Branch names are usually in ASCII so they are not the problem. The
problem most likely comes from "(no branch)" translation, which is
in UTF-8 and makes display-width calculation just wrong. Clarify
this by renaming the field "len" in struct ref_item to "width", as
it stores the display-width and is used to compute the width of the
screen needed to show the names of all the branches, and compute the
display width using utf8_strwidth(), not byte-length with strlen().
Update document to mention the fact that we may want ref names in
UTF-8. Encodings that produce invalid UTF-8 are safe as utf8_strwidth()
falls back to strlen(). The ones that incidentally produce valid UTF-8
sequences will cause misalignment.

Either end of revision range operator can be omitted to default to HEAD,
as in "origin.." (what did I do since I forked) or "..origin" (what did
they do since I forked). But the current parser interprets ".." as an
empty range "HEAD..HEAD", and worse yet, because ".." does exist on the

The existing --set-uptream option can cause confusion, as it uses the
usual branch convention of assuming a starting point of HEAD if none
is specified, causing
git branch --set-upstream origin/master
to create a new local branch 'origin/master' that tracks the current
branch. As --set-upstream already exists, we can't simply change its
behaviour. To work around this, introduce --set-upstream-to which
accepts a compulsory argument indicating what the new upstream branch
should be and one optinal argument indicating which branch to change,
defaulting to HEAD.
The new options allows us to type
git branch --set-upstream-to origin/master

When asciidoc converts a listing block like:
----------------------
$ git log --merge
----------------------
it marks it to be displayed in a monospace font. This works
fine when generating HTML output. However, when generating
docbook output, we override the expansion of a listingblock
to work around bugs in some versions of the docbook
toolchain. Our override did not mark the listingblock with
the "monospaced" class.
The main output that uses docbook as an intermediate format
is the manpages. We didn't notice any issue there because
the monospaced class seems to be ignored when generating
roff from the docbook manpages.
However, when generating texinfo to make info pages, docbook
does respect this class. The resulting texinfo output
properly uses "@example" blocks to display the listing in
this case. Besides possibly looking prettier in some texinfo
backends, one important effect is that the monospace font
suppresses texinfo's expansion of "--" and "---" into
en-dashes and em-dashes. With the current code, the example
above ends up looking like "git log -merge", which is
confusing and wrong.

Mac OS X mangles file names containing unicode on file systems HFS+,
VFAT or SAMBA. When a file using unicode code points outside ASCII
is created on a HFS+ drive, the file name is converted into
decomposed unicode and written to disk. No conversion is done if
the file name is already decomposed unicode.
Calling open("\xc3\x84", ...) with a precomposed "Ä" yields the same
result as open("\x41\xcc\x88",...) with a decomposed "Ä".
As a consequence, readdir() returns the file names in decomposed
unicode, even if the user expects precomposed unicode. Unlike on
HFS+, Mac OS X stores files on a VFAT drive (e.g. an USB drive) in
precomposed unicode, but readdir() still returns file names in
decomposed unicode. When a git repository is stored on a network
share using SAMBA, file names are send over the wire and written to
disk on the remote system in precomposed unicode, but Mac OS X
readdir() returns decomposed unicode to be compatible with its
behaviour on HFS+ and VFAT.
The unicode decomposition causes many problems:
- The names "git add" and other commands get from the end user may
often be precomposed form (the decomposed form is not easily input
from the keyboard), but when the commands read from the filesystem
to see what it is going to update the index with already is on the
filesystem, readdir() will give decomposed form, which is different.
- Similarly "git log", "git mv" and all other commands that need to
compare pathnames found on the command line (often but not always
precomposed form; a command line input resulting from globbing may
be in decomposed) with pathnames found in the tree objects (should
be precomposed form to be compatible with other systems and for
consistency in general).
- The same for names stored in the index, which should be
precomposed, that may need to be compared with the names read from
readdir().
NFS mounted from Linux is fully transparent and does not suffer from
the above.
As Mac OS X treats precomposed and decomposed file names as equal,
we can
- wrap readdir() on Mac OS X to return the precomposed form, and
- normalize decomposed form given from the command line also to the
precomposed form,
to ensure that all pathnames used in Git are always in the
precomposed form. This behaviour can be requested by setting
"core.precomposedunicode" configuration variable to true.
The code in compat/precomposed_utf8.c implements basically 4 new
functions: precomposed_utf8_opendir(), precomposed_utf8_readdir(),
precomposed_utf8_closedir() and precompose_argv(). The first three
are to wrap opendir(3), readdir(3), and closedir(3) functions.
The argv[] conversion allows to use the TAB filename completion done
by the shell on command line. It tolerates other tools which use
readdir() to feed decomposed file names into git.
When creating a new git repository with "git init" or "git clone",
"core.precomposedunicode" will be set "false".
The user needs to activate this feature manually. She typically
sets core.precomposedunicode to "true" on HFS and VFAT, or file
systems mounted via SAMBA.

