Check that the trailer buffer exists before attempting a client write
for trailers on stream close.
Refer to comments in https://github.com/bagder/curl/pull/564
To make sure curl doesn't allow multiplexing before a connection is
upgraded to HTTP/2 (like when Upgrade: h2c fails), we must make sure the
connection uses HTTP/2 as well and not only check what's wanted.

Previously file.txt[CR][LF] would have been returned as file.tx
(without the last t) if filetype is symlink. Now the t is
included and the internal item_length includes the zero byte.
Spotted using test 576 on Windows.
This allows the root Makefile.am to include the Makefile.inc without
causing automake to warn on it (variables named *_SOURCES are
magic). curl_SOURCES is then instead assigned properly in
src/Makefile.am only.
Closes#577
Try harder to prevent libcurl from opening up an additional socket when
CURLOPT_PIPEWAIT is set. Accomplished by letting ongoing TCP and TLS
handshakes complete first before the decision is made.
Closes#575
This makes it easier for emacs users to automatically get the right
2-space indentation when they edit curl source files.
c++-mode is in there as well because Emacs can't easily know if
something is a C or C++ header.
Closes#574
The request needs to be read and send in binary mode in order to use
CRLF instead of LF. Adding --upload-file - causes curl to read stdin
in binary mode.
The function is only present in wolfssl/cyassl if it was built with
--enable-opensslextra. With these checks added, pinning support is disabled
unless the TLS lib has that function available.
Also fix the mistake in configure that checks for the wrong lib name.
Closes#566
This commit adds trailer support in HTTP/2. In HTTP/1.1, chunked
encoding must be used to send trialer fields. HTTP/2 deprecated any
trandfer-encoding, including chunked. But trailer fields are now
always available.
Since trailer fields are relatively rare these days (gRPC uses them
extensively though), allocating buffer for trailer fields is done when
we detect that HEADERS frame containing trailer fields is started. We
use Curl_add_buffer_* functions to buffer all trailers, just like we
do for regular header fields. And then deliver them when stream is
closed. We have to be careful here so that all data are delivered to
upper layer before sending trailers to the application.
We can deliver trailer field one by one using NGHTTP2_ERR_PAUSE
mechanism, but current method is far more simple.
Another possibility is use chunked encoding internally for HTTP/2
traffic. I have not tested it, but it could add another overhead.
Closes#564
