1095119 - Remove Promise.defer usage

Status: RESOLVED FIXED

(Calendar :: Internal Components, defect)

Description

[Philipp Kewisch [:Fallen] [:📆][:🧩]]

I totally liked Promise.defer, but this is not a feature of DOM promises, which will supersede Promise.jsm at some point and will be removed in bug 1034599. We need to replace them with DOM promises in calendar code or use PromiseUtils from bug 1093021.

Here, I realized that implementation of new Promise() as deferred object would require a helper function first and so it's better to look out for places where new Promise can be implemented easily and I found it was in only test_deleted_items.js, every where else our beloved deferred object is used to resolve promise in different parts of code,so I implemented new Promise() here. Would request a review and help in case I have done something wrong.

You are right, we surprisingly don't use promises that much. Code looks great, thanks for the patch! Let me know if you need more issues to work on. r=philipp.

For checkin, could you change the patch message from "Remove Promise.defer" to something like "Bug 1095119 - Remove Promise.defer usage. r=philipp", upload that as a new attachment and set the checkin-needed keyword? You can directly set review+ on the new patch since I've already +'d this one.

I think bug 472630 would be nice, if you want another simple one then bug 842383 is also a good candidate.

Attachment: fix test failure

The patch caused a failure in the test it is touching:
TEST-UNEXPECTED-FAIL | xpcshell-icaljs.ini:calendar/test/unit/test_deleted_items.js | xpcshell return code: 0
SyntaxError: expected expression, got ')' at /builds/slave/test/build/tests/xpcshell/tests/calendar/test/unit/test_deleted_items.js:31
ReferenceError: run_test is not defined at /builds/slave/test/build/tests/xpcshell/head.js:504

I try to fix the syntax error in this patch.

Aryx, please push to try server.

fix test failure v2

Oops I totally missed you already uploaded a patch, sorry about that. The patch I pushed does about the same thing and also fixes the order of setting the handleCompletion function and calling aFunc().
