smart transport: only clear url on hard reset
After creating a transport for a server, we expect to be able to call
`connect`, then invoke subsequent `action` calls. We provide the URL to
these `action` calls, although our built-in transports happen to ignore
it since they've already parsed it into an internal format that they
intend to use (`gitno_connection_data`).
In ca2eb4608243162a13c427e74526b6422d5a6659, we began clearing the URL
field after a connection, meaning that subsequent calls to transport
`action` callbacks would get a NULL URL, which went undetected since the
builtin transports ignore the URL when they're already connected
(instead of re-parsing it into an internal format).
Downstream custom transport implementations (eg, LibGit2Sharp) did
notice this change, however.
Since `reset_stream` is called even when we're not closing the
subtransport, update to only clear the URL when we're closing the
subtransport. This ensures that `action` calls will get the correct URL
information even after a connection.

winhttp: retry erroneously failing requests
Early Windows TLS 1.2 implementations have an issue during key exchange
with OpenSSL implementations that cause negotiation to fail with the
error "the buffer supplied to a function was too small."
This is a transient error on the connection, so when that error is
received, retry up to 5 times to create a connection to the remote
server before actually giving up.

ignore unsupported http authentication schemes
auth_context_match returns 0 instead of -1 for unknown schemes to
not fail in situations where some authentication schemes are supported
and others are not.
apply_credentials is adjusted to handle auth_context_match returning
0 without producing authentication context.

smart_pkt: do not accept callers passing in no line length
Right now, we simply ignore the `linelen` parameter of
`git_pkt_parse_line` in case the caller passed in zero. But in fact, we
never want to assume anything about the provided buffer length and
always want the caller to pass in the available number of bytes.
And in fact, checking all the callers, one can see that the funciton is
never being called in case where the buffer length is zero, and thus we
are safe to remove this check.

smart_pkt: return parsed length via out-parameter
The `parse_len` function currently directly returns the parsed length of
a packet line or an error code in case there was an error. Instead,
convert this to our usual style of using the return value as error code
only and returning the actual value via an out-parameter. Thus, we can
now convert the output parameter to an unsigned type, as the size of a
packet cannot ever be negative.
While at it, we also move the check whether the input buffer is long
enough into `parse_len` itself. We don't really want to pass around
potentially non-NUL-terminated buffers to functions without also passing
along the length, as this is dangerous in the unlikely case where other
callers for that function get added. Note that we need to make sure
though to not mess with `GIT_EBUFS` error codes, as these indicate not
an error to the caller but that he needs to fetch more data.

smart_pkt: reorder and rename parameters of `git_pkt_parse_line`
The parameters of the `git_pkt_parse_line` function are quite confusing.
First, there is no real indicator what the `out` parameter is actually
all about, and it's not really clear what the `bufflen` parameter refers
to. Reorder and rename the parameters to make this more obvious.

smart_pkt: fix buffer overflow when parsing "unpack" packets
When checking whether an "unpack" packet returned the "ok" status or
not, we use a call to `git__prefixcmp`. In case where the passed line
isn't properly NUL terminated, though, this may overrun the line buffer.
Fix this by using `git__prefixncmp` instead.

smart_pkt: fix "ng" parser accepting non-space character
When parsing "ng" packets, we blindly assume that the character
immediately following the "ng" prefix is a space and skip it. As the
calling function doesn't make sure that this is the case, we can thus
end up blindly accepting an invalid packet line.
Fix the issue by using `git__prefixncmp`, checking whether the line
starts with "ng ".

smart_pkt: fix buffer overflow when parsing "ok" packets
There are two different buffer overflows present when parsing "ok"
packets. First, we never verify whether the line already ends after
"ok", but directly go ahead and also try to skip the expected space
after "ok". Second, we then go ahead and use `strchr` to scan for the
terminating newline character. But in case where the line isn't
terminated correctly, this can overflow the line buffer.
Fix the issues by using `git__prefixncmp` to check for the "ok " prefix
and only checking for a trailing '\n' instead of using `memchr`. This
also fixes the issue of us always requiring a trailing '\n'.

