Today
- Next week is Episode 300!
- I'm going to see if I can contribute a fix to Thunderbird!
- I started as a contractor working on Thunderbird for a subsidiary of Mozilla called Mozilla Messaging
- MZLA Technologies now runs Thunderbird
- Failing that, in anticipation for the upcoming Monkey Island game, I thought we could examine the ScummVM implementation of the SCUMM engine!
- I'm going to see if I can contribute a fix to Thunderbird!
- No episodes on September 21st or September 28th due to travel
Let's review a patch!
Goal: I want the JumpListManager to only ever be accessed off of the main thread, so that the main thread in the parent process never has to await a lock.
- [x] Get rid of maxListItems, since it doesn't appear to be used
- [x] Get rid of isListCommitted
- [x] Make .available return a Promise
- [x] Make abortListBuild return a Promise
- [x] Make deleteActiveList return a Promise
- [ ] Make SetAppUserModelId return a Promise
- [ ] Make addListToBuild return a Promise
- [ ] Make commitListBuild return a Promise instead of using that old callback mechanism
- [ ] Update all of the callers of the above methods!
- [ ] Remove locks and monitors
- [ ] Migrate off of dedicated lazy thread to background thread pool
