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.

7390952d8e Harden IO filters against zero input and optimize zero output case.
Add production checks to ensure no filter gets a zero-size input buffer.

Also, optimize the case where a filter returns no output.  There's no sense in running downstream filters if they have no new input.

2d73de1d36 Fix zero-length reads causing problems for IO filters that did not expect them.
The IoRead object was passing zero-length buffers into the filter processing code but not all the filters were happy about getting them.

In particular, the gzip compression filter failed if it was given no input directly after it had flushed all of its buffers.  This made the problem rather intermittent even though a zero-length buffer was being passed to the filter at the end of every file.  It also explains why tweaking compress-level or buffer-size allowed the file to go through.

Since this error was happening after all processing had completed, there does not appear to be any risk that successfully processed files were corrupted.

b258aec0ad Move lockRelease() to the end of exitSafe().
Releasing the lock too early was allowing other async processes to sneak in and start running before the current process was completely shut down.

The only symptom seems to have been mixed up log messages so not a very serious issue.

b960919cf7 Fix reliability of error reporting from local/remote processes.
Asserts were only only reported on stderr rather than being returned through the protocol layer.  This did not appear to be very reliable.

Instead, report the assert through the protocol layer like any other error.  Add a stack trace if an assert error or debug logging is enabled.

4c13955c05 Add macros to create constant Variant types.
These work almost exactly like the String constant macros. However, a struct per variant type was required which meant custom constructors and destructors for each type.

2dac4b5986 Add STR() macro to create constant String objects from runtime strings.
The STRING_CONST() macro worked fine for constants but was not able to constify strings created at runtime.

Add the STR() macro to do this by using strlen() to get the size.

Also rename STRING_CONST() to STRDEF() for brevity and to match the other macro name.

4e57b68916 v2.12: C Implementation of Archive Push
IMPORTANT NOTE: The new TLS/SSL implementation forbids dots in S3 bucket names per RFC-2818. This security fix is required for compliant hostname verification.

Bug Fixes:

* Fix issues when a path option is / terminated. (Reported by Marc Cousin.)
* Fix issues when log-level-file=off is set for the archive-get command. (Reported by Brad Nicholson.)
* Fix C code to recognize host:port option format like Perl does. (Reported by Kyle Nevins.)
* Fix issues with remote/local command logging options.

Improvements:

* The archive-push command is implemented entirely in C.
* Increase process-max limit to 999. (Suggested by Rakshitha-BR.)
* Improve error message when an S3 bucket name contains dots.

Documentation Improvements:

* Clarify that S3-compatible object stores are supported. (Suggested by Magnus Hagander.)

df12cbb162 Fix C code to recognize host:port format like Perl does.
This was not an intentional feature in Perl, but it works, so it makes sense to implement the same syntax in C.

This is a break from other places where a -port option is explicitly supplied, so it may make sense to support both styles going forward.  This commit does not address that, however.

6099729e92 Improve error message when an S3 bucket name contains dots.
The Perl lib we have been using for TLS allows dots in wildcards, but this is forbidden by RFC-2818.  The new TLS implementation in C forbids this pattern, just as PostgreSQL and curl do.

However, this does present a problem for users who have been using bucket names with dots in older versions of pgBackRest.  Since this limitation exists for security reasons there appears to be no option but to take a hard line and do our best to notify the user of the issue as clearly as possible.

21c83eea59 Fix issue setting log-level-file=off for the archive-get command.
This problem was not specific to archive-get, but that was the only place it was expressing in the last release.  The new archive-push was also affected.

The issue was with daemon processes that had closed all their file descriptors.  When exec'ing and setting up pipes to communicate with a child process the dup2() function created file descriptors that overlapped with the first descriptor (stdout) that was being duped into.  This descriptor was subsequently closed and wackiness ensued.

If logging was enabled (the default) that increased all the file descriptors by one and everything worked.

Fix this by checking if the file descriptor to be closed is the same one being dup'd into.  This solution may not be generally applicable but it works fine in this case.

251dbede8f Add locking capability to the remote command.
When a repository server is configured, commands that modify the repository acquire a remote lock as well as a local lock for extra protection against multiple writers.

Instead of the custom logic used in Perl, make remote locking part of the command configuration.

This also means that the C remote needs the stanza since it is used to construct the lock name.  We may need to revisit this at a later date.

8820d69574 Use a single file to handle global errors in async archiving.
The prior behavior on a global error (i.e. not file specific) was to write an individual error file for each WAL file being processed.  On retry each of these error files would be removed, and if the error was persistent, they would then be recreated.  In a busy environment this could mean tens or hundreds of thousands of files.

Another issue was that the error files could not be written until a list of WAL files to process had been generated.  This was easy enough for archive-get but archive-push requires more processing and any errors that happened when generating the list would only be reported in the pgBackRest log rather than the PostgreSQL log.

