The option to specify the path to psql was shown in the command-line help as --psql-bin but the option was actually named --pgsql-bin.
Rename to match the help so they are consistent.
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).
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.
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.
These files were never intended to be compiled on their own so the .c extension was a bit misleading. In particular Meson does not like .c files that are not intended to be compiled independently.
Leave header files as is since they are already protected against being included more than once and are never expected to be compiled.
Remove VM_OS_REPO since it is no longer required.
Rebalance PostgreSQL versions for more efficient test times.
Always print version of PostgreSQL when testing. This helps verify that new minor releases are being used.
Integration expect log testing was originally used as a rough-and-ready way to make sure that certain code paths were being executed before the unit tests existed. Now that we have 100% unit test coverage (with expect log testing) the value of the integration expect tests seems minimal at best.
But they do cause numerous issues:
- Maintenance of the expect code and replacements that are required to keep logs reproducible.
- Even a trivial change can cause massive churn in the expect logs, e.g. d9088b2. These changes should be minutely audited but since the expect logs have little value now it is seldom worth the effort.
- The OS version used to do expect testing (RHEL7) can only be used to test one version of PostgreSQL. This makes it hard to balance the PostgreSQL version testing between OS versions.
- When a commit affects expect logs it is not clear (especially for new developers) how to regenerate them and our contributing guide is silent on the issue.
The goal is to migrate the integration tests to C and expect testing is not part of that plan. It seems best to get rid of them now.
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.
PostgreSQL 15 drops support for exclusive backup and renames the start/stop backup commands.
This is based on the pgdg-testing repo since beta1 has not been released yet, but it seems unlikely that breaking changes will be made at this point. beta1 should be tagged just before our next release so we'll retest before the release.
Only set -DDEBUG_MEM for the modules currently being tested rather than globally.
Also run tests in a temp mem context. Running in the top context can confuse memory accounting when a new context is created in the top context.
The unit tests were ignoring stderr but nothing being output there was important. Now a test will fail if there is anything on stderr.
This makes it easier to work with -fsanitize, which outputs to stderr.
The /etc/profile.d/lang.sh script was causing issues but it does not exist on amd64, so it seems the easiest thing was to remove it.
Fix how 32-bit VMs are determined now that another 64-bit architecture has been added.
And remove some obsolete VM hashes.
This flag was only being used by the backup command after manifestNewBuild() and had no other uses. There was a time when it was important for integration testing but the unit tests now fulfill this role.
Since backup is the only code concerned with the primary flag, move the code into the backup module.
We don't have any cross-version testing but this change was tested manually with the most recent version of pgBackRest to make sure it was tolerant of the missing primary info. When an older version of pgBackRest loads a newer manifest the primary flag will always be set to false, which is fine since it is not used.
There is no evidence that users need 8.3/8.4 anymore but it does cost us in terms of development and testing, especially now that we have a number of new backup/restore features planned.
It seems to make sense to remove this support now. If there are users who need to use/migrate from these versions they can use an older version of pgBackRest.
A CHECK() worked exactly like ASSERT() except that it was compiled into production code. However, over time many checks have been added that should not throw AssertError, which should be reserved for probable coding errors.
Allow the error code to be specified so other error types can be thrown. Also add a human-readable message since many of these could be seen by users even when there is no coding error.
Update coverage exceptions for CHECK() to match ASSERT() since all conditions will never be covered.
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.
This is mostly to revert some comment changes in b11ab9f7 that will break the ppc64le patch, but at the same time keep the spelling consistent in all comments and documentation.
Also revert some space changes for the same reason.
These flags are used for all tests but it was not possible to add them to configure before the change in 046d6643. This is especially important for adhoc tests to ensure the flags are not forgotten.
Remove the flags from test make commands where they were being applied.
There is no change for production builds.
The TLS server is an alternative to using SSH for protocol connections to remote hosts.
This command is currently experimental and intended only for trial and testing. As such, the new commands and options will not show up in the command-line help unless directly requested.
Some tests can generate very large error messages for diffs and they often get cut off before the end.
Also fix a test so it does not create too large a buffer on the stack.
The newer version of valgrind helps with some arm64 issues that have been fixed since the architecture has become more popular. Also add the valgrind builds to the Vagrantfile and Dockerfile.
Move the CA cert install from the base container to the test container. This means the CA cert can be changed without rebuilding all the base containers.
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.
There are no code changes from PostgreSQL 13 so simply add the new version.
Add CATALOG_VERSION_NO_MAX to allow the catalog version to "float" during the PostgreSQL beta/rc period so new pgBackRest versions are not required when the catalog version changes.
Update the integration tests to handle new PostgreSQL startup messages.
A define was already added for TEST_PATH but it was not widely used. Replace all occurrences of testPath() with TEST_PATH in the tests.
Replace testUser() with TEST_USER, testGroup() with TEST_GROUP, testRepoPath() with HRN_PATH_REPO, testDataPath() with HRN_PATH, testProjectExe() with TEST_PROJECT_EXE, and testScale() with TEST_SCALE.
Replace {[path]}, {[user]}, {[group]}, etc. with defines and remove hrnReplaceKey(). This is better than having two ways to deal with replacements.
In some cases the original test*() getters were kept because they are used by the harness, which does not have access to the new defines. Move them to harnessTest.intern.h to indicate that the tests should no longer use them.
A shim allows a test harness to access static functions and variables in a C module, and also allows functions to be shimmed (i.e. overridden) for the purposes of testing.
For instance, coverage testing works when a process that is normally exec'd is run as a forked child process instead.
Some version interface test functions were integrated into the core code because they relied on the PostgreSQL versioned interface. Even though they were compiled out for production builds they cluttered the core code and made it harder to determine what was required by core.
Create a PostgreSQL version interface in a test harness to contain these functions. This does require some duplication but the cleaner core code seems a good tradeoff. It is possible for some of this code to be auto-generated but since it is only updated once per year the matter is not pressing.
The tests worked fine on multiple architectures, but would only run "bare metal", i.e. tests that required containers could not be run.
Enable basic multi-architecture support by allowing containers to be built using whatever architecture the host supports. Also allow cached containers to be defined for multiple architectures in container.yaml.
Add a Dockerfile which can be used as a container for other containers to provide a consistent development environment.
The primary goal is to allow development on Mac M1 but other architectures should find these improvements useful.
