Description Petr Pisar 2021-03-15 11:59:30 UTC 
This is a kindly hint that zsh-0:5.8-4.fc34 still uses PCRE library which has been superseded with PCRE2 project by PCRE upstream in 2015. PCRE upstream considers PCRE obsolete now and does not devote any resources to PCRE except of critical bugs. Please consider porting zsh from PCRE to PCRE2.
Comment 1 Kamil Dudka 2021-03-24 15:39:22 UTC 
The dependency was introduced with the following commit (bug #1438009):

    https://src.fedoraproject.org/rpms/zsh/c/3174c77c

I do not have free capacity to handle the migration myself.

Jason, what is your take on this?
Comment 2 Jason Tibbitts 2021-03-24 16:35:13 UTC 
It would have been nice had I included a bug reference in the changelog.  But for the record, these modules were requested here: https://bugzilla.redhat.com/show_bug.cgi?id=1438009

Will have to see what other distros are doing.  Worst case, we just drop the module, but the primary issue is that at least in 2017 some shipped completions (particularly systemd) actually used pcre and tab completion would spew errors if it was missing.  I'm not sure if that's currently the case, though.
Comment 3 Jason Tibbitts 2021-03-24 16:41:29 UTC 
A quick look at Debian and Arch indicates that they have not moved away from using the old pcre library.

Since the software is still maintained upstream (as the report here says they are still fixing critical bugs) I don't see any pressing need to remove functionality, though upstream should of course be encouraged to port to the new library.  I personally have no idea how much effort is involved in porting from one library to the other.

Hi, do you have any update on this?
Comment 7 Lukáš Zaoral 2023-06-01 15:30:13 UTC 
Hello,
I'm waiting for a new upstream release now.  The pcre module was migrated to pcre2 last month with this upstream commit: https://sourceforge.net/p/zsh/code/ci/b62e911341c8ec7446378b477c47da4256053dc0/

Regards,
Lukas
