ac930287ff git-svn: workaround for a bug in svn serf backend
Subversion serf backend in versions 1.8.5 and below has a bug(*) that the
function creating the descriptor of a file change -- add_file() --
doesn't make a copy of its third argument when storing it on the
returned descriptor.  As a result, by the time this field is used (in
transactions of file copying or renaming) it may well be released, and
the memory reused.

One of its possible manifestations is the svn assertion triggering on an
invalid path, with a message

svn_fspath__skip_ancestor: Assertion
`svn_fspath__is_canonical(child_fspath)' failed.

This patch works around this bug, by storing the value to be passed as
the third argument to add_file() in a local variable with the same scope
as the file change descriptor, making sure their lifetime is the same.

* [ew: fixed in Subversion r1553376 as noted by Jonathan Nieder]

a893346930 mv: let 'git mv file no-such-dir/' error out on Windows, too
The previous commit c57f628 (mv: let 'git mv file no-such-dir/' error out)
relies on that rename("file", "no-such-dir/") fails if the directory does not
exist (note the trailing slash).  This does not work as expected on Windows:
This rename() call does not fail, but renames "file" to "no-such-dir" (not to
"no-such-dir/file"). Insert an explicit check for this case to force an error.

This changes the error message from

   $ git mv file no-such-dir/
   fatal: renaming 'file' failed: Not a directory

to

   $ git mv file no-such-dir/
   fatal: destination directory does not exist, source=file, destination=no-such-dir/

ed7eda8b38 gc: notice gc processes run by other users
Since 64a99eb4 git gc refuses to run without the --force option if
another gc process on the same repository is already running.

However, if the repository is shared and user A runs git gc on the
repository and while that gc is still running user B runs git gc on
the same repository the gc process run by user A will not be noticed
and the gc run by user B will go ahead and run.

The problem is that the kill(pid, 0) test fails with an EPERM error
since user B is not allowed to signal processes owned by user A
(unless user B is root).

Update the test to recognize an EPERM error as meaning the process
exists and another gc should not be run (unless --force is given).

e1c1a324fc Revert "prompt: clean up strbuf usage"
This reverts commit 31b49d9b65.

That commit taught do_askpass to hand ownership of our
buffer back to the caller rather than simply return a
pointer into our internal strbuf.  What it failed to notice,
though, was that our internal strbuf is static, because we
are trying to emulate the getpass() interface.

By handing off ownership, we created a memory leak that
cannot be solved. Sometimes git_prompt returns a static
buffer from getpass() (or our smarter git_terminal_prompt
wrapper), and sometimes it returns an allocated string from
do_askpass.

6554dfa97a cat-file: handle --batch format with missing type/size
Commit 98e2092 taught cat-file to stream blobs with --batch,
which requires that we look up the object type before
loading it into memory.  As a result, we now print the
object header from information in sha1_object_info, and the
actual contents from the read_sha1_file. We double-check
that the information we printed in the header matches the
content we are about to show.

Later, commit 93d2a60 allowed custom header lines for
--batch, and commit 5b08640 made type lookups optional. As a
result, specifying a header line without the type or size
means that we will not look up those items at all.

This causes our double-checking to erroneously die with an
error; we think the type or size has changed, when in fact
it was simply left at "0".

For the size, we can fix this by only doing the consistency
double-check when we have retrieved the size via
sha1_object_info. In the case that we have not retrieved the
value, that means we also did not print it, so there is
nothing for us to check that we are consistent with.

We could do the same for the type. However, besides our
consistency check, we also care about the type in deciding
whether to stream or not. So instead of handling the case
where we do not know the type, this patch instead makes sure
that we always trigger a type lookup when we are printing,
so that even a format without the type will stream as we
would in the normal case.

370c9268d1 cat-file: pass expand_data to print_object_or_die
We currently individually pass the sha1, type, and size
fields calculated by sha1_object_info. However, if we pass
the whole struct, the called function can make more
intelligent decisions about which fields were actually
filled by sha1_object_info.

This patch takes that first refactoring step, passing the
whole struct, so further patches can make those decisions
with less noise in their diffs. There should be no
functional change to this patch (aside from a minor typo fix
in the error message).

As a side effect, we can rename the local variables in the
function to "type" and "size", since the names are no longer
taken.

Use a protocol "local" for URLs for the local file system.

