Taskwarrior: Tasks spontaneously duplicate themselves

[ulope]

• What command(s) did you run?

Unknown, possibly related to syncing with inthe.am

• What did you expect to happen?

Tasks not to be duplicated

• What actually happened?

All not done tasks are duplicated. This is the second time this happened since I started using taskwarrior in May.

• Paste the output of the task diag command.

It has happened again. I start to suspect that repeating tasks are somehow involved. I purposefully haven't synced for the last 5 days or so.

Yesterday (the 30th) everything was fine, today (the 1st) I again am seeing 19 dupes.

[ddeimeke]

Did you set recurrence=0 on all but one Taskwarrior clients?

From the manpage:

       recurrence=1
              Controls  whether recurrence is enabled, and whether recurring tasks con‐
              tinue to generate new task instances. Defaults to "1".

              If you are syncing multiple clients, then it  is  advised  that  you  set
              'recurrence=1'  on  your  primary client, and 'recurrence=0' on ALL other
              clients. This is a workaround for a duplication bug.

[Aerex]

@ddeimeke Can we assume that the primary client is the first client synced with the server?

[JavaZauber]

Shouldn't this logic be server-side?

[arooni]

also affected on mac after making some edits for my monthly/weekly goals.. seems to echo issue above.

recurrence = 0 on all clients but one. and issue is not with recurring tasks but just regular tasks.

[arooni]

anyway to remove duplicates automatically? task diagnostics seems to find them but can it remove them?

right now i'm having to copy from my ubuntu machine where the duplicates seem not to have occurred and scp'ing the files back to my mac. kinda frustrating.

[meonkeys]

Here's the duplication bug mentioned in the manpage: https://github.com/GothenburgBitFactory/taskserver/issues/46

[devurandom]

Is this a duplicate of #1649 (which potentially has duplicates in #1962, #1963)?

[pbeckingham]

Closing as a duplicate.