- $HOME/.gitconfig file doesn't, and
- The --global option is used.
Otherwise, write to $HOME/.gitconfig when the --global option is

To use the feature of core.excludesfile, the user needs:
1. to create such a file,
2. and add configuration variable to point at it.
Instead, we can make this a one-step process by choosing a default value
which points to a filename in the user's $HOME, that is unlikely to
already exist on the system, and only use the presence of the file as a
cue that the user wants to use that feature.
And we use "${XDG_CONFIG_HOME:-$HOME/.config/git}/ignore" as such a
file, in the same directory as the newly added configuration file
("${XDG_CONFIG_HOME:-$HOME/.config/git}/config). The use of this
directory is in line with XDG specification as a location to store
such application specific files.

Commit fe77b41 introduced a new attribute to let the linkgit macro

and otherwise leave it unset under the assumption that it would default

When given a set of commits, cherry-pick will apply the changes for
all of them. Specifying a simple range will also work as expected.
This can lead the user to think that

Instead the revs are given to a single invocation of rev-list, which

During an interactive rebase session, it is sometimes desirable to
run tests on each commit in the resulting history. This can be done
by adding "exec <test command>" when editing the insn sheet, but the
command used for testing is often the same for all resulting commits.
By passing "--exec <cmd>" from the command line, automatically add
these "exec" lines after each commit in the final history. To work
well with the --autosquash option, these are added at the end of
each run of "fixup" and "squash".

Most of our documentation is in a single directory, so using
linkgit:git-config[1] just generates a relative link in the
same directory. However, this is not the case with the API
documentation in technical/*, which need to refer to
git-config from the parent directory.
We can fix this by passing a special prefix attribute when building
in a subdirectory, and respecting that prefix in our linkgit
definitions.
We only have to modify the html linkgit definition. For
manpages, we can ignore this for two reasons:
1. we do not generate actual links to the file in
manpages, but instead just give the name and section of
the linked manpage
2. we do not currently build manpages for subdirectories,

This comment warns about a bug in asciidoc 6, and points to

When we made the switch to supporting asciidoc 8 in 4c7100a
(Documentation: adjust to AsciiDoc 8, 2007-06-14), we were
able to leave most of the documentation intact by defining
asciidoc7compatible.
Since commit 6cf378f (docs: stop using asciidoc no-inline-literal,
2012-04-26), we don't support versions of asciidoc older
than 8.4.1, which is when inline literals were introduced.
Therefore there is not much point in keeping our
documentation compatible with asciidoc 7.
So we are now free to drop the asciidoc7compatible flag and
update the documentation itself to assume asciidoc8.
Fortunately, doing the latter is very easy; we weren't using
any of the constructs impacted by asciidoc7compatible, so
there are no changes to make.
The reason is somewhat subtle. The asciidoc7compatible
affects only super/sub-scripts ("^" and "~") and index
terms. We don't use the latter at all. Nor we do we use the
former, but we did have to protect them from accidental
expansion in constructs like "rev^1". However, all of our
uses of "~" and "^" are either in code blocks (which are
rendered literally), or inside backticks. Prior to 6cf378f,
backticks were not inline literals, and needed proper
quoting. But post-6cf378f, we don't have to worry whether we
are using the old or new rules, as those characters are not
interpreted at all in either case.
I verified that the result of "make install-html
install-man" is identical before and after this patch on
asciidoc 8.6.7.

