We use git_getpass to retrieve the username and password
from the terminal. However, git_getpass will not echo the
username as the user types. We can fix this by using the
more generic git_prompt, which underlies git_getpass but
lets us specify an "echo" option.

This is like "cache", except that we actually put the
credentials on disk. This can be terribly insecure, of
course, but we do what we can to protect them by filesystem
permissions, and we warn the user in the documentation.
This is not unlike using .netrc to store entries, but it's a
little more user-friendly. Instead of putting credentials in
place ahead of time, we transparently store them after
prompting the user for them once.

When we need to prompt the user for input interactively, we
want to access their terminal directly. We can't rely on
stdio because it may be connected to pipes or files, rather
than the terminal. Instead, we use "getpass()", because it
abstracts the idea of prompting and reading from the
terminal. However, it has some problems:
1. It never echoes the typed characters, which makes it OK
for passwords but annoying for other input (like usernames).
2. Some implementations of getpass() have an extremely
small input buffer (e.g., Solaris 8 is reported to
support only 8 characters).
3. Some implementations of getpass() will fall back to
reading from stdin (e.g., glibc). We explicitly don't
want this, because our stdin may be connected to a pipe
speaking a particular protocol, and reading will
disrupt the protocol flow (e.g., the remote-curl
helper).
4. Some implementations of getpass() turn off signals, so
that hitting "^C" on the terminal does not break out of
the password prompt. This can be a mild annoyance.
Instead, let's provide an abstract "git_terminal_prompt"
function that addresses these concerns. This patch includes
an implementation based on /dev/tty, enabled by setting
HAVE_DEV_TTY. The fallback is to use getpass() as before.

When we try to "git mv" over an existing file, the error
message is fairly informative:

When the user forces the overwrite, we give a warning:

This is less informative, but still sufficient in the simple
rename case, as there is only one rename happening.
But when moving files from one directory to another, it

revert: do not remove state until sequence is finished
As v1.7.8-rc0~141^2~4 (2011-08-04) explains, git cherry-pick removes
the sequencer state just before applying the final patch. In the
single-pick case, that was a good thing, since --abort and --continue
work fine without access to such state and removing it provides a
signal that git should not complain about the need to clobber it ("a
cherry-pick or revert is already in progress") in sequences like the
following:
git cherry-pick foo
git read-tree -m -u HEAD; # forget that; let's try a different one
git cherry-pick bar
After the recent patch "allow single-pick in the middle of cherry-pick
sequence" we don't need that hack any more. In the new regime, a
traditional "git cherry-pick <commit>" command never looks at
.git/sequencer, so we do not need to cripple "git cherry-pick
<commit>..<commit>" for it any more.
So now you can run "git cherry-pick --abort" near the end of a
multi-pick sequence and it will abort the entire sequence, instead of
misbehaving and aborting just the final commit.

revert: pass around rev-list args in already-parsed form
Since 7e2bfd3f (revert: allow cherry-picking more than one commit,

Future callers as other commands are built in (am, rebase, sequencer)

revert: allow cherry-pick --continue to commit before resuming
When "git cherry-pick ..bar" encounters conflicts, permit the operator
to use cherry-pick --continue after resolving them as a shortcut for
"git commit && git cherry-pick --continue" to record the resolution
and carry on with the rest of the sequence.
This improves the analogy with "git rebase" (in olden days --continue
was the way to preserve authorship when a rebase encountered
conflicts) and fits well with a general UI goal of making "git cmd
--continue" save humans the trouble of deciding what to do next.
Example: after encountering a conflict from running "git cherry-pick
foo bar baz":
CONFLICT (content): Merge conflict in main.c
error: could not apply f78a8d98c... bar!
hint: after resolving the conflicts, mark the corrected paths
hint: with 'git add <paths>' or 'git rm <paths>'
hint: and commit the result with 'git commit'
We edit main.c to resolve the conflict, mark it acceptable with "git
add main.c", and can run "cherry-pick --continue" to resume the
sequence.
This was slightly less confusing, because it at least
mentions that there are two ways to invoke (but it still
isn't clear why what the user provided doesn't work).
Instead, let's show an error message like:
$ git mv one two three
fatal: destination 'three' is not a directory
We could leave the usage message in place, too, but it
doesn't actually help here. It contains no hints that there
are two forms, nor that multi-file form requires that the
endpoint be a directory. So it just becomes useless noise
that distracts from the real error.

