I studied + Economics, but I’ve always been curious about technology and how + Systems work behind the scenes. That curiosity led me to start teaching + myself web development, and over time I found myself drawn more + towards backend and systems-oriented work. + + I became especially interested in understanding how complex tools are + built and maintained, which led me to open source. I contributed to Git + as part of the Outreachy program, where I got to work on improving parts + of Git’s internal workflows. + + These days, I enjoy working on tools that make development smoother + for others, and I’m particularly interested in open source and + distributed systems. + +* **How did you initially become interested in contributing to Git, + and what motivated you to choose it as your Outreachy project?** + + I initially saw Git as just a tool I needed to get my work done. For a + long time, my workflow was basically just `git add`, `git commit`, `git push`, + and `git pull`, without thinking much about what was happening underneath. + That started to change when I ran into some particularly messy merge conflicts + that forced me to slow down and really question how Git was managing + history and combining changes. + + Around the same time, I was becoming more interested in systems in + general, thinking about tools like the kernel, systemd, and Git + itself, and how they work under the hood. That experience pushed me to + look deeper into Git’s internals, and I quickly realized how much + depth there was beneath the surface. + + When I came across the Outreachy project, choosing Git felt natural, I + wanted to challenge myself and contribute to a tool I had used for + years but didn’t fully understand, while learning from experienced + maintainers. + +* **How do you feel your contribution has impacted the Git community + or the broader open source ecosystem?** + + [My work](https://cloobtech.hashnode.dev/beginning-my-outreachy-opensource-internship-at-git-overview-and-project-description) + focused on reducing Git’s reliance on global state by refactoring + repository-specific variables into a more localized structure. Each repository + instance now manages its own configuration independently, improving modularity + and reducing the risk of cross-repository issues. + + Through this work, I came to appreciate how changes at this level contribute to + Git’s long-term direction, particularly efforts to make it more reusable as a + library. Even though these changes aren’t directly visible to users, they make + the system safer and easier to extend. + + Being part of that process gave me a deeper respect for the level of thought + and the care that goes into maintaining Git. + +* **Is there any aspect of Git that you now see differently after + having contributed to it?** + + Before contributing, I thought Git was just a bunch of commands I + typed every day. Working on it showed me a whole hidden world, + how configurations are saved and read, how each repository handles + its own settings, and what the index is really doing behind the scenes. + Some of it was so intricate I almost felt like Git was trolling me! + + Seeing all this up close turned what felt like a simple tool into a + carefully designed system, and it gave me a much deeper appreciation + for the thought and care behind every command. + +* **How do you balance your contributions with other responsibilities + like work or school?** + + At the moment, I’m not tied to a full-time job or school, but I spend a lot + of time learning new tech and doing freelance work. I usually dedicate small, + focused sessions to Git contributions, sometimes just an hour here or there, + and it’s surprising how much progress you can make that way. This rhythm lets + me keep learning, experimenting, and contributing without feeling overwhelmed. + +* **Can you share how Outreachy helped enhance your technical and + non-technical skills (like communication, project management, + etc.)?** + + Outreachy was a huge growth opportunity for me, both technically and personally. + On the technical side, I deepened my understanding of Git internals, learned to + work effectively in a large C codebase, and tackled complex refactoring of core + systems. On the non-technical side, I honed my communication skills by engaging + actively on the Git mailing list, responding to feedback, and documenting my + work clearly for others. The experience also helped me improve project + discipline, learning how to plan and iterate on tasks in a structured way. + +* **What was your biggest takeaway or learning from Outreachy that + you now apply regularly in your work?** + + My biggest takeaway from Outreachy was learning how even small, careful changes + can have a big impact in a large system like Git. During Outreachy, for even + the tiniest change, I had to run over 32,000 test cases just to be + sure it wouldn’t break anything! I approach my work by breaking tasks into + smaller steps, testing thoroughly, and thinking through the consequences + before making changes. This mindset has become a regular part of how I work, + whether I’m contributing to open source or building my own projects. + +* **What was the biggest challenge you faced during your contributions + to Git, and how did you overcome it?** + + The toughest part of contributing to Git was navigating its huge and complex + C codebase. I had to wrap my head around global variables, repository-specific + state, and how configs were stored and read. At first, it felt overwhelming, + and I constantly worried that even a small change might break something. + + I overcame this by tackling one piece at a time, reading the code carefully, + testing thoroughly, and admittedly, disturbing my mentors quite a bit! 😂 I’m + especially grateful to Christian Couder and Usman Akinyemi, who guided me + patiently. Christian taught me how to ask questions properly, showed me how to + debug effectively, and always encouraged me to think through problems step by + step. Usman was equally supportive, often checking in and joining coding + sessions with me. Both helped me understand Git’s internal architecture and + gave me the confidence to contribute safely and effectively. + +* **Have you thought about mentoring new GSoC / Outreachy students?** + + Yes, I have thought about mentoring future GSoC or Outreachy students. Since I’m + still relatively new to open source myself, I want to focus on contributing and + learning for now. However, I do hope to co-mentor in the next Outreachy program, + sharing what I’ve learned and helping others navigate the experience. + +* **If you could get a team of expert developers to work full time on + something in Git for a full year, what would it be?** + + If I had a team of expert developers working full time on Git for a year, I + would focus on further improving its modularity and internal architecture. + My goal would be to make Git easier to embed and reuse as a library, reducing + reliance on global state and improving the safety of multi-repository + operations. + + This would not only make Git more maintainable for contributors but also open + up new possibilities for other projects to integrate Git functionality + more easily. + +* **If you could remove something from Git without worrying about + backwards compatibility, what would it be?** + + If I could remove anything from Git without worrying about backwards + compatibility, I’d simplify some of the legacy parts of its internal state. + These older structures can be confusing and tricky to work with, and removing + them would make Git’s internals cleaner and easier to reason about. + +* **What upcoming features or changes in Git are you particularly + excited about?** + + I’m particularly excited about Git’s ongoing libification efforts, which make + it easier for other projects to embed and reuse Git functionality. Changes that + reduce global state and improve repository isolation also excite me, because + they make multi-repository operations safer and Git’s internals easier to work + with. I’m curious to see how these improvements will open up new possibilities + for both contributors and external tools that rely on Git. + +* **What is your favorite Git-related tool/library, outside of Git + itself?** + + I’d say my favorite Git-related tool is `gitingest`. It’s really handy for + exploring repositories programmatically and testing workflows. I’ve found it + especially useful while learning Git internals. + +* **What is your toolbox for interacting with the mailing list and for + development of Git?** + + I mainly use `git send-email` to submit patches, read threads on + [lore.kernel.org/git](https://lore.kernel.org/git), and reply via + Gmail. This setup helps me follow discussions and iterate on my + contributions smoothly. + + +* **How do you envision your own involvement with Git or other open + source projects in the future?** + + I’m here to stay in open source. I want to keep contributing to Git and other + projects, learning as I go, taking on bigger challenges, and helping new + contributors find their footing. Open source has become a big part of how I + grow as a developer, and I hope to keep giving back for years to come. + +* **What is your advice for people who want to start Git development? + Where and how should they start?** + + My advice for anyone starting Git development is to begin small and be curious. + A great resource I found helpful is the [MyFirstContribution](https://git-scm.com/docs/MyFirstContribution) + document. Start by reading the guides, experimenting locally, and submitting + small patches. Interacting with the mailing list, asking questions, and iterating + on feedback will help you learn and grow as a contributor. + +* **Would you recommend other students or contributors to participate + in the GSoC, Outreachy or other mentoring programs, working on + Git? Why? Do you have advice for them?** + + Absolutely, I would recommend programs like GSoC or Outreachy for anyone + interested in Git or open source. These programs provide structured mentorship, + exposure to real-world projects, and the chance to learn directly from + experienced developers. My advice is to start small, be curious, ask questions, + and don’t be afraid to iterate on feedback. Every contribution, no matter how + minor it may seem, is a valuable learning experience. + ## Other News From 4efd03c267f1f5f49c346325639310629b5b6b91 Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Sun, 29 Mar 2026 16:22:58 +0200 Subject: [PATCH 02/92] rn-133: add releases --- rev_news/drafts/edition-133.md | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) diff --git a/rev_news/drafts/edition-133.md b/rev_news/drafts/edition-133.md index ba0b0ec7d..466df15aa 100644 --- a/rev_news/drafts/edition-133.md +++ b/rev_news/drafts/edition-133.md @@ -253,6 +253,35 @@ __Git tools and sites__ ## Releases ++ Git for Windows [v2.52.0(2)](https://github.com/git-for-windows/git/releases/tag/v2.52.0.windows.2), +[v2.51.2(2)](https://github.com/git-for-windows/git/releases/tag/v2.51.2.windows.2), +[v2.53.0(2)](https://github.com/git-for-windows/git/releases/tag/v2.53.0.windows.2) ++ Bitbucket Data Center [10.2](https://confluence.atlassian.com/bitbucketserver/release-notes-872139866.html) ++ Gerrit Code Review [3.11.10](https://www.gerritcodereview.com/3.11.html#31110), +[3.11.9](https://www.gerritcodereview.com/3.11.html#3119), +[3.12.5](https://www.gerritcodereview.com/3.12.html#3125), +[3.12.6](https://www.gerritcodereview.com/3.12.html#3126), +[3.13.4](https://www.gerritcodereview.com/3.13.html#3134), +[3.13.5](https://www.gerritcodereview.com/3.13.html#3135), +[3.14.0-rc0](https://www.gerritcodereview.com/3.14.html#3140) ++ GitHub Enterprise [3.20.0](https://docs.github.com/enterprise-server@3.20/admin/release-notes#3.20.0), +[3.19.4](https://docs.github.com/enterprise-server@3.19/admin/release-notes#3.19.4), +[3.18.7](https://docs.github.com/enterprise-server@3.18/admin/release-notes#3.18.7), +[3.17.13](https://docs.github.com/enterprise-server@3.17/admin/release-notes#3.17.13), +[3.16.16](https://docs.github.com/enterprise-server@3.16/admin/release-notes#3.16.16), +[3.15.20](https://docs.github.com/enterprise-server@3.15/admin/release-notes#3.15.20), +[3.14.25](https://docs.github.com/enterprise-server@3.14/admin/release-notes#3.14.25) ++ GitLab [18.10.1, 18.9.3, 18.8.7](https://about.gitlab.com/releases/2026/03/25/patch-release-gitlab-18-10-1-released/), +[18.10](https://about.gitlab.com/releases/2026/03/19/gitlab-18-10-released/), +[18.9.2, 18.8.6, 18.7.6](https://about.gitlab.com/releases/2026/03/11/patch-release-gitlab-18-9-2-released/) ++ GitKraken [11.10.0](https://help.gitkraken.com/gitkraken-desktop/current/) ++ GitHub Desktop [3.5.6](https://desktop.github.com/release-notes/) ++ Garden [2.6.0](https://github.com/garden-rs/garden/releases/tag/v2.6.0) ++ Git Cola [4.18.2](https://github.com/git-cola/git-cola/releases/tag/v4.18.2), +[4.18.1](https://github.com/git-cola/git-cola/releases/tag/v4.18.1), +[4.18.0](https://github.com/git-cola/git-cola/releases/tag/v4.18.0) ++ GitButler [0.19.6](https://github.com/gitbutlerapp/gitbutler/releases/tag/release/0.19.6), +[0.19.5](https://github.com/gitbutlerapp/gitbutler/releases/tag/release/0.19.5) ## Credits From ecb8cce5bbda76b6ba8a551d9eafea76d11929c0 Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Sun, 29 Mar 2026 16:29:56 +0200 Subject: [PATCH 03/92] rn-133: add Olamide Caleb Bello among the helpers --- rev_news/drafts/edition-133.md | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/rev_news/drafts/edition-133.md b/rev_news/drafts/edition-133.md index 466df15aa..31d40a11b 100644 --- a/rev_news/drafts/edition-133.md +++ b/rev_news/drafts/edition-133.md @@ -207,7 +207,6 @@ As always, we welcome your thoughts and feedback!_ Gmail.

