Hi,
First, I don't know if this must be considered as a bug, because a lot
of features are not available during MINIT but it seems quite
inconsistent. I precise I'm using the 7.x master branch (I don't know if
it works on 5.x or not).
I am writing an extension where I need to read a file tree during the
MINIT phase. So, I am using php_stream_scandir() to read some
directories. At this time, php_init_stream_wrappers() has run, so I
consider stream wrappers are available.
Unfortunately, this is not true because stream wrappers register
resources in EG(regular_list), which is not initialized before
init_compiler() has run. If I call zend_hash_init(&(EG(regular_list)))
before calling php_stream_scandir(), it seems to works. But it is not
the solution because the hashtable is never destroyed and there are
probably other side effects. The same potentially applies to
EG(persistent_list).
So, does it mean that stream wrappers cannot be used during MINIT, or do
you know a workaround ? I can revert to the C stdio library but, for
portability reasons, I'd prefer using the plain wrapper. Every
suggestion is welcome.
Another suggestion to help detecting such issues : can we consider, in
_zend_is_inconsistent(), that a HashTable whose nTableSize is null is
inconsistent and raises an alert. An uninitialized HashTable generally
is filled with 0s. Today, using an uninitialized HashTable goes
undetected, even in debug mode (because HT_OK == 0), and is very hard to
track.
Regards
François
