[xRes] PHP73
by Soeren Pestner 26 May '23

26 May '23

Good Morning. The day has come. Today I will merge my PHP73 branch into develop. What we have to do. development ----------- There is a short time we have to develop for PHP72 (bugfixes release/23.07) and PHP73 (release/23.08). E.g. I have two xRes checkouts that I run in different docker containers, so I can easily switch. In the most cases you haven't to do that, but as soon you have to run composer you need the right PHP environment. bamboo build plans ------------------ All bamboo build plans start with pre configured PHP72 runtime environment. I will change this to PHP73 right after my merge. That's the best way but not optimal at all, because all new created builds without these changes are PHP72 and will fail. You have to adjust it manually. I hope that will happen not too often. Contact me, if you run in any strange build errors. system adjustments ------------------ Some test system are already running with PHP73 and it will be more during release/23.08 testing week. Our live systems stay at PHP72 until all customers get the new version and we can be sure that there will not be a bigger problem. Until that we will run a PHP73 software on PHP72 Systems, that mostly shouldn't be a problem. known problems -------------- Some composer sub dependencies are not configured via composer.json and only be pinned by the current PHP version. An update to PHP73 could lead to an update of those packages and could cause errors. There are many changes in PHPunit framework. In the current branch everything works fine but some well known things were changed. Bamboo build plans use a shared composer cache and in some cases parallel PHP73 and PHP72 builds can fail. Contact me if you won't have a clue what's going on. The oldest supported PHP versions is 8.0 until end of this year. We are very late. ;) Good luck. -- -- Sören Pestner - Entwickler - TraSo GmbH Nonnenstraße 42 D-04229 Leipzig telefon: +49 341 909 87 49 email: s.pestner(a)traso.de Geschäftsführer: Haiko Gerdes Handelsregister: Amtsgericht Leipzig (HRB 21850)

PHP GlusterFS write performance
by Gunnar Mann 07 Dec '20

07 Dec '20

Dear all, we experienced a severe performance impact in a php application writing small data chunks to our GlusterFS network file system. Some details can be found here <https://aimeos.org/tips/modern-php-applications-up-to-110x-slower-on-networ…> and there <https://serverfault.com/questions/86000/can-you-explain-why-i-shouldnt-serv…> - the baseline is that file_exists, is_dir and all functions using system call lstat can not be cached in APC and cause GlusterFS to check with the quorum of servers during the operation. Python and native linux applications ( C ) do not have this problem, so there is no obvious need to fix at system side. The problem did not arise on xRes data importing where only single big writes are placed on GlusterFS. Testing around with php realpath_cache_size and opcache settings did not help. Jacob implemented a simple memory buffering for collecting file writes into bigger chunks which turned out to be the single most helpful workaround. Furthermore it helps to not use file_put_contents inside big loops but open and close files only once outside a loop. See examples: Best: buffering and fopen()/fclose() called only once, 0.8 sec: $line = str_repeat('x', 128) . PHP_EOL; $buffer = ''; $fh = fopen('/data/php_test.txt', 'w+'); for ($i = 0; $i < 100000; $i++) { $buffer .= $line; if ($i % 1000 === 0) { fwrite($fh, $buffer); $buffer = ''; } } fwrite($fh, $buffer); fclose($fh); 2.5 times slower: buffering and open/write/close inside loop, 2.0 sec: $line = str_repeat('x', 128) . PHP_EOL; $buffer = ''; for ($i = 0; $i < 100000; $i++) { $buffer .= $line; if ($i % 1000 === 0) { file_put_contents('/data/php_test.txt', $buffer, FILE_APPEND); $buffer = ''; } } file_put_contents('/data/php_test.txt', $buffer, FILE_APPEND); Worst: unbuffered plain open/write/close inside loop: 186 sec $line = str_repeat('x', 128) . PHP_EOL; for ($i = 0; $i < 100000; $i++) { file_put_contents('/data/php_test.txt', $line, FILE_APPEND); } Having fopen(), fclose() outside of loops may help writing to hard disks, too. Any more ideas? -- Mit freundlichen Grüßen Gunnar Mann - Systemadministration - ________________________________________________________ TraSo GmbH Nonnenstraße 42 D-04229 Leipzig Tel.: +49 341 355 740 76 Fax: +49 341 355 740 21 E-Mail: g.mann(a)traso.de <mailto:g.mann@traso.de> <https://www.traso.de/> <https://www.facebook.com/TraSoGmbH> <https://www.xing.com/companies/trasogmbh> ________________________________________________________ Geschäftsführer: Haiko Gerdes Handelsregister: Amtsgericht Leipzig, HRB 21850 <https://www.kununu.com/de/traso1> ________________________________________________________ Geschäftsführer: Haiko Gerdes Handelsregister: Amtsgericht Leipzig, HRB 21850 <https://www.kununu.com/de/traso1>

xMid web0x SHM-Fix
by Felix Seidel 06 Oct '20

06 Oct '20

We have again problems with our shared-memory area in xmid. It looks like php is not able to defend multiple write actions to the same mem-area at the same time. We are working on a solution, but until then you can "reset" the shm-part of apache by: 1. ssh into reported xmid web-server 2. sudo ipcs -m | grep apache will return something like: 0x41400290 1 apache 666 20480 0 0x41400068 4 apache 666 20480 0 for every row: 3. ipcrm -M "shm-block" root(a)web01.app /dev/shm # ipcrm -M 0x41400290 root(a)web01.app /dev/shm # ipcrm -M 0x41400068 4. success! Afterwards accounting should work until next crash (: See you, Felix -- Mit freundlichen Grüßen Felix Seidel - Lead Developer xMid - ________________________________________________________ TraSo GmbH Nonnenstraße 42 D-04229 Leipzig Tel: +49 341 355 740 47 E-Mail: f.seidel(a)traso.de Internet: https://www.traso.de ________________________________________________________ Geschäftsführer: Haiko Gerdes Handelsregister: Amtsgericht Leipzig, HRB 21850

Temp file handling docker containers

Dear Devs, please note that in current and coming docker setups for our applications, we reserve around 10GB for *all* docker operating systems. For example all 4 new docker xRes db01 systems together occupy 1.3 - 1.4GB for different oss and 700GB for databases. => count on nothing more than a few hundred MB in „/tmp" or "/var/tmp“ directories and plan to put all production data in production data volumes which are configured at docker deployment - we’ll help you here Kind regards Gunnar -- Mit freundlichen Grüßen Gunnar Mann - Systemadministration - ________________________________________________________ TraSo GmbH Nonnenstraße 42 D-04229 Leipzig Tel.: +49 341 355 740 76 Fax: +49 341 355 740 21 E-Mail: g.mann(a)traso.de <mailto:g.mann@traso.de> <https://www.traso.de/> <https://www.facebook.com/TraSoGmbH> <https://www.xing.com/companies/trasogmbh> ________________________________________________________ Geschäftsführer: Haiko Gerdes Handelsregister: Amtsgericht Leipzig, HRB 21850 <https://www.kununu.com/de/traso1> ________________________________________________________ Geschäftsführer: Haiko Gerdes Handelsregister: Amtsgericht Leipzig, HRB 21850 <https://www.kununu.com/de/traso1>