Matthias asked the +list whether this was a known issue and whether it could be an attack +vector. + +To understand why this happens, it helps to know how `git-am` parses +its input. When processing a patch email, it must split the stream into +two parts: the commit message and the actual patch to apply. It does +this by treating the first occurrence of any of the following lines as +the boundary between the two: + +- a line consisting of only three dashes (`---`), +- a line beginning with `diff -`, or +- a line beginning with `Index: `. + +Everything before that boundary becomes the commit message; everything +after is fed to the patch application machinery. Crucially, `git-am` +scans from the top of the email, so the very first such line it +encounters terminates the commit message regardless of whether that +line was meant to be part of the message text. + +This design dates back to the tool's origins. As Jeff King (also known +as "Peff") quickly explained in reply to Matthias, `git-am` was +originally designed to handle patches sent by all kinds of people, not +just Git users. A contributor might have generated a diff with plain +GNU `diff` and typed the rest of the email by hand, without any `---` +separator. The tool was therefore intentionally permissive: it would +find a `diff -` line anywhere in the email and treat it as the start +of the patch. Peff demonstrated this with a live example. He fed `git +am` a hand-typed email containing a GNU diff, and it produced the +expected commit. + +This historical context also explained why `git-am` is notoriously +hard to fix: "I don't think there is a way to unambiguously parse the +single-stream output that format-patch produces," Peff wrote, noting +that he could find at least three earlier discussions of the same +problem (in 2015, 2022, and 2024). The stream is simply ambiguous by +design. Even the `---` marker itself cannot be used to robustly split +things, since `---` on a line by itself is a valid diff hunk line +indicating that the string `--` was removed from a file. + +Matthias proposed parsing from the end of the email rather than from +the top. Peff replied that this would still be ambiguous for the same +reasons, and would introduce new corner cases. + +Jacob Keller noted early on that the issue was certainly surprising but +that he was unsure it constituted a security attack vector, since +someone should be reading the commit message before applying. But +Matthias pushed back: the whole point was that nobody realized the +behavior was there. He called it "sheer luck" that it was only a +`sleep(1)` and not something more malicious crafted as a diff in the +commit message. + +Florian Weimer wondered whether the `git-format-patch` output was +really ambiguous, given that the patch section is normally preceded by +a diffstat block. Peff replied that the diffstat is optional and is not +even parsed by the receiving side at all. + +Jakob Haufe added an important nuance: even if `git-am` were fixed to +require indented diffs, it would only partially mitigate the problem, +because `patch(1)` (which many distributions use to apply upstream +fixes to packages) is even more permissive. It will strip a consistent +level of indentation from diffs before applying them. He quoted the +`patch(1)` manual page: "If the entire diff is indented by a +consistent amount, [...] this is taken into account." The i3 incident +had in fact been triggered by `patch(1)`, not `git-am`. + +Kristoffer Haugsbakk synthesized this into a clear summary of the +situation and immediately proposed documenting it. + +Matthias also highlighted the broader applicability beyond email +workflows: Linux distributions like NixOS routinely fetch patches +directly from upstream Git repositories and apply them to packages +using `patch(1)`. He noted that even after 15 years of using Git and +being comfortable with email patch workflows, he himself had not known +about this behavior. + +Several directions were then explored to look for solutions. + +Peff observed the irony that `git-format-patch` does have a `--attach` +option which puts the message and the patch in separate MIME parts — +making them unambiguous in principle. However, `git-mailinfo` (which +powers `git-am` under the hood) decodes both parts into a single +stream and still treats a `diff` line in the message part as the start +of a patch. Fixing this would require careful surgery to avoid +breaking the existing forgiving handling of patches received as a +single attachment. + +Patrick Steinhardt suggested that even if parsing cannot be made +unambiguous, `git-am` could at least detect the ambiguity and bail by +default with an `--accept-ambiguous-patch` override. Jacob Keller +proposed going further: a new "unambiguous mode" where +`git-format-patch` would produce output that new versions of `git-am` +could distinguish unambiguously, while old versions would still handle +the common case the same way as before. + +Jacob had also sketched a concrete scheme: add a new unambiguous +marker after the `---` separator, so that old versions of `git-am` +would still cut at the `---` and ignore everything up to the diff, while +new versions would wait for the new marker and correctly ignore any +diff appearing before it. Since the new marker would come after `---`, +it would not be inserted into the commit message when applied. + +Peff replied that this was trickier than it sounded: the new marker +would have to be something that could never appear legitimately in a +commit message, and both sides would need to complain if they saw +multiple markers. He explored further options: reversible quoting of +`---` and `diff` lines in the commit message (analogous to the `>From` +quoting used in mbox files), applied only when the message would +otherwise be ambiguous. This way, if an older `git-am` received the +mail, the worst case would be visible quoting in the commit message — +ugly but readable. Junio Hamano, the Git maintainer, added another +thought: refusing to accept unsigned patches at all. + +Peff also proposed a simpler receiver-side improvement: a +`git am --strict` mode that would always require a `---` separator +before the diff, on the assumption that well-formatted patches from Git +always have one. This would not help with diffs that legitimately +appear before the `---`, but would eliminate the most common accidental +cases. + +None of these ideas led to an immediate implementation, as they all +involve backward compatibility tradeoffs that would need careful +thought. + +On February 8, Kristoffer sent a documentation patch titled "doc: add +caveat about roundtripping format-patch" which introduced a new +`Documentation/format-patch-caveats.adoc` file explaining the +behavior. The caveat was designed to be included in the documentation +for `git-am`, `git-format-patch`, and `git-send-email`. + +Junio reviewed +[version 1](https://lore.kernel.org/git/format-patch_caveats.281@msgid.xyz) +and offered a correction to the wording: rather than saying that an +unindented diff in the commit message "will not only cut the message +short but cause that very diff to be applied, along with the patch in +the patch section," Junio noted that the outcome is not so +deterministic. The diff in the commit message might get applied, or +the patch machinery might trip on something and fail outright. He also +flagged that the space after the `---` in the cover letter was +inconsistent with the project's conventions. + +Phillip Wood reviewed the patch and found the mention of +`git-send-email` a bit distracting, since that command merely runs +`git-format-patch` and does not do any formatting itself. He also +suggested wording improvements: replacing "One might want to use [...] +patch(1)" with "Given these limitations, one might be tempted to [...]". + +Kristoffer incorporated all of this in +[version 2](https://lore.kernel.org/git/V2_format-patch_caveats.34b@msgid.xyz), +which dropped the `git-send-email` mention from the introductory +paragraph (while keeping the CAVEATS section in its documentation, for +users who encounter it there), removed example code blocks in favor of +clearer prose, and used the list of message-terminating patterns +already present in `git-am`'s documentation. Junio reviewed it and +queued it with the comment "Nicely written." + +A third version, +[version 3](https://lore.kernel.org/git/pull.2220.v3.git.git.1772559813151.gitgitgadget@gmail.com), +was submitted and received Junio's approval to go to `next`. + +Meanwhile, Phillip had observed that since the parsing cannot be fixed, +"perhaps we should update our sample `commit-msg` hook to reject +messages that will cause problems." On February 7, he sent a 3-patch +series titled "commit-msg.sample: reject messages that would confuse +`git am`". The series: + +1. Added a `.gitattributes` rule for sample hooks (which are shell + scripts but have `.sample` extensions). +2. Extended the sample `commit-msg` hook to scan the body of the commit + message for unindented `diff -` and `Index: ` lines and reject the + commit with a helpful error message. +3. Added a further check to detect `---` separator lines in the message + body, which would cause `git-am` to silently truncate the commit + message. + +Peff reacted with measured skepticism to patch 3 in +[version 1](https://lore.kernel.org/git/cover.1770476279.git.phillip.wood@dunelm.org.uk): +he and Junio both pointed out that they themselves sometimes use `---` +intentionally in commit messages to add notes that will appear in the +formatted patch email but not end up in the final commit message when +applied. Junio explained the trick: "when I know what I want to write +below the three-dash lines, I would commit with `---` and additional +notes below it, so that I do not forget during format-patch. When the +commit is turned into a patch email [...] `am` cuts at the first one, +and `apply` knows that the garbage lines at front, including +three-dash lines, do not matter until it sees `^diff`, this works out +perfectly well." + +Peff confirmed he used the same trick. Phillip, acknowledging that at +least three developers relied on this behavior, decided to drop patch 3 +entirely, reducing the series from three patches to two, in +[version 2](https://lore.kernel.org/git/cover.1770993281.git.phillip.wood@dunelm.org.uk). +He also refined the diff detection in the body: the v2 correctly skips +the first paragraph of the message (which becomes the email Subject +header and so does not go through the patch boundary detection), skips +lines below a scissors line, and handles the `core.commentChar` and +`core.commentString` configuration options for determining which lines +are comments. Junio reviewed version 2 with detailed questions about +the scissors-line logic. + +Kristoffer verified that version 2 worked with `git commit +--cleanup=scissors --verbose` and was satisfied. + +The discussion did not lead to a fundamental fix to the ambiguous +parsing in `git-am`, which remains an open problem with no obvious +backward-compatible solution.

