Improve look of commit search output ('search' view) by better cutting
of matched string and its context in match info, as suggested by Junio.
For example, if you are looking for "very long search string" in the
following line:
Could somebody test this with very long search string, and see how
you would now see:
...this with <<very long ... string>>, and see...
instead of:
Could som... <<very long search...>>, and see...
(where <<something>> denotes emphasized / colored fragment; matched
fragment to be more exact).
For this feature, support for fourth [optional] parameter to chop_str
subroutine was added. This fourth parameter is used to denote where
to cut string to make it shorter. chop_str can now cut at the
beginning (from the _left_ side of the string), in the middle
(_center_ of the string), or at the end (from the _right_ side of
the string); cutting from right is the default:
chop_str(somestring, len, slop, 'left') -> ' ...string'
chop_str(somestring, len, slop, 'center') -> 'som ... ing'
chop_str(somestring, len, slop, 'right') -> 'somestr... '
If you want to use default slop (default additional length), use undef
as value for third parameter to chop_str.
While at it, return from chop_str early if given string is so short
that chop_str couldn't shorten it. Simplify also regexp used by
chop_str. Make ellipsis (dots) stick to shortened fragment for
cutting at ends, to better see which part got shortened.
Simplify passing all arguments to chop_str in chop_and_escape_str
subroutine. This was needed to pass additional options to chop_str.

Git has difficulties on file systems that do not properly
distinguish case or modify filenames in unexpected ways. The two
major examples are Windows and Mac OS X. Both systems preserve
case of file names but do not distinguish between filenames that
differ only by case. Simple operations such as "git mv" or
"git merge" can fail unexpectedly. In addition, Mac OS X normalizes
unicode, which make git's life even harder.
This commit adds tests that currently fail but should pass if
file system as decribed above are fully supported. The test need
to be run on Windows and Mac X as they already pass on Linux.
Mitch Tishmack is the original author of the tests for unicode
normalization.

Most of the time when I am on a detached HEAD and I am not doing
a rebase or bisect operation the working directory is sitting on a
tagged release of the repository. Showing the tag name instead of
the commit SHA-1 is much more descriptive and a much better reminder
of the state of this working directory.
Now that git-describe --exact-match is available as a cheap means
of obtaining the exact annotated tag or nothing at all, we can
favor the annotated tag name over the abbreviated commit SHA-1.

Sometimes scripts want (or need) the annotated tag name that exactly
matches a specific commit, or no tag at all. In such cases it can be
difficult to determine if the output of `git describe $commit` is a
real tag name or a tag+abbreviated commit. A common idiom is to run
git-describe twice:
if test $(git describe $commit) = $(git describe --abbrev=0 $commit)
...
but this is a huge waste of time if the caller is just going to pick a
different method to describe $commit or abort because it is not exactly
an annotated tag.
Setting the maximum number of candidates to 0 allows the caller to ask
for only a tag that directly points at the supplied commit, or to have
git-describe abort if no such item exists.

If we aren't going to use a ref there is no reason for us to open

By using the peeled ref information inside of the packed-refs file we
can avoid opening tag objects to obtain the commits they reference.
This speeds up git-describe when there are a large number of tags

start commit matching.

Currently the only caller of peel_ref is show-ref, which is using
this function to show the peeled tag information if it is available
from an existing packed-refs file. The call happens during the
for_each_ref callback function, so we have the proper struct ref_list
already on the call stack but it is not easily available to return
the peeled information to the caller.
We now save the current struct ref_list item before calling back
into the callback function so that future calls to peel_ref from
within the callback function can quickly access the current ref.
Doing so will save us an lstat() per ref processed as we no longer
have to check the filesystem to see if the ref exists as a loose
file or is packed. This current ref caching also saves a linear
scan of the cached packed refs list.
As a micro-optimization we test the address of the passed ref name
against the current_ref->name before we go into the much more costly
strcmp(). Nearly any caller of peel_ref will be passing us the same
string do_for_each_ref passed them, which is current_ref->name.

So I find it irritating when git thinks for a long time without telling me
what's taking so long. And by "long time" I definitely mean less than two
seconds, which is already way too long for me.
This hits me when doing a large pull and the checkout takes a long time,
or when just switching to another branch that is old and again checkout
takes a while.
Now, git read-tree already had support for the "-v" flag that does nice
updates about what's going on, but it was delayed by two seconds, and if
the thing had already done more than half by then it would be quiet even
after that, so in practice it meant that we migth be quiet for up to four
seconds. Much too long.
So this patch changes the timeout to just one second, which makes it much
more palatable to me.
The other thing this patch does is that "git checkout" now doesn't disable
the "-v" flag when doing its thing, and only disables the output when
given the -q flag. When allowing "checkout -m" to fall back to a 3-way
merge, the users will see the error message from straight "checkout",
so we will tell them that we do fall back to make them look less scary.

