Build and update your own B2G build daily-ish without blow away data. Now comes with localization testing.

B2G Personal daily dogfooding instruction

This is how I generate my dogfood build, daily-ish. I do so to ensure I have (almost) total control over what goes into my phone so I could pick up the changes anytime I wanted (and indentifying the version of Gaia/Gecko I am using).

This instruction is used for Geeksphone Peak and with zh-TW locale. Replace/remove instruction for your own phone.

File locations:

• update.sh should go to $B2G (the place you clone B2G repo with git).
• local.mk contains specific instructions for Gaia, put it in $B2G/gaia.
• languages_mine.json should go to $B2G/gaia/locales.

languages_mine.json

{
  "en-US"     : "English (US)",
  "zh-TW"     : "正體中文 (繁體)"
}

local.mk

# For 1.5dppx Peak -- switch visual assets to 1.5dppx ones.
GAIA_DEV_PIXELS_PER_PX=1.5

# Use official branding (do not distribute your resulting build without written permission from Mozilla)
PRODUCTION=1
MOZILLA_OFFICIAL=1

# This sets DevTools access to allowed in mozSettings

# Select your favorite keyboard layouts/IME
# Here are some of the layouts/IME of my special interests.

# Include your favorite locales
# Your locales should be listed in the languages_mine.json file. Copy the labels from languages_all.json.

update.sh

# Update your locale repo first
# Note that you'll need to manually clone the locale repo to B2G/gaia/locales directory from one of the repo in
# https://hg.mozilla.org/gaia-l10n/ first, like
# hg clone https://hg.mozilla.org/gaia-l10n/zh-TW/ B2G/gaia/locales/zh-TW
hg -R gaia/locales/zh-TW pull -u default

# Before bug 922463 is fixed, we will need to reset the local changes made by multilocale script before we sync
# Warning: this reset all the uncommitted changes in the repo too!
# git --git-dir=./gaia/.git --work-tree=./gaia/ checkout .

# Update and config B2G itself and start building
# Build a "user" build so that Gaia will be put in the system partation
git pull &&\
BRANCH=master TARGET_BUILD_VARIANT=user ./config.sh peak &&\
./build.sh TARGET_BUILD_VARIANT=user ||\
exit

# Pause
read

# Flash *only* the system partation to NOT removing data.
# Mind that you might want to remove data when you flash the phone for the first time.
./flash.sh system

the line # "hg clone https://hg.mozilla.org/gaia-l10n/zh-TW/ B2G/gaia/locales/zh-TW" could be
# hg clone https://hg.mozilla.org/gaia-l10n/zh-TW/ gaia/locales/zh-TW

so people can uncomment and use it directly at first time

@gasolin, fixed, thanks.
