The new name is preferred because pgBackRest does not support any SSL protocol versions (they are all considered to be insecure).
The old name will continue to be accepted.
This report replaces the lcov report that was generated manually for each release.
The lcov report was overly verbose just to say that we have virtually 100% coverage.
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.
Remove the special "C" crypto functions that were used in libc and instead use the standard interface.
Use autoconf to provide a basic configure script. WITH_BACKTRACE is yet to be migrated to configure and the unit tests still use a custom Makefile.
Each C file must include "build.auto.conf" before all other includes and defines. This is enforced by test.pl for includes, but it won't detect incorrect define ordering.
Update packages to call configure and use standard flags to pass options.
Update RHEL repos that have changed upstream. Remove PostgreSQL 9.3 since the RHEL6/7 packages have disappeared.
Remove PostgreSQL versions from U12 that are still getting minor updates so the container does not need to be rebuilt.
LZ4 is included for future development, but this seems like a good time to add it to the containers.
Bug Fixes:
* Fix zero-length reads causing problems for IO filters that did not expect them. (Reported by brunre01, jwpit, Tomasz Kontusz, guruguruguru.)
* Fix reliability of error reporting from local/remote processes.
* Fix Posix/CIFS error messages reporting the wrong filename on write/sync/close.
This new implementation should behave exactly like the old Perl code with the exception of updated log messages.
Remove as much of the Perl code as possible without breaking other commands.
The test harness was not being built with warnings which caused some wackiness with an improperly structured switch. Just use the same warnings as the code being tested.
Also enable warnings on code that is not directly being tested since other code modules are frequently modified during testing.
Since archive-push is being moved to C, the Perl remote will no longer work with that command.
Eventually this module will need to be rewritten in C, but for now just use the restore command which is planned to be migrated last.
This condition was not being properly checked for in the C code and it caused problems in the info command, at the very least.
Instead of applying a local fix, introduce a new path option type that will rigorously check the format of any incoming paths.
Reported by Marc Cousin.
This command was previously forked off from the archive-push command which required a bit of artificial option and log manipulation.
A separate command is easier to test and will work on platforms that don't have fork(), e.g. Windows.
Add the buffer-size, compress-level, compress-level-network, and process-max options to the backup:option section in backup.manifest to aid in debugging.
It may also make sense to propagate these options up to backup.info so they can be displayed in the info command, but for now this is deemed sufficient.
Contributed by blogh.
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.
Suggested by Hans-Jürgen Schönig.
The same test configurations are run on all four test VMs, which seems a real waste of resources.
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.

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.

Detailed stack traces for low-level functions (e.g. strCat, bufMove) can be very useful for debugging but leaving them on for all tests has become quite burdensome in terms of time. Complex operations like generating JSON on a large KevValue can lead to timeouts even with generous values.
Add a new param, --debug-trace, to enable test-level stack trace, but leave it off by default.
The file write object destructors called close() and finalized the file even if it was not completely written. This was an issue in both the C and Perl code.
Rewrite the destructors to simply free resources (like file handles) rather than calling the close() method. This leaves the temp file in place for filesystems that use temp files.
Add unit tests to prevent regression.
Reported by blogh.
This was not being caught because the integration tests for S3 were running remotely and going through the Perl code rather than the new C code.
Implement the exists method for the S3 driver and add tests to prevent a regression.
Reported by mibiio.
Multiple status files were being created by asynchronous archiving if a high-level error occurred after one or more WAL segments had already been transferred successfully. Error files were being written for every file in the queue regardless of whether it had already succeeded. To fix this, add an option to skip writing error files when an ok file already exists.
There are other situations where both files might exist (various fsync and filesystem error scenarios) so it seems best to retry in the case that multiple status files are found rather than throwing a hard error (which then means that archiving is completely stuck). In the case of multiple status files, a warning will be logged to alert the user that something unusual is happening and the command will be retried.
Reported by fpa-postgres, Joe Ayers, Douglas J Hunley.
The C info code has already been committed but this commit wires it into main.
Also remove the info Perl code and tests since they are no longer called.
Bug Fixes:
* Remove request for S3 object info directly after putting it. (Reported by Matt Kunkel.)
* Correct archive-get-queue-max to be size type. (Reported by Ronan Dunklau.)
* Add error message when current user uid/gid does not map to a name. (Reported by Camilo Aguilar.)
* Error when --target-action=shutdown specified for PostgreSQL < 9.5.
Improvements:
* Set TCP keepalives on S3 connections. (Suggested by Ronan Dunklau.)
* Reorder info command text output so most recent backup is output last. (Contributed by Cynthia Shang. Suggested by Ryan Lambert.)
* Change file ownership only when required.
* Redact authentication header when throwing S3 errors. (Suggested by Brad Nicholson.)
After a stanza-upgrade backups for the old cluster are displayed until they expire. Cluster info was output newest to oldest which meant after an upgrade the most recent backup would no longer be output last.
Update the text output ordering so the most recent backup is always output last.

