The 2nd release candidate for PHP 5.2.1 is now available for
download. The tarballs can be found here:

http://downloads.php.net/ilia/php-5.2.1RC3.tar.bz2

(c5b3e5540d1951d4c4b976b8a39c09ab)

and the Win32 binaries will be available in short order.

Since the last release, there are over 20 different bug fixes
resolving some annoying engine issues such as the tempval leak inside
foreach(). We do not anticipate any regressions to be introduced by
this RC, but I would still like to ask everyone to take a few minutes
and test it against their code base. If you come across any issues
please report them at http://bugs.php.net/.

Depending on the stability of this release it may either be followed
by a final release or another RC, therefor your feedback is critical
to determining whether or not the code is stable enough to warrant
the 5.2.1 final.

Hi, a couple of things (and maybe I need some help, and everything is
assuming windows):

Has something changed with realpath() (at least on windows, my only
test)??? In 5.2.0 if the file does not exist, it returns false, but in
5.2.1RC2 and 5.2.1RC3 it returns the path to a non-existing file.
(Used fastcgi/nts version to test)
I love having the nts versions. That way I can use FastCGI on my
dev machine and have it setup like the servers. And a bit faster.
However, RC3 run times are sooo much longer than RC2 that the FastCGI
server often ends up canceling and gives the browser a Internal
Service Error 500...
When using RC3 as a handler (thread safe version), phpinfo reports
PHP 5.2.0 but under apache2handler is says 5.2.1RC3....??? And it no
longer has the real_path bug above. I no longer have any 5.2.0 files
around, and even tried restarting the machine to no effect. I always
install manually, never using the msi installer.

Hope this report helps in any way.

Thanks!

Hi steve,

When using RC3 as a handler (thread safe version), phpinfo reports
PHP 5.2.0 but under apache2handler is says 5.2.1RC3....??? And it no
longer has the real_path bug above. I no longer have any 5.2.0 files
around, and even tried restarting the machine to no effect. I always
install manually, never using the msi installer.

This looks like you're having some old php5ts.dll around which is being
loaded by the sapi instead of the new one. Please check again for that
file.

Since I have the thread safe version of rc3 running now, and it is not
there, i suspect that it might be a build issue. Do the two use or
link to different core libraries?

Bugfix for #39993 introduced LC_CTYPE variable corruption.

Is it that difficult to replace strcasecmp with locale independent case

Bugfix for #39993 introduced LC_CTYPE variable corruption.

Please provide more details on this.

Comments in bug report stated that patch is not correct, yet patch was

From http://bugs.php.net/bug.php?id=39993

Test script:

<?php
// Set all locale vars
var_dump(setlocale(LC_ALL,'tr_TR.UTF-8'));
// get default timezone
var_dump(date_default_timezone_get());
// get current `LC_CTYPE` value
var_dump(setlocale(LC_CTYPE,0));

Expected result:

string(11) "tr_TR.UTF-8"
string(15) "Europe/Helsinki"
string(11) "tr_TR.UTF-8"

Result after Iliaa's patch:

string(11) "tr_TR.UTF-8"
string(15) "Europe/Helsinki"
string(1) "C"

Patch was applied in ext/date/lib/parse_tz.c revision 1.20.2.6.2.10.
http://cvs.php.net/viewvc.cgi/php-src/ext/date/lib/parse_tz.c?view=log

OS - Linux Debian Etch. glibc 2.3.6.

Tested PHP versions:

php 5.2.0-8 debian - timezone database corruption error
php5.2-200701011130 - timezone database corruption error
php5.2-200701241930 - LC_CTYPE environment variable is modified after
date_default_timezone_set/get calls.

If you set LC_CTYPE to C, you might break gettext translations that don't
set codeset with bind_textdomain_codeset().

Is it that difficult to replace strcasecmp with locale independent case
insensitive comparison function?

We're open for patches. Feel free to send one.

I am PHP developer and don't code in C. In PHP script locale insensitive
strtolower/strtoupper can be done with one preg_replace call.

