Standard Windows type systems define CLSID_InternetSecurityManager
and IID_IInternetSecurityManager, but MinGW lacks these definitions.
As a result, we must hardcode these definitions ourselves. However,
we should not use a public struct with those names, lest another
library do the same thing and consumers cannot link to both.
Fix the possibility of returning successfully from ssh_stream_read()
with *bytes_read < 0. This would occur if stdout channel read resulted
in 0, and stderr channel read failed afterwards.
If the header doesn't look like a header (e.g. if it doesn't have a ":"
or if it has newlines), report "custom HTTP header '%s' is malformed".
If the header has the same name as a header already set by libgit2 (e.g.
"Host"), report "HTTP header '%s' is already set by libgit2".
libgit2 implementations of smart subtransports can simply reach through
the structure, but external implementors cannot.
Add these two functions as a way for the smart subtransports to get the
callbacks as set by the user.
When we ask for credentials, the user may choose to return EUSER to
indicate that an error has happened on its end and it wants to be given
back control.
We must therefore pass that back to the user instead of mentioning that
it was on_headers_complete() that returned an error code. Since we can,
we return the exact error code from the user (other than PASSTHROUGH)
since it doesn't cost anything, though using other error codes aren't
recommended.
The header src/cc-compat.h defines portable format specifiers PRIuZ, PRIdZ, and PRIxZ. The original report highlighted the need to use these specifiers in examples/network/fetch.c. For this commit, I checked all C source and header files not in deps/ and transitioned to the appropriate format specifier where appropriate.
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.
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.
Let `ssh_stream_free()` take a NULL stream, as free functions should,
and remove the check from the connection setup.
The connection setup would not need the check anyhow, as we always have
a stream by the time we reach this code.