smart_pkt: fix buffer overflow when parsing "ACK" packets
We are being quite lenient when parsing "ACK" packets. First, we didn't
correctly verify that we're not overrunning the provided buffer length,
which we fix here by using `git__prefixncmp` instead of
`git__prefixcmp`. Second, we do not verify that the actual contents make
any sense at all, as we simply ignore errors when parsing the ACKs OID
and any unknown status strings. This may result in a parsed packet
structure with invalid contents, which is being silently passed to the
caller. This is being fixed by performing proper input validation and
checking of return codes.

smart_pkt: adjust style of "ref" packet parsing function
While the function parsing ref packets doesn't have any immediately
obvious buffer overflows, it's style is different to all the other
parsing functions. Instead of checking buffer length while we go, it
does a check up-front. This causes the code to seem a lot more magical
than it really is due to some magic constants. Refactor the function to
instead make use of the style of other packet parser and verify buffer
lengths as we go.

smart_pkt: check whether error packets are prefixed with "ERR "
In the `git_pkt_parse_line` function, we determine what kind of packet
a given packet line contains by simply checking for the prefix of that
line. Except for "ERR" packets, we always only check for the immediate
identifier without the trailing space (e.g. we check for an "ACK"
prefix, not for "ACK "). But for "ERR" packets, we do in fact include
the trailing space in our check. This is not really much of a problem at
all, but it is inconsistent with all the other packet types and thus
causes confusion when the `err_pkt` function just immediately skips the
space without checking whether it overflows the line buffer.
Adjust the check in `git_pkt_parse_line` to not include the trailing
space and instead move it into `err_pkt` for consistency.

smart_pkt: explicitly avoid integer overflows when parsing packets
When parsing data, progress or error packets, we need to copy the
contents of the rest of the current packet line into the flex-array of
the parsed packet. To keep track of this array's length, we then assign
the remaining length of the packet line to the structure. We do have a
mismatch of types here, as the structure's `len` field is a signed
integer, while the length that we are assigning has type `size_t`.
On nearly all platforms, this shouldn't pose any problems at all. The
line length can at most be 16^4, as the line's length is being encoded
by exactly four hex digits. But on a platforms with 16 bit integers,
this assignment could cause an overflow. While such platforms will
probably only exist in the embedded ecosystem, we still want to avoid
this potential overflow. Thus, we now simply change the structure's
`len` member to be of type `size_t` to avoid any integer promotion.

smart_pkt: honor line length when determining packet type
When we parse the packet type of an incoming packet line, we do not
verify that we don't overflow the provided line buffer. Fix this by
using `git__prefixncmp` instead and passing in `len`. As we have
previously already verified that `len <= linelen`, we thus won't ever
overflow the provided buffer length.

When parsing an "ng" packet, we keep track of both the current position
as well as the remaining length of the packet itself. But instead of
taking care not to exceed the length, we pass the current pointer's
position to `strchr`, which will search for a certain character until
hitting NUL. It is thus possible to create a crafted packet which
doesn't contain a NUL byte to trigger an out-of-bounds read.
Fix the issue by instead using `memchr`, passing the remaining length as
restriction. Furthermore, verify that we actually have enough bytes left
to produce a match at all.

transports: local: fix assert when fetching into repo with symrefs
When fetching into a repository which has symbolic references via the
"local" transport we run into an assert. The assert is being triggered
while we negotiate the packfile between the two repositories. When
hiding known revisions from the packbuilder revwalk, we unconditionally
hide all references of the local refdb. In case one of these references
is a symbolic reference, though, this means we're trying to hide a
`NULL` OID, which triggers the assert.
Fix the issue by only hiding OID references from the revwalk. Add a test
to catch this issue in the future.

