On this benchmark:
function simple_string_escape() {
$a = "test'asd'asd'' asd\'\"asdfasdf";
for($i=0; $i<512; $i++) {
$a .= chr($i%256);
}
for ($i = 0; $i < 100000; $i++) {
if ($a === stripslashes(addslashes($a)))
$a .= chr($i%256);
else {
echo "error at i=".$i."\n";
return;
}
}
}
the execution time goes from 21.619s to 8.139s (165% speedup) on an A1 Graviton instance.
When removing the characters that need escaping, i.e., this benchmark:
function simple_string() {
$a = "testasdasd asdasdfasdf";
for ($i = 0; $i < 10000; $i++) {
if ($a === stripslashes(addslashes($a)))
$a .= "test dedeasdf";
else {
echo "error at i=".$i."\n";
return;
}
}
}
the execution time goes from 2.932s down to 0.516s (468% speedup) on an A1 Graviton instance.
This test does not work on Windows, if the child process has OPcache
enabled via php.ini, since TEMP is not set in the environment, so
OPcache can't find the base address file, and terminates the childs.
To avoid this (and potentially some other issues regarding missing
environment variables, such as PATH), we force the child process to
ignore any ini files.
This adds support for doing something like:
[1 => ['pipe', 'w'], 2 => ['redirect', 1]]
This will make descriptor 2 on the child end a dup'd descriptor 1.
This is mainly useful in conjunction with shell-less mode, because
we don't have an easy way to do "2>&1" there.
Additionally we support:
[1 => ['pipe', 'w'], 2 => ['null']]
Which would be the same as a >/dev/null or >nul redirect, depending
on platform.
The test currently assumes that we'll first read the data of
stdout and stderr and then see eof on stdout and stderr. However
we could also read stdout, see eof on stdout, read stderr and see
eof on stderr, depending on timing.
Avoid output ordering issues by collecting events into a per-pipe
array, so interleaving is not visible.
The time goes from 0.838s down to 0.029s (a 28x speedup) on a Graviton A1
instance and the following benchmark:
function simple_crc32() {
$a = "foo";
for ($i = 0; $i < 10000; $i++) {
crc32($a);
$a .= "o".$i;
}
}
No notice is thrown for list() accesses, because we did not come
to an agreement regarding patterns like
while ([$key, $value] = yield $it->next()) { ... }
where silent null access may be desirable.
No effort is made to suppress multiple notices in access chains
likes $x[0][0][0], because the technical complexity this causes
does not seem worthwhile.

