how to increase php memory limit for drush without access to php.ini

I recently found myself trying to use drush to set up a Drupal 6 install on a server where I did not have root access. I kept getting errors along the lines of this:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 1234 bytes)

I didn't have permission to edit the php.ini file for php_cli, so I had to find another workaround. The solution's pretty simple and comes courtesy of the drushrc.php file.

drush looks in a list of locations for a config file, and the example.drush.php which you'll find inside includes in your drush directory contains the following instructions:

 * Rename this file to drushrc.php and optionally copy it to one of
 * five convenient places, listed below in order of precedence:
 *
 * 1. Drupal site folder (e.g sites/{default|example.com}/drushrc.php).
 * 2. Drupal installation root.
 * 3. In any location, as specified by the --config (-c) option.
 * 4. User's .drush folder (i.e. ~/.drush/drushrc.php).
 * 5. System wide configuration folder (e.g. /etc/drush/drushrc.php).
 * 6. Drush installation folder.

I simply followed these instructions (going for ~/.drush/drushrc.php in this case), and added the following line to the end of the file:

ini_set('memory_limit',          '128M');

You can check that this is getting picked up like so:

drush php-eval 'print ini_get("memory_limit")' ;
128M

...and the real proof of the pudding is that I'm no longer getting the memory exhausted error messages.

Works drush 5.0 dev

thanks worked great with Drush 5.0 dev version (pair.com)

php.ini

Also, you can drop a override php.ini in ~.drush/ or /etc/drush/ according to the block starting in line 67 in http://drupalcode.org/project/drush.git/blob/d06335d8354ad0624fa7d0efbb3...

Thanks!

Works a charm, thank you
