For example, the current maintainer of Git uses "Junio + C Hamano". This will be the name portion that is stored in every commit + you make. ++ +This configuration doesn't have any effect on authenticating to remote services; +for that, see `credential.username` in linkgit:git-config[1]. + +[[http-postbuffer]] +What does `http.postBuffer` really do?:: + This option changes the size of the buffer that Git uses when pushing + data to a remote over HTTP or HTTPS. If the data is larger than this + size, libcurl, which handles the HTTP support for Git, will use chunked + transfer encoding since it isn't known ahead of time what the size of + the pushed data will be. ++ +Leaving this value at the default size is fine unless you know that either the +remote server or a proxy in the middle doesn't support HTTP/1.1 (which +introduced the chunked transfer encoding) or is known to be broken with chunked +data. This is often (erroneously) suggested as a solution for generic push +problems, but since almost every server and proxy supports at least HTTP/1.1, +raising this value usually doesn't solve most push problems. A server or proxy +that didn't correctly support HTTP/1.1 and chunked transfer encoding wouldn't be +that useful on the Internet today, since it would break lots of traffic. ++ +Note that increasing this value will increase the memory used on every relevant +push that Git does over HTTP or HTTPS, since the entire buffer is allocated +regardless of whether or not it is all used. Thus, it's best to leave it at the +default unless you are sure you need a different value. + +[[configure-editor]] +How do I configure a different editor?:: + If you haven't specified an editor specifically for Git, it will by default + use the editor you've configured using the `VISUAL` or `EDITOR` environment + variables, or if neither is specified, the system default (which is usually + `vi`). Since some people find `vi` difficult to use or prefer a different + editor, it may be desirable to change the editor used. ++ +If you want to configure a general editor for most programs which need one, you +can edit your shell configuration (e.g., `~/.bashrc` or `~/.zshenv`) to contain +a line setting the `EDITOR` or `VISUAL` environment variable to an appropriate +value. For example, if you prefer the editor `nano`, then you could write the +following: ++ +---- +export VISUAL=nano +---- ++ +If you want to configure an editor specifically for Git, you can either set the +`core.editor` configuration value or the `GIT_EDITOR` environment variable. You +can see linkgit:git-var[1] for details on the order in which these options are +consulted. ++ +Note that in all cases, the editor value will be passed to the shell, so any +arguments containing spaces should be appropriately quoted. Additionally, if +your editor normally detaches from the terminal when invoked, you should specify +it with an argument that makes it not do that, or else Git will not see any +changes. An example of a configuration addressing both of these issues on +Windows would be the configuration `"C:\Program Files\Vim\gvim.exe" --nofork`, +which quotes the filename with spaces and specifies the `--nofork` option to +avoid backgrounding the process. + +Credentials +----------- + +[[http-credentials]] +How do I specify my credentials when pushing over HTTP?:: + The easiest way to do this is to use a credential helper via the + `credential.helper` configuration. Most systems provide a standard + choice to integrate with the system credential manager. For example, + Git for Windows provides the `wincred` credential manager, macOS has the + `osxkeychain` credential manager, and Unix systems with a standard + desktop environment can use the `libsecret` credential manager. All of + these store credentials in an encrypted store to keep your passwords or + tokens secure. ++ +In addition, you can use the `store` credential manager which stores in a file +in your home directory, or the `cache` credential manager, which does not +permanently store your credentials, but does prevent you from being prompted for +them for a certain period of time. ++ +You can also just enter your password when prompted. While it is possible to +place the password (which must be percent-encoded) in the URL, this is not +particularly secure and can lead to accidental exposure of credentials, so it is +not recommended. + +[[http-credentials-environment]] +How do I read a password or token from an environment variable?:: + The `credential.helper` configuration option can also take an arbitrary + shell command that produces the credential protocol on standard output. + This is useful when passing credentials into a container, for example. ++ +Such a shell command can be specified by starting the option value with an +exclamation point. If your password or token were stored in the `GIT_TOKEN`, +you could run the following command to set your credential helper: ++ +---- +$ git config credential.helper \ + '!f() { echo username=author; echo "password=$GIT_TOKEN"; };f' +---- + +[[http-reset-credentials]] +How do I change the password or token I've saved in my credential manager?:: + Usually, if