Description Michael Seevogel 2017-07-06 05:39:18 EDT
Description of problem:
Newer PHP Applications like TYPO3 >= 8.7.3 demand a newer PCRE Version to work.¹
With other words: It's impossible to set up a >= TYPO3 8.7.3 Website on EL7.
The PHP Project also recommends newer PCRE Versions than 8.32 in conjunction with PHP >= 5.5.10 ²

I am aware that EL7 actually only ships with PHP 5.4, so I could understand that updating PCRE is not a priority (or not wanted), but there are alot of EL7 Webservers which do run also newer PHP Versions, like PHP 7 for example from Remi's Repo.

So the questions is: Are there any intentions to raise the PCRE Version for EL7 (perhaps even for EL6?), or are there intentions from EPEL or Remi Repo maintainers to provide newer PCRE Versions?

Currently it's just impossible to install an enterprise CMS like TYPO3 8.7.x on EL7 without to use a self-compiled RPM of PCRE >= 8.38.

You can use Red Hat Software Collections <https://www.redhat.com/en/resources/red-hat-software-collections> that provide Red Hat-supported PHP 7.0.10. For more details please contact Red Hat support.

To answer your question: no, there is no plan to upgrade pcre package in RHEL-7. 

Maybe you could be interested in PCRE2 that is heading to RHEL-7.4. PCRE2 is a new implementation of PCRE and any new piece of software should use that instead of the old PCRE.

PCRE2 will replace PCRE in RHEL-7.4?

If yes, then this is a good news, but if not, the problem with the old PCRE Version will still remain.

httpd is using through the configure flag the old PCRE Version.
If I would like to use as of today a newer PCRE Version the only two current options are:

  1. Recompile httpd to use PCRE2
  2. Replace PCRE with a newer and recompiled version from Fedora

Both options are rather bad considering that we are talking about a LTS binary distribution. In short term both of these options might do the job, but again, this could be, if at all, only a temporary solution.

I am pretty sure that this situation will arise more and more also for other customers/users of EL7 so I hope this will lead somehow and on someway to a solution.

No, it won't. They will be both.
