This test was not creating recovery.signal when testing with --type=preserve. The preserve recovery type only keeps existing files and does not create any.
RC1 was just ignoring recovery.signal and going right into recovery. Weirdly, 12.0 used restore_command to do crash recovery which made the problem harder to diagnose, but this has now been fixed in PostgreSQL and should be released in 12.1.
Mark all pre commands as skip so they won't be run again after the container is built.
Ensure that pre commands added to the container are run as the container user if they are not intended to run as root.
This is only needed when new code is added to the Perl C library, which is becoming rare as the migration progresses.
Also, the code will vary slightly based on the Perl version used for generation so for normal users it is just noise.

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.

A number of tests have been updated and Fedora 30 has been added to the test suite so the unit tests can run on gcc 9.
Stop running unit tests on co6/7 since we appear to have ample unit test coverage.
This tool was only being used it a few places but was a pretty large dependency.
Rework the forceStorageMove() code using our storage layer and replace one aws cli cp with a storage put.
Also, remove the Dockerfile that was once used to build the Scality S3 test container.
Because db can be reset to NULL on an error in the try block we need nested try blocks to ensure that db is non-NULL and can be freed on an error after being created.
This is not a production issue because the db will be freed when the temp mem context is freed, but it does affect reproducibility in the tests and is a bit tidier.
Now that our tests are more diversified it makes sense to load only the packages that are needed for each test.
Move the package loads from .travis.yaml to test/travis.pl where we have more control over what is loaded.
Note that building the manifest on each host has been temporarily removed.
This feature will likely be brought back as a non-default option (after the manifest code has been fully migrated to C) since it can be fairly expensive.
Check the backup.info file against the backup path. Add any backups that are missing and remove any backups that no longer exist.
It's important to run this before backup or expire to be sure we are using the most up-to-date list of backups.
Three major changes were required to get this working:
1) Provide the path to pgbackrest in the build directory when running outside a container. Tests in a container will continue to install and run against /usr/bin/pgbackrest.
1) Set a per-test lock path so tests don't conflict on the default /tmp/pgbackrest path. Also set a per-test log-path while we are at it.
2) Use localhost instead of a custom host for TLS test connections. Tests in containers will continue to update /etc/hosts and use the custom host.
Add infrastructure and update harnessCfgLoad*() to get the correct exe and paths loaded for testing.
Since new tests are required to verify that running outside a container works, also rework the tests in Travis CI to provide coverage within a reasonable amount of time. Mainly, break up to doc tests by VM and run an abbreviated unit test suite on co6 and co7.
Features:
* PostgreSQL 12 support.
* Add info command set option for detailed text output. The additional details include databases that can be used for selective restore and a list of tablespaces and symlinks with their default destinations. (Contributed by Cynthia Shang. Suggested by Stephen Frost, ejberdecia.)
* Add standby restore type. This restore type automatically adds standby_mode=on to recovery.conf for PostgreSQL < 12 and creates standby.signal for PostgreSQL ≥ 12, creating a common interface between PostgreSQL versions. (Reviewed by Cynthia Shang.)
Improvements:
* The restore command is implemented entirely in C. (Reviewed by Cynthia Shang.)
Documentation Improvements:
* Document the relationship between db-timeout and protocol-timeout. (Contributed by Cynthia Shang. Suggested by James Chanco Jr.)
* Add documentation clarifications regarding standby repositories. (Contributed by Cynthia Shang.)
* Add FAQ for time-based Point-in-Time Recovery. (Contributed by Cynthia Shang.)
Recovery settings are now written into postgresql.auto.conf instead of recovery.conf. Existing recovery_target* settings will be commented out to help avoid conflicts.
A comment is added before recovery settings to identify them as written by pgBackRest since it is unclear how, in general, old settings will be removed.
recovery.signal and standby.signal are automatically created based on the recovery settings.
The additional details include databases that can be used for selective restore and a list of tablespaces and symlinks with their default destinations.
This information is not included in the JSON output because it requires reading the manifest which is too IO intensive to do for all manifests. We plan to include this information for JSON in a future release.
Most of these lists should be quite small with the exception of the list in get.c, but it doesn't cost much to sort them and may help in corner cases we have not thought of.
Scaling allows the starting values to be increased from the command-line without code changes.
Also suppress valgrind and assertions when running performance testing. Optimization is left at -O0 because we should not be depending on compiler optimizations to make our code performant, and it makes profiling more informative.
bsearch() is far more efficient than an iterative approach except in the most trivial cases.
For now insert will reset the sort order to none and the list will need to be resorted before bsearch() can be used. This is necessary because item pointers are not stable after a sort, i.e. they can move around. Until lists are stable it's not a good idea to surprise the caller by mixing up their pointers on insert.
PostgreSQL 12 will shutdown in these cases which seems to be the correct action (according to the documentation) when hot_standby = off, but older versions are promoting instead. Set target_action explicitly so all versions will behave the same way.
This does beg the question of whether the PostgreSQL 12 behavior is wrong (though it matches the docs) or the previous versions are.
