Description OlivierW 2020-01-12 10:11:01 UTC

Two years ago, I have helped enabling PCRE regexp in Squid's port, see #223505.
Back then I was using Squid 3.5.x on FreeBSD 11.x and it was fine :-)

Now, I am updating to Squid 4.9 on FreeBSD 12.1 and PCRE regexp don't work anymore, I am getting back the error message I previously had before #223505 : "repetition-operator operand invalid".
I've also tried to install squid3 (3.5.28_3), and got the same error.

The good news, I have found I need to add:
at the end of CONFIGURE_ARGS= in the port Makefile.
This option is documented here: https://github.com/squid-cache/squid/blob/77b1029d207083d583d81d2f2fb7a840e0f23cab/configure.ac#L3615

It does fix my problem, but is it the right way to do it? I mean, in their explanation of the option, they say it is for Windows or old UNIX which don't have a regex lib.
Has anything has changed in FreeBSD 12 regarding regexp? Does anyone know why that happens?

I have tried compiling with and without the PCRE option added in #223505, and it does work in both case: this option seems useless with "--enable-gnuregex".

What should I do to help? Is it OK to directly add this "--enable-gnuregex" option to CONFIGURE_ARGS? Or should I add a configurable option?
I can provide a patch, I just need to know what is best to do :-)

Best Regards,
