PHP 5.4.11

January 24, 2013 · Guillaume Plessis

On january 17th 2013, the PHP group has released PHP 5.4.11 :

These releases fix about 10 bugs. All users of PHP are encouraged to upgrade to PHP 5.4.

The corresponding packages are now available on Dotdeb for Debian 6.0 “Squeeze” on both amd64 and i386 architectures, with these changes :

APC has been upgraded to 3.1.14
Xcache has been upgraded to 3.0.1 (now compatible with Ioncube)
mysqlnd headers are now included in php5-dev to allow mysqlnd plugins to build

As usual, please read the ChangeLog before upgrading and be sure to use to the latest packages before reporting any issue.

Note 1 : PHP 5.3.21 packages will be available at the end of this week. Note 2 : Including igbinary as serializer in PHP’s core and in the memcached and redis extensions is currently in progress.

Hans van Eijsden January 24, 2013
Whoaaa!!! What a great news: igbinary support included! This will make APC and memcache sessions WAY faster and smoother! Thank you very much for including igbinary. Info: http://phpolyk.wordpress.com/2011/08/28/igbinary-the-new-php-serializer/ I use igbinary to store my session data in memcached and I use igbinary as APC handler. Great performance gains! :)
- Guillaume Plessis January 25, 2013
  @Hans : igbinary support is just a WIP (and it’ll also be a great improvement, you’re right). I hope to release it with the next PHP packages.

FYI if upgrading to APC 3.1.14,
PHP may core dump if you have apc.lazy_functions and apc.lazy_classes enabled, which are options that were added in APC 3.1.13.

The script at “/usr/lib/php5/sessionclean” seems to be broken in this release. I’m getting emails from cron about lsof not being found (which was never installed on this system).
When trying to run the script manually, I get the following output: /usr/lib/php5/sessionclean: 4: lsof: not found find: warning: you have specified the -ignore_readdir_race option after a non-option argument -type, but options are not positional (-ignore_readdir_race affects tests specified before it as well as those specified after it). Please specify options before other arguments.
find: invalid argument -delete' to -cmin'
This occurs on a Debian 6 server.
- Guillaume Plessis January 26, 2013
  @packetwar : thanks for the feedback. I’ll introduce a dependency on lsof.
  - Michael January 31, 2013
    When will it happen? With 5.4.12 release or earlier?
    Wouldn’t it be too hard to make random minutes in /etc/cron.d/php5? $(($RANDOM % 30)) and 30 minutes later.
    - Guillaume Plessis January 31, 2013
      @Michael : already in git
      https://github.com/gplessis/dotdeb-php5/commit/612fc0e03046347ebaad7d27229836e747a12b55
      will appear in the next PHP packages (5.4.12 if no major flaw is dicovered in the current version).
      - Michael January 31, 2013
        Yes, I saw it. Just wanted to confirm my guess about 5.4.12.
        What about random minutes in cron?
    - Guillaume Plessis January 31, 2013
      @Michael : what’s the point with random minutes? Spreading/delaying the io on virtualized systems?
      - Michael February 6, 2013
        Yes, actually it is.
- ivy February 9, 2013
  Did you find a fix to this? I install lsof, but I’m still getting the “find: invalid argument -delete’ to -cmin’” error
Janusz Dziemidowicz January 27, 2013
For me, APC 3.1.14 is contantly segfaulting, with default configuration on Squeeze. After a few requests APC start to segfault more often than not.
- Shaun Hague January 28, 2013
  I’m getting Apache2 child seg faults too since installing the dotdeb PHP 5.4.11 package last night; APC 3.1.14, Libmemcached 1.0.13 and memcached 2.1.0
  Disabling APC stops the seg faults.
  - Shaun Hague January 28, 2013
    Update: I’ve upgraded libmemcached to 1.0.15 and the seg faults have stopped (and APC isn’t fragmenting anymore either).
    - Shaun Hague January 28, 2013
      Apologies - the libmemcached upgrade is a red herring, please ignore.
      I have since found (and tested) the problem - in apc.ini I had ‘apc.stat=0’ (default is 1) - when I changed back to the default value of 1 the seg faults disappeared.
ru_maniac January 27, 2013
Guillame, is it enough to just include 5.4’s repo in sources and then upgrade (in order to upgrade from dotdeb’s 5.3)? I just double-checked all dependencies, and it pretty much should be alright, but I decided that it’s worth asking.
- Guillaume Plessis January 27, 2013
  @ru_maniac : why more difficult? Yes, just upgrade with this new sources.list entry.
thomas January 28, 2013
hi with this http://chatme.im/phpinfo.php can i upgrade to php 5.4.x without problem or i must remove something?
- Guillaume Plessis January 28, 2013
  @thomas : yes, you can upgrade safely. Be sure to read the migration guide before : http://php.net/manual/en/migration54.php
Julius January 28, 2013
I upgraded yesterday but now I checked again and apc is 3.1.13. Did you changed anything? Thanks for your help!
- Guillaume Plessis January 28, 2013
  @Julius : I silently downgraded APC to the 3.1.13 version. 3.1.14 is buggy
Julius January 28, 2013
Alright, thank you!
Los Superktos January 30, 2013
I get still this bug with APC 3.1.13
Nestor February 20, 2013
Guillaume, please tell me:
1. Which version of the extension PECL/memcache is in the package named “php5-memcache_5.4.11-1~dotdeb.0_i386.deb”?
2. Extension php5-xcache has a web interface located in the “/usr/share/xcache/htdocs/” directory - ok. And it seems that extension PECL/memcache should have something similar - a file named “memcache.php” here: http://svn.php.net/viewvc/pecl/memcache/tags/RELEASE_2_2_6/ But I can’t find it after install php5-memcache. So, why is it missing? What’s wrong with my installation? Thanks in advance.
- Guillaume Plessis February 20, 2013
  @Nestor :
  1. memcache 3.0.7
  2. it’s missing. Download it from here : http://svn.php.net/viewvc/pecl/memcache/tags/RELEASE_2_2_6/memcache.php?revision=303962&view=co