On February 7, he sent a 3-patch -series titled "commit-msg.sample: reject messages that would confuse -`git am`". The series: - -1. Added a `.gitattributes` rule for sample hooks (which are shell - scripts but have `.sample` extensions). -2. Extended the sample `commit-msg` hook to scan the body of the commit - message for unindented `diff -` and `Index: ` lines and reject the - commit with a helpful error message. -3. Added a further check to detect `---` separator lines in the message - body, which would cause git-am(1) to silently truncate the commit - message. - -Peff reacted with measured skepticism to patch 3 in -[version 1](https://lore.kernel.org/git/cover.1770476279.git.phillip.wood@dunelm.org.uk): -he and Junio both pointed out that they themselves sometimes use `---` -intentionally in commit messages to add notes that will appear in the -formatted patch email but not end up in the final commit message when -applied. Junio explained the trick: "when I know what I want to write -below the three-dash lines, I would commit with `---` and additional -notes below it, so that I do not forget during format-patch. When the -commit is turned into a patch email [...] `am` cuts at the first one, -and `apply` knows that the garbage lines at front, including -three-dash lines, do not matter until it sees `^diff`, this works out -perfectly well." - -Peff confirmed he used the same trick. Phillip, acknowledging that at -least three developers relied on this behavior, decided to drop patch 3 -entirely, reducing the series from three patches to two, in -[version 2](https://lore.kernel.org/git/cover.1770993281.git.phillip.wood@dunelm.org.uk). -He also refined the diff detection in the body: the v2 correctly skips -the first paragraph of the message (which becomes the email Subject -header and so does not go through the patch boundary detection), skips -lines below a scissors line, and handles the `core.commentChar` and -`core.commentString` configuration options for determining which lines -are comments. Junio reviewed version 2 with detailed questions about -the scissors-line logic. - -Kristoffer verified that version 2 worked with `git commit ---cleanup=scissors --verbose` and was satisfied. - -The discussion did not lead to a fundamental fix to the ambiguous -parsing in git-am(1), which remains an open problem with no obvious -backward-compatible solution. But it produced two concrete -improvements that were accepted and are now in `master`: a CAVEATS -section in the documentation for git-am(1), git-format-patch(1), and -git-send-email(1) spelling out exactly how commit messages can -inadvertently interfere with patch application, and an enhanced sample -`commit-msg` hook that rejects messages containing unindented diffs. - -The thread also served as a useful reminder that this problem is not -limited to email workflows: any project that generates patches from -Git commits using git-format-patch(1) and applies them with patch(1) -or git-am(1) is exposed to it.

The hand-rolled output + also omits the `index` lines, `new file mode` headers, and funcname + context in `@@` hunk headers that the standard pipeline produces. + + Michael Montalbo opened the discussion by sending a four-patch + series that finally addresses this long-standing limitation. The + series explicitly replaced an earlier attempt of his, + ["line-log: fix `-L` with pickaxe options"](https://lore.kernel.org/git/pull.2061.git.1772651484.gitgitgadget@gmail.com/), + which had taken the opposite approach of *rejecting* `-S`/`-G` when + combined with `-L`; the new direction is to make those options + *work* instead. Patch 1 carries over a crash fix from that previous + attempt unchanged. Patch 2 is the core change. Patch 3 adds an + extensive set of tests for the newly-working options. Patch 4 + updates the documentation. + + Patch 1 fixes a real assertion failure that could be triggered by + combining `-L` with pickaxe options across a merge that contains a + rename, an issue originally reported by Matthew Hughes. Inside + `queue_diffs()`, the caller's `diff_options` was being reused for + rename detection, which meant that any user-specified pickaxe state + (`-G`, `-S`, or `--find-object`) would run inside `diffcore_std()` + and silently discard diff pairs that the rename machinery still + needed. The fix builds a private `diff_options` for the + rename-detection path, mirroring the pattern already used in `git + blame`'s `find_rename()`, and isolates the rename machinery from + unrelated user options. + + Patch 2 is where the heavy lifting happens. Instead of formatting + output by hand, `-L` now feeds its filepairs through + `builtin_diff()` and `fn_out_consume()`, the same path used by + `git diff` and `git log -p`. The mechanism is a pair of callback + wrappers that sit between `xdi_diff_outf()` and `fn_out_consume()`, + filtering xdiff's output down to only the tracked line ranges. To + make sure xdiff actually emits every line within each tracked range + as context, the context length is inflated to span the largest + range. The tracked line ranges themselves are now carried on `struct + diff_filepair` as a borrowed pointer, so that each file's ranges + travel with its filepair through the rest of the pipeline. As a side + effect, `line_log_print()` shrinks down to little more than a + `diffcore_std()` call followed by `diff_flush()`, the + `-L`-implies-`--patch` default is wired up in revision setup rather + than forced at output time, and `diff_filepair_dup()` is switched + from `xmalloc` to `xcalloc` so that newly added fields (including + the `line_ranges`) are zero-initialized. + + Because `diffcore_std()` now actually runs at output time, options + such as `-S`, `-G`, `--orderfile`, and `--diff-filter` come along + for the ride and start working with `-L` for the first time. Michael + also notes in the commit message that the context-length inflation + means xdiff might process more output than strictly needed for very + wide ranges, but his benchmarks on files up to 7800 lines showed no + measurable regression. + + There is, of course, a user-visible output change: `-L` output now + includes `index` lines, `new file mode` headers, and funcname + context in `@@` hunk headers that were previously absent. Tools that + parse `-L` output may need to handle these additional lines. The + cover letter is upfront about this, and also lists two limitations + that are deliberately left for follow-up work: `line_log_print()` + still calls `show_log()` and `diff_flush()` directly rather than + going through `log_tree_diff_flush()`, and the non-patch diff + formats (`--raw`, `--numstat`, `--stat`, etc.) remain unimplemented + for `-L`. + + Junio Hamano, the Git maintainer, replied to the cover letter the + same day with a single word: "Exciting." He approved the deliberate + incremental scope, observing that since "previously all the output + routines were hand-rolled, but this reduces the extent of deviation + --- as long as we are moving in the right direction, it is a good + idea to find a good place to stop and leave the rest for later." On + the note about non-patch diff formats, Junio remarked that "it would + not hurt if these are omitted", which led to a small back-and-forth + where Michael initially thought he was being asked to do something + extra in a follow-up; Junio clarified that the series was already + omitting them ("You are already omitting, no? I took 'remain + unimplemented' to mean exactly that"), and that simply *mentioning* + the omission, as the cover letter already did, was the right thing + to do. + + Junio also pointed out that the "Michael Montalbo (4): ..." block in + the cover letter looked like a reflowed duplicate of the proper + commit list right below it. Michael acknowledged that as a mistake + in crafting the cover letter and offered to add a few names from + `git shortlog --no-merges -s -n line-log.[ch]` to the Cc list to + attract more reviewers. + + On the documentation patch (4/4), Kristoffer Haugsbakk caught a + subtle AsciiDoc problem: by indenting the new paragraph with tabs, + Michael had inadvertently turned the new prose into a code block. + Kristoffer recommended dropping the indentation in favour of a plain + list-continuation marker so the text would render as regular + paragraph text, "flush to the left." Michael thanked him and folded + the fix into his next iteration. + + For readers less familiar with the relevant pieces of the diff + stack, a few words of context may help. + + `git log -L` is itself a relatively unusual citizen in Git's command + zoo: most `git log` machinery walks commits and emits whatever its + configured formatters dictate, but `-L` additionally carries a set + of line ranges per file, narrowing the history to commits that touch + those ranges. Mapping that range-aware view onto the standard diff + output machinery is non-trivial because xdiff itself does not know + anything about the user's tracked ranges; it just produces a unified + diff for two blobs. The new callback wrappers introduced in patch 2 + bridge that gap by intercepting xdiff's output as it is generated + and discarding hunks that fall outside the requested ranges. + + The `diffcore_std()` function is the standard point at which Git + applies a number of cross-cutting transformations to a queued set of + diff pairs: rename detection, the pickaxe filters (`-S`, `-G`, + `--find-object`), the orderfile sort, and the `--diff-filter` + filter, among others. Once `-L` actually feeds its pairs through + this function, all of those features become available essentially + "for free." That is also why patch 1 has to be careful: rename + detection performed during the line-history walk must *not* let a + user's pickaxe filter inadvertently throw away the very pairs the + rename machinery needs to do its job. + + After the initial round of review, Michael sent + [version 2](https://lore.kernel.org/git/pull.2065.v2.git.1773714095.gitgitgadget@gmail.com) + of the series. The only structural change from v1 was that patch 4 + now uses a list-continuation marker instead of indentation in + `Documentation/line-range-options.adoc`, addressing Kristoffer's + review feedback so the new paragraph renders correctly. The + crash-fix patch (1/4) also gained an explanatory comment in its test + file about commit-level filtering with pickaxe still being a known + limitation: `show_log()` prints the commit header before + `diffcore_std()` runs, so commits cannot yet be suppressed even when + no diff pairs survive filtering. Fixing that would require deferring + `show_log()` until after `diffcore_std()`, which is again a larger + log-tree restructuring that v2 explicitly leaves for later. + + Junio reviewed v2 patch 2 again and was generally positive. He noted + that "huge diff to the test material mostly comes from the addition + of the diff headers like the index line, etc., which makes this + patch scary but is very welcome addition", and on the new field + `line_ranges` carried on `struct diff_filepair`, simply replied + "OK." On the rewrite of `line_log_print()` itself, which now queues + a duplicated filepair per range, attaches the borrowed + `line_ranges`, and calls `diffcore_std()` followed by + `diff_flush()`, he wrote: "Very welcome change." + + Some weeks later, after no further substantive review arrived, Junio + came back to the v2 cover letter and wrote, in a slightly resigned + but encouraging tone: "The central part of the series (i.e., patch + #2) looked quite sensible. I haven't read the tests very carefully, + though. I was hoping that we will see another set of eyes or two to + help review this series, but nothing has happened in the past few + weeks, so let's mark the topic for 'next'." The series was later + merged into 'master' and these improvements have been released as + part of Git v2.54.0. + + This is an example of long-standing technical debt finally being + paid down. A `NEEDSWORK` comment that has lived in `line-log.c` for + many years is finally retired; an entire family of diff options + (formatting, whitespace, pickaxe, output-indicator, prefix, + color-moved, and more) becomes available with `-L` for the first + time; and a real assertion failure involving merges, renames, and + pickaxe filters is fixed along the way. - +## Developer Spotlight: Meet Soni + +_Editor’s note: This edition features a retrospective interview with a +contributor who contributed to Git through a mentoring program. +We hope the reflections shared by the GSoC contributor will +provide an insightful perspective that benefits the community. +As always, we welcome your thoughts and feedback!