Bug #76086 [Opn]: Unable to write to php://stderr

Edit report at https://bugs.php.net/bug.php?id=76086&edit=1 ID: 76086 Updated by: bukka@php.net Reported by: chris at modd dot com dot au Summary: Unable to write to php://stderr Status: Open Type: Bug -Package: Streams related +Package: CGI/CLI related Operating System: * PHP Version: 7.2.3 Block user comment: N Private report: N New Comment: This is up to SAPI to handle correctly. FPM has got a logic around this so this really seems to me like a CGI sapi related problem which is what I assume is used here. There is not much that can be done on stream level. Previous Comments: ------------------------------------------------------------------------ [2020-09-22 09:15:02] cmb@php.net > Used to work fine in PHP 5.x. Not with PHP 5.6.40 on Windows. Actually, this doesn't look like a Windows specific issue to me, but rather depends on whether stderr is actually writable. Since php://stderr does not refer to the multiplexed FCGI standard error stream[1], there may be no stderr at all. See also bug #79905.

That would be great, since we prefer to have a PHPT regression test to go along with the actual bug fix, anyway. ------------------------------------------------------------------------ [2018-03-14 21:25:00] aharvey@php.net I can't reproduce this on Linux, so this looks Windows-specific. ------------------------------------------------------------------------ [2018-03-14 21:09:27] chris at modd dot com dot au I am ONLY using the libfcgi0ldbl as a stand-in for running a webserver. It fails exactly the same way using Apache with fastcgi, nginx with fastacgi and using a PHP fastcgi client. If you prefer I can write an example that uses the fcgi client used by the php unit tests. https://github.com/php/php-src/blob/master/sapi/fpm/tests/fcgi.inc using the cgi-fcgi package just means the example is simple to try and run and with Bash for windows, its easy enough to run it on windows too. ------------------------------------------------------------------------ [2018-03-14 17:23:08] ab@php.net Thanks for the further info. libfcgi0ldbl is not a package from the PHP distribution. It is also unlikely available on Windows. Thus, seems it's not a PHP bug. From what is shown, i guess it's about the port doesn't get reused or similar. If there's a repro regarding PHP, please post, otherwise it's probably to be marked as not a bug. Thanks. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
