2022-08-10advice.h: add advise_on_moving_dirty_path()Shaoxuan Yuan
Add an advice. When the user use `git mv --sparse <dirty-path> <destination>`, Git will warn the user to use `git add --sparse <paths>` then use `git sparse-checkout reapply` to apply the sparsity rules. Add a few lines to previous "move dirty path" tests so we can test this new advice is working.

2022-04-04Merge branch 'tk/ambiguous-fetch-refspec'Junio C Hamano
Give hint when branch tracking cannot be established because fetch refspecs from multiple remote repositories overlap. * tk/ambiguous-fetch-refspec: tracking branches: add advice to ambiguous refspec error
2022-04-01tracking branches: add advice to ambiguous refspec errorTao Klerks
The error "not tracking: ambiguous information for ref" is raised when we are evaluating what tracking information to set on a branch, and find that the ref to be added as tracking branch is mapped under multiple remotes' fetch refspecs. This can easily happen when a user copy-pastes a remote definition in their git config, and forgets to change the tracking path. Add advice in this situation, explicitly highlighting which remotes are involved and suggesting how to correct the situation. Also update a test to explicitly expect that advice.

2022-03-15reset: replace '--quiet' with '--no-refresh' in performance adviceVictoria Dye
Replace references to '--quiet' with '--no-refresh' in the advice on how to skip refreshing the index. When the advice was introduced, '--quiet' was the only way to avoid the expensive 'refresh_index(...)' at the end of a mixed reset. After introducing '--no-refresh', however, '--quiet' became only a fallback option for determining refresh behavior, overridden by '--[no-]refresh' or 'reset.refresh' if either is set. To ensure users are advised to use the most reliable option for avoiding 'refresh_index(...)', replace recommendation of '--quiet' with '--[no-]refresh'.

2022-02-04branch: add --recurse-submodules option for branch creationGlen Choo
To improve the submodules UX, we would like to teach Git to handle branches in submodules. Start this process by teaching "git branch" the --recurse-submodules option so that "git branch --recurse-submodules topic" will create the `topic` branch in the superproject and its submodules. Although this commit does not introduce breaking changes, it does not work well with existing --recurse-submodules commands because "git branch --recurse-submodules" writes to the submodule ref store, but most commands only consider the superproject gitlink and ignore the submodule ref store. For example, "git checkout --recurse-submodules" will check out the commits in the superproject gitlinks (and put the submodules in detached HEAD) instead of checking out the submodule branches. Because of this, this commit introduces a new configuration value, `submodule.propagateBranches`. The plan is for Git commands to prioritize submodule ref store information over superproject gitlinks if this value is true. Because "git branch --recurse-submodules" writes to submodule ref stores, for the sake of clarity, it will not function unless this configuration value is set. This commit also includes changes that support working with submodules from a superproject commit because "branch --recurse-submodules" (and future commands) need to read .gitmodules and gitlinks from the superproject commit, but submodules are typically read from the filesystem's .gitmodules and the index's gitlinks. These changes are: * add a submodules_of_tree() helper that gives the relevant information of an in-tree submodule (e.g. path and oid) and initializes the repository * add is_tree_submodule_active() by adding a treeish_name parameter to is_submodule_active() * add the "submoduleNotUpdated" advice to advise users to update the submodules in their trees Incidentally, fix an incorrect usage string that combined the 'list' usage of git branch (-l) with the 'create' usage; this string has been incorrect since its inception, a8dfd5eac4 (Make builtin-branch.c use parse_options., 2007-10-07).

Note that we only warn the user whey they give a pathspec item that matches no eligible path for updating, but it does match one or more SKIP_WORKTREE entries.

The previous commit added the necessary machinery to implement the "--force-if-includes" protection, when "--force-with-lease" is used without giving exact object the remote still ought to have. Surface the feature by adding a command line option and a configuration variable to enable it. - Add a flag: "TRANSPORT_PUSH_FORCE_IF_INCLUDES" to indicate that the new option was passed from the command line of via configuration settings; update command line and configuration parsers to set the new flag accordingly. - Introduce a new configuration option "push.useForceIfIncludes", which is equivalent to setting "--force-if-includes" in the command line. - Update "remote-curl" to recognize and pass this option to "send-pack" when enabled. - Update "advise" to catch the reject reason "REJECT_REF_NEEDS_UPDATE", set when the ref status is "REF_STATUS_REJECT_REMOTE_UPDATED" and (optionally) print a help message when the push fails. - The new option is a "no-op" in the following scenarios: * When used without "--force-with-lease". * When used with "--force-with-lease", and if the expected commit on the remote side is specified as an argument.