_ + +* **Who are you and what do you do?** + + I'm Meet, a final-year Computer Engineering student from Ahmedabad, India. I've + done GSoC twice - first with the Python Software Foundation [working on `cve-bin-tool`](https://summerofcode.withgoogle.com/archive/2024/projects/aEIXRpxg), + and then with Git [working on the git-refs command](https://summerofcode.withgoogle.com/archive/2025/projects/xVrT5e2q). + I also did an LFX Mentorship with Microcks under CNCF between the two GSoCs. + Currently I'm doing an internship at an early-stage stealth startup alongside + finishing up my degree. + +* **How did you initially become interested in contributing to Git, and what + motivated you to choose it as your GSoC project?** + + Back in 2021, a friend showed me a video about GSoC and it seemed completely + out of reach at the time. Fast forward to late 2023, the same friend suggested + we finally give it a real shot. We both spent about 4 months contributing to + open-source projects to build up experience. Both of us got selected for GSoC + 2024. I got into the Python Software Foundation. After finishing GSoC with PSF, + I loved the experience so much that I wanted to do it again. I decided to try + Git for GSoC 2025. I started by sending some small patches to get familiar with + the codebase and the mailing list workflow, reviewed patches from other + prospective GSoC students, and eventually proposed the git-refs consolidation + project. + +* **Is there any aspect of Git that you now see differently after having + contributed to it?** + + Before contributing, I only really knew about Git's porcelain commands - `push`, + `pull`, `fetch`, `rebase`, `checkout`, the stuff you use every day. I had no + idea how much was happening underneath. Once I started reading the Git Internals + chapters from the [Pro Git book](https://git-scm.com/book/en/v2) and diving into + the source code, I discovered this whole world of plumbing commands - + `cat-file`, `hash-object`, `update-index`, `for-each-ref`, `update-ref`, `rev-parse`, + `ls-tree`, `write-tree` - there are way more of them than the porcelain + commands most people interact with. + + I learned that Git is fundamentally a content-addressable filesystem with a + VCS interface built on top. Everything is an object - blobs hold file + contents, trees represent directories, commits are snapshots pointing to + trees, and refs are just pointers into this object graph. The objects are + addressed by their SHA-1 hashes, and everything you do through the familiar + commands is just a thin layer operating on this object database. Understanding + all of this completely changed how I think about version control. When + something goes wrong in Git, I no longer feel lost - I can reason about what's + actually happening at the object level. + + +* **How do you balance your contributions with other responsibilities like work + or school?** + + During GSoC, I was mostly focused on Git full-time. My university schedule was + flexible enough that I could dedicate most of my working hours to the project. + That said, there were stretches where college reviews and submissions piled up + at the same time as a patch series needed revisions, and that got a little + hectic. I ended up working on weekends sometimes to make up for lost time and + stay on track with the project timeline. The trickier part was the mailing list + workflow itself - reviews could come at any time given the global nature of the + community, so I had to stay responsive even during busy college weeks. + +* **Can you share how GSoC helped enhance your technical and non-technical skills + (like communication, project management, etc.)?** + + On the technical side, working on Git taught me a lot about writing C code that + has to be clean enough for others to maintain long after you're gone. The Git + codebase has strict coding standards and the review process enforces them. I + got much better at designing modular code, writing meaningful commit messages, + and structuring patch series so that each patch tells a clear story. + + On the non-technical side, the mailing list workflow was probably the biggest + growth area. All communication is public, asynchronous, and text-based. There's + no hiding behind a quick Slack message - you have to articulate your design + decisions clearly in writing. I also learned how to take feedback without + taking it personally. Early on, getting a review that asked me to rethink my + approach felt discouraging. Over time I realized that the reviewers were + investing their time in making my code better, and that changed my perspective + entirely. + +* **What was your biggest takeaway or learning from GSoC that you now apply + regularly in your work?** + + Community consensus matters more than being technically correct. In Git, you + can write perfectly functional code, but if the community doesn't agree with + the design direction, it won't get merged. My project depended heavily on + consensus around how the git-refs command should behave and what it should + consolidate. I spent a fair amount of time not just writing code, but defending + design choices and sometimes accepting that a different approach was better [ [patch series](https://lore.kernel.org/git/20250627074934.1761897-1-meetsoni3017@gmail.com/) ]. + That taught me to separate my ego from my code. I try to apply that everywhere + now - when someone pushes back on something I wrote, my first reaction is to + understand why, not to defend. + +* **What was the biggest challenge you faced during your contributions to Git, + and how did you overcome it?** + + The mailing list workflow. Before Git, all of my open-source contributions were + made on GitHub through pull requests. Git uses email-based patches, which was a + completely different process - formatting patches with `git send-email`, making + sure the threading is correct, handling version updates to a patch series. The + first few times I felt like I was fighting the tooling more than the actual + code. + + But it got easier. After a few rounds, it started to feel like second nature. + The bigger challenge was the review process itself. Git's mailing list reviews + are thorough. Reviewers will question your variable naming, your commit message + wording, your design rationale - everything. Having to defend code changes and + push features to near-perfection was time consuming, but it made me a much + better programmer. I overcame it by just sticking with it and treating every + review comment as a learning opportunity rather than criticism. + +* **Have you thought about mentoring new GSoC / Outreachy students?** + + Yes, I'd love to. After my GSoC 2024 with PSF, a lot of students reached out to + me for guidance on open source and GSoC applications. I helped several of them + with finding the right organizations, reviewing proposals, and getting started + with contributions. Three of them got selected for GSoC 2025, which I'm really + proud of. + + For Git specifically, I'd like to mentor in the future, but I want to be in a + position where I can give it the time it deserves. Right now I'm occupied with + finishing my degree, an internship at a startup, and job hunting, so it + wouldn't be fair to a mentee if I signed up and couldn't be fully present. But + it's definitely something I want to do - the mentorship I received from Patrick + Steinhardt and Jialuo She was really valuable, and I'd like to pay that + forward. + +* **What upcoming features or changes in Git are you particularly excited about?** + + The introduction of Rust into the Git codebase. Git 2.52 was the first release + to optionally include Rust code, starting with variable-width integer encoding. + Rust will become mandatory for [Git 3.0](https://git-scm.com/docs/BreakingChanges). + As someone who's written C code for Git, I find this really interesting - Rust + brings memory safety guarantees that could prevent entire classes of bugs. + +* **What is your toolbox for interacting with the mailing list and for + development of Git?** + + For writing code, I use [AstroNvim](https://astronvim.com/) as my editor. For + sending patches, I use [`git send-email` configured](https://git-send-email.io/) + with Gmail's SMTP. For reading and replying to mailing list threads, I just + use Gmail's web interface + - it works well enough for following discussions and replying inline. I + develop and test on Linux, which I've been using as my daily driver since + 2020. + +* **What is your advice for people who want to start Git development? Where and + how should they start?** + + Read the [Pro Git book](https://git-scm.com/book/en/v2) first, especially the + Git Internals chapters. It gives you a mental model of how Git actually works + underneath, which makes reading the source code much less intimidating. + + Then, start small. Subscribe to [the mailing list](https://git-scm.com/community#git-mailing-list) + and just read for a week or two. Look at what kind of patches are being sent, + how reviews work, how people structure their patch series. The Git project has + a document called "[MyFirstContribution](https://git-scm.com/docs/MyFirstContribution)" + in the Documentation folder that walks you through the entire process of + submitting your first patch. + + For your first contribution, look for something small - a documentation fix, a + test improvement, a minor bug fix. The goal isn't to make a big impact right + away. The goal is to get comfortable with the workflow: formatting patches, + sending them via email, responding to reviews. Once you've done that once or + twice, everything else gets easier. + + And don't be afraid of the mailing list. It looks intimidating from the + outside, but the community is genuinely helpful. Reviewers invest real time + into helping newcomers improve their patches. Take that feedback seriously and + you'll grow fast. + +* **Would you recommend other students or contributors to participate in the + GSoC, Outreachy or other mentoring programs, working on Git? Why? Do you have + advice for them?** + + Absolutely. GSoC with Git was one of the best experiences I've had. The + community is welcoming, the mentors are invested in your success, and the + codebase is one of the most widely used pieces of software in the world. + There's something special about knowing that the code you wrote is running on + millions of machines. + + My advice: start contributing early, well before the application period. Don't + just pick Git because it looks good on a resume - pick it because you're + genuinely curious about how it works. The people reviewing your patches can + tell the difference. Also, get comfortable with the mailing list workflow + before GSoC starts. It's the single biggest adjustment for most newcomers, and + if you spend your GSoC period still figuring out `git send-email`, you'll lose + valuable time. + + And finally, be patient with yourself. The Git codebase is large and the + standards are high. Your first patches will probably need multiple revisions. + That's normal. Every contributor who came before you went through the same + thing. ## Other News From a49d0ee3f0e119547e641a27f6934f34d3dea418 Mon Sep 17 00:00:00 2001 From: Kaartic Sivaraam Date: Fri, 1 May 2026 23:40:55 +0530 Subject: [PATCH 28/92] rn-134: fix a small formatting issue in interview --- rev_news/drafts/edition-134.md | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/rev_news/drafts/edition-134.md b/rev_news/drafts/edition-134.md index 1d9ec1853..dd274a6a5 100644 --- a/rev_news/drafts/edition-134.md +++ b/rev_news/drafts/edition-134.md @@ -355,10 +355,8 @@ As always, we welcome your thoughts and feedback!_ For writing code, I use [AstroNvim](https://astronvim.com/) as my editor.

