The patch in question can be found here:
http://www.php.net/~jani/patches/exts_loading_poc.patch
It is merely a quick proof-of-concept:
a) Separates PHP extension registering and startup routines
b) Adds an extra 'depends' entry to the module struct
c) Nukes the problematic AWK script (just for debugging so that I got
'wrong' order :)
If an extension has no dependancies, it will be registered and started
in same loop. If it has dependancies, it is registered but the startup
routines are not run. When all extensions are loaded and registered,
the startup routines are run for all the extensions (if one is already
started it's just skipped).
That patch needs a bit tuning up before it can be applied, given the
concept is approved, of course. :)
Needs to be done:
- All extensions requiring something from other extensions need to be
updated to have the deps in their module entry
- php_startup_extensions() needs to be more intelligent and loop through
until all dependancies are met and not just blindly try starting up
anything before extensios it depends on are started
- Make it quicker. I haven't done any benchmarks but it's pretty obvious
this does make the PHP startup slower..

I think it would be a strong addition.

That patch of mine to the extension loading mechanism should fix this?
Just add a dependancy of spl to pdo..and fix the 'delayed' startup
routine. :)

Hello Wez,
we could check if spl is initialized and if not forcefully initialize it
in pdo's MINIT.

Modified files:

Log:
"Fix" PECL #4411
SPL is not initialized before PDO, so inheriting from SPL's runtime
exception class gives PDO a broken exception class.
We don't currently have a way to express this kind of "soft"
dependency in the build system, so I'm disabling inheriting from the
runtime exception for now.
