2021-10-08pretty: colorize pattern matches in commit messagesLibravatar Hamza Mahfooz1-2/+5
The "git log" command limits its output to the commits that contain strings matched by a pattern when the "--grep=<pattern>" option is used, but unlike output from "git grep -e <pattern>", the matches are not highlighted, making them harder to spot. Teach the pretty-printer code to highlight matches from the "--grep=<pattern>", "--author=<pattern>" and "--committer=<pattern>" options (to view the last one, you may have to ask for --pretty=fuller). Also, it must be noted that we are effectively greping the content twice (because it would be a hassle to rework the existing matching code to do a /g match and then pass it all down to the coloring code), however it only slows down "git log --author=^H" on this repository by around 1-2% (compared to v2.33.0), so it should be a small enough slow down to justify the addition of the feature.

2021-09-14midx.c: respect 'pack.writeBitmapHashcache' when writing bitmapsLibravatar Taylor Blau1-0/+4
In the previous commit, the bitmap writing code learned to propagate values from an existing hash-cache extension into the bitmap that it is writing. Now that that functionality exists, let's expose it by teaching the 'git multi-pack-index' builtin to respect the `pack.writeBitmapHashCache` option so that the hash-cache may be written at all. Two minor points worth noting here: - The 'git multi-pack-index write' sub-command didn't previously read any configuration (instead this is handled in the base command). A separate handler is added here to respect this write-specific config option. - I briefly considered adding a 'bitmap_flags' field to the static options struct, but decided against it since it would require plumbing through a new parameter to the write_midx_file() function. Instead, a new MIDX-specific flag is added, which is translated to the corresponding bitmap one. Signed-off-by: Taylor Blau <me@ttaylorr.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-09-10ssh signing: verify signatures using ssh-keygenLibravatar Fabian Stelzer1-0/+35
To verify a ssh signature we first call ssh-keygen -Y find-principal to look up the signing principal by their public key from the allowedSignersFile. If the key is found then we do a verify. Otherwise we only validate the signature but can not verify the signers identity. Verification uses the gpg.ssh.allowedSignersFile (see ssh-keygen(1) "ALLOWED SIGNERS") which contains valid public keys and a principal (usually user@domain). Depending on the environment this file can be managed by the individual developer or for example generated by the central repository server from known ssh keys with push access. This file is usually stored outside the repository, but if the repository only allows signed commits/pushes, the user might choose to store it in the repository. To revoke a key put the public key without the principal prefix into gpg.ssh.revocationKeyring or generate a KRL (see ssh-keygen(1) "KEY REVOCATION LISTS"). The same considerations about who to trust for verification as with the allowedSignersFile apply. Using SSH CA Keys with these files is also possible. Add "cert-authority" as key option between the principal and the key to mark it as a CA and all keys signed by it as valid for this CA. See "CERTIFICATES" in ssh-keygen(1).

Implements the actual sign_buffer_ssh operation and move some shared cleanup code into a strbuf function Set gpg.format = ssh and user.signingkey to either a ssh public key string (like from an authorized_keys file), or a ssh key file. If the key file or the config value itself contains only a public key then the private key needs to be available via ssh-agent. gpg.ssh.program can be set to an alternative location of ssh-keygen. A somewhat recent openssh version (8.2p1+) of ssh-keygen is needed for this feature. Since only ssh-keygen is needed it can this way be installed seperately without upgrading your system openssh packages.

2021-08-27docs: use "character encoding" to refer to commit-object encodingLibravatar Jeff King1-1/+1
The word "encoding" can mean a lot of things (e.g., base64 or quoted-printable encoding in emails, HTML entities, URL encoding, and so on). The documentation for i18n.commitEncoding and i18n.logOutputEncoding uses the phrase "character encoding" to make this more clear. Let's use that phrase in other places to make it clear what kind of encoding we are talking about. This patch covers the gui.encoding option, as well as the --encoding option for git-log, etc (in this latter case, I word-smithed the sentence a little at the same time). That, coupled with the mention of iconv in the --encoding description, should make this more clear. The other spot I looked at is the working-tree-encoding section of gitattributes(5). But it gives specific examples of encodings that I think make the meaning pretty clear already. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2021-07-20doc: clarify description of 'submodule.recurse'Libravatar Philippe Blain1-2/+3
The doc for 'submodule.recurse' starts with "Specifies if commands recurse into submodles by default". This is not exactly true of all commands that have a '--recurse-submodules' option. For example, 'git pull --recurse-submodules' does not run 'git pull' in each submodule, but rather runs 'git submodule update --recursive' so that the submodule working trees after the pull matches the commits recorded in the superproject. Clarify that by just saying that it enables '--recurse-submodules'. Note that the way this setting interacts with 'fetch.recurseSubmodules' and 'push.recurseSubmodules', which can have other values than true or false, is already documented since 4da9e99e6e (doc: be more precise on (fetch|push).recurseSubmodules, 2020-04-06).

