Expected result:
----------------
I'd expect that FD's don't leak.
Actual result:
--------------
every call adds another open FD.
I've traced this to main/main.c 2266
PHPAPI int php_execute_script(zend_file_handle *primary_file TSRMLS_DC)
{
...
...
> old_cwd_fd = open(".", 0);
...
VCWD_CHDIR_FILE(primary_file->filename);
...
...
zend_try {
...
retval = (zend_execute_scripts(ZEND_REQUIRE TSRMLS_CC, NULL, 3,
prepend_file_p,
primary_file, append_file_p) == SUCCESS);
} zend_end_try()
...
...
// close old_cwd_fd code
}
-- looks to me that the objective is to move the process into the directory
of
the script. I thought that moving the close of the FD to right after the
move
[VCWD-CHDIR_FILE()] would cleanup the open FD and it does, However why is
this
happening in the first place? I ran the same test on my OSX workstation
and
FD's don't accumulate.
