Keepalives may help in situations where RST packets are being blocked by a firewall or otherwise do not arrive.
The C code uses select on all reads so it should never block, but add keepalives just in case.

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.

The info command will only be executed in C if the repository is local, i.e. not located on a remote repository host. S3 is considered "local" in this case.
This is a direct migration from Perl to integrate as seamlessly with the remaining Perl code as possible. It should not be possible to determine if the C version is running unless debug-level logging is enabled.

The infoBackup object is the counterpart to the infoArchive object which encapsulates the archive.info file.
Currently the object is read-only, i.e. it is not possible to create a new or modify an existing backup.info file.
There a number of constants that will also be used in the infoManifest object so go ahead and create a module to contain them so they don't need to be moved later.

The previous way worked but was a head-scratcher when reading the code. This cast hopefully makes it a bit more obvious what is going on.

INFO is generally used as the prefix for info file constants so rename these accordingly.
Also follow newly-adopted coding standards for when #define is required for a static String constant.

Some commands (e.g. info) do not take a stanza or the stanza is optional. In that case it is the job of the command to construct the repository path with a stanza as needed.
Update helper functions to omit the stanza from the constructed path when it is NULL.

- 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.

This code was generated during testing and it seemed a good idea to keep it. It is only a partial solution since the primary also needs additional configuration to be able to fail back and forth.
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.
The authentication header contains the access key (not the secret key) so don't include it in errors that can be seen at any log level.
Suggested by Brad Nicholson.
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.
By default the documentation builds pgBackRest from source, but the documentation is also a good way to smoke-test packages.
Allow a package file to be specified by passing --var=package=/path/to/package.ext. This works for Debian and CentOS 6 builds.
Keywords were extremely limited and prevented us from generating multi-version documentation and other improvements.
Replace keywords with an if statement that can evaluate a Perl expression with variable replacement.
Since keywords were used to generate cache keys, add a --key-var parameter to identify which variables should make up the key.
This somehow was not configured as a size option when it was added. It worked, but queue sizes could not be specified in shorthand, e.g. 128GB.
This is not a breaking change because currently configured integer values will be read as bytes.
Reported by Ronan Dunklau.
After a file is copied during backup the size is requested from the storage in case it differs from what was written so that repo-size can be reported accurately. This is useful for situations where compression is being done by the filesystem (e.g. ZFS) and what is stored can differ in size from what was written.
In S3 the reported size will always be exactly what was written so there is no need to check the size and doing so immediately can cause problems because the new file might not appear in list commands. This has not been observed on S3 (though it seems to be possible) but it has been reported on the Swift S3 gateway.
Add a driver capability to determine if size needs to be called after a file is written and if not then simply use the number of bytes written for repo-size.
Reported by Matt Kunkel.
This allows the documentation to be built more quickly and offline during development when --pre is specified on the command line.
Each host gets a pre-built container with all the execute elements marked pre. As long as the pre elements do not change the container will not need to be rebuilt.
The feature should not be used for CI builds as it may hide errors in the documentation.
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.
If InOut filters were placed next to each other then the second filter would never get a NULL input signaling it to flush. This arrangement only worked if the second filter had some other indication that it should flush, such as a decompression filter where the flush is indicated in the input stream.
This is not a live issue because currently no InOut filters are chained together.
This allows CipherBlock to be used as a filter in an IoFilterGroup. The C-style functions used by Perl are now deprecated and should not be used for any new code.
Also add functions to convert between cipher names and CipherType.
Add boolean and one-dimensional list types to jsonToKv().
Add varToJson() and kvToJson() to convert Variants and KeyValues to JSON.
