However, this could happen if there were host settings on the remote host, which ended badly with lock errors, loops, etc.\r\n\r\nAdd pg-local and repo-local options to indicate that the resource is local even if there are host settings.\r\n\r\nNote that for the time being these options are internal and not intended for general usage. However, this is likely the direction needed to allow for more symmetric and manageable configurations."

        "body": "The prior default was determined by benchmarking the Perl code prior to the 1.0 release. In general buffer allocation was more expensive in Perl so large buffers gave the best performance. This was due to multiple buffer allocations for each filter in an IO operation.\n\nThe C code allocates fixed buffers for each IO operation so the cost for buffer allocation is lower than Perl. That being the case it made sense to benchmark the C code to determine the optimal buffer default.\n\nThe performance/storage tests were used to measure the performance of a variety of filters. 1GiB of data was processed by each filter 10 times and the results of the tests were averaged.\n\nWhile most buffer sizes gave similar performance, 1MiB appeared to perform the best overall. Of course, different architectures are likely to yield different results but this seems like a sensible default.

Using this method, a full backup can be expired only if the time the backup completed is older than the number of days set with repo-retention-full (calculated from the moment the 'expire' command is run) and at least one full backup meets the retention period. If archive retention has not been configured, then the default settings will expire archives that are prior to the oldest retained full backup. For example, if there are three full backups ending in times that are 25 days old (F1), 20 days old (F2) and 10 days old (F3), then if the full retention period is 15 days, then only F1 will be expired; F2 will be retained because F1 is not at least 15 days old."

However, this has caused problems for some users in the past (because they needed the WAL for other purposes) and with the new adhoc and time-based retention features, it was decided that the archives should remain until the threshold was met. The archives will eventually be removed and if having them causes space issues, the expire command and the retention-archive can always be run and adjusted."

Since we were unable to reproduce the issue in a development environment we can only speculate as to the cause, but there is a good chance that blocking sockets were the issue or contributed to the issue.\n\nSo move to a non-blocking implementation to hopefully clear up these issues. Testing in production environments that were prone to locking shows that the approach is promising and at the very least not a regression.\n\nThe main differences from the blocking version are the non-blocking connect() implementation and handling of WANT_READ/WANT_WRITE retries for all SSL*() functions.\n\nTimeouts in the tests needed to be increased because socket connect() and TLS SSL_connect() were not included in the timeout before. The tests don't run any slower, though. In fact, all platforms but Ubuntu 12.04 worked fine with the shorter timeouts."

The storageList() and storageInfoList() functions remain in the storage interface since they are useful -- the only change is simplifying the drivers with no external impact.\n\nNote that since list() accepted an expression infoList() must now do so.

Doing so can cause compiler mis-optimizations or runtime crashes (by modifying read-only memory). It is only safe to use when the result will not be modified, but API design or language restrictions prevent you from declaring that (e.g. because a function returns both const and non-const variables).\n\nNote that this only works in function scope, not for global variables (it would be nice, but not trivial, to improve that).\n\nUNCONSTIFY() requires static assert which is a feature in its own right."

Normally, the stack is not used for this purpose and pushing/popping is a cheap operation. In the prior implementation most of the TRY...CATCH logic needed to be run even on success.\n\nOne bonus is that the binary is about 8% smaller after this change.  Another benefit is that new contexts *must* be explicitly freed/discarded or an error will occur.  See info/manifest.c for an example of where this is useful outside the standard macros."

This is probably only possible if the async process exits immediately, perhaps due to a chdir() failure. Set SIGCHLD back to default in the async process so waitpid() will work as expected.\n\nAlso update the comment on chdir() to more accurately reflect what is happening.\n\nFinally, add a test in certain debug builds to ensure the first fork exits very quickly. This only works when valgrind is not in use because valgrind makes forking so slow that it is hard to tell if the async process performed work or not (in the case that the second fork goes missing and the async process is a direct child)."

If this happened then the backup would error when restored.\n\nThe issue was that removing files from the manifest invalidated the pointers stored in the processing queues.  When a file was removed, all the pointers shifted to the next file in the list, causing a file to be unprocessed.  Since the unprocessed file was still in the manifest it would be saved with no checksum, causing a failure on restore.\n\nWhen process-max was > 1 then the bug would often not express since the file had already been pulled from the queue and updates to the manifest are done by name rather than by pointer."

For instance, NULL == 0 must be true but neither NULL nor 0 must be represented with all zero bits.\n\nInstead use designated initializers to initialize structs.  These guarantee that struct members will be properly initialized even if they are not specified in the initializer.  Note that due to a quirk in the C99 specification at least one member must be explicitly initialized even if it needs to be the default value.\n\nSince pre-zeroed memory is no longer required, adjust memAllocInternal()/memReallocInternal() to return raw memory and update dependent functions accordingly.  All instances of memset() have been removed except in debug/test code where needed.\n\nAdd memNewPtrArray() to allocate an array of pointers and automatically set all pointers to NULL.\n\nRename memGrowRaw() to the more logical memResize()."

This doesn't affect backup integrity but it does prevent clock skew between hosts affecting backup duration reporting.\n\nArchive copy now works as expected when the archive and backup have different compression settings, i.e. when one is compressed and the other is not.

