The builtin mechanism to capture a stacktrace in Go is to send a SIGQUIT to the running process. However, this mechanism is not avaiable on Windows. Thus, tweak the SIGINT handler to dump a stacktrace if the environment variable `RESTIC_DEBUG_STACKTRACE_SIGINT` is set.

Ways to Help Out
|
|
================
|
|
|
|
Thank you for your contribution! Please **open an issue first** (or add a
|
|
comment to an existing issue) if you plan to work on any code or add a new
|
|
feature. This way, duplicate work is prevented and we can discuss your ideas
|
|
and design first.
|
|
|
|
There are several ways you can help us out. First of all code contributions and
|
|
bug fixes are most welcome. However even "minor" details as fixing spelling
|
|
errors, improving documentation or pointing out usability issues are a great
|
|
help also.
|
|
|
|
The restic project uses the GitHub infrastructure (see the
|
|
[project page](https://github.com/restic/restic)) for all related discussions
|
|
as well as the [forum](https://forum.restic.net/) and the `#restic` channel
|
|
on [irc.libera.chat](https://kiwiirc.com/nextclient/#ircs://irc.libera.chat:6697/#restic).
|
|
|
|
If you want to find an area that currently needs improving have a look at the
|
|
open issues listed at the
|
|
[issues page](https://github.com/restic/restic/issues). This is also the place
|
|
for discussing enhancement to the restic tools.
|
|
|
|
If you are unsure what to do, please have a look at the issues, especially
|
|
those tagged
|
|
[minor complexity](https://github.com/restic/restic/labels/help%3A%20minor%20complexity)
|
|
or [good first issue](https://github.com/restic/restic/labels/help%3A%20good%20first%20issue).
|
|
If you are already a bit experienced with the restic internals, take a look
|
|
at the issues tagged as [help wanted](https://github.com/restic/restic/labels/help%3A%20wanted).

Reporting Bugs
|
|
==============
|
|
|
|
You've found a bug? Thanks for letting us know so we can fix it! It is a good
|
|
idea to describe in detail how to reproduce the bug (when you know how), what
|
|
environment was used and so on. Please tell us at least the following things:
|
|
|
|
* What's the version of restic you used? Please include the output of
|
|
`restic version` in your bug report.
|
|
* What commands did you execute to get to where the bug occurred?
|
|
* What did you expect?
|
|
* What happened instead?
|
|
* Are you aware of a way to reproduce the bug?
|
|
|
|
Remember, the easier it is for us to reproduce the bug, the earlier it will be
|
|
corrected!
|
|
|
|
In addition, you can instruct restic to create a debug log by setting the
|
|
environment variable `DEBUG_LOG` to a file, e.g. like this:
|
|
|
|
$ export DEBUG_LOG=/tmp/restic-debug.log
|
|
$ restic backup ~/work
|
|
|
|
Please be aware that the debug log file will contain potentially sensitive
|
|
things like file and directory names, so please either redact it before
|
|
uploading it somewhere or post only the parts that are really relevant.
|
|
|
|
If restic gets stuck, please also include a stacktrace in the description.
|
|
On non-Windows systems, you can send a SIGQUIT signal to restic or press
|
|
`Ctrl-\` to achieve the same result. This causes restic to print a stacktrace
|
|
and then exit immediatelly. This will not damage your repository, however,
|
|
it might be necessary to manually clean up stale lock files using
|
|
`restic unlock`.
|
|
|
|
On Windows, please set the environment variable `RESTIC_DEBUG_STACKTRACE_SIGINT`
|
|
to `true` and press `Ctrl-C` to create a stacktrace.
|
|
|
|
|
|
Development Environment
|
|
=======================
|
|
|
|
The repository contains the code written for restic in the directories
|
|
`cmd/` and `internal/`.
|
|
|
|
Make sure you have the minimum required Go version installed. Clone the repo
|
|
(without having `$GOPATH` set) and `cd` into the directory:
|
|
|
|
$ unset GOPATH
|
|
$ git clone https://github.com/restic/restic
|
|
$ cd restic
|
|
|
|
Then use the `go` tool to build restic:
|
|
|
|
$ go build ./cmd/restic
|
|
$ ./restic version
|
|
restic 0.14.0-dev (compiled manually) compiled with go1.19 on linux/amd64
|
|
|
|
You can run all tests with the following command:
|
|
|
|
$ go test ./...
|
|
|
|
Providing Patches
|
|
=================
|
|
|
|
You have fixed an annoying bug or have added a new feature? Very cool! Let's
|
|
get it into the project! The workflow we're using is also described on the
|
|
[GitHub Flow](https://guides.github.com/introduction/flow/) website, it boils
|
|
down to the following steps:
|
|
|
|
0. If you want to work on something, please add a comment to the issue on
|
|
GitHub. For a new feature, please add an issue before starting to work on
|
|
it, so that duplicate work is prevented.
