In d62f535caa, the legacy mbstring conversion filters for Shift-JIS
was updated to restore backwards-compatible mappings for 0x5C/0x7E.
Make the same change to the newer fast conversion filters.
According to the relevant Japan Industrial Standards Committee standards,
SJIS 0x5C is a Yen sign, and 0x7E is an overline.
However, this conflicts with the implementation of SJIS in various legacy
software (notably Microsoft products), where SJIS 0x5C and 0x7E are taken
as equivalent to the same ASCII bytes.
Prior to PHP 8.1, mbstring's implementation of SJIS handled these bytes
compatibly with Microsoft products. This was changed in PHP 8.1.0, in an
attempt to comply with the JISC specifications. However, after discussion
with various concerned Japanese developers, it seems that the historical
behavior was more useful in the majority of applications which process
SJIS-encoded text.
Since we are now treating SJIS 0x5C as equivalent to U+005C and 0x7E as
equivalent to U+007E, it does not make sense to convert U+203E (OVERLINE)
to 0x7E, nor does it make sense to convert U+00A5 (YEN SIGN) to 0x5C. Restore
the mappings for those codepoints from before PHP 8.1.0.
Fixes GH-8281.
There is not much point in having two distinct file mappings; since the
info mapping is very small and of fixed size, we can put it at the
beginning of a single mapping. Besides the obvious resource savings,
that also simplifies the error handling.
Closes GH-8648.
We also fix gh8626.phpt for the firebird driver by allowing negative
status codes as well. We mark the other two test cases as xfail for
the firebird driver for now.
Closes GH-8666.
It introduces a single function to check file paths passed to OpenSSL
functions. It expands the path, check null bytes and finally does
an open basedir check.
This has been introduced as part of fixing https://bugs.php.net/79532 (67f9b0b754) because ``pg_config.h`` was included.
As this is no longer the case we don't need this undef any more.
* Fix regression from GH-8587
Streams hold a reference to the stream wrapper. User stream wrappers
must not be released until the streams themselves are closed.
* Add test for directories
This test was written to always use the sqlite PDO driver; however,
that driver may no longer be available[1], and actually the test is
supposed to work for all drivers – otherwise it should be placed in
ext/pdo_sqlite/tests.

Closes GH-8732.
Casting a huge unsigned value to signed is implementation-defined
behavior in C. By introducing the ZEND_THREEWAY_COMPARE() macro, we
can sidestep this integer overflow/underflow/casting problem.
