These results were stored in the vagrant path along with a full copy of src.
Instead store the raw coverage data in test/result/raw and change source references to the files that already exist in [test-path]/repo.
It makes more sense to build in the test path since many developers won't have a vagrant path. Anyway, it's better not to modify the vagrant path since it belongs to vagrant.
Instead of installing the binary just mount it into the container from where it was built. This saves a bit of time and space.
The prior method was to build a special container to hold these files which meant they would get stale on development systems. On CI the container was always rebuilt so failures would be seen there even when dev seemed to be working.
Instead get the package source when the package is built to ensure it is as up-to-date as possible.
This change was prompted by failures on the Ubuntu 12.04 container while getting the package source, probably due to an ancient version of git. Package builds are no longer supported on that platform with the addition of lz4 compression so it didn't seem worth fixing.
The primary source for project info is now src/version.h.
The pgBackRestDoc::ProjectInfo module loads the project info from src/version.h at runtime so there is no need to update it.
This is consistent with the way BackRest and BackRest test were renamed way back in 18fd2523.
More modules will be moving to pgBackRestDoc soon so renaming now reduces churn later.
This directory was once the home of the production Perl code but since f0ef73db this is no longer true.
Move the modules to test in most cases, except where the module is expected to be useful for the doc engine beyond the expected lifetime of the Perl test code (about a year if all goes well).
The exception is pgBackRest::Version which requires more work to migrate since it is used to track pgBackRest versions.
LZ4 compresses data faster than gzip but at a lower ratio. This can be a good tradeoff in certain scenarios.
Note that setting compress-type=lz4 will make new backups and archive incompatible (unrestorable) with prior versions of pgBackRest.
This was the interface between Perl and C introduced in 36a5349b but since f0ef73db has only been used by the Perl integration tests. This is expensive code to maintain just for testing.
The main dependency was the interface to storage, no matter where it was located, e.g. S3. Replace this with the new-introduced repo commands (d3c83453) that allow access to repo storage via the command line.
The other dependency was on various cfgOption* functions and CFGOPT_ constants that were convenient but not necessary. Replace these with hard-coded strings in most places and create new constants for commonly used values.
Remove all auto-generated Perl code. This means that the error list will no longer be maintained automatically so copy used errors to Common::Exception.pm. This file will need to be maintained manually going forward but there is not likely to be much churn as the Perl integration tests are being retired.
Update test.pl and related code to remove LibC builds.
Ding, dong, LibC is dead.
Add compress-type option and deprecate compress option. Since the compress option is boolean it won't work with multiple compression types. Add logic to cfgLoadUpdateOption() to update compress-type if it is not set directly. The compress option should no longer be referenced outside the cfgLoadUpdateOption() function.
Add common/compress/helper module to contain interface functions that work with multiple compression types. Code outside this module should no longer call specific compression drivers, though it may be OK to reference a specific compression type using the new interface (e.g., saving backup history files in gz format).
Unit tests only test compression using the gz format because other formats may not be available in all builds. It is the job of integration tests to exercise all compression types.
Additional compression types will be added in future commits.
All the methods in this module will need to be implemented via the command-line in order to get rid of LibC, so the first step is to reduce the code in the module as much as possible.
First remove storageDb() and use storageTest() instead. Then create storageTest() using pgBackRestTest::Common::Storage which has no dependencies on LibC. Now the only storage using the LibC interface is storageRepo().
Remove all link functions since those operations cannot be performed on a repo unless it is Posix, in which case the LibC interface is not needed. Same for owner().
Remove pathSync() because syncs are not required in the tests. No test data is reused after a crash.
Path create/exists functions should never be explicitly performed on a repo so remove those. File exists can be implemented by calling info() instead.
Remove encryption detection functions which were only used by Backup/Archive::Info reconstruct() which are now obsolete.
Remove all filters except pgBackRest::Storage::Filter::CipherBlock since they are not being used. That also means there are no filters returning results so remove all the result code.
Move hashSize() and pathAbsolute() into pgBackRest::Storage::Base where they can be shared between pgBackRest::Storage::Storage and pgBackRestTest::Common::Storage.
This was mostly dead code except the DB_BACKUP_ADVISORY_LOCK constant, moved to the real/all test module, and the function that pulls info from pg_control, moved to ExpireEnvTest.pm.
Using static values serves as a better cross-check against the page checksum code. The downside is that these checksums may not work with some big endian systems but in that case neither will the unit tests.
We can also remove the page checksum interface from LibC which brings us one step closer to eliminating it.
Page size is passed around a lot but in fact it can only have one value, PG_PAGE_SIZE_DEFAULT, which is checked when pg_control is loaded. There may be an argument for supporting multiple page sizes in the future but for now just use the constant to simplify the code.
There is also a significant performance benefit. Because pageSize was being used in pageChecksumBlock() the main loop was neither unrolled nor vectorized (-funroll-loops -ftree-vectorize) as it is now with a constant loop boundary.
The restore test function was passing strBackup to the restoreCompare function but when the restore is expected to pick a backup based on a timestamp, then strBackup may not be the one chosen.
Modified the code so that strBackupExpected is set based on the parameters passed to the function and this is then passed to restoreCompare.
The main improvement is a double-fork to prevent zombie processes if the parent process exits after the (child) async process. This is a real possibility since the parent process sticks around to monitor the results of the async process.
In the first fork, ignore SIGCHLD in the very unlikely case that the async process exits before the first fork. This is probably only possible if the async process exits immediately, perhaps due to a chdir() failure. Set SIGCHLD back to default in the async process so waitpid() will work as expected.
Also update the comment on chdir() to more accurately reflect what is happening.
Finally, add a test in certain debug builds to ensure the first fork exits very quickly. This only works when valgrind is not in use because valgrind makes forking so slow that it is hard to tell if the async process performed work or not (in the case that the second fork goes missing and the async process is a direct child).
Auto-selection is performed only when --set is not specified. If a backup set for the given target time cannot not be found, the latest (default) backup set will be used.
Currently a limited number of date formats are recognized and timezone names are not allowed, only timezone offsets.
pkg-config is a generic way to get build options rather than relying on a package-specific utility.
XML2_CONFIG can be used to override this utility for systems that do not ship pkg-config.
Most of these tests are just checking that errors are thrown when required. These are well covered in various unit tests.
The "cannot resume" tests are also well covered in the backup unit tests.
Finally, config warnings are well covered in the config unit tests.
There is more to be done here, but this accounts for the low-hanging fruit.
Set log-level-file=off when more that one test will run. In this case is it impossible to see the logs anyway since they will be automatically cleaned up after the test. This improves performance pretty dramatically since trace-level logging is expensive. If a singe integration test is run then log-level-file is trace by default but can be changed with the --log-level-test-file option.
Reduce buffer-size to 64k to save memory during testing and allow more processes to run in parallel.
Update log replacement rules so that these options can change without affecting expect logs.
Remove embedded Perl from the distributed binary. This includes code, configure, Makefile, and packages. The distributed binary is now pure C.
Remove storagePathEnforceSet() from the C Storage object which allowed Perl to write outside of the storage base directory. Update mock/all and real/all integration tests to use storageLocal() where they were violating this rule.
Remove "c" option that allowed the remote to tell if it was being called from C or Perl.
Code to convert options to JSON for passing to Perl (perl/config.c) has been moved to LibC since it is still required for Perl integration tests.
Update build and installation instructions in the user guide.
Remove all Perl unit tests.
Remove obsolete Perl code. In particular this included all the Perl protocol code which required modifications to the Perl storage, manifest, and db objects that are still required for integration testing but only run locally. Any remaining Perl code is required for testing, documentation, or code generation.
Rename perlReq to binReq in define.yaml to indicate that the binary is required for a test. This had been the actual meaning for quite some time but the key was never renamed.
For the most part this is a direct migration of the Perl code into C except as noted below.
A backup can now be initiated from a linked directory. The link will not be stored in the manifest or recreated on restore. If a link or directory does not already exist in the restore location then a directory will be created.
The logic for creating backup labels has been improved and it should no longer be possible to get a backup label earlier than the latest backup even with timezone changes or clock skew. This has never been an issue in the field that we know of, but we found it in testing.
For online backups all times are fetched from the PostgreSQL primary host (before only copy start was). This doesn't affect backup integrity but it does prevent clock skew between hosts affecting backup duration reporting.
Archive copy now works as expected when the archive and backup have different compression settings, i.e. when one is compressed and the other is not. This was a long-standing bug in the Perl code.
Resume will now work even if hardlink settings have been changed.

