Following the suggestion of Phillip I've rebased my patch on master (745f681289)
and cherry-picking b0a3186140.
Base: 745f6812895b31c02b29bdfe4ae8e5498f776c26
with cherry-picked b0a3186140dbc7bd64cbc6ef733386a0f1eb6a4d
Outline:
2/6:
- Change commit message and description
3/6:
- add test for rebase -r
- add strict bounds while pushing ident date
5/6:
- bug fix: (following am's code) if --ignore-date is provided,
we should setenv GIT_COMMITTER_DATE to "".
- catch error when ident line is malformed
- push GIT_AUTHOR_DATE instead of providing it with --date so
that "git merge" can also use push_dates function
- add test for rebase -r
Rohit Ashiwal (6):
rebase -i: add --ignore-whitespace flag
sequencer: allow callers of read_author_script() to ignore fields
rebase -i: support --committer-date-is-author-date
sequencer: rename amend_author to author_to_rename
rebase -i: support --ignore-date
rebase: add --reset-author-date

Author: Rohit Ashiwal <rohit.ashiwal...@gmail.com>
- sequencer: add NULL checks under read_author_script
+ sequencer: allow callers of read_author_script() to ignore fields
- read_author_script reads name, email and author date from the author
- script. However, it does not check if the arguments are NULL. Adding
- NULL checks will allow us to selectively get the required value, for
- example:
+ The current callers of the read_author_script() function read name,
+ email and date from the author script. Allow callers to signal that
+ they are not interested in some among these three fields by passing
+ NULL.
- char *date;
- if (read_author_script(_path_, NULL, NULL, &date, _int_))
- die(_("failed to read author date"));
- /* needs to be free()'d */
- return date;
-
- Add NULL checks for better control over the information retrieved.
+ Note that fields that are ignored still must exist and be formatted
+ correctly in the author script.
