4ed115e9c5 cache-tree: do not try to use an invalidated subtree info to build a tree
We punt from repairing the cache-tree during a branch switching if
it involves having to create a new tree object that does not yet
exist in the object store.  "mkdir dir && >dir/file && git add dir"
followed by "git checkout" is one example, when a tree that records
the state of such "dir/" is not in the object store.

However, after discovering that we do not have a tree object that
records the state of "dir/", the caller failed to remember the fact
that it noticed the cache-tree entry it received for "dir/" is
invalidated, it already knows it should not be populating the level
that has "dir/" as its immediate subdirectory, and it is not an
error at all for the sublevel cache-tree entry gave it a bogus
object name it shouldn't even look at.

This led the caller to detect and report a non-existent error.  The
end result was the same and we avoided stuffing a non-existent tree
to the cache-tree, but we shouldn't have issued an alarming error
message to the user.

9c4d6c0297 cache-tree: Write updated cache-tree after commit
During the commit process, update the cache-tree. Write this updated
cache-tree so that it's ready for subsequent commands.

Add test code which demonstrates that git commit now writes the cache
tree.  Make all tests test the entire cache-tree, not just the root
level.

aecf567cbf cache-tree: create/update cache-tree on checkout
When git checkout checks out a branch, create or update the
cache-tree so that subsequent operations are faster.

update_main_cache_tree learned a new flag, WRITE_TREE_REPAIR.  When
WRITE_TREE_REPAIR is set, portions of the cache-tree which do not
correspond to existing tree objects are invalidated (and portions which
do are marked as valid).  No new tree objects are created.

45067fc973 t7300: repair filesystem permissions with test_when_finished
We create a directory that cannot be removed, confirm that
it cannot be removed, and then fix it like:

  chmod 0 foo &&
  test_must_fail git clean -d -f &&
  chmod 755 foo

If the middle step fails but leaves the directory (e.g., the
bug is that clean does not notice the failure), this
pollutes the test repo with an unremovable directory. Not
only does this cause further tests to fail, but it means
that "rm -rf" fails on the whole trash directory, and the
user has to intervene manually to even re-run the test script.

We can bump the "chmod 755" recovery to a test_when_finished
block to be sure that it always runs.

    git shortlog

However, the latter does not understand the ref-exclusion command
line option, even though other options understood by "log", such as
"--all" and "--no-merges", are understood.

This was because e7b432c5 (revision: introduce --exclude=<glob> to
tame wildcards, 2013-08-30) did not wire the new option fully to the
machinery.  A new option understood by handle_revision_pseudo_opt()

c8e1ee4f2c update-index: fix segfault with missing --cacheinfo argument
Running "git update-index --cacheinfo" without any further
arguments results in a segfault rather than an error

examine the format of the argument, but forgot to handle the

Returning an error from the parser is enough, since we then
treat it as an old-style "--cacheinfo <mode> <sha1> <path>",
and complain that we have less than 3 arguments to read.

afa53fe5d1 t5538: move http push tests out to t5542
As 0232852b, but for the push tests instead: this avoids a start_httpd
in the middle of the file, which fails under GIT_TEST_HTTPD=false.

Note that we have to munge the test in a few ways while
moving it:

  1. We drop the `test -z "$GIT_TEST_HTTPD"` check; this is
     too simplistic since 83d842d, and we should let
     lib-httpd.sh handle it.

  2. We have to port over some of the old setup from t5538.

  3. In the final test, we no longer expect the extra commit
     "1" built on top of "4". This was a side effect from an
     earlier test in t5538 which was not ported over.

d717282532 t5537: re-drop http tests
These were originally removed by 0232852 (t5537: move
http tests out to t5539, 2014-02-13). However, they were
accidentally re-added in 1ddb4d7 (Merge branch
'nd/upload-pack-shallow', 2014-03-21).

This looks like an error in manual conflict resolution.
Here's what happened:

  1. v1.9.0 shipped with the http tests in t5537.

  2. We realized that this caused problems, and built
     0232852 on top to move the tests to their own file.
     This fix made it into v1.9.1.

