FreeBSD calls it tidy5. Still, the check is not perfect, as both
old and new lib can coexist. ATM, the preference is to pick up the
old lib, still. In it's absense the new one will be looked up.
Our existing test 024.phpt actually tests incorrect behavior. There is
a self-closing tag present in the input, but the expected output has
that same tag half-open (i.e. open but never closed). To support
tidy-html5, which does the right thing, that test needed to be
changed. The self-closing tag was replaced by an explicit pair of
tags, and some extra whitespace fudging was done.
One of the tests for tidy (016.phpt) is testing that we can use a
configuration file (016.tcfg) instead of a string to configure
tidy. It was observing the output of an API call, which proved too
fragile now that we support tidy-html5 as well. Instead, the test was
updated to inspect $tidy->getConfig() to ensure that the config file
was actually processed and will be respected.
One of the tidy tests expects some output that has (harmlessly)
changed in tidy-html5. The "EXPECT" block for that test was changed to
"EXPECTF" and mangled to accept both the old and new outputs.
Some of the tidy tests expect output that can change. The motivating
example is an object "id" that is some integer, but no integer in
particular. Those hard-coded values have been changed to accept any
integer so that the test suite passes when tidy-html5 is used.
The test suite for the tidy extension was written before HTML5 was
"standardized". The new tidy-html5 library will output an HTML5
DOCTYPE in the absence of any other information, so the expected test
outputs have been updated to accomodate the absense of an HTML version
(which is how you declare "HTML5").
Our existing libtidy support is based on the legacy "HTML tidy"
project. That project now has a successor called tidy-html5, where all
new features and bugfixes happen. Of particular note are the fixes for
two security vulnerabilities, CVE-2015-5522 and CVE-2015-5523.
The API is largely unchanged in the new project (which is truly the
successor of the original -- not a fork), and so it is almost a
drop-in replacement as far as PHP is concerned. However, one file has
changed in the new project: "buffio.h" has been moved to
"tidybuffio.h".
This commit detects the presence of tidybuffio.h at build time, and
then adjusts the import statement in tidy.c accordingly. The result is
a build that works against either the legacy project or the new
tidy-html5 project, although the test suite for the tidy extension now
fails. Those failures are not critical and will be fixed.

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:
https://bugs.php.net/63401https://bugs.php.net/41199https://bugs.php.net/50203https://bugs.php.net/71509https://bugs.php.net/64699https://bugs.php.net/64506https://bugs.php.net/30195https://bugs.php.net/65358https://bugs.php.net/61315https://bugs.php.net/70943https://bugs.php.net/70903https://bugs.php.net/63593https://bugs.php.net/54977https://bugs.php.net/54028https://bugs.php.net/43148https://bugs.php.net/30730https://bugs.php.net/33350https://bugs.php.net/35300https://bugs.php.net/46990https://bugs.php.net/61309https://bugs.php.net/69333https://bugs.php.net/45517https://bugs.php.net/70551https://bugs.php.net/50197https://bugs.php.net/72200https://bugs.php.net/37672
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.

Use the new 'ZSTR' macros in the rest of the code.
Does not change anything to the generated code (thanks to compat macros) but cleaner.

Improve zend_string API
Add missing methods
This implements a reduced variant of #1226 with just the following
change:
-Fatal error: Uncaught exception 'EngineException' with message 'Call to private method foo::bar() from context ''' in %s:%d
+Fatal error: Uncaught EngineException: Call to private method foo::bar() from context '' in %s:%d
The '' wrapper around messages is very weird if the exception
message itself contains ''. Futhermore having the message wrapped
in '' doesn't work for the "and defined" suffix of
TypeExceptions.
TypeException stays as-is for now because it uses messages that are
incompatible with the way exception messages are displayed.
closure_038.phpt and a few others now show that we're generating
too many exceptions for compound operations on undefined properties
-- this needs to be fixed in a followup.