"git grep -e '$pattern'", unlike the case where the patterns are read from

From the FILES section of the git-config(1) manual:
$GIT_DIR/config::
Repository specific configuration file. (The filename is
of course relative to the repository root, not the working
directory.)
That's confusing because $GIT_DIR really is relative to the working
directory.
$ GIT_DIR=.git GIT_EDITOR='pwd; echo editing'
$ export GIT_DIR GIT_EDITOR
$ git config --edit --local
/home/jrn/src/git/Documentation

It turns out that the comment is a remnant from older days when the
heading said ".git/config" (which is indeed relative to the top of the
worktree).
It was only when the heading was changed to refer more precisely to

When getpwuid fails, we give a cute but cryptic message.
While it makes sense if you know that getpwuid or identity
functions are being called, this code is triggered behind
the scenes by quite a few git commands these days (e.g.,
receive-pack on a remote server might use it for a reflog;
the current message is hard to distinguish from an
authentication error). Let's switch to something that gives
a little more context.
While we're at it, we can factor out all of the
cut-and-pastes of the "you don't exist" message into a
wrapper function. Rather than provide xgetpwuid, let's make
it even more specific to just getting the passwd entry for
the current uid. That's the only way we use getpwuid anyway,
and it lets us make an even more specific error message.
The current message also fails to mention errno. While the
usual cause for getpwuid failing is that the user does not
exist, mentioning errno makes it easier to diagnose these
problems. Note that POSIX specifies that errno remain
untouched if the passwd entry does not exist (but will be
set on actual errors), whereas some systems will return
ENOENT or similar for a missing entry. We handle both cases
in our wrapper.

When we pull the user's name from the GECOS field of the
passwd file (or generate an email address based on their
username and hostname), we put the result into a
static buffer. While it's extremely unlikely that anybody
ever hit these limits (after all, in such a case their
parents must have hated them), we still had to deal with the
error cases in our code.
Converting these static buffers to strbufs lets us simplify
the code and drop some error messages from the documentation
that have confused some users.
The conversion is mostly mechanical: replace string copies
with strbuf equivalents, and access the strbuf.buf directly.
There are a few exceptions:
- copy_gecos and copy_email are the big winners in code
reduction (since they no longer have to manage the
string length manually)
- git_ident_config wants to replace old versions of
the default name (e.g., if we read the config multiple
times), so it must reset+add to the strbuf instead of
just adding
Note that there is still one length limitation: the
gethostname interface requires us to provide a static
buffer, so we arbitrarily choose 1024 bytes for the
hostname.

Number of columns required for change counts is now computed based on
the maximum number of changed lines instead of being fixed. This means
that usually a few more columns will be available for the filenames
and the graph.
The graph width logic is also modified to include enough space for
"Bin XXX -> YYY bytes".
If changes to binary files are mixed with changes to text files,
change counts are padded to take at least three columns. And the other
way around, if change counts require more than three columns, then
"Bin"s are padded to align with the change count. This way, the +-
part starts in the same column as "XXX -> YYY" part for binary files.
This makes the graph easier to parse visually thanks to the empty
column. This mimics the layout of diff --stat before this change.
Tests and the tutorial are updated to reflect the new --stat output.
This means either the removal of extra padding and/or the addition of
up to three extra characters to truncated filenames. One test is added
to check the graph alignment when a binary file change and text file
change of more than 999 lines are committed together.

Normally all cells (and in turn columns) share the same width. This
layout mode can waste space because one long item can stretch our all
columns.
With COL_DENSE enabled, column width is calculated indepdendently. All
columns are shrunk to minimum, then it attempts to push cells of the
last row over to the next column with hope that everything still fits
even there's one row less. The process is repeated until the new layout
cannot fit in given width any more, or there's only one row left
(perfect!).
Apparently, this mode consumes more cpu than the old one, but it makes
better use of terminal space. For layouting one or two screens, cpu
usage should not be detectable.
This patch introduces option handling code besides layout modes and
enable/disable to expose this feature as "dense". The feature can be
turned off by specifying "nodense".

