Engineering Status

  • waterson
    • Helped dbaron wrap up 45676  (scrollbar hover leak). This was a hard, hard leak, and dbaron deserves most of the credit.
    • Worked up fixes for the following bugs:
      • 44480 div not resizing to window; we were using width of <html> element, not <body>
      • 47154 entities cause whitespace to disappear; turns out that \n and \r not treated as whitespace
      • 48086 lose selection after sort; regression caused by fix to 46616
    • Conference call with IBM bidirection text layout group. Their changes went onto a branch this week to prepare for "touch down" (i.e., under #ifdef) early next week.
  • vidur
    • Spent most of the week working with Johnny Stenback on DOM string  changes. We're changing the nsString&'s in the DOM API to nsAReadableString& and nsAWritableString& to get rid of problems with fragility and allow us to use different string implementations where appropriate. The changes touch a large number of files and should land sometime this week.
    • API Review for the embedding interfaces. We're done with our first round of reviewing! Judson's group is going to make the IDL changes and send them out for first review very soon.
    • Footprint/Performance management meeting.
    • Held a meeting on remoting XPCOM. Jband is looking into this as part of a web application story.
  • rayw
    • Lots of communications with developers requiring or affected by XPCOM changes WRT nsbeta3, resulting in a more-complete picture.
    • Better triaging for XPCOM.
    • More progress on the changes to APIs and progids.
    • Posted text regarding progid -> capability changes.
    • Expect early next week to recieve finished target APIs and progids, which I have worked on up until now.
    • Another issue was the plugin and string bundle registrations in the component registry.  I feel that perhaps we can just use a new registry and leave these things to others to clean up -- they can actually remove the oldregistry when it is clean.  We don't have to push them into it.
  • waldemar
    • Worked on JavaScript 2.0 language definition and on tools to allow me to maintain separate specs for ECMAScript Edition 4 and JavaScript 2.0 while using a common document base.
    • Investigated several Mozilla CSS1 bugs.
    • Arranged short ECMAScript Edition 4 meeting with Microsoft on August 22nd.
  • rpotts
    • should return from vacation next week
  • jband
    • Trying to focus on footprint and performance bugs. So far these include: 48855, 46707, 46703, 43902. I expect that more digging will reveal other good places where I can help make improvements.
    • Also did some work on JavaScript and XPConnect bugs: 48564, 47354, 39808.
  • warren
    • Landed changes for hashtable string keys. Saved 1M of space to startup and load the handful of tinderbox test pages.
    • Still trying to get jar packaging up and running. Unfortunately, things have bit-rotted considerably since I had it working on Windows and Linux last week -- trying to debug what's going wrong now.
  • dprice
    • on vacation until 8/14
  • scc
    • made a lot of progress on multi-fragment strings
    • fixed up BeginReading, et al, routines to be efficient for multi-fragment strings
    • wrote the underlying chunk-list management for multi-fragment strings; more to follow
    • got multi-fragment strings limping along; they pass all tests except those related to Substring and nsPromiseConcatenation
    • figured out how to make substrings and concatenations work for everybody (and improvements to iterator), but haven't implemented yet
    • supported vidur and jst's effort to convert the DOM APIs
      • rewrote NS_NewAtom to work with readables, though I'm not sure how vidur and jst want to get these changes
      • bug #48464: fixed nsAWritable[C]String assignment problems
      • wrote a character sink based on nsCRT::HashValue to support adapting NS_NewAtom for nsAReadableStrings as part of Vidurs DOM conversion work
    • fixed bugs
    • reviewed, tested, and/or checked-in other peoples patches
    • wrote documentation
      • added more examples of using iterators to modify strings in place, and thoughts on copy_string drawn from an email discussion
      • wrote and emailed the comparison of Opera and Mozilla, which I needed to do for
      • attended meetings
      • staff meeting (1 hour)
      • API review meeting (1.5 hours)

August 18
Submitted by Dan Mosedale <>


  • Added a debugging frob allowing users to specify various NS_ASSERTION behavior by an environment variable, including dumping a stack trace to stderr or suspending the process so a debugger can be attached. See for details on how it works.


  • With help from the new debugging frob and Doug Turner, tracked down threadsafety assertion when callbacks happen on the LDAP connection thread.
  • Major fixes to the code that cleans up at the end of an LDAP search and/or when a search has been cancelled. Most visible effect: the throbber should always stop spinning at the end of a search, rather than sometimes lingering on indefinitely. Thanks to Judson Valeski for helping me sort this stuff out.
  • Helped Mike Shaver test fixes to the Javascript component loader so that the capability permissions on function callbacks are lexically closed, not just variable scopes. This unblocks the RDF datasource, so I'm now back to work on that.