- Add detail to errors when info files are loaded with incorrect encryption settings.
- Throw FileMissingError rather than FileOpenError when both copies of the info file are missing.
- If one file is present (but errors) and the other is missing, then return the error for the file that was present.

Previously chown() would be called even when no ownership changes were required.
In most cases changes are not required and it seems better to perform an extra stat() rather than an extra chown().
Also add unit tests for owner() since there weren't any.
This got missed in 1f8931f7 when the test binary was renamed.
Also output call graph along with the flat report. The flat report is generally most useful but it doesn't hurt to have both.
The previous error message only showed the last error. In addition, some errors were missed (such as directory permission errors) that could prevent the copy from being checked.
Show both errors below a generic "unable to load" error. Details are now given explaining exactly why the primary and copy failed.
Previously if one file could not be loaded a warning would be output. This has been removed because it is not clear what the user should do in this case. Should they do a stanza-create --force? Maybe the best idea is to automatically repair the corrupt file, but on the other hand that might just spread corruption if pgBackRest makes the wrong choice.
The decryption filter was added in archiveGetFile() and archiveGetCheck() was modified to return the WAL decryption key stored in archive.info. The rest was plumbing.
The mock/archive/1 integration test added encryption to provide coverage for the new code paths while mock/archive/2 dropped encryption to provide coverage for the existing code paths. This caused some churn in the expect logs but there was no change in behavior.
The only change required was to remove the filter that prevented S3 storage from being used. The archive-get command did not require any modification which demonstrates that the storage interface is working as intended.
The mock/archive/3 integration test was modified to run S3 storage locally to provide coverage for the new code paths while mock/stanza/3 was modified to run S3 storage remotely to provide coverage for the existing code paths. This caused some churn in the expect logs but there was no change in behavior.
Test certificates were generated dynamically but there are advantages to using static certificates. For example, it possible to use the same certificate between container versions. Mostly, it is easier to document the certificates if they are not buried deep in the container code.
The new test certificates are initially intended to be used with the C unit tests but they will eventually be used for integration tests as well.
Two new certificates have been defined. See test/certificate/README.md for details.
The old dynamic certificates will be retained until they are replaced.
Add XmlDocument, XmlNode, and XmlNodeList objects as a thin interface layer on libxml2.
This interface is not intended to be comprehensive. Only a few libxml2 capabilities are exposed but more can be added as needed.
This allows a C unit test to access data in the code repository that might be useful for testing.
Add testRepoPathSet() to set the repository path.
In passing remove extra whitespace in the TEST_RESULT_VOID() macro.
If the last } of a function was marked as uncovered then the context selection would overrun into the next function.
Start checking context on the current line to prevent this. Make the same change for start context even though it doesn't seem to have an issue.
Too few lines were shown for coverage context so show the entire function if it has any missing coverage.
Update colors to work with light and dark browser modes.
The report HTML generated by lcov is overly verbose and cumbersome to navigate. Since we maintain 100% coverage it's far more interesting to look at what is not covered than what is.
The new report presents all missing coverage on a single page and excludes code that is covered for brevity.
Code generation saved files even when they had not changed, which often caused code generation cascades. So, don't save files unless they have changed.
Use rsync to determine which files have changed since the last test run. The manifest of changed files is saved and not removed until all code generation and builds have completed. If an error occurs the work will be redone on the next run.
The eventual goal is to do all the builds from the test/repo directory created by rsync but for now it is only used to track changes.
Improve on 7794ab50 by including the build flag files directly into the Makefile as dependencies (even though they are not includes). This simplifies some of the rsync logic and allows make to do what it does best.
Also split build flag files into test, harness, and build to reduce rebuilds. Test flags are used to build test.c, harness flags are used to build the rest of the files in the test harness, and build flags are used for the files that are not directly involved in testing.
The contents were already preserved between tests in a single test.pl run but for a separate execution the entire project had to be built from scratch, which was getting slower as we added code.
Save the important build flags in a file so the new execution knows whether the build contents can be reused.
There are a number of cases where a checksum delta is more appropriate than the default time-based delta:
* Timeline has switched since the prior backup
* File timestamp is older than recorded in the prior backup
* File size changed but timestamp did not
* File timestamp is in the future compared to the start of the backup
* Online option has changed since the prior backup
A practical example is that checksum delta will be enabled after a failover to standby due to the timeline switch. In this case, timestamps can't be trusted and our recommendation has been to run a full backup, which can impact the retention schedule and requires manual intervention.
Now, a checksum delta will be performed if the backup type is incr/diff. This means more CPU will be used during the backup but the backup size will be smaller and the retention schedule will not be impacted.

