[Mapserver-dev] Testing thread-safety

[Jean-Francois.Doyon at CCRS.NRCan.gc.ca]

G'Day,

Daniel mentionned to me that thread safty should be fairly complete, though
untested, in CVS.

So, I'm trying to compile MapServer CVS with PHP 4.3.3, with all of them as
modules.

Not having much luck though!

First MapServer seems to mis-detect the regex setting on my PHP, even though
it's compiled with --with-regex=system, I get ugly errors (See at the end of
this message).  Apparently "configure" tests for the existence of "define
REGEX 1" ... The funny thing is that this is true whether I compile PHP with
"system" or "php" regex's !! The only way for this NOT to be true so far is
to use the "apache" regex setting ... Which I didn't do.

For now I've hacked the configure script to pretend like the test works,
even when it doesn't :)

Any ideas on what's going on here ? Is the PHP regex implementation
sensitive to whether it's a module or not maybe ? Could I use "apache" for
now, if only just for testing ?

I haven't gotten there yet, but I've also obviously hacked the test for apxs
to by-pass that.  I've built mapserver with --with-threads also.  Will this
be enough ?

Any insight would be much appreciated :)

Here's the regex related error when using --with-regex=system and bypassing
the test in configure:
