A review of the servlet.c send method shows the following code:
/*
* Parse the file
*/
SETSTRING( SG(request_info).path_translated,
pathTranslated );
#ifdef VIRTUAL_DIR
retval = php_fopen_primary_script(&file_handle TSRMLS_CC);
#else
/*
* The java runtime doesn't like the working directory
to be
* changed, so save it and change it back as quickly
as possible
* in the hopes that Java doesn't notice.
*/
getcwd(cwd, MAXPATHLEN);
retval = php_fopen_primary_script(&file_handle TSRMLS_CC);
chdir(cwd);
#endif
if (retval == FAILURE) {
php_request_shutdown((void *) 0);
php_module_shutdown(TSRMLS_C);
ThrowIOException(jenv, file_handle.filename);
return;
}
Relying on timing to make something work is usually not a good
practice and it looks like this code may not be working in my case due
to bad timing. As previously posted I'll try an earlier version of PHP.
