Sysvsem in php 8.1

    Hey there! sysvsem is a default included with PHP, so the best way to see that is to create a PHP info page on your domain and then you'll see this when visiting that page in a browser: '--enable-sysvsem=shared' I did confirm this on a PHP 8.1 system - let me know if you need more details from my end!

    Using cPanel 110.0.5 and PHP 8.1 for my NextCloud instance. And 'sysvsem' seems to be missing. Extracting from the "phpinfo" page: PHP Version 8.1.18 System: Linux ******* 3.10.0-1160.88.1.el7.x86_64 #1 SMP Tue Mar 7 15:41:52 UTC 2023 x86_64 Build Date: May 2 2023 21:19:36 Build System: Linux hou-1 5.3.18-150300.59.98-default #1 SMP Thu Oct 13 08:52:00 UTC 2022 (dfcde7e) x86_64 x86_64 x86_64 GNU/Linux Configure Command: './configure' ... '--disable-sysvsem' ...
    When I open a terminal and type 'php -m' I get the following, with no 'sysvsem' listed: [PHP Modules] apcu bcmath bz2 Core ctype curl date dom exif fileinfo filter ftp gd gmp hash iconv imagick imap intl json libxml mbstring mysqli mysqlnd openssl pcntl pcre PDO pdo_mysql pdo_sqlite Phar posix readline Reflection session SimpleXML SPL sqlite3 standard tokenizer xml xmlreader xmlwriter xsl Zend OPcache zip zlib [Zend Modules] Zend OPcache

    @Barry Johnson - is it possible that has been added to the disabled functions on that machine? sysvsem is included by default and also enabled on cPanel machines in the standard configuration.

