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.
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.
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
The following things only need to be done once.
SSH into the server as default.
sudo apt-get install git
git clone https://skia.googlesource.com/skia
cd ~/skia/experimental/webtry/setup
./webtry_setup.sh
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
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.
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'
