2025-09-16color: use git_colorbool enum type to store colorboolsJeff King1-1/+1
We traditionally used "int" to store and pass around the values defined by "enum git_colorbool" (which were originally just #define macros). Using an int doesn't produce incorrect results, but using the actual enum makes the intent of the code more clear. It would be nice if the compiler could catch cases where we used the enum and an int interchangeably, since it's very easy to accidentally check the boolean true/false of a colorbool like: if (branch_use_color) This is wrong because GIT_COLOR_UNKNOWN and GIT_COLOR_AUTO evaluate to true in C, even though we may ultimately decide not to use color. But C is pretty happy to convert between ints and enums (even with various -Wenum-* warnings). So this sadly doesn't protect us from such mistakes, but it hopefully does make the code easier to read.

2025-09-16color: use GIT_COLOR_* instead of numeric constantsJeff King1-1/+1
Long ago Git's decision to show color for a subsytem was stored in a tri-state variable: it could be true (1), false (0), or unknown (-1). But since daa0c3d971 (color: delay auto-color decision until point of use, 2011-08-17) we want to carry around a new state, "auto", which bases the decision on the tty-ness of stdout (rather than collapsing that "auto" state to a true/false immediately). That commit introduced a set of GIT_COLOR_* defines to represent each state: UNKNOWN, ALWAYS, NEVER, and AUTO. But it only used the AUTO value, and left alone code using bare 0/1/-1 values. And of course since then we've grown many new spots that use those bare values. Let's switch all of these to use the named constants. That should make the code a bit easier to read, as it is more obvious that we're representing a color decision.

In this scenario, the advice message is always shown even if the `--no-advice` option is used.

2024-12-06global: trivial conversions to fix `-Wsign-compare` warningsPatrick Steinhardt1-7/+2
We have a bunch of loops which iterate up to an unsigned boundary using a signed index, which generates warnigs because we compare a signed and unsigned value in the loop condition.

2024-07-16Merge branch 'ds/advice-sparse-index-expansion'Junio C Hamano1-0/+1
A new warning message is issued when a command has to expand a sparse index to handle working tree cruft that are outside of the sparse checkout. * ds/advice-sparse-index-expansion: advice: warn when sparse index expands
2024-07-08advice: warn when sparse index expandsDerrick Stolee1-0/+1
Typically, forcing a sparse index to expand to a full index means that Git could not determine the status of a file outside of the sparse-checkout and needed to expand sparse trees into the full list of sparse blobs. This operation can be very slow when the sparse-checkout is much smaller than the full tree at HEAD. When users are in this state, there is usually a modified or untracked file outside of the sparse-checkout mentioned by the output of 'git status'. There are a number of reasons why this is insufficient: 1. Users may not have a full understanding of which files are inside or outside of their sparse-checkout. This is more common in monorepos that manage the sparse-checkout using custom tools that map build dependencies into sparse-checkout definitions. 2. In some cases, an empty directory could exist outside the sparse-checkout and these empty directories are not reported by 'git status' and friends. 3. If the user has '.gitignore' or 'exclude' files, then 'git status' will squelch the warnings and not demonstrate any problems. In order to help users who are in this state, add a new advice message to indicate that a sparse index is expanded to a full index. This message should be written at most once per process, so add a static global 'give_advice_on_expansion' to sparse-index.c. Further, there is a case in 'git sparse-checkout set' that uses the sparse index as an in-memory data structure (even when writing a full index) so we need to disable the message in that kind of case. The t1092-sparse-checkout-compatibility.sh test script compares the behavior of several Git commands across full and sparse repositories, including sparse repositories with and without a sparse index. We need to disable the advice in the sparse-index repo to avoid differences in stderr. By leaving the advice on in the sparse-checkout repo (without the sparse index), we can test the behavior of disabling the advice in convert_to_sparse(). (Indeed, these tests are how that necessity was discovered.) Add a test that reenables the advice and demonstrates that the message is output. The advice message is defined outside of expand_index() to avoid super- wide lines. It is also defined as a macro to avoid compile issues with -Werror=format-security.