This test hangs on Windows for ~10 minutes as of commit 30019f4, so we
temporarily skip it. The issue will be investigated by Joe and myself
in due course.
`time_t` defaults to `_time64` (which is 64bit signed) even on x86, but
`Int32x32To64()` truncates it to signed 32bit. We replace the macro
with the "manual" calculation.
This has been sporadically failing on macos for a while. We've tried
a couple of things (using int arithmetic, normalizing to gettimeofday),
but this issue remains. I'm adding some tolerance to the test to
avoid CI failures.
Removed unused checks:
- mbsinit check removed, HAVE_MBSINIT removed (not used in php-src)
- mempcpy check removed, HAVE_MEMPCPY removed (not used in php-src anymore since
560ed89bfb which uses PHP's own implementation)
- strpncpy check removed, added via a8c9e893b6 and
not used.
- setpgid check removed since HAVE_SETPGID is not used
Moved to a central configure.ac:
- fpclass
- mbrlen moved to configure.ac (since the HAVE_MBRLEN is used accross the php-src)
- sigprocmask
- getcwd
- getwd
- glob
- strfmon
- nice
Duplicated checks removed:
- gethostname
- getlogin
- getpwuid_r
- socketpair
- mprotect check simplified
Also adds an --asan flag to run-tests.php to setup all the necessary
environment variables. Some tests are marked as skipped because they
are incompatible with asan or too slow.
I'm basing this on the DEBUG_ZTS build, which seems to give us the
most mileage.
In this case the progarm will be executed directly, without a shell.
On Linux the arguments are passed directly to execvp and no escaping
is necessary. On Windows we construct a command string using escaping
with the default Windows command-line argument parsing method described
at https://docs.microsoft.com/en-us/cpp/cpp/parsing-cpp-command-line-arguments.
Apart from avoiding the issue of argument escaping, passing an array
and bypassing shell has the advantage of allowing proper signal
delivery to the opened process (rather than the shell).
The strcoll function is defined in the C89 standard and should be
on today's systems always available via the <string.h> header.
https://port70.net/~nsz/c/c89/c89-draft.html#4.11.4.3
- Remove also SKIPIF strcoll check in test
Some headers were checked multiple times in the main configure.ac file
and in the bundled extensions or SAPIs themselves. Also many of these
checks are then used accross other extensions or SAPIs so a central
configure.ac makes most sense for these checks.
Fails for me locally due to different number of warnings with
different messages. Rather than adding more wildcards I'm dropping
this test entirely, as it doesn't seem to test anything particularly
useful.
(cherry picked from commit 84333cad67)
The use of gettimeofday in time_sleep_until is technically incorrect, it's not possible
to use gettimeofday in this way reliably on any platform: It relies on operating system
global structures, which may be modified by any other process on the system at any time.
While in practice, users may be ignoring this flaw, it entirely depends on the other software
running on the system to which the application is deployed, there is no possible way to write
a test that will always pass on any system, therefore it must be marked XFAIL.
I've refactored based on the original bug report, related bugs, and commits
to php-src that were related to them.
It is supposed to be testing windows specific behaviour related to non-blocking pipes,
nevertheless the test runs everywhere.
As this test doesn't check differences in times before and after
operations, it doesn't actually verify anything and just wastes
30 seconds of test time.
As we already have other tests that do check how stat times change,
I'm removing it entirely.
This reverts commit bdcef51bcb.
It seems that pkg-config support for libargon2 is still flaky:
* No pc file on Alpine.
* Custom builds of released libargon2 versions create a broken
pc file. This is fixed in master, but not released.
Go back to the old detection code for now.
On some recent Windows systems, ext\pcre\tests\locales.phpt fails,
because 'pt_PT' is accepted by `setlocale()`, but not properly
supported by the ctype functions, which are used internally by PCRE2 to
build the localized character tables.
Since there appears to be no way to properly check whether a given
locale is fully supported, but we want to minimize BC impact, we filter
out typical Unix locale names, except for a few cases which have
already been properly supported on Windows. This way code like
setlocale(LC_ALL, 'de_DE.UTF-8', 'de_DE', 'German_Germany.1252');
should work like on older Windows systems.
It should be noted that the locale names causing trouble are not (yet)
documented as valid names anyway, see
<https://docs.microsoft.com/en-us/cpp/c-runtime-library/locale-names-languages-and-country-region-strings?view=vs-2019>.

And convert some object to string conversion related recoverable
fatal errors into Error exceptions.
Improve exception safety of internal code performing string
conversions.
Fails for me locally due to different number of warnings with

This allows writing
array_merge(...$arrays)
instead of
array_merge([], ...$arrays)
and is in line with similar changes to array_push() and array_unshift()
in PHP 7.3.
Closes GH-4175.
There really isn't any practical difference between these two, but repo
currently uses *.tiff files more than 8.3 variant filenames of *.tif.
Also these aren't part of the test.
Normalization include:
- Use dnl for everything that can be ommitted when configure is built in
favor of the shell comment character # which is visible in the output.
- Line length normalized to 80 columns
- Dots for most of the one line sentences
- Macro definitions include similar pattern header comments now
The execution time goes from 4.388s down to 0.563s on a Graviton A1
instance for the benchmark:
function reverse_strings() {
$a = "foo";
for ($i = 0; $i < 100000; $i++) {
strrev($a);
$a .= "o";
}
}
HT_FLAGS() includes the full flag word, including the iterator
count. When we're fully reassigning it, we need to make sure that
we either really do want to copy the iterator count (as in some
cases in array.c) or we need to mask only the actual flag byte.
Add an assert to hash_iterators_del() to make sure the iterator
count is non-zero (which is how I ran into this) and make sure that
the iterator count is correctly preserved during array splicing.
This one looks semi-legit, in case php_stream_eof() returns false
but php_stream_get_line() fails. Not totally sure this cannot
happen, so rewriting to check both conditions at once.
And fix incorrect variable shadowing in add_config_entry(). However,
the test doesn't hit this case, as it requires a nested array. I'm
not sure if it's possible to produce nested arrays from ini?
Checking for the strerror function presence is no longer needed since it
is part of the C89 standard [1] and can be safely assumed that all
current systems have it.
Check in the configure.ac and Windows defined symbol are still left
until the file library (libmagic) will be updated.
