Hi,
I am trying to get a PHP 4.3.2 SAPI working on Windows.
I am using Visual Studio 6.0 and am using the Debug Release
(php4ts_debug.dll).
I can successfully get the CLI (phpCLI.c) version of PHP working just fine
using the same linking instructions as I do for my SAPI program.
My SAPI is heavily based off the thttpd sample SAPI.
Right now I am getting a "Microsoft Visual C++ Debug Library" assertion:
--- Begin Dialog Contents ---
Debug Assertion Failed!
Program: c:\work\out\bin\phpServerHarness.exe
File: fdopen.c
Line: 54
Expression: _osfile(filedes) & FOPEN
For information on how your program can cause an asserion
failure, see the Visual C++ documentation on asserts.
(Press Retry to debug the application).
--- End Dialog Contents ---
Here is the code from fdopen.c:
--- Begin Code ---
FILE * __cdecl _tfdopen (
int filedes,
REG2 const _TSCHAR *mode
)
{
REG1 FILE *stream;
int whileflag, tbflag, cnflag;
_ASSERTE(mode != NULL);
#if defined (_WIN32)
_ASSERTE((unsigned)filedes < (unsigned)_nhandle);
_ASSERTE(_osfile(filedes) & FOPEN); // <------------ THIS ASSERT
if ( ((unsigned)filedes >= (unsigned)_nhandle) ||
!(_osfile(filedes) & FOPEN) )
return(NULL);
#else /* defined (_WIN32) */
--- End Code ---
This is the stack at the time of the assert:

-- End Stack ---
The place where I "lose track" (in terms of understanding) of what's
happening is in:
_php_open_wrapper_as_file()
where it takes a phpstream returned from:
php_stream_open_wrapper_rel()
and does:
if (php_stream_cast(stream,
PHP_STREAM_AS_STDIO|PHP_STREAM_CAST_TRY_HARD|PHP_STREAM_CAST_RELEASE,
(void**)&fp, REPORT_ERRORS) == FAILURE)
to it. I don't really know "what" they're trying to do from then on, but
it goes through a few functions (see stack) and ends up at that assert.
The arguments to php_open_wrapper_as_file look correct (valid paths).
I know this is a long shot, but if anyone can help me -- give me some kind
of pointer on where or what to look for -- libraries, languages,
ThreadSafe versus not ThreadSafe -- I'd really appreciate it. I've been
stumped for days. I don't really know how to get more information on the
code I'm looking at.
thanks!
