5 | 13 | msuraev | The efforts to automate the release process are tracked in https://projects.osmocom.org/issues/1861 |
6 | |||
7 | 17 | msuraev | h2. When to make a new release |
8 | 1 | neels | |
9 | 16 | msuraev | Various Osmocom projects depend on others. |
10 | 1 | neels | |
11 | 28 | msuraev | *Proposed policy:* |
12 | 16 | msuraev | * master branch is expected to depend on latest master branches of depended-upon projects |
13 | 24 | msuraev | * make release of depended-upon projects if necessary before making non-library project release |
14 | * make sure that we have correct version dependencies before making non-library project release |
||
15 | 1 | neels | |
16 | 41 | msuraev | Alternatively/additionally we can make timely releases of non-library projects (and corresponding depended-upon libraries): |
17 | * once per XX months? |
||
18 | * before every OsmoDevCon? |
||
19 | * once YY items accumulated in TODO-RELEASE file |
||
20 | * when configuration/db format changes? |
||
21 | |||
22 | This would help to avoid batching too many changes together and to adhere to RERO better - see http://scalare.org/wp-content/uploads/2015/06/2015-Why-and-HowShould-OpenSource-ProjectsAdopt-Time-Based-Releases.pdf |

24 | 17 | msuraev | h2. How to make a new release |
25 | |||
26 | 39 | msuraev | First we outline specific steps for different project types, than common part. The @osmo-release.mk@ helper (installed by @libosmocore-dev@) available via @make release@ takes care of |
27 | 1 | neels | |
28 | 35 | msuraev | * version bump |
29 | * debian/changelog update |
||
30 | * commit |
||
31 | * sign |
||
32 | * tag |
||
33 | |||
34 | Feel free to send patches implementing further automation as you see fit. |
||
35 | |||
36 | 17 | msuraev | h3. Library release |
37 | 30 | msuraev | |
38 | 1 | neels | * modify @*_LIBVERSION@ in @Makefile.am@ as necessary according to TODO-RELEASE file |
39 | 34 | msuraev | |
40 | The release helper is trying to be smart about it and prevent making new library release with non-empty TODO-RELEASE file if @*_LIBVERSION@ is not adjusted beforehand. |
||
41 | 1 | neels | |
42 | h3. Non-library release |
||
43 | |||
44 | 35 | msuraev | Nothing special is required ATM. |
45 | 1 | neels | |
46 | 30 | msuraev | h3. Common steps |
47 | 1 | neels | |
48 | 30 | msuraev | Be default @make release@ prepares 'patch' release but you can manually specify any of 'major/minor/patch' as necessary - see http://semver.org/ for details. |
49 | 1 | neels | |
50 | 36 | msuraev | * @make REL=minor release@ |
51 | 30 | msuraev | * inspect the latest commit which was just created |
52 | 32 | msuraev | * adjust it if necessary and re-sign (see [[Make_a_new_release#How-to-retag-a-new-release|Re-tag new release]]) |
53 | 30 | msuraev | * push commit for review using @git review -f@ (see [[Gerrit]] for alternatives) |
54 | * push the release tag by @git push gerrit --tags@ |
||
55 | 38 | msuraev | * consider preparing article for https://osmocom.org/news/ and sending announcement to appropriate ML for major release once release commit passed the review |
56 | 1 | neels | |
57 | 44 | msuraev | h2. Which new release to make |
58 | |||
59 | Use following guidelines when choosing release type: |
||
60 | * major - ?? TBD |
||
61 | * minor - ?? TBD |
||
62 | * patch - ?? TBD |
||
63 | |||
64 | If unsure - ask in corresponding ML. |
||
65 | |||
66 | 43 | msuraev | h2. TODO-RELEASE file format and maintenance |
67 | 1 | neels | |
68 | 43 | msuraev | * all the strings which contain @#@ considered comment and will be ignored |
