This only adds PCRE2 support to YAJL, correct?

[khiemdoan]

@theseion no, this adds PCRE2 to libmodsecurity follows the comment owasp-modsecurity/ModSecurity#2719 (comment),
you can try to see it already linked to pcre2:

ldd /usr/local/modsecurity/lib/libmodsecurity.so
    linux-vdso.so.1 (0x00007fff60dc6000)
    libcurl-gnutls.so.4 => /usr/lib/x86_64-linux-gnu/libcurl-gnutls.so.4 (0x00007fe2e8361000)

Nginx 1.21.x is not stable. And I don't know if we should go for 1.22.0 yet...

[theseion]

@khiemdoan ah yes, sorry.
We had a discussion on Slack about PCRE2 a couple of weeks back. I'm pretty sure that not everyone will want to switch to PCRE2, at least not immediately. So we might have to consider producing two variants for the two PCRE versions.

[khiemdoan]

@theseion I agree with you that we should have two versions for testing and comparing.

[khiemdoan]

@fzipi I have tested with nginx 1.22.0, it runs without any problem. Let me make a commit.

[fzipi]

Thanks Kiem. We are aware that we still have this one, we need more time to think how are we going to tag them.

[fzipi]

Approving this one instead of #131 .