  3. We later had another fix in nd/upload-pack-shallow that
     also touched t5537. It was built directly on v1.9.0.

When we merged nd/upload-pack-shallow to master, we got a
conflict; it was built on a version with the http tests, but
we had since removed them. The correct resolution was to
drop the http tests and keep the new ones, but instead we
kept everything.

7d509878b8 pretty.c: format string with truncate respects logOutputEncoding
Pretty format string %<(N,[ml]trunc)>%s truncates subject to a given
length with an appropriate padding. This works for non-ASCII texts when
i18n.logOutputEncoding is UTF-8 only (independently of a printed commit
message encoding) but does not work when i18n.logOutputEncoding is NOT
UTF-8.

In 7e77df3 (pretty: two phase conversion for non utf-8 commits, 2013-04-19)
'format_commit_item' function assumes commit message to be in UTF-8.
And that was so until ecaee80 (pretty: --format output should honor
logOutputEncoding, 2013-06-26) where conversion to logOutputEncoding was
added before calling 'format_commit_message'.

Correct this by converting a commit message to UTF-8 first (as it
assumed in 7e77df3 (pretty: two phase conversion for non utf-8 commits,
2013-04-19)). Only after that convert a commit message to an actual
logOutputEncoding.

Add failing tests for that which will be fixed in the next patch.

The recent updates broke this and in the output we see "for-linus"

5304810044 run_diff_files: do not look at uninitialized stat data
If we try to diff an index entry marked CE_VALID (because it
was marked with --assume-unchanged), we do not bother even
running stat() on the file to see if it was removed. This
started long ago with 540e694 (Prevent diff machinery from
examining assume-unchanged entries on worktree, 2009-08-11).

However, the subsequent code may look at our "struct stat"
and expect to find actual data; currently it will find
whatever cruft was left on the stack. This can cause
problems in two situations:

  1. We call match_stat_with_submodule with the stat data,
     so a submodule may be erroneously marked as changed.

  2. If --find-copies-harder is in effect, we pass all
     entries, even unchanged ones, to diff_change, so it can
     list them as rename/copy sources. Since we found no
     change, we assume that function will realize it and not
     actually display any diff output. However, we end up
     feeding it a bogus mode, leading it to sometimes claim
     there was a mode change.

We can fix both by splitting the CE_VALID and regular code
paths, and making sure only to look at the stat information
in the latter. Furthermore, we push the declaration of our
"struct stat" down into the code paths that actually set it,
so we cannot accidentally access it uninitialized in future
code.

ad2f7255b3 git-show: fix 'git show -s' to not add extra terminator after merge commit
When git show -s is called for merge commit it prints extra newline
after any merge commit. This differs from output for commits with one
parent. Fix it by more thorough checking that diff output is disabled.

The code in question exists since commit 3969cf7db1. The additional
newline is really needed for cases when patch is requested, test
t4013-diff-various.sh contains cases which can demonstrate behavior when
the condition is restricted further.

Tests:

Added merge commit to 'set up a bit of history' case in t7007-show.sh to
cover the fix.

Existing tests are updated to demonstrate the new behaviour.  Earlier,
the tests that used "git show -s --pretty=format:%s", even though
"--pretty=format:%s" calls for item separator semantics and does not ask
for the terminating newline after the last item, expected the output to
end with such a newline.  They were relying on the buggy behaviour.  Use
of "--format=%s", which is equivalent to "--pretty=tformat:%s" that asks
for a terminating newline after each item, is a more realistic way to
use the command.

In the test 'merge log messages' the expected data is changed, because
it was explicitly listing the extra newline. Also the msg.nologff and
msg.nolognoff expected files are replaced by one msg.nolog, because they
were diffing because of the bug, and now there should be no difference.

ae352c7f37 merge-recursive.c: fix case-changing merge bug
On a case-insensitive filesystem, when merging, a file would be
wrongly deleted from the working tree if an incoming commit had
renamed it changing only its case.  When merging a rename, the file
with the old name would be deleted -- but since the filesystem
considers the old name to be the same as the new name, the new
file would in fact be deleted.

We avoid this by not deleting files that have a case-clone in the
index at stage 0.

076cbd6341 commit: do not complain of empty messages from -C
When we pick another commit's message, we die() immediately
if we find that it's empty and we are not going to run an
editor (i.e., when running "-C" instead of "-c").  However,
this check is redundant and harmful.

