These functions are not required for repository storage so make them optional and error if they are not implemented for non-repository storage, .e.g. pg or spool.
The goal is to simplify the drivers (e.g. S3) that are intended only for repository storage.
The prior behavior was to return NULL so the caller would know the path was missing, but this is rarely useful, complicates the calling code, and increases the chance of segfaults.
The .nullOnMissing param has been added to enable the prior behavior.
Since the CentOS 6/7 user guides were generated as a single page they did not get menus. Generate the entire site for each user guide so menus are included.
The release notes are generally a direct reflection of the git log. So, ease the burden of maintaining the release notes by using the git log to determine what needs to be added.
Currently only non-dev items are required to be matched to a git commit but the goal is to account for all commits.
The git history cache is generated from the git log but can be modified to correct typos and match the release notes as they evolve. The commit hash is used to identify commits that have already been added to the cache.
There's plenty more to do here. For instance, links to the commits for each release item should be added to the release notes.
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.
/ is escaped in the spec but the Perl renderer we use does not escape it which leads to checksum mismatches between the two sets of code.
This particular escape seems to be a more recent addition to the spec and is targeted toward embedding JSON in JavaScript.
\/ is still allowed when parsing JSON.
The first paragraph should match the first line of the commit message as closely as possible. The following paragraphs add more information.
Release items have been updated back to 2.01.
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 is just the part of restore run by the local helper processes, not the entire command.
Even so, various optimizations in the code (like pipelining and optimizations for zero-length files) should make the restore command faster on object stores.
Bug Fixes:
* Fix segfault when process-max > 8 for archive-push/archive-get. (Reported by Jens Wilke.)
Improvements:
* Bypass database checks when stanza-delete issued with force. (Contributed by Cynthia Shang. Suggested by hatifnatt.)
* Add configure script for improved multi-platform support.
Documentation Features:
* Add user guides for CentOS/RHEL 6/7.
It would be better if the documentation could be generated on multiple operating systems all in one go, but the doc system currently does not allow vars to be changed once they are set.
The solution is to run the docs for each required OS and stitch the documentation together. It's not pretty but it works and the automation in release.pl should at least make it easy to use.
The url for the menu item referring to the index (i.e. site root page) should use {[project-url-root]}.
This allows the url to be set to different values depending on the location of the index.
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.
There are currently no options with multiple alternate (deprecated) names so the code to render them in the help command could not be covered.
Remove the uncovered code and add an error when multiple alternate names are configured. It's not clear that the current code was handling this correctly, so it will need to be reviewed if it comes up again.
Pre-calculate the value used by logAny() to improve performance and make it more likely to be inlined.
Move IF_LOG_ANY() into LOG_INTERNAL() to simplify the macros and improve performance of LOG() and LOG_PID(). If the message has no chance of being logged there's no reason to call logInternal().
Rename logWill() to logAny() because it seems more intuitive.
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.
Call stackTraceTestStop()/stackTraceTestStart() once per block instead of with every param call. This was done to be cautious but is not necessary and slows down development.
These functions were never built into production so had no impact there.
Filters had different ideas about what "done" meant and this added complication to the group filter processing. For example, gzip decompression would detect end of stream and mark the filter as done before it had been flushed.
Improve the IoFilter interface to give a consistent definition of done across all filters, i.e. no filter can be done until it has started flushing no matter what the underlying driver reports. This removes quite a bit of tricky logic in the processing loop which tried to determine when a filter was "really" done.
Also improve management of the input buffers by pointing directly to the prior output buffer (or the caller's input) to eliminate loops that set/cleared these buffers.
If content was zero-length then the IO object was not created. This put the burden on the caller to test that the IO object existed before checking eof.
Instead, create an IO object even if it will immediately return eof. This has little cost and makes the calling code simpler.
Also add an explicit test for zero-length files in S3 and a few assertions.
The rules for when a C remote is required are getting complicated and will get worse when restoreFile() is migrated.
Instead, set the --c option when a C remote is required. This option will be removed when the remote is entirely implemented in C.
Most of the *Free() functions are pretty generic so add macros to make creating them as easy as possible.
Create a distinction between *Free() functions that the caller uses to free memory and callbacks that free third-party resources. There are a number of cases where a driver needs to free resources but does not need a normal *Free() because it is handled by the interface.
Add common/object.h for macros that make object maintenance easier. This pattern can also be used for many more object functions.
Rename memContextCallback() to memContextCallbackSet() to be more consistent with other parts of the code.
Free all context memory when an exception is thrown from a callback. Previously only the child contexts would be freed and this resulted in some allocations being lost. In practice this is probably not a big deal since the process will likely terminate shortly, but there may well be cases where that is not true.
Add GLUE() macro which is useful for creating identifiers.
Move MACRO_TO_STR() here and rename it STRINGIFY(). This appears to be the standard name for this type of macro and it is also an awesome name.
