Making Xcode faster
* If you use SourceTree, command line Git, etc:
* Preferences > Source Control > uncheck Enable Source Control.
* This will also stop Xcode from screwing up your `git rebase` calls by taking the lock file!
* Hide the sidebars.
* Disable live issues.
* Preferences > General > Show live issues.
* Turn off compiler warnings for subprojects (e.g., deprecation warnings for Breakpad).
* Sidebar: click "Breakpad.xcodeproj". Build Settings > search for "Deprecated Functions", set the middle two columns to "No".

Bookmark Sync 2

Implementing bookmarks sync… again

Since our first installment we've implemented batched downloading for bookmarks: Bug 1201108.

This incrementally populates a local snapshot of the server (initially termed the ‘mirror’, now more accurately renamed the ‘buffer’), validating each record and fitting the contents into a relational schema. As it processes folders it also fills a table with the top-down structure of the downloaded records. We can be confident that when the downloader finishes, we'll have everything the server currently contains, minus any records that aren't well-formed.

What's next?

We're not done with schema changes: Bug 1201110. The buffer is a blind and forgetful one: it truly represents the current state of the server. We need more than that to sync — in order to find out what changed on each end since we last synced we n

Bookmark Sync 1

Designing bookmark sync… again

For the second time, I'm building an implementation of bookmark sync on a new platform. The last one, in early 2012, was Firefox for Android. That turned out relatively well, considering the circumstances, but it didn't go far enough in avoiding some ancient errors baked into the desktop codebase.

For Firefox on iOS we have a new set of platform constraints and a strong desire to avoid some of the known pitfalls. This post sets out some of the considerations. A future post will set out the proposed solution.

Our goal: keep a tree of bookmarks in sync across multiple devices.

Syncs occur to and from a server. Devices don't communicate directly.

19:51 <@rnewman> any desktop client that applies that record is gonna have a bad time.