2024-06-20Merge branch 'pw/rebase-i-error-message'Junio C Hamano1-0/+1
When the user adds to "git rebase -i" instruction to "pick" a merge commit, the error experience is not pleasant. Such an error is now caught earlier in the process that parses the todo list. * pw/rebase-i-error-message: rebase -i: improve error message when picking merge rebase -i: pass struct replay_opts to parse_insn_line()
2024-05-30rebase -i: improve error message when picking mergePhillip Wood1-0/+1
The only todo commands that accept a merge commit are "merge" and "reset". All the other commands like "pick" or "reword" fail when they try to pick a a merge commit and print the message error: commit abc123 is a merge but no -m option was given. followed by a hint about the command being rescheduled. This message is designed to help the user when they cherry-pick a merge and forget to pass "-m". For users who are rebasing the message is confusing as there is no way for rebase to cherry-pick the merge. Improve the user experience by detecting the error and printing some advice on how to fix it when the todo list is parsed rather than waiting for the "pick" command to fail. The advice recommends "merge" rather than "exec git cherry-pick -m ..." on the assumption that cherry-picking merges is relatively rare and it is more likely that the user chose "pick" by a mistake. It would be possible to support cherry-picking merges by allowing the user to pass "-m" to "pick" commands but that adds complexity to do something that can already be achieved with exec git cherry-pick -m1 abc123 Reported-by: Stefan Haller <lists@haller-berlin.de> Signed-off-by: Phillip Wood <phillip.wood@dunelm.org.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2024-05-03advice: add --no-advice global optionJames Liu1-0/+7
Advice hints must be disabled individually by setting the relevant advice.* variables to false in the Git configuration. For server-side and scripted usages of Git where hints can be a hindrance, it can be cumbersome to maintain configuration to ensure all advice hints are disabled in perpetuity. This is a particular concern in tests, where new or changed hints can result in failed assertions. Add a --no-advice global option to disable all advice hints from being displayed. This is independent of the toggles for individual advice hints. Use an internal environment variable (GIT_ADVICE) to ensure this configuration is propagated to the usage site, even if it executes in a subprocess.

2024-03-29advice: omit trailing whitespaceJunio C Hamano1-1/+2
Git tools all consistently encourage users to avoid whitespaces at the end of line by giving them features like "git diff --check" and "git am --whitespace=fix". Make sure that the advice messages we give users avoid trailing whitespaces. We shouldn't be wasting vertical screen real estate by adding blank lines in advice messages that are supposed to be concise hints, but as long as we write such blank line in our "hints", we should do it right. A test that expects the current behaviour of leaving trailing whitespaces has been adjusted. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2024-03-18sequencer: allow disabling conflict advicePhilippe Blain1-0/+1
Allow disabling the advice shown when a squencer operation results in a merge conflict through a new config 'advice.mergeConflict', which is named generically such that it can be used by other commands eventually. Remove that final '\n' in the first hunk in sequencer.c to avoid an otherwise empty 'hint: ' line before the line 'hint: Disable this message with "git config advice.mergeConflict false"' which is automatically added by 'advise_if_enabled'. Note that we use 'advise_if_enabled' for each message in the second hunk in sequencer.c, instead of using 'if (show_hints && advice_enabled(...)', because the former instructs the user how to disable the advice, which is more user-friendly. Update the tests accordingly. Note that the body of the second test in t3507-cherry-pick-conflict.sh is enclosed in double quotes, so we must escape them in the added line. Note that t5520-pull.sh, which checks that we display the advice for 'git rebase' (via 'git pull --rebase') does not have to be updated because it only greps for a specific line in the advice message.

