618374930a send-email: initial_to and initial_reply_to are both optional
We may pick up additional recipients from the format-patch output
files we are sending, in which case it is perfectly valid to leave
the @initial_to empty when the prompt asks.  We may want to start
a new discussion thread without replying to anything, and it is
valid to leave $initial_reply_to empty.

An earlier update to avoid y@example.com stuffed in address fields
did not take these two cases into account.

e17dba8fe1 remote: prefer subcommand name 'remove' to 'rm'
All remote subcommands are spelled out words except 'rm'. 'rm', being a
popular UNIX command name, may mislead users that there are also 'ls' or
'mv'. Use 'remove' to fit with the rest of subcommands.

'rm' is still supported and used in the test suite. It's just not
widely advertised.

70b67b0792 cvsimport: strip all inappropriate tag strings
Certain characters such as "?" can be present in a CVS tag name, but
git does not allow these characters in tags. If git-cvsimport
encounters a CVS tag that git cannot handle, cvsimport will error and
refuse to continue the import beyond that point.

When importing CVS tags, strip all the inappropriate strings from the
tag names as we translate them to git tag names.

Provide more debugging information to the user if we've altered the
tag and the "git tag" command still fails. Also, warn the user if we
end up skipping an (unusable) tag altogether.

2162bd8cc4 archive-zip: support UTF-8 paths
Set general purpose flag 11 if we encounter a path that contains
non-ASCII characters.  We assume that all paths are given as UTF-8; no
conversion is done.

The flag seems to be ignored by unzip unless we also mark the archive
entry as coming from a Unix system.  This is done by setting the field
creator_version ("version made by" in the standard[1]) to 0x03NN.

The NN part represents the version of the standard supported by us, and
this patch sets it to 3f (for version 6.3) for Unix paths.  We keep
creator_version set to 0 (FAT filesystem, standard version 0) in the
non-special cases, as before.

But when we declare a file to have a Unix path, then we have to set the
file mode as well, or unzip will extract the files with the permission
set 0000, i.e. inaccessible by all.

5c44252e13 path.c: Use vsnpath() in the implementation of git_path()
The current implementation of git_path() is essentially the same as
that of vsnpath(), with two minor differences. First, git_path()
currently insists that the git directory path is no longer than
PATH_MAX-100 characters in length. However, vsnpath() does not
attempt this arbitrary 100 character reservation for the remaining
path components. Second, vsnpath() uses the "is_dir_sep()" macro,
rather than comparing directly to '/', to determine if the git_dir
path component ends with a path separator.

In order to benefit from the above improvements, along with increased
compatability with git_snpath() and git_pathdup(), we reimplement the
git_path() function using vsnpath().

66a51a9aae path.c: Don't discard the return value of vsnpath()
The git_snpath() and git_pathdup() functions both use the (static)
function vsnpath() in their implementation. Also, they both discard
the return value of vsnpath(), which has the effect of ignoring the
side effect of calling cleanup_path() in the non-error return path.

In order to ensure that the required cleanup happens, we use the
pointer returned by vsnpath(), rather than the buffer passed into
vsnpath(), to derive the return value from git_snpath() and
git_pathdup().

50d89ad654 submodule: use argv_array instead of hand-building arrays
fetch_populated_submodules() allocates the full argv array it uses to
recurse into the submodules from the number of given options plus the six
argv values it is going to add. It then initializes it with those values
which won't change during the iteration and copies the given options into
it. Inside the loop the two argv values different for each submodule get
replaced with those currently valid.

However, this technique is brittle and error-prone (as the comment to
explain the magic number 6 indicates), so let's replace it with an
argv_array. Instead of replacing the argv values, push them to the
argv_array just before the run_command() call (including the option
separating them) and pop them from the argv_array right after that.

85556d4e37 fetch: use argv_array instead of hand-building arrays
Fetch invokes itself recursively when recursing into
submodules or handling "fetch --multiple". In both cases, it
builds the child's command line by pushing options onto a
statically-sized array. In both cases, the array is
currently just big enough to handle the largest possible
case. However, this technique is brittle and error-prone, so
let's replace it with a dynamic argv_array.

ba4d1c7b16 argv-array: fix bogus cast when freeing array
Since the array struct stores a "const char **" argv member
(for compatibility with most of our argv-taking functions),
we have to cast away the const-ness when freeing its
elements.

However, we used the wrong type when doing so.  It doesn't
make a difference since free() take a void pointer anyway,
but it can be slightly confusing to a reader.

fe4a0a2888 argv-array: add pop function
Sometimes we build a set of similar command lines, differing
only in the final arguments (e.g., "fetch --multiple"). To
use argv_array for this, you have to either push the same
set of elements repeatedly, or break the abstraction by
manually manipulating the array's internal members.

Instead, let's provide a sanctioned "pop" function to remove
elements from the end.

46d98476cf t3300-*.sh: Fix a TAP parse error
At present, running the t3300-*.sh test on cygwin looks like:

    $ cd t
    $ ./t3300-funny-names.sh
    ok 1 - setup
    # passed all 1 test(s)
    1..1 # SKIP Your filesystem does not allow tabs in filenames
    $

Unfortunately, this is not valid TAP output, which prove notes
as follows:

    $ prove --exec sh t3300-funny-names.sh
    t3300-funny-names.sh .. All 1 subtests passed

    Test Summary Report
    -------------------
    t3300-funny-names.sh (Wstat: 0 Tests: 1 Failed: 0)
      Parse errors: No plan found in TAP output
    Files=1, Tests=1,  2 wallclock secs ( 0.05 usr  0.00 sys +  \
        0.90 cusr  0.49 csys =  1.43 CPU)
    Result: FAIL
    $

This is due to the 'trailing_plan' having a 'skip_directive'
attached to it. This is not allowed by the TAP grammar, which
only allows a 'leading_plan' to be followed by an optional
'skip_directive'. (see perldoc TAP::Parser::Grammar).