|
|
|
|
1. Next, fork our project on GitHub if you haven't done so already.
|
|
|
|
2. Clone your fork of the repository locally and **create a new branch** for
|
|
your changes. If you are working on the code itself, please set up the
|
|
development environment as described in the previous section.
|
|
|
|
3. Commit your changes to the new branch as fine grained as possible, as
|
|
smaller patches, for individual changes, are easier to discuss and merge.
|
|
|
|
4. Push the new branch with your changes to your fork of the repository.
|
|
|
|
5. Create a pull request by visiting the GitHub website, it will guide you
|
|
through the process. Please [allow edits from maintainers](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/allowing-changes-to-a-pull-request-branch-created-from-a-fork).
|
|
|
|
6. You will receive comments on your code and the feature or bug that they
|
|
address. Maybe you need to rework some minor things, in this case push new
|
|
commits to the branch you created for the pull request (or amend the
|
|
existing commit, use common sense to decide which is better), they will be
|
|
automatically added to the pull request.
|
|
|
|
7. If your pull request changes anything that users should be aware of
|
|
(a bugfix, a new feature, ...) please add an entry as a new file in
|
|
`changelog/unreleased` including the issue number in the filename (e.g.
|
|
`issue-8756`). Use the template in `changelog/TEMPLATE` for the content.
|
|
It will be used in the announcement of the next stable release. While
|
|
writing, ask yourself: If I were the user, what would I need to be aware
|
|
of with this change?
|
|
|
|
8. Do not edit the man pages under `doc/man` or `doc/manual_rest.rst` -
|
|
these are autogenerated before new releases.
|
|
|
|
9. Once your code looks good and passes all the tests, we'll merge it. Thanks
|
|
a lot for your contribution!
|
|
|
|
Please provide the patches for each bug or feature in a separate branch and
|
|
open up a pull request for each, as this simplifies discussion and merging.
|
|
|
|
The restic project uses the `gofmt` tool for Go source indentation, so please
|
|
run
|
|
|
|
gofmt -w **/*.go
|
|
|
|
in the project root directory before committing. For each Pull Request, the
|
|
formatting is tested with `gofmt` for the latest stable version of Go.
|
|
Installing the script `fmt-check` from https://github.com/edsrzf/gofmt-git-hook
|
|
locally as a pre-commit hook checks formatting before committing automatically,
|
|
just copy this script to `.git/hooks/pre-commit`.
|
|
|
|
The project is using the program
|
|
[`golangci-lint`](https://github.com/golangci/golangci-lint) to run a list of
|
|
linters and checkers. It will be run on the code when you submit a PR. In order
|
|
to check your code beforehand, you can run `golangci-lint run` manually.
|
|
Eventually, we will enable `golangci-lint` for the whole code base. For now,
|
|
you can ignore warnings printed for lines you did not modify, those will be
|
|
ignored by the CI.
|
|
|
|
For each pull request, several different systems run the integration tests on
|
|
Linux, macOS and Windows. We won't merge any code that does not pass all tests
|
|
for all systems, so when a tests fails, try to find out what's wrong and fix
|
|
it. If you need help on this, please leave a comment in the pull request, and
|
|
we'll be glad to assist. Having a PR with failing integration tests is nothing
|
|
to be ashamed of. In contrast, that happens regularly for all of us. That's
|
|
what the tests are there for.
|
|
|
|
Git Commits
|
|
-----------
|
|
|
|
It would be good if you could follow the same general style regarding Git
|
|
commits as the rest of the project, this makes reviewing code, browsing the
|
|
history and triaging bugs much easier.
|
|
|
|
Git commit messages have a very terse summary in the first line of the commit
|
|
message, followed by an empty line, followed by a more verbose description or a
|
|
List of changed things. For examples, please refer to the excellent [How to
|
|
Write a Git Commit Message](https://chris.beams.io/posts/git-commit/).
|
|
|
|
If you change/add multiple different things that aren't related at all, try to
|
|
make several smaller commits. This is much easier to review. Using `git add -p`
|
|
allows staging and committing only some changes.
|
|
|
|
Code Review
|
|
===========
|
|
|
|
The restic project encourages actively reviewing the code, as it will store
|
|
your precious data, so it's common practice to receive comments on provided
|
|
patches.
|
|
|
|
If you are reviewing other contributor's code please consider the following
|
|
when reviewing:
|
|
|
|
* Be nice. Please make the review comment as constructive as possible so all
|
|
participants will learn something from your review.
|
|
|
|
As a contributor you might be asked to rewrite portions of your code to make it
|
|
fit better into the upstream sources.