He pointed out that, if so, this would cause "substantial + problems" in setups where libgit2 or JGit is used interchangeably + with Git, when users need to downgrade Git, or when several Git + versions live side by side on the same system, for instance through + GitHub Desktop, which bundles its own copy of Git. + + The multi-pack-index (MIDX) is an on-disk file at + `.git/objects/pack/multi-pack-index` (and possibly chained files) + that indexes objects across several pack files at once. It is meant + to be a purely optional acceleration layer: when present and + readable, lookups can avoid scanning each pack's own `.idx` index + file; when absent or unreadable, Git is supposed to fall back to the + underlying `.idx` files. Several high-impact features (auto + maintenance, `git multi-pack-index`, reachability bitmaps, geometric + repack, etc.) build on top of it, and modern Git distributions + write or update it as part of routine operations, including the + maintenance step that runs after a `git fetch`. + + The "version 2 not recognized" error came from `b2ec8e90c2` (`midx: + do not require packs to be sorted in lexicographic order`, + 2026-02-24). That commit relaxed an internal ordering constraint + and, because the relaxation makes the on-disk file unreadable by + other tools that still expect the older invariant, guarded the new + behaviour behind a bump in the MIDX on-disk format version (from v1 + to v2). The commit message explicitly justified the bump by claiming + that "older versions of Git know how to gracefully degrade and + ignore any MIDX(s) they consider corrupt". As the discussion would + reveal, this assumption turned out to be too optimistic. + + Junio Hamano, the Git maintainer, picked up the thread and pointed + directly at `b2ec8e90c2` as the likely culprit. Reading the commit + message back to itself, he observed that the format-version bump + "seems to be doing more harm to 'older versions of Git' that 'know + how to gracefully degrade' by not allowing them to degrade", and he + asked Taylor Blau (the author of the MIDX v2 work and the area's + principal maintainer) whether the release notes should at least + carry recovery instructions, such as `rm -f .git/objects/pack/*.midx`. + + Jeff King, alias Peff, replied within hours with a deeper + diagnosis. The MIDX *should* be optional, he wrote. If loading the + file returns an error, callers should silently fall back to the + regular `.idx` files, but that property is not actually held by the + load path, which contains a few `die()` calls instead. He + demonstrated by applying a small patch on top of v2.53.0 that + replaces the two relevant `die()` calls in + `load_multi_pack_index_one()` (one for the signature mismatch, one + for the unknown version) with `error()` plus a `goto cleanup_fail`, + producing the desired behaviour: the user sees `version 2 not + recognized` printed once and then everything works anyway. "But of + course we can't go back in time now to fix it (and earlier + versions)", he noted. + + Peff also surveyed the third-party implementations Dscho had worried + about: + + - JGit, on inspection of its source, throws an exception that is + apparently caught and handled correctly (he verified with the + `jgit` CLI on hand). + - libgit2 returns from a helper called `midx_error()` when the + signature or version do not match. Reading the code, Peff + believed it would quietly fall back to the underlying packs. + + His conclusion: "it really is just our old versions that are the + problem". + + He then asked the natural follow-up question: how hard would it be + to revert the default written MIDX version back to v1? In a second + message a few minutes later he answered himself with a + near-one-liner in `midx-write.c` changing the default initializer of + `write_midx_context.version` from `MIDX_VERSION_V2` to + `MIDX_VERSION_V1`, plus minor adjustments to the test suite: in + `t/t5319-multi-pack-index.sh`, the expected header would once again + say "header: ... 1 ..." rather than "header: ... 2 ..."; and in + `t/t5335-compact-multi-pack-index.sh`, since MIDX compaction + *requires* the v2 format, the test would now opt back into v2 + explicitly via `git config --global midx.version 2`. Peff observed + that an existing `midx.version` config knob lets users opt into v2 + manually, and he left the strategic decision to Taylor. + + Derrick Stolee underlined the part of Dscho's report that he + considered most striking: the bad file is written automatically as + part of normal maintenance after a fetch, so removing the broken + MIDX by hand "will not keep the repo in a good state". The next + fetch will simply regenerate it. He agreed that a graceful fallback + (with a visible warning) belongs in Git too, and that the immediate + fix should be to stop writing v2 by default so that a 2.53/2.54 + mixed deployment stops poisoning the repository at every fetch. + + Junio, after asking Derrick to clarify the "good state" sentence (he + initially read it as "the MIDX is no longer optional"), eventually + agreed: defaulting back to v1 *and* leaving the more thorough + graceful-degradation work for later was the right split for the + remaining rc window. In a later round of the same sub-thread, + Derrick clarified that what he had meant was that the deletion was + not a *durable* fix on its own. The maintenance step would keep + regenerating the v2 file unless the default version was also lowered + (or `midx.version` set to `1`). + + Taylor Blau then weighed in, apologetic about the "trouble here", and + laid out a clean three-step plan for the project: + + 1. **Immediate (before 2.54)**: revert the default MIDX format to + V1, so a 2.54.0 release does not regress the case where multiple + Git versions are used against the same repository. + 2. **Medium term (after 2.54)**: implement the graceful-degradation + idea Peff sketched in `load_multi_pack_index_one()`, so that + unknown versions cause Git to ignore the MIDX instead of dying. + This won't help current 2.53 and earlier users, but it would + make a future flip from V1 to V2 by default truly painless from + 2.55 onward. + 3. **Long term (2.56 or later)**: make V2 the default once enough + versions in the field can already cope with it. + + Peff acknowledged the plan, only adding a caveat: two releases may + be "not very long, especially for people who are using OS packages", + e.g. people moving across Debian stable releases. But that could be + sorted out later. + + To make sure something concrete was in the rc, Junio took Peff's + near-one-liner, polished the commit message, and proposed + [a first version](https://lore.kernel.org/git/xmqq8qam217m.fsf_-_@gitster.g) + titled "MIDX: keep the default version to MIDX v1" (later renamed + "MIDX: revert the default version to v1"). The patch simply + initialised `write_midx_context.version` to `MIDX_VERSION_V1`, fixed + up the expected on-disk header in `t/t5319-multi-pack-index.sh`, and + opted `t/t5335-compact-multi-pack-index.sh` into V2 explicitly via + `git config --global midx.version 2` so the compaction tests + continued to exercise the new format. + + In parallel, Junio also floated + [a second patch](https://lore.kernel.org/git/xmqqh5pa22h0.fsf@gitster.g) + that would have weakened the two `die()` calls in + `load_multi_pack_index_one()` to `error()` + `goto cleanup_fail`, + implementing Peff's earlier suggestion. He himself was unsure about + that one, though, observing that doing so during the rc period would + effectively promise that the MIDX is forever an optional component, + and that the error messages should at least be reworded to make + clear that they mean "we are ignoring this corrupt file" rather than + "this is a fatal corruption". After a follow-up exchange with Peff + about how dense the rest of `load_multi_pack_index_one()` is with + `die()` calls (Peff confessed he had not actually looked past the + two lines he had touched, and Junio confessed he had not either + until he had to reply), they agreed that the right fix is *at the + caller side*. The loader function genuinely is reporting "this MIDX + is broken", and it is the caller's responsibility to decide whether + to continue without it. The reword-and-soften idea was put aside as + "an issue for much later". + + Peff replied to Junio's first patch with a small but elegant + counter-proposal: rather than defaulting to V1 *always* (which would + force users of the new `git multi-pack-index compact` feature to set + `midx.version=2` manually), make `write_midx_internal()` pick V1 by + default but switch to V2 automatically when the caller has set the + `MIDX_WRITE_COMPACT` flag. Concretely, in + [his refined version of the patch](https://lore.kernel.org/git/20260416200659.GB1887222@coredump.intra.peff.net), + he removed the V2 initialiser from the `write_midx_context` + declaration, and inserted the following just below, and just above + the existing + `repo_config_get_int(ctx.repo, "midx.version", &ctx.version)` + lookup that lets a user override the choice: + + ``` + ctx.version = opts->flags & MIDX_WRITE_COMPACT ? + MIDX_VERSION_V2 : + MIDX_VERSION_V1; + ``` + + The companion documentation update in + `Documentation/git-multi-pack-index.adoc` adds a single sentence to + the `compact::` description noting that compaction "requires writing + a version-2 midx that cannot be read by versions of Git prior to + v2.54", and the only test fallout is in + `t/t5319-multi-pack-index.sh`, where the expected header version + flips back from `2` to `1`. Notably, + `t/t5335-compact-multi-pack-index.sh` needs no change. Compaction + continues to "just work" because the new auto-select picks V2 for + it. + + Peff also confessed there are probably some gaps in V2 testing in + `t5319` left behind by this flip (the bulk of those tests now + exercise V1 again), but argued that filling them in could be done + post-release. + + Junio said he had already merged the original "revert" version into + his `jch` and `next` integration branches, but had not pushed `next` + out for external testing yet, so he chucked the original and applied + this version instead, agreeing that "compact is the only thing that + needs v2" was a better workaround. + + The only remaining nit was stylistic: Junio preferred writing the + ternary as + + ``` + ctx.version = ((opts->flags & MIDX_WRITE_COMPACT) + ? MIDX_VERSION_V2 + : MIDX_VERSION_V1); + ``` + + so that the extra parentheses make the precedence of `&` vs `?:` + obvious, and so that a multi-line ternary is easier to spot when `?` + and `:` are aligned at the start of the line. Peff replied that he + liked keeping the `?` at the end of the first line, because then it + is clear from the first line alone that it is a conditional rather + than a direct assignment, but said he did not strongly care and that + Junio could mark it up while applying. By the time Peff fetched + `next` to send that reply, Junio had already done exactly that. + + Taylor reviewed Peff's refined patch in parallel: he acked the + short- and medium-term plan ("sorry again for the mess here"), + suggested a small wording tweak ("Git 2.53 and earlier" rather than + "Git 2.53" in the log message), and noted that he found the + "auto-select V2 only when the feature requires it" behaviour a + little "magical", though "less magical and more 'do the sensible + thing by default'" once you remember that anyone running compaction + already knows the trade-offs. Peff agreed about the wording but + noted that the patch had already been pushed to `next`. They also + exchanged a short note about extending the V2-specific coverage in + `t5319` going forward, which Peff suggested Taylor could pick up + post-2.54. + + The next day, Junio + [announced an update to `master`](https://lore.kernel.org/git/xmqq5x5py5ql.fsf@gitster.g), + containing Peff's "MIDX: revert the default version to v1", along + with a batch of documentation typo and grammar fixes from Elijah + Newren and a CodeQL CI bump from Dscho. He also announced that 2.54 + final would be tagged on Monday, April 20th, and that he would be + offline for a week or two afterwards.

