sympa.pl: Add an option "--rebuildarc=list@domain" to rebuild archives

[ldidry]

Relative to #993: with this option, we can rebuild all archives with a simple for bash loop, without restarting from beginning if archived.pl restarts while rebuilding all lists.

The keyword rebuild_arc has never been used. I feel rebuildarc looks less confusing.

[ldidry]

I have no pb with that. I choosed rebuild_arc since it’s closer to natural language.

[racke]

Natural language would be rebuild_archives. An arc is part of a building.

[ldidry]

I said "closer", not "exactly" 😅

[ldidry]

Now, it’s rebuildarc.

It's a quick and useful utility. I see absolutely nor problem with it.
Actually, I wonder whether the "rebuild all" command should be declined in a similar way : a set of single "rebuild list" tasks for each list.

(in the doc, I would say "rebuild the list's archives" but then again it's perfectly understandable this way)

It may be more simple than track the state of "rebuild all lists" task.

While it’s doable, it could take a lot of time to create all the "rebuild list" messages if there is many lists, so it would make a timeout on the web interface. I suggest, if this is a thing we want to do, to create a "schedule rebuild all list" message that would create all the "rebuild list" messages when processed.

What do you think?

[dverdin]

Yes, that's certainly the best approach.
This way, the request is instantaneous.
However, it's way out of the current PR's scope. It's perfect this way.

[ikedas]

I found no problem.

Merged for now. Please check the next beta in tomorrow.
