There are many ways to +contribute, and we appreciate all of them. If you have questions, please feel +free to ask on [GitHub](https://github.com/speedb-io/speedb/discussions). + +Please read and follow our [Code of Conduct](CODE_OF_CONDUCT.md) to keep our +community welcoming, helpful, and respectable. + +## Ways to contribute + +There are several ways to contribure to Speedb, the most obvious of which is by +contributing code changes, but it's not the only one. + +### Help document Speedb + +We strive to provide an extensive and up to date documentation of Speedb, so if +you find an area where the documentation is lacking, we would love to have you +contribute changes to address that. + +### Help address bugs + +We'll inevitably have bugs, or other kinds of issues. Helping us by reporting +such issues with detailed information (ideally with a test case attached), or +even simply analyzing and reproducing an existing issue, is a great way to get +involved. We track bugs and other kinds of issues using +[GitHub issues](https://github.com/speedb-io/speedb/issues). + +Please go over existing issues before opening a new one to avoid duplicates, and +please follow the relevant template when opening new issues. + +### Help contribute ideas + +If you have an idea for Speedb, we encourage you to +[discuss](https://github.com/speedb-io/speedb/discussions) it with the +community, and potentially prepare a proposal for it and submit it as a feature +request using the +[feature request template](https://github.com/speedb-io/speedb/issues/new?assignees=&labels=&template=feature_request.md&title=). + +If you do start working on a proposal, keep in mind that this requires a time +investment to discuss the idea with the community, get it reviewed, and +eventually implemented. We encourage discussing the idea early, before even +writing a proposal. + +### Help land changes + +If you find a feature request that you'd like to get into Speedb and there's a +pull request open for it, you can help by testing it and providing feedback. +When giving feedback, please keep comments positive and constructive. + +## How to become a contributor + +### Contribution guidelines and standards + +All documents and pull requests must be consistent with the guidelines and +follow the Speedb documentation and coding styles. + +- For **both** documentation and code: + + - When the Speedb team accepts new documentation or features, we take on + the maintenance burden. This means we'll weigh the benefit of each + contribution against the cost of maintaining it. + - The appropriate [style](#style) is applied. + - The [license](#license) is present in all contributions. + - Code review is used to improve the correctness, clarity, and consistency + of all contributions. + +- For documentation: + + - All documentation is written for clarity and readability. Beyond fixing + spelling and grammar, this also means content is worded to be accessible + to a broad audience. + - Typos or other minor fixes that don't change the meaning of a document + do not need formal review, and are often handled directly as a pull + request. + +- For code: + + - New features and substantive changes to Speedb need to go through a + formal feature request process. Pull requests are only sent after a + proposal has been discussed, submitted, and reviewed. + - Bug fixes and mechanical improvements don't need this. + - All new features and bug fixes include unit tests, as they help to (a) + document and validate concrete usage of a feature and its edge cases, + and (b) guard against future breaking changes to lower the maintenance + cost. + - Unit tests must pass with the changes. + - If some tests fail for unrelated reasons, we wait until they're fixed. + It helps to contribute a fix! + - Code changes should be made with API compatibility and evolvability in + mind. + +## Style + +### Source code + +Speedb follows the +[Google C++ Style](https://google.github.io/styleguide/cppguide.html). + +For formatting, we limit each line to 80 characters. Most formatting can be done +automatically by running + +``` +build_tools/format-diff.sh +``` + +or simply `make format` if you use GNU make. If you lack any of the dependencies +to run it, the script will print out instructions for you to install them. + +### Markdown files + +Markdown files should use [Prettier](https://prettier.io/) for formatting. + +## License + +A license is required at the top of all documents and files. + +### Source files + +Every new source file should have the following header at the top: + +``` +Copyright (C) Speedb Ltd.

