= Gerrit Code Review - Developer Setup
|
|
|
|
Facebook Buck is needed to compile the code, and an SQL database to
|
|
house the review metadata. H2 is recommended for development
|
|
databases, as it requires no external server process.
|
|
|
|
|
|
== Getting the Source
|
|
|
|
Create a new client workspace:
|
|
|
|
----
|
|
git clone --recursive https://gerrit.googlesource.com/gerrit
|
|
cd gerrit
|
|
----
|
|
|
|
The `--recursive` option is needed on `git clone` to ensure that
|
|
the core plugins, which are included as git submodules, are also
|
|
cloned.
|
|
|
|
|
|
== Compiling
|
|
|
|
For details on how to build the source code with Buck, refer to:
|
|
link:dev-buck.html#build[Building on the command line with Buck].
|
|
|
|
|
|
== Switching between branches
|
|
|
|
When switching between branches with `git checkout`, be aware that
|
|
submodule revisions are not altered. This may result in the wrong
|
|
plugin revisions being present, unneeded plugins being present, or
|
|
expected plugins being missing.
|
|
|
|
After switching branches, make sure the submodules are at the correct
|
|
revisions for the new branch with the commands:
|
|
|
|
----
|
|
git submodule update
|
|
git clean -fdx
|
|
----
|
|
|
|
|
|
== Configuring Eclipse
|
|
|
|
To use the Eclipse IDE for development, please see
|
|
link:dev-eclipse.html[Eclipse Setup].
|
|
|
|
For details on how to configure the Eclipse workspace with Buck,
|
|
refer to: link:dev-buck.html#eclipse[Eclipse integration with Buck].
|
|
|
|
|
|
== Configuring IntelliJ IDEA
|
|
|
|
To use IntelliJ IDEA for development, the easiest way is to follow
|
|
Eclipse integration and then open it as Eclipse project in IDEA.
|
|
You need the Eclipse plugin activated in IntelliJ IDEA.
|
|
|
|
|
|
== Mac OS X
|
|
|
|
On Mac OS X ensure "Java For Mac OS X 10.5 Update 4" (or later) has
|
|
been installed, and that `JAVA_HOME` is set to the
|
|
link:install.html#Requirements[required Java version].
|
|
|
|
Java installations can typically be found in
|
|
"/System/Library/Frameworks/JavaVM.framework/Versions".
|
|
|
|
You can check the installed Java version by running `java -version` in
|
|
the terminal.
|
|
|
|
[[init]]
|
|
== Site Initialization
|
|
|
|
After compiling (above), run Gerrit's 'init' command to create a
|
|
testing site for development use:
|
|
|
|
----
|
|
java -jar buck-out/gen/gerrit.war init -d ../gerrit_testsite
|
|
----
|
|
|
|
Accept defaults by pressing Enter until 'init' completes, or add
|
|
the '--batch' command line option to avoid them entirely. It is
|
|
recommended to change the listen addresses from '*' to 'localhost' to
|
|
prevent outside connections from contacting the development instance.
|
|
|
|
The daemon will automatically start in the background and a web
|
|
browser will launch to the start page, enabling login via OpenID.
|
|
|
|
Shutdown the daemon after registering the administrator account
|
|
through the web interface:
|
|
|
|
----
|
|
../gerrit_testsite/bin/gerrit.sh stop
|
|
----
|
|
|
|
|
|
== Testing
|
|
|
|
|
|
[[tests]]
|
|
=== Running the Acceptance Tests
|
|
|
|
Gerrit has a set of integration tests that test the Gerrit daemon via
|
|
REST, SSH and the git protocol.
|
|
|
|
A new review site is created for each test and the Gerrit daemon is
|
|
started on that site. When the test has finished the Gerrit daemon is
|
|
shutdown.
|
|
|
|
For instructions on running the integration tests with Buck,
|
|
please refer to:
|
|
link:dev-buck.html#tests[Running integration tests with Buck].
|
|
|
|
|
|
=== Running the Daemon
|
|
|
|
The daemon can be directly launched from the build area, without
|
|
copying to the test site:
|
|
|
|
----
|
|
java -jar buck-out/gen/gerrit.war daemon -d ../gerrit_testsite
|
|
----
|
|
|
|
=== Running the Daemon with Gerrit Inspector
|
|
|
|
link:dev-inspector.html[Gerrit Inspector] is an interactive scriptable
|
|
environment to inspect and modify internal state of the system.
|
|
|
|
This environment is available on the system console after
|
|
the system starts. Leaving the Inspector will shutdown the Gerrit
|
|
instance.
|
|
|
|
The environment allows interactive work as well as running of
|
|
Python scripts for troubleshooting.
|
|
|
|
Gerrit Inspect can be started by adding '-s' option to the
|
|
command used to launch the daemon:
|
|
|
|
----
|
|
java -jar buck-out/gen/gerrit.war daemon -d ../gerrit_testsite -s
|
|
----
|
|
|
|
Gerrit Inspector examines Java libraries first, then loads
|
|
its initialization scripts and then starts a command line
|
|
prompt on the console:
|
|
|
|
----
|
|
Welcome to the Gerrit Inspector
|
|
Enter help() to see the above again, EOF to quit and stop Gerrit
|
|
Jython 2.5.2 (Release_2_5_2:7206, Mar 2 2011, 23:12:06)
|
|
[OpenJDK 64-Bit Server VM (Sun Microsystems Inc.)] on java1.6.0 running for Gerrit 2.3-rc0-163-g01967ef
|
|
>>>
|
|
----
|
|
|
|
With the Inspector enabled Gerrit can be used normally and all
|
|
interfaces (HTTP, SSH etc.) are available.
|
|
|
|
Care must be taken not to modify internal state of the system
|
|
when using the Inspector.
|
|
|
|
=== Querying the Database
|
|
|
|
The embedded H2 database can be queried and updated from the
|
|
command line. If the daemon is not currently running:
|
|
|
|
----
|
|
java -jar buck-out/gen/gerrit.war gsql -d ../gerrit_testsite
|
|
----
|
|
|
|
Or, if it is running and the database is in use, connect over SSH
|
|
using an administrator user account:
|
|
|
|
----
|
|
ssh -p 29418 user@localhost gerrit gsql
|
|
----
|
|
|
|
|
|
[[debug-javascript]]
|
|
=== Debugging JavaScript
|
|
|
|
When debugging browser specific issues add `?dbg=1` to the URL so the
|
|
resulting JavaScript more closely matches the Java sources. The debug
|
|
pages use the GWT pretty format, where function and variable names
|
|
match the Java sources.
|
|
|
|
----
|
|
http://localhost:8080/?dbg=1
|
|
----
|
|
|
|
|
|
== Client-Server RPC
|
|
|
|
The client-server RPC implementation is gwtjsonrpc, not the stock RPC
|
|
system that comes with GWT. This buys us automatic XSRF protection.
|
|
It also makes all of the messages readable and writable by any JSON
|
|
implementation, facilitating "mashups" and 3rd party clients.
|
|
|
|
The programming API is virtually identical, except service interfaces
|
|
extend RemoteJsonService instead of RemoteService.
|
|
|
|
|
|
== Why GWT?
|
|
|
|
We like it. Plus we can write Java code once and run it both in
|
|
the browser and on the server side.