2023-08-07advice: handle "rebase" in error_resolve_conflict()Oswald Buddenhagen1-2/+3
This makes sure that we get a properly translated message rather than inserting the command (which we failed to translate) into a generic fallback message. The function is called indirectly via die_resolve_conflict() with fixed strings, and directly with the string obtained via action_name(), which in turn returns a string from a fixed set. Hence we know that the now covered set of strings is exhausitive, and will therefore BUG() out when encountering an unexpected string. We also know that all covered strings are actually used. Arguably, the above suggests that it would be cleaner to pass the command as an enum in the first place, but that's left for another time.

2022-02-04branch: add --recurse-submodules option for branch creationGlen Choo1-0/+1
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).

See 8821e90a09a (advice: don't pointlessly suggest --convert-graft-file, 2018-11-27) for why quieting this advice was needed. It's more straightforward to move this code to commit.[ch] and use it builtin/replace.c, than to go through the indirection of advice.[ch]. Because this was the last advice_config variable we can remove that old facility from advice.c.

In c4a09cc9ccb (Merge branch 'hw/advise-ng', 2020-03-25), a new API for accessing advice variables was introduced and deprecated `advice_config` in favor of a new array, `advice_setting`. This patch ports all but two uses which read the status of the global `advice_` variables over to the new `advice_enabled` API.

In daef1b300b0 (Merge branch 'hw/advice-add-nothing', 2020-02-14), two advice settings were introduced into the `advice_config` array. Subsequently, c4a09cc9ccb (Merge branch 'hw/advise-ng', 2020-03-25) started to deprecate `advice_config` in favor of a new array, `advice_setting`. However, the latter branch did not include the former branch, and therefore `advice_setting` is missing the two entries added by the `hw/advice-add-nothing` branch. These are currently the only entries in `advice_config` missing from `advice_setting`.

2021-04-08add: warn when asked to update SKIP_WORKTREE entriesMatheus Tavares1-0/+20
`git add` already refrains from updating SKIP_WORKTREE entries, but it silently exits with zero code when it is asked to do so. Instead, let's warn the user and display a hint on how to update these entries. 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. A warning was chosen over erroring out right away to reproduce the same behavior `add` already exhibits with ignored files. This also allow users to continue their workflow without having to invoke `add` again with only the eligible paths (as those will have already been added).

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.

Currently it's very easy for the advice library's callers to miss checking the visibility step before printing an advice. Also, it makes more sense for this step to be handled by the advice library. Add a new advise_if_enabled function that checks the visibility of advice messages before printing. 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. A list of advice_settings is added to cache the config variables names and values, it's intended to replace advice_config[] and the global variables once we migrate all the callers to use the new APIs.

2018-06-11checkout: add advice for ambiguous "checkout <branch>"Ævar Arnfjörð Bjarmason1-0/+2
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 Schindelin1-0/+2
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.

This is an attempt to resolve an issue I experience with people that are new to Git -- especially colleagues in a team setting -- where they miss that their push to a remote location failed because the failure and success both return a block of white text. An example is if I push something to a remote repository and then a colleague attempts to push to the same remote repository and the push fails because it requires them to pull first, but they don't notice because a success and failure both return a block of white text. They then continue about their business, thinking it has been successfully pushed.

2017-12-07launch_editor(): indicate that Git waits for user inputLars Schneider1-0/+2
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. The standard advise() function is not used here as it would always add a newline which would make deleting the message harder.

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.

Mark message for translation telling the user she has conflicts to resolve. Expose each particular use case, in order to enable translating entire sentences which would facilitate translating into other languages. Change "Pull" to lowercase to match other instances. Update test t5520-pull.sh, that relied on the old error message, to use the new one.

2014-08-28merge, pull: stop advising 'commit -a' in case of conflictMatthieu Moy1-2/+1
'git commit -a' is rarely a good way to mark conflicts as resolved: the user anyway has to go manually through the list of conflicts to do the actual resolution, and it is usually better to use "git add" on each files after doing the resolution. On the other hand, using 'git commit -a' is potentially dangerous, as it makes it very easy to mistakenly commit conflict markers without noticing, and even worse, the user may have started a merge while having local changes that do not overlap with it in the working tree. While we're there, synchronize the 'git pull' and 'git merge' messages: the first was ending with '... and make a commit.', but not the latter. Eventually, git should detect that conflicts have been resolved in the working tree and tailor these messages further. Not only "use git commit -a" could be resurected, but "Fix them up in the work tree" should be dropped when it happens.

