- [BUGFIX] If FIN or RST not received, don't delay stream destruction.
- [OPTIMIZATION] Speed up HPACK encoder by using same hash value to
search static and dynamic tables.
- [BUGFIX] Use correct public key from PUBS based on KEXS index.
- [BUGFIX] Check flags before dispatching writes, avoiding assert.
- [BUGFIX] Set :scheme to "https" (instead of "HTTP").
- [BUGFIX] Check buffer bounds when looking up version in 0-RTT blob.
- [BUGFIX] http_client: don't fetch 0-rtt info if handshake failed.
- Log number of pacer calls at DEBUG, rather than NOTICE, level.
- [BUGFIX] Q044: don't encode packet number in 6 bytes. Six-byte
packet number encoding does not exist in Q044. This fixes a
regression introduced in '[BUGFIX] Buffered packets can contain
ACK frames' -- we need to keep QUIC version in mind when selecting
the longest possible packet number encoding used for the buffered
packet that carries the ACK.
- [BUGFIX] Do not increase CWND when timeout occurs.
- http_client: support setting handshake timeout on command line.
Use -o handshake_to=timeout.
- http_client: use -k to connect UDP socket to pick up ICMP errors.
- http_client: allow pathless mode, when only handshake is performed
without issuing any requests. This can be done by simply not
specifying a -p flag on the command line.
- [FEATURE, API Change] 0-RTT support. Add function to export 0-RTT
information; it can be supplied to a subsequent connect() call.
- [FEATURE] Add -0 flag to http_client to exercise 0-RTT support.
- [BUGFIX] Resuscitate the Windows build.
- [BUGFIX] Send HTTP settings (max header list size) if necessary.
- [BUGFIX] Buffered packets can contain ACK frames.
- [BUGFIX] Make packet writeable once all STREAM frames are elided.
- [BUGFIX] Fix potential null dereference when realloc fails.
- cmake: simplify build configuration.
- [API Change] Can specify clock granularity in engine settings.
- [BUGFIX] Pacer uses fixed clock granularity. Since the change on
2018-04-09, it is not necessary to try to approximate the next tick
time in the pacer: it can use fix clock granularity specified by
the user.
- [BUGFIX] Do not tick constantly before handshake is done.
- [BUGFIX] Do not exit tick prematurely: reuse packet with ACK. Even
if we cannot allocate *more* packets, we could still be able to write
to one already allocated.
- [BUGFIX] Do not schedule pacer if there are no lost packets.
- [BUGFIX] http_client: make sure only one read per on_read() callback
is performed in the header conversion bypass (-B) mode.
- http_client: with -E, assign random priority when stream is created.
- [OPTIMIZATION] On immediate write, place an ACK frame into the first
buffered packet if an ACK is queued. This reduces the number of
standalone ACK packets.
- [OPTIMIZATION] Allow placing more than one STREAM frame from the same
stream into an outgoing packet. This change minimizes the number of
buffered packets required to store several small HTTP messages by
virtue of allowing more than one STREAM frame from HEADERS stream in
the same packet.
- [OPTIMIZATION] Flush headers when writing to buffered packets. This
causes the headers to be written to the same buffered packet queue,
thereby improving packet utilization, especially for small HTTP
messages.
- [FEATURE] http_client can now collect stats: time to connect, TTFB,
time to download, requests per seconds, and bandwidth. See -t flag.
- [BUGFIX] http_client: -B, -K, and -r can be used at the same time.
- [BUGFIX] http_client: do not display cert chain before each request.
Now this is only done once per connection, if the handshake is
successful and -a option is given.
- [BUGFIX] Do not wait to dispatch on_close() after reading. If a
stream is scheduled to be closed after on_read() callback returns,
close it immediately instead of waiting until the end of the tick.
If client creates new request from on_close() event, they will be
processed in the same tick instead of waiting for the next one.
- [BUGFIX] HEADERS stream is critical: always treat it with highest
priority.
- [API Change] Packet out Memory Interface (PMI) update:
- Split PMI pool return into pmi_release and pmi_return
- PMI callbacks take peer_ctx and is_ipv6 arguments
- [BUGFIX] Fix use-after-free when certificate is updated
- Silence gcc warning in optimized mode by performing useless
initialization
- cmake: use the standard variable CMAKE_BUILD_TYPE instead of
DEVEL_MODE
- [API Change] Disable packet sending if full batch cannot be sent
If lsquic_packets_out_f() cannot send the whole batch, disable
packet sending until lsquic_engine_send_unsent_packets() is called.
- [BUGFIX] Handle case when STREAM frame does not fit.
- [BUGFIX] Always allow incoming STREAM frames to overlap. Peers
may send overlapping STREAM frames even if using versions older
than Q043.
- Custom header set fixes:
- set "FIN reached" flag when custom header with FIN flag is
claimed;
- do not return custom header set for a reset stream.
Add ability to create custom header set objects via callbacks.
This avoids reading and re-parsing headers from the stream.
See test/http_client.c for example implementation. (Use -B flag
to turn it on).
- 1.10.1
- [BUGFIX] process connections after each batch of packets is read
This avoids a problem of accumulating a very large list of packets
(possible when speeds are high and socket's receive buffer is large)
and processing it all at once.
- If glibc is older than 2.17, link with rt. This is necessary for
clock_getres(2).
- Add version macros to lsquic.h; remove unnecessary includes.
Use the original method of tracking connections by CIDs by default.
If zero-sized CID support is turned on, connections are tracked by
the address. A new connection is not created if another connection
is using the same network address.
The macro soup in test_common.c acquired a few more fingernails, but
this is better than maintaining (or, rather, forgetting to maintain)
two versions of the same code.
- Remove comment: MSPC is obsolete (no code changes)
- Prog: use lsquic_str2ver() when processing -o version flag
- Remove unused CTIM and SRBF transport parameters
- Disable QUIC versions Q037 and Q038 by default
- Fix Windows compilation by including compat header file in lshpack.c
- Address warnings produced by newer versions of gcc
- Future-proof: turn off -Werror
