Tatsuhiro Tsujikawa 7b9a8acc22 Add HPACK deflation API 2014-05-13 23:42:55 +09:00
Tatsuhiro Tsujikawa ab76468971 Return NGHTTP2_ERR_BUFFER_ERROR from nghttp2_hd_{deflate,inflate}_hd
It is generally useful to know what is the cause of the error.  Since
we expose HPACK API, it is friendly to tell application the
insufficient buffer size is a culprit.

Tatsuhiro Tsujikawa bc6d952361 Check max SETTINGS_HEADER_TABLE_SIZE in nghttp2_iv_check()
Hide NGHTTP2_MAX_HEADER_TABLE_SIZE from public API.  Now it is defined
as ((1u << 31) - 1) in nghttp2_frame.h, which is sufficiently big
enough.

Tatsuhiro Tsujikawa 9683f88e6a Add NGHTTP2_DEFAULT_HEADER_TABLE_SIZE macro
Use this macro in Python sources.  Python module constant
HD_DEFLATE_HD_TABLE_BUFSIZE_MAX was renamed as
DEFLATE_MAX_HEADER_TABLE_SIZE since the previous name was awkward.

Tatsuhiro Tsujikawa d2890dfb91 Remove adjust_priority_callback
Since we have stream ID immediately available from nghttp2_submit_*,
we don't need adjust_priority_callback.

Tatsuhiro Tsujikawa e8de437d5c Return new stream ID from nghttp2_submit_{request, headers, push_promise}
Previously stream ID was assigned just before HEADERS or PUSH_PROMISE
was serialized and nghttp2_submit_{request, headers, push_promise} did
not return stream ID.  The application has to check assigned stream ID
using before_frame_send_callback.  Now it is apparent that priority is
meant to DATA transfer only.  Also application can reorder the
requests if it wants. Therefore we can assign stream ID in
nghttp2_submit_* functions and return stream ID from them.  With this
change, now application does not have to check stream ID using
before_frame_send_callback and its code will be simplified.

Tatsuhiro Tsujikawa 4f027c1562 libnghttp2: Remove dependency to zlib
We inherited gzip compression API from spdylay codebase.  In spdylay,
the cost of having such API is almost free because spdylay requires
zlib for header compression.  nghttp2 no longer uses gzip to header
compression.  zlib dependency exists just for gzip compression API,
which is not an essential.  So we decided to move gzip code to under
src and remove zlib dependency from libnghttp2 itself.  As nghttp2
package, we depend on zlib to compile tools under src.

Tatsuhiro Tsujikawa 9125499dd0 src: Implement per-frame DATA compression
Currently, nghttpd server only compresses files whose extensions are
one of .html, .js, .css and .txt.  nghttp advertises its support of
per-frame compression in SETTINGS frame.  To implement this feature,
we added 2 public API: nghttp2_session_get_remote_settings() and
nghttp2_gzip_inflate_finished().

Tatsuhiro Tsujikawa 6d5f402380 Add nghttp2_adjust_priority_callback
Callback function invoked to adjust priority value for request
HEADERS.

Since the application doesn’t know stream ID when it submits
requests, it may not be able to add correct priority value to HEADERS
frame and forced to use follwing PRIORITY frame. The purpose of this
callback is give the chance to the application to adjust priority
value with the latest information it has just before transmission so
that correct priority is included in HEADERS frame and it doesn’t
have to send additional PRIORITY frame.

Tatsuhiro Tsujikawa 052be3296c Implement compressed DATA
The library interface supports compressed DATA.  The library does not
deflate nor inflate data payload.  When sending data, an application
has to compress data and set NGHTTP2_DATA_FLAG_COMPRESSED to
data_flags parameter in nghttp2_data_source_read_callback.  On
receiving, flags parameter in nghttp2_on_data_chunk_recv_callback
includes NGHTTP2_FLAG_COMPRESSED.  An application should check the
flags and inflate data as necessary.  Since compression context is per
frame, when DATA is seen in nghttp2_on_frame_recv_callback, an
application should reset compression context.

To make adding new option easier, we decided to make the details of
option struct private and hide it from public API.  We provide
functions to set individual option value.
