Bug #74211 [NEW]: pecl-apcu disables mmap when configure is called with --enable-apcu-mmap

From: f dot niepelt at mittwald dot de Operating system: Gentoo/openSUSE Tumbleweed PHP version: Irrelevant Package: *General Issues Bug Type: Bug Bug description:pecl-apcu disables mmap when configure is called with --enable-apcu-mmap Description: ------------ Hello, package affected should be PECL Apcu which does not seem to exist in the Package affected list. When calling ./configure --enable-apcu-mmap, the script decides to not use mmap, but when omitting that option it does use mmap. ./configure --help only documents disable-apcu-mmap, so either the documentation is wrong or the implementation because clearly "enable-apcu-mmap" is changing the behaviour in a neither expected nor documented way. PHP Version: 7.1.2 APCU Version: 5.1.8 Reproduced on Gentoo and openSUSE Tumbleweed. Greetings Fabian Test script: --------------- #!/bin/bash wget "https://pecl.php.net/get/apcu-5.1.8.tgz" tar xzf apcu-5.1.8.tgz cd apcu-5.1.8/ phpize ./configure --enable-apcu-mmap | grep "checking if APCu will use mmap or shm" Expected result: ---------------- checking if APCu will use mmap or shm... mmap Actual result: -------------- checking if APCu will use mmap or shm... shm -- Edit bug report at https://bugs.php.net/bug.php?id=74211&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=74211&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=74211&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=74211&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=74211&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=74211&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=74211&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=74211&r=needscript Try newer version: https://bugs.php.net/fix.php?id=74211&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=74211&r=support Expected behavior: https://bugs.php.net/fix.php?id=74211&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=74211&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=74211&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=74211&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=74211&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=74211&r=dst IIS Stability: https://bugs.php.net/fix.php?id=74211&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=74211&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=74211&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=74211&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=74211&r=mysqlcfg