The TZ environment variable was not reliably pushed down to the test processes.
Instead pass TZ via a command line parameter and set explicitly in the test process.
82df7e6f and 9856fef5 updated tests that used test points in preparation for the feature not being available in the C code.
Since tests points are no longer used remove the infrastructure.
Also remove one stray --test option in mock/all that was essentially a noop but no longer works now that the option has been removed.
These were not getting updated to match the directory name when the manifests were copied.
The Perl code didn't care but the C code expects labels to be set correctly.
Archive check does not run when in offline backup mode but the option was set to true in the manifest. It's harmless since these options are informational only but it could cause confusion when debugging.
Test points are not supported by the new C code so these will be replaced with unit tests.
The fact that the tests still pass even when the changes aren't made mid-backup (except application_name) shows how weak they were in the first place.
Even so, this does represent a regression in (soon to be be removed) Perl coverage.
Test points will not be available in the C code so update these tests as best as possible without using them.
This represents a loss of coverage for the Perl code (soon to be removed) which will be made up in the C code with unit tests.
These tests require test points which are not being implemented in the C code.
This functionality is fully tested in the command/control unit tests so integration tests are no longer required.
This expression determines which files contain page checksums but it was also including the directory above the relation directories. In a real PostgreSQL installation this not a problem because these directories don't contain any files.
However, our tests place a file in `base` which the Perl code thought should have page checksums while the new C code says no.
Update the expression to document the change and avoid churn in the expect logs later.
Installing lcov 1.14 everywhere turned out to be a problem just as using 1.13 on Ubuntu 19.04 was.
Since we primarily use Ubuntu 18.04 for coverage testing and reporting, we definitely want to make sure that works. So, revert to using the default packaged lcov except when specified otherwise in VmTest.pm.
PostgreSQL minor version releases are also included since all containers have been rebuilt.
The protocol timeout tests have been superceded by unit tests.
The TEST_BACKUP_RESUME test point was incorrectly included into a number of tests, probably a copy pasto. It didn't hurt anything but it did add 200ms to each test where it appeared.
Catalog and control version tests were redundant. The database version and system id tests covered the important code paths and the C code gets these values from a lookup table.
Finally, fix an incomplete update to the backup.info file while munging for tests.