session.gc_probability must be 1, as recommended. With 0, sessions could create million of files until you run out of partition inodes. After instalation: /etc/php5/fpm/php.ini ; Default Value: 1 ; Development Value: 1 ; Production Value: 1 ; http://php.net/session.gc-probability session.gc_probability = 0
- Guillaume Plessis February 21, 2013
  @Daniel Ghe : did you read the “session storage” section of https://github.com/gplessis/dotdeb-php5/blob/squeeze-php54/debian/php5-common.README.Debian ? A cron is doing the job.
Markus February 28, 2013
I have problems installing php54 from dotdeb.

  @Markus : try this :
```
 rm -f /var/lib/apt/lists/*
apt-get update
```
Markus February 28, 2013
Hi Guillaume,
I forgot to mention in my first posting that i already tried that approach as well. No change at all… I did it again… Result: Hole:25 http://packages.dotdeb.org squeeze-php54/all i386 Packages [9.650 B] Es wurden 29,8 MB in 1 min 5 s geholt (457 kB/s) Paketlisten werden gelesen… Fehler!

Markus February 28, 2013
Ok, now after doing a “apt-get –fix-missing update -o APT::Cache-Limit=100000000” I get this error message: Es wurden 29,8 MB in 1 min 5 s geholt (457 kB/s) Paketlisten werden gelesen… Fehler!

Markus February 28, 2013
Added your gpg key like explained here: /2010/07/11/dotdeb-packages-are-now-signed/ and called rm -f /var/lib/apt/lists/* apt-get update again No result.. :(
David March 1, 2013
Any update on the 5.4.12 PHP version? http://php.net/archive/2013.php#id2013-02-21-1
- Guillaume Plessis March 1, 2013
  David : I’m working on it. I’ll release 5.4.12 and 5.3.22 at the end of this week. I didn’t have much spare time these days, sorry.
  - Pascale Beier March 1, 2013
    Thank you, I was just about to ask for PHP 5.4.12 - Keep up the good job!