A trailing_plan is one that appears in the TAP output after one or
more test status lines (that start 'not '? 'ok ' ...), whereas a
leading_plan must appear before all test status lines (if any).

In practice, this means that the test script cannot contain a use
of the 'skip all' facility:

    skip_all='Some reason to skip *all* tests in this file'
    test_done

after having already executed one or more tests with (for example)
'test_expect_success'. Unfortunately, this is exactly what this
test script is doing. The first 'setup' test is actually used to
determine if the test prerequisite is satisfied by the filesystem
(ie does it allow tabs in filenames?).

In order to fix the parse errors, place the code to determine the
test prerequisite at the top level of the script, prior to the
first test, rather than as a parameter to test_expect_success.
This allows us to correctly use 'skip_all', thus:

    $ ./t3300-funny-names.sh
    # passed all 0 test(s)
    1..0 # SKIP Your filesystem does not allow tabs in filenames
    $

    $ prove --exec sh t3300-funny-names.sh
    t3300-funny-names.sh .. skipped: Your filesystem does not \
        allow tabs in filenames

from "reference" by simply looking at its object flag, instead of
iterating over the merge bases.

da1f515641 merge_bases_many(): split out the logic to paint history
Introduce a new helper function paint_down_to_common() that takes
the same parameters as merge_bases_many(), but without the first
optimization of not painting anything when "one" is one of the
"twos" (or vice versa), and the last clean-up of removing the common
ancestor that is known to be an ancestor of another common one.

This way, the caller of the new function could tell if "one" is
reachable from any of the "twos" by simply looking at the flag bits
of "one".  If (and only if) it is painted in PARENT2, it is
reachable from one of the "twos".

a73e22e963 cherry-pick/revert: respect order of revisions to pick
When giving multiple individual revisions to cherry-pick or revert, as
in 'git cherry-pick A B' or 'git revert B A', one would expect them to
be picked/reverted in the order given on the command line. They are
instead ordered by their commit timestamp -- in chronological order
for "cherry-pick" and in reverse chronological order for
"revert". This matches the order in which one would usually give them
on the command line, making this bug somewhat hard to notice. Still,
it has been reported at least once before [1].

It seems like the chronological sorting happened by accident because
the revision walker has traditionally always sorted commits in reverse
chronological order when rev_info.no_walk was enabled. In the case of
'git revert B A' where B is newer than A, this sorting is a no-op. For
'git cherry-pick A B', the sorting would reverse the arguments, but
because the sequencer also flips the rev_info.reverse flag when
picking (as opposed to reverting), the end result is a chronological
order. The rev_info.reverse flag was probably flipped so that the
revision walker emits B before C in 'git cherry-pick A..C'; that it
happened to effectively undo the unexpected sorting done when not
walking, was probably a coincidence that allowed this bug to happen at
all.

Fix the bug by telling the revision walker not to sort the commits
when not walking. The only case we want to reverse the order is now
when cherry-picking and walking revisions (rev_info.no_walk = 0).

Cherry-picking commits out of order (w.r.t. commit time stamp) doesn't
currently work. Add a test case to demonstrate it.

ca92e59e30 teach log --no-walk=unsorted, which avoids sorting
When 'git log' is passed the --no-walk option, no revision walk takes
place, naturally. Perhaps somewhat surprisingly, however, the provided
revisions still get sorted by commit date. So e.g 'git log --no-walk
HEAD HEAD~1' and 'git log --no-walk HEAD~1 HEAD' give the same result
(unless the two revisions share the commit date, in which case they
will retain the order given on the command line). As the commit that
introduced --no-walk (8e64006 (Teach revision machinery about
--no-walk, 2007-07-24)) points out, the sorting is intentional, to
allow things like

 git log --abbrev-commit --pretty=oneline --decorate --all --no-walk

to show all refs in order by commit date.

But there are also other cases where the sorting is not wanted, such
as

 <command producing revisions in order> |
       git log --oneline --no-walk --stdin

To accomodate both cases, leave the decision of whether or not to sort
up to the caller, by allowing --no-walk={sorted,unsorted}, defaulting
to 'sorted' for backward-compatibility reasons.

b347d06bf0 branch: deprecate --set-upstream and show help if we detect possible mistaken use
This interface is error prone, and a better one (--set-upstream-to)
exists. Add a message listing the alternatives and suggest how to fix
a --set-upstream invocation in case the user only gives one argument
which causes a local branch with the same name as a remote-tracking
one to be created. The typical case is

    git branch --set-upstream origin/master

when the user meant

    git branch --set-upstream master origin/master

assuming that the current branch is master. Show a message telling the
user how to undo their action and get what they wanted. For the
command above, the message would be

The --set-upstream flag is deprecated and will be removed. Consider using --track or --set-upstream-to
Branch origin/master set up to track local branch master.

If you wanted to make 'master' track 'origin/master', do this:

    git branch -d origin/master
    git branch --set-upstream-to origin/master