If you define SNPRINTF_RETURNS_BOGUS, we use a special

However, this means we evaluate the va_list parameter
multiple times, which is generally a bad thing (it may be

credential: make relevance of http path configurable
When parsing a URL into a credential struct, we carefully
record each part of the URL, including the path on the
remote host, and use the result as part of the credential
context.
This had two practical implications:
1. Credential helpers which store a credential for later
access are likely to use the "path" portion as part of
the storage key. That means that a request to
https://example.com/foo.git
would not use the same credential that was stored in an
earlier request for:
https://example.com/bar.git
2. The prompt shown to the user includes all relevant
context, including the path.
In most cases, however, users will have a single password
per host. The behavior in (1) will be inconvenient, and the
prompt in (2) will be overly long.
This patch introduces a config option to toggle the
relevance of http paths. When turned on, we use the path as
before. When turned off, we drop the path component from the
context: helpers don't see it, and it does not appear in the
prompt.
This is nothing you couldn't do with a clever credential
helper at the start of your stack, like:
is way easier and more readable. Furthermore, since most
users will want the "off" behavior, that is the new default.
Users who want it "on" can set the variable (either for all
credentials, or just for a subset using
credential.*.useHttpPath).

Credential helpers can help users avoid having to type their
username and password over and over. However, some users may

a helper which caches for a short time. In this case, it is

their credential via config.

The functionality for credential storage helpers is already
there; we just need to give the users a way to turn it on.
This patch provides a "credential.helper" configuration
variable which allows the user to provide one or more helper
strings.
Rather than simply matching credential.helper, we will also
compare URLs in subsection headings to the current context.
This means you can apply configuration to a subset of
credentials. For example:
[credential "https://example.com"]
helper = foo
would match a request for "https://example.com/foo.git", but
not one for "https://kernel.org/foo.git".
This is overkill for the "helper" variable, since users are
unlikely to want different helpers for different sites (and
since helpers run arbitrary code, they could do the matching
themselves anyway).
However, future patches will add new config variables where
this extra feature will be more useful.

This patch converts the http code to use the new credential
API, both for http authentication as well as for getting
certificate passwords.
Most of the code change is simply variable naming (the
passwords are now contained inside the credential struct)
or deletion of obsolete code (the credential code handles
URL parsing and prompting for us).
The behavior should be the same, with one exception: the
credential code will prompt with a description based on the
credential components. Therefore, the old prompt of:
Username for 'example.com':
Password for 'example.com':
now looks like:
Username for 'https://example.com/repo.git':
Password for 'https://user@example.com/repo.git':
Note that we include more information in each line,
specifically:
1. We now include the protocol. While more noisy, this is
an important part of knowing what you are accessing
(especially if you care about http vs https).
2. We include the username in the password prompt. This is
not a big deal when you have just been prompted for it,
but the username may also come from the remote's URL
(and after future patches, from configuration or
credential helpers). In that case, it's a nice
reminder of the user for which you're giving the
password.
3. We include the path component of the URL. In many
cases, the user won't care about this and it's simply
noise (i.e., they'll use the same credential for a
whole site). However, that is part of a larger
question, which is whether path components should be
part of credential context, both for prompting and for
lookup by storage helpers. That issue will be addressed
as a whole in a future patch.
Similarly, for unlocking certificates, we used to say:
Certificate Password for 'example.com':
and we now say:
Password for 'cert:///path/to/certificate':
Showing the path to the client certificate makes more sense,
as that is what you are unlocking, not "example.com".

We want to be able to turn URLs into broken-down credential
structs so that we know two things:
1. Which parts of the username/password we still need
2. What the context of the request is (for prompting or
as a key for storing credentials).
This code is based on http_auth_init in http.c, but needed a
few modifications in order to get all of the components that
the credential object is interested in.
Once the http code is switched over to the credential API,
then http_auth_init can just go away.

There are a few places in git that need to get a username
and password credential from the user; the most notable one
is HTTP authentication for smart-http pushing.
Right now the only choices for providing credentials are to
put them plaintext into your ~/.netrc, or to have git prompt
you (either on the terminal or via an askpass program). The
former is not very secure, and the latter is not very
convenient.
Unfortunately, there is no "always best" solution for
password management. The details will depend on the tradeoff
you want between security and convenience, as well as how
git can integrate with other security systems (e.g., many
operating systems provide a keychain or password wallet for
single sign-on).
This patch provides an abstract notion of credentials as a
data item, and provides three basic operations:
- fill (i.e., acquire from external storage or from the
user)
- approve (mark a credential as "working" for further
storage)
- reject (mark a credential as "not working", so it can
be removed from storage)
These operations can be backed by external helper processes
that interact with system- or user-specific secure storage.

The old "git symbolic-ref" manpage seemed to imply in one place that
symlinks are still the default way to represent symbolic references
and in another that symlinks are deprecated. Fix the text and shorten
the justification for the change of implementation.

git-gui: Set both 16x16 and 32x32 icons on X to pacify Xming.
It would be better if the 32x32 icon was equivalent to the one used on
Windows (in git-gui.ico), but I'm not sure how that would best be done,
so I copied this code from gitk instead.

