NGINX has technically said this is won't fix:

There are no immediate plans.

When we last checked, there were no problems with PCRE, but PCRE2 
wasn't available in most distributions we support, making the 
switch mostly meaningless.

Also, it looks like PCRE2 is still not supported even by Exim, 
which is the parent project of PCRE and PCRE2:

https://bugs.exim.org/show_bug.cgi?id=1878

As such, adding PCRE2 support to nginx looks premature.

Indeed, same for zsh:

checking for pcre-config... no
checking pcre.h usability... no
checking pcre.h presence... no
checking for pcre.h... no
checking for pcre_compile... no
checking for pcre_study... no
checking for pcre_exec... no
[...]
../../Test/V07pcre.ztst: starting.
../../Test/V07pcre.ztst: skipped (the zsh/pcre module is not available)

→ Back to Incomplete. I'll revert that commit from the recent 5.6.2-2
  upload.

I think that completes the analysis of the current state of things.
Although it seems infeasible to demote PCRE at this time, there’s no
reason that should block the promotion of PCRE2, especially seeing as a
bundled copy of PCRE2 is already in main (18.04 and 18.10) via
libqt5core5a.

Note to those filing upstream bugs: probably don’t call the old library

Actually, sssd build would still pull libpcre3-dev because of some
dependency, and then use that... and upstream config phase doesn't
support pcre2. I've filed a bug upstream.

[Bug 1792544] Re: demotion of pcre3 in favor of pcre2

2018-09-18 Thread Anders Kaseorg
Andreas: No, it’s not a bug.  PCRE2 is a new project that’s not intended
to be compatible with the older PCRE (i.e. what Debian misnamed
“pcre3”).  The API is completely different and this is expected.  See
bug 163 for context, and specifically the PCRE2 release announcement
linked in the bug description:

https://lists.exim.org/lurker/message/20150105.162835.0666407a.en.html

That’s why getting rid of PCRE “in favor of” PCRE2 is a pointless way to
frame the issue.  PCRE2 neither replaces nor conflicts with PCRE, as was
pointed out many times in bug 163.

But since we’re apparently gathering information here: although Apache
2.4.x does not support PCRE2, Apache trunk does support PCRE2 as of
r1773454.  (As you can see, this support was added by creating separate
conditionally compiled code paths for PCRE and PCRE2.)

2018-09-18 Thread Andreas Hasenack
I've seen the wget debian change, but just switching builddeps from pcre3-dev 
to pcre2-dev and rebuilding isn't enough. The package ends up not finding pcre 
and doesn't enable it:
checking for PCRE... no
checking pcre.h usability... no
checking pcre.h presence... no
checking for pcre.h... no
...
  Libs:  -luuid -lidn2 -lnettle -lgnutls -lz -lpsl 

So while the package builds, it's not using pcre.

I tried to switch apache, and while I could make it find pcre2-config and use 
it, pcre2 has different libraries than pcre3:
pcre3-config --libs: -lpcre
pcre2-config --libs: no such parameter

In pcre2, we have --libs8, --libs-posix, --libs32 and --libs16, but no
--libs. Is this a bug in pcre2-config?

Any quick tips about this before I dig in further?

zsh in Debian Unstable (5.6.2-1) seems to build fine if I exchange
libpcre3-dev by libpcre2-dev in Build-Depends and Build-Using (via
debian/rules).

** Description changed:

  demotion of pcre3 in favor of pcre2. These packages need analysis what
  needs to be done for the demotion of pcre3:
  
  Packages which are ready to build with pcre2 should be marked as
  'Triaged', packages which are not ready should be marked as
  'Incomplete'.
  
  aide
  apache2
  apr-util
  clamav

  freeradius
  git
  glib2.0
  grep
  haproxy
  libpam-mount

  postfix
  python-pyscss
  quagga
  rasqal
  slang2
  sssd
  wget

+ For clarification: pcre2 is actually newer than pcre3.  pcre3 is just
+ poorly named (according to jbicha).
