I try to do some complex code with custom streams and I have discovered
the following problem:
The code in main/streams/cast.c, specifically _php_stream_cast, creates
fopencookie() synthetic stream for streams that are not actual file
streams. Which works fine until such stream is used in include(), in
which case it ultimately arrives at zend_stream_fixup(). Which would in
turn call zend_stream_fsize() - which would do
fstat(fileno(file_handle->handle.fp), &buf) - and that would fail since
you can't get fileno for FILE* created by fopencookie.
Which ultimately means I can't use my custom streams for include(),
which is bad. Now, looking at the code, it doesn't actually need the
exact size - http streams can be included just fine - but insists on
having it if it has fp (which it can have for basically any kind of
stream due to the cookie trick). Does anyone has any idea why and if it
can be fixed?
Can you tell what exactly you're doing? Why is there any cast in the first
place?
As far as I can see, the include should eventually call
php_stream_open_for_zend_ex, which should give a ZEND_HANDLE_STREAM file
handle that defers reading to _php_stream_read and fsize to
php_zend_stream_fsizer, with no casting involved.
