common progress display support Instead of having this code duplicated in multiple places, let's have a common interface for progress display. If someday someone wishes to display a cheezy progress bar instead then only one file will have to be changed. Note: I left merge-recursive.c out since it has a strange notion of progress as it apparently increase the expected total number as it goes. Someone with more intimate knowledge of what that is supposed to mean might look at converting it to the common progress interface.

make display of total transferred more accurate The throughput display needs a delay period before accounting and displaying anything. Yet it might be called after some amount of data has already been transferred. The display of total data is therefore accounted late and therefore smaller than the reality. Let's call display_throughput() with an absolute amount of transferred data instead of a relative number, and let the throughput code find the relative amount of data by itself as needed. This way the displayed total is always exact. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

struct progress *start_progress(const char *title, unsigned total);
progress: simplify "delayed" progress API We used to expose the full power of the delayed progress API to the callers, so that they can specify, not just the message to show and expected total amount of work that is used to compute the percentage of work performed so far, the percent-threshold parameter P and the delay-seconds parameter N. The progress meter starts to show at N seconds into the operation only if we have not yet completed P per-cent of the total work. Most callers used either (0%, 2s) or (50%, 1s) as (P, N), but there are oddballs that chose more random-looking values like 95%. For a smoother workload, (50%, 1s) would allow us to start showing the progress meter earlier than (0%, 2s), while keeping the chance of not showing progress meter for long running operation the same as the latter. For a task that would take 2s or more to complete, it is likely that less than half of it would complete within the first second, if the workload is smooth. But for a spiky workload whose earlier part is easier, such a setting is likely to fail to show the progress meter entirely and (0%, 2s) is more appropriate. But that is merely a theory. Realistically, it is of dubious value to ask each codepath to carefully consider smoothness of their workload and specify their own setting by passing two extra parameters. Let's simplify the API by dropping both parameters and have everybody use (0%, 2s). Oh, by the way, the percent-threshold parameter and the structure member were consistently misspelled, which also is now fixed ;-) Helped-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

void stop_progress(struct progress **progress);
nicer display of thin pack completion In the same spirit of prettifying Git's output display for mere mortals, here's a simple extension to the progress API allowing for a final message to be provided when terminating a progress line, and use it for the display of the number of objects needed to complete a thin pack, saving yet one more line of screen display.
