-Design
-======
-
-
-Overview
---------
-Allows trying out Skia code in the browser.
-
-
-Security
---------
-
-We're putting a C++ compiler on the web, and promising to run the results of
-user submitted code, so security is a large concern. Security is handled in a
-layered approach, using a combination of seccomp-bpf, chroot jail and rlimits.
-
-*seccomp-bpf* - Used to limit the types of system calls that the user code can
-make. Any attempts to make a system call that isn't allowed causes the
-application to terminate immediately.
-
-*chroot jail* - The code is run in a chroot jail, making the rest of the
-operating system files unreachable from the running code.
-
-*rlimits* - Used to limit the resources the running code can get access to,
-for example runtime is limited to 5s of CPU.
-
-User submitted code is also restricted in the following ways:
- * Limited to 10K of code total.
- * No preprocessor use is allowed (no lines can begin with #includes).
-
-
-Architecture
-------------
-
-The server runs on GCE, and consists of a Go Web Server that calls out to the
-c++ compiler and executes code in a chroot jail. See the diagram below:
-
- +–––––––––––––+
- | |
- | Browser |
- | |
- +––––––+––––––+

- | | | |||
- | | +––––––––––+||
- | +––––––––––––––+|

- +––––––––––––––––––+
-
-The user code is expanded into a simple template and linked against libskia
-and a couple other .o files that contain main() and the code that sets up the
-seccomp and rlimit restrictions. This code also sets up the SkCanvas that is
-handed to the user code. Any code the user submits is restricted to running in
-a single function that looks like this:
-
-
- void draw(SkCanvas* canvas) {
- // User code goes here.
- }
-
-The user code is tracked by taking an MD5 hash of the code The template is
-expanded out into <hash>.cpp, which is compiled into <hash>.o, which is then
-linked together with all the other libs and object files to create an
-executable named <hash>. That executable is copied into a directory
-/home/webtry/inout, that is accessible to both the web server and the schroot
-jail. The application is then run in the schroot jail, writing its response,
-<hash>.png, out into the same directory, /home/webtry/inout/, where is it read
-by the web server and returned to the user.
-
-Startup and config
-------------------
-The server is started and stopped via:
-
- sudo /etc/init.d/webtry [start|stop|restart]
-
-But sysv init only handles starting and stopping a program once, so we use
-Monit to monitor the application and restart it if it crashes. The config
-is in:
-
- /etc/monit/conf.d/webtry
-
-The chroot jail is implemented using schroot, its configuration
-file is found in:
-
- /etc/schroot/chroot.d/webtry
-
-The seccomp configuration is in main.cpp and only allows the following system
-calls:
-
- exit_group
- exit
- fstat
- read
- write
- close
- mmap
- munmap
- brk
-
-Database
---------
-
-Code submitted is stored in an SQL database so that it can be referenced
-later, i.e. we can let users bookmark their SkFiddles.
-
-The storage layer will be Cloud SQL (a cloud version of MySQL). Back of the
-envelope estimates of traffic come out to a price of a about $1/month.
-
-All passwords for MySQL are stored in valentine.
-
-To connect to the database from the skia-webtry-b server:
-
- $ mysql --host=173.194.83.52 --user=root --password
-
-Initial setup of the database, the user, and the tables:
-
- CREATE DATABASE webtry;
- USE webtry;
- CREATE USER 'webtry'@'%' IDENTIFIED BY '<password is in valentine>';
- GRANT SELECT, INSERT, UPDATE ON webtry.webtry TO 'webtry'@'%';
- GRANT SELECT, INSERT, UPDATE ON webtry.workspace TO 'webtry'@'%';
- GRANT SELECT, INSERT, UPDATE ON webtry.workspacetry TO 'webtry'@'%';
- GRANT SELECT, INSERT, UPDATE ON webtry.source_images TO 'webtry'@'%';
-
- // If this gets changed also update the sqlite create statement in webtry.go.
-
- CREATE TABLE webtry (
- code TEXT DEFAULT '' NOT NULL,
- create_ts TIMESTAMP DEFAULT CURRENT_TIMESTAMP NOT NULL,
- hash CHAR(64) DEFAULT '' NOT NULL,
- width INTEGER DEFAULT 256 NOT NULL,
- height INTEGER DEFAULT 256 NOT NULL,
- source_image_id INTEGER DEFAULT 0 NOT NULL,
- PRIMARY KEY(hash),
-
- FOREIGN KEY (source) REFERENCES sources(id)
- );
-
- CREATE TABLE workspace (
- name CHAR(64) DEFAULT '' NOT NULL,
- create_ts TIMESTAMP DEFAULT CURRENT_TIMESTAMP NOT NULL,
- PRIMARY KEY(name),
- );
-
- CREATE TABLE workspacetry (
- name CHAR(64) DEFAULT '' NOT NULL,
- create_ts TIMESTAMP DEFAULT CURRENT_TIMESTAMP NOT NULL,
- hash CHAR(64) DEFAULT '' NOT NULL,
- width INTEGER DEFAULT 256 NOT NULL,
- height INTEGER DEFAULT 256 NOT NULL,
- source_image_id INTEGER DEFAULT 0 NOT NULL,
- hidden INTEGER DEFAULT 0 NOT NULL,
-
- FOREIGN KEY (name) REFERENCES workspace(name),
- );
-
- CREATE TABLE source_images (
- id INTEGER PRIMARY KEY NOT NULL AUTO_INCREMENT,
- image MEDIUMBLOB DEFAULT '' NOT NULL, -- Stored as PNG.