We used to just memcpy() the index entry when we copied the stat() and
SHA1 hash information, which worked well enough back when the index
entry was just an exact bit-for-bit representation of the information on
disk.
However, these days we actually have various management information in
the cache entry too, and we should be careful to not overwrite it when
we copy the stat information from another index entry.

This makes the name hash removal function (which really just sets the
bit that disables lookups of it) available to external routines, and
makes read_cache_unmerged() use it when it drops an unmerged entry from

argument.

We handled the case of removing and re-inserting cache entries badly,
which is something that merging commonly needs to do (removing the
different stages, and then re-inserting one of them as the merged
state).
We even had a rather ugly special case for this failure case, where
replace_index_entry() basically turned itself into a no-op if the new
and the old entries were the same, exactly because the hash routines
didn't handle it on their own.
So what this patch does is to not just have the UNHASHED bit, but a
HASHED bit too, and when you insert an entry into the name hash, that
involves:
- clear the UNHASHED bit, because now it's valid again for lookup
(which is really all that UNHASHED meant)
- if we're being lazy, we're done here (but we still want to clear the
UNHASHED bit regardless of lazy mode, since we can become unlazy
later, and so we need the UNHASHED bit to always be set correctly,
even if we never actually insert the entry into the hash list)
- if it was already hashed, we just leave it on the list
- otherwise mark it HASHED and insert it into the list
this all means that unhashing and rehashing a name all just works
automatically. Obviously, you cannot change the name of an entry (that
would be a serious bug), but nothing can validly do that anyway (you'd
have to allocate a new struct cache_entry anyway since the name length
could change), so that's not a new limitation.
The code actually gets simpler in many ways, although the lazy hashing
does mean that there are a few odd cases (ie something can be marked
unhashed even though it was never on the hash in the first place, and
isn't actually marked hashed!).

We were returning the _address of_ the stored item (or NULL)
instead of the item itself. While this sort of indirection
is useful for insertion (since you can lookup and then
modify), it is unnecessary for read-only lookup. Since the
hash code splits these functions between the internal
lookup_hash_entry function and the public lookup_hash
function, it makes sense for the latter to provide what
users of the library expect.
The result of this was that the index caching returned bogus
results on lookup. We unfortunately didn't catch this
because we were returning a "struct cache_entry **" as a
"void *", and accidentally assigning it to a "struct
cache_entry *".
As it happens, this actually _worked_ most of the time,
because the entries were defined as:
struct cache_entry {
struct cache_entry *next;
...
};
meaning that interpreting a "struct cache_entry **" as a
"struct cache_entry *" would yield an entry where all fields
were totally bogus _except_ for the next pointer, which
pointed to the actual cache entry. When walking the list, we
would look at the bogus "name" field, which was unlikely to
match our lookup, and then proceed to the "real" entry.
The reading of bogus data was silently ignored most of the
time, but could cause a segfault for some data (which seems
to be more common on OS X).

When we are being built by the Cygwin package maintainers we need to
embed the POSIX path to our library files and not the Windows path.
Embedding the Windows path means all end-users who install our Cygwin
package would be required to install Cygwin at the same Windows path
as the package maintainer had Cygwin installed to. This requirement
is simply not user-friendly and may be infeasible for a large number
of our users.
We now try to auto-detect if the Tcl/Tk binary we will use at runtime
is capable of translating POSIX paths into Windows paths the same way
that cygpath does the translations. If the Tcl/Tk binary gives us the
same results then it understands the Cygwin path translation process
and should be able to read our library files from a POSIX path name.
If it does not give us the same answer as cygpath then the Tcl/Tk
binary might actually be a native Win32 build (one that is not
linked against Cygwin) and thus requires the native Windows path
to our library files. We can assume this is not a Cygwin package
as the Cygwin maintainers do not currently ship a pure Win32 build
of Tcl/Tk.

Most users set TCLTK_PATH to tell git-gui where to find wish, but they
fail to set TCL_PATH to the same Tcl installation. We use the non-GUI
tclsh during builds so headless systems are still able to create an
index file and create message files without GNU msgfmt. So it matters
to us that we find a working TCL_PATH at build time.
If TCL_PATH hasn't been set yet we can take a better guess about what
tclsh executable to use by replacing 'wish' in the executable path with
'tclsh'. We only do this replacement on the filename part of the path,
just in case the string "wish" appears in the directory paths. Most of
the time the tclsh will be installed alongside wish so this replacement
is a sensible and safe default.