After a reviewer approves the pull +request, a Speedb team member will merge it. + +### Fork and build + +[Fork](https://github.com/speedb-io/speedb/fork) the Speedb repository to your +own account and clone the resulting repository to your machine. + +Refer to the [README](README.md) and [INSTALL](INSTALL.md) documents for +information about how to build Speedb locally. + +### Checkout a pull request + +If you'd like to contribute by testing a pull request and providing feedback, +this section is for you. Otherwise, if you'd like to contribute by making +changes (to code or documentation), skip this section and read the next one +instead. + +Every pull request has its own number. This number is visible both in the URL +of a pull request page as well as in the title of the pull request page itself +(in the form #123, where 123 is the PR number). Follow +[this guide](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/reviewing-changes-in-pull-requests/checking-out-pull-requests-locally) +in order to checkout the pull request locally (if you're using GitHub CLI, be +sure to choose the GitHub CLI option rather than Web Browser on the guide page). +After you have the pull request changes checked out locally, you can move on to +testing the changes by using the information in the "Run the tests" section +below. + +### Make your changes + +This is where you update the documentation, fix a bug, test another +contributor's fix, or add a feature. Make sure your changes adhere to the +guidelines. + +If you add a new source file, be sure to add it to the `LIB_SOURCES` variable in +[`src.mk`](src.mk) (note the backslashes at the end of each line) as well as to +the `SOURCES` variable in [`CMakeLists.txt`](CMakeLists.txt). + +#### Update HISTORY.md + +For code-related changes, add a short description of your change to the +[HISTORY](HISTORY.md) document, especially if it's a bug fix, public API change +or an awesome new feature. + +#### Add a test + +If you make a code-related change, be sure to add a unit test. Speedb uses +[GTest](https://github.com/google/googletest) for the C++ unit tests and +[JUnit](https://junit.org/) for the Java unit tests. + +For the C++ unit test, prefer adding a test to an existing unit tests suite (in +the files ending with `_test.cc`) in order to keep build and test time at bay. +However, if this is a test for a new feature and it doesn't belong in any of the +existing test suites, you may add a new file. Be sure to update the +`TEST_MAIN_SOURCES` variable in [`src.mk`](src.mk) (note the backslashes at the +end of each line) as well as the `TESTS` variable in +[`CMakeLists.txt`](CMakeLists.txt). + +### Run the tests + +This is only needed for code-related changes, so if you only made changes to +documentation you can safely skip this section. + +#### C++ unit tests + +You can run the C++ unit tests using the Makefile as explained below, or, if +you're using CMake, using `ctest`. The Makefile has support for running the unit +tests in parallel using GNU Parallel, so it's recommended that you install it +first using your system's package manager (refer to the GNU Parallel +[official webpage](https://www.gnu.org/software/parallel/) for more +information). + +In order to run unit tests execute the following command: + +``` +make check +``` + +This will build Speedb and run the tests. You can provide the `-j` flag to +`make` in order to make a better utilization of CPU and speed up the build. Note +that this flag only affects the build, not the tests themselves. If you have GNU +Parallel installed, you can control the number parallel tests to run using the +environment variable `J`. For example, to build on a 64-core CPU and run the +tests in parallel, you can run: + +``` +make J=64 check -j64 +``` + +Unlike `-j`, which if not provided defaults to 1, if `J` isn't provided, the +default is to run one job per core. + +If you switch between release and debug build, normal or lite build, or compiler +or compiler options, call `make clean` first. So here is a safe routine to run +all tests: + +``` +make clean && make check -j64 +``` + +#### Debugging single unit test failures + +You can run a specific unit test by running the test binary that contains it. If +you use GNU make, the test binary will be located in the root directory of the +repository (if you use CMake, the test binary will be in your build directory). +For example, the test `DBBasicTest.OpenWhenOpen` is in the binary +`db_basic_test`, so simply running + +``` +./db_basic_test +``` + +will run all tests in the binary. + +GTest provides some useful command line parameters, and you can see them by +providing the `--help` argument to the test binary: + +``` +./db_basic_test --help +``` + +The flag you're most likely to use is probably `--gtest_filter`, which allows +you to specify a subset of the tests to run. For example, if you only want to +run `DBBasicTest.OpenWhenOpen`: + +``` +./db_basic_test --gtest_filter="*DBBasicTest.OpenWhenOpen*" +``` + +By default, the test DB created by tests is cleared up even if the test fails. +You can preserve it by using `--gtest_throw_on_failure`. If you want to stop the +debugger when an assertion fails, specify `--gtest_break_on_failure`. + +The `KEEP_DB=1` environment variable is another way to preserve the test DB from +being deleted at the end of a unit-test run, regardless of whether the test +fails or not: + +``` +KEEP_DB=1 ./db_basic_test --gtest_filter=DBBasicTest.Open +``` + +By default, the temporary test files will be under `/tmp/rocksdbtest-/` +(except when running in parallel, in which case they are under `/dev/shm`). You +can override the location by using the `TEST_TMPDIR` environment variable.

