Add `retry` parameter to http-ish storages

[ahemwe]

I use vdirsyncer with cron to backup caldav and carddav data from posteo.de

At one of two sync actions, I get at least one "connection refused" error.

error: Unknown error occured for my_calendar/jtmfam: HTTPSConnectionPool(host='posteo.de', port=8443): Max retries exceeded with url: /calendars/its.me/abc/ (Caused by NewConnectionError('<requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x71797070>: Failed to establish a new connection: [Errno 111] Connection refused',))
error: Use `-vdebug` to see the full traceback.
error: Unknown error occured for my_calendar/default: HTTPSConnectionPool(host='posteo.de', port=8443): Max retries exceeded with url: /calendars/its.me/default/ (Caused by NewConnectionError('<requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x717dbd10>: Failed to establish a new connection: [Errno 111] Connection refused',))
error: Use `-vdebug` to see the full traceback.
error: 2 out of 12 tasks failed.

Is there a possibility to allow more than one retry? Thanks a lot for this great tool!

Makes sense, though you really should look into what causes those connection drops.

Since I have the same problem, I'd be interested in this too. I'm guessing it is caused by rate limiting at the hoster.

Patches welcome :)

@ahemwe: May I ask for your config for Posteo? I haven't got mine to work.

Seeing several problems, among:

/.well-known/caldav was not found on this server.
Failed to discover collections
Unknown error occured: local variable 'discovered' referenced before assignment

@SinBirb You're wellcome :-)

I was getting back the same error during discover "/.well-known/caldav was not found on this server."

But when I change my password fetch command from

password.fetch =  ["command", "pass", "email/posteo"]

to

password.fetch = ["prompt", "Posteo password: "]

it started to work :o

[untitaker]

Hmmm ok, please open a new issue for this
