Under --whitespace=fix option, match_fragment() function examines
the preimage (the common context and the removed lines in the patch)
and the file being patched and checks if they match after correcting
all whitespace errors. When they are found to match, the common
context lines in the preimage is replaced with the fixed copy,
because these lines will then be copied to the corresponding place
in the postimage by a later call to update_pre_post_images(). Lines
that are added in the postimage, under --whitespace=fix, have their
whitespace errors already fixed when apply_one_fragment() prepares
the preimage and the postimage, so in the end, application of the
patch can be done by replacing the block of text in the file being
patched that matched the preimage with what is in the postimage that
was updated by update_pre_post_images().
In the earlier days, fixing whitespace errors always resulted in
reduction of size, either collapsing runs of spaces in the indent to
a tab or removing the trailing whitespaces. These days, however,
some whitespace error fix results in extending the size.
250b3c6c (apply --whitespace=fix: avoid running over the postimage
buffer, 2013-03-22) tried to compute the final postimage size but
its math was flawed. It counted the size of the block of text in
the original being patched after fixing the whitespace errors on its
lines that correspond to the preimage. That number does not have
much to do with how big the final postimage would be.
Instead count (1) the added lines in the postimage, whose size is
the same as in the final patch result because their whitespace
errors have already been corrected, and (2) the fixed size of the
lines that are common.
apply: make update_pre_post_images() sanity check the given postlen
"git apply --whitespace=fix" used to be able to assume that fixing
errors will always reduce the size by e.g. stripping whitespaces at
the end of lines or collapsing runs of spaces into tabs at the
beginning of lines. An update to accomodate fixes that lengthens
the result by e.g. expanding leading tabs into spaces were made long
time ago but the logic miscounted the necessary space after such
whitespace fixes, leading to either under-allocation or over-usage
of already allocated space.
Illustrate this with a runtime sanity-check to protect us from
future breakage. The test was stolen from Kyle McKay who helped
to identify the problem.

rebase -i: use full object name internally throughout the script
In earlier days, the abbreviated commit object name shown to the end
users were generated with hardcoded --abbrev=7; 56895038 (rebase
-i: respect core.abbrev, 2013-09-28) tried to make it honor the user
specified core.abbrev, but it missed the very initial invocation of
the editor.
These days, we try to use the full 40-hex object names internally to
avoid ambiguity that can arise after rebase starts running. Newly
created objects during the rebase may share the same prefix with
existing commits listed in the insn sheet. These object names are
shortened just before invoking the sequence editor to present the
insn sheet to the end user, and then expanded back to full object
names when the editor returns.
But the code still used the shortened names when preparing the insn
sheet for the very first time, resulting "7 hexdigits or more"
output to the user. Change the code to use full 40-hex commit
object names from the very beginning to make things more uniform.

transport-helper: do not request symbolic refs to remote helpers
A typical remote helper will return a `list` of refs containing a symbolic
ref HEAD, pointing to, e.g. refs/heads/master. In the case of a clone, all
the refs are being requested through `fetch` or `import`, including the
symbolic ref.
While this works properly, in some cases of a fetch, like `git fetch url`
or `git fetch origin HEAD`, or any fetch command involving a symbolic ref
without also fetching the corresponding ref it points to, the fetch command
fails with:
(in the case the remote helper returned '?' values to the `list` command).
This is because there is only one ref given to fetch(), and it's not
further resolved to something at the end of fetch_with_import().
While this can be somehow handled in the remote helper itself, by adding
a refspec for the symbolic ref, and storing an explicit ref in a private
namespace, and then handling the `import` for that symbolic ref
specifically, very few existing remote helpers are actually doing that.
So, instead of requesting the exact list of wanted refs to remote helpers,
treat symbolic refs differently and request the ref they point to instead.
Then, resolve the symbolic refs values based on the pointed ref.
This assumes there is no more than one level of indirection (a symbolic
ref doesn't point to another symbolic ref).

POSIXPERM requires that a later call to stat(2) (hence "ls -l")
faithfully reproduces what an earlier chmod(2) did. Some
filesystems cannot satisify this.
SANITY requires that a file or a directory is indeed accessible (or
inaccessible) when its permission bits would say it ought to be
accessible (or inaccessible). Running tests as root would lose this
prerequisite for obvious reasons.
Fix a few tests that misuse POSIXPERM.
t0061-run-command.sh has two uses of POSIXPERM.
- One checks that an attempt to execute a file that is marked as
unexecutable results in a failure with EACCES; I do not think
having root-ness or any other capability that busts the
filesystem permission mode bits will make you run an unexecutable
file, so this should be left as-is. The test does not have
anything to do with SANITY.
- The other one expects 'git nitfol' runs the alias when an
alias.nitfol is defined and a directory on the PATH is marked as
unreadable and unsearchable. I _think_ the test tries to reject
the alternative expectation that we want to refuse to run the
alias because it would break "no alias may mask a command" rule
if a file 'git-nitfol' exists in the unreadable directory but we
cannot even determine if that is the case. Under !SANITY that
busts the permission bits, this test no longer checks that, so it
must be protected with SANITY.
t1509-root-worktree.sh expects to be run on a / that is writable by
the user and sees if Git behaves "sensibly" when /.git is the
repository to govern a worktree that is the whole filesystem, and
also if Git behaves "sensibly" when / itself is a bare repository
with refs, objects, and friends (I find the definition of "behaves
sensibly" under these conditions hard to fathom, but it is a
different matter).
The implementation of the test is very much problematic.
- It requires POSIXPERM, but it does not do chmod or checks modes
in any way.
- It runs "rm /*" and "rm -fr /refs /objects ..." in one of the
tests, and also does "cd / && git init --bare". If done on a
live system that takes advantages of the "feature" being tested,
these obviously will clobber the system. But there is no guard
against such a breakage.
- It uses "test $UID = 0" to see rootness, which now should be
spelled "! test_have_prereq NOT_ROOT"
The SANITY prerequisite is really about whether the
filesystem will respect the permissions we set, and being
root is only one part of that. But the httpd tests really
just care about not being root, as they are trying to avoid
weirdness in apache (see a1a3011 for details).
Let's switch out SANITY for a new NOT_ROOT prerequisite,
which will let us tweak SANITY more freely.
We implement NOT_ROOT by checking `id -u`, which is in POSIX
and seems to be available even on MSYS. Note that we cannot
just call this "ROOT" and ask for "!ROOT". The possible
outcomes are:
1. we know we are root
2. we know we are not root
3. we could not tell, because `id` was not available
We should conservatively treat (3) as "does not have the
prerequisite", which means that a naive negation would not
work.