2014-06-20refactor skip_prefix to return a booleanJeff King1-1/+4
The skip_prefix() function returns a pointer to the content past the prefix, or NULL if the prefix was not found. While this is nice and simple, in practice it makes it hard to use for two reasons: 1. When you want to conditionally skip or keep the string as-is, you have to introduce a temporary variable. For example: tmp = skip_prefix(buf, "foo"); if (tmp) buf = tmp; 2. It is verbose to check the outcome in a conditional, as you need extra parentheses to silence compiler warnings. For example: if ((cp = skip_prefix(buf, "foo")) /* do something with cp */ Both of these make it harder to use for long if-chains, and we tend to use starts_with() instead. However, the first line of "do something" is often to then skip forward in buf past the prefix, either using a magic constant or with an extra strlen(3) (which is generally computed at compile time, but means we are repeating ourselves). This patch refactors skip_prefix() to return a simple boolean, and to provide the pointer value as an out-parameter. If the prefix is not found, the out-parameter is untouched. This lets you write: if (skip_prefix(arg, "foo ", &arg)) do_foo(arg); else if (skip_prefix(arg, "bar ", &arg)) do_bar(arg); Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-06-03error_resolve_conflict: drop quotations around operationJeff King1-1/+1
When you try to commit with unmerged entries, you get an error like: $ git commit error: 'commit' is not possible because you have unmerged files. The quotes around "commit" are clunky; the user doesn't care that this message is a template with the command-name filled in. Saying: error: commit is not possible because you have unmerged files is easier to read. As this code is called from other places, we may also end up with: $ git merge error: merge is not possible because you have unmerged files $ git cherry-pick foo error: cherry-pick is not possible because you have unmerged files $ git revert foo error: revert is not possible because you have unmerged files All of which look better without the quotes. This also happens to match the behavior of "git pull", which generates a similar message (but does not share code, as it is a shell script).

2013-01-24push: introduce REJECT_FETCH_FIRST and REJECT_NEEDS_FORCEJunio C Hamano1-0/+4
When we push to update an existing ref, if: * the object at the tip of the remote is not a commit; or * the object we are pushing is not a commit, it won't be correct to suggest to fetch, integrate and push again, as the old and new objects will not "merge". We should explain that the push must be forced when there is a non-committish object is involved in such a case. If we do not have the current object at the tip of the remote, we do not even know that object, when fetched, is something that can be merged. In such a case, suggesting to pull first just like non-fast-forward case may not be technically correct, but in practice, most such failures are seen when you try to push your work to a branch without knowing that somebody else already pushed to update the same branch since you forked, so "pull first" would work as a suggestion most of the time. And if the object at the tip is not a commit, "pull first" will fail, without making any permanent damage. As a side effect, it also makes the error message the user will get during the next "push" attempt easier to understand, now the user is aware that a non-commit object is involved. In these cases, the current code already rejects such a push on the client end, but we used the same error and advice messages as the ones used when rejecting a non-fast-forward push, i.e. pull from there and integrate before pushing again. Introduce new rejection reasons and reword the messages appropriately. [jc: with help by Peff on message details] Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-03-19push: Provide situational hints for non-fast-forward errorsChristopher Tiwald1-0/+6
Pushing a non-fast-forward update to a remote repository will result in an error, but the hint text doesn't provide the correct resolution in every case. Give better resolution advice in three push scenarios: 1) If you push your current branch and it triggers a non-fast-forward error, you should merge remote changes with 'git pull' before pushing again. 2) If you push to a shared repository others push to, and your local tracking branches are not kept up to date, the 'matching refs' default will generate non-fast-forward errors on outdated branches. If this is your workflow, the 'matching refs' default is not for you. Consider setting the 'push.default' configuration variable to 'current' or 'upstream' to ensure only your current branch is pushed. 3) If you explicitly specify a ref that is not your current branch or push matching branches with ':', you will generate a non-fast-forward error if any pushed branch tip is out of date. You should checkout the offending branch and merge remote changes before pushing again. Teach transport.c to recognize these scenarios and configure push.c to hint for them. If 'git push's default behavior changes or we discover more scenarios, extension is easy. Standardize on the advice API and add three new advice variables, 'pushNonFFCurrent', 'pushNonFFDefault', and 'pushNonFFMatching'. Setting any of these to 'false' will disable their affiliated advice. Setting 'pushNonFastForward' to false will disable all three, thus preserving the config option for users who already set it, but guaranteeing new users won't disable push advice accidentally.

