git-submodule summary: show commit summary
This patch does the hard work to show submodule commit summary. For a modified submodule, a series of commits will be shown with the following command: git log --pretty='format:%m %s' \ --first-parent sha1_src...sha1_dst where the sha1_src is from the given super project commit and the sha1_dst is from the index or working tree (switched by --cached). For a deleted, added, or typechanged (blob<->submodule) submodule, only one single newest commit from the existing end (for example, src end for submodule deleted or type changed from submodule to blob) will be shown. If the src/dst sha1 for a submodule is missing in the submodule directory, a warning will be issued except in two cases where the submodule directory is deleted (type 'D') or typechanged to blob (one case of type 'T'). In the title line for a submodule, the src/dst sha1 and the number of commits (--first-parent) between the two commits will be shown. The following example demonstrates most cases. Example: commit summary for modified submodules sm1-sm5. -------------------------------------------- $ git submodule summary * sm1 354cd45...3f751e5 (4): < one line message for C < one line message for B > one line message for D > one line message for E * sm2 5c8bfb5...000000 (3): < one line message for F * sm3 354cd45...3f751e5: Warn: sm3 doesn't contain commit 354cd45 * sm4 354cd34(submodule)-> 235efa(blob) (1): < one line message for G * sm5 354cd34(blob)-> 235efa(submodule) (5): > one line message for H -------------------------------------------- Signed-off-by: Ping Yin <pkufranky@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