As Elijah put it, he "decided to fix up git grep + similarly while at it". The series also corrected a small + documentation typo he had noticed in `patch-ids.h` (a missing + trailing parenthesis in a comment), as a preparatory fixup. + + For readers unfamiliar with the trade-off, partial clones let users + avoid downloading blobs upfront, at the expense of needing to + download them later as they run other commands. That trade-off can + sometimes be more painful than expected: when the needed blobs are + discovered one at a time as they are accessed, each one triggers a + separate network round-trip. Some commands like `checkout`, `diff`, + and `merge` already mitigate this by doing batch prefetches of the + blobs they will need, which dramatically reduces the cost of + on-demand loading. The aim of this series was to extend that ability + to two more commands, `git cherry` and `git grep`. + + The interesting part for `git cherry` is how to figure out, + *without* fetching anything yet, which blobs will eventually be + needed. As Elijah explained, `git cherry` works in two phases: it + first computes header-only patch IDs (based on file paths and + modes), and only falls back to full content-based IDs when the + header-only IDs collide. Those full IDs are what require reading + blob content, and the comparison is driven by a hashmap whose + comparison function, `patch_id_neq()`, is exactly what triggers the + on-demand fetches. To enumerate the colliding blobs ahead of time, + the patch temporarily swaps the hashmap's comparison function for a + trivial `always_match()` function, walks the entries that would + collide to collect their blob OIDs into an `oidset`, restores the + original comparison function, and then fetches everything in a + single batch via `promisor_remote_get_direct()`. A helper, + `collect_diff_blob_oids()`, lists the blob OIDs touched by a + commit's diff. It leaves out files that are explicitly marked as + binary in the userdiff configuration, because for those files + patch-ID just hashes the OID with `oid_to_hex()` instead of + reading the blob, so there is no point downloading it. + + While git cherry relies on hashmap comparisons, the `git grep` patch + takes an analogous but simpler approach: it adds a preliminary walk + over the tree (similar to `grep_tree()`) that collects the blobs of + interest and prefetches them in one go. + + Junio Hamano, the Git maintainer, took a first look and immediately + spotted something that did not belong: the series added a 210-line + `investigations/cherry-prefetch-design-spec.md` file to the + project. He pointed out that, as a document describing how + `git cherry` works, "it is vastly lacking", that much of its content + is the sort of material that would normally go in a commit message, + and that he was "not sure how others would benefit from being able + to read it" once the series landed. Elijah's reply was short and to + the point: "Ugh, no, sorry." That stray file had been committed by + mistake. + + Elijah quickly sent [version 2](https://lore.kernel.org/git/pull.2089.v2.git.1776472347.gitgitgadget@gmail.com), + whose only change compared to v1 was to remove that stray file, + noting it was "So embarrassing that I didn't catch that before + submitting." + + Phillip Wood reviewed v2 and made an interesting connection: + `git rebase` without `--reapply-cherry-picks` suffers from the same + problem, since it does the equivalent of `git log --cherry-pick`. He + asked whether `prefetch_cherry_blobs()` could be shared with the + cherry-pick detection in `revision.c`. Elijah agreed the connection + was correct, explaining that `git rebase` (without + `--reapply-cherry-picks`) and `git log --cherry-pick` both go + through `cherry_pick_list()` in `revision.c`, which has the same + shape as the loop in `cmd_cherry()` and triggers fetches from the + same `patch_id_neq()` callback. He even sketched what sharing the + code would look like. + + However, he preferred to leave that out of the current series, + expressing reservations about expanding partial-clone support + further into this area: `git cherry`, `git log --cherry-pick`, and + the default cherry-pick detection in `git rebase` all exist to + answer "has this patch already landed upstream?", a question that, + in repositories large enough to need partial clones, he felt "is + rarely worth the cost of computing patch-ids across arbitrary + amounts of history." His honest guidance for users on a large + repository would be to pass `--reapply-cherry-picks` (with rebase) + and skip the detection entirely, or to narrow the range under + consideration. He noted that the omission of a + `--no-reapply-cherry-picks` option in `git replay` had been a + deliberate choice rather than an oversight. He had only implemented + the `git cherry` fix because of a specific customer whose tooling + had already baked in the operation, and prefetching at least made + the worst case tolerable. He added that he would happily review a + patch from anyone wanting to carry the shared code forward. + + Phillip continued the exchange with several good questions, asking + whether patch IDs are computed for every upstream commit or just the + ones modifying the same paths, and remarking that it "is a shame + that we don't have a config setting for `--reapply-cherry-picks` as + it is easy to forget to pass that option" (a setting made awkward + because the apply backend does not support that option). He was also + "a bit surprised customers aren't complaining about tools that use + `git rebase` being slow." + + Elijah replied that determining which upstream commits modify the + same paths still requires walking the upstream commits and doing a + tree-diff for each, and that in the biggest repositories "even a + merge-base operation can start to feel expensive." On the surprise + about rebase, he answered "Are you sure they aren't complaining?", + explaining that the merging parts of a rebase already do batch + prefetching, but the cherry-pick-detection part does not. He also + noted that the customer in question was using `git replay` rather + than `git rebase`, probably because early versions of `git replay` + lacked the drop-commits-that-become-empty logic that Phillip later + added (he thanked Phillip again for that), and that the prefetch + patch lets things stay fast even if they keep their `git cherry` + calls. + + Derrick Stolee then reviewed v2, reading both the `git cherry` and + `git grep` patches together. He worried that + `collect_diff_blob_oids()` being "hidden in builtin/log.c may not be + the right long-term home", anticipating more and more cases where + Git would want to prefetch blobs, and wondered whether the logic + could take advantage of, or live alongside, the existing + `diff_queued_diff_prefetch()` within `diffcore_std()` in + `diff.c`. He framed the `git cherry` patch as caring about a diff + and the `git grep` patch as caring about a "scan prep", suggesting + `git archive` as a closer analog for the latter than `checkout`. He + was careful to add that he did not mean to complicate the series and + was "most interested in having this logic be more reusable in the + future without needing to move code across files." + + Junio, seeing that Stolee's two review messages had gone unanswered + for a while, asked whether he should keep the patches in his tree + "hoping that responses may come some day", and said he would mark + the topic as expecting review responses in the draft "What's + cooking" report for the time being. Elijah apologized for the delay, + explaining he had been pulled into firefighting and remediation + duties after a number of incidents at work, and suggested marking + the series as expecting a re-roll since Stolee had asked for an + additional test. + + Elijah then answered Stolee's reusability question in detail. He + read the patch differently: `collect_diff_blob_oids()` already leans + on the diff library at the per-commit level (`diff_tree_oid()` plus + `diffcore_std()`), and the real value of the series lives *above* + the diff library, in the accumulation across many commits. + + Concretely, the motivating case was a patch touching a few files + where upstream had tens of thousands of commits in the relevant + range, several hundred of which modified the same set of files: a + per-diff prefetch like `diff.c` uses would turn that into hundreds + of small fetches, "what this series gives you is one fetch." He + pointed out two further `git cherry`-specific filters that he felt + did not belong in the diff library: most commits are skipped before + patch-ID is even computed (so prefetching for them would be wasted), + and content for binary files is skipped because patch-ID uses + `oid_to_hex()` for them. To check Stolee's idea concretely, he + reviewed all of the existing `promisor_remote_get_direct()` call + sites and concluded that none of them shared the "diff two trees and + harvest OIDs" shape, so there was no natural shared layer above the + `promisor_remote_get_direct()` primitive itself. He agreed + `git archive` would be the closest analog if it ever grew prefetch + logic, and proposed factoring out a tree-walk helper only when a + second caller actually wanted one. + + For the `git grep` patch, Stolee asked for a test that exercises a + pathspec filter, with files like `matches.txt`, `nomatch.txt`, and + `matches.md`, so that `git grep -c "needle" HEAD -- *.txt` would + download only the matching subset. This turned out to be more + valuable than a simple test improvement: Elijah replied "Yes, + absolutely", and discovered that while he was handling pathspecs + correctly, he was unconditionally requesting whatever objects + matched the pathspecs even when those blobs were already present + locally. He promised to send a fix along with the updated test. + + That fix arrived in [version 3](https://lore.kernel.org/git/pull.2089.v3.git.1778775928.gitgitgadget@gmail.com), + which made three changes compared to v2: + + - the final patch's test case was updated, as Stolee had suggested, + to exercise a pathspec, + + - the last two patches were modified to avoid re-downloading blobs + already present locally (checking with + `odb_read_object_info_extended()` and `OBJECT_INFO_FOR_PREFETCH` + on the `git cherry` side, and `odb_has_object()` on the `git grep` + side), with the tests adjusted to verify it, and + + - a new first patch was inserted documenting the filtering contract + of `promisor_remote_get_direct()`. + + That documentation patch explains that the function does not filter + out OIDs already present locally on its happy path, so callers are + responsible for filtering and deduplicating themselves. Elijah + candidly noted in the commit message that he "missed this originally + and wrote two problematic callers". He also mentioned that he had + not pursued Stolee's code-sharing suggestion, since it appeared to + be based on a misunderstanding that the `git cherry` patch was about + a diff. + + Stolee reviewed v3 and declared it "good to go", graciously adding + that Elijah's detailed responses in the v2 thread "helped me + understand that my thought was misguided" and gave him "extra + confidence" in the approach. Junio agreed the series was "in a good + shape" and marked the topic for the `next` branch. Elijah thanked + Stolee one more time, noting that the comments on the `git grep` + patch in particular "led me to what would have been a rather + annoying bug", so calling out the test improvement had been time + well spent. + + In the end, the series was merged into the `master` branch and is part + of the recent v2.55.0 release. A concrete customer pain point led to + extending Git's existing batch-prefetching habit to two more + commands, `git cherry` and `git grep`, as well as a bug fix and + improved documentation.

