Coverage of the documentation code is not important enough to report to users. If it were reported it should be in a separate section (along with test code coverage).
The Perl integration tests were migrated as faithfully as possible, but there was some cruft and a few unit tests that it did not make sense to migrate.
Also remove all Perl code made obsolete by this migration.
All unit, performance, and integration tests are now written in C but significant parts of the test harness remain to be migrated.
This allows analysis of coverage failures that only happen in CI. It is not ideal since the report needs to be copied from the log output into an HTML file where it can be viewed, but better than nothing.
Migrate generation of these files from help.xml to the intermediate documentation format. This allows us to share a lot of code that is already in C and remove duplicated code in Perl. More duplicate code can be removed in Perl once man generation is migrated.
Also update the unit test harness to allow testing of modules in the doc directory.
Double spaces have fallen out of favor in recent years because they no longer contribute to readability.
We have been using single spaces and editing related paragraphs for some time, but now it seems best to update the remaining instances to avoid churn in unrelated commits and to make it clearer what spacing contributors should use.
When this code was migrated to C the unit tests were not included because there were more important priorities at the time.
This also requires some adjustments to coverage because of the new code location.
Both have newer gcc and OpenSSL 3.
Fedora 36 runs horribly slow with valgrind enabled so run the valgrind tests on Ubuntu 22.04. Fedora 36 has a newer gcc so it is still worth testing on.
These files were never intended to be compiled on their own so the .c extension was a bit misleading. In particular Meson does not like .c files that are not intended to be compiled independently.
Leave header files as is since they are already protected against being included more than once and are never expected to be compiled.
A CHECK() worked exactly like ASSERT() except that it was compiled into production code. However, over time many checks have been added that should not throw AssertError, which should be reserved for probable coding errors.
Allow the error code to be specified so other error types can be thrown. Also add a human-readable message since many of these could be seen by users even when there is no coding error.
Update coverage exceptions for CHECK() to match ASSERT() since all conditions will never be covered.
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.
These tests required sudo to achieve complete coverage.
Add a new coverage exception, vm_covered, that applies to code that can only be covered in a container. When the test is run outside of a container code sections that require a container will be excluded with TEST_CONTAINER_REQUIRED and the coverage exception will be added to prevent a coverage error.
This does require marking up the core code with vm_covered, which in some modules (e.g. common/io/tls/client) can be extensive. It's possible that some of these tests can be rewritten to be less dependent on sudo but no attempt was made to do that here.
Only allow coverage summaries in a vm since coverage summaries outside a vm will not be complete, which was true even before this commit.
* 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.
* Show all uncovered branch parts even when there are more than two parts per branch. This is the way gcc9 reports coverage so it needs to work even if it doesn't make as much sense as the old way.
* Show covered branches in functions where coverage is missing. Showing just the uncovered branches can be confusing because it's not always clear how the coverage relates to the code. By showing all branch coverage (+ or -) this correspondence is made easier.
We don't report branch coverage on test modules (e.g. test/src/module/common/errorTest.c) but the code that excluded branch coverage from the test module would also exclude it from all core modules if the test module was included in the lcov report due to lack of function/line coverage.
Adjust the coverage code to only exclude branches during the extraction of test module coverage.
When multiple files were missing coverage it could be hard to locate the coverage report for a specific file.
Add links for uncovered files to make this easier.
Also move table titles out of the table so they are valid html.
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.
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.
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.
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.
This report replaces the lcov report that was generated manually for each release.
The lcov report was overly verbose just to say that we have virtually 100% coverage.
If the last } of a function was marked as uncovered then the context selection would overrun into the next function.
Start checking context on the current line to prevent this. Make the same change for start context even though it doesn't seem to have an issue.
Too few lines were shown for coverage context so show the entire function if it has any missing coverage.
Update colors to work with light and dark browser modes.
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.
The new report presents all missing coverage on a single page and excludes code that is covered for brevity.