- width INTEGER DEFAULT 0 NOT NULL,
- height INTEGER DEFAULT 0 NOT NULL,
- create_ts TIMESTAMP DEFAULT CURRENT_TIMESTAMP NOT NULL,
- hidden INTEGER DEFAULT 0 NOT NULL
- );
-
- ALTER TABLE webtry ADD COLUMN source_image_id INTEGER DEFAULT 0 NOT NULL AFTER hash;
- ALTER TABLE workspacetry ADD COLUMN source_image_id INTEGER DEFAULT 0 NOT NULL AFTER hash;
-
-Common queries webtry.go will use:
-
- INSERT INTO webtry (code, hash) VALUES('int i = 0;...', 'abcdef...');
-
- SELECT code, create_ts, hash FROM webtry WHERE hash='abcdef...';
-
- SELECT code, create_ts, hash FROM webtry ORDER BY create_ts DESC LIMIT 2;
-
- // To change the password for the webtry sql client:
- SET PASSWORD for 'webtry'@'%' = PASSWORD('<password is in valentine>');
-
- // Run before and after to confirm the password changed:
- SELECT Host, User, Password FROM mysql.user;
-
-Common queries for workspaces:
-
- SELECT hash, create_ts FROM workspace ORDER BY create_ts DESC;
-
- INSERT INTO workspace (name, hash) VALUES('autumn-river-12354', 'abcdef...');
-
- SELECT name FROM workspace GROUP BY name;
-
-Common queries for sources:
-
- SELECT id, image, width, height, create_ts FROM source_images ORDER BY create_ts DESC LIMIT 100;
-
-Password for the database will be stored in the metadata instance, if the
-metadata server can't be found, i.e. running locally, then a local sqlite
-database will be used. To see the current password stored in metadata and the
-fingerprint:
-
- gcutil --project=google.com:skia-buildbots getinstance skia-webtry-b
-
-To set the mysql password that webtry is to use:
-
- gcutil --project=google.com:skia-buildbots setinstancemetadata skia-webtry-b --metadata=password:'[mysql client webtry password]' --fingerprint=[some fingerprint]
-
-To retrieve the password from the running instance just GET the right URL from
-the metadata server:
-
- curl "http://metadata/computeMetadata/v1/instance/attributes/password" -H "X-Google-Metadata-Request: True"
-
-N.B. If you need to change the MySQL password that webtry uses, you must change
-it both in MySQL and the value stored in the metadata server.
-
-Source Images
--------------
-
-For every try the user can select an optional source image to use as an input.
-The id of the source image is just an integer and is stored in the database
-along with the other try information, such as the code.
-
-The actual image itself is also stored in a separate table, 'sources', in the
-database. On startup we check that all the images are available in 'inout',
-and write out the images if not. Since they are all written to 'inout' we can
-use the same /i/ image handler to serve them.
-
-When a user uploads an image it is decoded and converted to PNG and stored
-as a binary blob in the database.
-
-The bitmap is available to user code as a module level variable:
-
- SkBitmap source;
-
-The bitmap is read, decoded and stored in source before the seccomp jail is
-instantiated.
-
-
-Squid
------
-
-Squid is configured to run on port 80 and run as an accelerator for the actual
-Go program which is running on port 8000. The config for the squid proxy is
-held in setup/sys/webtry_squid, which is copied into place during installation
-and squid is kept running via monit.
-
-Workspaces
-----------
-
-Workspaces are implemented by the workspace and workspacetry tables. The
-workspace table keeps the unique list of all workspaces. The workspacetry table
-keeps track of all the tries that have occured in a workspace. Right now the
-hidden column of workspacetry is not used, it's for future functionality.
-
-Code Editor
------------
-[CodeMirror](http://codemirror.net/) is used for rich code editing. The
-following files are included from the official CodeMirror distribution and can
-be updated in place (no local customizations):
-
- * codemirror.js - base CM implementation
- * codemirror.css - base CM stylesheet
- * clike.js - C-like syntax highlighting support
-
-Alternatively, we may consider pulling CM as an external dependency at some
-point.
-
-Installation
-------------
-See the README file.

-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.
-
-
-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
-
-7. 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.
-
-8. 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
-
-
-Third Party Code
-================
-
- * res/js/polyfill.js - Various JS polyfill libraries. To rebuild or update
- see poly/README.md.

-polyfill.js
-===========
-
-To rebuild or update res/js/polyfill.js you will need to have
-[node.js](http://nodejs.org/) installed. Once you have it installed run the
-following (assuming you are in experimental/webtry directory):
-
-$ cd poly
-$ npm install
-$ grunt
-
-If you want to create a verion of the polyfill.js that hasn't been minified,
-say for debugging purposes, then run:
-
-$ cd poly
-$ npm install
-$ grunt notmin
