## #46714 — Bruce Bailey — 2010-01-13T23:55:04+00:00

Help!

I was patching out a new version of my PHP extension, with a different version as part of the name:

libmyext.so.1.0 is now libmyext.so.2.0

I updated php.ini (extension=libmyext.so.2.0) and restarted apache with the graceful option.  For some reason, both extensions were loaded simultaneously -- as reported by 'lsof'

What's going on here?  I don't get this behavior on other systems that have the same level of PHP and Apache.

apache version 1.3.37

PHP version 5.2.3



Thanks,

Bruce

lsof might be wrong or you need to stop&start your apache.
In any case, you should have used ldd instead of lsof.

> apache version 1.3.37 
> PHP version 5.2.3

Btw, it's time to upgrade these.

Antony

Thanks very much for your reply.  And yes, you're right, it IS time to upgrade.

Unfortunately, ldd only shows shared libraries that are automatically loaded.  My php extension is loaded by dlopen, which is not shown by ldd.

I used lsof because it shows all DSO libraries that are loaded, regardless of how they are loaded.  I was not aware that lsof was likely to be wrong.

I guess that my only recourse is to stop and start apache, and not use 'graceful' at all.

Again, thanks for your reply.

Bruce

ldd /path/to/your/extension
This is what I meant, of course.
