dirty working tree.

This patch adds a call to "update-index --refresh". It comes

having resolved conflicts), and not once per patch.

ls-files: fix pathspec display on error

The following sequence of commands reveals an issue with error
reporting of relative paths:

 $ mkdir sub
 $ cd sub
 $ git ls-files --error-unmatch ../bbbbb
 error: pathspec 'b' did not match any file(s) known to git.
 $ git commit --error-unmatch ../bbbbb
 error: pathspec 'b' did not match any file(s) known to git.

This bug is visible only if the normalized path (i.e., the relative
path from the repository root) is longer than the prefix.
Otherwise, the code skips over the normalized path and reads from
an unused memory location which still contains a leftover of the
original command line argument.

So instead, use the existing facilities to deal with relative paths
correctly.

Also fix inconsistency between "checkout" and "commit", e.g.

    $ cd Documentation
    $ git checkout nosuch.txt
    error: pathspec 'Documentation/nosuch.txt' did not match...
    $ git commit nosuch.txt
    error: pathspec 'nosuch.txt' did not match...

by propagating the prefix down the codepath that reports the error.

Roberto Tyley [Sun, 7 Aug 2011 18:46:13 +0000 (19:46 +0100)] 
Tolerate zlib deflation with window size < 32Kb

Git currently reports loose objects as 'corrupt' if they've been
deflated using a window size less than 32Kb, because the
experimental_loose_object() function doesn't recognise the header
byte as a zlib header. This patch makes the function tolerant of
all valid window sizes (15-bit to 8-bit) - but doesn't sacrifice
it's accuracy in distingushing the standard loose-object format
from the experimental (now abandoned) format.

On memory constrained systems zlib may use a much smaller window
size - working on Agit, I found that Android uses a 4KB window;
giving a header byte of 0x48, not 0x78. Consequently all loose
objects generated appear 'corrupt', which is why Agit is a read-only
Git client at this time - I don't want my client to generate Git
repos that other clients treat as broken :(

This patch makes Git tolerant of different deflate settings - it
might appear that it changes experimental_loose_object() to the point
where it could incorrectly identify the experimental format as the
standard one, but the two criteria (bitmask & checksum) can only
give a false result for an experimental object where both of the
following are true:

1) object size is exactly 8 bytes when uncompressed (bitmask)
2) [single-byte in-pack git type&size header] * 256
   + [1st byte of the following zlib header] % 31 = 0 (checksum)

As it happens, for all possible combinations of valid object type
(1-4) and window bits (0-7), the only time when the checksum will be
divisible by 31 is for 0x1838 - ie object type *1*, a Commit - which,
due the fields all Commit objects must contain, could never be as
small as 8 bytes in size.

Given this, the combination of the two criteria (bitmask & checksum)
always correctly determines the buffer format, and is more tolerant
than the previous version.

The alternative to this patch is simply removing support for the
experimental format, which I am also totally cool with.

When the server tries to respond to this second request, its refs may have
progressed by a push from elsewhere. By design, we do not allow fetching
objects that are not at the tip of an advertised ref, and the server

In olden times, tests would quietly exit the script when they failed

Therefore v0.99.5~24^2~4 (Trapping exit in tests, using return for
errors, 2005-08-10) switched to an idiom of using "return" instead,
wrapping evaluation of test code in a function to make that safe:

test_run_ () {
eval >&3 2>&4 "$1"
eval_ret="$?"
return 0
}

Years later, the implementation of test_when_finished (v1.7.1.1~95,
2010-05-02) and v1.7.2-rc2~1^2~13 (test-lib: output a newline before
"ok" under a TAP harness, 2010-06-24) took advantage of test_run_ as a
place to put code shared by all test assertion functions, without
paying attention to the function's former purpose:

test_run_ () {
...
eval >&3 2>&4 "$1"
eval_ret=$?

if should run cleanup
then
eval >&3 2>&4 "$test_cleanup"
fi
if TAP format requires a newline here
then
echo
fi
return 0
}

That means cleanup commands and the newline to put TAP output at
column 0 are skipped when tests use "return" to fail early.  Fix it by
introducing a test_eval_ function to catch the "return", with a
comment explaining the new function's purpose for the next person who

12 years agofast-export: quote paths in output
Jeff King [Fri, 5 Aug 2011 22:36:22 +0000 (16:36 -0600)] 
fast-export: quote paths in output

Many pathnames in a fast-import stream need to be quoted. In
particular:

  1. Pathnames at the end of an "M" or "D" line need quoting
     if they contain a LF or start with double-quote.

  2. Pathnames on a "C" or "R" line need quoting as above,
     but also if they contain spaces.

For (1), we weren't quoting at all. For (2), we put
double-quotes around the paths to handle spaces, but ignored
the possibility that they would need further quoting.

This patch checks whether each pathname needs c-style
quoting, and uses it. This is slightly overkill for (1),
which doesn't actually need to quote many characters that
vanilla c-style quoting does. However, it shouldn't hurt, as
any implementation needs to be ready to handle quoted
strings anyway.

In addition to adding a test, we have to tweak a test which
blindly assumed that case (2) would always use
double-quotes, whether it needed to or not.

git-check-attr: Normalize paths

Normalize the path arguments (relative to the working tree root, if
applicable) before looking up their attributes.  This requires passing
the prefix down the call chain.

This fixes two test cases for different reasons:

* "unnormalized paths" is fixed because the .gitattribute-file-seeking
  code is not confused into reading the top-level file twice.

* "relative paths" is fixed because the canonical pathnames are passed
  to get_check_attr() or get_all_attrs(), allowing them to match the
  pathname patterns as expected.
