These changes, 295.33 KiB of them for a -U 3 patch, comprise a removal of 2,732 lines of code for 1,871 lines in a total of 52 files, some of which are OS-specific, and the culmination of over 6 months of editing and revising, a timespan also including a change of computers. I've changed the internals of nsAbCardProperty at least three times, and fixed two bugs in a heretofore unused mork class. The APIs I worked off of have changed several times, partially as a result of my experiences with the work, and partially otherwise. Finally, I have my chance to bitrot other people's WIPs instead of finding that any addressbook change bitrots the patch I have (or another in my queue).
The good news: nsIAbCard is now effectively stable to use in extensions or other core code not yet pushed. The only caveats are these:
- getProperty* has had some late-breaking API discussions, related to how to handle properties that don't exist. It is possible, but not likely, that semantics of existing methods would be changed.
- copy is not the best thought-out method and will change in the future.
- equals has some potential problems, such as the fact that its use in circumstances may violate the reflexive property.
- UUIDs were stripped from the patch pending future design decisions.
- The two pre-existing properties will exist only as long as mailing lists are insane.
Will this patch create regressions? Probably one or two minor ones; changing an entire internal model, a heavily-used API, and implementations across several files, some of which are OS-specific, and others which are app-specific makes a regression likely. But I have taken effort to find problems, combing through the little import/export I can test with Linux, as well as using all the features I could. grep has proved invaluable, as well as a few tests of Dehydra to find callees.
What's next from here? The next logical step is the creation of nsIAbCollection and related refactoring. However, async APIs and error conditions are still in flux for that. Not all of the OS-specific directories are fully squared away with the new model, but I have limited testability in those areas. UI unforking is a place where we could win big, especially as it saves me a few places to look for usages. Import and palmsync may also want some more love. Naturally, there are also the spin-off bugs, but many of those are not immediately fixable.
For me, at least, I now have some time to work on other bugs while I wait. There are 12 other bugs in my queue, ranging from an IMAP fakeserver to an aggravating news bug to a brand new module (O.K., total rewrite of an old module), 6 of which are more or less ready to be committed. Oh well, life goes on...
