allows us to read data from some specified offset from -the beginning of a file (so it corresponds more directly to the -pread() function than to read()). -

-

-The main thing to point out about this function is that I use my file -descriptor, which I put in fi when I opened the file, to -read it. Also, if I get a non-error return from pread(), -I pass this value up to the caller. In this case FUSE -doesn't perform any translations, it just returns the value I gave -it. To return an error, I use the same technique as in -bb_open(). -

Files and Naming Conventions

-

Before we get into the details of using FUSE, and of the Big - Brother File System, let's see how the files are organized. -

-

The code for the BBFS running example is in subdirectory ../src

- -

-

Makefile -
As usual, a Makefile is used to direct the - compilation of the code. The code is so simple that I just - hard-coded a Makefile rather than using automake; it requires - pkg-config (and of course FUSE!), but everything else - ought to be available in any Linux system used for development. -

-

-

bbfs.c -
The code re-implementing the Linux file operations is in - this file. Every function defined in this file starts with - bb_, so it's easy to tell my code from system - code. -

-

- The file also contains a - struct fuse_operations  named - bb_oper, containing pointers to the functions (we'll - discuss this struct in the next section) -

-

- The functions that are pointed to by fields in the - struct fuse data structure all have names - derived from their field names by prepending the standard - bb_ prefix. So, for instance, the - open() function is bb_open(). -

-

-

log.c and log.h -
The logging code, reporting all the operations that are - performed, is in log.c. Their names all start with - log_, again to help identify the logging code. - log.h contains prototypes for the functions that - are called from elsewhere (and, of course, the only "elsewhere" - in this project is bbfs.c). -

-

-

params.h -
This defines which version of the FUSE API is being used, - defines a symbol that give me access to the pread() - system call, and defines a struct bb_state - that stores filesystem state. -

-
- -

-I should also mention that nearly all of the documentation on FUSE -itself is in the #include file -/usr/include/fuse/fuse.h. This is where prototypes are -given for all functions, and comments describe their use. My -bbfs.c file started as a copy of that file, with my code -inserted. -

Parsing the Command Line and Initializing FUSE

-

-You actually have to do very little command-line parsing: FUSE -understands a large number of command-line arguments, and parses -them itself. Most importantly, FUSE expects the mountpoint to be one -of the members of the argv[] array. -

-

-I'm simplifying things for myself by assuming that the root directory -and mount point will be the last two arguments on the command line, -with the root directory preceding the mount point. So, my command -line parsing happens in two short sections. First, I do some sanity -checking: I make sure I've got enough arguments on the command line, -and that the last two arguments aren't options. -

-
-
-if ((argc < 3) || (argv[argc-2][0] == '-') || (argv[argc-1][0] == '-'))
-    bb_usage();
-
-
-

-A few lines later, I pull the root directory out of the argument list, -use the C library realpath() function to translate it to -a canonicalized absolute pathname, and save it in my private data -(I'll be describing private data in the next section)

-
-
-bb_data->rootdir = realpath(argv[argc-2], NULL);
-argv[argc-2] = argv[argc-1];
-argv[argc-1] = NULL;
-argc--;
-
-
-

-The last thing I do before turning control over to the FUSE library is -to open the log file, and save its stream pointer in my private data -as well. -

-

-Once I'm ready to start the filesystem, I call -fuse_main(). Its parameters are argc and -argv (as modified by my main() function), -the bb_oper struct containing pointers to my -re-implementations of the POSIX file operations, and a -struct bb_data, used for storing private data. -

-

fuse_main() parses the rest of the command line, -mounts the directory specified on the command line, and performs other -initializations. Then, it calls an initialization function to -perform any initialization defined by my code. bb_oper->init -points to my bb_init() function, so it is what gets called. -My bb_init() function is really small; all it does is -log the fact that it has been called. -

Private Data

-

-One more piece of information on using FUSE that's very helpful is -how it lets you store and access data that you've defined. -

-

-FUSE has a struct fuse_context which contains a -little bit of extra information about a filesystem. One very useful -field in this struct is -void* private_data, a pointer to arbitrary data -stored by your filesystem. -

-

-From inside any FUSE operation, it's possible to obtain the context by -calling fuse_get_context(); this means we can use -fuse_get_context()->private_data to get the private data. -

-

-We can see how to use this by looking at my log_msg() -function. Here it is: -

-
-void log_msg(const char *format, ...)
-{
-    va_list ap;
-    va_start(ap, format);
-
-    vfprintf(BB_DATA->logfile, format, ap);
-}
-
-

-It uses a macro I defined:

-
-
-#define BB_DATA ((struct bb_state *) fuse_get_context()->private_data)
-
-
-

-to obtain the private data field and cast it to a -struct bb_state *. -

-

-You can see how I created the struct bb_struct by -looking at params.h where I defined the -struct: -

-
-struct bb_state {
-    FILE *logfile;
-    char *rootdir;
-};
-
-

It has two fields: the FILE* for the log file, and -the path to the directory we're accessing through BBFS. -

-

-I malloc() the structure and set the values of the -fields in my main() function (see last section) so -they'll be available to me later. -

Configuring, Compiling and Running

-

-This page of the tutorial explains how to build the BBFS filesystem -program and use it to mount a directory. -

-

Configuring and Compiling

-

This tutorial uses the GNU autotools system for configuration. As -is the case with all autotools-based projects, you can configure and -compile it by going to the top-level directory and typing -

-
-./configure
-make
-
-
-and the code should be compiled and ready to go.