    Reviewed stuff in MultiPHP Editor under both tabs, and found nothing that references sysvsem
    . I have no /etc/cpanel/ea4/phpini_directives
    for custom directives. Didn't see anything in .htaccess.
    or .user.ini
    files related to it. I thought the Build Date (May 2 2023 21:19:36
    ) and Build System (Linux hou-1
    ) I posted earlier, indicates where, when, and how the code was built. And that's before the code gets to my machine. And I don't recall ever doing anything "special" to fiddle with what is installed on my machine, especially PHP-wise. Fwiw, here's the complete Configure Command from the PHPInfo()
    page so you can check everything that the packaging generation did - and didn't!? - do: './configure' '--build=x86_64-redhat-linux-gnu' '--host=x86_64-redhat-linux-gnu' '--program-prefix=' '--disable-dependency-tracking' '--prefix=/opt/cpanel/ea-php81/root/usr' '--exec-prefix=/opt/cpanel/ea-php81/root/usr' '--bindir=/opt/cpanel/ea-php81/root/usr/bin' '--sbindir=/opt/cpanel/ea-php81/root/usr/sbin' '--sysconfdir=/opt/cpanel/ea-php81/root/etc' '--datadir=/opt/cpanel/ea-php81/root/usr/share' '--includedir=/opt/cpanel/ea-php81/root/usr/include' '--libdir=/opt/cpanel/ea-php81/root/usr/lib64' '--libexecdir=/opt/cpanel/ea-php81/root/usr/libexec' '--localstatedir=/opt/cpanel/ea-php81/root/var' '--sharedstatedir=/opt/cpanel/ea-php81/root/var/lib' '--mandir=/opt/cpanel/ea-php81/root/usr/share/man' '--infodir=/opt/cpanel/ea-php81/root/usr/share/info' '--cache-file=../config.cache' '--with-libdir=lib64' '--with-config-file-path=/opt/cpanel/ea-php81/root/etc' '--with-config-file-scan-dir=/opt/cpanel/ea-php81/root/etc/php.d' '--disable-debug' '--with-password-argon2=/opt/cpanel/libargon2' '--with-pic' '--without-pear' '--with-bz2' '--with-freetype' '--with-xpm' '--without-gdbm' '--with-gettext' '--with-iconv' '--with-jpeg' '--with-openssl' '--with-zlib' '--with-layout=GNU' '--enable-exif' '--enable-ftp' '--enable-sockets' '--with-kerberos' '--enable-shmop' '--with-sodium=shared' '--with-libxml' '--with-system-tzdata' '--with-mhash' '--enable-fpm' '--with-fpm-systemd' '--libdir=/opt/cpanel/ea-php81/root/usr/lib64/php' '--without-mysqli' '--disable-pdo' '--enable-pcntl' '--disable-gd' '--disable-dom' '--disable-dba' '--without-unixODBC' '--disable-opcache' '--disable-xmlreader' '--disable-xmlwriter' '--without-sqlite3' '--disable-phar' '--disable-fileinfo' '--disable-json' '--without-pspell' '--without-curl' '--disable-posix' '--disable-xml' '--disable-simplexml' '--disable-exif' '--without-gettext' '--without-iconv' '--disable-ftp' '--without-bz2' '--disable-ctype' '--disable-shmop' '--disable-sockets' '--disable-tokenizer' '--disable-sysvmsg' '--disable-sysvshm' '--disable-sysvsem' '--without-gmp' '--disable-calendar' 'build_alias=x86_64-redhat-linux-gnu' 'host_alias=x86_64-redhat-linux-gnu' 'PKG_CONFIG_PATH=/opt/cpanel/ea-php81/root/usr/lib64/pkgconfig:/opt/cpanel/ea-php81/root/usr/share/pkgconfig:/usr/lib64/pkgconfig:/opt/cpanel/ea-openssl11/lib64/pkgconfig:/opt/cpanel/ea-libxml2/lib64/pkgconfig:/opt/cpanel/ea-libicu/lib/pkgconfig:/opt/cpanel/ea-oniguruma/lib64/pkgconfig:/opt/cpanel/libargon2/lib64/pkgconfig:/usr/lib64/pkgconfig' 'CFLAGS=-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic -fno-strict-aliasing -Wno-pointer-sign ' 'CXXFLAGS=-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic' 'KERBEROS_CFLAGS=-I/usr/include' 'KERBEROS_LIBS=-L/usr/lib64' 'OPENSSL_CFLAGS=-I/opt/cpanel/ea-openssl11/include' 'OPENSSL_LIBS=-L/opt/cpanel/ea-openssl11/lib -lssl -lcrypto -lresolv' 'CURL_CFLAGS=-I/opt/cpanel/libcurl/include' 'CURL_LIBS=-L/opt/cpanel/libcurl/lib64 -lcurl' 'JPEG_CFLAGS=-I/usr/include' 'JPEG_LIBS=-L/usr/lib64 -ljpeg' 'SASL_CFLAGS=-I/usr/include' 'SASL_LIBS=-L/usr/lib64' 'ARGON2_CFLAGS=-I/opt/cpanel/libargon2/include' 'XSL_CFLAGS=-I/opt/cpanel/ea-libxml2/include/libxml2' 'XSL_LIBS=-L/opt/cpanel/ea-libxml2/lib64 -lxml2' 'LIBZIP_CFLAGS=-I/opt/cpanel/ea-libzip/include' 'LIBZIP_LIBS=-L/opt/cpanel/ea-libzip/lib64 -lzip'

    Hello, I also can confirm the problem, that sysvsem is shown as disabled in phpinfo.php and I don't find a way to enable it. The problem occoures under php81 fpm. Regards Thorsten

    Could one of you please submit a ticket on this? I'm not able to reproduce this on a test system, so we'd need to see it in action.

    In an account with PHP 8.1, in phpinfo, Configure Command, I see '--enable-sysvsem=shared' ', but if I turn PHP-FPM ON for that account I see '--disable-sysvsem'

    Indeed, turned off PHP-FPM for my NextCloud-hosting account and checked phpinfo() and also found "sysvsem" is now "shared".

    Sorry, should've checked to include it in my previous post: turned off FPM on all accounts, including cPanel daemons on the Service manager panel. phpinfo() shows "shared" for the NextCloud-hosting account. But NextCloud's Adminsitration Overview page still shows `sysvsem` as missing!?

    It's time to submit a ticket for this one since we've been chipping away at it for a few weeks. Can you create a ticket and then post the number here so I can follow along?

    I'd be prepared to do that, but I'm guessing you'd like access to my server. I'm currently focused on my CentOS-to-AlmaLinux migration. (Alas, scripted update not an option for VPS.) Maybe in a week or two if all goes well ... or, perhaps, someone else is in a position to help before then?

    Thanks for that - I'm following along with that ticket now.

    The solution is that, under PHP-FPM, the php81-php-process
    extension needs to be enabled.
