Minor releases will not break backwards compatibility unless there is +a very strong reason to do so, like for example a security vulnerability. + +Regardless of that, due to the age of the Git project, it is only natural to +accumulate a backlog of backwards-incompatible changes that will eventually be +required to keep the project aligned with a changing world. These changes fall +into several categories: + +* Changes to long established defaults. +* Concepts that have been replaced with a superior design. +* Concepts, commands, configuration or options that have been lacking in major + ways and that cannot be fixed and which will thus be removed without any + replacement. + +Explicitly not included in this list are fixes to minor bugs that may cause a +change in user-visible behavior. + +The Git project irregularly releases breaking versions that deliberately break +backwards compatibility with older versions. This is done to ensure that Git +remains relevant, safe and maintainable going forward. The release cadence of +breaking versions is typically measured in multiple years. We had the following +major breaking releases in the past: + +* Git 1.6.0, released in August 2008. +* Git 2.0, released in May 2014. + +We use <major>.<minor> release numbers these days, starting from Git 2.0. For +future releases, our plan is to increment <major> in the release number when we +make the next breaking release. Before Git 2.0, the release numbers were +1.<major>.<minor> with the intention to increment <major> for "usual" breaking +releases, reserving the jump to Git 2.0 for really large backward-compatibility +breaking changes. + +The intent of this document is to track upcoming deprecations for future +breaking releases. Furthermore, this document also tracks what will _not_ be +deprecated. This is done such that the outcome of discussions document both +when the discussion favors deprecation, but also when it rejects a deprecation. + +Items should have a clear summary of the reasons why we do or do not want to +make the described change that can be easily understood without having to read +the mailing list discussions. If there are alternatives to the changed feature, +those alternatives should be pointed out to our users. + +All items should be accompanied by references to relevant mailing list threads +where the deprecation was discussed. These references use message-IDs, which +can visited via + + https://lore.kernel.org/git/$message_id/ + +to see the message and its surrounding discussion. Such a reference is there to +make it easier for you to find how the project reached consensus on the +described item back then. + +This is a living document as the environment surrounding the project changes +over time. If circumstances change, an earlier decision to deprecate or change +something may need to be revisited from time to time. So do not take items on +this list to mean "it is settled, do not waste our time bringing it up again". + +== Git 3.0 + +The following subsections document upcoming breaking changes for Git 3.0. There +is no planned release date for this breaking version yet. + +Proposed changes and removals only include items which are "ready" to be done. +In other words, this is not supposed to be a wishlist of features that should +be changed to or replaced in case the alternative was implemented already. + +=== Changes + +* The default hash function for new repositories will be changed from "sha1" + to "sha256". SHA-1 has been deprecated by NIST in 2011 and is nowadays + recommended against in FIPS 140-2 and similar certifications. Furthermore, + there are practical attacks on SHA-1 that weaken its cryptographic properties: ++ + ** The SHAppening (2015). The first demonstration of a practical attack + against SHA-1 with 2^57 operations. + ** SHAttered (2017). Generation of two valid PDF files with 2^63 operations. + ** Birthday-Near-Collision (2019). This attack allows for chosen prefix + attacks with 2^68 operations. + ** Shambles (2020). This attack allows for chosen prefix attacks with 2^63 + operations. ++ +While we have protections in place against known attacks, it is expected +that more attacks against SHA-1 will be found by future research. Paired +with the ever-growing capability of hardware, it is only a matter of time +before SHA-1 will be considered broken completely. We want to be prepared +and will thus change the default hash algorithm to "sha256" for newly +initialized repositories. ++ +An important requirement for this change is that the ecosystem is ready to +support the "sha256" object format. This includes popular Git libraries, +applications and forges. ++ +There is no plan to deprecate the "sha1" object format at this point in time. ++ +Cf. <2f5de416-04ba-c23d-1e0b-83bb655829a7@zombino.com>, +<20170223155046.e7nxivfwqqoprsqj@LykOS.localdomain>, +<CA+EOSBncr=4a4d8n9xS4FNehyebpmX8JiUwCsXD47EQDE+DiUQ@mail.gmail.com>. + +=== Removals + +* Support for grafting commits has long been superseded by git-replace(1). + Grafts are inferior to replacement refs: ++ + ** Grafts are a local-only mechanism and cannot be shared across + repositories. + ** Grafts can lead to hard-to-diagnose problems when transferring objects + between repositories. ++ +The grafting mechanism has been marked as outdated since e650d0643b (docs: mark +info/grafts as outdated, 2014-03-05) and will be removed. ++ +Cf. <20140304174806.GA11561@sigill.intra.peff.net>. + +== Superseded features that will not be deprecated + +Some features have gained newer replacements that aim to improve the design in +certain ways. The fact that there is a replacement does not automatically mean +that the old way of doing things will eventually be removed. This section tracks +those features with newer alternatives. + +* The features git-checkout(1) offers are covered by the pair of commands + git-restore(1) and git-switch(1). Because the use of git-checkout(1) is still + widespread, and it is not expected that this will change anytime soon, all + three commands will stay. ++ +This decision may get revisited in case we ever figure out that there are +almost no users of any of the commands anymore. ++ +Cf. <xmqqttjazwwa.fsf@gitster.g>, +<xmqqleeubork.fsf@gitster.g>, +<112b6568912a6de6672bf5592c3a718e@manjaro.org>. diff --git a/Documentation/Makefile b/Documentation/Makefile index a04da672c6..dc65759cb1 100644 --- a/Documentation/Makefile +++ b/Documentation/Makefile @@ -51,6 +51,7 @@ MAN7_TXT += gitdiffcore.txt MAN7_TXT += giteveryday.txt MAN7_TXT += gitfaq.txt MAN7_TXT += gitglossary.txt +MAN7_TXT += gitpacking.txt MAN7_TXT += gitnamespaces.txt MAN7_TXT += gitremote-helpers.txt MAN7_TXT += gitrevisions.txt @@ -485,12 +486,16 @@ $(LINT_DOCS_FSCK_MSGIDS): ../fsck.h fsck-msgids.txt lint-docs-fsck-msgids: $(LINT_DOCS_FSCK_MSGIDS) +lint-docs-manpages: + $(QUIET_GEN)./lint-manpages.sh + ## Lint: list of targets above .PHONY: lint-docs lint-docs: lint-docs-fsck-msgids lint-docs: lint-docs-gitlink lint-docs: lint-docs-man-end-blurb lint-docs: lint-docs-man-section-order +lint-docs: lint-docs-manpages ifeq ($(wildcard po/Makefile),po/Makefile) doc-l10n install-l10n:: diff --git a/Documentation/RelNotes/2.45.3.txt b/Documentation/RelNotes/2.45.3.txt new file mode 100644 index 0000000000..2a1e9aa608 --- /dev/null +++ b/Documentation/RelNotes/2.45.3.txt @@ -0,0 +1,107 @@ +Git v2.45.3 Release Notes +========================= + +This primarily is to backport various small fixes accumulated on the +'master' front during the development towards Git 2.46, the next +feature release. + + +Fixes since v2.45.2 +------------------- + + * Git-GUI has a new maintainer, Johannes Sixt. + + * Tests that try to corrupt in-repository files in chunked format did + not work well on macOS due to its broken "mv", which has been + worked around. + + * The maximum size of attribute files is enforced more consistently. + + * Unbreak CI jobs so that we do not attempt to use Python 2 that has + been removed from the platform. + + * Git 2.43 started using the tree of HEAD as the source of attributes + in a bare repository, which has severe performance implications. + For now, revert the change, without ripping out a more explicit + support for the attr.tree configuration variable. + + * Windows CI running in GitHub Actions started complaining about the + order of arguments given to calloc(); the imported regex code uses + the wrong order almost consistently, which has been corrected. + + * The SubmittingPatches document now refers folks to manpages + translation project. + + * "git rebase --signoff" used to forget that it needs to add a + sign-off to the resulting commit when told to continue after a + conflict stops its operation. + + * The procedure to build multi-pack-index got confused by the + replace-refs mechanism, which has been corrected by disabling the + latter. + + * "git stash -S" did not handle binary files correctly, which has + been corrected. + + * A scheduled "git maintenance" job is expected to work on all + repositories it knows about, but it stopped at the first one that + errored out.