-

-Unlike most software, the code from this tutorial is not intended to -be installed. Consequently, I've tried to disable all the various -installation targets; if I've missed one please let me know. -

-

Mounting a BBFS Filesystem

-

-You mount a BBFS filesystem by running the command bbfs -(in general, a FUSE filesystem is implemented by a program, and you -mount it by running that program). -bbfs has two required arguments: the root directory (which -contains the actual directory data) and the mount directory. The -tutorial tarball includes an example directory, which -contains two subdirectories named rootdir and -mountdir. You can verify that rootdir -contains a single file named bogus.txt, while -mountdir is empty -

-

Here's what it looks like when you try it:

-

-snowball:655$ pwd
-/home/joseph/fuse-tutorial/example
-snowball:656$ ls -lR
-.:
-total 12
--rw-r--r-- 1 joseph users  185 Jun  9 15:56 Makefile
-drwxr-xr-x 2 joseph users 4096 Jun 12 17:16 mountdir/
-drwxr-xr-x 2 joseph users 4096 Jun 12 17:16 rootdir/
-
-./mountdir:
-total 0
-
-./rootdir:
-total 4
--rw-r--r-- 1 joseph users 11 Jun 12 17:16 bogus.txt
-
-

Now, if you go into the example directory and execute

-
-../src/bbfs rootdir mountdir
-
-

all of the files that are really in rootdir appear to also -be in mountdir" -

-

-snowball:657$ ../src/bbfs rootdir/ mountdir/
-about to call fuse_main
-snowball:658$ ls -lR
-.:
-total 40
--rw-r--r-- 1 joseph users   185 Jun  9 15:56 Makefile
--rw-r--r-- 1 joseph users 25632 Jun 12 17:51 bbfs.log
-drwxr-xr-x 2 joseph users  4096 Jun 12 17:16 mountdir/
-drwxr-xr-x 2 joseph users  4096 Jun 12 17:16 rootdir/
-
-./mountdir:
-total 4
--rw-r--r-- 1 joseph users 11 Jun 12 17:16 bogus.txt
-
-./rootdir:
-total 4
--rw-r--r-- 1 joseph users 11 Jun 12 17:16 bogus.txt
-
-
-

-But, every time you perform any file -operation in mountdir, the operation (and a whole bunch -of both relevant and irrelevant stuff) gets logged to a new file in the -current working directory called bbfs.log If you execute

-
-tail -F bbfslog
-
-

in another terminal window, you can watch the operations get -logged.

-

Finally, you can see that the operating system sees -mountdir as a filesystem:

-

-snowball:660$ mount | grep mountdir
-bbfs on /home/joseph/fuse-tutorial/example/mountdir type fuse.bbfs (rw,nosuid,nodev,relatime,user_id=1248,group_id=1005)
-
-

Unmounting

-

Finally, you can unmount the filesystem with

-
-snowball:661$ fusermount -u mountdir
-snowball:662$ ls -lR
-.:
-total 40
--rw-r--r-- 1 joseph users   185 Jun  9 15:56 Makefile
--rw-r--r-- 1 joseph users 27520 Jun 12 17:57 bbfs.log
-drwxr-xr-x 2 joseph users  4096 Jun 12 17:16 mountdir/
-drwxr-xr-x 2 joseph users  4096 Jun 12 17:16 rootdir/
-
-./mountdir:
-total 0
-
-./rootdir:
-total 4
--rw-r--r-- 1 joseph users 11 Jun 12 17:16 bogus.txt
-
-

(note that fusermount isn't part of this tutorial -— it comes along with FUSE).

- -

pkg-config

-

One thing to mention about configuring the software is the line -

PKG_CHECK_MODULES(FUSE, fuse)
-in configure.ac -

-

-This translates to two invocations of pkg-config to -obtain the C compilation flags and libraries needed to compile and -link the code in the tutorial. -

-
-`pkg-config fuse --cflags`
-
-

says to use pkg-config to determine what C -compiler flags are necessary to compile a source file that makes use -of FUSE. The back-quotes around the command are important — -they take the output of the command and insert it into the -command-line as command-line operations (note — it's important -those are back-quotes aka accent graves. They can't be forward quotes, -nor double quotes). The other place it's used, -

-`pkg-config fuse --libs`
-
-

-gives the extra command-line arguments to link the program with -libfuse. -

-

-An earlier version of this tutorial used these invocations directly in -the Makefile, like this: -

