It is better to clear errors after the catch block completes rather than leave them set until the next error. This also make is possible to tell when a error is currently being handled, which a function further down the stack might use to modify its behavior. Currently this is only useful in testing, but clearing the error seems like a good idea in general.
Two places used errors outside the CATCH() block. Mem context cleanup now uses a FINALLY() which is a better implementation anyway. The error handling in main() now calls exitSafe() from withing the CATCH() block.
Add StringList, which is not a primitive type but rather an array of String types.
Also update pckWriteToLog() to work after pckWriteEnd(), i.e. this->tagStackTop is NULL.
Move a PackRead or PackWrite object to a new mem context.
Also note that these functions may not work as expected with pack objects created by pckReadNewBuf() and pckWriteNewBuf() since the pack object does not have ownership of the passed buffer and cannot move it.
The hrnErrorThrowP() macro allows errors with specified fields to be generated, which simplifies testing.
Update the common/exit test to use the new macro.
Azurite, which is used for testing, did not enforce this before so the capital letters were not a problem. Now Azurite enforces the same rules as Azure so use lower-case identifiers instead.
These names were only used in integration tests so there was no production impact.
This allows TEST_STORAGE_EXISTS() to be used in most cases where TEST_STORAGE_REMOVE() was used before.
Rename TEST_STORAGE_REMOVE() to HRN_STORAGE_REMOVE() now that is is no longer used as a test. Still allow an error when the file is missing just to help keep tests tidy.
Since the pack type was stored in 4 bits, only 15 values were allowed (0 was reserved).
Allow virtually unlimited types by storing type info in a base-128 encoded integer following the tag when the type bits in the tag are set to 0xF.
Also separate the type IDs used in the pack (PackTypeMap) from those presented to the user (PackType). The prior PackType enum exposed implementation details to the user, e.g. pckTypeUnknown.
The functions were named with short integer representations (e.g. I32) but the param structs were using longer ones, e.g. UInt32. Shorten the integer representations in the param structs to match.
Also rename pckReadUInt64Internal() to pckReadU64Internal() for the same reason.
The pg storage must be started before the repo storage to set the max remotes allowed to 2. The protocol helper expects all remotes to have the same type so we are cheating here a bit, but without this ordering the second remote will never be sent an explicit exit and may not save coverage data.
At one time there was a lot more in this header but it got merged with the enums and constants in config.auto.c, leaving only the ConfigOptionType enum.
Auto-generating the ConfigOptionType enum is not very useful since new option types require code in parse.c.

HRN_CFG_LOAD() handles the majority of test configuration loads and has various options for special cases.
It was not clear when to use harnessCfgLoadRaw() vs harnessCfgLoad(). Now "raw" functionality is granular and enabled by parameters, e.g. noStd.
Make the macros more consistent in format and make sure that each macro outputs a line number before doing any work so when errors happen it is clear where they happened.
Add noRecurse option to TEST_STORAGE_LIST().
Add comment option to all storage macros.
Instead store the line number in hrnTestLogPrefix() so it doesn't need to be passed to hrnTestResultBegin().
Also add missing linefeed in hrnStorageList().
All instances of storageTest are better represented with storagePg*(), which allows TEST_PATH and TEST_PATH_PG to be omitted.
Also remove some headers which are no longer needed.
The default is to keep all backup history to match the current behavior. In minimal configuration (0 days), unexpired backups are always kept in history.
When a full backup manifest expires, all dependent differential/incremental manifests expire as well.
Run the remote process inside a forked child process instead of exec'ing it. This allows coverage to accumulate in the remote process rather than needing to test the remote protocol functions directly, resulting in better end-to-end testing and less test duplication. Another advantage is that the pgbackrest binary does not need to be built for the test and the test does not need to run in a container.
This allows protocolRemoteExec() to be shimmed, which means the remote can be run as a child of the test process, simplifying coverage testing.
The shim does not need SSH parameters, so also split those out into a separate function and update the tests to match.
Add executable to parameter list to avoid first option being lost. The backup, restore, and verify tests worked OK with their first option being defaulted because it ended up being job-retry which worked fine as the default.
Add hrnProtocolLocalShimUninstall() allow the shim to be uninstalled.
Log shim at debug level to make it obvious in the logs when a shim is in use.
There are no code changes from PostgreSQL 13 so simply add the new version.
Add CATALOG_VERSION_NO_MAX to allow the catalog version to "float" during the PostgreSQL beta/rc period so new pgBackRest versions are not required when the catalog version changes.
Update the integration tests to handle new PostgreSQL startup messages.
manifestLinkCheck() was pretty inefficient so large numbers of links caused it to use a lot of memory and eventually crash. This is a more efficient implementation which runs O(nlogn) and uses far less memory.
Checking for duplicate file links has been added, which represents a change in behavior, but hopefully a good one.
The user guide was split primarily to provide documentation for the stop-auto option in PostgreSQL <= 9.5. Now that 9.5 is EOL there does not seem to be a good reason to generate an extra user guide. The stop-auto function is still documented in the reference.
Leave the stop-auto documentation in the user guide in case we want to manually generate documentation for older versions.
Also rename centos to rhel for most identifiers since that is the core platform we are building for, similar to how we label 'debian' builds even though we generally use Ubuntu. With CentOS set to become an upstream for RHEL later this year, we'll likely need to pick a new test distribution, perhaps Rocky Linux if that gets off the ground.