We were already retrying 500 errors but 503 (rate-limiting) errors were not being retried and would cause an instant failure which aborted the command.
There are only two 5xx errors currently implemented by S3 but instead of adding 503 simply retry all 5xx errors. This is consistent with the http definition of this error class, "the server failed to fulfill an apparently valid request."
Suggested by Craig A. James.
This calculation was missed when the WAL segment size was made dynamic in preparation for PostgreSQL 11.
Fix the calculation by checking the actual WAL file sizes instead of using an estimate based on WAL segment size. This is more accurate because it takes into account .history and .backup files, which are smaller. Since the calculation is done in the async process the additional processing time should not adversely affect performance.
Remove the PG_WAL_SIZE constant and instead use local constants where the old value is still required. This is only the case for some tests and PostgreSQL 8.3 which does not provide a way to get the WAL segment size from pg_control.
If an error occurred while acquiring a lock on a remote server the error would be reported correctly, but the queue max detection code was not reached. The tests failed to detect this because they fixed the connection before queue max, allowing the ccde to be reached.
Move the queue max code before the lock so it will run even when remote connections are not working. This means that no attempt will be made to transfer WAL once queue max has been exceeded, but it makes it much more likely that the code will be reach without error.
Update tests to continue errors up to the point where queue max is exceeded.
Reported by Lardière Sébastien.
The standard npm packages on Ubuntu 18.04 suddenly required libssl1.0 which broke the pgbackrest package builds. Installing nodejs from deb.nodesource.com seems to work fine with standard libssl.
This package is required by ScalityS3 which is used for local S3 testing.
PostgreSQL 11 introduces configurable WAL segment sizes, from 1MB to 1GB.
There are two areas that needed to be updated to support this: building the archive-get queue and checking that WAL has been archived after a backup. Both operations require the WAL segment size to properly build a list.
Checking the archive after a backup is still implemented in Perl and has an active database connection, so just get the WAL segment size from the database.
The archive-get command does not have a connection to the database, so get the WAL segment size from pg_control instead. This requires a deeper inspection of pg_control than has been done in the past, so it seemed best to copy the relevant data structures from each version of PostgreSQL and build a generic interface layer to address them. While this approach is a bit verbose, it has the advantage of being relatively simple, and can easily be updated for new versions of PostgreSQL.
Since the integration tests generate pg_control files for testing, teach Perl how to generate files with the correct offsets for both 32-bit and 64-bit architectures.
Use checksums rather than timestamps to determine if files have changed. This is useful in cases where the timestamps may not be trustworthy, e.g. when performing an incremental after failing over to a standby.
If checksum delta is enabled then checksums will be used for verification of resumed backups, even if they are full. Resumes have always used checksums to verify the files in the repository, enabling delta performs checksums on the database files as well.
Note that the user must manually enable this feature in cases were it would be useful or just keep in enabled all the time. A future commit will address automatically enabling the feature in cases where it seems likely to be useful.

