This parameter is now optional and defaults to none so there is no reason to explicitly show it in user-facing documentation.
Also make the vm parameter in ci.pl optional to be consistent with how test.pl behaves.
Ubuntu 18.04 will be EOL before the next release, so update to the oldest available Debian version.
Also fix one incorrect return value type, a test cast, and adjust some test timeouts.
The code is not completely reflowed yet so there are some cases that uncrustify will not catch. The formatting will be improved over time.
Some block of code require special formatting so have been surrounded with the {uncrustify-off}/{uncrustify-on} markers. These exceptions should be kept to a minimum.
Add --code-format (to reformat code) and --code-format-check (to check formatting) to test.pl.
Add a CI test that will check code formatting. Code must be correctly formatted before it can be merge to integration.
Add documentation to the coding standards for code formatting.
Running valgrind and backtrace together has been causing tests to timeout in CI, mostly likely due to limited resources. This has not been a problem in normal development environments.
Since it is still important to run backtraces for debugging, split the u22 test that was doing all this work to run coverage and backtrace together and valgrind-only as a separate test. As a bonus these tests run faster separately and since they run in parallel the total execution time is faster.
The libbacktrace feature has not been working since the move to meson because libbacktrace detection was not added to the meson build. Add libbacktrace to meson and improve the feature so that it can be compiled into release builds.
The prior implementation fetched line numbers with each stack trace push. Not only was this slow but it missed any functions that were not being tracked on our stack.
Instead just examine the backtrace when an error happens and merge it with the info we have on our stack. If the backtrace is not available then the output remains as before.
Also remove --backtrace from test.pl since the library is now auto-detected.
Leave this library out of the production build for now to give it a little time to shake out in testing.
This should make it a little clearer what the variable (VR) macros are doing since the declaration/definition cannot both be set to extern (but functions can).
Splitting the variable macros out also allows them to be changed in the future with little churn, while changing the function macro creates a large amount of churn.
This is immediately useful because it will detect any extern'd functions or variables that are not being used. It also detects functions or variables that are declared but not defined.
If a FV/VR_EXTERN macro is missing it will be detected either because of a mismatch in the declaration/definition or because a new defined symbol will appear in the nm test.
Eventually the unity build will be used to create a more optimized pgbackrest binary but that will need to wait.
All unit and performance tests are now built by the C harness.
Remove all unit/performance test build code from Perl.
Remove code from C harness that is no longer used. This code was included so the C harness could be run separately, but that is no longer needed with this full integration.
The C test harness is used for unit tests from the Perl harness where possible. Currently, unit tests can be run in the C harness when --no-coverage is specified and --profile is not specified.
C harness tests work on meson 0.45.
The C harness runs with valgrind by default. Valgrind can be disabled with --no-valgrind.
Also rebuild containers to add meson and update the documentation so that meson builds will work (even though we don't do them yet).
Build pgbackrest binary and auto-generated code automatically.
Remove --module option and allow modules to run by parameter. This is less verbose and multiple modules can be run at a time.
Allow filtering of modules. Multiple tests can be passed as parameters and if the module ends in / it will be used as a prefix filter. For example, common/ will run all the common modules.
If a test errors the remaining tests will still run but the test process will eventually exit with an error.
CI tests are included but unit tests remain on the development branch.
With these changes all unit tests run except those that specify the define (e.g. common/assert-off) or containerReq (e.g. protocol/protocol) keywords.
Building the C test harness has been simplified:
meson -Dwerror=true -Dfatal-errors=true -Dbuildtype=debug test/build/none pgbackrest
ninja -C test/build/none test/src/test-pgbackrest
To run all modules:
test/build/none/test/src/test-pgbackrest test
Just the common/error module:
test/build/none/test/src/test-pgbackrest test common/error
All info modules:
test/build/none/test/src/test-pgbackrest test info/
Both have newer gcc and OpenSSL 3.
Fedora 36 runs horribly slow with valgrind enabled so run the valgrind tests on Ubuntu 22.04. Fedora 36 has a newer gcc so it is still worth testing on.