transports: ssh: replace deprecated function `libssh2_session_startup`
The function `libssh2_session_startup` has been deprecated since libssh2
version 1.2.8 in favor of `libssh2_session_handshake` introduced in the
same version. libssh2 1.2.8 was released in April 2011, so it is already
seven years old. It is available in Debian Wheezy, Ubuntu Trusty and
CentOS 7.4, so the most important and conservative distros already have
it available. As such, it seems safe to just use the new function.

transports: ssh: disconnect session before freeing it
The function `ssh_stream_free` takes over the responsibility of closing
channels and streams just before freeing their memory, but it does not
do so for the session. In fact, we never disconnect the session
ourselves at all, as libssh2 will not do so itself upon freeing the
structure. Quoting the documentation of `libssh2_session_free`:
> Frees all resources associated with a session instance. Typically
> called after libssh2_session_disconnect_ex,
The missing disconnect probably stems from a misunderstanding what it
actually does. As we are already closing the TCP socket ourselves, the
assumption was that no additional disconnect is required. But calling
`libssh2_session_disconnect` will notify the server that we are cleanly
closing the connection, such that the server can free his own resources.
Add a call to `libssh2_session_disconnect` to fix that issue.

Versions of Windows prior to Windows 8 do not enable TLS 1.2 by default,
though support may exist. Try to enable TLS 1.2 support explicitly on

This request may fail if the operating system does not have TLS 1.2
support - the initial release of Vista lacks TLS 1.2 support (though
it is available as a software update) and XP completely lacks TLS 1.2
support. If this request does fail, the HTTP context is still valid,
and still maintains the original protocol support. So we ignore the

transports: local: fix memory leak in reference walk
Upon downloading the pack file, the local transport will iterate through

tricky though in that it requires the passed callback to free the

Fix the memory leak by freeing all passed references in the callback.

transports: smart: fix memory leak when skipping symbolic refs
When we setup the revision walk for negotiating references with a
remote, we iterate over all references, ignoring tags and symbolic
references. While skipping over symbolic references, we forget to free
the looked up reference, resulting in a memory leak when the next
iteration simply overwrites the variable.
Fix that issue by freeing the reference at the beginning of each
iteration and collapsing return paths for error and success.

Make sure to always include "common.h" first
Next to including several files, our "common.h" header also declares
various macros which are then used throughout the project. As such, we
have to make sure to always include this file first in all
implementation files. Otherwise, we might encounter problems or even
silent behavioural differences due to macros or defines not being
defined as they should be. So in fact, our header and implementation
files should make sure to always include "common.h" first.
This commit does so by establishing a common include pattern. Header
files inside of "src" will now always include "common.h" as its first
other file, separated by a newline from all the other includes to make
it stand out as special. There are two cases for the implementation
files. If they do have a matching header file, they will always include
this one first, leading to "common.h" being transitively included as
first file. If they do not have a matching header file, they instead
include "common.h" as first file themselves.
This fixes the outlined problems and will become our standard practice
for header and source files inside of the "src/" from now on.

smart_protocol: fix parsing of server ACK responses
Fix ACK parsing in wait_while_ack() internal function. This patch
handles the case where multi_ack_detailed mode sends 'ready' ACKs. The
existing functionality would bail out too early, thus causing the
processing of the ensuing packfile to fail if/when 'ready' ACKs were
sent.

buffer: rely on `GITERR_OOM` set by `git_buf_try_grow`
The function `git_buf_try_grow` consistently calls `giterr_set_oom`
whenever growing the buffer fails due to insufficient memory being
available. So in fact, we do not have to do this ourselves when a call
to any buffer-growing function has failed due to an OOM situation. But
we still do so in two functions, which this patch cleans up.

repository: use `git_repository_item_path`
The recent introduction of the commondir variable of a repository
requires callers to distinguish whether their files are part of
the dot-git directory or the common directory shared between
multpile worktrees. In order to take the burden from callers and
unify knowledge on which files reside where, the
`git_repository_item_path` function has been introduced which
encapsulate this knowledge.
Modify most existing callers of `git_repository_path` to use
`git_repository_item_path` instead, thus making them implicitly
aware of the common directory.

