This format matches against null bytes, and prevents the test
expectation from being interpreted as binary data.
bless_tests.php will automatically replace \0 with %0 as well.
PR #6787 changed the behavior of the `--EXTENSIONS--` section, so that
not yet loaded extensions are dynamically loaded if possible. However,
when no tests are specified for the runner, only tests for already
loaded extensions are run, what defeats the purpose of the improvement
of the `--EXTENSIONS--` behavior. We cater to that by detecting
loadable extensions, and also run their tests.
This is a re-application of the original match against master.
The patch was originally applied to master, then reverted from
there, incorrectly applied to PHP-8.0, reverted from there due
to ABI break, and now lands on master again. We can only hope
that it does not get reverted again ;)
For rationale, see https://github.com/php/php-src/pull/6787
Make extension checks lowercase, add a special case for opcache
that has internal name not matching .so filename.
Extensions migrated in part 2:
* dom
* exif
* fileinfo
* ffi
Currently, most skip checks are just for making sure an extension is
available. Even with recent addition of skip caching, this makes tests
needlessly slow:
* Checks for the same extension in its tests can have small differences
impacting cacheability.
* Even identical skip checks in two tests can still be executed twice if
they're run by different workers.
To remedy this, I'm repurposing the existing --EXTENSIONS-- section of
.phpt files to specify wjich extensions are required for current test to
run. Current behavior:
1) If the extension is already visible to PHP, all is good
2) If it isn't, assume it's present as a shared module and attempt to add
it via a command line parameter
3) If that works, all is good
4) If it doesn't, PHP fails with a cryptic error message trying to
execute the test itself
After this commit:
1) and 2) are kept unchanged
3) Check if shared extension file from 2) is actually present
4) Skip the test if it isn't
Other benefits include clear skip reasons (vs. sometimes none in many
current skip checks) and moving test information from code to metadata,
opening more opportunities for search and analysis.
Since --EXTENSIONS-- is barely ever used, this change poses no risk of
hidden failures.
As a demonstration of the new approach, this commit migrates one
extension to it. If merged, I will migrate other extensions in
subsequent PRs.
Closes GH-6787.
This moves a bunch of code outside of run_tests(), making it a bit
more manageable. Additionally, accessors provide better readability
than isset() and friends.
This is a minimal patch that moves the code but does not refactor
much. For the sake of reviewing experience, it does not involve
further refactoring which could include:
* Removing setSection()
* Fixing up the mess with hasSection() vs. sectionNotEmpty(), only
one of which is really needed.
* Moving more repetitive code into the new class.
All of this will be done with later commits.
Closes GH-6678.
If nocache is used, then we should return an empty string result,
so the test doesn't get marked as borked.
Also limit to an occurrence at the start, just like other skip
tags.
If the SKIPIF section return nocache, don't cache the result. This
is used by tests that perform complex test set in conjunction with
skip checks, and need to be evaluated every time.
Valgrind 3.3.0 was released in 2007, not even RHEL has crap older than
this. It could be argued that 3.8.0, released in 2012, could be a safe
cutoff too.
Closes GH-6728.
The lack of such a check leads to false-passes of tests on Windows
which expect no output, but produce a segfault or similar issue. I
discovered this a while ago due to bad tests in an extension I maintain.
Closes GH-6722.
Currently every --SKIPIF-- section in every test file results in 1
extra execution of PHP, every --EXTENSIONS-- section - in 2 executions.
This is quite wasteful, as skip checking code is extremely repetitive
and extensions are fixed for every binary/ini/command parameters
combination.
This patch adds caching to all such checks.
On my machine, the gains are quite noticeable: 36s instead of 43s
with -j16, 292s instead of 337s without concurrency. Cache stats are
3780 hits, 1247 misses in the latter case. In the future, tests could
be adjusted to have more uniform skip checks to improve performance even
more.
Closes GH-6681.
When no test paths are specified this shows up when 'make test' is used on a PECL extension without specifying tests to run (or in php-src too, I guess...)
Closes GH-6717.
This deprecates passing null to non-nullable scale arguments of
internal functions, with the eventual goal of making the behavior
consistent with userland functions, where null is never accepted
for non-nullable arguments.
This change is expected to cause quite a lot of fallout. In most
cases, calling code should be adjusted to avoid passing null. In
some cases, PHP should be adjusted to make some function arguments
nullable. I have already fixed a number of functions before landing
this, but feel free to file a bug if you encounter a function that
doesn't accept null, but probably should. (The rule of thumb for
this to be applicable is that the function must have special behavior
for 0 or "", which is distinct from the natural behavior of the
parameter.)

This testing mode executes the test multiple times in the same
process (but in different requests). It is primarily intended to
catch tracing JIT bugs, but also catches state leaks across
requests.
Closes GH-6365.
