Allow Buffer object used size
to be different than allocated size
. Add functions to manage used size and remaining size and update automatically when possible.
Abstract IO layer out of the storage layer. This allows the routines to be used for IO objects that do not have a storage representation. Implement buffer read and write IO objects. Implement filters and update cryptoHash to use the new interface. Implement size and buffer filters.
storageFileRead() accepts a buffer for output rather than creating one. This is more efficient overall and allows the caller to specify how many bytes will be read on each call. Reads are appended if the buffer already contains data but the buffer size will never increase.
Add iniSectionList() to Ini object and remove dead code.
Manifest improvements. Require Manifest object (and not loading it from disk). Prevent manifest from being built more than once. Limit manifest build recursion (i.e. links followed) to sixteen levels to detect link loops.

Allow containers to be defined in a document. The defined containers are built before the document build begins which allows them to be reused.
Move most host setup to containers defined in the documentation. This includes
Error if LibC build is performed outside the test environment. LibC is no longer required for production builds.
Use pre-built images from Docker Hub when the container definition has not changed. Downloading an image is quite a bit faster than building a new image from scratch and saves minutes per test run in CI.
Refactor the common/log tests to not depend on common/harnessLog. common/harnessLog was not ideally suited for general testing and made all the tests quite awkward. Instead, move all code used to test the common/log module into the logTest module and repurpose common/harnessLog to do log expect testing for all other tests in a cleaner way. Add a few exceptions for config testing since the log levels are reset by default in config/parse.
Add
Improve error reporting for TEST_ASSIGN() and TEST_RESULT_VOID() macros.
Update code count for new file types and exclusions.
IMPORTANT NOTE: This release fixes a critical bug in the backup resume feature. All resumed backups prior to this release should be considered inconsistent. A backup will be resumed after a prior backup fails, unless aborted backup of same type exists, will be cleaned to remove invalid files and resumed
. If the message exists, do not use this backup or any backup in the same set for a restore and check the restore logs to see if a resumed backup was restored. If so, there may be inconsistent data in the cluster.
Fix critical bug in resume that resulted in inconsistent backups. A regression in

Move async forking and more error handling to C. The Perl process was exiting directly when called but that interfered with proper locking for the forked async process. Now Perl returns results to the C process which handles all errors, including signals.
Improved lock implementation written in C. Now only two types of locks can be taken:
Storage object improvements. Convert all functions to variadic functions. Enforce read-only storage. Add storageLocalWrite() helper function. Add storageCopy(), storageExists(), storageMove(), storageNewRead()/storageNewWrite(), storagePathCreate(), storagePathRemove(), storagePathSync(), and storageRemove(). Add StorageFileRead and StorageFileWrite objects. Abstract Posix driver code into a separate module. Call storagePathRemove() from the Perl Posix driver.
Improve String and StringList objects. Add strUpper(), strLower(), strLstExists(), strLstExistsZ(), strChr(), strSub(), strSubN(), and strTrunc().
Improve Buffer object. Add bufNewC(), bufEq() and bufCat(). Only reallocate buffer when the size has changed.
Add pgControlInfo() to read
Add walSegmentNext() and walSegmentRange().
Error handling improvments. Add THROWP_* macro variants for error handling. These macros allow an ErrorType pointer to be passed and are required for functions that may return different errors based on a parameter. Add _FMT variants for all THROW macros so format types are checked by the compiler.
Split cfgLoad() into multiple functions to make testing easier. Mainly this helps with unit tests that need to do log expect testing.
Allow MemContext objects to be copied to a new parent. This makes it easier to create objects and then copy them to another context when they are complete without having to worry about freeing them on error. Update List, StringList, and Buffer to allow moves. Update Ini and Storage to take advantage of moves.
Full branch coverage in C code.
Refactor common/time.c. The implementation provides
Replace THROW_ON_SYS_ERROR() with THROW_SYS_ERROR(). The former macro was hiding missing branch coverage for critical error handling.
Start work on C handle io object and use it to output help.
Don't copy
Split debug and assert code into separate headers. Assert can be used earlier because it only depends on the error-handler and not logging. Add ASSERT() macro which is preserved in production builds.

Improve code documentation in config module.
Improve debugging. Add ASSERT_DEBUG() macro for debugging and replace all current assert() calls except in tests that can't use the debug code. Replace remaining NDEBUG blocks with the more granular DEBUG_UNIT. Remove some debug memset() calls in MemContext since valgrind is more useful for these checks.
Add cfgOptionTest() and update cfgOption() calls that are better implemented as cfgOptionTest().
Build with
Check int size in common/type.h. This ensures that integers are at least 32-bits without having to run the test suite.
Improve conversion of C exceptions to Exception objects. Colons in the message would prevent all of the message from being loaded into the Exception object.
Show index in examples for indexed options, i.e.
Simplify table of contents on command page by only listing commands.
Remove references to the C library being optional.
Add CentOS/RHEL package builds.

Add 30 second wait loop to lockAcquire() when fail on no lock enabled. This should help prevent processes that are shutting down from interfering with processes that are starting up.
Replace cfgCommandTotal()/cfgOptionTotal() functions with constants. The constants are applicable in more cases and allow the compiler to optimize certain loops more efficiently.

