git branch: fix performance problem

'git branch' looks at _all_ the refs, and verifies them.  Which means that
during cold-cache situations with a slow disk (and lots of tags, for
example) it can take several very annoying seconds (7.5s according to a
report by Carlos R.  Mafra).

This avoids most of it by simply doing the filtering before looking up
the commits, by using the "raw" version of for_each_ref.

do_one_ref(): null_sha1 check is not about broken ref

f8948e2 (remote prune: warn dangling symrefs, 2009-02-08) introduced a
more dangerous variant of for_each_ref() family that skips the check for
dangling refs, but it also made another unrelated check optional by
mistake.

The check to see if a ref points at 0{40} is not about brokenness, but is
about a possible future plan to represent a deleted ref by writing 40 "0"
in a loose ref when there is a stale version of the same ref already in
.git/packed-refs, so that we can implement deletion of a ref without
having to rewrite the packed refs file excluding the ref being deleted.

This check has to live outside of the conditional.

Trailing whitespace and no newline fix

If a patch adds a new line to the end of a file and this line ends with
one trailing whitespace character and has no newline, then
'--whitespace=fix' currently does not remove that trailing whitespace.

combine-diff.c: fix performance problem when folding common deleted lines

For a deleted line in a patch with the parent we are looking at, the
append_lost() function finds the same line among a run of lines that were
deleted from the same location by patches from parents we previously

While reading the second patch (that removes "two" and then "fyra"), after
finding where removal of the "two" matches, we need to find existing
removal of "fyra" (if exists) in the removal list, but the match has to
happen after all the existing matches (in this case "two").  The code used
a naïve O(n^2) algorithm to compute this by scanning the whole removal
list over and over again.

This patch remembers where the next scan should be started in the existing
removal list to avoid this.

checkout -f: deal with a D/F conflict entry correctly

When we switch branches with "checkout -f", unpack_trees() feeds two
cache_entries to oneway_merge() function in its src[] array argument.  The
zeroth entry comes from the current index, and the first entry represents
what the merge result should be, taken from the tree recorded in the
commit we are switching to.

When we have a blob (either regular file or a symlink) in the index and in
the work tree at path "foo", and the switched-to tree has "foo/bar",
i.e. "foo" becomes a directory, src[0] is obviously that blob currently
registered at "foo".  Even though we do not have anything at "foo" in the
switched-to tree, src[1] is _not_ NULL in this case.

The unpack_trees() machinery places a special marker df_conflict_entry
to signal that no blob exists at "foo", but it will become a directory
that may have somthing underneath it (namely "foo/bar"), so a usual 3-way
merge can notice the situation.

But oneway_merge() codepath failed to notice this and passed the special
marker directly to merged_entry().  This happens to remove the "foo" in
the end because the df_conflict_entry does not have any name (hence the
"error" message) and its addition in add_index_entry() is rejected, but it
is wrong.

15 years agoFix big left-shifts of unsigned char
Linus Torvalds [Thu, 18 Jun 2009 00:22:27 +0000 (17:22 -0700)]
Fix big left-shifts of unsigned char

Shifting 'unsigned char' or 'unsigned short' left can result in sign
extension errors, since the C integer promotion rules means that the
unsigned char/short will get implicitly promoted to a signed 'int' due to
the shift (or due to other operations).

This normally doesn't matter, but if you shift things up sufficiently, it
will now set the sign bit in 'int', and a subsequent cast to a bigger type
(eg 'long' or 'unsigned long') will now sign-extend the value despite the
original expression being unsigned.

One example of this would be something like

unsigned long size;
unsigned char c;

size += c << 24;

where despite all the variables being unsigned, 'c << 24' ends up being a
signed entity, and will get sign-extended when then doing the addition in
an 'unsigned long' type.

Since git uses 'unsigned char' pointers extensively, we actually have this
bug in a couple of places.

I may have missed some, but this is the result of looking at

git grep '[^0-9  ][  ]*<<[  ][a-z]' -- '*.c' '*.h'
git grep '<<[   ]*24'

which catches at least the common byte cases (shifting variables by a
variable amount, and shifting by 24 bits).

I also grepped for just 'unsigned char' variables in general, and
converted the ones that most obviously ended up getting implicitly cast
immediately anyway (eg hash_name(), encode_85()).

In addition to just avoiding 'unsigned char', this patch also tries to use
a common idiom for the delta header size thing. We had three different
variations on it: "& 0x7fUL" in one place (getting the sign extension
right), and "& ~0x80" and "& 0x7f" in two other places (not getting it
right). Apart from making them all just avoid using "unsigned char" at
all, I also unified them to then use a simple "& 0x7f".

I considered making a sparse extension which warns about doing implicit
casts from unsigned types to signed types, but it gets rather complex very
quickly, so this is just a hack.

fetch-pack: close output channel after sideband demultiplexer terminates

fetch-pack runs the sideband demultiplexer using start_async(). This
facility requires that the asynchronously executed function closes the
output file descriptor (see Documentation/technical/api-run-command.txt).
But the sideband demultiplexer did not do that. This fixes it.

In certain error situations this could lock up a fetch operation on
Windows because the asynchronous function is run in a thread; by not
closing the output fd the reading end never got EOF and waited for more
data indefinitely. On Unix this is not a problem because the asynchronous
function is run in a separate process, which exits after the function ends
and so implicitly closes the output.

Since the pack that is sent over the wire encodes the number of objects in
the stream, during normal operation the reading end knows when the stream
ends and terminates by itself, and does not lock up.

daemon: Strictly parse the "extra arg" part of the command

Since 1.4.4.5 (49ba83fb67 "Add virtualization support to git-daemon")
git daemon enters an infinite loop and never terminates if a client
hides any extra arguments in the initial request line which is not
exactly "\0host=blah\0".

Since that change, a client must never insert additional extra
arguments, or attempt to use any argument other than "host=", as
any daemon will get stuck parsing the request line and will never
complete the request.

Since the client can't tell if the daemon is patched or not, it
is not possible to know if additional extra args might actually be
able to be safely requested.

If we ever need to extend the git daemon protocol to support a new
feature, we may have to do something like this to the exchange:

  # If both support git:// v2
  #
  C: 000cgit://v2
  S: 0010ok host user
  C: 0018host git.kernel.org

  # If client supports git:// v2, server does not:
  #
  C: 000cgit://v2
  S: <EOF>

  C: 003bgit-upload-pack /pub/linux-2.6.git\0host=git.kernel.org\0
  S: ...git-upload-pack header...

This requires the client to create two TCP connections to talk to
an older git daemon, however all daemons since the introduction of
daemon.c will safely reject the unknown "git://v2" command request,
so the client can quite easily determine the server supports an
older protocol.

cat-file with an object on the command line requires an
option to tell it what to output (type, size, pretty-print,
etc). However, the square brackets in the usage imply that
those options are not required. This patch switches them to
parentheses to indicate "required but grouped-OR" (curly
braces might also work, but this follows the convention used
already by "git stash").

While we're at it, let's change the <sha1> specifier in the
usage to <object>. That's what the documentation uses, and
it does actually use the regular object lookup.
