**Guidelines, overview of maintenance process, etc.**

*“Thou shall GPG-sign.”*

# Git config

## GPG signing

While contributors are suggested to use GPG, as a maintainer you **are
required** to use GPG to sign commits & merges.

If you don't have GPG signing set up yet, now is the moment to do it.

[Config, etc.](/CONTRIBUTING.md#git-config)


## SSH

Preferably use SSH.

There are quite a few articles about that:
https://help.github.com/categories/ssh/

## Useful aliases

Check whether commits are GPG-signed with `git logs`

```
git config --global alias.logs 'log --show-signature'
```

# Commits

- **always** use [commit message format]
- **always** GPG-sign your commits.
- it's preferable to make a PR with changes that you're about to commit.

  Yes, there might be a situation where something has to be fixed "right now"
  on master..

  Perhaps a security fix, who knows what future holds. If it's not *that*
  important, you're still better off making a PR. Even when you'll just
  fast-forward commits from PR onto the `master` branch.

  Reasoning for it is that it's always hard to catch bugs/mistakes that you
  create, while someone else who just briefly looked at the changeset possibly
  can see a problem `:)`

# Pull requests

- **do not** push any `Merge`, `Squash & Merge`, etc. buttons on the website!
  The only allowed way of merging is locally, since otherwise merge will not
  be signed, and websites can fairly well mess things up.
- **always** test PR that is being merged.
- **always** GPG-sign PR that you're merging.

  Commits that are about to be merged don't have to be signed, but the
  merge-commit **must** be signed. To simplify the process, and ensure that
  things are done "right", it's preferable to use the [`merge-pr.sh`] script,
  which does that for you automatically.
- **use** [`merge-pr.sh`] script to merge PRs. First checkout the target
  branch, usually either `master` or a release dev branch e.g. `v1.17-dev`,
  make sure it's up to date with qTox/qTox, then e.g. `./merge-pr.sh 1234`.

  You don't have to use it, but then you're running into risk of breaking
  travis build of master & other PRs, since it verifies all commit messages,
  indlucing merge messages.

  Risk, that can be avoided when one doesn't type manually merge message :wink:
- **might want** to use [`test-pr.sh`].
- give a PR some "breathing space" right after it's created – i.e. merging
  something right away can lead to bugs & regressions suddenly popping up, thus
  it's preferable to wait at least a day or so, to let people test & comment on
  the PR before merging.
  - with trivial changes, like fixing typos or something along those lines,
    feel free to merge right away.
- if PR requires some changes, comment what parts need to be adjusted, and
  assign the `PR-needs-changes` label – after requested changes are done,
  remove the label.
- if PR doesn't apply properly on top of current master (when using
  [`merge-pr.sh`] script), request a rebase and tag PR with `PR-needs-rebase`.
- if a PR requires changes but there has been no activity from the PR submitter
  for more than 2 months, close the PR.

# Continous Integration

qTox nightly builds can be found in [qTox-nightly-release]. Should one build
fail, it is important to restart the whole Travis CI build and not just a
single job. The tool managing the nightly builds deletes all build artifacts
on any job failure, so all need to be rebuilt.

# Issues

- tag issues
  - `up for grabs` tag should be used whenever no one is currently working on
    the issue, and you're not going to work on it in foreseeable future (hours,
    day or two).
  - when you request more info to be provided in the issue, tag it with
    `I-need-info`. Remove tag once needed info has been provided.
    - sometimes there are issue with only one comment, and no reply to query
      for more info. Those issues usually can be closed after some period,
      preferably after a month or more with no reply. To search for them, you
      can specify time period when issue with a given tag was last updated,
      e.g.: `label:I-need-info updated:<2016-03-01`.
- if you're going to fix the issue, assign yourself to it.
- when closing an issue, preferably state the reason why it was closed, unless
  it was closed automatically by commit message.
- when issue is a duplicate, tag it with `duplicate`, and issue that it was a
  duplicate of, tag with higher `duplicates:#`


# Translations from Weblate

Weblate provides an easy way for people to translate qTox. On one hand, it does
require a bit more attention & regular checking whether there are new
translations, on the other, it lessened problems that were happening with
"manual" way of providing translations.

