In Episode 15, we kept working on the same bug as the last two episodes – proxying the printing dialog on OS X to the parent process from the content process. At the end of Episode 14, we’d finished the serialization bits, and put in the infrastructure for deserialization. In this episode, we did the rest of the deserialization work.
And then we attempted to print a test page. And it worked!
We did it!
Then, we cleaned up the patches and posted them up for review. I had a lot of questions about my Objective-C++ stuff, specifically with regards to memory management (it seems as if some things in Objective-C++ are memory managed, and it’s not immediately obvious what that applies to). So I’ve requested review, and I hope to hear back from someone more experienced soon!
I also plugged a new show that’s starting up! If you’re a designer, and want to see how a designer at Mozilla does their work, you’ll love The Design Hour, by Ricardo Vazquez. His design chops are formidable, and he shows you exactly how he operates. It’s great!
Finally, I failed to mention that I’m on holiday next week, so I can’t stream live. I have, however, pre-recorded a shorter Episode 16, which should air at the right time slot next week. The show must go on!
In this episode, I kept working on the same bug as last week – proxying the print dialog from the content process on OS X. We actually finished the serialization bit, and started doing deserialization!
Hopefully, next episode we can polish off the deserialization and we’l be done. Fingers crossed!
Note that this episode was about 2 hours and 10 minutes, but the standard-definition recording up on Air Mozilla only plays for about 13 minutes and 5 seconds. Not too sure what’s going on there – we’ve filed a bug with the people who’ve encoded it. Hopefully, we’ll have the full episode up for standard-definition soon.
Had to deal with some network issues during this video – sorry if people were getting dropped frames during the live show! I have personally checked this recording, and almost all frames are there.
The only frames that are missing are the ones where I scramble around to connect to the wired network, which was boring anyhow.
In this episode, I worked on proxying the print dialog from the content process on OS X. It was a wild ride, and I learned quite a bit about Cocoa stuff. It was also a throwback to my very first episode, where I essentially did the same thing for Linux!
We’ll probably polish this off in the next episode, or in the episode after.
Luckily, the last bug we were working on was related to this – we had a lot of context about cache keys swapped in already.
The other important thing to realize is that fixing this bug is a bandage fix, or a wallpaper fix. I don’t think those are official terms, but it’s what I use. Basically, we’re fixing a thing with the minimum required effort because something else is going to fix it properly down the line. So we just need to do what we can to get the feature to limp along until such time as the proper fix lands.
My proposed solution was to serialize an nsISHEntry on the content process side, deserialize it on the parent side, and pass it off to nsIWebBrowserPersist.
So did it work? Watch the episode and find out!
I also want to briefly apologize for some construction noise during the video – I think it occurs somewhere halfway through minute 20 of the video. It doesn’t last long, I promise!
