The prior method of tailing the docker log no longer seems reliable. Instead, keep retrying the make bucket command until it works and show the error if it times out.
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.
Filter repo-cipher-type so it is never passed on the command line. If the subprocess does not have access to the passphrase then knowing the encryption type is useless anyway.
The documentation was relying on a ScalityS3 container built for testing which wasn't very transparent. Instead, use the stock minio container and configure it in the documentation.
Also, install certificates and CA so that TLS verification can be enabled.
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.
Most of the expect logs have already been moved to detail level but mock/all still had tests at debug level. Change the logging defaults in the config file and remove as many references to log-level-console as possible.
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.

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.