-

-bbfs : bbfs.o log.o
-        gcc -g -o bbfs bbfs.o log.o `pkg-config fuse --libs`
-
-bbfs.o : bbfs.c log.h params.h
-        gcc -g -Wall `pkg-config fuse --cflags` -c bbfs.c
-
-log.o : log.c log.h params.h
-        gcc -g -Wall `pkg-config fuse --cflags` -c log.c

Privilege Escalation

-

-The main point -to make is that the filesystem itself executes with the access -privileges of the process running it, not those of the -process making use of the filesystem. Here's how this plays -out in some typical scenarios:

- -

The Common Case: a User Runs the Filesystem Without the -allow_other Option

-

-This is the normal case; the filesystem runs with the privileges of -the user that ran it, and only that user can access the filesystem. -FUSE doesn't open up any particular security issues in this case. -

- -

A User Runs the Filesystem With the allow_other -Option

-

-In this case, the filesystem runs with the privileges of the user -that invoked it, not the privileges of any user who happens -to make use of the filesystem. It's the responsibility of the user who -mounts the filesystem to ensure inappropriate access privileges aren't -being granted to other users. In general, users can only hurt -themselves this way, since they can only grant privileges that they -themselves already have. -

-

-It should be noted that an option, user_allow_other, must -be set in /etc/fuse.conf to enable this option. -

-

Root Runs a Filesystem

-

-This is really the same as the previous two cases (depending on -whether the allow_other option is set), but root is a -sufficiently special case that it deserves mention. In this case, any -user making use of the filesystem has root privileges on that -filesystem! If the process has access to the actual filesystem, this -could easily be used to gain pretty much unlimited access. -

-

-The next subsection will talk a little bit about checking access -rights, but the simplest way out here is to not allow root to mount the -filesystem. Due to BBFS's intended role as a simple tutorial, that's -what I do. There's a little bit of code right at the start of -main(): - -

-if ((getuid() == 0) || (geteuid() == 0)) {
-    fprintf(stderr, "Running BBFS as root opens unnacceptable security holes\n");
-    return 1;
-}
-
- -

-

-Of course, this means that while I've got code for -bb_chown(), it doesn't actually work since only root is -able to change the ownership of a file in the underlying filesystem. -

-

Checking Access Rights

-

-In general, a filesystem that might be executed with the -allow_other flag will need to take steps to ensure its -own security. fuse.h documents that several calls -need to check that the requested access is permitted; in addition to -those, there are several others that also require access checks (such -as chown(). It is strictly the programmer's -responsibility to make sure these cautions are followed! -

-

-The most important function for checking access rights is -fuse_get_context() which (as the name implies) returns a -pointer to a struct fuse_context object. The UID and GID -of the process performing the operation is in fields named -uid and gid. -

- -

Simultaneous Access and Race Conditions

-

-By default, FUSE runs multi-threaded: this means (in brief) that a -second request can be handled by the filesystem before an earlier -request has completed; this in turn raises the possibility that -different threads can be simultaneously modifying a single data -structure, which will cause very difficult-to-debug bugs. -

-

There are a couple of things that can be done about the -problem:

-
    -
  • - If the filesystem is executed with the -s option, - it is run single-threaded. this eliminates the problem, at a cost - in performance -- frankly, given the nature and intent of many fuse - filesystems, it seems to me like the default should be - single-threaded and multi-threaded should require an option. But I - didn't write it, so it's not my call. -
    • -
  • - You can analyse your code for critical sections, and insert the - normal syncronization primitives (such as semaphores) to ensure no - dangerous races occur. Of course, there are several places where - FUSE translates a single call into a sequence of calls to your - functions; I haven't investigated whether FUSE takes any steps to - ensure the atomicity of these calls. If it doesn't (and I suspect - that's the case; trying to do so in any meaningful way in the absence - of knowledge of the data you're exposing through your filesystem - seems somewhere between difficult and impossible to me), then trying - to do it yourself seems really, really hard. -
    • -
-

Note that even if you do make your filesystem single-threaded, that -doesn't guard against access to the underlying data structures through -some other means. Taking BBFS as an example:

-
    -
  • - You can have a single underlying directory mounted through two - different mountpoints by using two invocations of bbfs. -
    • -
  • - A directory that has a BBFS filesystem mounted on top of it is still - accessible to normal filesystem operations. -
    • -
-

-Either of these facts is sufficient to completely negate any efforts -made in your filesystem to guard atomicity. -

-

-I should note that the FUSE code itself is careful about locking its -own code and data structures. So far as I know, dangerous race -conditions won't occur outside of your code. -

Extra Information on Unclear FUSE Functions

-

-The intent of this page is to give a little bit of extra information -on calls that seem a little obscure in the FUSE documentation. Two -cases requiring extra explanation have come up so far: -readdir(), and FUSE's handling of the file creation flags -in open(). -