69 | * actual entries consists of 3 tab-separated fields: |
||
70 | # library - name of the library affected (should correspond to @lib*.pc.in@ file in project's root directory) |
||
71 | # what - API or ABI change (used as a guidance to properly bump @*_LIBVERSION@) |
||
72 | # description - textual description (will end up in changelog) |
||
73 | |||
74 | When change affecting library's API/ABI is made than new entry should be added to TODO-RELEASE according to the format above. The file will be claned-up automatically by @make release@ command. |
||
75 | |||
76 | h2. How to (re)tag a new release |
||
77 | |||
78 | 36 | msuraev | <pre> |
79 | git tag -s 0.4.0 -f -m "Release v0.4.0 on 2017-08-25." |
||
80 | </pre> |
||
81 | 30 | msuraev | |
82 | This will automatically (re)sign the latest commit. You can specify which commit to sign explicitly. |
||
83 | 3 | neels | |
84 | 1 | neels | Say, for example, the git hash is @012342abcdefg@ and the next open version is 0.1.3: |
85 | 9 | neels | <pre> |
86 | 1 | neels | git tag -s 0.1.3 012342abcdefg -m "release 0.1.3" |
87 | </pre> |
||
88 | 8 | neels | |
89 | 1 | neels | (If @gpg@ complains, see [[Make a new release#GPG-Have-a-matching-user-id|GPG: Have a matching user id]].) |
90 | 4 | neels | |
91 | 1 | neels | Verify that git picks up the new version tag: |
92 | <pre> |
||
93 | $ git describe |
||
94 | 0.1.3-3-g1f95179 |
||
95 | </pre> |
||
96 | 11 | neels | |
97 | 42 | msuraev | N. B: *For your local build, _nothing will change_ until you delete the @.version@ file and completely rebuild:* |
98 | 1 | neels | |
99 | <pre> |
||
100 | 10 | neels | rm .version |
101 | autoreconf -fi |
||
102 | 1 | neels | ./configure |
103 | make |
||
104 | cat .version |
||
105 | </pre> |
||
106 | |||
107 | This should show the same as @git describe@. |
||
108 | |||
109 | When you're convinced that all is in order, push the new tag: |
||
110 | |||
111 | <pre> |
||
112 | git push origin 0.1.3 |
||
113 | </pre> |
||
114 | 14 | neels | |
115 | 1 | neels | If anything went wrong, you can delete the tag (locally) by |
116 | 15 | msuraev | <pre> |
117 | 14 | neels | git tag -d 0.1.3 |
118 | 1 | neels | </pre> |
119 | 42 | msuraev | and, if you've already pushed it, by |
120 | <pre> |
||
121 | git push --delete origin 0.1.3 |
||
122 | </pre> |
||
123 | |||
124 | h2. Deprecation policy |
||
125 | |||
126 | Functions/interfaces marked as deprecated for X releases of type Y can be removed in next Z release. |
||
127 | |||
128 | TBD: what's appropriate value for X? which Y and Z (from major/minor/patch) should we use? |
||
129 | 1 | neels | |
130 | h2. GPG: Have a matching user id |
||
131 | |||
132 | By default, @git tag -s@ takes your author information to lookup the secret GPG key to sign a tag with. |
||
133 | If the author+email do not exactly match one of the key's @uid@s, you will get this error: |
||
134 | |||
135 | <pre> |
||
136 | gpg: signing failed: secret key not available |
||
137 | </pre> |
||
138 | |||
139 | Verify: say, your author+email info in your git config says "John Doe <john@doe.net>", try |
||
140 | <pre> |
||
141 | gpg --list-secret-keys "John Doe <john@doe.net>" |
||
142 | </pre> |
||
143 | If this fails, GPG won't find the right key automatically. |
||
144 | |||
145 | Ways to resolve: |
||
146 | |||
147 | * Use @git tag -u <key-id>@ |
||
148 | * Edit your secret key to add a uid that matches your author information |
||
149 | <pre> |
||
150 | gpg --edit-key john@doe.net |
||
151 | gpg> adduid |
||
152 | # enter details to match the git author |
||
153 | gpg> save |
||
154 | </pre> |
