Having `int` there is no real profit in the size or speed, while unsigned
improves security and overall integration. ZPP supplied strings can
be then accepted directly and structs can be still handled with smaller
unsigned types for size reasons, which is safe. Yet some related places
are to go.

TS related VCWD routines depend on CWD. Thus, a premature CWD
deactivation renders the VCWD layer unusable. Same issue seems to
persist in versions < 7.2, just that the code path is actually unused so
the issue didn't show up. Still might make sense to backport this into
lower branches.
Hereby, interned strings are supported in thread safe PHP. The patch
implements two types of interned strings
- interning per process, strings are not freed till process end
- interning per request, strings are freed at request end
There is no runtime interning.
With Opcache, all the permanent iterned strings are copied into SHM on
startup, additional copying into SHM might happen on demand.
* PHP_OS_FAMILY is now a macro, to allow extensions to take advantage of it, it is defined in php.h
* Values are not upper-case-first, not always uppercase. Windows is no longer just "Win", if we want the short version for testing then PHP_OS is always WINNT anyway
As in previous variant, locking is removed and the initialization
is done only once at process start. The CNG API turns out to be
faster, also the initialization is less resources hungry. The
initialization part could need to be improved, if too much startup
failures are sighted in the real world usage. Though that would mean
having locking back.
The usage of CNG was already pointed out and requested in several
reports, with the further refactoring it appears to make sense and
simplify things a backward compatible way.
This reverts commit 23bd7bcde0.
Looks like this change is unstable. If same CSP is use but multiple processers,
the initialization failures are possible. Thus, CryptAcquireContext in
every process, even if it won't be used at all, is not sensible. This
might actually motivate to look for better CSP APIs.

The test scripts bug64720.phpt and bug68652.phpt were relying on the buggy behavior, when PHP returns "Undefined static property" error due to class entry corruption. With my fix for bug 74053, both tests return no errors now, I corrected the EXPECTF accordingly

vs(tr)pprintf is now implemented in Zend on top of
printf_to_smart_str(int), which is provided as a utility function.
This allows us to efficiently printf to the end of a smart string.
If PHP CLI is used with programs with no Unicode support, the default
PHP console codepage might cause backward incompatible behaviors. This
is solved with this patch by separating the handling of I/O codepage.
As per https://wiki.php.net/rfc/default_encoding input_encodnig and
output_encoding are centralized INI settings, so they're used for the
purpose of adjusting the codepage. This gives user the ability to use
UTF-8 internally, while letting the system API to convert the output
to a compatible codepage. This also might solve the font issues on
systems without good true type support.
Note, that there no change to the default behavior - if input and
output encoding are not set, which is the default case, the default
charset applies to both console input and output. The patch is just
a compilment to the backward compatibility, not more and not less.
If this does not break the Unix system somehow, I'll be amazed. This should get most of it out, apologies for any errors this may cause on non-Windows ends which I cannot test atm.
E_RECOVERABLE errors are reported as "Catchable fatal error". This is
misleading, because they actually can't be caught via try-catch statements.
Therefore we change the wording to "Recoverable fatal error" as suggested by
Nikita.
This is one of the last old and odd deprecated settings we still have in PHP, it was never fully implemented in all the database extensions and should probably have been gone back in 5.4, along with safe_mode. Although if my memory strikes me right, mysql was also supporting it back then, but not mysqli.
So far only interbase was supporting this feature, and the removal of it causes two effects for interbase:
- CREATE DATABASE is now allowed no matter
- The default database set by php.ini (ibase.default_db) is no longer forced

This moves the WSACleanup() call to after zend_shutdown() in main.c, I did some testing and I could not find any issues with this. I don't expect this to cause any issues on Netware either, although untested as I do not have such an env available (do we even support Netware anymore? Last release was in 2009 and it is now discontinued)
Besides the movie, then this commit also contains a fix to the check of WSAStartup() where we don't actually confirm we get the desired version of the winsock.dll (We use 2.0).
To give userland developers who work with large numbers of file descriptors
the opportunity to avoid problems on systems which may not support that
many descriptors (e.g. when calling socket_select()), we make FD_SETSIZE
available in PHP as PHP_FD_SETSIZE.
Since long the default PHP charset is UTF-8, however the Windows part is
out of step with this important point. The current implementation in PHP
doesn't technically permit to handle UTF-8 filepath and several other
things. Till now, only the ANSI compatible APIs are being used. Here is more
about it

