Support the PHP extension under Windows
---------------------------------------
Key: TUSCANY-1133
URL: https://issues.apache.org/jira/browse/TUSCANY-1133
Project: Tuscany
Issue Type: Improvement
Components: C++ SCA
Affects Versions: Cpp-current
Reporter: Caroline Maynard
Priority: Minor
Fix For: Cpp-current
I've been battling with getting this working under Windows, and attach a patch
with my latest efforts. Note that these changes work hand-in-hand with
corresponding changes to the Tuscany bindings for PHP SCA, which are already in
place in the AVOCET branch in the PECL repository.
On my Windows box with the patch installed, the PHP Calculator sample runs
clean, with no crashes on shutdown and no reported leaks of PHP memory.
I've also done quite a bit of tidying up, to make the inner workings a more
standard use of the PHP engine. In particular, I've broken out the big
php_eval_script() into its component parts, which makes it much easier to
debug. Unfortunately I haven't had time to refactor
SCA_TuscanyWrapper::invoke() subsequently, so it is rather a long sprawl at
present and could do with further prettying. I also hid the SCA_Tuscany object
handle from user space, because exporting the handle as a reference was rather
dangerous code.
One thing I haven't yet tackled is getting the thread context right for
reentrant paths through the extension. I've been investigating this, and I
think it's going to require saving a thread context in each of the mediator
objects, and restoring the correct one on invoke(). However what's there seems
to work OK in the simple environment of the PHP Calculator sample.
I'm out for a few days now - could someone give it a spin on *IX and make sure
that's still OK?