Add a new helper advise_enabled to check the visibility of the advice if the caller needs to carry out complicated processing based on that value.

2018-06-11checkout: add advice for ambiguous "checkout <branch>"Ævar Arnfjörð Bjarmason
As the "checkout" documentation describes: If <branch> is not found but there does exist a tracking branch in exactly one remote (call it <remote>) with a matching name, treat as equivalent to [...] <remote>/<branch. This is a really useful feature. The problem is that when you add another remote (e.g. a fork), git won't find a unique branch name anymore, and will instead print this unhelpful message: $ git checkout master error: pathspec 'master' did not match any file(s) known to git Now it will, on my git.git checkout, print: $ ./git --exec-path=$PWD checkout master error: pathspec 'master' did not match any file(s) known to git. hint: 'master' matched more than one remote tracking branch. hint: We found 26 remotes with a reference that matched. So we fell back hint: on trying to resolve the argument as a path, but failed there too! hint: hint: If you meant to check out a remote tracking branch on, e.g. 'origin', hint: you can do so by fully qualifying the name with the --track option: hint: hint: git checkout --track origin/<name> Note that the "error: pathspec[...]" message is still printed. This is because whatever else checkout may have tried earlier, its final fallback is to try to resolve the argument as a path. E.g. in this case: $ ./git --exec-path=$PWD checkout master pu error: pathspec 'master' did not match any file(s) known to git. error: pathspec 'pu' did not match any file(s) known to git. There we don't print the "hint:" implicitly due to earlier logic around the DWIM fallback. That fallback is only used if it looks like we have one argument that might be a branch. I can't think of an intrinsic reason for why we couldn't in some future change skip printing the "error: pathspec[...]" error. However, to do so we'd need to pass something down to checkout_paths() to make it suppress printing an error on its own, and for us to be confident that we're not silencing cases where those errors are meaningful. I don't think that's worth it since determining whether that's the case could easily change due to future changes in the checkout logic.

2018-04-30Deprecate support for .git/info/graftsJohannes Schindelin
The grafts feature was a convenient way to "stitch together" ancient history to the fresh start of linux.git. Its implementation is, however, not up to Git's standards, as there are too many ways where it can lead to surprising and unwelcome behavior. For example, when pushing from a repository with active grafts, it is possible to miss commits that have been "grafted out", resulting in a broken state on the other side. Also, the grafts feature is limited to "rewriting" commits' list of parents, it cannot replace anything else. The much younger feature implemented as `git replace` set out to remedy those limitations and dangerous bugs. Seeing as `git replace` is pretty mature by now (since 4228e8bc98 (replace: add --graft option, 2014-07-19) it can perform the graft file's duties), it is time to deprecate support for the graft file, and to retire it eventually.

When a graphical GIT_EDITOR is spawned by a Git command that opens and waits for user input (e.g. "git rebase -i"), then the editor window might be obscured by other windows. The user might be left staring at the original Git terminal window without even realizing that s/he needs to interact with another window before Git can proceed. To this user Git appears hanging. Print a message that Git is waiting for editor input in the original terminal and get rid of it when the editor returns, if the terminal supports erasing the last line. Also, make sure that our message is terminated with a whitespace so that any message the editor may show upon starting up will be kept separate from our message. Power users might not want to see this message or their editor might already print such a message (e.g. emacsclient). Allow these users to suppress the message by disabling the "advice.waitingForEditor" config.

When an hook is present but the file is not set as executable then git will ignore the hook. For now this is silent which can be confusing. This commit adds this warning to improve the situation: hint: The 'pre-commit' hook was ignored because it's not set as executable. hint: You can disable this warning with `git config advice.ignoredHook false` To allow the old use-case of enabling/disabling hooks via the executable flag a new setting is introduced: advice.ignoredHook.

