During the bootstrap of PHPUnit we ensure that the database has been
reset to its initial state.
We do this by checking the internally-stored DB write count between
runs. If the count is not yet set (null), or it has been increased, we
force a reset.
When running an isolated test the test runner resets the database, it
then sets up a new isolated test environment by writing a new PHPUnit
test case and passing it to a new PHP Process using standard in. As part
of this, the bootstrap is run for that process.
Because we are in a new process, the db write count is fresh and not yet
set. This has been leading to an additional db reset before the isolated
test.
To handle this we want to _not_ perform a reset during the
initialisation for isolated runs. We know that the DB is in a fresh
state before we start the run.
To support this we need to know whether the test is an isolated test
during the bootstrap, which means we cannot use the previous approach to
calculating this.
Instead we look at the PHP_SELF value. PHP sets this to "Standard input
code" when run from stdin, instead of running a file.
There should not be any other legitimate reason to run a PHPUnit
bootstrap via this stdin approach.
Unfortunately this approach is a little bit risky as it depends on the
presence of a specific string, however this string has been in place
since 2016, and there is no legitimate way of calculating this.
I did consider looking at whether the called script included `/vendor/`
and `/phpunit`, but this is also likely a risky approach if someone
calls PHPUnit in an unexpected way.
This approach is itself unit tested so any change to PHP's stdin string
before we deprecate this approach entirely in 12 months time will be
caught.
Custom autoloaders are deprecated with PHPUnit 9 and will be removed
with PHPUnit 10.
Since PHPUnit 8.5 custom autoloaders don't do much because that
version removed the ability to launch unit tests by class name
and that's exactly the reason we had a custom autoloader (to map
class names to files within our tests). See MDL-67673 about
when direct use of classes was deprecated (8.5), now removed (9.5).
So, as far as it's unused, removing it now, test still can be
selectively using any of:
- a relative path to file (although there are some restrictions comming
with PHPUnit 9, see https://github.com/sebastianbergmann/phpunit/issues/4105
- using --filter, to point to any classname[::method]
- using --testsuite to run a complete suite
- using --config to point to custom components.
Also, commented out the lib/ajax/tests directory because it doesn't
exist / is empty and PHPUnit 9 emits error when a configured test
directory does not exist. See
https://github.com/sebastianbergmann/phpunit/issues/4493.
Alternative was to completely remove the configuration line, but
decided to keep it around in case some day we want to add some
test there.
This includes:
- Changing PHPUnit's bootstrap to use https://www...
- Modify all existing expectations to the new wwwroot.
- Amend some tests now with different defaults because of is_https()
- Added a note to main upgrade.php about the change.
To support PHPUnit we need to support large profiles, these may
include backups and restores. To do that the following was required;
- gzcompress for database space saving.
- gzcompress for XML DomDocument field to say < 10Mb and allow imports.
- Save PHPUnit runs directly to a file so they can be imported to the normal database.
- Memory allowance on profiling view pages increases to support large profiles.
This lets us convert between common office formats. E.g. docx -> pdf
html -> pdf, html -> ods.
This commit also updates assignment editpdf plugin to use this converter
on all compatible submission files.
Rather than setting noemailever in the bootstrap, this sets up a default
phpmailer message sink which will catch all messages.
Tests which require the phpmailer sink will continue to work as before
without change, though the noemailever config setting no longer needs to
be altered.
For tests wanting to test with noemailever set with the previous behaviour,
they will need to load the message sink and then close it.
AMOS BEGIN
MOV ['gspath','assignfeedback_editpdf'],['pathtogs','admin']
MOV ['gspath_help','assignfeedback_editpdf'],['pathtogs_help','admin']
AMOS END
Instead we will create new MUC caches inside each filter plugin.
Please note that all cache filters should work with local caches
without the need of strict cache invalidation.
Improvements include:
* Alternative location might be useful when server administrator wants to maintain
a local copy of component cache instead of using shared $CFG->cachedir.
* Component caching is now enabled in behat tests which should improve performance.
* Standardised ignoring of component caching.
* Fixed debug mode in ABORT_AFTER_CONFIG scripts.
* General documentation improvements.
Includes:
* constants refactoring
* reworked db table init
* support for $CFG->debug = -1
* functional DB tests
* fixed $DB->get_indexes() to not throw exceptions when table does not exist
* fix handling of user passwords in test db
* add debug info to exception messages
* removed unnecessary PHP debug errors from mathslib
* fixed @error suppression in get_string
* fixed PHPUnit error handler setup
* added timezone info to default install