We had some problems with newer versions so had held off on updating. Those problems appear to have been resolved.
In addition, the --compat flag is no longer required. Prior versions of MinIO required all parts of a multi-part upload (except the last) to be of equal size. The --compat flag was introduced to restore the default S3 behavior. Now --compat is only required when ETag is being used for MD5 verification, which we don't do.
Previously the mock integration tests would be skipped for VMs other than the standard four used in CI. Now VMs outside the standard four will run the same tests as VM4 (currently U18).
1.13 is not compatible with gcc 8 which is what ships with newer distributions. Build from source to get a more recent version.
1.13 is not compatible with gcc 9 so we'll need to address that at a later date.
This user was created before we tested in containers to ensure isolation between the pg and repo hosts which were then just directories. The downside is that this resulted in a lot of sudos to set the pgbackrest user and to remove files which did not belong to the main test user.
Containers provide isolation without needing separate users so we can now safely remove the pgbackrest user. This allows us to remove most sudos, except where they are explicitly needed in tests.
While we're at it, remove the code that installed the Perl C library (which also required sudo) and simply add the build path to @INC instead.
This test was not creating recovery.signal when testing with --type=preserve. The preserve recovery type only keeps existing files and does not create any.
RC1 was just ignoring recovery.signal and going right into recovery. Weirdly, 12.0 used restore_command to do crash recovery which made the problem harder to diagnose, but this has now been fixed in PostgreSQL and should be released in 12.1.
A number of tests have been updated and Fedora 30 has been added to the test suite so the unit tests can run on gcc 9.
Stop running unit tests on co6/7 since we appear to have ample unit test coverage.
This tool was only being used it a few places but was a pretty large dependency.
Rework the forceStorageMove() code using our storage layer and replace one aws cli cp with a storage put.
Also, remove the Dockerfile that was once used to build the Scality S3 test container.
Now that our tests are more diversified it makes sense to load only the packages that are needed for each test.
Move the package loads from .travis.yaml to test/travis.pl where we have more control over what is loaded.
Note that building the manifest on each host has been temporarily removed.
This feature will likely be brought back as a non-default option (after the manifest code has been fully migrated to C) since it can be fairly expensive.
Three major changes were required to get this working:
1) Provide the path to pgbackrest in the build directory when running outside a container. Tests in a container will continue to install and run against /usr/bin/pgbackrest.
1) Set a per-test lock path so tests don't conflict on the default /tmp/pgbackrest path. Also set a per-test log-path while we are at it.
2) Use localhost instead of a custom host for TLS test connections. Tests in containers will continue to update /etc/hosts and use the custom host.
Add infrastructure and update harnessCfgLoad*() to get the correct exe and paths loaded for testing.
Since new tests are required to verify that running outside a container works, also rework the tests in Travis CI to provide coverage within a reasonable amount of time. Mainly, break up to doc tests by VM and run an abbreviated unit test suite on co6 and co7.
Recovery settings are now written into postgresql.auto.conf instead of recovery.conf. Existing recovery_target* settings will be commented out to help avoid conflicts.
A comment is added before recovery settings to identify them as written by pgBackRest since it is unclear how, in general, old settings will be removed.
recovery.signal and standby.signal are automatically created based on the recovery settings.
Scaling allows the starting values to be increased from the command-line without code changes.
Also suppress valgrind and assertions when running performance testing. Optimization is left at -O0 because we should not be depending on compiler optimizations to make our code performant, and it makes profiling more informative.
PostgreSQL 12 will shutdown in these cases which seems to be the correct action (according to the documentation) when hot_standby = off, but older versions are promoting instead. Set target_action explicitly so all versions will behave the same way.
This does beg the question of whether the PostgreSQL 12 behavior is wrong (though it matches the docs) or the previous versions are.
This restore type automatically adds standby_mode=on to recovery.conf.
This could be accomplished previously by setting --recovery-option=standby_mode=on but PostgreSQL 12 requires standby mode to be enabled by a special file named standby.signal.
The new restore type allows us to maintain a common interface between PostgreSQL versions.
For the most part this is a direct migration of the Perl code into C.
There is one important behavioral change with regard to how file permissions are handled. The Perl code tried to set ownership as it was in the manifest even when running as an unprivileged user. This usually just led to errors and frustration.
The C code works like this:
If a restore is run as a non-root user (the typical scenario) then all files restored will belong to the user/group executing pgBackRest. If existing files are not owned by the executing user/group then an error will result if the ownership cannot be updated to the executing user/group. In that case the file ownership will need to be updated by a privileged user before the restore can be retried.
If a restore is run as the root user then pgBackRest will attempt to recreate the ownership recorded in the manifest when the backup was made. Only user/group names are stored in the manifest so the same names must exist on the restore host for this to work. If the user/group name cannot be found locally then the user/group of the PostgreSQL data directory will be used and finally root if the data directory user/group cannot be mapped to a name.

