Subject: streams problem in 5.3
From: smalyshev@sugarcrm.com (Stas Malyshev)

Hi!

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?
