The error handler used a loop to process try, catch, and finally blocks. This worked fine but static analysis tools like Coverity did not understand that the finally block would always run and so there were false positives about double-free, unfreed resource, etc.
This implementation removes the loop, which simplifies everything, and makes it clear that the finally block will always run. This cuts down on Coverity false positives.
This implementation also catches lack of coverage on empty catch blocks so a few test fixes were committed separately in d74fe7a.
A small refactor in backup.c is required because gcc 10.3.1 on Fedora 33 complains that the reason variable may be used uninitialized. It's not clear why this is the case, but reducing the scope of the TRY block fixes the issue.
Rather the converting String to StringIds at runtime, store defaults in StringId format in parse.auto.c and convert user input to StringId during parsing.
The compress-type, repo-type and log-level-* options have allow lists, which means it is more efficient to treat them as StringIds.
For compress-type and log-level-* also update the functions that convert them to enums.
The strIdFrom*() forced the caller to pick an encoding, which led to a number of TRY...CATCH blocks in the code. In practice the caller does not care which encoding is used as long as the string is valid for some encoding.
Update the strIdFrom*() function to try all possible encodings and only throw an error when the string is not valid for any of them.

The new rendering behavior is correct in normal cases, but for the pre-rendered HTML blocks in the command and configuration references it causes a lot of churn. This would be OK if the new HTML was diff-able, but it is not.
Go back to the old behavior of using br tags for this case to reduce churn until a more permanent solution is found.
Since CentOS 8 will be EOL at the end of the year it makes sense to do this now. The centos:8 image is still used in documentation.xml because changes there require manual testing, which will need to be done at a later date. The changes are not user-facing, however, and can be done at any time.
Also update CentOS references to RHEL since that is what we are emulating for testing purposes.
Currently empty CATCH() blocks are always marked as covered because of the loop structure of error handling.
A prototype implementation of error handling without looping has shown that these CATCH() blocks are not covered without new tests. Whether or not that prototype gets committed it is worth adding the tests.
This is mostly to revert some comment changes in b11ab9f7 that will break the ppc64le patch, but at the same time keep the spelling consistent in all comments and documentation.
Also revert some space changes for the same reason.
Azurite released another breaking change (see fbd018cd, 096829b3, c38d6926, and Azurite issue 1039) so make adjustments as needed to documentation and tests.
Also remove some dead code that hid the repo-storage-host option and was made obsolete by all these changes.
Checking the return value is not terribly important here, but if setsockopt() fails it is likely that bind() will fail as well. May as well get it over with and this makes Coverity happy.
3879bc69 added this call and the parameters were not quite right but in way that the compiler decided they were OK. It was mostly working but TLS verification was disabled if caPath was NULL, which is not OK.
The variants were needed to easily serialize configurations for the Perl code.
Unions are more efficient and will allow us to add new types that are not supported by variants, e.g. StringId.
The text indicates to populate the pg-primary IP address into the pg_hba.conf file to allow replication connections. It should indicate to populate the pg-standby IP address
It is not uncommon for the S3/Azure emulators we use to introduce breaking changes without warning. If that happens the documentation can still be built by specifying a working version of the image. In general, it is better to let the version float so we know when things break.
Azurite has yet another breaking change coming up (see 096829b3, c38d6926, and Azurite issue 1039) so set azure-image at the current version until the breaking change has been released.
These flags are used for all tests but it was not possible to add them to configure before the change in 046d6643. This is especially important for adhoc tests to ensure the flags are not forgotten.
Remove the flags from test make commands where they were being applied.
There is no change for production builds.
Some flags, e.g. -Wfatal-errors, will cause tests in configure to behave incorrectly so we have not been able to add them to --enable-test.
Add the compiler flags as late as possible so configure checks are not affected. This will allow us to add flags that we need for testing without having to explicitly pass them to make.
The TLS server is an alternative to using SSH for protocol connections to remote hosts.
This command is currently experimental and intended only for trial and testing. As such, the new commands and options will not show up in the command-line help unless directly requested.
Some tests can generate very large error messages for diffs and they often get cut off before the end.
Also fix a test so it does not create too large a buffer on the stack.
The previous format was custom for configuration parsing and was not as expressive as the pack format. An immediate benefit is that commands with the same optional rules are merged.
Defaults are now represented correctly (not multiplied), which simplifies the option default functions used by help.
