2019-04-25Merge branch 'sg/overlong-progress-fix'Junio C Hamano
Updating the display with progress message has been cleaned up to deal better with overlong messages. * sg/overlong-progress-fix: progress: break too long progress bar lines progress: clear previous progress update dynamically progress: assemble percentage and counters in a strbuf before printing progress: make display_progress() return void
2019-04-05progress: make display_progress() return voidSZEDER Gábor
Ever since the progress infrastructure was introduced in 96a02f8f6d (common progress display support, 2007-04-18), display_progress() has returned an int, telling callers whether it updated the progress bar or not. However, this is: - useless, because over the last dozen years there has never been a single caller that cared about that return value. - not quite true, because it doesn't print a progress bar when running in the background, yet it returns 1; see 85cb8906f0 (progress: no progress in background, 2015-04-13). The related display_throughput() function returned void already upon its introduction in cf84d51c43 (add throughput to progress display, 2007-10-30). Let's make display_progress() return void, too. While doing so several return statements in display() become unnecessary, remove them. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-03-22progress: add sparse mode to force 100% complete messageJeff Hostetler
Add new start_sparse_progress() and start_delayed_sparse_progress() constructors and "sparse" flag to struct progress. Teach stop_progress() to force a 100% complete progress message before printing the final "done" message when "sparse" is set. Calling display_progress() for every item in a large set can be expensive. If callers try to filter this for performance reasons, such as emitting every k-th item, progress would not reach 100% unless they made a final call to display_progress() with the item count before calling stop_progress(). Now this is automatic when "sparse" is set. Signed-off-by: Jeff Hostetler <jeffhost@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-11-15progress: fix progress meters when dealing with lots of workElijah Newren
The possibility of setting merge.renameLimit beyond 2^16 raises the possibility that the values passed to progress can exceed 2^32. Use uint64_t, because it "ought to be enough for anybody". :-) Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-08-19progress: simplify "delayed" progress APIJunio C Hamano
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>
2007-11-08nicer display of thin pack completionNicolas Pitre
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.

2007-11-05make display of total transferred more accurateNicolas Pitre
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>
2007-10-30add throughput to progress displayNicolas Pitre
This adds the ability for the progress code to also display transfer throughput when that makes sense. The math was inspired by commit c548cf4ee0737a321ffe94f6a97c65baf87281be from Linus. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This allows for better management of progress "object" existence, as well as making the progress display implementation more independent from its callers. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-04-23common progress display supportNicolas Pitre
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.