To get translations into qTox:

1. Go to `https://hosted.weblate.org/projects/tox/qtox/#repository` and lock
   the repository for translations.
2. Make sure you have git setup to automatically gpg sign commits.
3. To update translated strings from Weblate, in the root of the qTox
   repository execute the script `tools/update-weblate.sh`
4. If a new translation language has been added, update the following files:
    - `CMakeLists.txt`
    - `src/widget/form/settings/generalform.cpp`
    - `translations/README.md`
    - `translations/i18n.pri`
    - `translations/translations.qrc`
5. To update translatable strings from qTox for Weblate, run
    `./tools/update-translation-files.sh ALL`
6. Checkout a new branch with e.g. `git checkout -b update_weblate` and open
   a Pull Request for it on Github.
7. After the Pull Request has been merged, `reset` Weblate to master and
   unlock it.

# Releases

## Tagging scheme

- tag versions that are to be released, make sure that they are GPG-signed,
  i.e. `git tag -s v1.8.0`
- use semantic versions for tags: `vMAJOR.MINOR.PATCH`
  - `MAJOR` – bump version when there are breaking changes to video, audio,
    text chats, groupchats, file transfers, and any other basic functionality.
    For other things, `MINOR` and `PATCH` are to be bumped.
  - `MINOR` – bump version when there are:
    - new features added
    - UI/feature breaking changes
    - other non-breaking changes
  - `PATCH` – bump when there have been only fixes added. If changes include
    something more than just bugfixes, bump `MAJOR` or `MINOR` version
    accordingly.
- bumping a higher-level version "resets" lower-version numbers, e.g.
  `v1.7.1 → v2.0.0`

## Steps for release

### Before tagging

- Format all code using the [`./tools/format-code.sh`] script
- Update version number for windows/osx packages using the
  [`./tools/update-versions.sh`] script, e.g. `./tools/update-versions.sh
  1.11.0`
- Update toxcore version number to the latest tag. Currently this needs to be
  done manually by `grep`ing for the current tag.
- Update the bootstrap nodelist at `./res/nodes.json` from https://nodes.tox.chat/json.
  This can be done by running [`./tools/update-nodes.sh`]
- Generate changelog with `clog`.
  - In a `MAJOR`/`MINOR` release tag should include information that changelog
    is located in the `CHANGELOG.md` file, e.g. `For details see CHANGELOG.md`
- To release a `PATCH` version after non-fix changes have landed on `master`
  branch, checkout latest `MAJOR`/`MINOR` version and `git cherry-pick -x`
  commits from `master` that you want `PATCH` release to include. Once
  cherry-picking has been done, tag HEAD of the branch.
  - When making a `PATCH` tag, include in tag message short summary of what the
    tag release fixes, and to whom it's interesting (often only some
    OSes/distributions would find given `PATCH` release interesting).

### After tagging

- Create and GPG-sign the tar.lz and tar.gz archives using
  [`./tools/create-tarballs.sh`] script, and upload both archives plus both
  signature files to the github release that was created by a Travis OSX
  release job.
- Update download links on https://tox.chat to point to the new release.
- Write a short blog post for https://github.com/qTox/blog/ and advertise the
  post on Tox IRC channels, popular Tox groups, reddit, or whatever other platforms.
- Open a PR to update the Flatpak manifest of our [Flathub repository] with the
  changes from [`./flatpak/io.github.qtox.qTox.json`].
- Comment to the PR with `bot, build` to execute a test build
- After the build passed for qTox on all architectures on
  [the Flathub build bot], merge the PR into the master branch of our
  [Flathub repository].


# How to become a maintainer?

Contribute, review & test pull requests, be active, oh and don't forget to
