Function was added in commit 2c982daa2e on October 5, 2011,
and removed in commit 41fb1ca0ec on October 29, 2012.
Given the length of time it's gone unused, it's safe to remove now.
This reverts commit 969d4b703c.
This was a fluke from Coverity. The length to all the APIs in the
library is supposed to be passed in as nibbles, not bytes. Passing it as
bytes would prevent us from parsing uneven-sized SHA1 strings.
Also, the rest of the library was still using nibbles (including
revparse and the odb_prefix APIs), so this change was seriously breaking
things in unexpected ways. ^^
When diffing the index with the workdir and GIT_DIFF_UPDATE_INDEX has been passed,
the previous implementation was always writing the index to disk even if it wasn't
modified.
When a refspec contains no rhs and thus won't cause an explicit update,
we skip all the logic, but that means that we don't update FETCH_HEAD
with it, which is what the implicit rhs is.
Add another bit of logic which puts those remote heads in the list of
updates so we put them into FETCH_HEAD.
When we don't own a buffer (asize=0) we currently allow the usage of
grow to copy the memory into a buffer we do own. This muddles the
meaning of grow, and lets us be a bit cavalier with ownership semantics.
Don't allow this any more. Usage of grow should be restricted to buffers
which we know own their own memory. If unsure, we must not attempt to
modify it.
Always set `GIT_DIFF_PATCH_DIFFABLE` for all files, regardless of
binary-ness, so that the binary callback is invoked to either
show the binary contents, or just print the standard "Binary files
differ" message. We may need to do deeper inspection for binary
files where we have avoided loading the contents into a file map.
If the libcurl stream is available, use that as the underlying stream
instead of the socket stream. This allows us to set a proxy for HTTPS
connections.
The TLS streams talk over the curl stream themselves, so we don't need
to ask for it explicitly. Do so in the case of the non-encrypted one so
we can still make use proxies in that case.
When linking against libcurl, use it as the underlying transport instead
of straight sockets. We can't quite just give over the file descriptor,
as curl puts it into non-blocking mode, so we build a custom BIO so
OpenSSL sends the data through our stream, be it the socket or curl
streams.
If the stream claims to support this feature, we can let the transport
set the proxy.
We also set HTTPPROXYTUNNEL option so curl can create a tunnel through
the proxy which lets us create our own TLS session (if needed).
cURL has a mode in which it acts a lot like our streams, providing send
and recv functions and taking care of the TLS and proxy setup for us.
Implement a new stream which uses libcurl instead of raw sockets or the
TLS libraries directly. This version does not support reporting
certificates or proxies yet.
