Camlistore 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 http://camlistore.org/docs/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://camlistore.org/r/
See architecture docs: https://camlistore.org/docs/
You can view docs for Camlistore packages with local godoc, or
godoc.org.
It's recommended you use git to fetch the source code, rather than
hack from a Camlistore release's zip file:
$ git clone https://camlistore.googlesource.com/camlistore
(We use github for distribution but its code review system is so poor,
we don't use its Pull Request mechanism. The Gerrit git server & code
review system is the main repo. See
http://camlistore.org/docs/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", "cammount", etc) directly, we instead use a
wrapper (devcam) that automatically configure the environment to use
the test server & test environment.
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 Camlistore root is checked out at
$GOPATH/src/camlistore.org (optional, but natural for Go users), you
can just:
$ go install ./dev/devcam
The subcommands of devcam start the server or run camput/camget/etc:
$ devcam server # main server
$ devcam appengine # App Engine version of the server
$ devcam put # camput
$ devcam get # camget
$ devcam tool # camtool
$ devcam mount # cammount
Once the dev server is running,
- Upload a file:
devcam put file ~/camlistore/COPYING
- Create a permanode:
devcam put permanode
- Use the UI: http://localhost:3179/ui/
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.
You should also try to write a meaningful commit message, which at least states
in the first sentence what part of camlistore this commit is affecting. The
following text should state what problem the change is addressing, and how.
An example would be:
"
HACKING: add tips about writing a commit message.
First time committers are not always aware about good commit message etiquette.
These few notes should help them.
"
You can optionally use our pre-commit hook so that your code gets gofmt'ed
before being submitted (which should be done anyway).
$ cd .git/hooks
$ ln -s ../../misc/pre-commit.githook pre-commit
Finally, submit your code to gerrit with:
$ devcam review
