ec9f23d31f Remove CentOS 6 from tests and documentation.
CentOS6 EOL'd and the mirrors were swiftly deleted, leading to failures in tests and documentation.

Remove CentOS 6 for now to get builds going again with the intention to replace it in the near future with CentOS 8.

417818dcca Add --no-coverage-report to test.pl to disable report generation.
There is no sense in generating detailed coverage reports in CI environments where they will never be seen. It takes time and format differences in some older versions can cause problems in the report generation code.

Note that missing coverage will still be reported on stdout and the test will fail.

f9c86b11a5 More improvements to custom coverage report.
* Fix a few issues with file names being truncated introduced in 787d3fd6.

* Use function line info from the lcov file to calculate which lines to show for uncovered functions.  This is more accurate than what we were doing before and function comment headers are now excluded which reduces clutter in the report.

4328bc1ac6 Move raw coverage results to test/result/raw path.
These results were stored in the vagrant path along with a full copy of src.

Instead store the raw coverage data in test/result/raw and change source references to the files that already exist in [test-path]/repo.

d702249507 Build binaries in the test path rather than the vagrant path.
It makes more sense to build in the test path since many developers won't have a vagrant path. Anyway, it's better not to modify the vagrant path since it belongs to vagrant.

Instead of installing the binary just mount it into the container from where it was built. This saves a bit of time and space.

0f7fe55f72 Build packages on demand only and change build path.
Building packages is not a normal part of development so don't build packages by default. Instead build them in CI as needed.

Do the builds in test/result instead of .vagrant to be friendlier with hosts that are not running vagrant. Anyway, it's probably not a good idea to be creating files in the .vagrant path.

237a3da4d6 Configure and make improvements.
Configure:

* Use standard make variables, e.g. CFLAGS, rather than our own, e.g. CINCLUDE
* Add PG_CONFIG var for configuring custom pg_config location
* Don't error if xml_config or pg_config is missing (but error if libs/headers not found)
* Check for zlib.h header
* Check for lz4frame.h header when liblz4 is present

Make:

* Use gcc-style auto dependencies
* Put src list at the top since it is most frequently modified
* Add clean-all target to also remove auto-generated config files

0ba8062f5f Get package source files dynamically during package build.
The prior method was to build a special container to hold these files which meant they would get stale on development systems.  On CI the container was always rebuilt so failures would be seen there even when dev seemed to be working.

Instead get the package source when the package is built to ensure it is as up-to-date as possible.

This change was prompted by failures on the Ubuntu 12.04 container while getting the package source, probably due to an ancient version of git.  Package builds are no longer supported on that platform with the addition of lz4 compression so it didn't seem worth fixing.

4a5bd002c0 Move pgBackRest::Version module to pgBackRestDoc::ProjectInfo.
The primary source for project info is now src/version.h.

The pgBackRestDoc::ProjectInfo module loads the project info from src/version.h at runtime so there is no need to update it.

731b862e6f Rename BackRestDoc Perl module to pgBackRestDoc.
This is consistent with the way BackRest and BackRest test were renamed way back in 18fd2523.

More modules will be moving to pgBackRestDoc soon so renaming now reduces churn later.

36d4ab9bff Move Perl modules out of lib directory.
This directory was once the home of the production Perl code but since f0ef73db this is no longer true.

Move the modules to test in most cases, except where the module is expected to be useful for the doc engine beyond the expected lifetime of the Perl test code (about a year if all goes well).

The exception is pgBackRest::Version which requires more work to migrate since it is used to track pgBackRest versions.

79cfd3aebf Remove LibC.
This was the interface between Perl and C introduced in 36a5349b but since f0ef73db has only been used by the Perl integration tests.  This is expensive code to maintain just for testing.

The main dependency was the interface to storage, no matter where it was located, e.g. S3.  Replace this with the new-introduced repo commands (d3c83453) that allow access to repo storage via the command line.

The other dependency was on various cfgOption* functions and CFGOPT_ constants that were convenient but not necessary.  Replace these with hard-coded strings in most places and create new constants for commonly used values.

Remove all auto-generated Perl code.  This means that the error list will no longer be maintained automatically so copy used errors to Common::Exception.pm.  This file will need to be maintained manually going forward but there is not likely to be much churn as the Perl integration tests are being retired.

Update test.pl and related code to remove LibC builds.

Ding, dong, LibC is dead.

3796b74dca Use stock PostgreSQL page checksum implementation.
We were using a customized version which worked fine but was hard to merge with upstream changes.  Now this code is maintained much like the types in static.auto.h that we copy and check with each release.

The goal is to eventually build directly against PostgreSQL (either source or libcommon) and this brings us one step closer.

977ec2e307 Integration test improvements for disk and memory efficiency.
Set log-level-file=off when more that one test will run.  In this case is it impossible to see the logs anyway since they will be automatically cleaned up after the test.  This improves performance pretty dramatically since trace-level logging is expensive.  If a singe integration test is run then log-level-file is trace by default but can be changed with the --log-level-test-file option.

Reduce buffer-size to 64k to save memory during testing and allow more processes to run in parallel.

Update log replacement rules so that these options can change without affecting expect logs.

f0ef73db70 pgBackRest is now pure C.
Remove embedded Perl from the distributed binary.  This includes code, configure, Makefile, and packages.  The distributed binary is now pure C.

