revision traversal and pack: notice and die on missing commit
cc0e6c5 (Handle return code of parse_commit in revision machinery,
2007-05-04) attempted to tighten error checking in the revision machinery,
but it wasn't enough. When get_revision_1() was asked for the next commit
to return, it tries to read and simplify the parents of the commit to be
returned, but an error while doing so was silently ignored and reported as
a truncated history to the caller instead.
This resulted in an early end of "git log" output or a pack that lacks
older commits from "git pack-objects", without any error indication in the
exit status from these commands, even though the underlying parse_commit()
issues an error message to the end user.
Note that the codepath in add_parents_list() that paints parents of an
UNINTERESTING commit UNINTERESTING silently ignores the error when
parse_commit() fails; this is deliberate and in line with aeeae1b
(revision traversal: allow UNINTERESTING objects to be missing,
2009-01-27).
Jakub says that legacy-style URI to view two blob differences are never
generated since 1.4.3. This codepath runs "git diff" Porcelain from the
gitweb, which is a no-no. It can trigger diff.external command that is
specified in the configuration file of the repository being viewed.
This is a backport of 0a47dc110e042b5bcc63dc94c8d517e67efe9306
to 'maint' to be included in 1.5.6.2 so that older server side
can accept dashless form of request when clients are updated.
It worked that way since commit 50f575fc (Tweak diff colors,
2006-06-22), but commit c1795bb0 (Unify whitespace checking, 2007-12-13)
changed it. This patch restores the old behaviour.
Besides Linus' arguments in the log message of 50f575fc, resetting color
before printing newline is also important to keep 'git add --patch'
happy. If the last line(s) of a file are removed, then that hunk will
end with a colored line. However, if the newline comes before the color
reset, then the diff output will have an additional line at the end
containing only the reset sequence. This causes trouble in
git-add--interactive.perl's parse_diff function, because @colored will
have one more element than @diff, and that last element will contain the
color reset. The elements of these arrays will then be copied to @hunk,
but only as many as the number of elements in @diff. As a result the
last color reset is lost and all subsequent terminal output will be
printed in color.

commit --interactive: properly update the index before commiting
When adding files through git commit --interactive, and 'quit'
afterwards, the message in the editor of the commit message indicates
that many (maybe all) files are deleted from the tree. Dismissing that
and running git commit afterwards does the right thing. This commit
fixes git commit --interactive to properly update the index before
commiting.

where B and C modify a path, X, in the same way so that the result is
identical, and D does not modify it at all. With the path limiter X and
without --full-history this is simplified to
A--B
i.e. only one of the paths via B or C is chosen. I had assumed that
--full-history would keep both paths like this
C--M
/ /
A--B
removing the path via D; but in fact it keeps the entire history.
Currently, git does not have the capability to simplify to this
intermediary case. However, the other extreme to keep the entire history
is not wanted either in usual cases. I think we can expect that histories
like the above are rare, and in the usual cases we want a simplified
history. So let's remove --full-history again.
(Concerning t7003, subsequent tests depend on what the test case sets up,
so we can't just back out the entire test case.)

checkout: don't rfc2047-encode oneline on detached HEAD
When calling pretty_print_commit, there is an implicit

This is not the desired effect when reporting the movement

We never actually munge the string itself, but instead keep
offsets into the string with their associated lengths.
When we call approxidate on the contents inside braces,
however, we pass just a string without a length. This means
that approxidate could sometimes look past the closing brace
and (erroneously) interpret the rest of the string as part
of the date.

fetch-pack: do not stop traversing an already parsed commit
f3ec549 (fetch-pack: check parse_commit/object results, 2008-03-03)
broke common ancestor computation by stopping traversal when it sees
an already parsed commit. This should fix it.
1. check for an unambiguous 'dst' on the remote; if it
exists, then push to that ref
2. otherwise, check if 'dst' begins with 'refs/'; if it
does, create a new ref
3. otherwise, complain because we don't know where in the
refs hierarchy to put 'dst'
However, in some cases, we can guess about the ref type of
'dst' based on the ref type of 'src'. Specifically, before
complaining we now check:
2.5. if 'src' resolves to a ref starting with refs/heads
or refs/tags, then prepend that to 'dst'
So now this creates a new branch on the remote, whereas it
previously failed with an error message:
git push master:newbranch
Note that, by design, we limit this DWIM behavior only to
source refs which resolve exactly (including symrefs which
resolve to existing refs). We still complain on a partial
destination refspec if the source is a raw sha1, or a ref
expression such as 'master~10'.

gitweb: Fix 'history' view for deleted files with history
When asked for history of a file which is not present in given branch
("HEAD", i.e. current branch, or given by transient $hash_hase ('hb')
parameter), but is present deeper in the history (meaning that "git
rev-list --full-history $hash_base -- $file_name" is not empty), and
there is no $hash ('h') parameter set for a file, gitweb would spew
multiple of "Use of uninitialized value" warnings, and some links
would be missing. This commit fixes this bug.
This bug occurs in the rare cases when "git log -- <path>" is empty
and "git log --full-history -- <path>" is not, or to be more exact in
the cases when full-history starts later than given branch. It can
happen if you are using handcrafted gitwb URL, or if you follow
generic 'history' link or bookmark for a file which got deleted.
Gitweb tried to get file type ('tree', or 'blob', or even 'commit')
from the commit we start searching from (where the file was not
present), and not among found commits. This was the cause of "Use of
uninitialized value" warnings.
This commit also add tests for such situation to t9500 test.
While we are it, return HTTP error if there is _no_ history; it means
that file or directory was not found (for given branch). Also error
out if type of item could not be found: it should not happen now, but
better be sure.