This is a workaround for inefficient handling of many setjmps in gcc >= 4.9. Setjmp is used in all error handling, but in the unit tests each test macro contains an error handling block so they add up pretty quickly for large unit tests.
Enabling -ftree-coalesce-vars in affected versions reduces build time and memory requirements by nearly an order of magnitude. Even so, compiles are much slower than gcc <= 4.8.
We submitted a bug for this at: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87316
Which was marked as a duplicate of: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63155
For read-only repositories the Posix and CIFS drivers behave exactly the same. Since that's all we support in C right now it's valid to treat them as the same thing. An assertion has been added to remind us to add the CIFS driver before allowing the repository to be writable.
Mostly we want to make sure that the C code does not blow up when the repository type is CIFS.
Storing the expect log (created by common/harnessLog) in the regular test directory was not ideal. It showed up in tests and made it difficult to clear the test directory between each run.
Move the expect log to a purpose-built directory one level up so it does not interfere with regular testing.
C or Perl coverage tests can now be run on any VM provided a recent enough version of Devel::Cover or lcov is available.
For now, leave u18 as the only VM to run coverage tests due to some issues with older versions of lcov.
% characters caused issues in backup/restore due to filenames being appended directly into a format string.
Reserved XML characters (<>&') caused issues in the S3 driver due to improper escaping.
Add a file with all common special characters to regression testing.
By default Valgrind does not exit with an error code when a non-fatal error is detected, e.g. unfreed memory. Use the --error-exitcode option to enabled this behavior.
Update some minor issues discovered in the tests as a result. Luckily, no issues were missed in the core code.
The new archive-get C code can't run (yet) when encryption is enabled. Therefore move the encryption tests so we can test the new C code. We'll move it back when encryption is enabled in C.
Also, push one WAL segment with compression to test decompression in the C code.
A return code of 1 from the archive-get was being logged as an error message at info level but otherwise worked correctly.
Also improve info messages when an archive segment is or is not found.
Previously an error would be generated if other files were present and not owned by the PostgreSQL user. This hasn't been a big deal in practice but it could cause issues.
Also add tests to make sure the same logic applies with links to files, i.e. all other files in the directory should be ignored. This was actually working correctly, but there were no tests for it before.
The log-subprocess feature added in 22765670 failed to take into account the naming for remote processes spawned by local processes. Not only was the local command used for the naming of log files but the process id was not pass through. This meant every remote log was named "[stanza]-local-remote-000" which is confusing and meant multiple processes were writing to the same log.
Instead, pass the real command and process id to the remote. This required a minor change in locking to ignore locks if process id is greater than 0 since remotes started by locals never lock.
Relative link paths were being combined with the paths of previous links (relative or absolute) due to the $strPath variable being modified in the current iteration rather than simply being passed to the next level of recursion.
This issue did not affect absolute links and relative tablespace links were caught by other checks, though the error was confusing.

Offline operation runs counter to the purpose of this command, which is to check if archiving and backups are working correctly.
Reported by Jason O'Donnell.
Implemented using the same logic as the patches adding this feature to PostgreSQL, 8694cc96 and 920a5e50. Temporary relation exclusion is enabled in PostgreSQL ≥ 9.0. Unlogged relation exclusion is enabled in PostgreSQL ≥ 9.1, where the feature was introduced.