Maintaining the version interfaces was complicated by the fact that each interface needed to be in separate compilation unit to avoid type conflicts. This also meant that various build/test files needed to be updated to add the new interfaces.
Solve these problems by auto-generating all the interfaces into a single file. This is made possible by parsing defines and types out of the header files and creating macros to rename the types. At the end of the version interface everything is undef'd. Another benefit is that the auto-generated interfaces can be static and included directly into postgres/interface.c.
Since some code generation is now always required for tests, change --no-gen to --min-gen in test.pl.
It would also make sense to auto-generate the version defines in postgres/version.h, but that will be left for a future commit.
Meson is a new build system that offers simpler syntax and superior performance to autoconf/make. In addition, Windows is supported natively.
The Meson build appears complete, but currently is used only for auto-generation of code and the host build of pgbackrest. Some container upgrades will be required before Meson can be used for container builds.
Also patch the Debian package to force autoconf/make rather than Meson.
This helps rebalance some of the tests that are running long, i.e. d9 and u20.
I would be better to move more PostgreSQL versions to d9, but the base VM does not contain more versions. New minor versions will be out later in the week so that seems a better time to be rebuilding containers.
The emulation is so slow that running all the unit tests would be too expensive, but this at least shows that the build works and some of the more complex tests run. In particular, it is good to test on one big-endian architecture to be sure that checksums are correct.
Update checksums in the tests where they had gotten out of date since the last time we were testing on s390x. Also use a different test in command/archivePushTest to show the name of the file when a checksum does not match to aid in debugging.
The command/archive-push test was updated but not included because there is also a permissions issue, which looks to be the same as what we see on MacOS/FreedBSD. Hopefully we'll be able to fix all of those at the same time.
It also makes sense to lock old PRs. They can be manually unlocked if they are needed for some reason.
Also add output logging to make it easier to determine if thread locking is completing.
The old plugin has been defunct for some time so there are currently a lot of unlocked issues.
Running this once per week seems sufficient for now. Worst case it can be run manually if it gets behind.
Since CentOS 8 will be EOL at the end of the year it makes sense to do this now. The centos:8 image is still used in documentation.xml because changes there require manual testing, which will need to be done at a later date. The changes are not user-facing, however, and can be done at any time.
Also update CentOS references to RHEL since that is what we are emulating for testing purposes.
Parse enough of config.yaml to auto-generate config.auto.h and config.auto.c.
This commit implements most of the infrastructure needed to migrate the rest of the build code to C, but each set of auto-generated files will present its own challenges.
The build is now dependent on libyaml. At this point there is no need for a hard requirement, but that will come soon so it seems better to add the dependency now.
Update Ubuntu 12.04 to 16.04. Version 16.04 is recently EOL but testing on an old version is beneficial.
Update Ubuntu 18.04 to 20.04.
Update Fedora 32 to 33. Version 34 would have been preferred but there were some build issues, i.e. the default shell did not work with configure, and after ksh was installed configure locked up.
Add --no-install-recommends to apt-get commands to save a bit of time and space.
Update test Dockerfile to run in multiple steps. This makes the container larger but also makes rebuilding after changes faster. The --squash option may be used to keep the container small.
Remove obsolete casts in protocol/parallel module. These casts were included in the original migration because Ubuntu 12.04 32-bit gcc required them, but Ubuntu 16.04 32-bit gcc complains. There is no production issue here since at this point in the code the file descriptors are guaranteed to be >= 0.
The CentOS 7 documentation test relies on PostgreSQL 9.5 which has been removed from the yum.p.o repository package. Switch the test to CentOS 8 to fix the immediate issue, but a decision on the PostgreSQL 9.5 documentation will need to be made before the next release.
Testing on Travis-CI has been getting slower (from ~18 minutes to 3-6 hours) and the travis-ci.org service will be terminated at the end of the year. Moving to travis-ci.com is an option but the quotas are too low for our purposes.
Instead use Github Actions, which does not currently have quotas, and runs our current tests with just a few tweaks.
This still leaves multi-architecture tests on Travis-CI but we may be able to run those and stay within the new quotas.
Also fix a minor bug in restoreTest.c exposed by Github Actions using a different name for the user and group.
