3 | # An example hook script to blocks unannotated tags from entering. | |
4 | # Called by "git receive-pack" with arguments: refname sha1-old sha1-new | |
5 | # | |
6 | # To enable this hook, rename this file to "update". | |

8 | # Config | |
9 | # ------ | |
10 | # hooks.allowunannotated | |
11 | # This boolean sets whether unannotated tags will be allowed into the | |
12 | # repository. By default they won't be. | |
13 | # hooks.allowdeletetag | |
14 | # This boolean sets whether deleting tags will be allowed in the | |
15 | # repository. By default they won't be. | |
16 | # hooks.allowmodifytag | |
17 | # This boolean sets whether a tag may be modified after creation. By default | |
18 | # it won't be. | |
19 | # hooks.allowdeletebranch | |
20 | # This boolean sets whether deleting branches will be allowed in the | |
21 | # repository. By default they won't be. | |
22 | # hooks.denycreatebranch | |
23 | # This boolean sets whether remotely creating branches will be denied | |
24 | # in the repository. By default this is allowed. | |
