commit-bot@chromium.org 4f3452d62e Flesh out the list of includes, also fix up README markdown Currently only pulls in 'core' and 'effects'. Will add in gpu once we add an option to render via Mesa.

README.md

WebTry

Allows trying out Skia code in the browser. Run a local webserver and from the pages it serves try out Skia code and see the results immediately. To make sandboxing easier this must be built w/GPU off.

Running Locally

$ GYP_GENERATORS=ninja ./gyp_skia gyp/webtry.gyp gyp/most.gyp -Dskia_gpu=0 $ ninja -C out/Debug webtry $ cd experimental/webtry $ go build webtry.go $ ./webtry

Then visit http://localhost:8000 in your browser.

Only tested under linux, doubtful it will work on other platforms.

Full Server Setup

Create a GCE instance:

gcutil --project=google.com:skia-buildbots addinstance skia-webtry-b
--zone=us-central2-b --external_ip_address=108.170.220.126
--service_account=default
--service_account_scopes="https://www.googleapis.com/auth/devstorage.full_control"
--network=default --machine_type=n1-standard-1 --image=backports-debian-7-wheezy-v20140331
--persistent_boot_disk

SSH into the instance:

gcutil --project=google.com:skia-buildbots ssh --ssh_user=default skia-webtry-b

The following things only need to be done once

sudo apt-get install git schroot debootstrap
git clone https://skia.googlesource.com/skia
Add the following to /etc/fstab and reboot:

none /dev/shm tmpfs rw,nosuid,nodev,noexec 0 0

The above will allow ninja to run. See http://stackoverflow.com/questions/2009278/python-multiprocessing-permission-denied

Add the following to the /etc/schroot/minimal/fstab:

/home/webtry/inout /inout none rw,bind 0 0

Change /etc/monit/monitrc to:

set daemon 2

then run the following so it applies:

sudo /etc/init.d/monit restart

This means that monit will poll every two seconds that our application is up and running.

Do the following the first time you setup a machine, and each time you want to update the code running on the server

cd ~/skia/experimental/webtry/setup ./webtry_setup.sh

Do these steps only once, but only after running webtry_setup.sh the first time

sudo debootstrap --variant=minbase wheezy /srv/chroot/webtry
