git checkout -b new_branch from inside other branch

Note to self, when you do git checkout -b new_branch on an old_branch, you are continuing form that old_branch.
So better to start from master, unless you really know what you are doing.

Some git commands

To see all availabe branches (similar to available mercurial queues): git branch
To make a new branch: git branch branch_name
To go to a specific branch: git checkout branch_name

To add changes to a github pull request:
git add . (git add --all also removes entries when there are removed files)
git commit -m "your commit message"
git push branch_name

To see changed files between master and your branch:
git diff --name-status master..branch_name

To remove file from git: git rm file_name

How to prevent pushing changes to master (at least without warning):
git config push.default nothing


update master

git fetch upstream
git merge upstream/master

Git regarding forking a repo


adb shell
stop b2g
cd /data/b2g/mozilla/*.default/

PAC file = Proxy auto-config file

.bashrc edit on the emulator to find ssltunnel

Because of bug 1002545 :
You need to build your own Firefox desktop build to get an ssltunnel version
That's why you need to edit .bashrc on the b2g emulator:

Mtbf = mean time between failures


Working b2g emulator

To get working b2g emulator:
- Use Ubuntu14 VMWare image, 60GB storage, 4GB memory
- Follow
 - Build mozilla-central firefox also on it (see bug 1002545):
# hg clone
# cd mozilla-central
# ./mach bootstrap
# ./mach build
# export XULRUNNER_DIRECTORY=$PWD/obj-x86_64-unknown-linux-gnu/dist
Then go to B2G folder and run ./mach mochitest-remote 


Loop Client testing

Between FirefoxOS Phone (Flame) and Firefox Nightly desktop

  1. In terminal: git clone
  2. Follow instructions at:
  3. Add the packaged app firefoxos-loop-client
  4. Make a call on the firefoxos-loop client
  5. Open Firefox Nightly on desktop, open the url that was shared with the firefoxos-loop-client app url.


Turning Windows Search off also can help.

In the spec, there a four main objects involved in a document load and

3) Window (aka. inner window)
4) Document

Each browsing context has a WindowProxy. Each Document has a Window.

Is that last bit true for documents returned via XMLHttpRequest, say?

An nsDocShell corresponds exactly to a browsing context, right?


Does an nsIContentViewer correspond exactly to the spec's (inner) Window for the
purpose of the loading machinery even though the JS object corresponding
to Window is an nsGlobalWindow marked as being of the inner flavor?

An nsIContentViewer corresponds in lifetime to a document, sort of (some documents have no associated content viewer, and documents in general can outlive their content viewer if someone just holds on to them, but for purposes of loading machinery the correspondence is correct I think).

In the spec, a Window has a 1-to-1 correspondence to a Document except
when the Window's document changes from the initial about:blank into
another Document. Does the same hold for nsIContentViewer?


Does it also get coupled 1-to-1 to an nsIDocument except for the initial about:blank?

No. The initial about:blank and the document that actually loads have different content viewers.

Have I understood correctly that an nsIContentViewer is always also an
nsIDocumentViewer and always an DocumentViewerImpl?

Yes, in our implementation. Modulo binary extensions, of course.

(What's the point of
having separate nsIContentViewer and nsIDocumentViewer interfaces?)

I believe at one point (before my time, I think) there was a plan to have non-document viewers (e.g. for full-page images, full-page plugins, whatever). I don't believe there is such a plan anymore. Certainly not on my part!