All timezone identifiers are written in plain US-ASCII. Lowercase ASCII
characters are in 0x61-0x7A range, uppercase characters are in 0x41-0x5A.
Maybe you can add 0x20 to all 0x41-0x5A byte values and use strcmp()
instead of strcasecmp().

PHP needs locale insensitive strcasecmp() or your developers will continue
hitting string comparison issues in Turkish and Azerbaijani. Ilia patched
it in timezone parsing code. Some day other strcasecmp will pop in other
place.

Switching locale everytime you want to compare strings is a hack and not a
bug fix.

I did not and I do not like it either, but it fixes the problem and does not introduce any new issues (anymore).
If you think it's wrong and you have a better patch - send it to the list and we'll discuss it together.

I actually agree there and it was one of the reasons why I didn't like
this patch. However, it is the quickest way to do this for now.

Its a solution that works. There are very few instances where such

posix locales will not be used.

This is not true at all.. I even think this is a big misconception of PHP 6.
Although this has nothing to do with the issue mentioned above, we will
still need setlocale() in PHP 6 because of externals libs. Even the bundled
PCRE uses locales, and that is very handful (e.g. locale-dependent '\w').
So, POSIX locales will be deprecated for string handling, date formatting
and such things, but they will still be used by external libs.

Nuno,

The idea is that while internal libs will use it, PHP will do all the
user-locale handling internally.

PCRE should operate in UTF-8 mode.

So are you saying that php will automatically issue setlocale() calls?
e.g.:
<?php
i18n_loc_set_default('pt_PT'); // or whatever that is called these
days
//now it magically calls setlocale('pt_PT', 'pt_PT.iso8859-1',
'portuguese'); -- linux/bsd/windows

echo preg_match('/^\w+$/', "àáãçêõ"); //prints 1?
?>

Because with UTF-8, PCRE already knows the uppercase and lowercase
equivalents, without having to rely on the POSIX locales.

But how do I match only portuguese letters? you'll (always) need posix
locales..
I don't think forcing preg_* function to utf-8 is a good idea, but anyway I
haven't looked enough to PHP 6 (yet) to produce a strong opinion.

I've been thinking about how to not force UTF-8 in PCRE for PHP 6, and
it's not that simple. This is mainly due to preg_replace(), because it
allows array() parameters that can contain mixed IS_UNICODE and
IS_STRING values. I hope you realize though, that in UTF-8 mode PCRE
does not care about POSIX locales, even in PHP 5.

By the way, I think ICU regexp extension, when implemented, will let
you match Portuguese characters in UTF-8 strings.

locales..
I don't think forcing preg_* function to utf-8 is a good idea, but
anyway I haven't looked enough to PHP 6 (yet) to produce a strong
opinion.

Because with UTF-8, PCRE already knows the uppercase and lowercase
equivalents, without having to rely on the POSIX locales.

PCRE should operate in UTF-8 mode.

How does UTF-8 help to make it locale compliant?

I've been thinking about how to not force UTF-8 in PCRE for PHP 6, and
it's not that simple. This is mainly due to preg_replace(), because it
allows array() parameters that can contain mixed IS_UNICODE and IS_STRING
values. I hope you realize though, that in UTF-8 mode PCRE does not care
about POSIX locales, even in PHP 5.

I haven't though on that, but can't you simply reject mixing of unicode and
binary strings?

By the way, I think ICU regexp extension, when implemented, will let you
match Portuguese characters in UTF-8 strings.

I wasn't aware of that API.. anyway it is probably slower than pcre+locales
(because it uses unicode propertie table lookups)

Yes, UTF-8 covers many aspects but does it know about words, white
spaces (not sure if ws are always the same) and other locale specific
issues? generally, not only pcre. Maybe it is more something for ICU
directly, as you said later in this thread.

That's not really a problem with pcre, as it supports unicode character
properties. It isn't documented in phpdoc (don't look at me :P), but it
looks like:
\pL
where L is one of (from http://pcre.org/pcre.txt):
L Letter
Ll Lower case letter
N Number
Nd Decimal number
Nl Letter number
No Other number
P Punctuation
Zs Space separator
(...)

Please do not confuse an encoding (UTF-8) with full locale information
(which is what CLDR provides).
