It is likely that those who came to Git after 3.0 switched the
default initial branch name to 'main' would still try to follow
tutorials that were written before 3.0 happened and with the
assumption that the tool would call the initial branch 'master'.
To help these new users after 3.0 boundary, let's retain one part of
the hint we will be giving before the default changes, namely, how
to rename the branch an unconfigured Git has created just once.
We do this without telling them how to permanently configure the
default name of the initial branch, and that design choice is very
much deliberate. The whole point of switching the default name was
because we did not want to force individual users to configure their
default branch name but while the hard wired default was 'master',
they _had_ to configure it away from 'master' in order to conform to
the recent norm, and a hint that tells them how to do so is useful.
But once the default is renamed to 'main', that no longer is true.
A narrower audience who are new users that follow an instruction
that assumes the initial branch name is 'master' would only need to
learn "here is how to change the branch name to match the tutorial
you are following in the repository you created for practice", and
"here is how you keep creating repositories with the first branch
with a name everybody hates" is unnecessary.
It also needs to be noted that the advise token to squelch the
message is the same advice.defaultBranchName as before, which is
also very much deliberate. The users who do have that configured
are those who _have_ been using Git since before 3.0, and they are
not the target audience for the new advice message. Reusing the
same advise token ensures that they do not have to turn the message
off.

Since 1296cbe4b46 (init: document `init.defaultBranch` better,
2020-12-11) "git-init.adoc" has advertised that the default name
of the initial branch may change in the future. The name "main"
is chosen to match the default used by the big Git forge web sites.
The advice printed when init.defaultBranch is not set is updated
to say that the default will change to "main" in Git 3.0. Building
with WITH_BREAKING_CHANGES enabled removes the advice and changes
the default branch name to "main". The code in guess_remote_head()
that looks for "refs/heads/master" is left unchanged as that is only
called when the remote server does not support the symref capability
in the v0 protocol or the symref extension to the ls-refs list in the
v2 protocol. Such an old server is more likely to be using "master"
as the default branch name.
With the exception of the "git-init.adoc" the documentation is left
unchanged. I had hoped to parameterize the name of the default branch
by using an asciidoc attribute. Unfortunately attribute expansion
is inhibited by backticks and we use backticks to mark up ref names
so that idea does not work. As the changes to git-init.adoc show
inserting ifdef's around each instance of the branch name "master"
is cumbersome and makes the documentation sources harder to read.
Apart from "git-init.adoc" there are some other files where "master" is
used as the name of the initial branch rather than as an example of a
branch name such as "user-manual.adoc" and "gitcore-tutorial.adoc". The
name appears a lot in those so updating it with ifdef's is not really
practical. We can update that document in the 3.0 release cycle. The
other documentation where master is used as an example branch name
can be gradually converted over time.

The default branch name advice message is displayed when
`repo_default_branch_name()` is invoked and the `init.defaultBranch`
config is not set. In this scenario, the advice message is always shown
even if the `--no-advice` option is used.
Adapt `repo_default_branch_name()` to allow the default branch name
advice message to be disabled with the `--no-advice` option and
corresponding configuration.

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
|
|
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.

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

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.

git-branch(1) will error out if you give it a bad ref name. But the user
might not understand why or what part of the name is illegal.
The user might know that there are some limitations based on the *loose
ref* format (filenames), but there are also further rules for
easier integration with shell-based tools, pathname expansion, and
playing well with reference name expressions.
The man page for git-check-ref-format(1) contains these rules. Let’s
advise about it since that is not a command that you just happen
upon. Also make this advise configurable since you might not want to be
reminded every time you make a little typo.

The user might not necessarily know why ff only was configured, maybe an

This can happen not only on pull.ff=only, but merge.ff=only too.
Even worse if the user has configured pull.rebase=false and
merge.ff=only, because in those cases a diverging merge will constantly
keep failing. There's no trivial way to get out of this other than
`git merge --no-ff`.

For sanity, we should probably do one of the following:
(a) make C and header files both depend upon everything they need
(b) consistently exclude git-compat-util.h from headers and require it
be the first include in C files
Currently, we have some of the headers following (a) and others
following (b), which makes things messy. In the past I was pushed
towards (b), as per [1] and [2]. Further, during this series I
discovered that this mixture empirically will mean that we end up with C
files that do not directly include git-compat-util.h, and do include
headers that don't include git-compat-util.h, with the result that we
likely have headers included before an indirect inclusion of
git-compat-util.h. Since git-compat-util.h has tricky platform-specific
stuff that is meant to be included before everything else, this state of
affairs is risky and may lead to things breaking in subtle ways (and
only on some platforms) as per [1] and [2].
Since including git-compat-util.h in existing header files makes it
harder for us to catch C files that are missing that include, let's
switch to (b) to make the enforcement of this rule easier. Remove the
inclusion of git-compat-util.h from header files other than the ones
that have been approved as alternate first includes.

The error "not tracking: ambiguous information for ref" is raised

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'.

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).

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.

- Checking if the <src> being pushed ('v2.19.0^{commit}')
is a ref in "refs/{heads,tags}/". If so we add a corresponding
refs/{heads,tags}/ prefix on the remote side.
Neither worked, so we gave up. You must fully qualify the ref.

"git checkout" and "git worktree add" learned to honor
checkout.defaultRemote when auto-vivifying a local branch out of a
remote tracking branch in a repository with multiple remotes that
have tracking branches that share the same names.
* ab/checkout-default-remote:
checkout & worktree: introduce checkout.defaultRemote
checkout: add advice for ambiguous "checkout <branch>"
builtin/checkout.c: use "ret" variable for return
checkout: pass the "num_matches" up to callers
checkout.c: change "unique" member to "num_matches"
checkout.c: introduce an *_INIT macro
checkout.h: wrap the arguments to unique_tracking_name()
checkout tests: index should be clean after dwim checkout
|
|
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.

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.

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
|
|
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.

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.

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.

introducing a new function called error_resolve_conflict.
Re-implement die_resolve_conflict as a call to error_resolve_conflict
followed by a call to die. Consequently, the message printed by
die_resolve_conflict changes from
fatal: 'commit' is not possible because you have unmerged files.
Please, fix them up in the work tree ...
...
to
error: 'commit' is not possible because you have unmerged files.
hint: Fix them up in the work tree ...
hint: ...
fatal: Exiting because of an unresolved conflict.
Hints are printed using the same advise function introduced in
v1.7.3-rc0~26^2~3 (Introduce advise() to print hints, 2010-08-11).

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.

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.

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.

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.

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.

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.
