Allow key/value annotations to be added with the backup command and added/modified/removed with the new annotate command.
Annotations can be viewed with the info command in text mode when --set is specified and are always included in JSON output.
There are performance benefits to increasing the upload chunk size as long as the tradeoff with additional memory consumption is acceptable.
Make the chunk size configurable for S3, GCS, and Azure, but don't attempt to do any validation of the chunk size beyond some sane limits. The defaults remain as is for each storage type to avoid any unintentional regressions.
These limits can cause errors in some environments, e.g. Docker in Docker on Mac M1.
Entirely remove limits from the build, s3, and azure hosts since memory usage on these hosts is out of our control and not useful for testing.
Also allow empty variables to be rendered as blank.
Catching individual fatal errors was only used in testing so the tests have been updated to use other errors instead. CATCH_FATAL() is now the only way to catch fatal errors.
This simplifies the logic a bit for upcoming changes to error handling and cleanup.
Also fix an issue where passing errorMessage() directly to THROW*() would attempt to copy the message buffer instead of preserving it, which is undefined behavior. Since there were no instances of this behavior before this commit, this was not a live bug.
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).
The standby timeline check was being performed using pg_control data loaded before the backup started. If the backup was started immediately after a promotion the standby might not have executed a checkpoint and written the new timeline to pg_control.
Instead perform the timeline check after the checkpoint is executed. This should ensure that the new timeline is in pg_control.
The prior warning made it sound as if some action was required on the part of the user.
The new message should make it clearer that this action will be performed by pgBackRest.
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/
Add tzdata package so timezone tests in command/restore work correctly.
Mark default git path as safe. This is a security fix that is not applicable in this environment, but must be set.
Also remove package cleanup, which is inconvenient when new packages need to be installed. It makes sense for containers that will be downloaded from Dockerhub but not so much for a locally-maintained container.
This was clearly an attempt to set the mode when creating a directory, but it never worked and instead created a "750" directory in the current working directory.
Detected when running in an environment where the current working directory was read-only.
Add harness depends when present.
Include libyaml in all test builds.
Fix mode on paths before trying to remove and set test path with mode 770 to match the Perl test harness.
With these changes all unit tests run except those that specify the define (e.g. common/assert-off), binReq (e.g. command/archive-get), or containerReq (e.g. protocol/protocol) keywords.
Builds and code generation need to be done in advance. The following commands are required for setup:
meson setup -Dwerror=true -Dfatal-errors=true -Dbuildtype=debug build pgbackrest
ninja -C build test/src/test-pgbackrest
build/src/build-code help pgbackrest
build/src/build-code postgres pgbackrest
Now tests can be run, e.g.:
build/test/src/test-pgbackrest --module=postgres/interface
Creating new binaries was convenient at first but has now become a maintenance issue.
Solve this by combining that into a single binary that takes an additional parameter to indicate which code should be built.
Also clean up path handling to make it easier to build code from the command line.
This makes the test code a bit simpler where we are listing a path but not following links.
Links in the repository can be used for testing but should never be committed to the main branch.
NOTE TO PACKAGERS: An experimental meson build has been added but packagers should continue to use the autoconf/make build for the foreseeable future.

Explicitly set target timeline to "current" when type=immediate and PostgreSQL >= 12. We do this because type=immediate means there won't be any actual attempt to change timelines, but if we leave the target timeline as the default of "latest" then PostgreSQL might fail to restore because it can't reach the "latest" timeline in the repository from this backup.
This is really a PostgreSQL bug and will hopefully be addressed there, but we'll handle it here for older versions, at least until they aren't really seen in the wild any longer.
PostgreSQL < 12 defaults to "current" (but does not accept "current" as a parameter) so no need set it explicitly.
Previously a callback was used to list path contents and if no sort was specified then a snapshot was not required. When deleting files from the path some filesystems could omit files that still existed, which meant the path could not be removed.
Filter . out of lists in the Posix driver since this special entry was only used by test code (and filtered everywhere in the core code).
Also remove callbacks from the storage interface and replace with an iterator that should be easier to use and guarantees efficient use of the snapshots.
v0.45 ships with Ubuntu 18.04, which is currently the oldest distro we support. We may never do a Meson release on Ubuntu 18.04 but this allows us to start running unit tests with Meson in the meantime.
Some more granular options are not available so we use buildtype in more places.
The check for a in-tree autoconf/make build had to be removed since the filesystem APIs are not available.
Finally, alias_target was removed. This means that full paths must be used for build targets, which does not seem too bad. For instance, test/src/test-pgbackrest must now be used as a build target instead of simple test-pgbackrest.
Coverage for these checks was dependent on the order the files were read from disk, which made the tests fragile.
Rearrange the checks and add a test that won't depend on order.
Previously we were just checking for the existence of NextContinuationToken, which the S3 documentation indicates will not be present when the list is not truncated. However, recent versions of Scality send a blank NextContinuationToken when IsTruncated is false. Sending the blank continuation token back causes Scality to send another blank continuation token and an infinite loop occurs.
Instead use IsTruncated (which is required to be present) to determine whether NextContinuationToken should be present. Error if NextContinuationToken is then missing or empty, since an empty token caused an infinite loop with the Scality server (which arguably should have errored when passed an empty token).
The TEST_STORAGE_LIST() macro is more robust and hides the callback mechanism from the caller.
Add features to TEST_STORAGE_LIST() that hrnStorageInfoListCallback() had.
Update tests to use the abbreviated type output (e.g. path/) generated by TEST_STORAGE_LIST().
This provides reproducible builds and minimizes the file path in debug messages, just like an in-tree make build.
For test source, prefix with test/ in case there are any module name collisions.
Having the test harness in C will allow us to remove duplicated Perl code and test on systems where Perl support is not present.
Custom harnesses and shims are currently not implemented, which means only the following tests in the common module will run: error, stack-trace, type-convert, assert-on, mem-context, time, encode, type-object, type-string, type-list, type-buffer, type-variant, reg-exp, log.
The experimental test harness is being committed with partial functionality so it can be used in Windows development. The remaining features will follow as needed.
The meson builds are still experimental so for now the configure/make build process is preferred for release builds. This message should help prevent any automated build systems from picking up meson instead.
Some of the replacements that were being done already existed as constants, so use the constants instead.
Also fix a minor formatting error introduced when testAdd() was renamed to hrnAdd().
This module has dependencies on command/command so it does not make sense for it to be in the common module. Also move protocolFree() to main() since this is a very large dependency.
Adjust the tests so command/exit can be tested later. This is a bit messy but will get adjusted as we improve the test harness.