-

Directories and readdir()

-

-FUSE provides a mechanism to place entries in a -directory structure. The directory structure itself is opaque, so the -basic mechanism is to create the data and call a FUSE-supplied -function to put it in the structure. -

- -

-When your readdir() callback is invoked, one of -the parameters is a function called filler(). The -purpose of this function is to insert directory entries into the -directory structure, which is also passed to your callback as -buf. -

- -

-filler()'s prototype looks like this: -

-
-
-int fuse_fill_dir_t(void *buf, const char *name,
-				const struct stat *stbuf, off_t off);
-
 -
- -

-You insert an entry into buf (the same buffer that -is passed to readdir()) by calling -filler() with the filename and optionally a -pointer to a -struct stat containing the file type. -

- -

-bb_readdir() uses filler() in as -simple a way as possible to just copy the underlying directory's -filenames into the mounted directory. Notice that the offset passed -to bb_readdir() is ignored, and an offset of 0 is -passed to filler(). This tells filler() -to manage the offsets into the directory structure for itself. Here's -the code: -

-
-int bb_readdir(const char *path, void *buf, fuse_fill_dir_t filler, off_t offset,
-               struct fuse_file_info *fi)
-{
-    int retstat = 0;
-    DIR *dp;
-    struct dirent *de;
-    
-    log_msg("bb_readdir(path=\"%s\", buf=0x%08x, filler=0x%08x, offset=%lld, fi=0x%08x)\n",
-            path, (int) buf, (int) filler,  offset, (int) fi);
-    
-    dp = (DIR *) (uintptr_t) fi->fh;
-
-    // Every directory contains at least two entries: . and ..  If my
-    // first call to the system readdir() returns NULL I've got an
-    // error; near as I can tell, that's the only condition under
-    // which I can get an error from readdir()
-    de = readdir(dp);
-    if (de == 0)
-        return -errno;
-
-    // This will copy the entire directory into the buffer.  The loop exits
-    // when either the system readdir() returns NULL, or filler()
-    // returns something non-zero.  The first case just means I've
-    // read the whole directory; the second means the buffer is full.
-    do {
-        log_msg("calling filler with name %s\n", de->d_name);
-        if (filler(buf, de->d_name, NULL, 0) != 0)
-            return -ENOMEM;
-    } while ((de = readdir(dp)) != NULL);
-    
-    log_fi(fi);
-    
-    return retstat;
-}
-

File Creation Flags

-

The open() system call is documented as taking both file -access mode and file creation flags (the file creation flags are -O_CREAT, O_EXCL, O_NOCTTY, and -O_TRUNC). fuse.h documents that -O_CREAT and O_EXCL are not passed to your -open() function, and further that O_TRUNC is -not passed by default. -

-

The reason for this turns out to be that FUSE handles these flags -internally, and modifies which of your functions are called depending -on their status, and on the results of a call to your -getattr() (your getattr() is always called -before the file is opened). If those flags are set, the call is handled -as follows: -

-
- -

-

O_CREAT -
If the file didn't previously exist, your create() - function is called instead of your open() function - (if it did exist, then your open() is called). After - the call to your create() function, your - fgetattr() function is called, though I haven't been - able to determine why. One possible use is that you could use - this to modify the semantics of creating a file that you yourself - don't have access to (note that the standard semantics will only - apply the file access mode you specify to subsequent - open()s). -

-

- If the file did not exist, and the flag is not set, FUSE only - calls your getattr() function (so neither your - create() nor your open() function is - called in this case). -

- -

-

O_EXCL -
The behavior of this flag is only defined when - O_CREAT is also specified. If the file did not - previously exist your create() and - fgetatter()functions are called; if it did, FUSE returns - failure after the getattr() call (so neither your - open() nor your create() is called in this - case). -

- -

-

O_NOCTTY -
So far as I've been able to determine, this flag is simply - discarded. -

- -

-

O_TRUNC -
Handling of this flag is determined by whether or not the - filesystem is mounted with the -o atomic_o_trunc - flag. If not, then FUSE will call your truncate() - function before calling your open(). If the - atomic_o_trunc option was set, the flag is passed to - your open() function instead (note that this means I - don't have any code that explicitly handles the flag: if it gets - passed to bb_open(), I just pass it along to - open(). -

Writing a FUSE Filesystem: a Tutorial

Version of 2016-03-25

-

One of the real contributions of Unix has been the view that -"everything is a file". A tremendous number of radically -different sorts of objects, from data storage to file format -conversions to internal operating system data structures, have been -mapped to the file abstraction. -

- -

-One of the more recent directions this view has taken has been -Filesystems in User Space, or FUSE (no, the acronym really doesn't -work. Oh well). The idea here is that if you can envision -your interaction with an object in terms of a directory structure -and filesystem operations, you can write a FUSE file system to -provide that interaction. You just write code that implements -file operations like open(), read(), and -write(); when your filesystem is mounted, programs -are able to access the data using the standard file operation -system calls, which call your code. -

