2018-05-23Merge branch 'js/deprecate-grafts'Libravatar Junio C Hamano1-0/+2
The functionality of "$GIT_DIR/info/grafts" has been superseded by the "refs/replace/" mechanism for some time now, but the internal code had support for it in many places, which has been cleaned up in order to drop support of the "grafts" mechanism. * js/deprecate-grafts: Remove obsolete script to convert grafts to replace refs technical/shallow: describe why shallow cannot use replace refs technical/shallow: stop referring to grafts filter-branch: stop suggesting to use grafts Deprecate support for .git/info/grafts Add a test for `git replace --convert-graft-file` replace: introduce --convert-graft-file replace: prepare create_graft() for converting graft files wholesale replace: "libify" create_graft() and callees replace: avoid using die() to indicate a bug commit: Let the callback of for_each_mergetag return on error argv_array: offer to split a string by whitespace
2018-04-30Deprecate support for .git/info/graftsLibravatar Johannes 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.

2018-04-24push: colorize errorsLibravatar Ryan Dammrose1-2/+47
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. This patch colorizes the errors and hints (in red and yellow, respectively) so whenever there is a failure when pushing to a remote repository that fails, it is more noticeable.

2017-12-19Merge branch 'ls/editor-waiting-message'Libravatar Junio C Hamano1-0/+2
Git shows a message to tell the user that it is waiting for the user to finish editing when spawning an editor, in case the editor opens to a hidden window or somewhere obscure and the user gets lost. * ls/editor-waiting-message: launch_editor(): indicate that Git waits for user input refactor "dumb" terminal determination
2017-12-07launch_editor(): indicate that Git waits for user inputLibravatar Lars 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.

2017-06-15add: warn when adding an embedded repositoryLibravatar Jeff King1-0/+2
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.

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 conflictLibravatar Matthieu 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 booleanLibravatar Jeff 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 operationLibravatar Jeff 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_FORCELibravatar Junio 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 errorsLibravatar Christopher 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.

2011-12-22i18n of multi-line advice messagesLibravatar Junio C Hamano1-7/+16
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: ".

2010-01-29Reword "detached HEAD" notificationLibravatar Junio C Hamano1-0/+2
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.

2010-01-14commit: allow suppression of implicit identity adviceLibravatar Jeff King1-0/+2
We now nag the user with a giant warning when their identity was pulled from the username, hostname, and gecos information, in case it is not correct. Most users will suppress this by simply setting up their information correctly. However, there may be some users who consciously want to use that information, because having the value change from host to host contains useful information. These users can now set advice.implicitidentity to false to suppress the message. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-01-12Be more user-friendly when refusing to do something because of conflict.Libravatar Matthieu Moy1-0/+16
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.

2009-11-22merge-recursive: point the user to commit when file would be overwritten.Libravatar Matthieu Moy1-0/+2
The commit-before-pull is well accepted in the DVCS community, but is confusing some new users. This should get them back in the right way when the problem occurs. Signed-off-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-09-11status: make "how to stage" messages optionalLibravatar Jeff King1-0/+2
These messages are nice for new users, but experienced git users know how to manipulate the index, and these messages waste a lot of screen real estate. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-09-11push: make non-fast-forward help message configurableLibravatar Jeff King1-0/+25
This message is designed to help new users understand what has happened when refs fail to push. However, it does not help experienced users at all, and significantly clutters the output, frequently dwarfing the regular status table and making it harder to see. This patch introduces a general configuration mechanism for optional messages, with this push message as the first example.
