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The protocol timeout tests have been superceded by unit tests.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.
Using a designated initializer is safer than zeroing the struct. It is also better for debugging because Valgrind should be able to detect access to areas that are not initialized due to alignment.
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.
This should have been removed when the support for the option was removed in c7333190.
The option cannot be removed entirely because we don't want to error in the case where --force was specified but the stanza is valid.
Many functions don't take optional parameters, so tacking the struct onto the end was pretty burdensome.
Add macros to get the interface under a variety of circumstances to make this practical.
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.)
