  • Eric Vaughan and Stuart Parmenter got scrolling to blit on Linux, although a few problems with this need to be fixed before it can be checked in. (pavlov, evaughan)
  • David Hyatt co-hosted a XUL/RDF chat, with Chris Waterson and Robert Churchill, on MozillaZine. (hyatt)
  • Resolved 53 bugs in the last week, fixing 18 of them.  See our resolved bug list  for details.
  • We haven't had enough volunteer typists to capture the output from David Hyatt's fertile brain.  He's actually been reduced to processing the output of a cable-driven electron gun, delivering DOM-less content known only as "WB" to a phosphor-coated screen.  Please, if you have anything that Dave can help with, that does not involve typing, let us know.  A mind is a terrible thing to waste...
  1. Daniel Matejka fixed nsIEventQueue to not lose NSPR events when modal windows go away. The corresponding leak remains -- for now. (danm)
  2. Daniel also got James Toder's Windows window title patch checked in and credited. (danm)
  3.  Steve Dagley verified more NSPR 3.5 changes (now that NSPR 3.5 has been moved to the Mozilla tree the NSPR group is more sensitive to XP changes affecting the Mac so he pre-tests the landings) (sdagley)
  4. Steve also fielded some Communicator 4.7 and Mac OS 9 compatability firedrill investigation and PR.  Some part of 4.7 accessed some forbidden low-memory globals, which causes an exception on OS9. (sdagley)
  5. Eric and Pav also figured out a way to remove native widgets. (evaughan, pavlov)
  6. Eric also fixed tab view to hide widgets instead of compressing them.  (evaughan)
  7. Eric worked on cleaning up some xpapps dialogs too.  (evaughan)
  8. Pav also got Unix packaging code up-to-date so .xpi files can be built on Unix. (pavlov)
  9. David Hyatt has been working on 'brutal' sharing of content. (hyatt)
  10. Dave also reviewed the new UI for next week's landing.  (hyatt)
  11. Chris Saari got DOM level focus events and user level focus interaction much improved on Mac, ie. pretty close to 4.x.  Working on adding the user level stuff to Windows and then Linux before committing. (saari)
Current work
  1. Danm: 15856, 16551.
  2.  Pavlov:
     *16552 - general unix painting bugs
     * 2564  - scrolling large docs on linux does bad drawing things
  3. Evaughan: Linux scrolling, native widget removal.
  4. Saari: Windows & Linux focus work.
  5. SDagley: 16202 (to be landed tomorrow and nsIFile implemenation for the Mac (bug # unknown)
  6. Hyatt: brutal sharing.
  1. Finish Windows & Linux focus work and checkin this weekend. (saari)
  2. Kill some XPMenu bugs and manage my bug list. (saari)
  3. Fast scrolling on Linux. (pavlov, evaughan)
  4. Get rid of native widgets. (evaughan, pavlov)
  5. Clean up dialogs. (evaughan)
  6. Fix typing problems. (pavlov)
  7. Brutal sharing. (hyatt).

  • 41 editor bugs were resolved this past week
  • 28 open M11 bugs, 7 are PDT+
  • Steve made significant improvements in text control performance
  • Akkana worked on IME issues most of the week
  • Kin checked in the makefile so spell check will work on Linux
  • Charley is making significant progress with the Editor UI
  • Simon continues to help improve performance and startup issues
  • Kathy is plowing through the key event issues
  • Team has completed their goals and objectives for the year.


  • Team has 213 total open bug count. Steve and Joe are the most doomed at this point.
  • Didn't get a status from Mike or Joe


  • Steve:
    • Working on major text control performance improvements for bug 14727. A 300 text control page now loads in about 2 seconds, rather than over 1 minute in optimized M10 build. The webshell redesign will help with the performance (space) problem even further, so there's less penalty per focus'd control. We can now consider the space/time tradeoff of having just a single webshell (soon to be "docshell") per page.
    • Nearing final design for the webshell. Hope to have design finalized Monday, and do a review with jar, hamerly, rickg, kipp, troy, rickp, hyatt on Tuesday.  Result of review will be to either go with our design, or find a way of scaling back our design to meet time+risk factors.
  • Akkana
    • Fixed 16706 -- a blocker in InsertHTML for mail quoting and signatures.
    • Fixed 15463 (which in turn fixed 16542, 16670, 16645, 16844, 16795) needed to fix the Unix XIM code and re-enable it.
    • She also fixed: 16998 (IM blocker, hiding the illegal attribute on our new <br type="_moz"> tag), 16726 (tracking a change in doctype handling in the parser), 16441 (entity conversion), 16285 (crash in the copy code on Windows), 15777(a gcc compilation problem)
  • Kin
    • Began work on bug 16176 need to annotate line frames with whitespace trim
    • Spent some time looking at selection redraw problems that happen on Linux when scrolling.
    • Checked in top level makefile changes to build spellchecker on Linux by default.
    • Working with mjudge on selection issues

Pavlov got blit-based scrolling to work, but native widgets used for iframes, select inputs, text fields and toolboxes are still a problem. Native widgets in input control are planned to switch to GFX.

