Bug #76899 [ReO]: pcntl_async_signals not available in phpdbg

Edit report at https://bugs.php.net/bug.php?id=76899&edit=1 ID: 76899 Updated by: cmb@php.net Reported by: kaplun at protonmail dot com Summary: pcntl_async_signals not available in phpdbg Status: Re-Opened Type: Bug Package: phpdbg Operating System: CentOS 7 PHP Version: 7.2.10 Block user comment: N Private report: N New Comment: > I am trying to connect a GitHub PR to this issue, but the > bug-tracking is giving me error 500 :-( Known issue[1], unfortunately still unresolved. > ... and my PR meanwhile failed on Travis.

I'm not sure why, though. There may be actual issues with running pcntl under interactive phpdbg, but running with -qrr might be fine (and should be supported if so).

I've just build with `./configure --disable-all --disable-cgi --enable-debug --enable-pcntl` and ext/pcntl is available for phpdbg (without the PR). ------------------------------------------------------------------------ [2018-09-18 12:55:26] kaplun at protonmail dot com P.s. Thanks cmb@php.net for the pointers! ------------------------------------------------------------------------ [2018-09-18 12:54:39] kaplun at protonmail dot com I am trying to connect a GitHub PR to this issue, but the bug-tracking is giving me error 500 :-( So the PR is here: https://github.com/php/php-src/pull/3534 ------------------------------------------------------------------------ [2018-09-18 12:04:34] kaplun at protonmail dot com > The php.ini you see is actually provided by way of php7.2-common's php.ini-production. We > can't do anything for it. This is true for Ubuntu. On CentOS7/Webtatic instead they are not explicitly disabled, and that what leads to: [Uncaught Error in /tmp/test.php on line 2] Error: Call to undefined function pcntl_async_signals() in /tmp/test.php:2 Stack trace: #0 {main} So either webtatic "forgot" to enable pcntl_async_signals during phpdbg compilation, or there's a general reason why this can not be available in phpdbg at all, which bring me to the reason why opened the bug report in the first place: there's no documentation around stating that phpdbg does not support pcntl_async_signals (at least I wasn't able to find it), however both on CentOS and Ubuntu this is not an available feature (either not compiled in, or explicitly disabled). Is this: * a bug (for CentOS/Ubuntu) * a missed documentation (for PHP.net as a whole and/or phpdbg) * a missing feature (for PHP.net as whole and/or phpdbg) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