IMPORTANT NOTE: In prior releases it was possible to specify options on the command-line that were invalid for the current command without getting an error. An error will now be generated for invalid options so it is important to carefully check command-line options in your environment to prevent disruption.
Fixed an issue where options that were invalid for the specified command could be provided on the command-line without generating an error. The options were ignored and did not cause any change in behavior, but it did lead to some confusion. Invalid options will now generate an error.
Fixed an issue where internal symlinks were not being created for tablespaces in the repository. This issue was only apparent when trying to bring up clusters in-place manually using filesystem snapshots and did not affect normal backup and restore.
Fixed an issue that prevented errors from being output to the console before the logging system was initialized, i.e. while parsing options. Error codes were still being returned accurately so this would not have made a process look like it succeeded when it did not.

Improved handling of users/groups captured during backup that do not exist on the restore host. Also explicitly handle the case where user/group is not mapped to a name.
Option handling is now far more strict. Previously it was possible for a command to use an option that was not explicitly assigned to it. This was especially true for the
The pg_xlogfile_name() function is no longer used to construct WAL filenames from LSNs. While this function is convenient it is not available on a standby. Instead, the archive is searched for the LSN in order to find the timeline. If due to some misadventure the LSN appears on multiple timelines then an error will be thrown, whereas before this condition would have passed unnoticed.

The change log was the last piece of documentation to be rendered in Markdown only. Wrote a converter so the document can be output by the standard renderers. The change log will now be located on the website and has been renamed to Releases
.
Added an execution cache so that documentation can be generated without setting up the full container environment. This is useful for packaging, keeps the documentation consistent for a release, and speeds up generation when no changes are made in the execution list.
Remove function constants and pass strings directly to logDebugParam(). The function names were only used once so creating constants for them was wasteful.
Lists can now be used outside of

Added Ubuntu 16.04 (Xenial) and Debian 8 (Jessie) to the regression suite.
Upgraded doc/test VM to Ubuntu 16.04. This will help catch Perl errors in the doc code since it is not run across multiple distributions like the core and test code. It is also to be hoped that a newer kernel will make Docker more stable.

Added vagrant test configurations for Ubuntu 14.04 and CentOS 7.
Removed dependency on CPAN packages for multi-threaded operation. While it might not be a bad idea to update the threads and Thread::Queue packages, it is no longer necessary.
Modified wait backoff to use a Fibonacci rather than geometric sequence. This will make wait time grow less aggressively while still giving reasonable values.
Added vagrant test configurations for Ubuntu 12.04 and CentOS 6.
More options for regression tests and improved code to run in a variety of environments.

Better resume support. Resumed files are checked to be sure they have not been modified and the manifest is saved more often to preserve checksums as the backup progresses. More unit tests to verify each resume case.
Resume is now optional. Use the
More info messages during restore. Previously, most of the restore messages were debug level so not a lot was output in the log.
Added
Fixed a buffering error that could occur on large, highly-compressible files when copying to an uncompressed remote destination. The error was detected in the decompression code and resulted in a failed backup rather than corruption so it should not affect successful backups made with previous versions.
Pushing duplicate WAL now generates an error. This worked before only if checksums were disabled.
Database System IDs are used to make sure that all WAL in an archive matches up. This should help prevent misconfigurations that send WAL from multiple clusters to the same archive.
Improved threading model by starting threads early and terminating them late.
Regression tests working back to
Fixed broken checksums and now they work with normal and resumed backups. Finally realized that checksums and checksum deltas should be functionally separated and this simplified a number of things. Issue #28 has been created for checksum deltas.
Fixed an issue where a backup could be resumed from an aborted backup that didn't have the same type and prior backup.
Added restore functionality.

Fairly comprehensive unit tests for all the basic operations. More work to be done here for sure, but then there is always more work to be done on unit tests.
Found and squashed a nasty bug where file_copy() was defaulted to ignore errors. There was also an issue in file_exists() that was causing the test to fail when the file actually did exist. Together they could have resulted in a corrupt backup with no errors, though it is very unlikely.
Worked on improving error handling in the File object. This is not complete, but works well enough to find a few errors that have been causing us problems (notably, find is occasionally failing building the archive async manifest when system is under load).
The
If an archive directory which should be empty could not be deleted backrest was throwing an error. There's a good fix for that coming, but for the time being it has been changed to a warning so processing can continue. This was impacting backups as sometimes the final archive file would not get pushed if the first archive file had been in a different directory (plus some bad luck).

Archiving is single-threaded. This has not posed an issue on our multi-terabyte databases with heavy write volume. Recommend a large WAL volume or to use the async option with a large volume nearby.
Backups are multi-threaded, but the Net::OpenSSH library does not appear to be 100% thread-safe so it will very occasionally lock up on a thread. There is an overall process timeout that resolves this issue by killing the process. Yes, very ugly.
Checksums are lost on any resumed backup. Only the final backup will record checksum on multiple resumes. Checksums from previous backups are correctly recorded and a full backup will reset everything.
The Storable because Config::IniFile does not seem to handle large files well. Would definitely like to save these as human-readable text.
Absolutely no documentation (outside the code). Well, excepting these release notes.