Evaughan: working on a demonstration with no native widgets, to see how fast this can be. Disadvantage: applets can have window show through.

GFX Scroll bars: still not on by default because of glacial Linux scrolling, an editor crash double-clicking on URL bar (mistaken assumption that frame tree is isomorphic to DOM tree) assigned to Buster, and missing arrows on Mac/Linux. Need someone to run Quantify on Solaris to find real delays on Linux. Evaughan to look into speeding things up by remove widget from webshell, if that is easy.

Need nsiFile work for architectural completeness/correctness. DougT already loaded with SSL & Webshell work. Travis is talking more about incremental changes to webshell, rather than a wholesale rewrite all at once. This work will still take more horsepower, RPotts is likely candidate to help out.

Vidur: Content notification going well, table bugs getting resolved. Tables now rearranging themselves as more content comes in. Some bugs, Vidur is fixing them and hopes to land tomorrow. In the meantime, he is going through the top 100 sites, will get a big review tomorrow from Kipp & Troy. Speed is quite good on Linux (thanks Pav!), not quite as good on Win32. Brendan will call Troy to see if he has cycles to help out.

Waterson: Brutal sharing: should be done in 2 weeks, with bulk of the performance gain (content model sharing) in by middle of next week.


Presentation went well, Ref count balancer went over very well, pizza went over even better.

SmFr has a graph of load time plotted against library size, by component. Talked with Nisheeth about splitting up layout dll, since it is way out on both scales. Also has a list of all dlls loaded, so you can see if any are being loaded that shouldn't be. No obvious big candidates to be split off to load after startup, some incremental things like data sources split from RDF.

May be possible to combine some libraries (e.g., XUL into Layout) to get a speedup. Some things being loaded that could be delayed (OJI, Wallet, Plugin, Cookies). Need finer-grained analysis using Quantify, to find out, on a method basis, what is actually being called at startup, when, and how much space the remainder takes. May be able to group them based on locality of temporal reference, or pipeline the loading. Could also combine some with the app so they load all at once. Some components take much longer to load than their size would indicate (widgets), why? Appshell, Widget et. al. also still include native widgets used only by Viewer, we should split them out to avoid loading them in Apprunner. Forms code includes duplicate code to deal with native and GFX widgets, but shipping product will not need any native widget support. Other components have some duplicate code too.

Need to find out why Layout is so large, is there any way to reduce it or slice it up to load faster at startup? May be able to reduce size of binaries by 25-30% on Mac by building with exceptions turned on, using new tools which may not be ready for prime time quite yet. VC5 tools produce consistently more compact binaries than VC6, why? Apple sped things up by combining, then stripping dead code. Could we do something like that? Could stick everything in one project, measure what got stripped, just to get the data.

Shaver is working on adding editing to Titledbuttons, using some XUL popups.

Schedule: Need to get to architectural completeness, APIs ready (Mozilla alpha?), before getting an interesting feature set (Moz beta). API review process will run into next year, but they should be 75% done by alpha.

The 3rd edition of the ECMA-262 specification for JavaScript is nearly ready to go. This edition standardizes aspects of JavaScript that the previous editions missed, including exceptions, try/catch blocks and regular expressions. Check it out at (PDF format)

News from Roger Lawrence:

Resolved 14060, 6704, 12951, 15593, 15197. Other sundry bugs in Rhino, Monkey. Working on proper ECMA handling for all undefined or NULL args to functions. Changing test suite to match ECMA 3 specification. (previous versions is tagged)

Next week - more of the same, plus JS1.5 delta doc stuff.

SPARC build failures still unresolved.

Lots of news from John Bandhauer:

  • I continued fixing little leaks and one corruption bug in xpconnect.
  • I implemented nsIXPCNativeCallContext as a system for native code called from JS to get at underlying JS args etc.
  • I fixed nsIXPCSecurityManager filtering problems in xpconnect to deal with problems that norris is running into.
  • I spent some time thinking about JS debugging in mozilla issues so that I can point the UWO team in the right direction and help where appropriate.
  • I'm looking for help in ownership of issues and code regarding xptcall on 'nix platforms. Issues regarding binary incompatibility of xpcom components built with various compiler flags and libraries are starting to surface again. Here is a posting I did about the issues some time back... Besides the coordination of 'nix efforts issues, I'd love to find a qualified owner for the (functional but suboptimal) Linux version of xptcall.
  • I started design work on xpconnect refactoring needed to fix a number of bugs on my list. This requires a lot of juggling. I will try to sort it all out into a presentable form and get some design review.
  • bugs (all relying on xpconnect refactoring): 13419 13429 13425 13418