This test is commonly used for sanity checking but the combination of S3 and encryption makes it hard to use and encourages temporary changes to make it usable.
Acknowledge this and disable S3 and encryption for this test and move them to mock/all/2.
Prior to 2.16 the Perl manifest code would skip any file that began with a dot. This was not intentional but it allowed PostgreSQL socket files to be located in the data directory. The new C code in 2.16 did not have this unintentional exclusion so socket files in the data directory caused errors.
Worse, the file type error was being thrown before the exclusion check so there was really no way around the issue except to move the socket files out of the data directory.
Special file types (e.g. socket, pipe) will now be automatically skipped and a warning logged to notify the user of the exclusion. The warning can be suppressed with an explicit --exclude.
Reported by CluelessTechnologist, Janis Puris, Rachid Broum.
In versions <= 2.15 the old regexp caused any file or directory beginning with . to be ignored during a backup. This has caused behavioral differences in 2.16 because the new C code correctly excludes ./.. directories.
This Perl code is only used for testing now, but it should still match the output of the C functions.
Putting the checksum at the beginning of the file made it impossible to stream the file out when saving. The entire file had to be held in memory while it was checksummed so the checksum could be written at the beginning.
Instead place the checksum at the end. This does not break the existing Perl or C code since the read is not order dependent.
There are no plans to improve the Perl code to take advantage of this change, but it will make the C implementation more efficient.

