Subject: [PATCH v2 07/12] get_short_oid: learn to disambiguate by ^{tag}
Date: Tue, 1 May 2018 12:06:46 +0000 [thread overview]
Message-ID: <20180501120651.15886-8-avarab@gmail.com> (raw)
In-Reply-To: <20180501120651.15886-1-avarab@gmail.com>
In-Reply-To: <20180430220734.30133-1-avarab@gmail.com>
Add support for ^{tag} to the disambiguation logic. Before this ^{tag}
would simply be ignored:
$ git rev-parse e8f2^{tag}
error: short SHA1 e8f2 is ambiguous
hint: The candidates are:
hint: e8f2650052 tag v2.17.0
hint: e8f21caf94 commit 2013-06-24 - bash prompt: print unique detached HEAD abbreviated object name
hint: e8f26250fa commit 2017-02-03 - Merge pull request #996 from jeffhostetler/jeffhostetler/register_rename_src
hint: e8f2bc0c06 commit 2015-05-10 - Documentation: note behavior for multiple remote.url entries
hint: e8f2093055 tree
hint: e8f25a3a50 tree
hint: e8f28d537c tree
hint: e8f2cf6ec0 tree
hint: e8f21d02f7 blob
hint: e8f21d577c blob
hint: e8f2867228 blob
hint: e8f2a35526 blob
e8f2^{tag}
Now the logic added in ed1ca6025f ("peel_onion: disambiguate to favor
tree-ish when we know we want a tree-ish", 2013-03-31) has been
extended to support it.
$ git rev-parse e8f2^{tag}