Instead write a global.error file that applies to any WAL file that does not have an explicit ok or error file.  This reduces churn and allows more errors to be reported directly to PostgreSQL.

7cf7373761 Refactor PostgreSQL interface to remove most code duplication.
Having a copy per version worked well until it was time to add new features or modify existing functions.  Then it was necessary to modify every version and try to keep them all in sync.

Consolidate all the PostgreSQL types into a single file using #if for type versions.  Many types do not change or change infrequently so this cuts down on duplication.  In addition, it is far easier to see what has changed when a new version is added.

Use macros to write the interface functions.  There is still duplication here since some changes require a new copy of the macro, but it is far less than before.

e26d510d0c Use restore command for remote performances tests.

856a369b86 Add file write to the S3 storage driver.
Now that repositories are writable the storage drivers that don't yet support file writes need to be updated to do so.

Note that the part size for multi-part upload has not been defined as a proper constant.  This will become an option in the near future so it doesn't seem worth creating a constant that we might then forget to remove.

66c2f4cd2e Make notion of current PostgreSQL info ID in C align with Perl.
The C code was assuming that the current PostgreSQL version in archive.info/backup.info was the most recent item in the history, but this is not always the case with some stanza-upgrade scenarios.  If a cluster is restored from before the upgrade and stanza-upgrade is run again, it will revert db-id to the original history item.

Instead, load db-id from the db section explicitly as the Perl code does.

This did not affect archive-get since it does a reverse scan through the history versions and does not rely on the current version.

b2b2cf0511 Fix issues with remote/local command logging options.
Logging was being enable on local/remote processes even if --log-subprocess was not specified, so fix that.

Also, make sure that stderr is enabled at error level as it was on Perl.  This helps expose error information for debugging.

For remotes, suppress log and lock paths since these are not applicable on remote hosts.  These options should be set in the local config if they need to be overridden.

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.

c307d9fdf9 Don't make a copy of the context name in the MemContext module.
This is very inefficient in terms of memory and time and dynamic context names were never utilized.

Just require that context names be valid for the life of the context.

In practice they are all static strings.

90709dfd21 Improve performance of context and memory allocations in MemContext module.
Allocations required a sequential scan through the allocation list for both contexts and memory.  This was very inefficient since for the most part individual memory allocations are seldom freed directly, rather they are freed when their context is freed.

For both types of allocations track an index for the lowest free position.  After an allocation of the free position, a sequential search will be required for the next allocation but this is still far better than doing a scan for every allocation.

With a moderately-sized dataset (500 history entries in backup.info), there is a 237X performance improvement when combined with the f74e88bb refactor.

Before:

  %   cumulative   self
 time   seconds   seconds name
 65.11    331.37   331.37 memContextAlloc
 16.19    413.78    82.40 memContextCurrent
 14.74    488.81    75.03 memContextTop
  2.65    502.29    13.48 memContextNewIndex
  1.18    508.31     6.02 memFind

After:

  %   cumulative   self
 time   seconds   seconds name
 94.69      2.14     2.14 memFind

Finding memory allocations in order to free or resize them is the next bottleneck, but this does not seem to be a major issue presently.

f74e88bba9 Use contextTop/contextCurrent instead of memContextTop()/memContextCurrent() in MemContext module.
Using the functions internally is great for abstraction but not so great for performance on non-optimized builds.

Also, the functions end up prominent in any profiled build.

4093609241 Documentation builds on PostgreSQL 9.4-10.
More than likely 9.2-11 will work as well, but this has not been tested.

However, 11 needs work on the group permissions introduced in that version.

cb3b4fa24b Enable socket keep-alive on older Perl versions.
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.

db4b447be8 The archive-get command is implemented entirely in C.
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.

9367cc461c Migrate local command to C.
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.

dee90d3e60 Expose handle (file descriptor) from IoRead when applicable.
Some IO objects have file descriptors which can be useful for monitoring with select().

It might also be useful to expose handles for write objects but there is currently no use case.

4be271ea2a Improve fork harness to allow multiple children and setup pipes automatically.
There was a lot of extra boilerplate involved in setting up pipes so that is now automated.

In some cases testing with multiple children is useful so allow that as well.

18b62a4220 Only run test-level stack trace by default for unit-tested modules.
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.

3a05359087 Create test matrix for mock/stanza to increase coverage and reduce tests.
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.

6d3e18b181 Reduce expect log level in mock/stanza tests.
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.

1f66bda02e Fix non-compliant JSON for options passed from C to Perl.
We have been using a hacked-up JSON generator to pass options from C to Perl since the C binary was introduced.  This generator was not very compliant which led to issues with \n, ", etc. inside strings.

We have a fully-compliant JSON generator now so use that instead.
