gitwhoareyounow
|
||
|
|
---------------
|
||
|
|
|
||
|
|
gitwhoareyounow is used to find a single identity for files that have been
|
||
|
|
renamed in the history of a project.
|
||
|
|
|
||
|
|
E.g., if a file foo.c is created in revision 1 (assuming successive revisions
|
||
|
|
numbered 1, 2, etc.) and renamed to bar.c in revision 2, gitwhoareyounow
|
||
|
|
would then return the name bar.c for this file in any revision we consider.
|
||
|
|
|
||
|
|
gitwhoareyounow has to be given a repository in which the historical commit
|
||
|
|
has been checked out, and the name the file had in that commit.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
$ git init
|
||
|
|
$ date >foo.c
|
||
|
|
# git add foo.c
|
||
|
|
# git commit -m "foo.c, rev 1"
|
||
|
|
$ git mv foo.c bar.c
|
||
|
|
$ git commit -m "foo.c renamed to bar.c, rev 2"
|
||
|
|
$ git checkout HEAD~1
|
||
|
|
$ ls
|
||
|
|
foo.c
|
||
|
|
$ gitwhoareyounow . foo.c
|
||
|
|
bar.c
|
||
|
|
|
||
|
|
|
||
|
|
Multiple files may use the same identity
|
||
|
|
- - - - - - - - - - - - - - - - - - - -
|
||
|
|
|
||
|
|
E.g., if a file foo.c is created in revision 1, deleted in revision 3, and
|
||
|
|
then a new file named foo.c is created in revision 4, gitwhoareyounow would
|
||
|
|
call both of them foo.c
|
||
|
|
|
||
|
|
|
||
|
|
Multiple files sharing the same identity can conflict
|
||
|
|
- - - - - - - - - - - - - - - - - - - - - - - - - - -
|
||
|
|
|
||
|
|
E.g., taking the first example with foo.c renamed to bar.c in revision 3, if
|
||
|
|
a file bar.c existed in revision 1 but was deleted in revision 2,
|
||
|
|
gitwhoareyounow running on revision 1 would identify both the foo.c and the
|
||
|
|
bar.c as bar.c
|
||
|
|
|
||
|
|
gitwhoareyounow does not try to resolve such conflicts. This is already
|
||
|
|
complex enough as it is :-)