It's redundant because we will already notice the empty
message later, after we would have run the editor, and die
there (just as we would for a regular, not "-C" case, where
the user provided an empty message in the editor).

It's harmful for a few reasons:

  1. It does not respect --allow-empty-message. As a result,
     a "git rebase -i" cannot "pick" such a commit. So you
     cannot even go back in time to fix it with a "reword"
     or "edit" instruction.

  2. It does not take into account other ways besides the
     editor to modify the message. For example, "git commit
     -C empty-commit -m foo" could take the author
     information from empty-commit, but add a message to it.
     There's more to do to make that work correctly (and
     right now we explicitly forbid "-C with -m"), but this
     removes one roadblock.

  3. The existing check is not enough to prevent segfaults.
     We try to find the "\n\n" header/body boundary in the
     commit. If it is at the end of the string (i.e., no
     body), _or_ if we cannot find it at all (i.e., a
     truncated commit object), we consider the message
     empty. With "-C", that's OK; we die in either case. But
     with "-c", we continue on, and in the case of a
     truncated commit may end up dereferencing NULL+2.

7bbc458b44 t9117: use --prefix "" instead of --prefix=""
Versions of Perl's Getopt::Long module before 2.37 do not contain
this fix that first appeared in Getopt::Long version 2.37:

* Bugfix: With gnu_compat, --foo= will no longer trigger "Option
  requires an argument" but return the empty string.

Instead of using --prefix="" use --prefix "" when testing an
explictly empty prefix string in order to work with older versions
of Perl's Getopt::Long module.

Also add a paragraph on this workaround to the documentation of
git-svn itself.

8976500cbb git-prompt.sh: don't put unsanitized branch names in $PS1
Both bash and zsh subject the value of PS1 to parameter expansion,
command substitution, and arithmetic expansion.  Rather than include
the raw, unescaped branch name in PS1 when running in two- or
three-argument mode, construct PS1 to reference a variable that holds
the branch name.  Because the shells do not recursively expand, this
avoids arbitrary code execution by specially-crafted branch names such
as '$(IFS=_;cmd=sudo_rm_-rf_/;$cmd)'.

fe191fcaa5 Git 2.0: git svn: Set default --prefix='origin/' if --prefix is not given
git-svn by default puts its Subversion-tracking refs directly in
refs/remotes/*. This runs counter to Git's convention of using
refs/remotes/$remote/* for storing remote-tracking branches.

Furthermore, combining git-svn with regular git remotes run the risk of
clobbering refs under refs/remotes (e.g. if you have a git remote
called "tags" with a "v1" branch, it will overlap with the git-svn's
tracking branch for the "v1" tag from Subversion.

Even though the git-svn refs stored in refs/remotes/* are not "proper"
remote-tracking branches (since they are not covered by a proper git
remote's refspec), they clearly represent a similar concept, and would
benefit from following the same convention.

For example, if git-svn tracks Subversion branch "foo" at
refs/remotes/foo, and you create a local branch refs/heads/foo to add
some commits to be pushed back to Subversion (using "git svn dcommit),
then it is clearly unhelpful of Git to throw

  warning: refname 'foo' is ambiguous.

every time you checkout, rebase, or otherwise interact with the branch.

The existing workaround for this is to supply the --prefix=quux/ to
git svn init/clone, so that git-svn's tracking branches end up in
refs/remotes/quux/* instead of refs/remotes/*. However, encouraging
users to specify --prefix to work around a design flaw in git-svn is
suboptimal, and not a long term solution to the problem. Instead,
git-svn should default to use a non-empty prefix that saves
unsuspecting users from the inconveniences described above.

This patch will only affect newly created git-svn setups, as the
--prefix option only applies to git svn init (and git svn clone).
Existing git-svn setups will continue with their existing (lack of)
prefix. Also, if anyone somehow prefers git-svn's old layout, they
can recreate that by explicitly passing an empty prefix (--prefix "")
on the git svn init/clone command line.

The patch changes the default value for --prefix from "" to "origin/",
updates the git-svn manual page, and fixes the fallout in the git-svn
testcases.

(Note that this patch might be easier to review using the --word-diff
and --word-diff-regex=. diff options.)
