6 git-mktag - Creates a tag object with extra validation
18 By default mktag turns on the equivalent of
19 linkgit:git-fsck[1] `--strict` mode. Use `--no-strict` to
25 Reads a tag contents on standard input and creates a tag object. The
26 output is the new tag's <object> identifier.
28 This command is mostly equivalent to linkgit:git-hash-object[1]
29 invoked with `-t tag -w --stdin`. I.e. both of these will create and
30 write a tag found in `my-tag`:
33 git hash-object -t tag -w --stdin <my-tag
35 The difference is that mktag will die before writing the tag if the
36 tag doesn't pass a linkgit:git-fsck[1] check.
38 The "fsck" check done mktag is stricter than what linkgit:git-fsck[1]
39 would run by default in that all `fsck.<msg-id>` messages are promoted
40 from warnings to errors (so e.g. a missing "tagger" line is an error).
42 Extra headers in the object are also an error under mktag, but ignored
43 by linkgit:git-fsck[1]. This extra check can be turned off by setting
44 the appropriate `fsck.<msg-id>` varible:
46 git -c fsck.extraHeaderEntry=ignore mktag <my-tag-with-headers
50 A tag signature file, to be fed to this command's standard input,
51 has a very simple fixed format: four lines of
58 followed by some 'optional' free-form message (some tags created
59 by older Git may not have `tagger` line). The message, when it
60 exists, is separated by a blank line from the header. The
61 message part may contain a signature that Git itself doesn't
62 care about, but that can be verified with gpg.