For some unknown reason, the dd on my Windows box segfaults randomly,
but since recently, it does so much more often than it used to, which
makes running the test suite burdensome.
Use printf to write large files instead of dd. To emphasize that three
of the large blobs are exact copies, use cp to allocate them.
The new code makes the files a bit smaller, and they are not sparse
anymore, but the tests do not depend on these properties. We do not want
to use test-genrandom here (which is used to generate large files
elsewhere in t1050), so that the files can be compressed well (which
keeps the run-time short).
The files are now large text files, not binary files. But since they
are larger than core.bigfilethreshold they are diagnosed as binary
by Git. For this reason, the 'git diff' tests that check the output
for "Binary files differ" still pass.

http-push: trim trailing newline from remote symref
When we fetch a symbolic ref file from the remote, we get
the whole string "ref: refs/heads/master\n", recognize it by
skipping past the "ref: ", and store the rest. We should
chomp the trailing newline.
This bug was introduced in ae021d8 (use skip_prefix to avoid
magic numbers, 2014-06-18), which did not notice that the
length computation fed to xmemdupz was quietly tweaked by 1
to account for this.
We can solve it by explicitly trimming the newline, which is
more obvious. Note that we use strbuf_rtrim here, which will
actually cut off any trailing whitespace, not just a single
newline. This is a good thing, though, as it makes our
parsing more liberal (and spaces are not valid in refnames
anyway).

It's a common idiom to duplicate a string if it is non-NULL,
or pass a literal NULL through. This is already a one-liner
in C, but you do have to repeat the name of the string
twice. So if there's a function call, you must write:
doc: core.ignoreStat update, and clarify the --assume-unchanged effect
The assume-unchanged bit, and consequently core.ignoreStat, can be
misunderstood. Be assertive about the expectation that file changes should
notified to Git.
Overhaul the general wording thus:
1. direct description of what is ignored given first.
2. example instruction of the user manual action required.
3. use sideways indirection for assume-unchanged and update-index
references.
4. add a 'normally' to give leeway for the change detection.

for-each-ref: always check stat_tracking_info()'s return value
The code handling %(upstream:track) and %(upstream:trackshort)
assumed that it always had a valid branch that had been sanitized
earlier in populate_value(), and thus did not check the return value
of the call to stat_tracking_info().
While there is indeed some sanitization code that basically
corresponds to stat_tracking_info() returning 0 (no base branch
set), the function can also return -1 when the base branch did exist
but has since then been deleted.
In this case, num_ours and num_theirs had undefined values and a
call to `git for-each-ref --format="%(upstream:track)"` could print
spurious values such as
Verify stat_tracking_info()'s return value and do not print anything

- "exec_cmd.h" became unnecessary at b931aa5a (Call builtin ls-tree

that delegated tree display to "ls-tree" via the run_command()
API (hence needing "exec_cmd.h") to call cmd_ls_tree() directly.
We should have removed the include in the same commit, but we

the type of object by comparing typename with tree_type and
tag_type (pointers to extern strings).
21666f1a (convert object type handling from a string to a number,

could have switched to include "object.h", which is necessary to
use typename(), but it forgot to do so. Because "tag.h" and
"tree.h" include "object.h", it did not need to explicitly
include "object.h" in order to start using typename() itself.
We do not even have to include "object.h" after removing these
two #includes, because "builtin.h" includes "commit.h" which in

remote-curl: fall back to Basic auth if Negotiate fails
Apache servers using mod_auth_kerb can be configured to allow the user
to authenticate either using Negotiate (using the Kerberos ticket) or
Basic authentication (using the Kerberos password). Often, one will
want to use Negotiate authentication if it is available, but fall back
to Basic authentication if the ticket is missing or expired.
However, libcurl will try very hard to use something other than Basic
auth, even over HTTPS. If Basic and something else are offered, libcurl
will never attempt to use Basic, even if the other option fails.
Teach the HTTP client code to stop trying authentication mechanisms that
don't use a password (currently Negotiate) after the first failure,
since if they failed the first time, they will never succeed.