-

-FUSE filesystems have been written to do everything from providing -remote access to files on a different host without using NFS or CIFS -(see SSHFS at https://github.com/libfuse/sshfs) to implementing a filesystem to -talk to devices using the Media Transfer protocol (see jmtpfs at https://github.com/kiorky/jmtpfs) to organizing a music -collection with directories based on MP3 tags (see id3fs at http://erislabs.net/ianb/projects/id3fs/id3fsd.html) to, really, -almost anything. The possibilities are only limited by your -imagination! -

-

-There are many documents on the web describing how FUSE works and -how to install and use a FUSE filesystem, but I haven't come across -any that try to describe how to go about actually writing one. The -goal of this tutorial is to meet what I see as a need for such a -document. -

- -

-This tutorial introduces FUSE using a filesystem I call the "Big Brother -File System" (the reason for the name is that "Big Brother is -watching"). The filesystem simply passes every operation down to an -underlying directory, but logs the operation. -

- -

-This tutorial, together with its associated example filesystem, is -available as a tarball at - -http://www.cs.nmsu.edu/~pfeiffer/fuse-tutorial.tgz. -

- -

-Audience: This tutorial is aimed at developers who have some -familiarity with general programming in Linux (and Unix-like operating -systems in general), so you know how to untar a tarball, how Makefiles -work, and so forth. I won't be going through the details of how to -perform those tasks; I'll be focussing on what you need to know that's -specific to using FUSE filesystems. -

- -

-I am not affiliated with the FUSE project in any way, except as a -user. My descriptions of the interface to fuse, and of techniques to -work with it, are a distillation of my reading of the existing -documentation, and my experience working with it. Consequently, any -errors are mine (and corrections are welcome!). -

This work was produced at the University of -California, Lawrence Livermore National Laboratory under Contract No. -W-7405-ENG-48 with the DOE. - -B.