Ben Knoble reported what he described as "a serious performance +bug": `git diff --no-ext-diff --quiet` ran about 10 times slower in a +secondary worktree than in the main worktree. He came prepared, with a +reproduction recipe using `git worktree add --detach` on Git's own +repository and `hyperfine` timings showing 3.4ms in the main worktree +against 223.3ms in the linked one. He noted that `--no-ext-diff` and +`--quiet` were probably red herrings, since plain `git diff` was +affected too, while `--cached` was not. He had seen the same thing at +work, where a large repository took about 6ms in one case and about +650ms in the other, and he had noticed it because his Bash prompt runs +`git diff --no-ext-diff --quiet`, making the prompt sluggish in +worktrees. + +Ben had also gathered profiling data. `perf report` showed the fast +case spending most of its time in `preload_thread()`, +`threaded_has_symlink_leading_path()` and `lstat_cache()`, while the +slow case spent much more time in `ie_match_stat()`, +`ce_modified_check_fs()`, `ce_compare_data()` and `index_fd()`. `perf +stat` showed the slow case executing roughly 150 times as many +instructions, 3.8 billion against 23 million. He asked whether the +problem was already known and how he could help narrow it down, and +mentioned he had reproduced it as far back as v2.50.0. + +### Racy Git, in brief + +To understand where this went, it helps to know how Git decides +whether a working tree file has been modified. Rather than reading and +hashing every file, Git stores the result of `lstat(2)` for each path +in the index (size, mtime, inode and so on) and compares that cached +stat information against a fresh `lstat(2)`. If they match, the file +is assumed unchanged and its contents are never read. This is what +makes `git diff` and `git status` fast. + +The problem, described in `Documentation/technical/racy-git.adoc`, is +that a file can be modified so quickly after being recorded that its +mtime does not change, leaving the cached stat information matching a +file whose contents differ. Git guards against this by treating any +index entry whose mtime is not strictly older than the index file's +own mtime as "racily clean", and falling back to reading and hashing +the contents of those entries. That fallback is exactly the expensive +path Ben's profile was showing. + +### One second of bad luck + +Jeff King replied to Ben the same evening with a surprise: on his +machine the effect was *reversed*, with the worktree being 9.43 times +**faster** than the original clone of linux.git. Comparing profiles +with `perf diff` showed the slow side spending its time computing +SHA-1s, which implied stat-dirty entries, and running +`git -C linux update-index --refresh` made both cases take about +20ms. Peff's diagnosis was that this was a racy Git problem: many +files are written in the same second as the index, so they share its +mtime and Git must err on the side of checking their contents. "So it +is not really about worktrees at all, but just 'bad luck' in +generating that initial index (that goes away next time you actually +make an index update that rewrites the whole thing)." He suggested Ben +try building with `USE_NSEC`, betting it would make the problem +disappear entirely. He also gently pointed out that `git shortlog -ns` +is nicer than the pipeline Ben had used to find likely reviewers. + +Ben confirmed that `update-index --refresh` fixed his timings too, and +wondered whether `git diff` should refresh the index itself, or +whether creating a worktree should do the equivalent. He also noticed +that the Meson build automatically sets `USE_ST_TIMESPEC` or `NO_NSEC` +but offers no way to turn on `USE_NSEC`, and offered to write that +patch. + +Peff replied that `git diff` *does* refresh the index internally, +"that's what takes so long!", and that he had expected the result to +be written back out. He also explained why refreshing right after `git +worktree add` would not help: the trouble is that the index has just +been written, so it *should* be entirely up to date, but some entries +share its timestamp. What makes an explicit `update-index --refresh` +work is simply that a second has elapsed in between. Run automatically +from the worktree command, it might all still happen within the same +second. And, he noted, this is not specific to worktrees at all: any +checkout can hit it, though initial clones and worktree creation write +the most files. On the build knob, he clarified that `NO_NSEC` is +about whether the nanosecond fields of `struct stat` exist at all, +whereas Git only uses them for stat comparison when `USE_NSEC` is +set. He traced that distinction to c06ff4908b (Record ns-timestamps if +possible, but do not use it without USE_NSEC, 2009-03-04) and mused +that it "ought to be a run-time config, though, and maybe even +something that gets auto-probed by `git init`". + +Junio Hamano, the Git maintainer, replied that he had thought about +auto-probing and could not find a clean way to detect whether a +filesystem loses the nanosecond part of `st_mtime` when "metadata is +flushed and later read back in" without unreasonable cost: "I do not +think we want to trigger system-wide sync and/or dropping of buffer +cache ;-)". brian m. carlson suggested a middle ground: let `git +update-index` take options for this the way it already does for +`--untracked-cache`, so that users who know their platform is safe (he +gave Linux with btrfs as his own example) can opt in at runtime, +possibly with a `--test-use-nsec` mode that inspects `uname` and +`statfs` for known-good configurations. + +### A conditional that looked dead + +Ben came back to the thread a while later having followed Peff's +pointer to `git status`. He found that `cmd_status()` calls +`refresh_index()` and `repo_updated_index_if_able()`, and that the +same pair is wrapped in `refresh_index_quietly()` in `builtin/diff.c`, +but that the call there is guarded by a condition that, on his system, +never fired. The guard dates to aecbf914c4 (git-diff: resurrect the +traditional empty "diff --git" behaviour, 2007-08-31), and Ben's +reading of it was that the double negation of a boolean could never +exceed 1, so he asked: "So… has that conditional been quietly dead all +this time? I can't imagine that's right, but…". He also confirmed that +adding `USE_NSEC` to his build did make the problem go away, and said +he would send the Meson patch anyway "for folks to have the knob", +although it now felt like a band-aid to him. + +Junio explained what the guard actually means. The `skip_stat_unmatch` +member of the diff options is not a boolean but a 1-based counter: it is +initialised to 1 when auto-refresh-index is enabled, which is what causes +`diffcore_std()` to call `diffcore_skip_stat_unmatch()` at all, and that +function then increments it once for every path that appeared in the diff +only because it was stat-dirty without an actual content change. So +comparing it against 1 asks "did we find any such ghost changes?", and on +Ben's system the answer was simply no. Junio added that he had initially +suspected "an embarrassing thinko" himself, and that whether such a +dual-purpose counter is a good idea is another matter: "Apparently it +confused both of us in this case ;-)". He followed up with a pointer to +[the 2007 discussion](https://lore.kernel.org/git/20070830063810.GD16312@mellanox.co.il/) +in which that patch was written. + +Peff replied that this was the core of the issue, and added the missing +piece: the racily-clean entries *are* dirty in the sense that their mtimes +match the index mtime, so Git double-checks their contents. But +`diffcore_skip_stat_unmatch()` does not count them, so the counter stays +at 1, `git diff` never writes out a refreshed index, "and thus every +subsequent diff repeats the same expensive double-check." He was unsure +where the blame lay: either `diffcore_skip_stat_unmatch()` should count +them, or the index should mark them differently by truncating their cached +size to zero, as the racy-git document describes. Though he noted the +latter would be user-visible, since plumbing like `git diff-files`, which +does not update the index, would then report a spurious diff. To Junio's +remark about the confusing counter he added: "Make that three of us. ;)" + +In a follow-up to himself, Peff observed that `diffcore` does not even have +the information it would need, because the racy handling is hidden inside +`ie_match_stat()`, which returns only "changed" flags and so cannot +distinguish "stat matched and the timestamp was not racy" from "the +timestamp was racy, we compared contents, and found nothing". He posted an +experimental patch passing a `DIFF_RACY_IS_MODIFIED` flag down from +`builtin_diff_files()` so those entries are counted as stat-dirty while +still being suppressed from the output. It worked, in that `git diff` then +refreshed the index, but the timings were odd: in a linux.git working tree +with many racy entries the first diff went from about 500ms (repeated +forever) to 1800ms, and about 30ms thereafter. He could account for a +doubling from the from-scratch index refresh, but not the remaining 800ms, +guessing that `diff_filespec_check_stat_unmatch()` is somehow slower than +`ce_modified_check_fs()`. His overall verdict: "This feels like a case we +could do a bit better at, but I wonder how much it matters in practice. As +soon as you do any index-refresh (including `git status`), the racy entries +are cleared and everything is faster. It just seems kind of lame that we +write out the initial working tree with so many racy entries." + +### Could nanoseconds just make the problem go away? + +Junio picked up that last point with a suggestion: the reason Git does +not simply wait before writing the index is that stalling for a full +second was unacceptable back when sub-second resolution was not used +anywhere, but "with nanosecond resolution timestamps in place, we +could delay writing the index file by 50 milliseconds, nobody notices +the delay, and raciness would go away, perhaps?" + +Peff agreed that would require comparing index and file mtimes at +nanosecond precision, and then made a sharper observation: once you +are comparing nanoseconds, no delay is needed at all. Writing out all +of linux.git takes roughly five seconds, so about 20% of the files +share the index's one-second timestamp. With nanosecond resolution, +that collision rate should drop by around a billion, and even an +unlucky single file would not matter. Better still, the comparison +code already exists in `is_racy_stat()`. It is just gated on +`USE_NSEC`. He showed a small patch removing the `#ifdef` (with a +debugging `warning()` thrown in) that made the problem disappear, +while wondering aloud whether he was overlooking whatever concern made +`USE_NSEC` conditional in the first place. Junio's reply to that was +simply "That's cute." + +Junio then articulated the concern. Because the nanosecond part can be +lost when an inode is evicted from the kernel's cache and re-read, a +file and the index could be written within the same millisecond and be +distinguishable at nanosecond resolution. But if only one of the two +loses its sub-second component, the comparison can come out the wrong +way. Peff worked through this carefully and conceded the point: the +index does not store its own mtime, so it is `fstat()`ed fresh at read +time and may show a truncated value, which happens to fail in the safe +direction (the index looks older, so a file looks possibly racy and +gets checked). But he could not rule out truncation in the other +direction, which would require the tracked file to be written, evicted +and re-read all within the same second that the index is written, +while the index inode itself is never