8 | 8 | '''hooks for sending email push notifications |
|
9 | 9 | |
|
10 | 10 | This extension implements hooks to send email notifications when |
|
11 | 11 | changesets are sent from or received by the local repository. |
|
12 | 12 | |
|
13 | 13 | First, enable the extension as explained in :hg:`help extensions`, and |
|
14 | 14 | register the hook you want to run. ``incoming`` and ``changegroup`` hooks |
|
15 | 15 | are run when changesets are received, while ``outgoing`` hooks are for |
|
16 | 16 | changesets sent to another repository:: |
|
17 | 17 | |
|
18 | 18 | [hooks] |
|
19 | 19 | # one email for each incoming changeset |
|
20 | 20 | incoming.notify = python:hgext.notify.hook |
|
21 | 21 | # one email for all incoming changesets |
|
22 | 22 | changegroup.notify = python:hgext.notify.hook |
|
23 | 23 | |
|
24 | 24 | # one email for all outgoing changesets |
|
25 | 25 | outgoing.notify = python:hgext.notify.hook |
|
26 | 26 | |
|
27 | 27 | This registers the hooks. To enable notification, subscribers must |
|
28 | 28 | be assigned to repositories. The ``[usersubs]`` section maps multiple |
|
29 | 29 | repositories to a given recipient. The ``[reposubs]`` section maps |
|
30 | 30 | multiple recipients to a single repository:: |
|
31 | 31 | |
|
32 | 32 | [usersubs] |
|
33 | 33 | # key is subscriber email, value is a comma-separated list of repo patterns |
|
34 | 34 | user@host = pattern |
|
35 | 35 | |
|
36 | 36 | [reposubs] |
|
37 | 37 | # key is repo pattern, value is a comma-separated list of subscriber emails |
|
38 | 38 | pattern = user@host |
|
39 | 39 | |
|
40 | 40 | A ``pattern`` is a ``glob`` matching the absolute path to a repository, |
|
41 | 41 | optionally combined with a revset expression. A revset expression, if |
|
42 | 42 | present, is separated from the glob by a hash. Example:: |
|
43 | 43 | |
|
44 | 44 | [reposubs] |
|
45 | 45 | */widgets#branch(release) = qa-team@example.com |
|
46 | 46 | |
|
47 | 47 | This sends to ``qa-team@example.com`` whenever a changeset on the ``release`` |
|
48 | 48 | branch triggers a notification in any repository ending in ``widgets``. |
|
49 | 49 | |
|
50 | 50 | In order to place them under direct user management, ``[usersubs]`` and |
|
51 | 51 | ``[reposubs]`` sections may be placed in a separate ``hgrc`` file and |
|
52 | 52 | incorporated by reference:: |
|
53 | 53 | |
|
54 | 54 | [notify] |
|
55 | 55 | config = /path/to/subscriptionsfile |
|
56 | 56 | |
|
57 | 57 | Notifications will not be sent until the ``notify.test`` value is set |
|
58 | 58 | to ``False``; see below. |
|
59 | 59 | |
|
60 | 60 | Notifications content can be tweaked with the following configuration entries: |
|
61 | 61 | |
|
62 | 62 | notify.test |
|
63 | 63 | If ``True``, print messages to stdout instead of sending them. Default: True. |
|
64 | 64 | |
|
65 | 65 | notify.sources |
|
66 | 66 | Space-separated list of change sources. Notifications are activated only |
|
67 | 67 | when a changeset's source is in this list. Sources may be: |
|
68 | 68 | |
|
69 | 69 | :``serve``: changesets received via http or ssh |
|
70 | 70 | :``pull``: changesets received via ``hg pull`` |
|
71 | 71 | :``unbundle``: changesets received via ``hg unbundle`` |
|
72 | 72 | :``push``: changesets sent or received via ``hg push`` |
|
73 | 73 | :``bundle``: changesets sent via ``hg unbundle`` |
|
74 | 74 | |
|
75 | 75 | Default: serve. |
|
76 | 76 | |
|
77 | 77 | notify.strip |
|
78 | 78 | Number of leading slashes to strip from url paths. By default, notifications |
|
79 | 79 | reference repositories with their absolute path. ``notify.strip`` lets you |
|
80 | 80 | turn them into relative paths. For example, ``notify.strip=3`` will change |
|
81 | 81 | ``/long/path/repository`` into ``repository``. Default: 0. |
|
82 | 82 | |
|
83 | 83 | notify.domain |
|
84 | 84 | Default email domain for sender or recipients with no explicit domain. |
|
85 | 85 | |
|
86 | 86 | notify.style |
|
87 | 87 | Style file to use when formatting emails. |
|
88 | 88 | |
|
89 | 89 | notify.template |
|
90 | 90 | Template to use when formatting emails. |
|
91 | 91 | |
|
92 | 92 | notify.incoming |
|
93 | 93 | Template to use when run as an incoming hook, overriding ``notify.template``. |
|
94 | 94 | |
|
95 | 95 | notify.outgoing |
|
96 | 96 | Template to use when run as an outgoing hook, overriding ``notify.template``. |
|
97 | 97 | |
|
98 | 98 | notify.changegroup |
|
99 | 99 | Template to use when running as a changegroup hook, overriding |
|
100 | 100 | ``notify.template``. |
|
101 | 101 | |
|
102 | 102 | notify.maxdiff |
|
103 | 103 | Maximum number of diff lines to include in notification email. Set to 0 |
|
104 | 104 | to disable the diff, or -1 to include all of it. Default: 300. |
|
105 | 105 | |
|
106 | 106 | notify.maxsubject |
|
107 | 107 | Maximum number of characters in email's subject line. Default: 67. |
|
108 | 108 | |
|
109 | 109 | notify.diffstat |
|
110 | 110 | Set to True to include a diffstat before diff content. Default: True. |
|
111 | 111 | |
|
112 | 112 | notify.merge |
|
113 | 113 | If True, send notifications for merge changesets. Default: True. |
|
114 | 114 | |
|
115 | 115 | notify.mbox |
|
116 | 116 | If set, append mails to this mbox file instead of sending. Default: None. |
|
117 | 117 | |
|
118 | 118 | notify.fromauthor |
|
119 | 119 | If set, use the committer of the first changeset in a changegroup for |
|
120 | 120 | the "From" field of the notification mail. If not set, take the user |
|
121 | 121 | from the pushing repo. Default: False. |
|
122 | 122 | |
|
123 | 123 | If set, the following entries will also be used to customize the |
|
124 | 124 | notifications: |
|
125 | 125 | |
|
126 | 126 | email.from |
|
127 | 127 | Email ``From`` address to use if none can be found in the generated |
|
128 | 128 | email content. |
|
129 | 129 | |
|
130 | 130 | web.baseurl |
|
131 | 131 | Root repository URL to combine with repository paths when making |
|
132 | 132 | references. See also ``notify.strip``. |