This License applies to any program or other work which contains a notice -placed by the copyright holder saying it may be distributed under the terms of -this General Public License. The "Program," below, refers to any such program -or work, and a "work based on the Program" means either the Program or any -derivative work under copyright law: that is to say, a work containing the -Program or a portion of it, either verbatim or with modifications and/or -translated into another language. (Hereinafter, translation is included -without limitation in the term "modification".) Each licensee is addressed as -"you." - -Activities other than copying, distribution and modification are not covered by -this License; they are outside its scope. The act of running the Program is -not restricted, and the output from the Program is covered only if its contents -constitute a work based on the Program (independent of having been made by -running the Program). Whether that is true depends on what the Program does. - -1. You may copy and distribute verbatim copies of the Program's source code as -you receive it, in any medium, provided that you conspicuously and -appropriately publish on each copy an appropriate copyright notice and -disclaimer of warranty; keep intact all the notices that refer to this License -and to the absence of any warranty; and give any other recipients of the -Program a copy of this License along with the Program. - -You may charge a fee for the physical act of transferring a copy, and you may -at your option offer warranty protection in exchange for a fee. - -2. You may modify your copy or copies of the Program or any portion of it, -thus forming a work based on the Program, and copy and distribute such -modifications or work under the terms of Section 1 above, provided that you -also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices stating - that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in whole - or in part contains or is derived from the Program or any part thereof, - to be licensed as a whole at no charge to all third parties under the terms - of this License. - - c) If the modified program normally reads commands interactively when run, - you must cause it, when started running for such interactive use in the - most ordinary way, to print or display an announcement including an - appropriate copyright notice and a notice that there is no warranty (or - else, saying that you provide a warranty) and that users may redistribute - the program under these conditions, and telling the user how to view a copy - of this License. (Exception: if the Program itself is interactive but does - not normally print such an announcement, your work based on the Program is - not required to print an announcement.) - -These requirements apply to the modified work as a whole. If identifiable -sections of that work are not derived from the Program, and can be reasonably -considered independent and separate works in themselves, then this License, and -its terms, do not apply to those sections when you distribute them as separate -work. But when you distribute the same section as part of a whole which is a -work based on the Program, the distribution of the whole must be on the terms -of this License, whose permissions for other licensees extend to the entire -whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest your -rights to work written entirely by you; rather, the intent is to exercise the -right to control the distribution of derivative or collective works based on -the Program. - -In addition, mere aggregation of another work not based on the Program with the -Program (or with a work based on the Program) on a volume of a storage or -distribution medium does not bring the other work under the scope of this -License. - -3. You may copy and distribute the Program (or a work based on it, under -Section 2) in object code or executable form under the terms of Sections 1 and -2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable source - code, which must be distributed under the terms of Sections 1 and 2 above - on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three years, to - give any third party, for a charge no more than your cost of physically - performing source distribution, a complete machine-readable copy of the - corresponding source code, to be distributed under the terms of Sections 1 - and 2 above on a medium customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer to - distribute corresponding source code. (This alternative is allowed only - for noncommercial distribution and only if you received the program in - object code or executable form with such an offer, in accord with - Subsection b above.) - -The source code for a work means the preferred form the work for making -modifications to it. For an executable work, complete source code means all -the source code for all modules it contains, plus any associated interface -definition files, plus the scripts used to control compilation and installation -of the executable. However, as a special exception, the source code -distributed need not include anything that is normally distributed (in either -source or binary form) with the major components (compiler, kernel, and so on) -of the operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the source -code from the same place counts as distribution of the source code, even though -third parties are not compelled to copy the source along with the object code. - -4. You may not copy, modify, sublicense, or distribute the Program except as -expressly provided under this License. Any attempt otherwise to copy, modify, -sublicense or distribute the Program is void, and will automatically terminate -your rights under this License. However, parties who have received copies, or -rights, from you under this License will not have their licenses terminated so -long as such parties remain in full compliance. - -5. You are not required to accept this License, since you have not signed it. -However, nothing else grants you permission to modify or distribute the Program -or its derivative works. These actions are prohibited by law if you do not -accept this License. Therefore, by modifying or distributing the Program (or -any work based on the Program), you indicate your acceptance of this License to -do so, and all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - -6. Each time you redistribute the Program (or any work based on the Program), -the recipient automatically receives a license from the original licensor to -copy, distribute or modify the Program subject to these terms and conditions. -You may not impose any further restrictions on the recipients' exercise of the -rights granted herein. You are not responsible for enforcing compliance by -third parties to this License. - -7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), conditions -are imposed on you (whether by court order, agreement or otherwise) that -contradict the conditions of this License, they do not excuse you from the -conditions of this License. If you cannot distribute so as to satisfy -simultaneously your obligations under this License and any other pertinent -obligations, then as a consequence you may not distribute the Program at all. -For example, if a patent license would not permit royalty-free redistribution -of the Program by all those who receive copies directly or indirectly through -you, then the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under any -particular circumstance, the balance of the section is intended to apply and -the section as a whole is intended to apply