The patch fixes not only issues with multibyte filenames under
incompatible codepages, but indirectly also issues with some other multibyte
encodings like BIG5, Shift-JIS, etc. by providing a clean way to access
filenames in UTF-8. Below is a small list of issues from the bug tracker,
that are getting fixed:

Yet more related tickets can for sure be found - on bugs.php.net, Stackoverflow
and Github. Some of the bugs are pretty recent, some descend to early
2000th, but the user comments in there last even till today. Just for example,
bug #30195 was opened in 2004, the latest comment in there was made in 2014. It
is certain, that these bugs descend not only to pure PHP use cases, but get also
redirected from the popular PHP based projects. Given the modern systems (and
those supported by PHP) are always based on NTFS, there is no excuse to keep
these issues unresolved.
The internalization approach on Windows is in many ways different from
UNIX and Linux, while it supports and is based on Unicode. It depends on the
current system code page, APIs used and exact kind how the binary was compiled
The locale doesn't affect the way Unicode or ANSI API work. PHP in particular
is being compiled without _UNICODE defined and this is conditioned by the
way we handle strings. Here is more about it
https://msdn.microsoft.com/en-us/library/tsbaswba.aspx
However, with any system code page ANSI functions automatically convert
paths to UTF-16. Paths in some encodings incompatible with the
current system code page, won't work correctly with ANSI APIs. PHP
till now only uses the ANSI Windows APIs.
For example, on a system with the current code page 1252, the paths
in cp1252 are supported and transparently converted to UTF-16 by the
ANSI functions. Once one wants to handle a filepath encoded with cp932 on
that particular system, an ANSI or a POSIX compatible function used in
PHP will produce an erroneous result. When trying to convert that cp932 path
to UTF-8 and passing to the ANSI functions, an ANSI function would
likely interpret the UTF-8 string as some string in the current code page and
create a filepath that represents every single byte of the UTF-8 string.
These behaviors are not only broken but also disregard the documented
INI settings.
This patch solves the issies with the multibyte paths on Windows by
intelligently enforcing the usage of the Unicode aware APIs. For
functions expect Unicode (fe CreateFileW, FindFirstFileW, etc.), arguments
will be converted to UTF-16 wide chars. For functions returning Unicode
aware data (fe GetCurrentDirectoryW, etc.), resulting wide string is
converted back to char's depending on the current PHP charset settings,
either to the current ANSI codepage (this is the behavior prior to this patch)
or to UTF-8 (the default behavior).
In a particular case, users might have to explicitly set
internal_encoding or default_charset, if filenames in ANSI codepage are
necessary. Current tests show no regressions and witness that this will be an
exotic case, the current default UTF-8 encoding is compatible with any
supported system. The dependency libraries are long switching to Unicode APIs,
so some tests were also added for extensions not directly related to streams.
At large, the patch brings over 150 related tests into the core. Those target
and was run on various environments with European, Asian, etc. codepages.
General PHP frameworks was tested and showed no regressions.
The impact on the current C code base is low, the most places affected
are the Windows only places in the three files tsrm_win32.c, zend_virtual_cwd.c
and plain_wrapper.c. The actual implementation of the most of the wide
char supporting functionality is in win32/ioutil.* and win32/codepage.*,
several low level functionsare extended in place to avoid reimplementation for
now. No performance impact was sighted. As previously mentioned, the ANSI APIs
used prior the patch perform Unicode conversions internally. Using the
Unicode APIs directly while doing custom conversions just retains the status
quo. The ways to optimize it are open (fe. by implementing caching for the
strings converted to wide variants).
The long path implementation is user transparent. If a path exceeds the
length of _MAX_PATH, it'll be automatically prefixed with \\?\. The MAXPATHLEN
is set to 2048 bytes.
Appreciation to Pierre Joye, Matt Ficken, @algo13 and others for tips, ideas
and testing.
Thanks.
