Subject: [[TIG][PATCH v2] 1/3] Add log_select function to find commit from context in log view
Date: Tue, 06 Aug 2013 00:58:19 -0400 [thread overview]
Message-ID: <1375765101-31461-2-git-send-email-a.kumar@alumni.iitm.ac.in> (raw)
In-Reply-To: <1375765101-31461-1-git-send-email-a.kumar@alumni.iitm.ac.in>
This commit introduces and uses the log_select function to find the
correct commit in the unsplit log view. In the log view, if one
scrolls down across a commit line, the current commit (as displayed in
the status bar) gets updated, but not so when scrolling upward across
a commit. The log_select function handles this scenario to do the
``right thing''. In addition, it introduces the log_state structure as
the private entry of the log view to hold a flag that decides whether
to re-evaluate the current commit based on scrolling.
