fast-export can fail because of some pruned-reference when importing a
mark file.
The problem happens in the following scenario:
$ git fast-export --export-marks=MARKS master
(rewrite master)
$ git prune
$ git fast-export --import-marks=MARKS master
This might fail if some references have been removed by prune
because some marks will refer to no longer existing commits.
git-fast-export will not need these objects anyway as they were no
longer reachable.
We still need to update last_numid so we don't change the mapping
between marks and objects for remote-helpers.
Unfortunately, the mark file should not be rewritten without lost marks
if no new objects has been exported, as we could lose track of the last
last_numid.

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).

When we encounter an unknown http error (e.g., a 403), we
hand the error code to http_error, which then prints it with
error(). After that we die with the redundant message "HTTP
request failed".
Instead, let's just drop http_error entirely, which does
nothing but pass arguments to error(), and instead die
directly with a useful message.
So before:
$ git clone https://example.com/repo.git
Cloning into 'repo'...
error: unable to access 'https://example.com/repo.git': The requested URL returned error: 403 Forbidden
fatal: HTTP request failed
and after:
$ git clone https://example.com/repo.git

When we report an http error code, we say something like:
error: The requested URL reported failure: 403 Forbidden while accessing http://example.com/repo.git
Everything between "error:" and "while" is written by curl,
and the resulting sentence is hard to read (especially
because there is no punctuation between curl's sentence and
the remainder of ours). Instead, let's re-order this to give
better flow:
error: unable to access 'http://example.com/repo.git: The requested URL reported failure: 403 Forbidden

clearly left to right.

This helper function should really be a one-liner that
prints an error message, but it has ended up unnecessarily
complicated:
1. We call error() directly when we fail to start the curl
request, so we must later avoid printing a duplicate
error in http_error().
It would be much simpler in this case to just stuff the
error message into our usual curl_errorstr buffer
rather than printing it ourselves. This means that
http_error does not even have to care about curl's exit
value (the interesting part is in the errorstr buffer
already).
2. We return the "ret" value passed in to us, but none of
the callers actually cares about our return value. We
can just drop this entirely.

When we report http errors in fetching the initial ref
advertisement, we show the full URL we attempted to use,
including "info/refs?service=git-upload-pack". While this
may be useful for debugging a broken server, it is
unnecessarily verbose and confusing for most cases, in which
the client user is not even the same person as the owner of
the repository.
Let's just show the repository URL; debugging can happen
with GIT_CURL_VERBOSE, which shows way more useful
information, anyway.
At the same time, let's also make sure to mention the
repository URL when we report failed authentication
(previously we said only "Authentication failed"). Knowing
the URL can help the user realize why authentication failed
(e.g., they meant to push to remote A, not remote B).

When we get an http 404 trying to get the initial list of

$ git clone https://github.com/non/existent
Cloning into 'existent'...
fatal: https://github.com/non/existent/info/refs?service=git-upload-pack not found: did you run git update-server-info on the server?
Suggesting update-server-info may be a good suggestion for
users who are in control of the server repo and who are
planning to set up dumb http. But for users of smart http,
and especially users who are not in control of the server
repo, the advice is useless and confusing.
Since most people are expected to use smart http these days,
it does not make sense to keep the update-server-info hint.
We not only drop the mention of update-server-info, but also
show only the main repo URL, not the full "info/refs" and
service parameter. These elements may be useful for
debugging a broken server configuration, but in the majority
of cases, users are not fetching from their own
repositories, but rather from other people's repositories;
they have neither the power nor interest to fix a broken
configuration, and the extra components just make the
message more confusing. Users who do want to debug can and
should use GIT_CURL_VERBOSE to get more complete information
on the actual URLs visited.

If an http request to a remote git server fails, we show
only the http response code, or sometimes a custom message
for particular codes. This gives the server no opportunity
to offer a more detailed explanation of the reason for the
failure, or to give extra advice.
This patch teaches remote-curl to record and display the
body content of a failed http response. We only display such
responses when the content-type is advertised as text/plain,
as it is the most likely to look presentable on the user's
terminal (and it is hoped to be a good indication that the
message is intended for git clients, and not for a web
browser).
Each line of the new output is prepended with "remote:".
Example output may look like this (assuming the server is
configured to display such a helpful message):
$ GIT_SMART_HTTP=0 git clone https://example.com/some/repo.git
Cloning into 'repo'...
remote: Sorry, fetching via dumb http is forbidden.
remote: Please upgrade your git client to v1.6.6 or greater
remote: and make sure that smart-http is enabled.
error: The requested URL returned error: 403 while accessing http://localhost:5001/some/repo.git/info/refs
fatal: HTTP request failed
For the sake of simplicity, we only record and display these
errors during the initial fetch of the ref list, as that is
the initial contact with the server and where the most
common, interesting errors happen (and there is already
precedent, as that is the only place we currently massage
http error codes into more helpful messages).

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.

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().

These two functions are called in the same codeflow to implement
"log -S<block>" and "log -G<pattern>", respectively, but the latter
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.
Also release the filespec data once the processing is done (this is
not about leaking memory--it is about releasing data we finished

If we have a symlink "d" that points to a directory, we
should not be able to remove "d/f". In the normal case,
where "d/f" does not exist in the index, we already disallow
this, as we only remove things that git knows about in the
index. So for something like:
ln -s /outside/repo foo
git add foo
git rm foo/bar
we will properly produce an error (as there is no index
entry for foo/bar). However, if there is an index entry for
the path (e.g., because the movement is due to working tree
changes that have not yet been reflected in the index), we
will happily delete it, even though the path we delete from the
filesystem is not the same as the path in the index.
This patch documents that failure with a test.
While this is a bug, it should not be possible to cause
serious data loss with it. For any path that does not have
an index entry, we will complain and bail. For a path which
does have an index entry, we will do the usual up-to-date
content check. So even if the deleted path in the filesystem
is not the same as the one we are removing from the index,
we do know that they at least have the same content, and
that the content is included in HEAD.
That means the worst case is not the accidental loss of
content, but rather confusion by the user when a copy of a
file another part of the tree is removed. Which makes this
bug a minor and hard-to-trigger annoyance rather than a
data-loss bug (and hence the fix can be saved for a rainy
day when somebody feels like working on it).

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.

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
