reencode_string(): introduce and use same_encoding()
Callers of reencode_string() that re-encodes a string from one
encoding to another all used ad-hoc way to bypass the case where the
input and the output encodings are the same. Some did strcmp(),
some did strcasecmp(), yet some others when converting to UTF-8 used
is_encoding_utf8().
Introduce same_encoding() helper function to make these callers use
the same logic. Notably, is_encoding_utf8() has a work-around for
common misconfiguration to use "utf8" to name UTF-8 encoding, which
does not match "UTF-8" hence strcasecmp() would not consider the
same. Make use of it in this helper function.
On many platforms, the first invocation of localtime_r will
check $TZ in the environment, but subsequent invocations
will use a cached value. That means that setting $ENV{TZ} in
the middle of the program may or may not have an effect on
later calls to localtime. Perl 5.10.0 and later handles
this automatically for us, but we try to remain portable
back to 5.8. Work around it by calling tzset ourselves.

strbuf_split*(): rename "delim" parameter to "terminator"
The word "delimiter" suggests that the argument separates the
substrings, whereas in fact (1) the delimiter characters are included
in the output, and (2) if the input string ends with the delimiter,
then the output does not include a final empty string. So rename the
"delim" arguments of the strbuf_split() family of functions to
"terminator", which is more suggestive of how it is used.

remote-curl: retry failed requests for auth even with gzip
Commit b81401c taught the post_rpc function to retry the
http request after prompting for credentials. However, it
did not handle two cases:
1. If we have a large request, we do not retry. That's OK,
since we would have sent a probe (with retry) already.
2. If we are gzipping the request, we do not retry. That
was considered OK, because the intended use was for
push (e.g., listing refs is OK, but actually pushing
objects is not), and we never gzip on push.
This patch teaches post_rpc to retry even a gzipped request.
This has two advantages:
1. It is possible to configure a "half-auth" state for
fetching, where the set of refs and their sha1s are
advertised, but one cannot actually fetch objects.
This is not a recommended configuration, as it leaks
some information about what is in the repository (e.g.,
an attacker can try brute-forcing possible content in
your repository and checking whether it matches your
branch sha1). However, it can be slightly more
convenient, since a no-op fetch will not require a
password at all.
2. It future-proofs us should we decide to ever gzip more
requests.
remote-curl: hoist gzip buffer size to top of post_rpc
When we gzip the post data for a smart-http rpc request, we
compute the gzip body and its size inside the "use_gzip"
conditional. We keep track of the body after the conditional
ends, but not the size. Let's remember both, which will
enable us to retry failed gzip requests in a future patch.
This fixes the vast majority of test failures on HP NonStop.

If you remove a submodule, in order to keep the repository so that
"git checkout" to an older commit in the superproject history can
resurrect the submodule, the real repository will stay in $GIT_DIR

different submodule at the same path will fail. Diagnose this case

Now transport-helper correctly detects the errors from fast-import,
unfortunately, not from fast-export because it might finish before
detecting a SIGPIPE. This means transport-helper will quit silently and
the user will not see any errors, which is bad. Hopefully the helper
will print the error before dying anyway, so not all is lost.

When renaming orig_args to orig_flags in 98dbe63d (submodule: only
preserve flags across recursive status/update invocations) the call site
of the recursive cmd_status was forgotten. At that place orig_args is
still passed into the recursion, which is always empty since then. This
did not break anything because the orig_flags logic is not needed at all
when a function from the submodule script is called with eval, as that
inherits all the variables set by the option parsing done in the first
level of the recursion.
Now that we know that orig_flags and orig_args aren't needed at all,

A test in t7404-submodule-foreach purports to test that

to the foreach command as it descends into nested

test since the change it looks for is in a top-level
submodule handled by the first invocation of the command.
To properly test for the flag being passed to recursive
invocations, the change must be buried deeper in the
hierarchy.