in other circumstances. - -It is not the purpose to this section to induce you to infringe any patents or -other property right claims or to contest validity of any such claims; this -section has the sole purpose of protecting the integrity of the free software -distribution system, which is implemented by public license practices. Many -people have made generous contributions to the wide range of software -distributed through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing to -distribute software through any other system and a licensee cannot impose that -choice. - -This section is intended to make thoroughly clear what is believed to be a -consequence of the rest of this License. - -8. If the distribution and/or use of the Program is restricted in certain -countries either by patents or by copyrighted interfaces, the original -copyright holder who places the Program under this License may add an explicit -geographical distribution limitation excluding those countries, so that -distribution is permitted only in or among countries not thus excluded. In -such case, this License incorporates the limitation as if written in the body -of this License. - -9. The Free Software Foundation may publish revised and/or new versions of the -General Public License from time to time. Such new versions will be similar in -spirit to the present version, but may differ in detail to address new problems -or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any later -version," you have the option of following the terms and conditions either of -that version of any later version published by the Free Software Foundation. -If the Program does not specify a version number of this License, you may -choose any version ever published by the Free Software Foundation. - -10. If you wish to incorporate parts of the Program into other free programs -whose distribution conditions are different, write to the author to ask for -permission. For software which is copyrighted by the Free Software Foundation, -write to the Free Software Foundation; we sometimes make exceptions for this. -Our decision to grant permission will be guided by the two goals of preserving -the free status of all derivatives of our free software and or promoting the -sharing and reuse of software generally. - -NO WARRANTY - -11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR -THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE -STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE -PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, -INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND -FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND -PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, -YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - -12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL -ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE -PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY -GENERAL, SPECIAL INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR -INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA -BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A -FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER -OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. - -END OF TERMS AND CONDITIONS diff --git a/benchmarks/mdtest-1.9.3-modified/Makefile b/benchmarks/mdtest-1.9.3-modified/Makefile deleted file mode 100644 index be19a98b2a46a78430d106d06741e81c01671df9..0000000000000000000000000000000000000000 --- a/benchmarks/mdtest-1.9.3-modified/Makefile +++ /dev/null @@ -1,62 +0,0 @@ -#/*****************************************************************************\ -#* * -#* Copyright (c) 2003, The Regents of the University of California * -#* See the file COPYRIGHT for a complete copyright notice and license. * -#* * -#******************************************************************************* -#* -#* CVS info: -#* $RCSfile: Makefile,v $ -#* $Revision: 1.2 $ -#* $Date: 2013/04/16 16:43:51 $ -#* $Author: brettkettering $ -#* -#* Purpose: -#* Make mdtest executable. -#* -#* make [mdtest] -- mdtest -#* make clean -- remove executable -#* -#\*****************************************************************************/ - -CC.AIX = mpcc_r -bmaxdata:0x80000000 -CC.Linux = mpicc -Wall -# -# For Cray systems -#CC.Linux = ${MPI_CC} -CC.Darwin = mpicc -Wall - -# Requires GNU Make -OS=$(shell uname) - -# Flags for compiling on 64-bit machines -LARGE_FILE = -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE=1 -D__USE_LARGEFILE64=1 - -CC = $(CC.$(OS)) - -# -# One needs someting like the following code snippet in one's cshrc file is one -# plans to use PLFS with mdtest. -# -# -# If we're not going to use PLFS with mdtest, we don't need to define this variable. -# -# setenv MDTEST_FLAGS "" -# -# If we're going to use PLFS with mdtest, we need to define this variable based on -# whether we are loading a PLFS module or using the system default PLFS installation. -# -# if ( $?PLFS_CFLAGS ) then -# setenv MDTEST_FLAGS "-D_HAS_PLFS ${PLFS_CFLAGS} ${PLFS_LDFLAGS}" -# else -# setenv MDTEST_FLAGS "-D_HAS_PLFS -I${MPICH_DIR}/include -lplfs" -# endif - - -all: mdtest - -mdtest: mdtest.c - $(CC) -D$(OS) $(LARGE_FILE) $(MDTEST_FLAGS) -g -o mdtest mdtest.c `pkg-config --cflags --libs glib-2.0` -lm - -clean: - rm -f mdtest mdtest.o diff --git a/benchmarks/mdtest-1.9.3-modified/README b/benchmarks/mdtest-1.9.3-modified/README deleted file mode 100644 index e6ce3cfb6b7a28d37e9183796f5c8a893048d69a..0000000000000000000000000000000000000000 --- a/benchmarks/mdtest-1.9.3-modified/README +++ /dev/null @@ -1,136 +0,0 @@ -/******************************************************************************\ -* * -* Copyright (c) 2003, The Regents of the University of California * -* See the file COPYRIGHT for a complete copyright notice and license. * -* * -\******************************************************************************/ - -Usage: mdtest [-b #] [-B] [-c] [-C] [-d testdir] [-D] [-e] [-E] [-f first] [-F] - [-h] [-i iterations] [-I #] [-l last] [-L] [-n #] [-N #] [-p seconds] - [-r] [-R[#]] [-s #] [-S] [-t] [-T] [-u] [-v] [-V #] [-w #] [-y] - [-z #] - - -b: branching factor of hierarchical directory structure - -B: no barriers between phases (create/stat/remove) - -c: collective creates: task 0 does all creates and deletes - -C: only create files/dirs - -d: the directory in which the tests will run - -D: perform test on directories only (no files) - -e: number of bytes to read from each file - -E: only read files - -f: first number of tasks on which the test will run - -F: perform test on files only (no directories) - -h: prints help message - -i: number of iterations the test will run - -I: number of items per tree node - -l: last number of tasks on which the test will run - -L: files/dirs created only at leaf level - -n: every task will create/stat/remove # files/dirs per tree - -N: stride # between neighbor tasks for file/dir stat (local=0) - -p: pre-iteration delay (in seconds) - -r: only remove files/dirs - -R: randomly stat files/dirs (optional seed can be provided) - -s: stride between the number of tasks for each test - -S: shared file access (file only, no directories) - -t: time unique working directory overhead - -T: only stat files/dirs - -u: unique working directory for each task - -v: verbosity (each instance of option increments by one) - -V: verbosity value - -w: number of bytes to write to each file - -y: sync file after write completion - -z: depth of hierarchical directory structure - -NOTES: - * -N allows a "read-your-neighbor" approach by setting stride to - tasks-per-node.