smart_pkt: treat empty packet lines as error
The Git protocol does not specify what should happen in the case
of an empty packet line (that is a packet line "0004"). We
currently indicate success, but do not return a packet in the
case where we hit an empty line. The smart protocol was not
prepared to handle such packets in all cases, though, resulting
in a `NULL` pointer dereference.
Fix the issue by returning an error instead. As such kind of
packets is not even specified by upstream, this is the right
thing to do.

smart_pkt: verify packet length exceeds PKT_LEN_SIZE
Each packet line in the Git protocol is prefixed by a four-byte
length of how much data will follow, which we parse in
`git_pkt_parse_line`. The transmitted length can either be equal
to zero in case of a flush packet or has to be at least of length
four, as it also includes the encoded length itself. Not
checking this may result in a buffer overflow as we directly pass
the length to functions which accept a `size_t` length as
parameter.
Fix the issue by verifying that non-flush packets have at least a
length of `PKT_LEN_SIZE`.

http: bump the pretend git version in the User-Agent
We want to keep the git UA in order for services to recognise that we're
a Git client and not a browser. But in order to stop dumb HTTP some
services have blocked UAs that claim to be pre-1.6.6 git.
Thread these needles by using the "git/2.0" prefix which is still close
enough to git's yet distinct enough that you can tell it's us.

transports: smart: abort receiving packets on end of stream
When trying to receive packets from the remote, we loop until
either an error distinct to `GIT_EBUFS` occurs or until we
successfully parsed the packet. This does not honor the case
where we are looping over an already closed socket which has no
more data, leaving us in an infinite loop if we got a bogus
packet size or if the remote hang up.
Fix the issue by returning `GIT_EEOF` when we cannot read data
from the socket anymore.

transports: smart: abort ref announcement on early end of stream
When reading a server's reference announcements via the smart
protocol, we expect the server to send multiple flushes before
the protocol is finished. If we fail to receive new data from the
socket, we will only return an end of stream error if we have not
seen any flush yet.
This logic is flawed in that we may run into an infinite loop
when receiving a server's reference announcement with a bogus
flush packet. E.g. assume the last flushing package is changed to
not be '0000' but instead any other value. In this case, we will
still await one more flush package and ignore the fact that we
are not receiving any data from the socket, causing an infinite
loop.
Fix the issue by always returning `GIT_EEOF` if the socket
indicates an end of stream.

transports: http: reset `connected` flag when re-connecting transport
When calling `http_connect` on a subtransport whose stream is already
connected, we first close the stream in case no keep-alive is in use.
When doing so, we do not reset the transport's connection state,
though. Usually, this will do no harm in case the subsequent connect
will succeed. But when the connection fails we are left with a
substransport which is tagged as connected but which has no valid
stream attached.
Fix the issue by resetting the subtransport's connected-state when
closing its stream in `http_connect`.

transports: smart: fix potential invalid memory dereferences
When we receive a packet of exactly four bytes encoding its
length as those four bytes it can be treated as an empty line.
While it is not really specified how those empty lines should be
treated, we currently ignore them and do not return an error when
trying to parse it but simply advance the data pointer.
Callers invoking `git_pkt_parse_line` are currently not prepared
to handle this case as they do not explicitly check this case.
While they could always reset the passed out-pointer to `NULL`
before calling `git_pkt_parse_line` and determine if the pointer
has been set afterwards, it makes more sense to update
`git_pkt_parse_line` to set the out-pointer to `NULL` itself when
it encounters such an empty packet. Like this it is guaranteed
that there will be no invalid memory references to free'd
pointers.
As such, the issue has been fixed such that `git_pkt_parse_line`
always sets the packet out pointer to `NULL` when an empty packet
has been received and callers check for this condition, skipping
such packets.
