FS#2444 - composer hits memory limits

Quick anwser: enable swap partition on your server.

Tried upgrading a rc4-dev to rc5-dev/rc6/flyspray-master on a virtual server with 500MB RAM and php5.6.30 on the commandline (debian)

After file upgrade, I wanted also update the vendor stuff according to composer.json changes.

But surprisingly this failed:

php composer.phar update

and also after

php composer.phar selfupdate


to version Composer version 1.5.2 2017-09-11 the memory limit bug exists:

The following exception is caused by a lack of memory or swap, or not having swap configured
Check https://getcomposer.org/doc/articles/troubleshooting.md#proc-open-fork-failed-errors for details

PHP Warning:  proc_open(): fork failed - Cannot allocate memory in phar:///var/www/***/composer.phar/vendor/symfony/console/Application.php on line 979

Warning: proc_open(): fork failed - Cannot allocate memory in phar:///var/www/***/composer.phar/vendor/symfony/console/Application.php on line 979

  [ErrorException]
  proc_open(): fork failed - Cannot allocate memory

Also doing a more fresh vendor install like

rm composer.lock
rm vendor/*
(keeps the .htaccess there)
php composer.phar install

300 MB not enough for a handful of php package installations? wtf, but didn’t dig deeper..

I temporarly solved the problem by making a swap partition on this vServer like suggested at
https://getcomposer.org/doc/articles/troubleshooting.md#proc-open-fork-failed-errors

/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
/sbin/mkswap /var/swap.1
chmod 600 /var/swap.1
/sbin/swapon /var/swap.1
free

This is just documentation and is for the people who prefer a Flyspray development version from github.com

Full Flyspray release download files do not needs to fiddle with composer.