This allows setting the test log level independently from the general test harness setting, but current only works for the C tests. It is useful for seeing log output from functions on the console while a test is running.
This is more efficient overall and allows the caller to specify how many bytes will be read on each call. Reads are appended if the buffer already contains data but the buffer size will never increase.
Allow Buffer object "used size" to be different than "allocated size". Add functions to manage used size and remaining size and update automatically when possible.
A regression in v0.82 removed the timestamp comparison when deciding which files from the aborted backup to keep on resume. All resumed backups should be considered inconsistent. A resumed backup can be identified by checking the log for the message "aborted backup of same type exists, will be cleaned to remove invalid files and resumed".

* Use time_t instead of __time_t for better portability. (Suggested by Nick Floersch.)
* Print total runtime in milliseconds at command end.
Low-level functions only include stack trace in test builds while higher-level functions ship with stack trace built-in. Stack traces include all parameters passed to the function but production builds only create the parameter list when the log level is set high enough, i.e. debug or trace depending on the function.

Mainly this helps with unit tests that need to do log expect testing. Add harnessCfgLoad() test function, which allows a new config to be loaded for unit testing without resetting log functions, opening a log file, or taking locks.
The Perl process was exiting directly when called but that interfered with proper locking for the forked async process. Now Perl returns results to the C process which handles all errors, including signals.
Now only two types of locks can be taken: archive and backup. Most commands use one or the other but the stanza-* commands acquire both locks. This provides better protection than the old command-based locking scheme.
This makes it easier to create objects and then copy them to another context when they are complete without having to worry about freeing them on error. Update List, StringList, and Buffer to allow moves. Update Ini and Storage to take advantage of moves.
Switch from Devel::Cover because it would not report on branch coverage for reports converted from gcov.
Branch coverage is not complete, so for the time being errors will only be generated when statement coverage is not complete. Coverage of unit tests is not displayed in the report unless they are incomplete for either statement or branch coverage.
* Replace remaining NDEBUG blocks with the more granular DEBUG_UNIT.
* Remove some debug memset() calls in MemContext since valgrind is more useful for these checks.
Move command begin to C except when it must be called after another command in Perl (e.g. expire after backup). Command begin logs correctly for complex data types like hash and list. Specify which commands will log to file immediately and set the default log level for log messages that are common to all commands. File logging is initiated from C.
Buffering now takes the pending bytes on the socket into account (when present) rather than relying entirely on select(). In some instances the final bytes would not be flushed until the connection was closed.
The coverage report shows some code as never being run -- but that makes no sense because the tests pass. This may be due to trying to combine the C and Perl coverage reports and overwriting some runs.
Suppress for now with a plan to implement LCOV for the C unit tests.
This provides correct matching in the event there are system-id and db-version duplicates (e.g. after reverting a pg_upgrade).

This allows specific options in pgbackrest.conf to be ignored (and set to default) which reduces the need to write new configuration files for specific needs.
Note that boolean, non-command-line options are already negatable.

When more than one db was specified the path, port, and socket path would for db1 were passed no matter which db was actually being addressed.
Reported by Uspen.
If the backup cannot map a group to a name it stores the group in the manifest as false then uses either the owner of $PGDATA to set the group during restore or failing that the group of the current user. This logic was not working correctly because the selected group was overwriting the user on restore leaving the group undefined and the user incorrectly set to the group. (Reported by Jeff McCormick.)
The existing static files would not work with 32-bit or big-endian systems so create functions to generate these files dynamically rather than creating a bunch of new static files.
Running coverage testing on multiple distros takes time but doesn't add significant value. Also ensure that the distro designated to run coverage tests is one of the default test distros.
After a stanza-upgrade it should still be possible to restore backups from the previous version and perform recovery with archive-get. However, archive-get only checked the most recent db version/id and failed.
Also clean up some issues when the same db version/id appears multiple times in the history.
