Support for trac 0.11

Reported by: ejucovy Owned by: ejucovy
Priority: normal Component: WorkflowNotificationPlugin
Severity: normal Keywords:
Cc: Trac Release: 0.11


When active in a Trac 0.11.7 environment, the plugin causes an error in the browser when submitting a new ticket or editing an existing ticket. The error only occurs if one or more notifications would be triggered by the current submission.

The error is:

Resolution: fixed
Status: newclosed

Fixed in 46576fe0 and tagged & released as 0.4

Trac's function trac.notification:NotifyEmail.notify changed its signature between 0.12 and 1.0; in 0.12 and earlier versions, it only took two arguments. The plugin now inspects that function's signature to figure out how many arguments to send it.

That's not a public API method in Trac -- the plugin just uses it because it's a reasonably convenient way to send out an email that respects ALWAYS_CC and ALWAYS_BCC and the other general purpose notification settings, but it's a bad hack. At some point it should be replaced with a more stable way to send an email.

I don't think it's effectively any different than what you did, but Trac actually has a util function even back in 0.11 for checking the number of arguments:.
