Status: Open
-Bug Type: Session related
+Bug Type: Documentation problem
Operating System: any
PHP Version: 4.3.10, also 5
New Comment:
This is actually just documentation problem:
You can't send any headers from a register_shutdown_function() call.
Or use any functions in such function that might send headers..such as
almost any session function.

Tiny example, that always reproduces the bug.
<?
ini_set('session.use_cookies', 0);
session_id('1234');
session_cache_limiter('public');
session_start();
session_write_close();
?>
text
<?
function a(){
session_cache_limiter('none');
session_start();
session_write_close();
}
register_shutdown_function('a');
?>
If just call a() at the end -- no warnings, if a() called at shutdown
-- warning issued.

No, we don't use this at all, this option is always set to 0.
Just checked, ini option is set to 0, .htaccess doesn't change this
option.

Do you have 'session.auto_start' set on somewhere?
(httpd.conf, .htaccess file, php.ini..)

There is one more detail, I forgot to mention:
I couldn't kill warning message by calling @start_session() in line 45.
Is this because of warning message issued somewhere in calls from
session_start()?

Just viewd latest session.c from CVS repository. There are not much
changes between versions 4 and 5, so bug still remains in PHP 5.
Somewhere here:
static int php_session_cache_limiter(TSRMLS_D)
{
php_session_cache_limiter_t *lim;
// for some reason, this string fails
if (PS(cache_limiter)[0] == '\0') return 0;
// I cant understand all this file, but I think, problem is
// that value 'none' is not properly recognized or processed
if (SG(headers_sent)) {
char *output_start_filename =
php_get_output_start_filename(TSRMLS_C);
int output_start_lineno = php_get_output_start_lineno(TSRMLS_C);
if (output_start_filename) {
php_error_docref(NULL TSRMLS_CC, E_WARNING, "Cannot
send session
cache limiter - headers already sent (output started at %s:%d)",
output_start_filename, output_start_lineno);
} else {
php_error_docref(NULL TSRMLS_CC, E_WARNING, "Cannot
send session
cache limiter - headers already sent");
}
return -2;
}
for (lim = php_session_cache_limiters; lim->name; lim++) {
if (!strcasecmp(lim->name, PS(cache_limiter))) {
lim->func(TSRMLS_C);
return 0;
}
}
return -1;
}
