index-pack: restore "resolving deltas" progress meter Commit f08cbf60fe (index-pack: make quantum of work smaller, 2020-09-08) refactored the main loop in threaded_second_pass(), but also deleted the call to display_progress() at the top of the loop. This means that users typically see no progress at all during the delta resolution phase (and for large repositories, Git appears to hang). This looks like an accident that was unrelated to the intended change of that commit, since we continue to update nr_resolved_deltas in resolve_delta(). Let's restore the call to get that progress back. We'll also add a test that confirms we generate the expected progress. This isn't perfect, as it wouldn't catch a bug where progress was delayed to the end. That was probably possible to trigger when receiving a thin pack, because we'd eventually call display_progress() from fix_unresolved_deltas(), but only once after doing all the work. However, since our test case generates a complete pack, it reliably demonstrates this particular bug and its fix. And we can't do better without making the test racy.

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and
Documentation/git-<commandname>.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with
man gittutorial or
git help tutorial, and the documentation of each command with
man git-<commandname> or
git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt (
man gitcvs-migration or
git help cvs-migration if git is installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to email@example.com (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just “subscribe git” in the body to firstname.lastname@example.org. The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list email@example.com.
The maintainer frequently sends the “What's cooking” reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