So, a target of I/O testing can be a - PLFS file system. - - To control whether or not mdtest is built with PLFS, one needs something - like the following cshrc code segment: - -# -# If we're not going to use PLFS with mdtest, we don't need to define this variable. -# -# setenv MDTEST_FLAGS "" -# -# If we're going to use PLFS with mdtest, we need to define this variable based on -# whether we are loading a PLFS module or using the system default PLFS installation. -# - if ( $?PLFS_CFLAGS ) then - setenv MDTEST_FLAGS "-D_HAS_PLFS ${PLFS_CFLAGS} ${PLFS_LDFLAGS}" - else - setenv MDTEST_FLAGS "-D_HAS_PLFS -I${MPICH_DIR}/include -lplfs" - endif - - * Changed the item count variables to be unsigned long long so that a - test can be run with more than 2^31-1 (max value of int) items. - - * Fixed the remove process so that all of the directories that mdtest - creates get deleted if the remove flag is set. Before the #test.0 - class of directories remained with no files in them. - -Changes in mdtest-1.8.4 - * Added read option to extend create (write) capability. New feature will: - -E: Only perform the read phase of the tests. - -e #: Set the number of Bytes to read from each file. - -Fixes in mdtest-1.8.3 - * Prepared for release on sourceforge.net - -Fixes in mdtest-1.8.2 - * With the new changes issued in mdtest-1.8.0, all files and directories - were operated upon by using the full path to each file/dir. Full paths - are no longer used. Now a relative path is used from the root dir of - each directory tree. - * fixed bug in collective creates and unique directory per task mode - -Fixes in mdtest-1.8.1 - * A new test directory is created for each iteration. Then for each - iteration the directory structure is created/removed. This allowed - multiple iterations of the create-only mode. The name of the test - directories has changed as a result of this fix. Also, aggregate - creation/removal times are computed now over the number of iterations. - -Changes in mdtest-1.8.0 - * added option to create files/dirs in tree-like directory structure: - Previously, all files/dirs were created in one test directory. Now the - root directories of the tree(s) are created in that test directory. - Files/dirs are then created within those root directories or their children. - If the -u flag is specified, then unique trees are created per proc. - Otherwise, one tree is created. This coincides with the previous - functionality. The following flags were added/changed to incorporate this - new feature: - -z #: Indicates the depth of the leaves of the tree. If this flag is not - specified, the depth defaults to 0 (i.e. files/dirs are created in - the top-level directories). - -b #: Indicates the branching factor of the tree. If this flag is not - specified, the branching factor defaults to 1. Branching factor - indicates the number of children that each non-leaf node has. - -L: Indicates that files/dirs should only be created at the leaf level - of the tree. - -I #: Indicates the number of files/dirs that should be created within - each directory of the tree. - -n #: This flag still indicates the total number of files/dirs that should - be created. However, with the new tree structure some calculations - are done to determine the number of files that should be created per - directory in the tree. Due to rounding the actual total number of - files may differ slightly from what is specified. - - * added option to choose which phases to run: - The create, stat, and remove phases of mdtest have been separated. There - are flags now that allow the user to choose which phases they want to - perform. If none of these flags is specified, then the default usage is - to do all of the phases. The user is trusted to be intelligent about their - choice of phases. As a result of the separation of the phases, the naming - convention of the files/dirs had to be altered slightly. - - * added option to not barrier between each phase (create/stat/remove): - A major change in mdtest is the ability to time each proc that is running - the different phases of mdtest. The default functionality is the same as - the previous version - barriers are taken between phases (create/stat/ - remove). Also, in the default case, the resultant times reflect the - slowest rates for each phase. If the -B flag is specified, then no barriers - are taken between the phases. There is a race condition when specifying - this flag, but it is rarely met. The race condition is that one proc might - be trying to remove a file in the shared file case before someone else has - a chance to stat the file. Also, when the -B flag is specified, the - resultant rates are aggregates over the number of iterations and the number - of procs used. The default case, as mentioned above, calculates aggregates - only over the number of iterations where the time for each phase of an - iteration is the time of the slowest proc for that particular phase. - - * added option to stat files/dirs in a random order: - The default usage of mdtest will stat files in sequential order. Now, - however, items can be stat'ed in a random order by specifying the -R flag. - Even though the stat order is random with this usage, items are still only - stat'ed once each. This is achieved by randomly sorting a list of unique - item IDs before running the different tests. A seed for the random number - generator can optionally be provided with the following syntax: -R#. - -Fixes in mdtest-1.7.5 - * changed bug in how test directory was created (race condition) - * added multipath option for test directories ('-d path1@path2@path3') - * added man page and correct malloc error-checking (patches from Jim Garlick) - -Fixes in mdtest-1.7.4: - * folded b_remove_0 branch into main HEAD branch - -Fixes in mdtest-b_remove_0: - * added remove option to only remove files from previous run - -Fixes in mdtest-pre_b_remove_0: - * simple clean up for preparing for branch - -Fixes in mdtest-1.7.3: - * added statfs() to get file system data block and inode usage, replacing - system() call - -Fixes in mdtest-1.7.2: - * initialized declared variables - * modified df disk usage call - * added error-checking for chdir() - -Fixes in mdtest-1.7.1: - * added '-y' option to sync file after write diff --git a/benchmarks/mdtest-1.9.3-modified/mdtest.1 b/benchmarks/mdtest-1.9.3-modified/mdtest.1 deleted file mode 100644 index ba82d88a966948be99ddf9672c63bf72911968c3..0000000000000000000000000000000000000000 --- a/benchmarks/mdtest-1.9.3-modified/mdtest.1 +++ /dev/null @@ -1,188 +0,0 @@ -.TH mdtest 1 "2010-05-05" "mdtest-1.8.3" "mdtest" -.SH NAME -mdtest \- test file system metadata performance -.SH SYNOPSIS -.B mdtest -.I "[-options]" -.SH DESCRIPTION -.B mdtest -is a file system metadata performance test designed to run -in a cluster MPI environment against parallel file systems. -.PP -In each iteration of the test, each MPI task creates, stats, and removes -the specified number of directories and/or files and measures the performance -in ops/second.
