On NixOS, the output of phpinfo() can get very large, causing us to run into the
backtracking limit. Lazy matching for .*/.+ can help reduce backtracking.
We need to avoid signed integer overflows which are undefined behavior.
We catch that, and set `offset` to `ZEND_LONG_MAX` (which is also the
largest value of `zend_off_t` on all platforms). Of course, that seek
may fail, but even if it succeeds, the stream is no longer readable,
but that matches the current behavior for offsets near `ZEND_LONG_MAX`.
Closes GH-15989.

This was first reported as a leak in GH-15026, but was mistakingly
believed to be a false positive. Then an assertion was added and it got
triggered in GH-15908. This fixes the leak. Upon merging into master the
assertion should be removed as well.
Closes GH-15924.
column_long and index_long might not be set, but are still used as arguments.
They are not actually used if column_str is set, but it's better to initialize
them anyway, if only to make MemorySanitizer happy.
We were using atoi, which is only for integers. When the size does not
fit in an integer this breaks. Use ZEND_STRTOUL instead. Also make sure
invalid data isn't accidentally parsed into a file size.
Closes GH-15035.
It turns out that on a 32-bit system, this test can produce either the
"usual" expected output from the 64-bit test, OR the 32-bit-only
integer overflow message. We copy the dual expected outputs from
chunk_split_variation1_32bit.phpt to handle both cases.
This fixes an earlier commit that split the two tests based only on
the size of an int (32-bit versus 64-bit). The CI reveals that, at
least on a debug/zts build, the "64-bit" memory limit error (and not
the integer overflow error) is still produced.
The test in strings/wordwrap_memory_limit.phpt has a counterpart in
strings/wordwrap_memory_limit_win32.phpt. The two are conditional on
both the OS name and the size of an int (32- versus 64-bits).
A Gentoo Linux user has however reported that the 64-bit test fails on
a 32-bit system, with precisely the error message that the "win32"
test is expecting. I don't have any 32-bit hardware to test myself,
but I think it's reasonable to conclude that the OS name is not an
essential part of the test: it's simply 32- versus 64-bit.
This commit drops the conditionals for the OS name. Now one test will
be run on 32-bit systems, and the other on 64-bit systems, regardless
of the OS name.
Bug: https://bugs.gentoo.org/935382
In strings/chunk_split_variation1_32bit.phpt, we have a test that is
expected to fail on x32 with a possible integer overflow error. The
message reports the exact number of bytes -- a number big enough to
overflow an int on x32 -- stemming from a memory allocation in
chunk_split().
This number appears unpredictable, and is not the point of the test.
We replace it with %d to make the test independent of the allocation
details.
The old code checked for suffixes but didn't take into account trailing
whitespace. Furthermore, there is peculiar behaviour with trailing dots
too. This all happens because of the special path-handling code inside
CreateProcessW.
By studying Wine's code, we can see that CreateProcessInternalW calls
get_file_name [1] in our case because we haven't provided an application
name. That code gets the first whitespace-delimited string into app_name
excluding the quotes. It's then passed to create_process_params [2]
where there is the path handling code that transforms the command line
argument to an image path [3]. Inside Wine, the extension check if
performed after these transformations [4]. By doing the same thing in
PHP we match the behaviour and can properly match the extension even in
the given edge cases.