In asciidoc 7, backticks like `foo` produced a typographic
effect, but did not otherwise affect the syntax. In asciidoc
8, backticks introduce an "inline literal" inside which markup
is not interpreted. To keep compatibility with existing
documents, asciidoc 8 has a "no-inline-literal" attribute to
keep the old behavior. We enabled this so that the
documentation could be built on either version.
It has been several years now, and asciidoc 7 is no longer
in wide use. We can now decide whether or not we want
inline literals on their own merits, which are:
1. The source is much easier to read when the literal
contains punctuation. You can use `master~1` instead
of `master{tilde}1`.
2. They are less error-prone. Because of point (1), we
tend to make mistakes and forget the extra layer of
quoting.
This patch removes the no-inline-literal attribute from the
Makefile and converts every use of backticks in the
documentation to an inline literal (they must be cleaned up,
or the example above would literally show "{tilde}" in the
output).
Problematic sites were found by grepping for '`.*[{\\]' and
examined and fixed manually. The results were then verified
by comparing the output of "html2text" on the set of
generated html pages. Doing so revealed that in addition to
making the source more readable, this patch fixes several
formatting bugs:
- HTML rendering used the ellipsis character instead of
literal "..." in code examples (like "git log A...B")
- some code examples used the right-arrow character
instead of '->' because they failed to quote
- api-config.txt did not quote tilde, and the resulting
HTML contained a bogus snippet like:
<tt><sub></tt> foo <tt></sub>bar</tt>
which caused some parsers to choke and omit whole
sections of the page.
- git-commit.txt confused ``foo`` (backticks inside a
literal) with ``foo'' (matched double-quotes)
- mentions of `A U Thor <author@example.com>` used to
erroneously auto-generate a mailto footnote for
author@example.com
- the description of --word-diff=plain incorrectly showed
the output as "[-removed-] and {added}", not "{+added+}".
- using "prime" notation like:
commit `C` and its replacement `C'`
confused asciidoc into thinking that everything between
the first backtick and the final apostrophe were meant
to be inside matched quotes
- asciidoc got confused by the escaping of some of our
asterisks. In particular,
`credential.\*` and `credential.<url>.\*`
properly escaped the asterisk in the first case, but
literally passed through the backslash in the second
case.

When calling "git push" without argument, we want to allow Git to do
something simple to explain and safe. push.default=matching is unsafe
when used to push to shared repositories, and hard to explain to
beginners in some contexts. It is debatable whether 'upstream' or
'current' is the safest or the easiest to explain, so introduce a new
mode called 'simple' that is the intersection of them: push to the
upstream branch, but only if it has the same name remotely. If not, give
an error that suggests the right command to push explicitely to
'upstream' or 'current'.
A question is whether to allow pushing when no upstream is configured. An
argument in favor of allowing the push is that it makes the new mode work
in more cases. On the other hand, refusing to push when no upstream is
configured encourages the user to set the upstream, which will be
beneficial on the next pull. Lacking better argument, we chose to deny
the push, because it will be easier to change in the future if someone
shows us wrong.

The git-cherry-pick --allow-empty command by default only preserves empty
commits that were originally empty, i.e only those commits for which
<commit>^{tree} and <commit>^^{tree} are equal. By default commits which are
non-empty, but were made empty by the inclusion of a prior commit on the current
history are filtered out. This option allows us to override that behavior and
include redundant commits as empty commits in the change history.
Note that this patch changes the default behavior of git cherry-pick slightly.
Prior to this patch all commits in a cherry-pick sequence were applied and git
commit was run. The implication here was that, if a commit was redundant, and
the commit did not trigger the fast forward logic, the git commit operation, and
therefore the git cherry-pick operation would fail, displaying the cherry pick
advice (i.e. run git commit --allow-empty). With this patch however, such
redundant commits are automatically skipped without stopping, unless
--keep-redundant-commits is specified, in which case, they are automatically
applied as empty commits.

The existing label import code looks at each commit being
imported, and then checks for labels at that commit. This
doesn't work in the real world though because it will drop
labels applied on changelists that have already been imported,
a common pattern.
This change adds a new --import-labels option. With this option,
at the end of the sync, git p4 gets sets of labels in p4 and git,
and then creates a git tag for each missing p4 label.
This means that tags created on older changelists are
still imported.
Tags that could not be imported are added to an ignore
list.
The same sets of git and p4 tags and labels can also be used to
derive a list of git tags to export to p4. This is enabled with

