The C code can't get the cipher type from the storage object because the C storage object does not have encryption baked in like the Perl code does.
Instead, check backup.info to see if encryption is enabled. This will need to rethought if another cipher type is added but for now it works fine.
Replace the repository path with just "the repository". The path is not important in this context and it is clearer to state where the stanzas are missing from.
The Perl code has a tendency to generate absolute paths even when they are not needed. This change helps the C and Perl storage work together via the protocol layer.
The C storage object strives to use rules whenever possible instead of generating absolute paths. This change helps the C and Perl storage work together via the protocol layer.
The prior behavior was to throw an exception but this was not very helpful when something unexpected happened. Better to at least emit the error message even if the error code is not very helpful.
There were some small differences in ordering and how the C version handled missing directories. It may be that the C version is more consistent, but for now it is more important to be compatible with the Perl version.
These differences were missed because the C info command was not wired into main.c so it was not being tested in regression. This commit does not fix the wiring issue because there will likely be a release soon and it is too big a change to put in at the last moment.
Casting to int caused large values to be slightly inaccurate so cast to uint64_t instead.
Also, use multiplication where possible since the compiler should precompute multiplied values.
SIGPIPE immediately terminates the process but we would rather catch the EPIPE error and gracefully shutdown.
Ignore SIGPIPE and throw the EPIPE error via normal error handling.
For some reason adding -D_POSIX_C_SOURCE=200112L caused MacOS builds to stop working. Combining both flags seems to work fine for all tested systems.

Including the C module after the headers required for testing meant that if headers were missing from the C module they were not caught while directly testing the C module.
The missing headers were caught in general testing, but it is frustrating to get an error in a module that has already passed while testing another module or running CI.
Move the C module include to the very top so missing headers cause immediate failures.
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.)
Admonitions call out places where the user should take special care.
Support added for HTML, PDF, Markdown and help text renderers. XML files have been updated accordingly.

A number of common characters are not allowed in latex without being escaped.
Also convert some HTML-specific codes that are used in the documentation.

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.

This was caused by a new container version that was released around December 5th. The new version explicitly denies user logons by leaving /var/run/nologin in place after boot.
The solution is to enable the service that is responsible for removing this file on a successful boot.
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.
