When we show a reflog selector (e.g., via "git log -g"), we perform some DWIM magic: while we normally show the entry's index (e.g., HEAD@{1}), if the user has given us a date with "--date", then we show a date-based select (e.g., HEAD@{yesterday}).
However, we don't want to trigger this magic if the alternate date format we got was from the "log.date" configuration; that is not sufficiently strong context for us to invoke this particular magic. To fix this, commit f4ea32f (improve reflog date/number heuristic, 2009-09-24) introduced a "date_mode_explicit" flag in rev_info. This flag is set only when we see a "--date" option on the command line, and we a vanilla date to the reflog code if the date was not explicit.
Later, commit 8f8f547 (Introduce new pretty formats %g[sdD] for reflog information, 2009-10-19) added another way to show selectors, and it did not respect the date_mode_explicit flag from f4ea32f.
This patch propagates the date_mode_explicit flag to the pretty-print code, which can then use it to pass the appropriate date field to the reflog code. This brings the behavior of "%gd" in line with the other formats, and means that its output is independent of any user configuration.
Signed-off-by: Jeff King <peff-AdEPDUrAXsQ@public.gmane.org> --- I'm not happy that users of pretty_print_context have to manually remember to copy in the date_mode_explicit flag; it would be nice if it just came with the date_mode field for free. But that would mean changing the type of date_mode to hold the extra bit, and would disrupt callers all over the code base.