If a remote repo has too many tags (or branches), cloning it over the
smart HTTP transport can fail because remote-curl.c puts all the refs
from the remote repo on the fetch-pack command line. This can make the
command line longer than the global OS command line limit, causing
fetch-pack to fail.
This is especially a problem on Windows where the command line limit is
orders of magnitude shorter than Linux. There are already real repos out
there that msysGit cannot clone over smart HTTP due to this problem.
Here is an easy way to trigger this problem:
git init too-many-refs
cd too-many-refs
echo bla > bla.txt
git add .
git commit -m test
sha=$(git rev-parse HEAD)
tag=$(perl -e 'print "bla" x 30')
for i in `seq 50000`; do
echo $sha refs/tags/$tag-$i >> .git/packed-refs
done
Then share this repo over the smart HTTP protocol and try cloning it:
$ git clone http://localhost/.../too-many-refs/.git
Cloning into 'too-many-refs'...
fatal: cannot exec 'fetch-pack': Argument list too long
50k tags is obviously an absurd number, but it is required to
demonstrate the problem on Linux because it has a much more generous
command line limit. On Windows the clone fails with as little as 500
tags in the above loop, which is getting uncomfortably close to the
number of tags you might see in real long lived repos.
This is not just theoretical, msysGit is already failing to clone our
company repo due to this. It's a large repo converted from CVS, nearly
10 years of history.
Four possible solutions were discussed on the Git mailing list (in no
particular order):
1) Call fetch-pack multiple times with smaller batches of refs.
This was dismissed as inefficient and inelegant.
2) Add option --refs-fd=$n to pass a an fd from where to read the refs.
This was rejected because inheriting descriptors other than
stdin/stdout/stderr through exec() is apparently problematic on Windows,
plus it would require changes to the run-command API to open extra
pipes.
3) Add option --refs-from=$tmpfile to pass the refs using a temp file.
This was not favored because of the temp file requirement.
4) Add option --stdin to pass the refs on stdin, one per line.
In the end this option was chosen as the most efficient and most
desirable from scripting perspective.
There was however a small complication when using stdin to pass refs to
fetch-pack. The --stateless-rpc option to fetch-pack also uses stdin for
communication with the remote server.
If we are going to sneak refs on stdin line by line, it would have to be
done very carefully in the presence of --stateless-rpc, because when
reading refs line by line we might read ahead too much data into our
buffer and eat some of the remote protocol data which is also coming on
stdin.
One way to solve this would be to refactor get_remote_heads() in
fetch-pack.c to accept a residual buffer from our stdin line parsing
above, but this function is used in several places so other callers
would be burdened by this residual buffer interface even when most of
them don't need it.
In the end we settled on the following solution:
If --stdin is specified without --stateless-rpc, fetch-pack would read
the refs from stdin one per line, in a script friendly format.
However if --stdin is specified together with --stateless-rpc,
fetch-pack would read the refs from stdin in packetized format
(pkt-line) with a flush packet terminating the list of refs. This way we
can read the exact number of bytes that we need from stdin, and then
get_remote_heads() can continue reading from the same fd without losing
a single byte of remote protocol data.
This way the --stdin option only loses generality and scriptability when
used together with --stateless-rpc, which is not easily scriptable
anyway because it also uses pkt-line when talking to the remote server.

Some distributors customize the fallback pager and editor used by git
commands when the user has not indicated a preference via the
core.editor/core.pager configuration or GIT_EDITOR, GIT_PAGER, VISUAL,
EDITOR, and PAGER environment variables, and git's build system
provides DEFAULT_PAGER and DEFAULT_EDITOR makefile settings to help
them with that (see v1.6.6-rc0~24, 2009-11-20).
Unfortunately those compile-time settings do not affect the
documentation, so the uninitiated user who tries to understand git by
reading the git-var(1) manpage can easily be confused when git falls
back to 'nano' and 'more' instead of 'vi' and 'less'. Even if the
distributor patches the distributed docs to reflect the new default,
the user may read the official documentation from the git-htmldocs
repository online and be confused in the same way.
Add a few words stating that the defaults are customizable at
compile time to make the behavior crystal clear.

When using this option git will search for all submodules that
have changed in the revisions to be send. It will then try to
push the currently checked out branch of each submodule.
This helps when a user has finished working on a change which
involves submodules and just wants to push everything in one go.

Previously it was not possible to iterate revisions twice using the
revision walking api. We add a reset_revision_walk() which clears the
used flags. This allows us to do multiple sequencial revision walks.
We add the appropriate calls to the existing submodule machinery doing
revision walks. This is done to avoid surprises if future code wants to
call these functions more than once during the processes lifetime.

Why not just git grep -E ...?
