README.md

WebTry Server

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

One time setup:

$ export SKIA_ROOT=path_to_your_skia_source
$ export WEBTRY_INOUT=path_to_a_writeable_directory
$ mkdir -p $WEBTRY_INOUT

Then, to run:

$ cd experimental/webtry
$ go get -d
$ ./build
$ ./webtry

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

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

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

Make sure port 80 is accessible externally for the above instance.

SSH into the instance:

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

Do the first time

The following things only need to be done once.

  1. SSH into the server as default.

  2. sudo apt-get install git

  3. git clone https://skia.googlesource.com/skia

  4. cd ~/skia/experimental/webtry/setup

  5. ./webtry_setup.sh

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

none /run/shm tmpfs rw,nosuid,nodev,noexec 0 0 /home/webtry/inout /skia_build/inout none rw,bind 0 0 /home/webtry/cache /skia_build/cache none rw,bind 0 0

  1. 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.

  1. Set the TCP keepalive. For more info see: https://developers.google.com/cloud-sql/docs/gce-access

    sudo sh -c 'echo 60 > /proc/sys/net/ipv4/tcp_keepalive_time'

To update the code

  1. SSH into the server as default.
  2. cd ~/skia/experimental/webtry/setup
  3. git pull
  4. ./webtry_setup.sh
