# Contributing
|
|
|
|
## Getting Started
|
|
|
|
Perkeep contributors regularly use Linux and OS X, and both are
|
|
100% supported.
|
|
|
|
Developing on Windows is sometimes broken, but should work. Let us
|
|
know if we broke something, or we accidentally depend on some
|
|
Unix-specific build tool somewhere.
|
|
|
|
See https://perkeep.org/doc/contributing for information on how to
|
|
contribute to the project and submit patches. Notably, we use Gerrit
|
|
for code review. Our Gerrit instance is at https://perkeep.org/r/
|
|
|
|
See architecture docs: https://perkeep.org/doc/
|
|
|
|
You can view docs for Perkeep packages with local godoc, or
|
|
godoc.org.
|
|
|
|
It's recommended you use git to fetch the source code, rather than
|
|
hack from a Perkeep release's zip file:
|
|
|
|
$ git clone https://camlistore.googlesource.com/camlistore perkeep
|
|
|
|
(We use github for distribution but its code review system is not as
|
|
nice as Gerrit, so we don't use its Pull Request mechanism. The Gerrit
|
|
git server & code review system is the main repo. See
|
|
https://perkeep.org/doc/contributing for how to use them. We might
|
|
support github for pull requests in the future, once it's properly
|
|
integrated with external code review tools. We had a meeting with
|
|
Github to discuss the ways in which their code review tools are poor.)
|
|
|
|
On Debian/Ubuntu, some deps to get started:
|
|
|
|
$ sudo apt-get install libsqlite3-dev sqlite3 pkg-config git
|
|
|
|
During development, rather than use the main binaries ("camput",
|
|
"camget", "camtool", "pk-mount", etc) directly, we instead use a
|
|
wrapper (devcam) that automatically configure the environment to use
|
|
the test server & test environment.
|
|
|
|
## Building devcam
|
|
|
|
To build devcam:
|
|
|
|
$ go run make.go
|
|
|
|
And devcam will be in <camroot>/bin/devcam. You'll probably want to
|
|
symlink it into your $PATH.
|
|
|
|
Alternatively, if your Perkeep root is checked out at
|
|
$GOPATH/src/perkeep.org (optional, but natural for Go users), you
|
|
can just:
|
|
|
|
$ go install ./dev/devcam
|
|
|
|
## Running devcam
|
|
|
|
The subcommands of devcam start the server or run camput/camget/etc:
|
|
|
|
$ devcam server # main server
|
|
$ devcam put # camput
|
|
$ devcam get # camget
|
|
$ devcam tool # camtool
|
|
$ devcam mount # pk-mount
|
|
|
|
Once the dev server is running,
|
|
|
|
- Upload a file:
|
|
|
|
devcam put file ~/perkeep/COPYING
|
|
|
|
- Create a permanode:
|
|
|
|
devcam put permanode
|
|
|
|
- Use the UI: http://localhost:3179/ui/
|
|
|
|
|
|
## Testing Patches
|
|
|
|
Before submitting a patch, you should check that all the tests pass with:
|
|
|
|
$ devcam test
|
|
|
|
You can use your usual git workflow to commit your changes, but for each
|
|
change to be reviewed you should merge your commits into one before submitting
|
|
to gerrit for review.
|
|
|
|
## Commit Messages
|
|
|
|
You should also try to write a meaningful commit message, which at least states
|
|
in the first sentence what part or package of perkeep this commit is affecting.
|
|
The following text should state what problem the change is addressing, and how.
|
|
Finally, you should refer to the github issue(s) the commit is addressing, if any,
|
|
and with the appropriate keyword if the commit is fixing the issue. (See
|
|
https://help.github.com/articles/closing-issues-via-commit-messages/).
|
|
|
|
For example:
|
|
|
|
> pkg/search: add "file" predicate to search by file name
|
|
>
|
|
> File names were already indexed but there was no way to query the index for a file
|
|
> by its name. The "file" predicate can now be used in search expressions (e.g. in the
|
|
> search box of the web user interface) to achieve that.
|
|
>
|
|
> Fixes #10987

|
## Vendored Code
|
|
|
|
Changes to vendored third party code must be done using the dep tool.
|
|
Information on adding, removing and updating vendor deps can be found
|
|
in the [dep documentation](https://github.com/golang/dep/blob/master/README.md).
|
|
|
|
Once you have your changes and versions specified please run the
|
|
following commands to update the vendor directory with your changes:
|
|
|
|
$ dep ensure
|
|
$ dep prune
|
|
|
|
To help track version changes please add the semantic version and the
|
|
revision in your commit message the version which you can find in the
|
|
Gopkg.lock file.
|
|
|
|
## Contributors
|
|
|
|
We follow the Go convention for commits (messages) about new Contributors.
|
|
See https://golang.org/doc/contribute.html#copyright , and examples such as
|
|
https://perkeep.org/gw/85bf99a7, and https://perkeep.org/gw/8f9af410.
|
|
|
|
## git Hooks
|
|
|
|
You can optionally use our pre-commit hook so that your code gets gofmt'ed
|
|
before being submitted (which should be done anyway).
|
|
|
|
$ devcam hook
|
|
|
|
Finally, submit your code to gerrit with:
|
|
|
|
$ devcam review
|
|
|
|
Please update this file as appropriate.
