86f9515708 config: resolve symlinks in conditional include's patterns
$GIT_DIR returned by get_git_dir() is normalized, with all symlinks
resolved (see setup_work_tree function). In order to match paths (or
patterns) against $GIT_DIR char-by-char, they have to be normalized
too. There is a note in config.txt about this, that the user need to
resolve symlinks by themselves if needed.

The problem is, we allow certain path expansion, '~/' and './', for
convenience and can't ask the user to resolve symlinks in these
expansions. Make sure the expanded paths have all symlinks resolved.

PS. The strbuf_realpath(&text, get_git_dir(), 1) is still needed because
get_git_dir() may return relative path.

4aad2f1627 path.c: and an option to call real_path() in expand_user_path()
In the next patch we need the ability to expand '~' to
real_path($HOME). But we can't do that from outside because '~' is part
of a pattern, not a true path. Add an option to expand_user_path() to do
so.

210e5dba0b t2027: avoid using pipes
Whenever a git command is present in the upstream of a pipe, its failure
gets masked by piping. Hence we should avoid it for testing the
upstream git command. By writing out the output of the git command to
a file, we can test the exit codes of both the commands as a failure exit
code in any command is able to stop the && chain.

68fb02e40d get_ref_dir(): don't call read_loose_refs() for "refs/bisect"
Since references under "refs/bisect/" are per-worktree, they have to
be sought in the worktree rather than in the main repository. But
since loose references are found by traversing directories, the
reference iterator won't even get the idea to look for a
"refs/bisect/" directory in the worktree if there is not a directory
with that name in the main repository. Thus `get_ref_dir()` manually
inserts a dir_entry for "refs/bisect/" whenever it reads the entry for
"refs/".

The current code then immediately calls `read_loose_refs()` on that
directory. But since the dir_entry is created with its `incomplete`
flag set, any traversal that gets to this point will read the
directory automatically. So there is no need to call
`read_loose_refs()` explicitly; the lazy mechanism suffices.

And in fact, the attempt to `read_loose_refs()` was broken anyway.
That function needs its `dirname` argument to have a trailing `/`
character, but the invocation here was passing it "refs/bisect"
without a trailing slash. So `read_loose_refs()` would read
`$GIT_DIR/refs/bisect" correctly, but if it found an entry "foo" in
that directory, it would try to read "$GIT_DIR/refs/bisectfoo".
Normally it wouldn't find anything at that path, but the failure was
canceled out because `get_ref_dir()` *also* forgot to reset the
`REF_INCOMPLETE` bit on the dir_entry. So the read was attempted again
when it was accessed, via the lazy mechanism, and this time the read
was done correctly.

This code has been broken since it was first introduced.

2f40e95472 files-backend: avoid ref api targeting main ref store
A small step towards making files-backend work as a non-main ref store
using the newly added store-aware API.

For the record, `join` and `nm` on refs.o and files-backend.o tell me
that files-backend no longer uses functions that default to
get_main_ref_store().

I'm not yet comfortable at the idea of removing
files_assert_main_repository() (or converting REF_STORE_MAIN to
REF_STORE_WRITE). More staring and testing is required before that can
happen. Well, except peel_ref(). I'm pretty sure that function is safe.

9e7ec634a1 files-backend: replace submodule_allowed check in files_downcast()
files-backend.c is unlearning submodules. Instead of having a specific
check for submodules to see what operation is allowed, files backend
now takes a set of flags at init. Each operation will check if the
required flags is present before performing.

For now we have four flags: read, write and odb access. Main ref store
has all flags, obviously, while submodule stores are read-only and have
access to odb (*).

The "main" flag stays because many functions in the backend calls
frontend ones without a ref store, so these functions always target the
main ref store. Ideally the flag should be gone after ref-store-aware
api is in place and used by backends.

(*) Submodule code needs for_each_ref. Try take REF_STORE_ODB flag
out. At least t3404 would fail. The "have access to odb" in submodule is
a bit hacky since we don't know from he whether add_submodule_odb() has
been called.

882add136f difftool: fix use-after-free
The left and right base directories were pointed to the buf field of
two strbufs, which were subject to change.

A contrived test case shows the problem where a file with a long enough
name to force the strbuf to grow is up-to-date (hence the code path is
used where the work tree's version of the file is reused), and then a
file that is not up-to-date needs to be written (hence the code path is
used where checkout_entry() uses the previously recorded base_dir that
is invalid by now).

Let's just copy the base_dir strings for use with checkout_entry(),
never touch them until the end, and release them then. This is an easily
verifiable fix (as opposed to the next-obvious alternative: to re-set
base_dir after every loop iteration).

This fixes https://github.com/git-for-windows/git/issues/1124

ae51d91105 http: fix the silent ignoring of proxy misconfiguraion
Earlier, the whole http.proxy option string was passed to curl without
any preprocessing so curl could complain about the invalid proxy
configuration.

After the commit 372370f167 ("http: use credential API to handle proxy
authentication", 2016-01-26), if the user specified an invalid HTTP
proxy option in the configuration, then the option parsing silently
fails and NULL will be passed to curl as a proxy. This forces curl to
fall back to detecting the proxy configuration from the environment,
causing the http.proxy option ignoring.

Fix this issue by checking the proxy option parsing result. If parsing
failed then print an error message and die. Such behaviour allows the
user to quickly figure the proxy misconfiguration and correct it.

