rebase: improve detection of rebase in progress

Detect early on if a rebase is in progress and what type of rebase it
is (interactive, merge-based or am-based). This prepares for further
refactoring where am-based rebase will be dispatched to
git-rebase--am.sh and merge-based rebase will be dispatched to
git-rebase--merge.sh.

The idea is to use the same variables whether the type of rebase was
detected from rebase-apply/ or rebase-merge/ directories or from the
command line options. This will make the code more readable and will
later also make it easier to dispatch to the type-specific scripts.

Also show a consistent error message independent of the type of rebase
that was in progress and remove the obsolete wording about being in
the middle of a 'patch application', since that (an existing

13 years agorebase: refactor reading of state
Martin von Zweigbergk [Sun, 6 Feb 2011 18:43:31 +0000 (13:43 -0500)]
rebase: refactor reading of state

The code reading the state saved in $merge_dir or $rebase_dir is
currently spread out in many places, making it harder to read and to
introduce additional state. Extract this code into one method that
reads the state. Only extract the code associated with the state that
is written when the rebase is initiated. Leave the state that changes
for each commmit, at least for now.

Currently, when resuming a merge-based rebase using --continue or
--skip, move_to_original_branch (via finish_rb_merge) will be called
without head_name and orig_head set. These variables are then lazily
read in move_to_original_branch if head_name is not set (together with
onto, which is unnecessarily read again). Change this by always
eagerly reading the state, for both am-based and merge-based rebase,
in the --continue and --skip cases. Note that this does not change the
behavior for am-based rebase, which read the state eagerly even before
this commit.

Reading the state eagerly means that part of the state will sometimes
be read unnecessarily. One example is when the rebase is continued,
but stops again at another merge conflict. Another example is when the
rebase is aborted. However, since both of these cases involve user
interaction, the delay is hopefully not noticeable. The
call_merge/continue_merge loop is not affected.

fast-import: introduce "feature notes" command

Here is a 'feature' command for streams to use to require support for
the notemodify (N) command.

When the 'feature' facility was introduced (v1.7.0-rc0~95^2~4,
2009-12-04), the notes import feature was old news (v1.6.6-rc0~21^2~8,
2009-10-09) and it was not obvious it deserved to be a named feature.
But now that is clear, since all major non-git fast-import backends
lack support for it.

Details: on git version with this patch applied, any "feature notes"
command in the features/options section at the beginning of a stream
will be treated as a no-op.  On fast-import implementations without
the feature (and older git versions), the command instead errors out
with a message like

This version of fast-import does not support feature notes.

So by declaring use of notes at the beginning of a stream, frontends
can avoid wasting time and other resources when the backend does not
support notes.  (This would be especially important for backends that
do not support rewinding history after a botched import.)

rebase -i: clarify in-editor documentation of "exec"

The hints in the current "instruction sheet" template look like so:

 # Rebase 3f14246..a1d7e01 onto 3f14246
 #
 # Commands:
 #  p, pick = use commit
 #  r, reword = use commit, but edit the commit message
 #  e, edit = use commit, but stop for amending
 #  s, squash = use commit, but meld into previous commit
 #  f, fixup = like "squash", but discard this commit's log message
 #  x <cmd>, exec <cmd> = Run a shell command <cmd>, and stop if it fails
 #
 # If you remove a line here THAT COMMIT WILL BE LOST.
 # However, if you remove everything, the rebase will be aborted.
 #

This does not make it clear that the format of each line is

<insn> <commit id> <explanatory text that will be printed>

but the reader will probably infer that from the automatically
generated pick examples above it.

What about the "exec" instruction?  By analogy, I might imagine that
the format of that line is "exec <command> <explanatory text>", and
the "x <cmd>" hint does not address that question (at first I read it
as taking an argument <cmd> that is the name of a shell).  Meanwhile,
the mention of <cmd> makes the hints harder to scan as a table.

So remove the <cmd> and add some words to remind the reader that
"exec" runs a command named by the rest of the line.  To make room, it
is left to the manpage to explain that that command is run using
$SHELL and that nonzero status from that command will pause the
rebase.

M 040000 4b825dc642cb6eb9a060e54bf8d69288fbee4904 subdir

One can trigger this by reading an empty tree (for example, the tree
corresponding to an empty root commit) and trying to move it to a
subtree.  It is better and more closely analogous to 'git read-tree

rebase: use explicit "--" with checkout

In the case of a ref/pathname conflict, checkout will
already do the right thing and checkout the ref. However,
for a non-existant ref, this has two advantages:

  1. If a file with that pathname exists, rebase will
     refresh the file from the index and then rebase the
     current branch instead of producing an error.