parse_dirstat_params(): use string_list to split comma-separated string
Use string_list_split_in_place() to split the comma-separated
parameters string. This simplifies the code and also fixes a bug: the
old code made calls like
memcmp(p, "lines", p_len)
which needn't work if p_len is different than the length of the
constant string (and could illegally access memory if p_len is larger
than the length of the constant string).
When p_len was less than the length of the constant string, the old
code would have allowed some abbreviations to be accepted (e.g., "cha"
for "changes") but this seems to have been a bug rather than a
feature, because (1) it is not documented; (2) no attempt was made to
handle ambiguous abbreviations, like "c" for "changes" vs
"cumulative".

setup_git_directory_gently_1(): resolve symlinks in ceiling paths
longest_ancestor_length() relies on a textual comparison of directory
parts to find the part of path that overlaps with one of the paths in
prefix_list. But this doesn't work if any of the prefixes involves a
symbolic link, because the directories will look different even though
they might logically refer to the same directory. So canonicalize the
paths listed in GIT_CEILING_DIRECTORIES using real_path_if_valid()
before passing them to longest_ancestor_length(). (Also rename
normalize_ceiling_entry() to canonicalize_ceiling_entry() to reflect
the change.)
path is already in canonical form, so doesn't need to be canonicalized
again.
This fixes some problems with using GIT_CEILING_DIRECTORIES that
contains paths involving symlinks, including t4035 if run with --root
set to a path involving symlinks.
Please note that test t0060 is *not* changed analogously, because that
would make the test suite results dependent on the contents of the
local root directory. However, real_path() is already tested
independently, and the "ancestor" tests cover the non-normalization
aspects of longest_ancestor_length(), so coverage remains sufficient.

longest_ancestor_length(): require prefix list entries to be normalized
Move the responsibility for normalizing prefixes from
longest_ancestor_length() to its callers. Use slightly different
normalizations at the two callers:
In setup_git_directory_gently_1(), use the old normalization, which
ignores paths that are not usable. In the next commit we will change
this caller to also resolve symlinks in the paths from
GIT_CEILING_DIRECTORIES as part of the normalization.
In "test-path-utils longest_ancestor_length", use the old
normalization, but die() if any paths are unusable. Also change t0060
to only pass normalized paths to the test program (no empty entries or
non-absolute paths, strip trailing slashes from the paths, and remove
tests that thereby become redundant).
The point of this change is to reduce the scope of the ancestor_length
tests in t0060 from testing normalization+longest_prefix to testing
only mostly longest_prefix. This is necessary because when
setup_git_directory_gently_1() starts resolving symlinks as part of
its normalization, it will not be reasonable to do the same in the
test suite, because that would make the test results depend on the
contents of the root directory of the filesystem on which the test is
run. HOWEVER: under Windows, bash mangles arguments that look like
absolute POSIX paths into DOS paths. So we have to retain the level
of normalization done by normalize_path_copy() to convert the
bash-mangled DOS paths (which contain backslashes) into paths that use
forward slashes.

We currently just look at raw blob data when using "-S" to
pickaxe. This is mostly historical, as pickaxe predates the
textconv feature. If the user has bothered to define a
textconv filter, it is more likely that their search string will be
on the textconv output, as that is what they will see in the
diff (and we do not even provide a mechanism for them to
search for binary needles that contain NUL characters).
This patch teaches "-S" to use textconv, just as we
already do for "-G".
If we are given an empty pickaxe needle like "git log -S ''",
it is impossible for us to find anything (because no matter
what the content, the count will always be 0). We currently
check this at the lowest level of contains(). Let's hoist
the logic much earlier to has_changes(), so that it is
simpler to return our answer before loading any blob data.
diff_grep: use textconv buffers for add/deleted files
If you use "-G" to grep a diff, we will apply a configured
textconv filter to the data before generating the diff.
However, if the diff is an addition or deletion, we do not
bother running the diff at all, and just look for the token
in the added (or removed) content. This works because we
know that the diff must contain every line of content.
However, while we used the textconv-derived buffers in the
regular diff, we accidentally passed the original unmodified
buffers to regexec when checking the added or removed
content. This could lead to an incorrect answer.
Worse, in some cases we might have a textconv buffer but no
original buffer (e.g., if we pulled the textconv data from
cache, or if we reused a working tree file when generating
it). In that case, we could actually feed NULL to regexec
and segfault.