If crash test +doesn't cover the new feature, add it there. + +To run all crash tests, run + +``` +make crash_test -j64 +make crash_test_with_atomic_flush -j64 +``` + +If you are unable to use GNU make, you can manually build the `db_stress` +binary, and run the following commands manually: + +``` + python -u tools/db_crashtest.py whitebox + python -u tools/db_crashtest.py blackbox + python -u tools/db_crashtest.py --simple whitebox + python -u tools/db_crashtest.py --simple blackbox + python -u tools/db_crashtest.py --cf_consistency blackbox + python -u tools/db_crashtest.py --cf_consistency whitebox +``` + +#### Performance tests + +For changes that might impact performance, we suggest normal benchmarks are run +to make sure there is no regression (see [benchmark.sh](tools/benchmark.sh)). +Depending the actual performance, you may choose to run against a database +backed by disks, or memory-backed file systems. + +### Commit changes + +Please keep your commits: + +- Standalone - The code must compile and run successfully after each commit + (no breaking commits!). +- Minimal - Break your code into minimal, logically-complete chunks. +- Self-Reviewed - Always double-check yourself before submitting. + +Commit messages should: + +- Start with a component name followed by a colon. For example, if you made + changes to the documentation, prefix the commit message with `docs: `. If + you only updated tests, prefix the commit message with `tests: `. For + build-related changed use `build: `, etc. +- Reference a relevant issue, if any. This is especially relevant for bug + fixes and new features. The issue should be referenced at the end of the + first line as a hash sign followed by the issue number. For example, `#23`. + If there's more than one issue that applies, mention the main one on the + first line, and add a reference to the rest at the end of the commit message + (e.g. `Also fixes #54, #89, and #99`). +- Have the line length limited to 100 characters or less.

By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Lesser General Public License instead.) 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 -this service 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 make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. 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. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. 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 works. But when you -distribute the same sections 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 of 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 of 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 or 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 will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of 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 - - 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 -convey 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 2 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, write to the Free Software Foundation, Inc., - 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this -when it starts in an interactive mode: - - Gnomovision version 69, Copyright (C) year name of author - Gnomovision 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, the commands you use may -be called something other than `show w' and `show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary. Here is a sample; alter the names: - - Yoyodyne, Inc., hereby disclaims all copyright interest in the program - `Gnomovision' (which makes passes at compilers) written by James Hacker. - - , 1 April 1989 - Ty Coon, President of Vice - -This General Public License does not permit incorporating your program into -proprietary programs.

The sequence number is being changed when modification happens in the db. This feature allows the db to take a snapshot without acquiring db mutex when the last snapshot has the same sequence number as a new one. In transactional db with mostly read operations, it should improve performance when used with multithreaded environment and as well other scenarios of taking large amount of snapshots with mostly read operations. +* Add a TablePinningPolicy to the BlockBasedTableOptions. This class controls when blocks should be pinned in memory for a block based table. The default behavior uses the MetadataCacheOptions to control pinning and behaves identical to the previous releases. +* Redo of Index/Filter/Data blocks sizes in Block (LRU) Block Cache per CF after rebase on RocksDB 8.1 . This was part of v2.3.0 and was broken due to changes made in RocksDB. This feature provides per CF information on the size of its Index / Filter / Data blocks in the block cache (only for LRUCache at the moment). The information is printed to the log and the kBlockCacheCfStats and kFastBlockCacheCfStats properties were added to support obtaining the information programmatically. + +### Enhancements +* db_bench: add estimate-table-readers-mem benchmark which prints these stats. +* A new option on_thread_start_callback has been added.