evicted. It's "unlikely but not +impossible". His conclusion: "it's all sufficiently scary that I think +it should stay conditional on `USE_NSEC`", while suspecting `USE_NSEC` +is in fact safe on Linux these days. + +Separately, Junio proposed a cleaner alternative to Peff's +flag-passing patch: since `ie_match_stat()` already has access to the +index state, it could set a bit in `struct index_state`, next to +`updated_workdir` and friends, whenever a racy timestamp sends it down +the compare-data path, and the auto-refresh decision could then +consult that bit. Peff thought that "sounds fairly clean", though he +preferred the nanosecond route if it pans out. Junio also wondered, as +a tangent, why `refresh_index_quietly()` is called from the central +code path in `cmd_diff()` at all, since it should not matter when +comparing two tree objects. Peff suggested it could probably move into +`builtin_diff_files()`, and noted that `git diff` does not honour +`--no-optional-locks`, which is currently respected only by `git +status`. When that latter option was added, the idea was that people +would extend it to other commands as they hit the need, and apparently +nobody has for `git diff`. + +### Where it stands + +Ben closed out the thread saying he would like to dig further but was not +sure when he would find the time, being "deep in the guts of 2 systems +whose implementation are quite foreign to me — the index and the diff +machinery". He restated his own priority as a user: he is happy to pay for +a slow first prompt if subsequent ones are fast, rather than having to +remember and explain to colleagues that "oh, this is racy git, just run +`git status` to fix it". He identified the two remaining avenues as (1) the +cost of that refreshing diff and (2) limiting racy entries on the initial +index write, understanding the latter to have been settled in favour of +keeping the `USE_NSEC` gate, and pointing readers to the separate Meson +thread discussed below for that part of the story. On the former he noted +that the discussion of how to communicate the necessary bits to the diff +code had not come with updated measurements, and that turning Junio's +suggestions into code would take him some time. + +### The build knob that turned into a design question + +The one patch that came directly out of this thread was Ben's +[Meson build knob](https://lore.kernel.org/git/c4c5ade901ff95b0f95939ea818870e4f3d59da1.1781971201.git.ben.knoble+github@gmail.com), +sent under the title "meson: wire up USE_NSEC build knob", which observed +that "autotools-style builds permit enabling `USE_NSEC` for cases where +that's desired; the equivalent knob is missing from meson-based builds". It +added a `nanosec` option to `meson_options.txt` and passed `-DUSE_NSEC` +accordingly, so six lines in total, and deliberately no change of defaults. + +Junio welcomed it as "a welcome addition to the other side of the world", +while wondering whether `meson setup -Dnanosec=true` was easy to discover, +and said he would queue it. Ben agreed the name was up for debate, and +Patrick Steinhardt reassured them both that Meson options are easy enough +to discover by running `meson setup` in the source directory. + +Peff called the patch reasonable, since it only brings Meson to parity with +the Makefile, but reiterated that he was "not still not sure if turning on +`USE_NSEC` is a good idea", quoting the passage of +`Documentation/technical/racy-git.adoc` that explains why: in-core +timestamps can have finer granularity than on-disk ones, so an evicted +inode can come back with a different mtime. That was fixed in Linux 2.6.11, +but only for filesystems with exactly 1ns or 1s resolution, leaving CEPH, +CIFS, NTFS and UDF broken. He called it "the most succinct description of +the problem I've seen", while having "no idea how widely it still applies". + +Patrick took that further, and this is where the topic began to shift: +if the mechanism is still subtly broken, "it might even make sense to +remove the build option completely. It doesn't really make sense in my +opinion to have a build option that nobody uses and that is subtly +broken when enabled." Rather than speculate, Peff went and +measured. He proposed a test: `touch` a file, record `ls --full-time`, +drop the kernel caches via `/proc/sys/vm/drop_caches`, and look +again. He then reported that ext4, a loopback ext2 mount and even vfat +all survived it, the last because Linux limits the cached VFS response +to what the underlying filesystem can represent. "So...maybe this is +just a non-issue these days, at least on Linux?" He followed up having +found an [old thread](https://public-inbox.org/git/5605D88A.20104%40gmail.com/) +indicating CEPH, CIFS, NTFS, UFS and FUSE were fixed in kernel 4.3, +tested CIFS himself successfully, and noted with amusement that "FAT +systems were fixed since 2015. ;)". He raised one further subtlety: +implementations with different resolutions, such as JGit using +millisecond APIs, interoperate correctly only as long as each compares +consistently in its own resolution. And a millisecond-resolution +index read by a `USE_NSEC` Git would look entirely stat-dirty, a +performance rather than correctness problem that "nobody may have +noticed, because probably hardly anybody bothers to build with +`USE_NSEC` now." Ben later contributed his own data point, reporting +nanosecond precision surviving a dropped cache on XFS. + +brian m. carlson argued for going further still: provide a config knob +and build with `USE_NSEC` by default, since most people are on Linux +with filesystems now known to be fine, with an easy escape hatch and a +possible `statfs`-based check later. Patrick reached a similar place +from the opposite direction. He thought that if correctness depends on +the filesystem, a *build* option is too coarse-grained, because "a +distro wouldn't really be able to ever enable the option, unless it +knew that repositories will only ever exist on a filesystem that +works", and suggested treating it like `core.ignoreCase`: compile +nanosecond support in unconditionally where the platform supports it, +and let users opt in at runtime, ideally with `git init` setting it +automatically. + +Junio pushed back partially, noting that build options are not only +for distro packagers aiming at the widest audience, and drawing a +careful distinction: `core.ignoreCase` *must* be set for correct +operation on a case-insensitive filesystem and is "not something you +set by choice", whereas nanosecond timestamps need not be enabled even +where they work perfectly, and must be disabled where precision is +randomly lost. Peff agreed with the general direction anyway saying +"it should be a config flag and not a build option. Run-time flags are +more friendly to users when there is no good reason to avoid them" +while pointing out that auto-detection founders on the need to flush +the kernel's inode cache, which is neither portable nor something to +inflict on every repository creation, and that he had been unable to +make the failure reproduce at all on modern Linux. + +Ben, apologising for a delay caused by not watching "What's cooking", +offered to "noodle in that direction" toward a runtime flag, while noting +it means considerably more surgery than exposing the Meson option and that +he was unsure how to write a test for it. He also observed, half-joking, +that the logical conclusion of the discussion would otherwise be to remove +the option from the Makefile too. Patrick replied that no detection +mechanism was strictly needed to start with: keep the current default, +compile nanosecond support in where available, and add a config opt-in. +Peff agreed that "even if we eventually auto-detect, the first step is +adding the config at all", and said he was agnostic about adding +`USE_NSEC` to Meson in the meantime, leaning towards removing it from the +Makefile entirely once a runtime config exists. + +At that point Junio drew the conclusion for the topic as a whole: +"the discussion tells me that if we were to pursue this topic further, it +would not primarily be about adding the build knob to meson.build file, but +rather a bit more involved to affect the product for everybody regardless +of the build framework used. So I think it is safe for me +[discard this topic from my tree](https://lore.kernel.org/git/xmqqa4rx9mb5.fsf@gitster.g) +for now, with an invitation to resurrect it as a topic with shifted focus." +Ben [confirmed](https://lore.kernel.org/git/45F2C180-1DE1-4371-869B-BF605B64E01A@gmail.com) +he had been meaning to send a "please discard" message himself "per the new +guidelines ;) been on vacation." + +The `dk/meson-enable-use-nsec-build` topic accordingly travelled through +"Waiting for response(s) to review comment(s)" and "Expecting a reroll" to +"Will discard" in the July "What's cooking" reports, and was listed as +"Discarded" in +[What's cooking in git.git (Jul 2026, #08)](https://lore.kernel.org/git/xmqqa4rnpgfk.fsf@gitster.g). +It never reached `next` or `master`, and no successor topic implementing +the runtime configuration has appeared on the list so far. + +### Conclusion + +No code has landed from either thread, and the one patch that was sent +ended up discarded. Yet both discussions were productive. A report +framed as a worktree performance bug turned out to have nothing to do +with worktrees: it is racy Git, triggered by any operation that writes +many files and then an index within the same second, which is why +fresh clones and new worktrees are the usual victims. Along the way +the participants established that `git diff` refreshes the index but +then throws the work away, because the racily-clean entries it +double-checked are never counted as stat-dirty and so the refreshed +index is never written back, which is why the cost repeats on every +invocation until something else, such as `git status` or +`git update-index --refresh`, rewrites the index. Two concrete designs +were sketched for fixing that: counting racy entries via a diff flag, +or smudging a bit in `struct index_state`. + +The more attractive possibility, making racy entries vanishingly rare +by comparing nanosecond timestamps, is where the two threads +converge. What began as a six-line build-system patch became an +investigation into whether the twenty-year-old reason for keeping +`USE_NSEC` off by default still holds. Evidence was gathered from +Peff's cache-dropping experiments on ext4, ext2, vfat and CIFS, Ben's +on XFS, and the kernel history showing the remaining filesystems fixed +by 4.3. It suggests the reason largely does not hold anymore, at least +on Linux. That in turn convinced the participants that a compile-time +switch is the wrong shape for the problem, since correctness depends +on the filesystem a repository happens to live on rather than on how +Git was built, and that a runtime configuration variable is what is +really wanted. Junio discarded the Meson patch not because it was +wrong but because it had been overtaken by that conclusion, explicitly +inviting a resurrection "as a topic with shifted focus". Ben has +offered to attempt it. + +So the lasting value here is a clarified problem and a mandate for a better +solution, plus a nice illustration of how a small patch can usefully expose +a design question that outgrows it. For users hitting the slowness today, +the practical advice is unchanged and worth repeating: after a large +checkout, one `git status` or `git update-index --refresh` makes it go +away. + + + + + + + +## Other News + +__Various__ + + +__Light reading__ + + + +__Git tools and sites__ + + +## Releases + + +## Credits + +This edition of Git Rev News was curated by +Christian Couder <>, +Jakub Narębski <>, +Markus Jansen <> and +Kaartic Sivaraam <> +with help from XXX.
