eb32d236 introduced the OBJ_OFS_DELTA object that uses a relative offset to

fdae191003 doc/http-backend: clarify "half-auth" repo configuration
When the http-backend is set up to allow anonymous read but
authenticated write, the http-backend manual suggests
catching only the "/git-receive-pack" POST of the packfile,
not the initial "info/refs?service=git-receive-pack" GET in
which we advertise refs.

This does work and is secure, as we do not allow any write
during the info/refs request, and the information in the ref
advertisement is the same that you would get from a fetch.

However, the configuration required by the server is
slightly more complex. The default `http.receivepack`
setting is to allow pushes if the webserver tells us that
the user authenticated, and otherwise to return a 403
("Forbidden"). That works fine if authentication is turned
on completely; the initial request requires authentication,
and http-backend realizes it is OK to do a push.

But for this "half-auth" state, no authentication has
occurred during the initial ref advertisement. The
http-backend CGI therefore does not think that pushing
should be enabled, and responds with a 403. The client
cannot continue, even though the server would have allowed
it to run if it had provided credentials.

It would be much better if the server responded with a 401,
asking for credentials during the initial contact. But
git-http-backend does not know about the server's auth
configuration (so a 401 would be confusing in the case of a
true anonymous server). Unfortunately, configuring Apache to
recognize the query string and apply the auth appropriately
to receive-pack (but not upload-pack) initial requests is
non-trivial.

The site admin can work around this by just turning on
http.receivepack explicitly in its repositories. Let's
document this workaround.

5446e33f35 bundle: Accept prerequisites without commit messages
While explicitly stating that the commit message in a prerequisite
line is optional, we required all lines with 40 or more characters
to contain a space after the object name, bailing out if a line
consisted of an object name only. This was to allow bundling a
history to a commit without an message, but the code forgot that it
already called rtrim() to remove that whitespace.

As a workaround, only check for SP when the line has more than 40
characters.

aaa07e3eee show-branch: use strbuf instead of static buffer
When we generate relative names (e.g., "master~20^2"), we
format the name into a static buffer, then xstrdup the
result to attach it to the commit. Since the first thing we
add into the static buffer is the already-computed name of
the child commit, the names may get longer and longer as
the traversal gets deeper, and we may eventually overflow
the fixed-size buffer.

Fix this by converting the fixed-size buffer into a dynamic
strbuf.  The performance implications should be minimal, as
we end up allocating a heap copy of the name anyway (and now
we can just detach the heap copy from the strbuf).

1d77d249f9 glossary: extend "detached HEAD" description
When we introduced the concept of "detached HEAD", we made sure that
commands that operate on the history of the current branch "just
work" in that state.  They update the HEAD to point at the new
history without affecting any branch when the HEAD is detached, just
like they update the tip of the "current branch" to point at the new
history when HEAD points at a specific branch.

As this is done as the natural extension for these commands, we did
not, we still do not, and we do not want to repeat "A detached HEAD
is updated without affecting any branch" when describing what each
and every one of these commands that operates "on the current branch"
does.

Add a blanket description to the glossary to cover them instead.
The general principle is that operations to update the branch work
on and affect the HEAD, while operations to update the information
about a branch do not.

61690bf4a1 diffcore-pickaxe: unify code for log -S/-G
The logic flow of has_changes() used for "log -S" and diff_grep()
used for "log -G" are essentially the same.  See if we have both
sides that could be different in any interesting way, slurp the
contents in core, possibly after applying textconv, inspect the
contents, clean-up and report the result.  The only difference
between the two is how "inspect" step works.

Unify this codeflow in a helper, pickaxe_match(), which takes a
callback function that implements the specific "inspect" step.

After removing the common scaffolding code from the existing
has_changes() and diff_grep(), they each becomes such a callback
function suitable for passing to pickaxe_match().

The diff_grep() and has_changes() functions had early return
codepaths for unmerged filepairs, which simply returned 0.  When we
taught textconv filter to them, one was ignored and continued to
return early without freeing the result filtered by textconv, and
the other had a failed attempt to fix, which allowed the planned
return value 0 to be overwritten by a bogus call to contains().

These two functions are called in the same codeflow to implement

lacked two obvious optimizations the former implemented, namely:

 - When a pickaxe limit is not given at all, they should return
   without wasting any cycle;

 - When both sides of the filepair are the same, and the same
   textconv conversion apply to them, return early, as there will be
   no interesting differences between the two anyway.

not about leaking memory--it is about releasing data we finished

exception is that for the !DIFF_FILE_VALID case, fill_textconv gives us

bc6158981b diffcore-pickaxe: remove unnecessary call to get_textconv()
The fill_one() function is responsible for finding and filling the
textconv filter as necessary, and is called by diff_grep() function
that implements "git log -G<pattern>".

The has_changes() function that implements "git log -S<block>" calls
get_textconv() for two sides being compared, before it checks to see
if it was asked to perform the pickaxe limiting.  Move the code
around to avoid this wastage.

After has_changes() calls get_textconv() to obtain textconv for both
sides, fill_one() is called to use them.

By adding get_textconv() to diff_grep() and relieving fill_one() of
responsibility to find the textconv filter, we can avoid calling
get_textconv() twice in has_changes().

With this change it's also no longer necessary for fill_one() to
modify the textconv argument, therefore pass a pointer instead of a
pointer to a pointer.

The actual complaint appears to be a bug in the underlying
implementation.  What's interesting here is that it is apparently
_triggered_ by closing stderr, which results in (from strace)

  write(2, "fatal: Needed a single revision\n", 32) = -1 EBADF (Bad file descriptor)
  write(2, "\0", 1) = -1 EBADF (Bad file descriptor)

Closing stderr is a bad idea anyway: there is a very real chance that
we print fatal error messages to some other file that just happens to
be opened on the now-free FD 2.  So let's not do that.

As pointed out by Eric Wong (thanks), the initial close needs to go:
die() would again write nowhere if we close STDERR beforehand.

b9e31f5947 rerere forget: do not segfault if not all stages are present
The loop that fills in the buffers that are later passed to the merge
driver exits early when not all stages of a path are present in the index.
But since the buffer pointers are not initialized in advance, the
subsequent accesses are undefined.

Initialize buffer pointers in advance to avoid undefined behavior later.

That is not sufficient, though, to get correct operation of handle_cache().
The function replays a conflicted merge to extract the part inside the
conflict markers. As written, the loop exits early when a stage is missing.
Consequently, the buffers for later stages that would be present in the
index are not filled in and the merge is replayed with incomplete data.

Fix it by investigating all stages of the given path.

e7b00c5764 diffcore-break: don't divide by zero
When the source file is empty, the calculation of the merge score
results in a division by zero.  In the situation:

     == preimage ==             == postimage ==

     F (empty file)             F (a large file)
                                E (a new empty file)

it does not make sense to consider F->E as a rename, so it is better not
to break the pre- and post-image of F.

Bail out early in this case to avoid hitting the divide-by-zero.  This
causes the merge score to be left at zero.