  2. If no such file exists, the error message using an
     explicit "--" is better:

       # before
       $ git rebase -i origin bogus

       # after
       $ git rebase -i origin bogus
       fatal: invalid reference: bogus

The problems seem to be trigger-able only through "git
rebase -i", as regular git-rebase checks the validity of the

Subject: setup: officially support --work-tree without --git-dir

The original intention of --work-tree was to allow people to work in a
subdirectory of their working tree that does not have an embedded .git
directory.  Because their working tree, which their $cwd was in, did not
have an embedded .git, they needed to use $GIT_DIR to specify where it is,
and because this meant there was no way to discover where the root level
of the working tree was, so we needed to add $GIT_WORK_TREE to tell git
where it was.

However, this facility has long been (mis)used by people's scripts to
start git from a working tree _with_ an embedded .git directory, let git
find .git directory, and then pretend as if an unrelated directory were
the associated working tree of the .git directory found by the discovery
process.  It happens to work in simple cases, and is not worth causing
"regression" to these scripts.

Rearrange code to be easier to browse:

 - first data
 - then functions
 - then test assertions

Mark up inline test vectors as

  cat >vector <<-\EOF

for visual scannability.  Use words like "set up" for tests that set
up for other tests, to make it obvious which tests are safe to skip.
Use repeated function calls instead of a loop for the
language-specific tests, so the invocations can be easily tweaked
individually (for example if one starts to fail).

This means if you add a new subdirectory to t4034/, it will not be
automatically used.  I think that's worth it for the added
explicitness.

userdiff: simplify word-diff safeguard

git's diff-words support has a detail that can be a little dangerous:
any text not matched by a given language's tokenization pattern is
treated as whitespace and changes in such text would go unnoticed.
Therefore each of the built-in regexes allows a special token type
consisting of a single non-whitespace character [^[:space:]].

To make sure UTF-8 sequences remain human readable, the builtin
regexes also have a special token type for runs of bytes with the high
bit set.  In English, non-ASCII characters are usually isolated so
this is analogous to the [^[:space:]] pattern, except it matches a
single _multibyte_ character despite use of the C locale.

Unfortunately it is easy to make typos or forget entirely to include
these catch-all token types when adding support for new languages (see
v1.7.3.5~16, userdiff: fix typo in ruby and python word regexes,
2010-12-18).  Avoid this by including them automatically within the
PATTERNS and IPATTERN macros.

While at it, change the UTF-8 sequence token type to match exactly one
non-ASCII multi-byte character, rather than an arbitrary run of them.

t4034: bulk verify builtin word regex sanity

The builtin word regexes should be tested with some simple examples
against simple issues.  Do this in bulk.

Mainly due to a lack of language knowledge and inspiration, most of
the test cases (cpp, csharp, java, objc, pascal, php, python, ruby)
are directly based off a C operator precedence table to verify that
all operators are split correctly.  This means that they are probably
incomplete or inaccurate except for 'cpp' itself.

Still, they are good enough to already have uncovered a typo in the
python and ruby patterns.

'fortran' is based on my anecdotal knowledge of the DO10I parsing
rules, and thus probably useless.  The rest (bibtex, html, tex) are an
ad-hoc test of what I consider important splits in those languages.

fast-import: Introduce --import-marks-if-exists

When a frontend uses a marks file to ensure its state persists between
runs, it may represent "clean slate" when bootstrapping with "no marks
yet". In such a case, feeding the last state with --import-marks and
saving the state after the current run with --export-marks would be a
natural thing to do.

The --import-marks option however errors out when the specified marks file
doesn't exist; this makes bootstrapping a bit difficult.  The location of
the marks file becomes backend-dependent when --relative-marks is in
effect, and the frontend cannot check for the existence of the file in
such a case.

The --import-marks-if-exists option does the same thing as --import-marks
but does not flag an error if the named file does not exist yet to help
these frontends.

unpack-trees: handle lstat failure for existing file

README -> Readme) that is significant to git but insignificant to the
underlying filesystem.  If lstat fails, these checks are performed
with an uninitialied stat structure, producing essentially random
results.

Better to just error out when lstat fails.