2021-07-15rename: bump limit defaults yet againLibravatar Elijah Newren2-2/+2
These were last bumped in commit 92c57e5c1d29 (bump rename limit defaults (again), 2011-02-19), and were bumped both because processors had gotten faster, and because people were getting ugly merges that caused problems and reporting it to the mailing list (suggesting that folks were willing to spend more time waiting). Since that time: * Linus has continued recommending kernel folks to set diff.renameLimit=0 (maps to 32767, currently) * Folks with repositories with lots of renames were happy to set merge.renameLimit above 32767, once the code supported that, to get correct cherry-picks * Processors have gotten faster * It has been discovered that the timing methodology used last time probably used too large example files. The last point is probably worth explaining a bit more: * The "average" file size used appears to have been average blob size in the linux kernel history at the time (probably v2.6.25 or something close to it). * Since bigger files are modified more frequently, such a computation weights towards larger files. * Larger files may be more likely to be modified over time, but are not more likely to be renamed -- the mean and median blob size within a tree are a bit higher than the mean and median of blob sizes in the history leading up to that version for the linux kernel. * The mean blob size in v2.6.25 was half the average blob size in history leading to that point * The median blob size in v2.6.25 was about 40% of the mean blob size in v2.6.25. * Since the mean blob size is more than double the median blob size, any file as big as the mean will not be compared to any files of median size or less (because they'd be more than 50% dissimilar). * Since it is the number of files compared that provides the O(n^2) behavior, median-sized files should matter more than mean-sized ones. The combined effect of the above is that the file size used in past calculations was likely about 5x too large. Combine that with a CPU performance improvement of ~30%, and we can increase the limits by a factor of sqrt(5/(1-.3)) = 2.67, while keeping the original stated time limits. Keeping the same approximate time limit probably makes sense for diff.renameLimit (there is no progress feedback in e.g. git log -p), but the experience above suggests merge.renameLimit could be extended significantly. In fact, it probably would make sense to have an unlimited default setting for merge.renameLimit, but that would likely need to be coupled with changes to how progress is displayed. (See https://lore.kernel.org/git/YOx+Ok%2FEYvLqRMzJ@coredump.intra.peff.net/ for details in that area.) For now, let's just bump the approximate time limit from 10s to 1m. (Note: We do not want to use actual time limits, because getting results that depend on how loaded your system is that day feels bad, and because we don't discover that we won't get all the renames until after we've put in a lot of work rather than just upfront telling the user there are too many files involved.) Using the original time limit of 2s for diff.renameLimit, and bumping merge.renameLimit from 10s to 60s, I found the following timings using the simple script at the end of this commit message (on an AWS c5.xlarge which reports as "Intel(R) Xeon(R) Platinum 8124M CPU @ 3.00GHz"): N Timing 1300 1.995s 7100 59.973s So let's round down to nice even numbers and bump the limits from 400->1000, and from 1000->7000. Here is the measure_rename_perf script (adapted from https://lore.kernel.org/git/20080211113516.GB6344@coredump.intra.peff.net/ in particular to avoid triggering the linear handling from basename-guided rename detection): #!/bin/bash n=$1; shift rm -rf repo mkdir repo && cd repo git init -q -b main mkdata() { mkdir $1 for i in `seq 1 $2`; do (sed "s/^/$i /" <../sample echo tag: $1 ) >$1/$i done } mkdata initial $n git add . git commit -q -m initial mkdata new $n git add . cd new for i in *; do git mv $i $i.renamed; done cd .. git rm -q -rf initial git commit -q -m new time git diff-tree -M -l0 --summary HEAD^ HEAD Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

A few places in the docs implied that rename/copy detection is always quadratic or that all (unpaired) files were involved in the quadratic portion of rename/copy detection. The following two commits each introduced an exception to this: 9027f53cb505 (Do linear-time/space rename logic for exact renames, 2007-10-25) bd24aa2f97a0 (diffcore-rename: guide inexact rename detection based on basenames, 2021-02-14) (As a side note, for copy detection, the basename guided inexact rename detection is turned off and the exact renames will only result in sources (without the dests) being removed from the set of files used in quadratic detection. So, for copy detection, the documentation was closer to correct.) Avoid implying that all files involved in rename/copy detection are subject to the full quadratic algorithm.

In f6bebd121ac (git-send-email: add support for TLS via Net::SMTP::SSL, 2008-06-25) the --smtp-ssl command-line option was documented as deprecated, later in 65180c66186 (List send-email config options in config.txt., 2009-07-22) the "sendemail.smtpssl" configuration option was also documented as such. Then in in 3ff15040e22 (send-email: fix regression in sendemail.identity parsing, 2019-05-17) I unintentionally removed support for it by introducing a bug in read_config(). As can be seen from the diff context we've already returned unless $enc i defined, so it's not possible for us to reach the "elsif" branch here. This code was therefore already dead since Git v2.23.0. So let's just remove it. We were already 11 years into a stated deprecation period of this variable when 3ff15040e22 landed, now it's around 13. Since it hasn't worked anyway for around 2 years it looks like we can safely remove it. The --smtp-ssl option is still deprecated, if someone cares they can follow-up and remove that too, but unlike the config option that one could still be in use in the wild. I'm just removing this code that's provably unused already. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Another brown paper bag inconsistency fix for a new feature introduced during this cycle. * dl/stash-show-untracked-fixup: stash show: use stash.showIncludeUntracked even when diff options given
2021-05-22stash show: use stash.showIncludeUntracked even when diff options givenLibravatar Denton Liu1-3/+3
If options pertaining to how the diff is displayed is provided to `git stash show`, the command will ignore the stash.showIncludeUntracked configuration variable, defaulting to not showing any untracked files. This is unintuitive behaviour since the format of the diff output and whether or not to display untracked files are orthogonal. Use stash.showIncludeUntracked even when diff options are given. Of course, this is still overridable via the command-line options. Update the documentation to explicitly say which configuration variables will be overridden when a diff options are given.

2021-05-20doc: explain the use of color.pagerLibravatar Jeff King1-2/+3
The current documentation for color.pager is technically correct, but slightly misleading and doesn't really clarify the purpose of the variable. As explained in the original thread which added it: https://lore.kernel.org/git/E1G6zPH-00062L-Je@moooo.ath.cx/ the point is to deal with pagers that don't understand colors. And hence it being set to "true" is necessary for colorizing output to the pager, but not sufficient by itself (you must also have enabled one of the other color options, though note that these are set to "auto" by default these days).