The Perl code tried to set ownership as it was in the manifest even when running as an unprivileged user.  This usually just led to errors and frustration.\n\nThe C code works like this:\n\nIf a restore is run as a non-root user (the typical scenario) then all files restored will belong to the user/group executing pgBackRest. If existing files are not owned by the executing user/group then an error will result if the ownership cannot be updated to the executing user/group. In that case the file ownership will need to be updated by a privileged user before the restore can be retried.\n\nIf a restore is run as the root user then pgBackRest will attempt to recreate the ownership recorded in the manifest when the backup was made. Only user/group names are stored in the manifest so the same names must exist on the restore host for this to work. If the user/group name cannot be found locally then the user/group of the PostgreSQL data directory will be used and finally root if the data directory user/group cannot be mapped to a name."

These functions will be useful in other ways, e.g. generating the tablespace identifier in PostgreSQL >= 9.0."

        "body": "Info files required three copies in memory to be loaded (the original string, an ini representation, and the final info object). Not only was this memory inefficient but the Ini object does sequential scans when searching for keys making large files very slow to load.\n\nThis has not been an issue since archive.info and backup.info are very small, but it becomes a big deal when loading manifests with hundreds of thousands of files.\n\nInstead of holding copies of the data in memory, use a callback to deliver the ini data directly to the object when loading. Use a similar method for save to avoid having an intermediate copy. Save is a bit complex because sections/keys must be written in alpha order or older versions of pgBackRest will not calculate the correct checksum.\n\nAlso move the load retry logic to helper functions rather than embedding it in the Info object. This allows for more flexibility in loading and ensures that stack traces will be available when developing unit tests."

If manifest() was called on a remote it was being decoded into a hash and then immediately re-encoded into JSON for transmission over the protocol layer.\n\nInstead, provide a function for the remote to get the raw JSON which can be transmitted as is and decoded in the calling process instead.\n\nThis makes remote manifest calls as fast as they were before 2.16, but local calls must still pay the decoding penalty and are therefore slower.  This will continue to be true until the Perl storage interface is retired at the end of the C migration.\n\nNote that for reasonable numbers of tables there is no detectable difference.  The case in question involved 250K tables with a 10 minute decode time (which was being doubled) on a fast workstation."

This means than clients could grow if they are not released properly.  The http statistics will hopefully alert us if this is happening."

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.\n\nAlso tweak the coverage rules so that macros without conditionals are automatically excluded from branch coverage as long as they are not themselves a parameter.\n\nFinally, update tests and code where missing coverage was exposed by these changes.

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.\n\nIf logging was enabled (the default) that increased all the file descriptors by one and everything worked.\n\nFix 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."

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.\n\nInstead write a global.error file that applies to any WAL file that does not have an explicit ok or error file.

If this behavior is not desirable then tlsClientClose() may be used to ensure that the next call to tlsClientOpen() will create a new TLS session.\n\nNote that tlsClientRead() is non-blocking unless there are *zero* bytes to be read from the session in which case it will raise an error after the defined timeout. In any case the tlsClientRead()/tlsClientWrite()/tlsClientEof() functions should not generally be called directly.

Both operations require the WAL segment size to properly build a list.\n\nChecking the archive after a backup is still implemented in Perl and has an active database connection, so just get the WAL segment size from the database.\n\nThe archive-get command does not have a connection to the database, so get the WAL segment size from pg_control instead.  This requires a deeper inspection of pg_control than has been done in the past, so it seemed best to copy the relevant data structures from each version of PostgreSQL and build a generic interface layer to address them.  While this approach is a bit verbose, it has the advantage of being relatively simple, and can easily be updated for new versions of PostgreSQL.\n\nSince the integration tests generate pg_control files for testing, teach Perl how to generate files with the correct offsets for both 32-bit and 64-bit architectures."

This allows them to handle secrets because they will not pass values to subprocesses as parameters.  Instead, each subprocess is expected to check the environment directly during configuration parsing.\n\nIn passing, move the error about secrets being passed on the command-line up to command-line parsing and make the error more generic with respect to the configuration file now that multiple configuration files are allowed."

They verified the contents of a table in the (supposedly) restored tablespace, deleted the table, and then deleted the tablespace.  All of this was deemed sufficient to prove that the tablespace had been restored correctly and was valid.\n\nHowever, PostgreSQL will happily recreate a tablespace on the basis of a single full-page write, at least in the affected versions.  Since writes to the test table were replayed from WAL with each recovery, all the tests passed even though the tablespace was missing after the restore.\n\nThe tests have been updated to include direct comparisons against the file system and a new table that is not replayed after a restore because it is created before the backup and never modified again.\n\nVersions ≥ 9.0 were not affected due to numerous synthetic integration tests that verify backups and restores file by file."

The new spool-path option can be used to define a location for queueing WAL segments when archiving asynchronously. Otherwise, a local repository is no longer required.\n\n* Implemented a new config format which should be far simpler to use. See the User Guide and Configuration Reference for details but for a simple configuration all options can now be placed in the stanza section. Options that are shared between stanzas can be placed in the [global] section. More complex configurations can still make use of command sections though this should be a rare use case.\n\n* The default configuration filename is now pgbackrest.conf instead of pg_backrest.conf. This was done for consistency with other naming changes but also to prevent old config files from being loaded accidentally.\n\n* The default repository name was changed from /var/lib/backup to /var/lib/pgbackrest.\n\n* Lock files are now stored in /tmp/pgbackrest by default. These days /run/pgbackrest would be the preferred location but that would require init scripts which are not part of this release. The lock-path option can be used to configure the lock directory.\n\n* Log files are now stored in /var/log/pgbackrest by default and no longer have the date appended so they can be managed with logrotate. The log-path option can be used to configure the lock directory.\n\n* Executable filename changed from pg_backrest to pgbackrest."
