Updating pdf.js on Mozilla Central

Initial Setup (hopefully one time)

• Get Commit Access Level 1 (http://www.mozilla.org/hacking/committer/) (https://bugzilla.mozilla.org/show_bug.cgi?id=714712)
• Check out Mozilla Central (https://developer.mozilla.org/En/Simple_Firefox_build)
• Setup HG
  • Edit ~/.hgrc (https://developer.mozilla.org/en/Mercurial_FAQ#How_can_I_generate_a_patch_for_somebody_else_to_check-in_for_me.3f) Mine:

[ui]
username = YOUR NAME <[email protected]>

[defaults]
qnew = -Ue

[extensions]
hgext.mq =

[diff]
git = 1
showfunc = 1
unified = 8

[paths]
try = ssh://hg.mozilla.org/try

• Edit ~.ssh/config

Host hg.mozilla.org
        User [email protected]
        IdentityFile ~/.ssh/id_rsa

• Setup Git
  • Make sure your account's default identity is set.

git config --global user.email "[email protected]"
git config --global user.name "Your Name"

+ On Windows, make sure automatic line endings conversion is turned off.

git config --global core.autocrlf false

Updating Steps

• make sure all patches are popped off your queue

hg qpop -a

• update moz central

hg pull -u

• update pdf.js and build extension

gulp mozcentral

• (or, if you know previous commit sha for built pdf.js you can generate build/mozcentral.diff file)

BASELINE=<baseLineCommit> gulp mozcentralbaseline; gulp mozcentraldiff

• Open new bugzilla bug

  • Copy release notes there
  • Set depends bug ????

• Create Patch (replace bug number)

hg qnew bug-743264-fix -m "Bug 743264 - Update pdf.js to Version 0.2.537."

• Update Files

# copy files build ./build/mozcenral/* into mozilla-central/ root
hg qrefresh

• Add Try Stuff

hg qnew try --message "try: -b do -p macosx,macosx64,win32,linux,linux32 -u all -t none"

• Double Check What Your Sending

hg outgoing

• Push to Try Server

hg push -f try

• Pop off the try patch (if you can't pop the patch see https://wiki.mozilla.org/ReleaseEngineering/TryServer#Disable_hg_phases_with_a_post-push_hook )

hg qpop

• Generate Patch (after successful try run, replace bug number)

hg export qtip > ~/projects/mine/pdf.js/patches~/bug-743264-fix.patch

If Uplift is Needed

• Find what version of pdf.js is in the branch by looking at the pdf.js file and PDFJS.build variable e.g. PDFJS.build = 'f8e70dc';

• Check out that version

git checkout -b tt-aurora-fix <baseLineCommit>

• Cherry Pick the commit you need to uplift

git cherry-pick <someCommit>

• Build the patch

BASELINE=<baseLineCommit> gulp mozcentralbaseline; gulp mozcentraldiff

• Apply that to the branch

qimport -n cherry-pick <pdf.js build folder>/mozcentral.diff; qpush;
