4## Prerequisites
5This guide assumes that you have:
6- a GPG key matching your GitHub authentication credentials
7 - i.e., the email address identified by the GPG key is the same as the one in your `~/.gitconfig`
8- a GitHub fork of Shaarli
9- a local clone of your Shaarli fork, with the following remotes:
10 - `origin` pointing to your GitHub fork
11 - `upstream` pointing to the main Shaarli repository
12- maintainer permissions on the main Shaarli repository, to:
13 - push the signed tag
14 - create a new release
15- [Composer](https://getcomposer.org/) needs to be installed
16- The [venv](https://docs.python.org/3/library/venv.html) Python 3 module needs to be installed for HTML documentation generation.
17
18## GitHub release draft and `CHANGELOG.md`
19See http://keepachangelog.com/en/0.3.0/ for changelog formatting.
20
21### GitHub release draft
22GitHub allows drafting the release note for the upcoming release, from the [Releases](https://github.com/shaarli/Shaarli/releases) page. This way, the release note can be drafted while contributions are merged to `master`.
23
24### `CHANGELOG.md`
25This file should contain the same information as the release note draft for the upcoming version.
26
27Update it to:
28- add new entries (additions, fixes, etc.)
29- mark the current version as released by setting its date and link
30- add a new section for the future unreleased version
31
32```bash
33$ cd /path/to/shaarli
34
35$ nano CHANGELOG.md
36
37[...]
38## vA.B.C - UNRELEASED

42[...]
43```
44
45
46## Increment the version code, updated docs, create and push a signed tag
47### Generate documentation
48```bash
49$ cd /path/to/shaarli
50
51# create a new branch
52$ git fetch upstream
53$ git checkout upstream/master -b v0.5.0
54
55# rebuild the HTML documentation from Markdown
56$ make htmlpages
57
58# commit the changes
59$ git add doc
60$ git commit -s -m "Generate documentation for v0.5.0"
61
62# push the commit on your GitHub fork
63$ git push origin v0.5.0
64```
65
66### Create and merge a Pull Request
67This one is pretty straightforward ;-)
68
69### Bump Shaarli version to v0.x branch
70
71```
72$ git checkout master
73$ git fetch upstream
74$ git pull upstream master
75
76# IF the branch doesn't exists
77$ git checkout -b v0.5
78# OR if the branch already exists
79$ git checkout v0.5
80$ git rebase upstream/master
81
82# Bump shaarli version from dev to 0.5.0, **without the `v`**
83$ vim shaarli_version.php
84$ git add shaarli_version
85$ git commit -s -m "Bump Shaarli version to v0.5.0"
86$ git push upstream v0.5
87```
88
89### Create and push a signed tag
90```bash
91# update your local copy
92$ git checkout v0.5
93$ git fetch upstream
94$ git pull upstream v0.5
95
96# create a signed tag
97$ git tag -s -m "Release v0.5.0" v0.5.0
98
99# push it to "upstream"
100$ git push --tags upstream
101```
102
103### Verify a signed tag
104[`v0.5.0`](https://github.com/shaarli/Shaarli/releases/tag/v0.5.0) is the first GPG-signed tag pushed on the Community Shaarli.
105
106Let's have a look at its signature!
107
108```bash
109$ cd /path/to/shaarli
110$ git fetch upstream
111
112# get the SHA1 reference of the tag
113$ git show-ref tags/v0.5.0
114f7762cf803f03f5caf4b8078359a63783d0090c1 refs/tags/v0.5.0
115
116# verify the tag signature information
117$ git verify-tag f7762cf803f03f5caf4b8078359a63783d0090c1
118gpg: Signature made Thu 30 Jul 2015 11:46:34 CEST using RSA key ID 4100DF6F
119gpg: Good signature from "VirtualTam <virtualtam@flibidi.net>" [ultimate]
120```
121
122## Publish the GitHub release
123### Update release badges
124Update `README.md` so version badges display and point to the newly released Shaarli version(s), in the `master` branch.
125
126### Create a GitHub release from a Git tag
127From the previously drafted release:
128- edit the release notes (if needed)
129- specify the appropriate Git tag
130- publish the release
131- profit!
132
133### Generate and upload all-in-one release archives
134Users with a shared hosting may have:
135- no SSH access
136- no possibility to install PHP packages or server extensions
137- no possibility to run scripts
138
139To ease Shaarli installations, it is possible to generate and upload additional release archives,
140that will contain Shaarli code plus all required third-party libraries.
141
142**From the `v0.5` branch:**
143
144```bash
145$ make release_archive
146```
147
148This will create the following archives:
149- `shaarli-vX.Y.Z-full.tar`
150- `shaarli-vX.Y.Z-full.zip`
151
152The archives need to be manually uploaded on the previously created GitHub release.
153
154### Update `stable` and `latest` branches
155
156```
157$ git checkout latest
158# latest release
159$ git merge v0.5.0
160# fix eventual conflicts
161$ make test
162$ git push upstream latest
163$ git checkout stable
164# latest previous major
165$ git merge v0.4.5
166# fix eventual conflicts
167$ make test
168$ git push upstream stable
169```
