# Contributing to rclone #
|
|
|
|
This is a short guide on how to contribute things to rclone.
|
|
|
|
## Reporting a bug ##
|
|
|
|
If you've just got a question or aren't sure if you've found a bug
|
|
then please use the [rclone forum](https://forum.rclone.org/) instead
|
|
of filing an issue.
|
|
|
|
When filing an issue, please include the following information if
|
|
possible as well as a description of the problem. Make sure you test
|
|
with the [latest beta of rclone](http://beta.rclone.org/):
|
|
|
|
* Rclone version (eg output from `rclone -V`)
|
|
* Which OS you are using and how many bits (eg Windows 7, 64 bit)
|
|
* The command you were trying to run (eg `rclone copy /tmp remote:tmp`)
|
|
* A log of the command with the `-vv` flag (eg output from `rclone -vv copy /tmp remote:tmp`)
|
|
* if the log contains secrets then edit the file with a text editor first to obscure them
|
|
|
|
## Submitting a pull request ##
|
|
|
|
If you find a bug that you'd like to fix, or a new feature that you'd
|
|
like to implement then please submit a pull request via Github.
|
|
|
|
If it is a big feature then make an issue first so it can be discussed.
|
|
|
|
You'll need a Go environment set up with GOPATH set. See [the Go
|
|
getting started docs](https://golang.org/doc/install) for more info.
|
|
|
|
First in your web browser press the fork button on [rclone's Github
|
|
page](https://github.com/ncw/rclone).
|
|
|
|
Now in your terminal
|
|
|
|
go get github.com/ncw/rclone
|
|
cd $GOPATH/src/github.com/ncw/rclone
|
|
git remote rename origin upstream
|
|
git remote add origin git@github.com:YOURUSER/rclone.git
|
|
|
|
Make a branch to add your new feature
|
|
|
|
git checkout -b my-new-feature
|
|
|
|
And get hacking.
|
|
|
|
When ready - run the unit tests for the code you changed
|
|
|
|
go test -v
|
|
|
|
Note that you may need to make a test remote, eg `TestSwift` for some
|
|
of the unit tests.
|
|
|
|
Note the top level Makefile targets
|
|
|
|
* make check
|
|
* make test
|
|
|
|
Both of these will be run by Travis when you make a pull request but
|
|
you can do this yourself locally too. These require some extra go
|
|
packages which you can install with
|
|
|
|
* make build_dep
|
|
|
|
Make sure you
|
|
|
|
* Add documentation for a new feature (see below for where)
|
|
* Add unit tests for a new feature
|
|
* squash commits down to one per feature
|
|
* rebase to master `git rebase master`
|
|
|
|
When you are done with that
|
|
|
|
git push origin my-new-feature
|
|
|
|
Go to the Github website and click [Create pull
|
|
request](https://help.github.com/articles/creating-a-pull-request/).
|
|
|
|
You patch will get reviewed and you might get asked to fix some stuff.
|
|
|
|
If so, then make the changes in the same branch, squash the commits,
|
|
rebase it to master then push it to Github with `--force`.
|
|
|
|
## Testing ##
|
|
|
|
rclone's tests are run from the go testing framework, so at the top
|
|
level you can run this to run all the tests.
|
|
|
|
go test -v ./...
|
|
|
|
rclone contains a mixture of unit tests and integration tests.
|
|
Because it is difficult (and in some respects pointless) to test cloud
|
|
storage systems by mocking all their interfaces, rclone unit tests can
|
|
run against any of the backends. This is done by making specially
|
|
named remotes in the default config file.
|
|
|
|
If you wanted to test changes in the `drive` backend, then you would
|
|
need to make a remote called `TestDrive`.
|
|
|
|
You can then run the unit tests in the drive directory. These tests
|
|
are skipped if `TestDrive:` isn't defined.
|
|
|
|
cd drive
|
|
go test -v
|
|
|
|
You can then run the integration tests which tests all of rclone's
|
|
operations. Normally these get run against the local filing system,
|
|
but they can be run against any of the remotes.
|
|
|
|
cd ../fs
|
|
go test -v -remote TestDrive:
|
|
go test -v -remote TestDrive: -subdir
|
|
|
|
If you want to run all the integration tests against all the remotes,
|
|
then run in that directory
|
|
|
|
go run test_all.go
|
|
|
|
## Writing Documentation ##
|
|
|
|
If you are adding a new feature then please update the documentation.
|
|
|
|
If you add a new flag, then if it is a general flag, document it in
|
|
`docs/content/docs.md` - the flags there are supposed to be in
|
|
alphabetical order. If it is a remote specific flag, then document it
|
|
in `docs/content/remote.md`.
|
|
|
|
The only documentation you need to edit are the `docs/content/*.md`
|
|
files. The MANUAL.*, rclone.1, web site etc are all auto generated
|
|
from those during the release process. See the `make doc` and `make
|
|
website` targets in the Makefile if you are interested in how. You
|
|
don't need to run these when adding a feature.
|
|
|
|
Documentation for rclone sub commands is with their code, eg
|
|
`cmd/ls/ls.go`.
|
|
|
|
## Making a release ##
|
|
|
|
There are separate instructions for making a release in the RELEASE.md
|
|
file.
|
|
|
|
## Updating the vendor dirctory ##
|
|
|
|
Do these commands to update the entire build directory to the latest
|
|
version of all the dependencies. This should be done early in the
|
|
release cycle. Individual dependencies can be added with `godep get`.
|
|
|
|
* make build_dep
|
|
* make update
|
|
|
|
## Writing a new backend ##
|
|
|
|
Choose a name. The docs here will use `remote` as an example.
|
|
|
|
Note that in rclone terminology a file system backend is called a
|
|
remote or an fs.
|
|
|
|
Research
|
|
|
|
* Look at the interfaces defined in `fs/fs.go`
|
|
* Study one or more of the existing remotes
|
|
|
|
Getting going
|
|
|
|
* Create `remote/remote.go` (copy this from a similar fs)
|
|
* Add your fs to the imports in `fs/all/all.go`
|
|
|
|
Unit tests
|
|
|
|
* Create a config entry called `TestRemote` for the unit tests to use
|
|
* Add your fs to the end of `fstest/fstests/gen_tests.go`
|
|
* generate `remote/remote_test.go` unit tests `cd fstest/fstests; go generate`
|
|
* Make sure all tests pass with `go test -v`
|
|
|
|
Integration tests
|
|
|
|
* Add your fs to `fs/test_all.go`
|
|
* Make sure integration tests pass with
|
|
* `cd fs`
|
|
* `go test -v -remote TestRemote:` and
|
|
* `go test -v -remote TestRemote: -subdir`
|
|
|
|
Add your fs to the docs
|
|
|
|
* `README.md` - main Github page
|
|
* `docs/content/remote.md` - main docs page
|
|
* `docs/content/overview.md` - overview docs
|
|
* `docs/content/docs.md` - list of remotes in config section
|
|
* `docs/content/about.md` - front page of rclone.org
|
|
* `docs/layouts/chrome/navbar.html` - add it to the website navigation
|
|
* `bin/make_manual.py` - add the page to the `docs` constant
