This variant of crc32 is heavily used by storage systems, such as iSCSI, SCTP,
Btrfs, ext4, and is increasingly being used in API (such as Google Cloud
Storage, and Apache Kafka).
This check introduced in 2004 is wrong and removed. A HEAD request with
curl does *not* cause this error code - only if you make a regular GET
request but tell curl to send a HEAD using CURLOPT_CUSTOMREQUEST and
then you've asked for it.
You do a proper HEAD request with curl by setting the CURLOPT_NOBODY
option to 1L.
This was the case in 2004. This is still the case in 2019. This is also
documented in libcurl documentation.
This check hides the possibly serious error when this error code is
genuinely and correctly returned by curl because the transfer was
truncated and ended up partial.
As can be seen, I objected to this change already in the original bug:
https://bugs.php.net/bug.php?id=27341
GetFinalPathNameByHandleW is given a file handle to a symbolic link,
rather than one to the target, and therefore returns an incorrect path.
Fix symlink with relative path and add test
- remove some outdated and not used macro calls
- remove some unused variables
- Remove not needed comment from tokenizer config.m4
- Remove not needed comment
- remove not needed local variables for editors and syntax highlighting
The AC_CHECK_TYPE was refactored in more recent versions of Autoconf
and the call with two arguments is obsolete and not recommended anymore.
This patch also refactors some leftovers of using ulong and uint which
are not standard nor common usages of types in C.
The ulong can be used as zend_ulong and uint usage is actually
`unsigned int`.
The usage of HAVE_ULONG removed since it is not used in current code
base.
Legacy edgecase for some legacy HPUX systems removed:
- sys/stream.h header is not checked and the HAVE_SYS_STREAM_H is
not defined with current build system.
- flags are unsigned int
- max_allowed_packet changed to unsigned int
Signed shift of 31 for int and 63 for long is flagged as undefined
behavior by UBSan (-fsanitize=undefined) and seems to be indeed so
according to the standard.
The patch converts such cases to use unsigned.
We cannot replace an op1_def opcode with an ASSIGN, if it also has
a used res_def. Usually this doesn't happen because the res_def use
can be eliminated first. The example is a case where operand replacement
on the res_def use fails.
Changes:
- PHP_TM_GMTOFF removed
- HAVE_TM_GMTOFF replaced with HAVE_STRUCT_TM_TM_GMTOFF
- HAVE_TM_ZONE replaced with HAVE_STRUCT_TM_TM_ZONE
- HAVE_TZNAME removed
The PHP_TM_GMTOFF macro can be replaced with Autoconf's AC_CHECK_MEMBERS
that defines the HAVE_STRUCT_TM_TM_GMTOFF symbol instead of the
HAVE_TM_ZONE.
The HAVE_TZNAME symbol is not used in current code. The obsolete
HAVE_TM_ZONE symbol has been replaced with more proper
HAVE_STRUCT_TM_TM_ZONE. These are defined by the AC_STRUCT_TIMEZONE
macro.
