5 | # An example hook script to mail out commit update information. This hook |
6 | # sends emails listing new revisions to the repository introduced by the | |
7 | # change being reported. The rule is that (for branch updates) each commit | |
8 | # will appear on one email and one email only. | |

15a2f530 GP |
10 | # This hook is stored in the contrib/hooks directory. Your distribution |
11 | # will have put this somewhere standard. You should make this script | |
12 | # executable then link to it in the repository you would like to use it in. | |
13 | # For example, on debian the hook is stored in | |
14 | # /usr/share/doc/git-core/contrib/hooks/post-receive-email: | |
4557e0de AP |

19 | # | |

20 | # This hook script assumes it is enabled on the central repository of a |
21 | # project, with all users pushing only to it and not between each other. It | |
22 | # will still work if you don't operate in that style, but it would become | |
23 | # possible for the email to be from someone other than the person doing the | |
24 | # push. | |

241 | # Consider this: | |
242 | # 1 --- 2 --- O --- X --- 3 --- 4 --- N | |
243 | # | |
244 | # O is $oldrev for $refname | |
245 | # N is $newrev for $refname | |
246 | # X is a revision pointed to by some other ref, for which we may | |
247 | # assume that an email has already been generated. | |
248 | # In this case we want to issue an email containing only revisions | |
249 | # 3, 4, and N. Given (almost) by | |
250 | # | |
251 | # git-rev-list N ^O --not --all | |
252 | # | |
253 | # The reason for the "almost", is that the "--not --all" will take | |
254 | # precedence over the "N", and effectively will translate to | |
255 | # | |
256 | # git-rev-list N ^O ^X ^N | |
257 | # | |
15a2f530 GP |
258 | # So, we need to build up the list more carefully. git-rev-parse |
259 | # will generate a list of revs that may be fed into git-rev-list. | |
260 | # We can get it to make the "--not --all" part and then filter out | |
261 | # the "^N" with: | |
4557e0de AP |
262 | # |
263 | # git-rev-parse --not --all | grep -v N | |
264 | # | |
265 | # Then, using the --stdin switch to git-rev-list we have effectively | |
266 | # manufactured | |
267 | # | |
268 | # git-rev-list N ^O ^X | |
269 | # | |
270 | # This leaves a problem when someone else updates the repository | |
15a2f530 GP |
271 | # while this script is running. Their new value of the ref we're |
272 | # working on would be included in the "--not --all" output; and as | |
273 | # our $newrev would be an ancestor of that commit, it would exclude | |
274 | # all of our commits. What we really want is to exclude the current | |
275 | # value of $refname from the --not list, rather than N itself. So: | |
4557e0de AP |
276 | # |
277 | # git-rev-parse --not --all | grep -v $(git-rev-parse $refname) | |
278 | # | |
15a2f530 GP |
279 | # Get's us to something pretty safe (apart from the small time |
280 | # between refname being read, and git-rev-parse running - for that, | |
281 | # I give up) | |
4557e0de AP |
282 | # |
283 | # | |
284 | # Next problem, consider this: | |
285 | # * --- B --- * --- O ($oldrev) | |
286 | # \ | |
287 | # * --- X --- * --- N ($newrev) | |
288 | # | |
15a2f530 GP |
289 | # That is to say, there is no guarantee that oldrev is a strict |
290 | # subset of newrev (it would have required a --force, but that's | |
291 | # allowed). So, we can't simply say rev-list $oldrev..$newrev. | |
292 | # Instead we find the common base of the two revs and list from | |
293 | # there. | |
4557e0de | 294 | # |
15a2f530 GP |
295 | # As above, we need to take into account the presence of X; if |
296 | # another branch is already in the repository and points at some of | |
297 | # the revisions that we are about to output - we don't want them. | |
298 | # The solution is as before: git-rev-parse output filtered. | |
4557e0de | 299 | # |
15a2f530 | 300 | # Finally, tags: 1 --- 2 --- O --- T --- 3 --- 4 --- N |
4557e0de AP |
301 | # |
302 | # Tags pushed into the repository generate nice shortlog emails that | |
303 | # summarise the commits between them and the previous tag. However, | |
304 | # those emails don't include the full commit messages that we output | |
305 | # for a branch update. Therefore we still want to output revisions | |
306 | # that have been output on a tag email. | |
307 | # | |
15a2f530 GP |
308 | # Luckily, git-rev-parse includes just the tool. Instead of using |
