| 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]. |
| |
| |
| 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]. |
| |
| |
| Mac OS X |
| -------- |
| |
| On Mac OS X ensure "Java For Mac OS X 10.5 Upate 4" (or later) has |
| been installed, and that `JAVA_HOME` is set to |
| "/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home". |
| Check the installed version by running `java -version` and looking |
| for 'build 1.6.0_13-b03-211'. Versions of Java 6 prior to this |
| version crash during the build due to a bug in the JIT compiler. |
| |
| |
| [[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 ../test_site |
| ---- |
| |
| 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: |
| |
| ---- |
| ../test_site/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 ../test_site |
| ---- |
| |
| |
| 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 ../test_site |
| ---- |
| |
| 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 |
| ---- |
| |
| To use the GWT DETAILED style the package must be recompiled and |
| `?dbg=1` must be omitted from the URL: |
| |
| ---- |
| mvn package -Dgwt.style=DETAILED |
| ---- |
| |
| |
| Release Builds |
| -------------- |
| |
| To create a release build for a production server, or deployment |
| through the download site: |
| |
| ---- |
| ./tools/release.sh |
| ---- |
| |
| If AsciiDoc isn't installed or is otherwise unavailable, the WAR |
| can still be built without the embedded documentation by passing |
| an additional flag: |
| |
| ---- |
| ./tools/release.sh --without-documentation |
| ---- |
| |
| |
| 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. |
