All,
It looks like mod_jk ships a copy of the PCRE library in source form
to be used inside of Microsoft IIS. It's using PCREv1 8.45 which is
the "latest version" of a library that was abandoned over 10 years ago.
Is anyone interested in looking into upgrading mod_jk's use of PCRE to
PCREv2?
(Related, the NOTICE file points the reader to the missing iis/pcre/
LICENSE file.)
I think it is a valuable goal. Probably looking at server/util_pcre.c in
the httpd source code (branch 2.4.x or even trunk) helps, because it is
likely the origin of our implementations of the ap_reg*() functions in
iis/jk_isapi_plugin.c. The httpd source files use defines to keep the
code compatible with PCRE(1) and PCRE2. We don't need to, but having t
there makes it easier to compare old and new code.
We would also need to check, whether we can still build PCRE2 on Windows
nicely. I think it was done with VisualStudio and PCRE2 still supports
it but I didn't try.
I can now build the isapi redirector on Windows. I will have a look into
the pcre2 migration. One subtlety is the build system. Our pcre
integration uses a handwritten small Makefile. Upstream pcre2 for
Windows supports cmake and autotools builds with cygwin or mingw32.
Since the pcre2 build is relatively easy, I will see, whether I can
adopt the handwritten Makefile to pcre2. That would then not support the
full build flexibility pcre2 has but simply make a well-defined build
for out own use in the redirector.
Best regards,
Rainer
