i have noticed the MSHUTDOWN function of my extension isn't called if the
.so in memory is different than those in disk. this can happen if i release
a new .so and restart apache. for example, i observed the following:
- cp .so to my extension dir
- start apache
- cp a new .so to my extension dir with bug fix
- stop apache
- start apache
for some reason, in step 4, the module's MSHUTDOWN function isn't called at
all. the following, however, works fine:
- cp .so to my extension dir
- start apache
- stop apache
- cp a new .so to my extension dir with bug fix
- start apache
the only differences is that in the second version, i stop apache before
copying the new .so over. why does it matter? step 4 of my first version
should have unloaded the old .so from memory and then picks up the new .so
in step 5, but it's not doing that. does anyone know why?