In the case of --mixed and --hard, we throw away the old index and
rebuild everything from the tree argument (or HEAD). So we have an
opportunity here to fill in the cache-tree data, just as read-tree
did.

commit: write cache-tree data when writing index anyway
In prepare_index(), we refresh the index, and then write it to disk if
this changed the index data. After running hooks we re-read the index
and compute the root tree sha1 with the cache-tree machinery.
This gives us a mostly free opportunity to write up-to-date cache-tree
data: we can compute it in prepare_index() immediately before writing
the index to disk.
If we do this, we were going to write the index anyway, and the later
cache-tree update has no further work to do. If we don't do it, we
don't do any extra work, though we still don't have have cache-tree
data after the commit.
The only case that suffers badly is when the pre-commit hook changes
many trees in the index. I'm writing this off as highly unusual.

We'll need to safely create or update the cache-tree data of the_index
from other places. While at it, give it an argument that lets us
silence the messages produced by unmerged entries (which prevent it
from working).

Test the current state of the cache-tree optimization
The cache-tree optimization originally helped speed up write-tree
operation. However, many commands no longer properly maintain -- or
use an opportunity to cheaply generate -- the cache-tree data. In
particular, this affects commit, checkout and reset. The notable
examples that *do* write cache-tree data are read-tree and write-tree.
This sadly means most people no longer benefit from the optimization,
as they would not normally use the plumbing commands.
Document the current state of affairs in a test file, in preparation
for improvements in the area.

A simple utility that invalidates all existing cache-tree data. We
need this for tests. (We don't need a tool to rebuild the cache-tree
data; git read-tree HEAD works for that.)

checkout -m: no need to insist on having all 3 stages
The content level merge machinery ll_merge() is prepared to merge
correctly in "both sides added differently" case by using an empty blob as
if it were the common ancestor. "checkout -m" could do the same, but didn't
bother supporting it and instead insisted on having all three stages.

Sockets may never receive notification of some link errors,
causing "git fetch" or similar processes to hang forever.
Enabling keepalive messages allows hung processes to error out
after a few minutes/hours depending on the keepalive settings of
the system.
This is a problem noticed when running non-interactive
cronjobs to mirror repositories using "git fetch".

i18n: add infrastructure for translating Git with gettext
Change the skeleton implementation of i18n in Git to one that can show
localized strings to users for our C, Shell and Perl programs using
either GNU libintl or the Solaris gettext implementation.
This new internationalization support is enabled by default. If
gettext isn't available, or if Git is compiled with
NO_GETTEXT=YesPlease, Git falls back on its current behavior of
showing interface messages in English. When using the autoconf script
we'll auto-detect if the gettext libraries are installed and act
appropriately.
This change is somewhat large because as well as adding a C, Shell and
Perl i18n interface we're adding a lot of tests for them, and for
those tests to work we need a skeleton PO file to actually test
translations. A minimal Icelandic translation is included for this
purpose. Icelandic includes multi-byte characters which makes it easy
to test various edge cases, and it's a language I happen to
understand.
The rest of the commit message goes into detail about various
sub-parts of this commit.
= Installation
Gettext .mo files will be installed and looked for in the standard
$(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to
override that, but that's only intended to be used to test Git itself.
= Perl
Perl code that's to be localized should use the new Git::I18n
module. It imports a __ function into the caller's package by default.
Instead of using the high level Locale::TextDomain interface I've
opted to use the low-level (equivalent to the C interface)
Locale::Messages module, which Locale::TextDomain itself uses.
Locale::TextDomain does a lot of redundant work we don't need, and
some of it would potentially introduce bugs. It tries to set the
$TEXTDOMAIN based on package of the caller, and has its own
hardcoded paths where it'll search for messages.
I found it easier just to completely avoid it rather than try to
circumvent its behavior. In any case, this is an issue wholly
internal Git::I18N. Its guts can be changed later if that's deemed
necessary.
See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com> for
a further elaboration on this topic.
= Shell
Shell code that's to be localized should use the git-sh-i18n
library. It's basically just a wrapper for the system's gettext.sh.
If gettext.sh isn't available we'll fall back on gettext(1) if it's
available. The latter is available without the former on Solaris,
which has its own non-GNU gettext implementation. We also need to
emulate eval_gettext() there.
If neither are present we'll use a dumb printf(1) fall-through
wrapper.
= About libcharset.h and langinfo.h
We use libcharset to query the character set of the current locale if
it's available. I.e. we'll use it instead of nl_langinfo if
HAVE_LIBCHARSET_H is set.
The GNU gettext manual recommends using langinfo.h's
nl_langinfo(CODESET) to acquire the current character set, but on
systems that have libcharset.h's locale_charset() using the latter is
either saner, or the only option on those systems.
GNU and Solaris have a nl_langinfo(CODESET), FreeBSD can use either,
but MinGW and some others need to use libcharset.h's locale_charset()
instead.

resolve_ref() may return a pointer to a static buffer. Callers that
use this value longer than a couple of statements should copy the
value to avoid some hidden resolve_ref() call that may change the
static buffer's value.
The bug found by Tony Wang <wwwjfy@gmail.com> in builtin/merge.c
demonstrates this. The first call is in cmd_merge()