Remove storagePathEnforceSet() from the C Storage object which allowed Perl to write outside of the storage base directory.  Update mock/all and real/all integration tests to use storageLocal() where they were violating this rule.

Remove "c" option that allowed the remote to tell if it was being called from C or Perl.

Code to convert options to JSON for passing to Perl (perl/config.c) has been moved to LibC since it is still required for Perl integration tests.

Update build and installation instructions in the user guide.

Remove all Perl unit tests.

Remove obsolete Perl code.  In particular this included all the Perl protocol code which required modifications to the Perl storage, manifest, and db objects that are still required for integration testing but only run locally.  Any remaining Perl code is required for testing, documentation, or code generation.

Rename perlReq to binReq in define.yaml to indicate that the binary is required for a test.  This had been the actual meaning for quite some time but the key was never renamed.

11c7c8fabb Remove pgbackrest test user.
This user was created before we tested in containers to ensure isolation between the pg and repo hosts which were then just directories.  The downside is that this resulted in a lot of sudos to set the pgbackrest user and to remove files which did not belong to the main test user.

Containers provide isolation without needing separate users so we can now safely remove the pgbackrest user.  This allows us to remove most sudos, except where they are explicitly needed in tests.

While we're at it, remove the code that installed the Perl C library (which also required sudo) and simply add the build path to @INC instead.

642ce003c8 Don't autogenerate embedded libc code by default.
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.

Suggested by Stephen Frost.

45881c74ae Allow most unit tests to run outside of a container.
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.

f1ba428fb0 Add performance test capability in C with scaling.
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.

9836578520 Remove perl critic and coverage.
No new Perl code is being developed, so these tools are just taking up time and making migrations to newer platforms harder.  There are only a few Perl tests remaining with full coverage so the coverage tool does not warn of loss of coverage in most cases.

Remove both tools and associated libraries.

0a96a2895d Add storage layer for tests and documentation.
The tests and documentation have been using the core storage layer but soon that will depend entirely on the C library, creating a bootstrap problem (i.e. the storage layer will be needed to build the C library).

Create a simplified Posix storage layer to be used by documentation and the parts of the test code that build and execute the actual tests.  The actual tests will still use the core storage driver so they can interact with any type of storage.

027c263871 Add configure script for improved multi-platform support.
Use autoconf to provide a basic configure script. WITH_BACKTRACE is yet to be migrated to configure and the unit tests still use a custom Makefile.

Each C file must include "build.auto.conf" before all other includes and defines.  This is enforced by test.pl for includes, but it won't detect incorrect define ordering.

Update packages to call configure and use standard flags to pass options.

18b62a4220 Only run test-level stack trace by default for unit-tested modules.
This amends 70c30dfb which disabled test tracing in general.

Instead, only enable test tracing by default for modules that are being unit tested. This saves lots of time but still ensures that test tracing is working and helps with debugging in unit tests.

Also rename the option to --debug-test-trace for a clarity.

70c30dfb61 Disable test-level stack trace by default.
Detailed stack traces for low-level functions (e.g. strCat, bufMove) can be very useful for debugging but leaving them on for all tests has become quite burdensome in terms of time.  Complex operations like generating JSON on a large KevValue can lead to timeouts even with generous values.

Add a new param, --debug-trace, to enable test-level stack trace, but leave it off by default.

22ecbc153a New, concise coverage report for C.
The report HTML generated by lcov is overly verbose and cumbersome to navigate. Since we maintain 100% coverage it's far more interesting to look at what is not covered than what is.

Deleted files are showing up in git ls-files (added 57d78092) but they don't actually exist on disk.

57d7809297 Improve efficiency of code generation.
Code generation saved files even when they had not changed, which often caused code generation cascades. So, don't save files unless they have changed.

Use rsync to determine which files have changed since the last test run. The manifest of changed files is saved and not removed until all code generation and builds have completed. If an error occurs the work will be redone on the next run.

The eventual goal is to do all the builds from the test/repo directory created by rsync but for now it is only used to track changes.

7794ab50dc Preserve contents of C unit test build directory between test.pl executions.
The contents were already preserved between tests in a single test.pl run but for a separate execution the entire project had to be built from scratch, which was getting slower as we added code.

1a98bd41b4 Mount tmpfs in Vagrantfile instead test.pl.
Mounting/unmounting tmpfs on /home/[user]/test takes time, forces at least 3GB of memory to be available for tests, and makes it harder to preserve data between tests.

Instead, move mounting of tmpfs to the Vagrantfile and add it to fstab so it survives reboots.

07f38f584a Use lcov for C unit test coverage reporting.
Switch from Devel::Cover because it would not report on branch coverage for reports converted from gcov.

Branch coverage is not complete, so for the time being errors will only be generated when statement coverage is not complete. Coverage of unit tests is not displayed in the report unless they are incomplete for either statement or branch coverage.

5f2884cb29 Suppress coverage failures for Archive/Push/Async on Travis.
The coverage report shows some code as never being run -- but that makes no sense because the tests pass.  This may be due to trying to combine the C and Perl coverage reports and overwriting some runs.

Suppress for now with a plan to implement LCOV for the C unit tests.
