On a multiuser system where mortals do not have write access to /etc,
the GIT_CONFIG_NOSYSTEM variable is the best tool we have to keep
getting work done when a syntax error or other problem renders
/etc/gitconfig buggy, until the sysadmin sorts the problem out.
Noticed while experimenting with teaching git to error out when
/etc/gitconfig is unreadable.

Git reads multiple configuration files: settings come first from the
system config file (typically /etc/gitconfig), then the xdg config
file (typically ~/.config/git/config), then the user's dotfile
(~/.gitconfig), then the repository configuration (.git/config).
Git has always used access(2) to decide whether to use each file; as
an unfortunate side effect, that means that if one of these files is
unreadable (e.g., EPERM or EIO), git skips it. So if I use
~/.gitconfig to override some settings but make a mistake and give it
the wrong permissions then I am subject to the settings the sysadmin
chose for /etc/gitconfig.
Better to error out and ask the user to correct the problem.
This only affects the user and xdg config files, since the user
presumably has enough access to fix their permissions. If the system
config file is unreadable, the best we can do is to warn about it so
the user knows to notify someone and get on with work in the meantime.

The access_or_warn() function is used to check for optional
configuration files like .gitconfig and .gitignore and warn when they
are not accessible due to a configuration issue (e.g., bad
permissions). It is not supposed to complain when a file is simply
missing.
Noticed on a system where ~/.config/git was a file --- when the new
XDG_CONFIG_HOME support looks for ~/.config/git/config it should
ignore ~/.config/git instead of printing irritating warnings:
$ git status -s
warning: unable to access '/home/jrn/.config/git/config': Not a directory
warning: unable to access '/home/jrn/.config/git/config': Not a directory
warning: unable to access '/home/jrn/.config/git/config': Not a directory

5166714 (apply: Allow blank context lines to match beyond EOF,
2010-03-06) and then later 0c3ef98 (apply: Allow blank *trailing*
context lines to match beyond EOF, 2010-04-08) taught "git apply"
to trim new blank lines at the end in the patch text when matching
the contents being patched and the preimage recorded in the patch,
under --whitespace=fix mode.
When a preimage is modified to match the current contents in
preparation for such a "fixed" patch application, the context lines
in the postimage must be updated to match (otherwise, it would
reintroduce whitespace breakages), and update_pre_post_images()
function is responsible for doing this. However, this function was
not updated to take into account a case where the removal of
trailing blank lines reduces the number of lines in the preimage,
and triggered an assertion error.
The logic to fix the postimage by copying the corrected context
lines from the preimage was not prepared to handle this case,
either, but it was protected by the assert() and only got exposed
when the assertion is corrected.

When we get an http 401, we prompt for credentials and put
them in our global credential struct. We also feed them to
the curl handle that produced the 401, with the intent that
they will be used on a retry.
When the code was originally introduced in commit 42653c0,
this was a necessary step. However, since dfa1725, we always
feed our global credential into every curl handle when we
initialize the slot with get_active_slot. So every further
request already feeds the credential to curl.
Moreover, accessing the slot here is somewhat dubious. After
the slot has produced a response, we don't actually control
it any more. If we are using curl_multi, it may even have
been re-initialized to handle a different request.
It just so happens that we will reuse the curl handle within
the slot in such a case, and that because we only keep one
global credential, it will be the one we want. So the
current code is not buggy, but it is misleading.
By cleaning it up, we can remove the slot argument entirely
from handle_curl_result, making it much more obvious that
slots should not be accessed after they are marked as
finished.

Commit b81401c (http: prompt for credentials on failed POST)
taught post_rpc to call run_slot in a loop in order to retry
a request after asking the user for credentials. However,
after a call to run_slot we will have called
finish_active_slot. This means we have released the slot,
and we should no longer look at it.
As it happens, this does not cause any bugs in the current
code, since we know that we are not using curl_multi in this
code path, and therefore nobody will have taken over our
slot in the meantime. However, it is good form to actually
call get_active_slot again. It also future proofs us against
changes in the http code.
We can do this by jumping back to a retry label at the top
of our function. We just need to reorder a few setup lines
that should not be repeated; everything else within the loop
is either idempotent, needs to be repeated, or in a path we
do not follow (e.g., we do not even try when large_request
is set, because we don't know how much data we might have
streamed from our helper program).

