Test points are not supported by the new C code so these will be replaced with unit tests.
The fact that the tests still pass even when the changes aren't made mid-backup (except application_name) shows how weak they were in the first place.
Even so, this does represent a regression in (soon to be be removed) Perl coverage.
Test points will not be available in the C code so update these tests as best as possible without using them.
This represents a loss of coverage for the Perl code (soon to be removed) which will be made up in the C code with unit tests.
These tests require test points which are not being implemented in the C code.
This functionality is fully tested in the command/control unit tests so integration tests are no longer required.
This expression determines which files contain page checksums but it was also including the directory above the relation directories. In a real PostgreSQL installation this not a problem because these directories don't contain any files.
However, our tests place a file in `base` which the Perl code thought should have page checksums while the new C code says no.
Update the expression to document the change and avoid churn in the expect logs later.
Installing lcov 1.14 everywhere turned out to be a problem just as using 1.13 on Ubuntu 19.04 was.
Since we primarily use Ubuntu 18.04 for coverage testing and reporting, we definitely want to make sure that works. So, revert to using the default packaged lcov except when specified otherwise in VmTest.pm.
PostgreSQL minor version releases are also included since all containers have been rebuilt.
The issue "fixed" in f01aa586 was caused by treating all strings as format strings while logging, which was fixed in 0c05df45.
Revert because there no longer seems a reason for the extra logic, and it was only partially applied, i.e. not to env vars, command-line options, or config options.
Using the same macros for formatted and unformatted logging had several disadvantages.
First, the compiler was unable to verify the format string against the parameters.
Second, legitimate % characters in messages were being interpreted as format characters with garbage output ensuing.
Add _FMT() variants and update all call sites to use the correct variant.
This character causes problems in C and in the shell if we try to output it in an error message.
Forbid it completely and spell it out in error messages to avoid strange effects.
There is likely a better way deal with the issue but this will do for now.
The protocol timeout tests have been superceded by unit tests.
The TEST_BACKUP_RESUME test point was incorrectly included into a number of tests, probably a copy pasto. It didn't hurt anything but it did add 200ms to each test where it appeared.
Catalog and control version tests were redundant. The database version and system id tests covered the important code paths and the C code gets these values from a lookup table.
Finally, fix an incomplete update to the backup.info file while munging for tests.
It is occasionally useful to get information about a file outside of the base storage path. storageLocal() can be used in some cases but when the storage is remote is doesn't seem worth creating a separate storage object for adhoc info requests.
storageInfo() is a read-only operation so this seems pretty safe. The noPathEnforce parameter will make auditing exceptions easy.
The ability to disable enforcement (i.e., the requested absolute path is within the storage path) globally will be removed after the Perl migration.
The feature will still be needed occasionally so allow it in an adhoc fashion.
A . in a link will always lead to an error since the destination will be inside PGDATA. However, it is accepted symlink syntax so it's better to resolve it and get the correct error message.
Also, we may have other uses for this function in the future.
Adding a dummy column which is always set by the P() macro allows a single macro to be used for parameters or no parameters without violating C's prohibition on the {} initializer.
-Wmissing-field-initializers remains disabled because it still gives wildly different results between versions of gcc.
It wasn't practical for the main process to be ignorant of the remote path, and in any case knowing the path makes debugging easier.
Pull the remote path when connecting and pass the result of local storagePath() to the remote when making calls.
Pushing output through a JSON blob is not practical if the output is extremely large, e.g. a backup manifest with 100K+ files.
Add read/write routines so that output can be returned in chunks but errors will still be detected.
Previously, options were being filtered based on what was currently valid. For chained commands (e.g. backup then expire) some options may be valid for the first command but not the second.
Filter based on the command definition rather than what is currently valid to avoid logging options that are not valid for subsequent commands. This reduces the number of options logged and will hopefully help avoid confusion and expect log churn.
Bug Fixes:
* Fix remote timeout in delta restore. When performing a delta restore on a largely unchanged cluster the remote could timeout if no files were fetched from the repository within protocol-timeout. Add keep-alives to prevent remote timeout. (Reported by James Sewell, Jens Wilke.)
* Fix handling of repeated HTTP headers. When HTTP headers are repeated they should be considered equivalent to a single comma-separated header rather than generating an error, which was the prior behavior. (Reported by donicrosby.)
Improvements:
* JSON output from the info command is no longer pretty-printed. Monitoring systems can more easily ingest the JSON without linefeeds. External tools such as jq can be used to pretty-print if desired. (Contributed by Cynthia Shang.)
* The check command is implemented entirely in C. (Contributed by Cynthia Shang.)
Documentation Improvements:
* Document how to contribute to pgBackRest. (Contributed by Cynthia Shang.)
* Document maximum version for auto-stop option. (Contributed by Brad Nicholson.)
Test Suite Improvements:
* Fix container test path being used when --vm=none. (Suggested by Stephen Frost.)
* Fix mismatched timezone in expect test. (Suggested by Stephen Frost.)
* Don't autogenerate embedded libc code by default. (Suggested by Stephen Frost.)

We had some problems with newer versions so had held off on updating. Those problems appear to have been resolved.
In addition, the --compat flag is no longer required. Prior versions of MinIO required all parts of a multi-part upload (except the last) to be of equal size. The --compat flag was introduced to restore the default S3 behavior. Now --compat is only required when ETag is being used for MD5 verification, which we don't do.
Previously we were using int64_t to debug time_t but this may not be right depending on how the compiler represents time_t, e.g. it could be a float.
Since a mismatch would have caused a compiler error we are not worried that this has actually happened, and anyway the worst case is that the debug log would be wonky.
The primary benefit, aside from correctness, is that it makes choosing a parameter debug type for time_t obvious.
Previously the mock integration tests would be skipped for VMs other than the standard four used in CI. Now VMs outside the standard four will run the same tests as VM4 (currently U18).
Using pg1-path, as we were doing previously, could lead to WAL being copied to/from unexpected places. PostgreSQL sets the current working directory to PGDATA so we can use that to resolve relative paths.
This makes configuring tests easier.
Also add a parameter for tests that require sudo. This should be retired at some point but some tests still require it.
This will likely improve performance, but it also makes the filesystem consistent between platforms.
A number of tests were failing on shiftfs, which was the default for arm64 on Travis.
