If `-z` is passed, the "lines" are terminated by a NUL +character instead of a newline character. + +[[IM]] +Informational messages +~~~~~~~~~~~~~~~~~~~~~~ + +This always starts with a blank line (or NUL if `-z` is passed) to +separate it from the previous sections, and then has free-form +messages about the merge, such as: + + * "Auto-merging <file>" + * "CONFLICT (rename/delete): <oldfile> renamed...but deleted in..." + * "Failed to merge submodule <submodule> (<reason>)" + * "Warning: cannot merge binary files: <filename>" + +Note that these free-form messages will never have a NUL character +in or between them, even if -z is passed. It is simply a large block +of text taking up the remainder of the output. + +EXIT STATUS +----------- + +For a successful, non-conflicted merge, the exit status is 0. When the +merge has conflicts, the exit status is 1. If the merge is not able to +complete (or start) due to some kind of error, the exit status is +something other than 0 or 1 (and the output is unspecified). + +USAGE NOTES +----------- + +This command is intended as low-level plumbing, similar to +linkgit:git-hash-object[1], linkgit:git-mktree[1], +linkgit:git-commit-tree[1], linkgit:git-write-tree[1], +linkgit:git-update-ref[1], and linkgit:git-mktag[1]. Thus, it can be +used as a part of a series of steps such as: + + NEWTREE=$(git merge-tree --write-tree $BRANCH1 $BRANCH2) + test $? -eq 0 || die "There were conflicts..." + NEWCOMMIT=$(git commit-tree $NEWTREE -p $BRANCH1 -p $BRANCH2) + git update-ref $BRANCH1 $NEWCOMMIT + +Note that when the exit status is non-zero, `NEWTREE` in this sequence +will contain a lot more output than just a tree. + +For conflicts, the output includes the same information that you'd get +with linkgit:git-merge[1]: + + * what would be written to the working tree (the + <<OIDTLT,OID of toplevel tree>>) + * the higher order stages that would be written to the index (the + <<CFI,Conflicted file info>>) + * any messages that would have been printed to stdout (the + <<IM,Informational messages>>) + +MISTAKES TO AVOID +----------------- + +Do NOT look through the resulting toplevel tree to try to find which +files conflict; parse the <<CFI,Conflicted file info>> section instead. +Not only would parsing an entire tree be horrendously slow in large +repositories, there are numerous types of conflicts not representable by +conflict markers (modify/delete, mode conflict, binary file changed on +both sides, file/directory conflicts, various rename conflict +permutations, etc.) + +Do NOT interpret an empty <<CFI,Conflicted file info>> list as a clean +merge; check the exit status. A merge can have conflicts without having +individual files conflict (there are a few types of directory rename +conflicts that fall into this category, and others might also be added +in the future). + +Do NOT attempt to guess or make the user guess the conflict types from +the <<CFI,Conflicted file info>> list. The information there is +insufficient to do so. For example: Rename/rename(1to2) conflicts (both +sides renamed the same file differently) will result in three different +file having higher order stages (but each only has one higher order +stage), with no way (short of the <<IM,Informational messages>> section) +to determine which three files are related. File/directory conflicts +also result in a file with exactly one higher order stage. +Possibly-involved-in-directory-rename conflicts (when +"merge.directoryRenames" is unset or set to "conflicts") also result in +a file with exactly one higher order stage. In all cases, the +<<IM,Informational messages>> section has the necessary info, though it +is not designed to be machine parseable. + +Do NOT assume that each paths from <<CFI,Conflicted file info>>, and +the logical conflicts in the <<IM,Informational messages>> have a +one-to-one mapping, nor that there is a one-to-many mapping, nor a +many-to-one mapping. Many-to-many mappings exist, meaning that each +path can have many logical conflict types in a single merge, and each +logical conflict type can affect many paths. + +Do NOT assume all filenames listed in the <<IM,Informational messages>> +section had conflicts. Messages can be included for files that have no +conflicts, such as "Auto-merging <file>". + +AVOID taking the OIDS from the <<CFI,Conflicted file info>> and +re-merging them to present the conflicts to the user. This will lose +information. Instead, look up the version of the file found within the +<<OIDTLT,OID of toplevel tree>> and show that instead. In particular, +the latter will have conflict markers annotated with the original +branch/commit being merged and, if renames were involved, the original +filename. While you could include the original branch/commit in the +conflict marker annotations when re-merging, the original filename is +not available from the <<CFI,Conflicted file info>> and thus you would +be losing information that might help the user resolve the conflict. + +[[DEPMERGE]] +DEPRECATED DESCRIPTION +---------------------- + +Per the <<NEWMERGE,DESCRIPTION>> and unlike the rest of this +documentation, this section describes the deprecated `--trivial-merge` +mode. + +Other than the optional `--trivial-merge`, this mode accepts no +options. + +This mode reads three tree-ish, and outputs trivial merge results and +conflicting stages to the standard output in a semi-diff format. +Since this was designed for higher level scripts to consume and merge +the results back into the index, it omits entries that match +<branch1>. The result of this second form is similar to what +three-way 'git read-tree -m' does, but instead of storing the results +in the index, the command outputs the entries to the standard output. + +This form not only has limited applicability (a trivial merge cannot +handle content merges of individual files, rename detection, proper +directory/file conflict handling, etc.), the output format is also +difficult to work with, and it will generally be less performant than +the first form even on successful merges (especially if working in +large repositories).