the password or token is invalid, Git will erase it and + prompt for a new one. However, there are times when this doesn't always + happen. To change the password or token, you can erase the existing + credentials and then Git will prompt for new ones. To erase + credentials, use a syntax like the following (substituting your username + and the hostname): ++ +---- +$ echo url=https://author@git.example.org | git credential reject +---- + +[[multiple-accounts-http]] +How do I use multiple accounts with the same hosting provider using HTTP?:: + Usually the easiest way to distinguish between these accounts is to use + the username in the URL. For example, if you have the accounts `author` + and `committer` on `git.example.org`, you can use the URLs + https://author@git.example.org/org1/project1.git and + https://committer@git.example.org/org2/project2.git. This way, when you + use a credential helper, it will automatically try to look up the + correct credentials for your account. If you already have a remote set + up, you can change the URL with something like `git remote set-url + origin https://author@git.example.org/org1/project1.git` (see + linkgit:git-remote[1] for details). + +[[multiple-accounts-ssh]] +How do I use multiple accounts with the same hosting provider using SSH?:: + With most hosting providers that support SSH, a single key pair uniquely + identifies a user. Therefore, to use multiple accounts, it's necessary + to create a key pair for each account. If you're using a reasonably + modern OpenSSH version, you can create a new key pair with something + like `ssh-keygen -t ed25519 -f ~/.ssh/id_committer`. You can then + register the public key (in this case, `~/.ssh/id_committer.pub`; note + the `.pub`) with the hosting provider. ++ +Most hosting providers use a single SSH account for pushing; that is, all users +push to the `git` account (e.g., `git@git.example.org`). If that's the case for +your provider, you can set up multiple aliases in SSH to make it clear which key +pair to use. For example, you could write something like the following in +`~/.ssh/config`, substituting the proper private key file: ++ +---- +# This is the account for author on git.example.org. +Host example_author + HostName git.example.org + User git + # This is the key pair registered for author with git.example.org. + IdentityFile ~/.ssh/id_author + IdentitiesOnly yes +# This is the account for committer on git.example.org. +Host example_committer + HostName git.example.org + User git + # This is the key pair registered for committer with git.example.org. + IdentityFile ~/.ssh/id_committer + IdentitiesOnly yes +---- ++ +Then, you can adjust your push URL to use `git@example_author` or +`git@example_committer` instead of `git@example.org` (e.g., `git remote set-url +git@example_author:org1/project1.git`). + +Common Issues +------------- + +[[last-commit-amend]] +I've made a mistake in the last commit. How do I change it?:: + You can make the appropriate change to your working tree, run `git add + <file>` or `git rm <file>`, as appropriate, to stage it, and then `git + commit --amend`. Your change will be included in the commit, and you'll + be prompted to edit the commit message again; if you wish to use the + original message verbatim, you can use the `--no-edit` option to `git + commit` in addition, or just save and quit when your editor opens. + +[[undo-previous-change]] +I've made a change with a bug and it's been included in the main branch. How should I undo it?:: + The usual way to deal with this is to use `git revert`. This preserves + the history that the original change was made and was a valuable + contribution, but also introduces a new commit that undoes those changes + because the original had a problem. The commit message of the revert + indicates the commit which was reverted and is usually edited to include + an explanation as to why the revert was made. + +[[ignore-tracked-files]] +How do I ignore changes to a tracked file?:: + Git doesn't provide a way to do this. The reason is that if Git needs + to overwrite this file, such as during a checkout, it doesn't know + whether the changes to the file are precious and should be kept, or + whether they are irrelevant and can safely be destroyed. Therefore, it + has to take the safe route and always preserve them. ++ +It's tempting to try to use certain features of `git update-index`, namely the +assume-unchanged and skip-worktree bits, but these don't work properly for this +purpose and shouldn't be used this way. ++ +If your goal is to modify a configuration file, it can often be helpful to have +a file checked into the repository which is a template or set of defaults which +can then be copied alongside and modified as appropriate. This second, modified +file is usually ignored to prevent accidentally committing it. + +Hooks +----- + +[[restrict-with-hooks]] +How do I use hooks to prevent users from making certain changes?:: + The only safe place to make these changes is on the remote repository + (i.e., the Git server), usually in the `pre-receive` hook or in a + continuous integration (CI) system. These are the locations in