One note about using file:// under Windows:

The (absolute) path on Unix like system typically starts with "/".
When the host is empty, it can be omitted, so that a shell scriptlet
url=file://$pwd
will give a URL like "file:///home/user/repo".

Windows does not have the same concept of a root directory located in "/".
When parsing the URL allow "file://C:/user/repo"
(even if RFC1738 indicates that "file:///C:/user/repo" should be used).

The documentation (in urls.txt) says that

    "ssh://host:/~repo",
    "host:/~repo" or
    "host:~repo"

specify the repository "repo" in the home directory at "host".

This has not been working for "host:/~repo".

Before commit 356bec "Support [address] in URLs", the comparison
"url != hostname" could be used to determine if the URL had a scheme
or not: "ssh://host/host" != "host".

However, after 356bec "[::1]" was converted into "::1", yielding
url != hostname as well.  To fix this regression, don't use
"if (url != hostname)", but look at the separator instead.

Rename the variable "c" into "separator" to make it easier to read.

d98d109979 git_connect: remove artificial limit of a remote command
Since day one, function git_connect() had a limit on the command line of
the command that is invoked to make a connection. 7a33bcbe converted the
code that constructs the command to strbuf. This would have been the
right time to remove the limit, but it did not happen. Remove it now.

git_connect() uses start_command() to invoke the command; consequently,
the limits of the system still apply, but are diagnosed only at execve()
time. But these limits are more lenient than the 1K that git_connect()
imposed.

62f162f8e7 rev-parse: be more careful with munging arguments
When rev-parse looks at whether an argument like "foo..bar" or
"foobar^@" is a difference or parent-shorthand, it internally
munges the arguments so that it can pass the individual rev
arguments to get_sha1(). However, we do not consistently un-munge
the result.

For cases where we do not match (e.g., "doesnotexist..HEAD"), we
would then want to try to treat the argument as a filename.
try_difference gets() this right, and always unmunges in this case.
However, try_parent_shorthand() never unmunges, leading to incorrect
error messages, or even incorrect results:

  $ git rev-parse foobar^@
  foobar
  fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree.
  Use '--' to separate paths from revisions, like this:
  'git <command> [<revision>...] -- [<file>...]'

  $ >foobar
  $ git rev-parse foobar^@
  foobar

For cases where we do match, neither function unmunges. This does
not currently matter, since we are done with the argument. However,
a future patch will do further processing, and this prepares for
it. In addition, it's simply a confusing interface for some cases to
modify the const argument, and others not to.

filenames, and that anything after the "--" is taken as-is.
However, it does not understand that anything before the
token must be a revision (which is the usual rule
implemented by the setup_revisions parser).

Since rev-parse prefers revisions to files when parsing
before the "--", we end up with the correct result (if such
an argument is a revision, we parse it as one, and if it is
not, it is an error either way).  However, we misdiagnose
the errors:

  $ git rev-parse foobar -- >/dev/null
  fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree.
  Use '--' to separate paths from revisions, like this:
  'git <command> [<revision>...] -- [<file>...]'

  $ >foobar
  $ git rev-parse foobar -- >/dev/null
  fatal: bad flag '--' used after filename

In both cases, we should know that the real error is that
"foobar" is meant to be a revision, but could not be
resolved.

5594bcad21 clone,fetch: catch non positive --depth option value
Instead of simply ignoring the value passed to --depth option when
it is zero or negative, catch and report it as an error to let
people know that they were using the option incorrectly.

1a72cfd7fa commit -v: strip diffs and submodule shortlogs from the commit message
When using the '-v' option of "git commit" the diff added to the commit
message temporarily for editing is stripped off after the user exited the
editor by searching for "\ndiff --git " and truncating the commmit message
there if it is found.

But this approach has two problems:

- when the commit message itself contains a line starting with
  "diff --git" it will be truncated there prematurely; and

- when the "diff.submodule" setting is set to "log", the diff may
  start with "Submodule <hash1>..<hash2>", which will be left in
  the commit message while it shouldn't.

Fix that by introducing a special scissor separator line starting with the
comment character ('#' or the core.commentChar config if set) followed by
two lines describing what it is for. The scissor line - which will not be
translated - is used to reliably detect the start of the diff so it can be
chopped off from the commit message, no matter what the user enters there.

Turn a known test failure fixed by this change into a successful test;
also add one for a diff starting with a submodule log and another one for
proper handling of the comment char.