57415089bd http: honor empty http.proxy option to bypass proxy
Curl distinguishes between an empty proxy address and a NULL proxy
address. In the first case it completely disables proxy usage, but if
the proxy address option is NULL then curl attempts to determine the
proxy address from the http_proxy environment variable.

According to the documentation, if the http.proxy option is set to an
empty string, git should bypass proxy and connect to the server
directly:

    export http_proxy=http://network-proxy/
    cd ~/foobar-project
    git config remote.origin.proxy ""
    git fetch

Previously, proxy host was configured by one line:

    curl_easy_setopt(result, CURLOPT_PROXY, curl_http_proxy);

Commit 372370f167 ("http: use credential API to handle proxy
authentication", 2016-01-26) parses the proxy option, then extracts the
proxy host address and updates the curl configuration, making the
previous call a noop:

    credential_from_url(&proxy_auth, curl_http_proxy);
    curl_easy_setopt(result, CURLOPT_PROXY, proxy_auth.host);

But if the proxy option is empty then the proxy host field becomes NULL.
This forces curl to fall back to detecting the proxy configuration from
the environment, causing the http.proxy option to not work anymore.

Fix this issue by explicitly handling http.proxy being set the empty
string. This also makes the code a bit more clear and should help us
avoid such regressions in the future.

17b254cda6 diff: submodule inline diff to initialize env array.
David reported:
> When I try to run `git diff --submodule=diff` in a submodule which has
> it's own submodules that have changes I get the error: fatal: bad
> object.

This happens, because we do not properly initialize the environment
in which the diff is run in the submodule. That means we inherit the
environment from the main process, which sets environment variables.
(Apparently we do set environment variables which we do not set
when not in a submodules, i.e. the .git directory is linked)

This commit, just like fd47ae6a5b (diff: teach diff to display
submodule difference with an inline diff, 2016-08-31) introduces bad
test code (i.e. hard coded hash values), which will be cleanup up in
a later patch.

51054177b3 index-pack: detect local corruption in collision check
When we notice that we have a local copy of an incoming
object, we compare the two objects to make sure we haven't
found a collision. Before we get to the actual object
bytes, though, we compare the type and size from
sha1_object_info().

If our local object is corrupted, then the type will be
OBJ_BAD, which obviously will not match the incoming type,
and we'll report "SHA1 COLLISION FOUND" (with capital
letters and everything). This is confusing, as the problem
is not a collision but rather local corruption. We should
report that instead (just like we do if reading the rest of
the object content fails a few lines later).

Note that we _could_ just ignore the error and mark it as a
non-collision. That would let you "git fetch" to replace a
corrupted object. But it's not a very reliable method for
repairing a repository. The earlier want/have negotiation
tries to get the other side to omit objects we already have,
and it would not realize that we are "missing" this
corrupted object. So we're better off complaining loudly
when we see corruption, and letting the user take more
drastic measures to repair (like making a full clone
elsewhere and copying the pack into place).

Note that the test sets transfer.unpackLimit in the
receiving repository so that we use index-pack (which is
what does the collision check). Normally for such a small
push we'd use unpack-objects, which would simply try to
write the loose object, and discard the new one when we see
that there's already an old one.

93cff9a978 sha1_loose_object_info: return error for corrupted objects
When sha1_loose_object_info() finds that a loose object file
cannot be stat(2)ed or mmap(2)ed, it returns -1 to signal an
error to the caller.  However, if it found that the loose
object file is corrupt and the object data cannot be used
from it, it stuffs OBJ_BAD into "type" field of the
object_info, but returns zero (i.e., success), which can
confuse callers.

This is due to 052fe5eac (sha1_loose_object_info: make type
lookup optional, 2013-07-12), which switched the return to a
strict success/error, rather than returning the type (but
botched the return).

Callers of regular sha1_object_info() don't notice the
difference, as that function returns the type (which is
OBJ_BAD in this case). However, direct callers of
sha1_object_info_extended() see the function return success,
but without setting any meaningful values in the object_info
struct, leading them to access potentially uninitialized
memory.

The easiest way to see the bug is via "cat-file -s", which
will happily ignore the corruption and report whatever
value happened to be in the "size" variable.

fba275dc93 contrib/git-resurrect.sh: do not write \t for HT in sed scripts
Just like we did in 0d1d6e50 ("t/t7003: replace \t with literal tab
in sed expression", 2010-08-12), avoid writing "\t" for HT in sed
scripts, which is not portable.

2a1bd45b2e name-hash: fix buffer overrun
Add check for the end of the entries for the thread partition.
Add test for lazy init name hash with specific directory structure

The lazy init hash name was causing a buffer overflow when the last
entry in the index was multiple folder deep with parent folders that
did not have any files in them.

This adds a test for the boundary condition of the thread partitions
with the folder structure that was triggering the buffer overflow.

The fix was to check if it is the last entry for the thread partition
in the handle_range_dir and not try to use the next entry in the cache.

910650d2f8 Rename sha1_array to oid_array
Since this structure handles an array of object IDs, rename it to struct
oid_array.  Also rename the accessor functions and the initialization
constant.

This commit was produced mechanically by providing non-Documentation
files to the following Perl one-liners:

    perl -pi -E 's/struct sha1_array/struct oid_array/g'
    perl -pi -E 's/\bsha1_array_/oid_array_/g'
    perl -pi -E 's/SHA1_ARRAY_INIT/OID_ARRAY_INIT/g'

Make sha1_array_for_each_unique take a callback using struct object_id.
Since one of these callbacks is an argument to for_each_abbrev, convert
those as well.  Rename various functions, replacing "sha1" with "oid".
