Description

After updating from PHP 5.6.8 to PHP 5.6.9 (http://php.net/ChangeLog-5.php#5.6.9), I am encountering these errors:

Typo3 7.2.0 (installtool or backend):

#1: PHP Warning: preg_match(): Compilation failed: internal error: previously-checked referenced subpattern not found at offset 1963 in typo3_src-7.2.0/typo3/sysext/fluid/Classes/Core/Parser/TemplateParser.php line 811

TYPO3\CMS\Core\Error\Exception thrown in file
typo3_src-7.2.0/typo3/sysext/core/Classes/Error/ErrorHandler.php in line 102.

(frontend):

Oops, an error occurred!

Typo3 6.2.12 (backend, installtool):

#1237900529: The argument "arguments" was registered with type "array", but is of type "string" in view helper "TYPO3\CMS\Fluid\ViewHelpers\RenderViewHelper" 

InvalidArgumentException thrown in file
/var/www/wrs.0711cms.de/typo3_src-6.2.12/typo3/sysext/fluid/Classes/Core/ViewHelper/AbstractViewHelper.php in line 385.

I suspect the PHP-upgrade to pcrelib 8.37 being the cause of the Typo3 7.2-error. For the other, I really have no idea.

The 6.2 error sounds more like a syntax error in some Fluid template.
Where do you get this error? Upon login?
Can you maybe provide a full stacktrace?

Seems to be a bigger issue:

https://github.com/swiftmailer/swiftmailer/issues/259

In 5.6.9 the PCRE Version was updated to 8.37 (http://php.net/ChangeLog-5.php#5.6.9) and this does not seem to play well with the swiftmailer regex.

I suspect that regex-based parameter-parsing is the cause of the 6.2-issue, too.

As this happened on a live system, I quickly reverted to the older PHP-version.

Strange thing: in the currently downloadable PHP 5.6.9 http://php.net/get/php-5.6.9.tar.bz2/from/a/mirror pcre 8.36 is included, not 8.37 as announced. At least it looks like that in these files:

php-5.6.9/ext/pcre/pcrelib/config.h:317:#define PACKAGE_STRING "PCRE 8.36" 
php-5.6.9/ext/pcre/pcrelib/config.h:326:#define PACKAGE_VERSION "8.36" 
php-5.6.9/ext/pcre/pcrelib/config.h:442:#define VERSION "8.36"

I compared this with pcre's source ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/ and upstream clearly states version 8.37 in these places.

I could verify on a test server (with Ubuntu, not Debian as the live system) that the problem actually does not exist with this PHP for both Typo3 v7.2.0 and Typo3 v6.2.12. This PHP is the official current PHP-5.6.9.

So to be honest I am very puzzled right now: PHP 5.6.9 does not include pcrelib 8.37 as announced (but maybe it did in an earlier download?) and I had an error that I cannot reproduce with freshly downloaded sources.

I had the error on Debian Wheezy with PHP-packages from

deb http://packages.dotdeb.org wheezy-php56 all

. Unfortunately I do not have a Debian wheezy test system here where I could quickly verify. It could very well be that the problem comes down to Debian PHP patches.

Or PHP quickly withdrew pcrelib 8.37, reverted and reuploaded without version change? ;)

So maybe someone could try on a Debian to verify.

dmaicher mentioned in this ticket that swiftmailer works fine in php-cli and is broken when using Apache.

Can you please verify whether this is your case, too?

Looking in the git history of PHP shows that on branch PHP-5.4 was an zupdate from pcre 8.34 to 8.36

    Upgrade PCRE to 8.36, it fixes some crashes

    We probably will need to go to 8.37 once it is released.

This was merged successive to PHP-5.5, PHP-5.6 and master. After this there was a new commit.

commit 95fa72799298300f310c630a6c854f511d083bcc

    Upgrade to PCRE 8.37 due to various bugfixes

which was also merged into the branches PHP-5.5, PHP-5.6 and master.
This second commit doesn't changed config.h of pcrelib, thats why pcrelib states it uses 8.36 instead of 8.37 and maybe they forgot more.

Same issue here with Typo3 7.2, Debian 7.8 and latest PHP 5.5.25 release

Curiously changelog 5.5.25 does not mention anything regarding regex, but PHP 5.4.41 got PCRE 8.37 as well!

Hence I suspect that the changelog for 5.5.25 forgot to mention the PCRE changes and even worse 5.4.41 is affected too!

Major problem: All PHP updates were security updates and all of them break Fluid!

OK. Since the original debian packages run with 5.6.7 and not 5.6.9 they are not yet affected, that's the reason the solution worked for me.

Just updated my Fedora 21 dev server.

# php -info
PHP 5.6.9 (cli) (built: May 15 2015 09:17:14)
PCRE Library Version => 8.35 2014-04-04

Seems that Fedora is shipping an even lower version of PCRE.

Same here. Just tried updating php to the yesterday-released dotdeb versions: The PCRE Library is now reported as 8.36. The TYPO3 errors are still there.

$ apt-cache policy php5 | grep Installed
Installed: 5.6.9-1~dotdeb+7.2

$ php -info | grep 'PCRE Library'
PCRE Library Version => 8.36 2014-09-26

I'm on Debian Wheezy with all packages up to date and (trying to) use TYPO3 CMS 6.2.12.

@Ludwig Rafelsberger

The PCRE Library version should be reported as 8.37. So the 5.6.9-1 package do not have this patch included. Normaly this change will be in 5.6.10.
But I don't know if only fixing version number fixes this issue.

Since we seem to have figured out it's a problem with that pcre-version: Do you think there is simply a bug in pcre (which will be fixed) or was there some change we'd need to take care of to keep things working with newer php/pcre-releases?

It works with 5.6.9 on Fedora 21 here, so I don't think it's a bug in PCRE, but rather something in the debian packages.

Imo the problem is located in the PHP lib, can we can do anything in the core? If not, I would prefer to remove this issue from the Stab-Board.

Target version deleted (~~6.2.13~~)
Sprint Focus deleted (~~Stabilization Sprint~~)

We can do nothing in Core! I already checked the regex, no sane way.

It works on lower PHP versions and on current versions on non-debian. So IMHO this needs to be fixed there.

As it looks like, the issue only happens with php5_mod and not PHP cli we can do nothing here.
Maybe php5_mod collides with the false PCRE version number in latest PHP 5.x versions, so this should be controlled again if it is solved with PHP 5.6.10, 5.5.26, 5.4.41. If not, we can only open an issue report in PHPs bug tracking system.

I can also confirm that the previous 5.5.24-1~dotdeb+wheezy.1 from dotdeb works.

It really seems that just the very latest dotdeb-Packages (5.6 and 5.5) are affected.

Do we have a simple testcase to reproduce this? Something to quickly run in the CLI or on a blank website to check? That way I could quickly produce a list of works/works not and recheck on PHP compiled from source.
