Patrick Steinhardt f6bb64df82 fetch: skip formatting updated refs with `--quiet` When fetching, Git will by default print a list of all updated refs in a nicely formatted table. In order to come up with this table, Git needs to iterate refs twice: first to determine the maximum column width, and a second time to actually format these changed refs. While this table will not be printed in case the user passes `--quiet`, we still go out of our way and do all these steps. In fact, we even do more work compared to not passing `--quiet`: without the flag, we will skip all references in the column width computation which have not been updated, but if it is set we will now compute widths for all refs. Fix this issue by completely skipping both preparation of the format and formatting data for display in case the user passes `--quiet`, improving performance especially with many refs. The following benchmark shows a nice speedup for a quiet mirror-fetch in a repository with 2.3M refs: Benchmark #1: HEAD~: git-fetch Time (mean ± σ): 26.929 s ± 0.145 s [User: 24.194 s, System: 4.656 s] Range (min … max): 26.692 s … 27.068 s 5 runs Benchmark #2: HEAD: git-fetch Time (mean ± σ): 25.189 s ± 0.094 s [User: 22.556 s, System: 4.606 s] Range (min … max): 25.070 s … 25.314 s 5 runs Summary 'HEAD: git-fetch' ran 1.07 ± 0.01 times faster than 'HEAD~: git-fetch' While at it, this patch also fixes `adjust_refcol_width()` such that it skips unchanged refs in case the user passed `--quiet`, where verbosity will be negative. While this function won't be called anymore if so, this brings the comment in line with actual code. Furthermore, needless `verbosity >= 0` checks are now removed in `store_updated_refs()`: we never print to the `note` buffer anymore in case `verbosity < 0`, so we won't end up in that code block anyway.

Git - fast, scalable, distributed revision control system

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 git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.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 git-security@googlegroups.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):

random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
"global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
"goddamn idiotic truckload of sh*t": when it breaks