It accomplishes this by helping users to take advantage of +advanced performance features in Git. Unlike most other Git built-in commands, +Scalar is not executed as a subcommand of 'git'; rather, it is built as a +separate executable containing its own series of subcommands. + +Background +---------- + +Scalar was originally designed as an add-on to Git and implemented as a .NET +Core application. It was created based on the learnings from the VFS for Git +project (another application aimed at improving the experience of working with +large repositories). As part of its initial implementation, Scalar relied on +custom features in the Microsoft fork of Git that have since been integrated +into core Git: + +* partial clone, +* commit graphs, +* multi-pack index, +* sparse checkout (cone mode), +* scheduled background maintenance, +* etc + +With the requisite Git functionality in place and a desire to bring the benefits +of Scalar to the larger Git community, the Scalar application itself was ported +from C# to C and integrated upstream. + +Features +-------- + +Scalar is comprised of two major pieces of functionality: automatically +configuring built-in Git performance features and managing repository +enlistments. + +The Git performance features configured by Scalar (see "Background" for +examples) confer substantial performance benefits to large repositories, but are +either too experimental to enable for all of Git yet, or only benefit large +repositories. As new features are introduced, Scalar should be updated +accordingly to incorporate them. This will prevent the tool from becoming stale +while also providing a path for more easily bringing features to the appropriate +users. + +Enlistments are how Scalar knows which repositories on a user's system should +utilize Scalar-configured features. This allows it to update performance +settings when new ones are added to the tool, as well as centrally manage +repository maintenance. The enlistment structure - a root directory with a +`src/` subdirectory containing the cloned repository itself - is designed to +encourage users to route build outputs outside of the repository to avoid the +performance-limiting overhead of ignoring those files in Git. + +Design +------ + +Scalar is implemented in C and interacts with Git via a mix of child process +invocations of Git and direct usage of `libgit.a`. Internally, it is structured +much like other built-ins with subcommands (e.g., `git stash`), containing a +`cmd_<subcommand>()` function for each subcommand, routed through a `cmd_main()` +function. Most options are unique to each subcommand, with `scalar` respecting +some "global" `git` options (e.g., `-c` and `-C`). + +Because `scalar` is not invoked as a Git subcommand (like `git scalar`), it is +built and installed as its own executable in the `bin/` directory, alongside +`git`, `git-gui`, etc. + +Roadmap +------- + +NOTE: this section will be removed once the remaining tasks outlined in this +roadmap are complete. + +Scalar is a large enough project that it is being upstreamed incrementally, +living in `contrib/` until it is feature-complete. So far, the following patch +series have been accepted: + +- `scalar-the-beginning`: The initial patch series which sets up + `contrib/scalar/` and populates it with a minimal `scalar` command that + demonstrates the fundamental ideas. + +- `scalar-c-and-C`: The `scalar` command learns about two options that can be + specified before the command, `-c <key>=<value>` and `-C <directory>`. + +- `scalar-diagnose`: The `scalar` command is taught the `diagnose` subcommand. + +Roughly speaking (and subject to change), the following series are needed to +"finish" this initial version of Scalar: + +- Finish Scalar features: Enable the built-in FSMonitor in Scalar enlistments + and implement `scalar help`. At the end of this series, Scalar should be + feature-complete from the perspective of a user. + +- Generalize features not specific to Scalar: In the spirit of making Scalar + configure only what is needed for large repo performance, move common + utilities into other parts of Git. Some of this will be internal-only, but one + major change will be generalizing `scalar diagnose` for use with any Git + repository. + +- Move Scalar to toplevel: Move Scalar out of `contrib/` and into the root of + `git`, including updates to build and install it with the rest of Git. This + change will incorporate Scalar into the Git CI and test framework, as well as + expand regression and performance testing to ensure the tool is stable. + +Finally, there are two additional patch series that exist in Microsoft's fork of +Git, but there is no current plan to upstream them. There are some interesting +ideas there, but the implementation is too specific to Azure Repos and/or VFS +for Git to be of much help in general. + +These still exist mainly because the GVFS protocol is what Azure Repos has +instead of partial clone, while Git is focused on improving partial clone: + +- `scalar-with-gvfs`: The primary purpose of this patch series is to support + existing Scalar users whose repositories are hosted in Azure Repos (which does + not support Git's partial clones, but supports its predecessor, the GVFS + protocol, which is used by Scalar to emulate the partial clone). + + Since the GVFS protocol will never be supported by core Git, this patch series + will remain in Microsoft's fork of Git. + +- `run-scalar-functional-tests`: The Scalar project developed a quite + comprehensive set of integration tests (or, "Functional Tests"). They are the + sole remaining part of the original C#-based Scalar project, and this patch + adds a GitHub workflow that runs them all. + + Since the tests partially depend on features that are only provided in the + `scalar-with-gvfs` patch series, this patch cannot be upstreamed. diff --git a/GIT-VERSION-GEN b/GIT-VERSION-GEN index 1b2c580ecc..6ec9e34282 100755 --- a/GIT-VERSION-GEN +++ b/GIT-VERSION-GEN @@ -1,7 +1,7 @@ #!/bin/sh GVF=GIT-VERSION-FILE -DEF_VER=v2.37.1 +DEF_VER=v2.37.GIT LF=' ' @@ -182,6 +182,8 @@ include shared.mak # # Define BLK_SHA256 to use the built-in SHA-256 routines. # +# Define NETTLE_SHA256 to use the SHA-256 routines in libnettle. +# # Define GCRYPT_SHA256 to use the SHA-256 routines in libgcrypt. # # Define OPENSSL_SHA256 to use the SHA-256 routines in OpenSSL. @@ -309,6 +311,11 @@ include shared.mak # distributions that want to use their packaged versions of Perl # modules, instead of the fallbacks shipped with Git. # +# Define NO_GITWEB if you do not want to build or install +# 'gitweb'.
