This was discussed in the Discord a while ago, and this is the logical and consistent
conclusion. Implementing it as such makes it consistent with both `jj edit` and `jj new`
which make hidden commits such as predecessors visible.
This actually was Martins work, I just added the tests.

Since we need to scan directory entries recursively in order to detect new
untracked paths, it doesn't make sense to reuse the .gitignore code path.
This change means all untracked file paths are listed in "jj status" even if
the whole directory is untracked. It might be a bit verbose, but should be
okay. Directories like node_modules should be excluded by .gitignore, not by
auto-track pattern.
Fixes#5389
With git.subprocess = true, it's more important to skip unneeded remote
operations. Each remote command may involve user intervention if authentication
requires manual step.
This change also means that the remote connection is no longer reused in git2
impl. I think the added cost is acceptable. The git2 impl will hopefully be
removed soon, and the remote branch name is needed only when cloning new repo.
The current comment uses `[noeol]`, which can be difficult to
understand. In this commit, the brackets are changed to parentheses to
make it clear that there is no semantic meaning to the comment, and the
wording is changed to be more clear to the user.
Git doesn't show this information in their "diff3" style either, and it
looks a bit strange having two different bracketed sections of text next
to each other, so I think it would be better to remove it.
* Make the new `GitFetch` api public.
* Move `git::fetch` to `lib/tests/test_git.rs` as `git_fetch`, to minimize
churn in the tests. Update test call sites to use `git_fetch`
* Delete the `git::fetch` from `lib/src/git.rs`.
* Update `jj git clone` and `git_fetch` in `cli/src/git_utils.rs` to use
the new api directly. Removing one redundant layer of indirection.
* This fixes#4920 as it first fetches from all remotes before `import_refs()`
is called, so there is no race condition if the same commit is treated
differently in different remotes specified in the same command.

A missing newline would cause the following conflict markers to become
invalid when materializing the conflict, so we add a newline to prevent
this from happening. When parsing, if we parsed a conflict at the end of
the file which ended in a newline, we can check whether the file
actually did end in a newline, and then remove the newline if it didn't.
File conflicts have been simplified during materialization since 0.19.0,
so it should be safe to remove support for unsimplified conflicts now.
This will make implementing the next commit easier, since it won't have
to support unsimplified conflicts.
Currently, the Git subprocess tests only work on Linux due to a default
path being used for the `git` executable when `$PATH` is unset. This can
break if Git isn't installed at the expected path. Also, I believe it is
currently necessary to set the `$TEST_GIT_EXECUTABLE_PATH` environment
variable on Windows for tests to pass. Instead, we should use the user's
`$PATH` to locate the `git` executable, as well as any other executables
that are needed. This also makes `$TEST_GIT_EXECUTABLE_PATH` no longer
necessary, so it can be removed.
In some cases, there are non trivial codepaths for fetching multiple
branches explicitly. In particular, it might be the case that fetching
works for n = 2 but not n = 3.
This commit changes a cli test to have 3 remotes and 3 branches, and a
lib test with 3 branches, only one of them succeds.
I'll make "jj abandon" delete bookmarks by default. This could be handled by
cmd_abandon(), but we'll need a repo API if we also want to change the behavior
of "jj rebase --skip-emptied".
Instead of setting the index to match the tree of HEAD, we now set the
index to the merged parent tree of the working copy commit. This means
that if you edit a merge commit, it will make the Git index look like it
would in the middle of a `git merge` operation (with all of the
successfully-merged files staged in the index).
If there are any 2-sided conflicts in the merged parent tree, then they
will be added to the index as conflicts. Since Git doesn't support
conflicts with more than 2 sides, many-sided conflicts are staged as the
first side of the conflict. The following commit will improve this.
This will give us more fine-grained control over what files we put in
the index, allowing us to create conflicted index states. We also still
need to use git2 to clean up the merge/rebase state, since gix doesn't
have any function for this currently.
These tests should still pass after we switch to gix for resetting the
index, so we need to make sure they don't rely on the cached index from
the `git2::Repository` instance.
We need to make `TestSigningBackend` available for cli tests, as we will
add cli tests for signing related functionality (templates for
displaying commit signatures, `jj sign`) in upcoming commits.

I'm going to remove the settings argument from start_transaction(),
new_commit(), and rewrite_commit(), and these functions will use the settings
passed in to the constructor.
It's nice that "jj config list --include-defaults" can show these default
values.
I just copied the jj-cli directory structure, but it's unlikely we'll add more
config/*.toml files.
These paths may be printed, compared with user inputs, or passed to external
programs. It's probably better to avoid unusual "\\?\C:\" paths on Windows.
Fixes#5143
Storing the conflict marker length in the working copy makes conflict
parsing more consistent, and it allows us to parse valid conflict hunks
even if the user left some invalid conflict markers in the file while
resolving the conflicts.
If a file contains lines which look like conflict markers, then we need
to make the real conflict markers longer so that the materialized
conflicts can be parsed unambiguously.
When parsing the conflict, we require that the conflict markers are at
least as long as the materialized conflict markers based on the current
tree. This can lead to some unintuitive edge cases which will be solved
in the next commit.
For instance, if we have a file explaining the differences between
Jujutsu's conflict markers and Git's conflict markers, it could produce
a conflict with long markers like this:
```
<<<<<<<<<<< Conflict 1 of 1
%%%%%%%%%%% Changes from base to side #1
Jujutsu uses different conflict markers than Git, which just shows the
-sides of a conflict without a diff.
+sides of a conflict without a diff:
+
+<<<<<<<
+left
+|||||||
+base
+=======
+right
+>>>>>>>
+++++++++++ Contents of side #2
Jujutsu uses different conflict markers than Git:
<<<<<<<
%%%%%%%
-base
+left
+++++++
right
>>>>>>>
>>>>>>>>>>> Conflict 1 of 1 ends
```
We should support these options for "git" conflict marker style as well,
since Git actually does support producing longer conflict markers in
some cases through .gitattributes:
https://git-scm.com/docs/gitattributes#_conflict_marker_size
We may also want to support passing the conflict marker length to merge
tools as well in the future, since Git supports a "%L" parameter to pass
the conflict marker length to merge drivers:
https://git-scm.com/docs/gitattributes#_defining_a_custom_merge_driver
We can usually omit quotes in --config=NAME=VALUE, but an RFC3339 string is a
valid TOML date-time expression. It's weird that quoting is required to specify
a date-time value.
I think this provides a better UX than refusing any operation due to large
files. Because untracked files won't be overwritten, it's usually safe to
continue operation ignoring the untracked files. One caveat is that new large
files can become tracked if files of the same name checked out. (see the test
case)
FWIW, the warning will be printed only once if watchman is enabled. If we use
the snapshot stats to print untracked paths in "jj status", this will be a
problem.
Closes#3616, #3912
