Check/adapt cron_worker_openerp for OpenERP 7

[Georges Racinet]

Just got this warning message (on a bzr trunk buildout)

anybox.recipe.openerp.server: Cron launcher openerp-cron-worker not found in openerp source tree (version 7.0alpha). This is expected with some nightly builds. Using the launcher script distributed with the recipe.

If OpenERP has changed theirs, chances that the one we distribute for OpenERP 6.1 does not work either

That must be checked before release of the recipe, hence the high importance.

[Georges Racinet (gracinet)]

At this point, cron-worker-openerp and the changes that support it have not been merged in OpenERP's trunk. They only got merged in 6.1 branch are revisions 4126 (6.1-here-comes-the-bogeyman) and 4184 (trunk-gunicorn-signaling).

Will reproduce that manually and query OpenERP maintainers about that.

[Georges Racinet (gracinet)]

The current OpenERP standard is to use --workers, but it has its own disadvantages, in some workflows.
We could well provide an "openerp_script" to lauch cron workers only, not bind on any network ports and have them preload the wish databases.

Nevertheless, this has not been critical for a good while.

[Georges Racinet (gracinet)]

A separate executable with no port bindings, using the main conf file option to take its number of workers, and optional preloading would complement nicely the OpenERP offering