which + policy can be enforced effectively. ++ +It's common to try to use `pre-commit` hooks (or, for commit messages, +`commit-msg` hooks) to check these things, which is great if you're working as a +solo developer and want the tooling to help you. However, using hooks on a +developer machine is not effective as a policy control because a user can bypass +these hooks with `--no-verify` without being noticed (among various other ways). +Git assumes that the user is in control of their local repositories and doesn't +try to prevent this or tattle on the user. ++ +In addition, some advanced users find `pre-commit` hooks to be an impediment to +workflows that use temporary commits to stage work in progress or that create +fixup commits, so it's better to push these kinds of checks to the server +anyway. + +Cross-Platform Issues +--------------------- + +[[windows-text-binary]] +I'm on Windows and my text files are detected as binary.:: + Git works best when you store text files as UTF-8. Many programs on + Windows support UTF-8, but some do not and only use the little-endian + UTF-16 format, which Git detects as binary. If you can't use UTF-8 with + your programs, you can specify a working tree encoding that indicates + which encoding your files should be checked out with, while still + storing these files as UTF-8 in the repository. This allows tools like + linkgit:git-diff[1] to work as expected, while still allowing your tools + to work. ++ +To do so, you can specify a linkgit:gitattributes[5] pattern with the +`working-tree-encoding` attribute. For example, the following pattern sets all +C files to use UTF-16LE-BOM, which is a common encoding on Windows: ++ +---- +*.c working-tree-encoding=UTF-16LE-BOM +---- ++ +You will need to run `git add --renormalize` to have this take effect. Note +that if you are making these changes on a project that is used across platforms, +you'll probably want to make it in a per-user configuration file or in the one +in `$GIT_DIR/info/attributes`, since making it in a `.gitattributes` file in the +repository will apply to all users of the repository. ++ +See the following entry for information about normalizing line endings as well, +and see linkgit:gitattributes[5] for more information about attribute files. + +[[windows-diff-control-m]] +I'm on Windows and git diff shows my files as having a `^M` at the end.:: + By default, Git expects files to be stored with Unix line endings. As such, + the carriage return (`^M`) that is part of a Windows line ending is shown + because it is considered to be trailing whitespace. Git defaults to showing + trailing whitespace only on new lines, not existing ones. ++ +You can store the files in the repository with Unix line endings and convert +them automatically to your platform's line endings. To do that, set the +configuration option `core.eol` to `native` and see the following entry for +information about how to configure files as text or binary. ++ +You can also control this behavior with the `core.whitespace` setting if you +don't wish to remove the carriage returns from your line endings. + +[[recommended-storage-settings]] +What's the recommended way to store files in Git?:: + While Git can store and handle any file of any type, there are some + settings that work better than others. In general, we recommend that + text files be stored in UTF-8 without a byte-order mark (BOM) with LF + (Unix-style) endings. We also recommend the use of UTF-8 (again, + without BOM) in commit messages. These are the settings that work best + across platforms and with tools such as `git diff` and `git merge`. ++ +Additionally, if you have a choice between storage formats that are text based +or non-text based, we recommend storing files in the text format and, if +necessary, transforming them into the other format. For example, a text-based +SQL dump with one record per line will work much better for diffing and merging +than an actual database file. Similarly, text-based formats such as Markdown +and AsciiDoc will work better than binary formats such as Microsoft Word and +PDF. ++ +Similarly, storing binary dependencies (e.g., shared libraries or JAR files) or +build products in the repository is generally not recommended. Dependencies and +build products are best stored on an artifact or package server with only +references, URLs, and hashes stored in the repository. ++ +We also recommend setting a linkgit:gitattributes[5] file to explicitly mark +which files are text and which are binary. If you want Git to guess, you can +set the attribute `text=auto`. For example, the following might be appropriate +in some projects: ++ +---- +# By default, guess. +* text=auto +# Mark all C files as text. +*.c text +# Mark all JPEG files as binary. +*.jpg binary +---- ++ +These settings help tools pick the right format for output such as patches and +result in files being checked out in the appropriate line ending for the +platform. + +GIT +--- +Part of the linkgit:git[1] suite diff --git a/Documentation/githooks.txt b/Documentation/githooks.txt index 3dccab5375..81f2a87e88 100644 --- a/Documentation/githooks.txt +++ b/Documentation/githooks.txt @@ -522,12 +522,61 @@ The exit status determines whether git will use the data from the hook to limit its search.