2017-06-15add: warn when adding an embedded repositoryJeff King
It's an easy mistake to add a repository inside another repository, like: git clone $url git add . The resulting entry is a gitlink, but there's no matching .gitmodules entry. Trying to use "submodule init" (or clone with --recursive) doesn't do anything useful. Prior to v2.13, such an entry caused git-submodule to barf entirely. In v2.13, the entry is considered "inactive" and quietly ignored. Either way, no clone of your repository can do anything useful with the gitlink without the user manually adding the submodule config. In most cases, the user probably meant to either add a real submodule, or they forgot to put the embedded repository in their .gitignore file. Let's issue a warning when we see this case. There are a few things to note: - the warning will go in the git-add porcelain; anybody wanting to do low-level manipulation of the index is welcome to create whatever funny states they want. - we detect the case by looking for a newly added gitlink; updates via "git add submodule" are perfectly reasonable, and this avoids us having to investigate .gitmodules entirely - there's a command-line option to suppress the warning. This is needed for git-submodule itself (which adds the entry before adding any submodule config), but also provides a mechanism for other scripts doing submodule-like things. We could make this a hard error instead of a warning. However, we do add lots of sub-repos in our test suite. It's not _wrong_ to do so. It just creates a state where users may be surprised. Pointing them in the right direction with a gentle hint is probably the best option. There is a config knob that can disable the (long) hint. But I intentionally omitted a config knob to disable the warning entirely. Whether the warning is sensible or not is generally about context, not about the user's preferences. If there's a tool or workflow that adds gitlinks without matching .gitmodules, it should probably be taught about the new command-line option, rather than blanket-disabling the warning.

2015-06-18pull: check if in unresolved merge statePaul Tan
Since d38a30d (Be more user-friendly when refusing to do something because of conflict., 2010-01-12), git-pull will error out with user-friendly advices if the user is in the middle of a merge or has unmerged files. Re-implement this behavior. While the "has unmerged files" case can be handled by die_resolve_conflict(), we introduce a new function die_conclude_merge() for printing a different error message for when there are no unmerged files but the merge has not been finished.

Use the function attributes extension to catch mistakes in use of our own variadic functions that use NULL sentinel at the end (i.e. like execl(3)) and format strings (i.e. like printf(3)). * jk/gcc-function-attributes: Add the LAST_ARG_MUST_BE_NULL macro wt-status: use "format" function attribute for status_printf use "sentinel" function attribute for variadic lists add missing "format" function attributes
2013-07-10add missing "format" function attributesJeff King
For most of our functions that take printf-like formats, we use gcc's __attribute__((format)) to get compiler warnings when the functions are misused. Let's give a few more functions the same protection. In most cases, the annotations do not uncover any actual bugs; the only code change needed is that we passed a size_t to transfer_debug, which expected an int. Since we expect the passed-in value to be a relatively small buffer size (and cast a similar value to int directly below), we can just cast away the problem.

We promised to change the behaviour of lazy "git push [there]" that does not say what to push on the command line from "matching" to "simple" in Git 2.0. This finally flips that bit. Helped-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-06-12rm: introduce advice.rmHints to shorten messagesMathieu Lienard--Mayor
Introduce advice.rmHints to choose whether to display advice or not when git rm fails. Defaults to true, in order to preserve current behavior. As an example, the message: error: 'foo.txt' has changes staged in the index (use --cached to keep the file, or -f to force removal) would look like, with advice.rmHints=false: error: 'foo.txt' has changes staged in the index Signed-off-by: Mathieu Lienard--Mayor <Mathieu.Lienard--Mayor@ensimag.imag.fr> Signed-off-by: Jorge Juan Garcia Garcia <Jorge-Juan.Garcia-Garcia@ensimag.imag.fr> Signed-off-by: Matthieu Moy <Matthieu.Moy@grenoble-inp.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-06-11Merge branch 'nd/warn-ambiguous-object-name'Junio C Hamano
"git cmd <name>", when <name> happens to be a 40-hex string, directly uses the 40-hex string as an object name, even if a ref "refs/<some hierarchy>/<name>" exists. This disambiguation order is unlikely to change, but we should warn about the ambiguity just like we warn when more than one refs/ hierachies share the same name. * nd/warn-ambiguous-object-name: get_sha1: warn about full or short object names that look like refs
