For some reason, `ImageLoad()` fails to load images with a relative
path starting with `.\` or `./`. We work around this issue by
stripping those leading characters.
We have to actually determine the proper `SIZEOF_OFF_T`.
Interestingly, it is `4` on Windows x64.
We also have to prevent the redefinition in pg_config.h. The clean
solution would likely be to not include pg_config.h at all, but that's
out of scope for BC reasons for now.
In the buildconf and configure batch files, Windows' cscript utility was being
run without the /e:jscript flag. This works on systems that have not had the
default .js file association changed, but if .js has been re-associated to
(say) an IDE, the batch files fail with the error message:
Input Error: There is no script engine for file extension ".js".
ASan instrumentation does not support the MSVC debug runtime, but still
it does not make sense to enable optimizations for such builds, since
they are not meant for production usage anyway, and although memory
corruption issues are still found in optimized builds, the generated
diagnostics are close to being useless, and apparently sometimes even
outright wrong. Therefore, we disable all optimizations for ASan
instrumented builds.
We also introduce and use `ZEND_WIN32_NEVER_INLINE` for ASan enabled
builds to avoid inlining of functions, so we get even better
diagnostics.
We no longer try to retrieve the filename of a given stream when
fstat'ing, because this is very slow. Since we neither didn't do that
in PHP 7.3 and earlier, we regard this as sensible trade-off.
* PHP-7.3:
Fixed bug #78910Fix#78878: Buffer underflow in bc_shift_addsub
Fix test
Fix#78862: link() silently truncates after a null byte on Windows
Fix#78863: DirectoryIterator class silently truncates after a null byte
Fix#78943: mail() may release string with refcount==1 twice
Since we need `headers_lc` as well as `headers_trim` in the following,
we do not release the former even if they are the same string, to avoid
complicating the release logic even more.
A new test case is not necessary, since we already have
mail_basic_alt2-win32.phpt and others.
If we're constructing extended-length paths (i.e. paths prefixed with
`\\?\`), we have to replace all forward slashes with backward slashes,
because the former are not supported by Windows for extended-length
paths.
The more efficient and likely cleaner alternative solution would be to
cater to this in `php_win32_ioutil_normalize_path_w()` by always
replacing forward slashes, but that might break existing code. It
might be sensible to change that for `master`, though.
We must not assume that any file which is not a directory is a regular
file. Therefore we employ `GetFileType()` in this case to properly
distinguish between character special, FIFO special and regular files.
Checking for the exact linker version appears to be too restrictive; it
should be fine if the tens match.
We also refactor to avoid repeating ourselves.
These two files have been: "UTF-8 Unicode (with BOM) text".
By applying `dos2unix` on these files the BOM has been removed.
I checked the whole source code with dos2unix:
These were the only two text files affected.
ext/win32std is unmaintained for years, so it is highly unlikely that
it is available. We therefore use regedit instead to register the
event source. We also remove the bundled syslog.reg, since it is of no
use, unless generated for the respective installation.
This reverts commit cc44bad1f6, since its
assumptions were not correct. Actually, the classic event logging is
still used by PHP, because Windows 7 is still to be supported for a
while. Without the respective registry entries, the event log entries
show an error message regarding missing ID descriptions.
Thanks to ab@php.net for hinting at this!
Obviously, the part depending on ext/win32std has still to be
overhauled, and further improvements are conceivable; we will address
this in due course.
- yp_get_default_domain was part of ext/yp
- functions checks produce HAVE_function_name symbols. These checks are
currently not used in php-src neither in the extensions out there.
- Removed symbols because they are not used in the code:
- HAVE_GCVT
- HAVE_PUTENV
- HAVE_PUTENV
- HAVE_SETVBUF
- HAVE_TEMPNAM
- HAVE_SIN (sin is also defined in C89 standard)
- HAVE_SETSOCKOPT
- HAVE_LOCKF
- HAVE_ISASCII
- HAVE_YP_GET_DEFAULT_DOMAIN (and other yp extension related unused checks)
- HAVE_LINK
- HAVE_USLEEP is already defined in Windows configuration header
- HAVE_LIBBIND has not been used in php-src for a while anymore
- HAVE_GETHOSTNAME is duplicated in Windows configuration header
Closes GH-4417
These are part of the C89 and on today's systems not needed to be
checked anymore. This removes symbols HAVE_SIGNAL and HAVE_STRERROR.
- http://port70.net/~nsz/c/c89/c89-draft.html
- locale.h is also part of C89 but will be removed per request in PHP 8
While it is already possible to *set* CFLAGS and LDFLAGS (actually all
variables) from the environment for `nmake` (by passing the `/E`
option), it is not possible to *add* any (C|LD)FLAGS, which can be
useful in some cases. Instead of allowing this for `nmake`, we add
support for additional custom (C|LD)FLAGS to `configure`, similar to
how that works on Linux, so one could actually write:
````
set CFLAGS=foo & set LDFLAGS=bar & configure
````
This also allows us to use these flags during configure.
The following functions don't need to be checked anymore since the
they are not used across the code or the symbols aren't used anymore:
- cuserid (not used)
- lrand48 (not used and removed via
6d6ef7aacc)
- random (check is not used)
- srand48 (not used)
- srandom (not used)
- strdup (check is not used)
and the unused check symbols:
- HAVE_CUSERID
- HAVE_LRAND48
- HAVE_RANDOM
- HAVE_SRAND48
- HAVE_SRANDOM
- HAVE_STRDUP
Closes GH-4338
The limits.h header is part of the C89 and is today available
everywhere. There is no need to check for presence of this header
anymore.
The timelib has already been patched upstream via
aae5907cb7
PHP extensions out there shouldn't rely on symbols defined during the
build anyway and neither they do on this particular symbol anymore.
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
Instead of checking GetBinaryType() for each file, we do a much cheaper
pre-check whether the filename extension matches .exe or .com, and call
GetBinaryType() only in this case. For BC we also report .bat and .cmd
files as executables again.
The patch has been provided by @weltling.
RFC: https://wiki.php.net/rfc/tostring_exceptions
And convert some object to string conversion related recoverable
fatal errors into Error exceptions.
Improve exception safety of internal code performing string
conversions.
php_win32_signal_system_ctrl_handler() is called from a kernel thread,
so the former initialization of `vm_interrupt_flag` has no effect,
since it is defined as thread-local. This is, however, not necessary,
since the CTRL signal handling is supposed to work only for the main
thread anyway. We therefore change `vm_interrupt_flag` and the related
variables to true globals.
This also allows us to unmark the respective test case as XFAIL.
Furthermore, `vm_interrupt_flag` is declared as `zend_bool *`, so we
better treat it such.
Since PHP strings are binary safe (i.e. they may contain NUL bytes), we
must not assume that strlen()/wcslen() actually return the length of
the string. Only if the given in_len is zero, it is safe to assert
this.