When we create an http active_request_slot, we can set its
"results" pointer back to local storage. The http code will
fill in the details of how the request went, and we can
access those details even after the slot has been cleaned
up.
Commit 8809703 (http: factor out http error code handling)
switched us from accessing our local results struct directly
to accessing it via the "results" pointer of the slot. That
means we're accessing the slot after it has been marked as
finished, defeating the whole purpose of keeping the results
storage separate.
Most of the time this doesn't matter, as finishing the slot
does not actually clean up the pointer. However, when using
curl's multi interface with the dumb-http revision walker,
we might actually start a new request before handing control
back to the original caller. In that case, we may reuse the
slot, zeroing its results pointer, and leading the original
caller to segfault while looking for its results inside the
slot.
Instead, we need to pass a pointer to our local results
storage to the handle_curl_result function, rather than
relying on the pointer in the slot struct. This matches what
the original code did before the refactoring (which did not
use a separate function, and therefore just accessed the
results struct directly).

grep searches for .gitattributes using "name" field in struct
grep_source but that field is not real on-disk path name. For example,
"grep pattern rev" fills the field with "rev:path", and Git looks for
.gitattributes in the (non-existent but exploitable) path "rev:path"
instead of "path".
This patch passes real paths down to grep_source_load_driver() when:
- grep on work tree
- grep on the index
- grep a commit (or a tag if it points to a commit)
so that these cases look up .gitattributes at proper paths.
.gitattributes lookup is disabled in all other cases.

'format-patch' could fail due to reasons such as out of memory. Such
failures are not detected or handled, which causes rebase to incorrectly
think that it completed successfully and continue with cleanup. i.e.
calling move_to_original_branch
Instead of using a pipe, we separate 'format-patch' and 'am' by using an
intermediate file. This gurantees that we can invoke 'am' with the
complete input, or not invoking 'am' at all if 'format-patch' failed.
Also remove the use of '&&' at the end of the if-block, and rearrange

This test script uses "svn cp" to create a branch with an @-sign in
its name:
svn cp "pr ject/trunk" "pr ject/branches/not-a@{0}reflog"
That sets up for later tests that fetch the branch and check that git
svn mangles the refname appropriately.
Unfortunately, modern svn versions interpret path arguments with an
@-sign as an example of path@revision syntax (which pegs a path to a
particular revision) and truncate the path or error out with message
"svn: E205000: Syntax error parsing peg revision '{0}reflog'".
When using subversion 1.6.x, escaping the @ sign as %40 avoids trouble
(see 08fd28bb, 2010-07-08). Newer versions are stricter:
$ svn cp "$repo/pr ject/trunk" "$repo/pr ject/branches/not-a%40{reflog}"
svn: E205000: Syntax error parsing peg revision '%7B0%7Dreflog'
The recommended method for escaping a literal @ sign in a path passed
to subversion is to add an empty peg revision at the end of the path
("branches/not-a@{0}reflog@"). Do that.
Pre-1.6.12 versions of Subversion probably treat the trailing @ as
another literal @-sign (svn issue 3651). Luckily ever since
v1.8.0-rc0~155^2~7 (t9118: workaround inconsistency between SVN
versions, 2012-07-28) the test can survive that.

Subversion represents symlinks as ordinary files with content starting
with "link " and the svn:special property set to "*". Thus a file can
switch between being a symlink and a non-symlink simply by toggling
its svn:special property, and new checkouts will automatically write a
file of the appropriate type. Likewise, in subversion 1.6 and older,
running "svn update" would notice changes in filetype and update the
working copy appropriately.
Starting in subversion 1.7 (issue 4091), changes to the svn:special
property trip an assertion instead:
$ svn up svn-tree
Updating 'svn-tree':
svn: E235000: In file 'subversion/libsvn_wc/update_editor.c' \
line 1583: assertion failed (action == svn_wc_conflict_action_edit \
|| action == svn_wc_conflict_action_delete || action == \
svn_wc_conflict_action_replace)
Revisions prepared with ordinary svn commands ("svn add" and not "svn
propset") don't trip this because they represent these filetype
changes using a replace operation, which is approximately equivalent
to removal followed by adding a new file and works fine. Follow suit.
Noticed using t9100. After this change, git-svn's file-to-symlink
changes are sent in a format that modern "svn update" can handle and
tests t9100.11-13 pass again.

The grep_config() function takes one instance of grep_opt as its
callback parameter, and populates it by running git_config().
This has three practical implications:
- You have to have an instance of grep_opt already when you call
the configuration, but that is not necessarily always true. You
may be trying to initialize the grep_filter member of rev_info,
but are not ready to call init_revisions() on it yet.
- It is not easy to enhance grep_config() in such a way to make it
cascade to other callback functions to grab other variables in
one call of git_config(); grep_config() can be cascaded into from
other callbacks, but it has to be at the leaf level of a cascade.
- If you ever need to use more than one instance of grep_opt, you
will have to open and read the configuration file(s) every time
you initialize them.
Rearrange the configuration mechanism and model it after how diff
configuration variables are handled. An early call to git_config()
reads and remembers the values taken from the configuration in the
default "template", and a separate call to grep_init() uses this
template to instantiate a grep_opt.
The next step will be to move some of this out of this file so that
the other user of the grep machinery (i.e. "log") can use it.
