I have checked in the code for [Bug 76070] we need namespace support from the DOM. This code gives the transformiix DOM namespace IDs and atoms for localnames. This will give us some great tools for both performance and correctness and was one of our major architecture blockers. Thanks to Jonas Sicking for starting this and both him and peterv for great input after I took over this bug. Kudos for sr go to jst.

  • We have too many bugs on our 0.9.6 list, needs triaging. jst is doomed with his untriaged list (over 100) and would need some help.
  • heikki will be on vacation 10/26.

  • Good progress on Message Compose performance and Folder Loading made this week.
  • A number of top crashers fixed this week.
  • Resolved as fixed 26 bugzilla bugs.

Performance and Footprint

  • Seth started working on 104989.  This would improve the performance of opening a compose window on the next window after a send.  We'll hide the most recently used compose window and then reuse it on the next compose operation.  Results look promising so far.  If this works out we'll look into the costs of making it behave this way for the first compose window.
  • Cavin and David worked on folder loading performance.  They have an improvement for UpdateFolder() which looks to have some promising results.  The overall improvement appears to range from 4%-8% based on 1000 and 4000 message folders, where the larger folders see the larger improvement.  The improvement to UpdateFolder() itself ranges from 17%-30% based on the size of the folder.  The improvement involved a reduction in the number of times we call memset and memcpy.

Mailnews Accomplishments

  • Cavin
    • Made it so that when removing an account from the Account Settings dialog, the current panel doesn't stay on the deleted account.
    • Worked on performance changes for UpdateFolder() which will speed up folder loading.
  • Navin
    • Completed Quick Search.  The review is under way.
    • Made the pop3 message downloading limit size pref work again.
    • Fixed a bug where there was no error when creating a duplicate local folder through the filter ui.
    • Created an initial design doc for the manual execution of filters.
  • Scott
    • Fixed an imap top crasher.
    • Created XBL widgets for the message headers.
    • The new XBL widgets were used to do View All Headers.
  • Sean
    • Started work on the Labels feature.   He worked on getting the new column to show up and started working on the preference panel.
  • David
    • Fixed a crash that occurred while emptying the trash folder.
    • Fixed a crash when you tried to rename a local folder while it's being reparsed.
    • Fixed a MIME crash.
    • Fixed a problem which caused a bunch of assertions when searching newsgroups if you hadn't opened the newsgroup.
    • Worked with Cavin on the folder loading optimizations mentioned above.
  • Jean-Francois
    • He started rewriting the way we store attachment information in the message compose window.  This will let us store more information about the content-type and the attachment name.  We have a number of bugs where we don't show a good name for the attachment or where garbage shows up in the attachment pane in international builds.  This should allow us to fix these.  
  • Varada
    • Prefill Filters is going through review.
    • Started working on Block Addresses.
  • Bhuvan
    • Investigated using the new Wizard for the Account Wizard.  Converting to this will solve a lot of the accessibility problems we have with the current Wizard.
  • Seth
    • Started working on the compose window performance improvement mentioned above.
    • Bulletproofed a topcrash in outliner.
    • Created a default height for the thread pane, thereby preventing an extra paint on startup.
    • Started working on landing Address Book Search.