Advice messages are by definition meant for human end-users, and prime candidates for i18n/l10n. They tend to also be more verbose to be helpful, and need to be longer than just one line. Although we do not have parameterized multi-line advice messages yet, once we do, we cannot emit such a message like this: advise(_("Please rename %s to something else"), gostak); advise(_("so that we can avoid distimming %s unnecessarily."), doshes); because some translations may need to have the replacement of 'gostak' on the second line (or 'doshes' on the first line). Some languages may even need to use three lines in order to fit the same message within a reasonable width. Instead, it has to be a single advise() construct, like this: advise(_("Please rename %s to something else\n" "so that we can avoid distimming %s unnecessarily."), gostak, doshes); Update the advise() function and its existing callers to - take a format string that can be multi-line and translatable as a whole; - use the string and the parameters to form a localized message; and - show each line in the result with the localization of the "hint: ".

The old "advice" message explained how to create a branch after going into a detached HEAD state but didn't make it clear why the user may want to do so. Also "moving to ... which isn't a local branch" was unclear if it is complaining, if it is describing the new state, or if it is explaining why the HEAD is detached (the true reason is the last one). Give the established phrase 'detached HEAD' first to make it easy for users to look up the concept in documentation, and briefly describe what can be done in the state (i.e. play around without having to clean up) before telling the user how to keep what was done during the temporary state. Allow the long description to be hidden by setting advice.detachedHead configuration to false. We might want to customize the advice depending on how the commit to check out was spelled (e.g. instead of "new-branch-name", we way want to say "topic" when "git checkout origin/topic" triggered this message) in later updates, but this encapsulates that into a separate function and it should be a good first step.

Various commands refuse to run in the presence of conflicts (commit, merge, pull, cherry-pick/revert). They all used to provide rough, and inconsistant error messages. A new variable advice.resolveconflict is introduced, and allows more verbose messages, pointing the user to the appropriate solution. For commit, the error message used to look like this: $ git commit foo.txt: needs merge foo.txt: unmerged (c34a92682e0394bc0d6f4d4a67a8e2d32395c169) foo.txt: unmerged (3afcd75de8de0bb5076942fcb17446be50451030) foo.txt: unmerged (c9785d77b76dfe4fb038bf927ee518f6ae45ede4) error: Error building trees The "need merge" line is given by refresh_cache. We add the IN_PORCELAIN option to make the output more consistant with the other porcelain commands, and catch the error in return, to stop with a clean error message. The next lines were displayed by a call to cache_tree_update(), which is not reached anymore if we noticed the conflict. The new output looks like: U foo.txt fatal: 'commit' is not possible because you have unmerged files. Please, fix them up in the work tree, and then use 'git add/rm <file>' as appropriate to mark resolution and make a commit, or use 'git commit -a'. Pull is slightly modified to abort immediately if $GIT_DIR/MERGE_HEAD exists instead of waiting for merge to complain. The behavior of merge and the test-case are slightly modified to reflect the usual flow: start with conflicts, fix them, and afterwards get rid of MERGE_HEAD, with different error messages at each stage.
