This is a funny one. I discovered that lstat_stat_variation10.phpt was failing every
now and again when the PHP test suite was run on my dev PC. The output from the failing
test showed that the atime (access time) of the directory created in the test was changing
between these lines:
$old_stat = stat($dirname);
clearstatcache();
sleep(1);
var_dump( is_dir($dirname) );
$new_stat = stat($dirname);
Could is_dir() be accessing the directory and changing the atime? strace showed that is_dir
was only issuing a single stat() syscall. Could stat() change the atime? No, no, that would
just be perverse. Nobody would be stupid enough to implement the kernel in that way.
Checked the kernel source, found that the function called when atime needs to be updated
appears to be touch_atime(). Broke out the BCC kernel tracing tools and ran this one
while running the flaky test case in a loop:
sudo trace -I<kernel src dir>/include/linux/path.h -I<same>/include/linux/dcache.h 'touch_atime(struct path *path) "%s", path->dentry->d_name.name'
Inspecting the results showed that something called "git_thread" was occcasionally updating
the atime on the directory in question!! What on earth...???
The PID shown by trace revealed that this was a background thread for Sublime Text 3.
Sublime now has git integration and shows when there are untracked or modified files. It
seems that it uses a background thread to regularly scan the project directory and look
for new and modified files. This was causing the atime to change.
Even though other developers may not be running ST3, there are any number of reasons why
a background process might recurse through various directories and could cause the atime
to change unexpectedly. Therefore, update the test case so it doesn't fail in such cases.
Closes GH-5553.
Partially reverts 846b647953: instead of
throwing, this skips uninitialized typed properties when serializing objects.
This makes serialize with __sleep() behave the same as serialize()
without __sleep().
As in the non-__sleep() case, unserialize(serialize($x)) identity
may not be preserved due to replacement of uninitialized/unset
properties with default values. Fixing this will require changes to
the serialization format.
Closes GH-5396.
When ArrayObject is round-tripped through serialize() and unserialize(),
it forgets any iterator class name which was set using ::setIteratorClass().
Fix that.
It seems like on many filesystems nlink for directories is the
number of subdirectories (plus two, due to . and ..). However,
this is not a POSIX requirement, and some filesystems don't
implement it this way. This seems to be the case for whatever is
used on the Travis AArch64 builders now.
The primary motivation to have each test worker running its own console
is to allow the windows_mb_path tests to run in parallel. A nice side
effect is that this also prevents changing the code page of the
tester's console window (which can even cause its font to be changed).
To be able to do so, we introduce the `create_new_console` option for
`proc_open()`, which might occasionally be useful for other purposes
than testing.
To be able to see changes done only with `SetEnvironmentVariable()`, we
have to use `GetEnvironmentStrings()` instead of `environ`, because the
latter sees only changes done with `putenv()`.
For best backward compatibility we're using `GetEnvironmentStringsA()`;
switching to the wide string version likely makes sense for master,
though.
The fix for bug #78929 disabled the conversion of spaces in cookie
values to plus signs, but failed to adapt `php_setcookie()`
accordingly, so that it uses raw URL encoding as well.
Previously this generated a notice, but would likely generate an
Error when unserializing.
Now we treat it with the same distinction as direct property
accesses, i.e. referencing an unset/undefined normal property
stays a notice, while a typed property becomes an Error exception.
This fixed bug #79002.
Closes GH-5050.
This test fails intermittently due to taskill reporting failure to kill
the process (because it already has been terminated). We increase the
sleep time, to hopefully prevent that from happening again.
Instead of populating a hashtable of property names and then
directly serializing.
This has the advantage of a) detecting duplicate properties more
precisely and b) gives us the ability to discard values without
rewriting the serialization string after the fact for GH-5027.
