GitHub migration is not complete

Neustradamus — Sun, 30 Oct 2022 19:04:08 -0000

Can you add a "move" box like https://sourceforge.net/projects/handbrake for example.
- https://sourceforge.net/projects/pcre/

To change informations, go here: https://sourceforge.net/p/pcre/admin/overview

The new place can be added in:
- "Moved Project to", here: https://sourceforge.net/p/pcre/admin/overview
- "Preferred Support Page (for users of your project)", here: https://sourceforge.net/p/pcre/admin/overview
- A new tab, go here: https://sourceforge.net/projects/pcre/

Maybe you can add other team members in this project administration.

Thanks in advance.

#35 Error when make the project

drazde — Thu, 12 Oct 2017 07:42:42 -0000

I finnaly complite the building but I have a question:
I must move the project on a "simple" directory on MSYS2 (c:\msys2\home\ without space) because although make will fail with this error:

In file included from src/pcre2posix.c:47:0:
src/config.h:231:0: note: this is the location of the previous definition

Error when make the project

drazde — Wed, 11 Oct 2017 16:52:20 -0000

When I try to compile on MSYS (on Windos 10), I have this error

pcre_exec doesn't return PCRE_ERROR_BADUTF8 for invalid UTF8

Vincent de Phily — Thu, 05 Apr 2007 17:31:37 -0000

I found some invalid UTF8 chars that do not trigger a PCRE_ERROR_BADUTF8 error when found in the subject string :

\xF4\x92\x94\x95
\xED\xB2\x94

Tested with verion 6.6 and 7.0

See table 3-6 of http://www.unicode.org/versions/Unicode4.0.0/ch03.pdf for valid UTF8 chars.

Because of this bug in libpcre and other implementations I tried, I went and implemented my own is_utf8() function (plus unit test). I'd be happy to send you the function or the unit test if you want it.

Lookbehind assert (?<=) error in pcre_dfa_exec

Anonymous — Mon, 26 Mar 2007 14:47:10 -0000

This can work:
////////////////
re> /(?<=a)b/
data> ab
0: b
///////////////

But this can not:
///////////////
re> /(?<=a)b/
data> a/P/D
No match
data> b/R/P/D
No match
///////////////

I think the second one should also get matched.

PHP Segmentation Fault on PCRE preg_match_all()

Anonymous — Mon, 26 Mar 2007 11:53:57 -0000

Good Morning,
we're getting a Segmentation Fault error calling preg_match_all() in PHP 4.4.6 (that uses PCRE 7.0).

Perhaps you can help us solving this problem. I post the PHP BUG url:

http://bugs.php.net/bug.php?id=40909

Thank you in advice

PCRE Bug or Smarty Bug?

Ruud Boon — Sun, 04 Mar 2007 12:13:41 -0000

Hi,

After upgrading to version 7.0 of PCRE smarty for PHP stops working. The only way to get it working again is downgrading PCRE.
Smarty stop responding on this line :
preg_match_all('~\|(@?\w+)((?>:(?:'. $this->_qstr_regexp . '|[^|]+))*)~', '|' . $modifier_string, $_match);
There's a topic on http://www.phpinsider.com/smarty-forum/viewtopic.php?t=10467
Is this problem smarty related or PCRE? S
marty works fine with version PCRE 6.6_1. It's running on freebsd6 with apache2 and php5.2

With regards,

Ruud Boon

Subroutine bug with certain patterns.

Apostolos Lerios — Mon, 29 Jan 2007 22:09:36 -0000

Below is the pcretest output (7.0 version):

* The first pattern works correctly: a|(ab) matches both 'a' and 'ab'.

* The second pattern also works correctly:
(a|(ab)) | ( y(a|(ab)) )
matches 'a', 'ab', 'ya', 'yab'.

* Trouble starts with the third pattern, when a subroutine is used for a|(ab): now the string 'yab' doesn't match (but should).

* Trouble remains when using a named subroutine.

* All's fixed if the a|(ab) is changed to (ab?).

Seems like a lookahead problem in the context of subroutines, with maybe caching in the mix...

BUG using the pattern "\s"

bertrand db — Thu, 11 Jan 2007 09:22:28 -0000

Tested with PCRE 6.7 -> 4.5

when replacing an utf-8 string containing the character 'à' (hex: c3a0)
With the function preg_replace, and the pattern '\s', it changes the
second byte of this character.

Using the pattern ' \t\f\r\n' which is supposed to be the same as \s it
works perfectly.

I have tried with other utf-8 characters and it seems to work.

Reproduce code:
---------------
<?
$text = utf8_encode("this is a test àt");
echo bin2hex($text)."\r\n";
$text1 = preg_replace("'([\t\f\r\n])+'", " ", $text);
echo bin2hex($text1)."\r\n";
echo $text1."\r\n";;
$text2 = preg_replace("'([\s])+'", " ", $text);
echo bin2hex($text2)."\r\n";
echo $text2;
?>