The single-parent commits `C`, `Z`, +and `Y` do not change `file.txt`. The merge commit `M` was created by +resolving the merge conflict to include both changes from `A` and `B` +and hence is not TREESAME to either. The merge commit `R`, however, was +created by ignoring the contents of `file.txt` at `M` and taking only +the contents of `file.txt` at `X`. Hence, `R` is TREESAME to `X` but not +`M`. Finally, the natural merge resolution to create `N` is to take the +contents of `file.txt` at `R`, so `N` is TREESAME to `R` but not `C`. +The merge commits `O` and `P` are TREESAME to their first parents, but +not to their second parents, `Z` and `Y` respectively. ++ +When using the default mode, `N` and `R` both have a TREESAME parent, so +those edges are walked and the others are ignored. The resulting history +graph is: ++ +----------------------------------------------------------------------- + I---X +----------------------------------------------------------------------- ++ +When using `--full-history`, Git walks every edge. This will discover +the commits `A` and `B` and the merge `M`, but also will reveal the +merge commits `O` and `P`. With parent rewriting, the resulting graph is: ++ +----------------------------------------------------------------------- + .-A---M--------N---O---P + / / \ \ \/ / / + I B \ R-'`--' / + \ / \/ / + \ / /\ / + `---X--' `------' +----------------------------------------------------------------------- ++ +Here, the merge commits `O` and `P` contribute extra noise, as they did +not actually contribute a change to `file.txt`. They only merged a topic +that was based on an older version of `file.txt`. This is a common +issue in repositories using a workflow where many contributors work in +parallel and merge their topic branches along a single trunk: manu +unrelated merges appear in the `--full-history` results. ++ +When using the `--simplify-merges` option, the commits `O` and `P` +disappear from the results. This is because the rewritten second parents +of `O` and `P` are reachable from their first parents. Those edges are +removed and then the commits look like single-parent commits that are +TREESAME to their parent. This also happens to the commit `N`, resulting +in a history view as follows: ++ +----------------------------------------------------------------------- + .-A---M--. + / / \ + I B R + \ / / + \ / / + `---X--' +----------------------------------------------------------------------- ++ +In this view, we see all of the important single-parent changes from +`A`, `B`, and `X`. We also see the carefully-resolved merge `M` and the +not-so-carefully-resolved merge `R`. This is usually enough information +to determine why the commits `A` and `B` "disappeared" from history in +the default view. However, there are a few issues with this approach. ++ +The first issue is performance. Unlike any previous option, the +`--simplify-merges` option requires walking the entire commit history +before returning a single result. This can make the option difficult to +use for very large repositories. ++ +The second issue is one of auditing. When many contributors are working +on the same repository, it is important which merge commits introduced +a change into an important branch. The problematic merge `R` above is +not likely to be the merge commit that was used to merge into an +important branch. Instead, the merge `N` was used to merge `R` and `X` +into the important branch. This commit may have information about why +the change `X` came to override the changes from `A` and `B` in its +commit message. ++ +The `--show-pulls` option helps with both of these issues by adding more +merge commits to the history results. If a merge is not TREESAME to its +first parent but is TREESAME to a later parent, then that merge is +treated as if it "pulled" the change from another branch. When using +`--show-pulls` on this example (and no other options) the resulting +graph is: ++ +----------------------------------------------------------------------- + I---X---R---N +----------------------------------------------------------------------- ++ +Here, the merge commits `R` and `N` are included because they pulled +the commits `X` and `R` into the base branch, respectively. These +merges are the reason the commits `A` and `B` do not appear in the +default history. ++ +When `--show-pulls` is paired with `--simplify-merges`, the +graph includes all of the necessary information: ++ +----------------------------------------------------------------------- + .-A---M--. N + / / \ / + I B R + \ / / + \ / / + `---X--' +----------------------------------------------------------------------- ++ +Notice that since `M` is reachable from `R`, the edge from `N` to `M` +was simplified away. However, `N` still appears in the history as an +important commit because it "pulled" the change `R` into the main +branch. + The `--simplify-by-decoration` option allows you to view only the big picture of the topology of the history, by omitting commits that are not referenced by tags.