Over time, those +scattered bits may coalesce into this document. + +== Pseudo-merge bitmaps + +NOTE: Pseudo-merge bitmaps are considered an experimental feature, so +the configuration and many of the ideas are subject to change. + +=== Background + +Reachability bitmaps are most efficient when we have on-disk stored +bitmaps for one or more of the starting points of a traversal. For this +reason, Git prefers storing bitmaps for commits at the tips of refs, +because traversals tend to start with those points. + +But if you have a large number of refs, it's not feasible to store a +bitmap for _every_ ref tip. It takes up space, and just OR-ing all of +those bitmaps together is expensive. + +One way we can deal with that is to create bitmaps that represent +_groups_ of refs. When a traversal asks about the entire group, then we +can use this single bitmap instead of considering each ref individually. +Because these bitmaps represent the set of objects which would be +reachable in a hypothetical merge of all of the commits, we call them +pseudo-merge bitmaps. + +=== Overview + +A "pseudo-merge bitmap" is used to refer to a pair of bitmaps, as +follows: + +Commit bitmap:: + + A bitmap whose set bits describe the set of commits included in the + pseudo-merge's "merge" bitmap (as below). + +Merge bitmap:: + + A bitmap whose set bits describe the reachability closure over the set + of commits in the pseudo-merge's "commits" bitmap (as above). An + identical bitmap would be generated for an octopus merge with the same + set of parents as described in the commits bitmap. + +Pseudo-merge bitmaps can accelerate bitmap traversals when all commits +for a given pseudo-merge are listed on either side of the traversal, +either directly (by explicitly asking for them as part of the `HAVES` +or `WANTS`) or indirectly (by encountering them during a fill-in +traversal). + +=== Use-cases + +For example, suppose there exists a pseudo-merge bitmap with a large +number of commits, all of which are listed in the `WANTS` section of +some bitmap traversal query. When pseudo-merge bitmaps are enabled, the +bitmap machinery can quickly determine there is a pseudo-merge which +satisfies some subset of the wanted objects on either side of the query. +Then, we can inflate the EWAH-compressed bitmap, and `OR` it in to the +resulting bitmap. By contrast, without pseudo-merge bitmaps, we would +have to repeat the decompression and `OR`-ing step over a potentially +large number of individual bitmaps, which can take proportionally more +time. + +Another benefit of pseudo-merges arises when there is some combination +of (a) a large number of references, with (b) poor bitmap coverage, and +(c) deep, nested trees, making fill-in traversal relatively expensive. +For example, suppose that there are a large enough number of tags where +bitmapping each of the tags individually is infeasible. Without +pseudo-merge bitmaps, computing the result of, say, `git rev-list +--use-bitmap-index --count --objects --tags` would likely require a +large amount of fill-in traversal. But when a large quantity of those +tags are stored together in a pseudo-merge bitmap, the bitmap machinery +can take advantage of the fact that we only care about the union of +objects reachable from all of those tags, and answer the query much +faster. + +=== Configuration + +Reference tips are grouped into different pseudo-merge groups according +to two criteria. A reference name matches one or more of the defined +pseudo-merge patterns, and optionally one or more capture groups within +that pattern which further partition the group. + +Within a group, commits may be considered "stable", or "unstable" +depending on their age. These are adjusted by setting the +`bitmapPseudoMerge.<name>.stableThreshold` and +`bitmapPseudoMerge.<name>.threshold` configuration values, respectively. + +All stable commits are grouped into pseudo-merges of equal size +(`bitmapPseudoMerge.<name>.stableSize`). If the `stableSize` +configuration is set to, say, 100, then the first 100 commits (ordered +by committer date) which are older than the `stableThreshold` value will +form one group, the next 100 commits will form another group, and so on. + +Among unstable commits, the pseudo-merge machinery will attempt to +combine older commits into large groups as opposed to newer commits +which will appear in smaller groups. This is based on the heuristic that +references whose tip commit is older are less likely to be modified to +point at a different commit than a reference whose tip commit is newer. + +The size of groups is determined by a power-law decay function, and the +decay parameter roughly corresponds to "k" in `f(n) = C*n^(-k/100)`, +where `f(n)` describes the size of the `n`-th pseudo-merge group. The +sample rate controls what percentage of eligible commits are considered +as candidates. The threshold parameter indicates the minimum age (so as +to avoid including too-recent commits in a pseudo-merge group, making it +less likely to be valid). The "maxMerges" parameter sets an upper-bound +on the number of pseudo-merge commits an individual group + +The "stable"-related