For offline backups the upper bound was being set to 0x0000FFFF0000FFFF rather than UINT64_MAX. This meant that page checksum errors might be ignored for databases with a lot of past WAL in offline mode.

Maintaining the storage layer/drivers in two languages is burdensome. Since the integration tests require the Perl storage layer/drivers we'll need them even after the core code is migrated to C. Create an interface layer so the Perl code can be removed and new storage drivers/features introduced without adding Perl equivalents.
The goal is to move the integration tests to C so this interface will eventually be removed. That being the case, the interface was designed for maximum compatibility to ease the transition. The result looks a bit hacky but we'll improve it as needed until it can be retired.

This was not enforced at parse time because repo1-cipher-type could be passed on the command-line even in cases where encryption was not needed by the subprocess.

The C code is designed to be efficient rather than deterministic at the debug log level. As we move more testing from integration to unit tests it makes less sense to try and maintain the expect logs at this log level.

The branch coverage exclusion rules were overly broad and included functions that ended in a capital letter, which disabled all coverage for the statement. Improve matching so that all characters in the name must be upper-case for a match.
Some macros with internal branches accepted parameters that might contain conditionals. This made it impossible to tell which branches belonged to which, and in any case an overzealous exclusion rule was ignoring all branches in such cases. Add the DEBUG_COVERAGE flag to build a modified version of the macros without any internal branches to be used for coverage testing. In most cases, the branches were optimizations (like checking logWill()) that improve production performance but are not needed for testing. In other cases, a parameter needed to be added to the underlying function to handle the branch during coverage testing.
Also tweak the coverage rules so that macros without conditionals are automatically excluded from branch coverage as long as they are not themselves a parameter.
Finally, update tests and code where missing coverage was exposed by these changes. Some code was updated to remove existing coverage exclusions when it was a simple change.
The function pointer casting used when creating drivers made changing interfaces difficult and led to slightly divergent driver implementations. Unit testing caught production-level errors but there were a lot of small issues and the process was harder than it should have been.
Use void pointers instead so that no casts are required. Introduce the THIS_VOID and THIS() macros to make dealing with void pointers a little safer.
Since we don't want to expose void pointers in header files, driver functions have been removed from the headers and the various driver objects return their interface type. This cuts down on accessor methods and the vast majority of those functions were not being used. Move functions that are still required to .intern.h.

When this error happens in the context of a backup it can be a bit mystifying as to why the backup is failing. Add some hints to get the user started.
These hints will appear any time a WAL segment can't be found, which makes the hint about the check command redundant when the user is actually running the check command, but it doesn't seem worth trying to exclude the hint in that case.

Vary the tests per VM to increase coverage while reducing the total number of tests. Be sure to include each major feature (remote, s3, encryption) in each VM at least once.
The prior method depended on IO:Socket:SSL to push the keep-alive options down to the socket but it only worked for recent versions of the module.
Instead, create the socket directly using IO::Socket::IP if available or IO:Socket:INET as a fallback. The keep-alive option is set directly on the socket before it is passed to IO:Socket:SSL.

This new implementation should behave exactly like the old Perl code with the exception of a few updated log messages.
Remove as much of the Perl code as possible without breaking other commands.
The C local is only used for C commands in the main process.
Some tweaking of the existing protocolGet() command was required. Originally the idea was to share the function for local and remote requests but the differences (as in Perl) were too great to make that practical.
This amends 70c30dfb which disabled test tracing in general.
Instead, only enable test tracing by default for modules that are being unit tested. This saves lots of time but still ensures that test tracing is working and helps with debugging in unit tests.
Also rename the option to --debug-test-trace for a clarity.

The expect tests were originally a rough-and-ready type of unit test so monitoring changes in the expect log helped us detect changes in behavior.
Now the stanza code is heavily unit-tested so the detailed logs mainly cause churn and don't have any measurable benefit.
Reduce the log level to DETAIL to make the logs less verbose and volatile, yet still check user-facing log messages.
