Slow building chromeos-chrome

Sometimes building chromeos-chrome was very slow (>30 mins). Downloading the browser from the build server should be fast. Right? It was a clean build. My client did not have any cros-workon. cros_sdk was started without any option. Any idea?

build_packages --board=daisy

Pending 9/10, Building 1/1, [Time 37m18.2s Load 0.14 0.18 0.38]

Still building chromeos-chrome-28.0.1498.0_rc-r1 (38m2.2s). Logs in /tmp/chromeos-chrome-28.0.1498.0_rc-r1-xes4GI

The log only has one line:

>>> Emerging (1 of 1) chromeos-base/chromeos-chrome-28.0.1498.0_rc-r1 from chromiumos for /build/daisy/

vnstat -l

I tried again and this time the log had lots of stuff (attached). My CHROME_ORIGIN value was SERVER_SOURCE. I thought the browser should have been directly downloaded from the build server. No?

chromeos-chrome-28.0.1498.0_rc-r1-yehFVj

Ryan knows best. But as far as I know, chromeos-chrome package does not use pre-built packages. SERVER_SOURCE means get a chrome checkout from server. It would be slower than LOCAL_SOURCE as checking out the chrome source tree takes quite sometime.

it depends on the board and manifest whether prebuilts are available. other times, a rebuild might get triggered due to a library changing.

Yup, looks like you're building from source here. Changing the USE flags you build

with can also invalidate prebuilts. Something you can try is doing a 'repo sync -d' to

reset your checkout to latest TOT, and doing cros_sdk --replace to re-create your

chroot. From there, a ./setup_board ./build_packages should start pulling Chrome

from pre-builts rather than trying to build from source.

Actually, seems like prebuilts for daisy and amd64-generic were broken

over the weekend. davidjames fixed it yesterday, so things should be

working now.

Thanks,

Ryan