parameters control "stable" pseudo-merge groups, +comprised of a fixed number of commits which are older than the +configured "stable threshold" value and may be grouped together in +chunks of "stableSize" in order of age. + +The exact configuration for pseudo-merges is as follows: + +include::config/bitmap-pseudo-merge.txt[] + +=== Examples + +Suppose that you have a repository with a large number of references, +and you want a bare-bones configuration of pseudo-merge bitmaps that +will enhance bitmap coverage of the `refs/` namespace. You may start +wiht a configuration like so: + + [bitmapPseudoMerge "all"] + pattern = "refs/" + threshold = now + stableThreshold = never + sampleRate = 100 + maxMerges = 64 + +This will create pseudo-merge bitmaps for all references, regardless of +their age, and group them into 64 pseudo-merge commits. + +If you wanted to separate tags from branches when generating +pseudo-merge commits, you would instead define the pattern with a +capture group, like so: + + [bitmapPseudoMerge "all"] + pattern = "refs/(heads/tags)/" + +Suppose instead that you are working in a fork-network repository, with +each fork specified by some numeric ID, and whose refs reside in +`refs/virtual/NNN/` (where `NNN` is the numeric ID corresponding to some +fork) in the network. In this instance, you may instead write something +like: + + [bitmapPseudoMerge "all"] + pattern = "refs/virtual/([0-9]+)/(heads|tags)/" + threshold = now + stableThreshold = never + sampleRate = 100 + maxMerges = 64 + +Which would generate pseudo-merge group identifiers like "1234-heads", +and "5678-tags" (for branches in fork "1234", and tags in remote "5678", +respectively). + +SEE ALSO +-------- +linkgit:git-pack-objects[1] +linkgit:git-repack[1] + +GIT +--- +Part of the linkgit:git[1] suite diff --git a/Documentation/lint-manpages.sh b/Documentation/lint-manpages.sh new file mode 100755 index 0000000000..92cfc0a15a --- /dev/null +++ b/Documentation/lint-manpages.sh @@ -0,0 +1,108 @@ +#!/bin/sh + +extract_variable () { + ( + cat ../Makefile + cat <<EOF +print_variable: + @\$(foreach b,\$($1),echo XXX \$(b:\$X=) YYY;) +EOF + ) | + make -C .. -f - print_variable 2>/dev/null | + sed -n -e 's/.*XXX \(.*\) YYY.*/\1/p' +} + +check_missing_docs () ( + ret=0 + + for v in $ALL_COMMANDS + do + case "$v" in + git-merge-octopus) continue;; + git-merge-ours) continue;; + git-merge-recursive) continue;; + git-merge-resolve) continue;; + git-merge-subtree) continue;; + git-fsck-objects) continue;; + git-init-db) continue;; + git-remote-*) continue;; + git-stage) continue;; + git-legacy-*) continue;; + git-?*--?* ) continue ;; + esac + + if ! test -f "$v.txt" + then + echo "no doc: $v" + ret=1 + fi + + if ! sed -e '1,/^### command list/d' -e '/^#/d' ../command-list.txt | + grep -q "^$v[ ]" + then + case "$v" in + git) + ;; + *) + echo "no link: $v" + ret=1 + ;; + esac + fi + done + + exit $ret +) + +check_extraneous_docs () { + ( + sed -e '1,/^### command list/d' \ + -e '/^#/d' \ + -e '/guide$/d' \ + -e '/interfaces$/d' \ + -e 's/[ ].*//' \ + -e 's/^/listed /' ../command-list.txt + make print-man1 | + grep '\.txt$' | + sed -e 's|^|documented |' \ + -e 's/\.txt//' + ) | ( + all_commands="$(printf "%s " "$ALL_COMMANDS" "$BUILT_INS" "$EXCLUDED_PROGRAMS" | tr '\n' ' ')" + ret=0 + + while read how cmd + do + case " $all_commands " in + *" $cmd "*) ;; + *) + echo "removed but $how: $cmd" + ret=1;; + esac + done + + exit $ret + ) +} + +BUILT_INS="$(extract_variable BUILT_INS)" +ALL_COMMANDS="$(extract_variable ALL_COMMANDS)" +EXCLUDED_PROGRAMS="$(extract_variable EXCLUDED_PROGRAMS)" + +findings=$( + if ! check_missing_docs + then + ret=1 + fi + + if ! check_extraneous_docs + then + ret=1 + fi + + exit $ret +) +ret=$? + +printf "%s" "$findings" | sort + +exit $ret diff --git a/Documentation/technical/bitmap-format.txt b/Documentation/technical/bitmap-format.txt index f5d200939b..bfb0ec7beb 100644 --- a/Documentation/technical/bitmap-format.txt +++ b/Documentation/technical/bitmap-format.txt @@ -255,3 +255,144 @@ triplet is - xor_row (4 byte integer, network byte order): :: The position of the triplet whose bitmap is used to compress this one, or `0xffffffff` if no such bitmap exists. + +Pseudo-merge bitmaps +-------------------- + +If the `BITMAP_OPT_PSEUDO_MERGES` flag is set, a variable number of +bytes (preceding the name-hash cache, commit lookup table, and trailing +checksum) of the `.bitmap` file is used to store pseudo-merge bitmaps. + +For more information on what pseudo-merges are, why they are useful, and +how to configure them, see the information in linkgit:gitpacking[7]. + +=== File format + +If enabled, pseudo-merge bitmaps are stored in an optional section at +the end of a `.bitmap` file.
