- 2.7.1
|
|
- [BUGFIX] client: don't call ignore_init() in middle of batch send.
|
|
ignore_init() makes an assumption that the send controller has access

|
methods to delay calling ignore_init() until the engine returns all
|
|
outgoing packets that were batched.
|

|
|
|
|
2019-03-19
|
|
- 1.19.6
|
|
- [BUGFIX] Ensure that Largest Observed does not decrease in ACKs we
|
|
send. ACK frames placed in packets in buffered queues (optimization
|
|
introduced in 1.17.15) can be preceded by an ACK frame generated later.
|
|
In this case, the older ACK frame should not be sent out, as Chromium-
|
|
based servers flags decrease in the ACK frame's Largest Observed value
|
|
as an error.
|

|
|
- 1.19.4
|
|
- [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.
|
|
|
|
2019-02-18
|
|
- 1.19.3
|
|
- [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.
|
|
|
|
2019-02-11

|
- [BUGFIX] Fix Windows build.
|
|
|
|
2019-02-04
|
|
- 1.19.0
|
|
- [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.
|
|
|
|
2019-01-28
|
|
- 1.18.0
|
|
- [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.
|
|
|
|
2019-01-17
|
|
- 1.17.15
|
|
- [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.
|
|
|
|
2019-01-16
|
|
- 1.17.14
|
|
- [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.
|
|
|
|
2019-01-10
|
|
- 1.17.12
|
|
- [FEATURE] http_client can now issue parallel requests in the context
|
|
of a single connection. See -w option.
|
|
|
|
2019-01-03
|
|
- 1.17.11

- Fix strict aliasing warning in optimized compilation.
|
|
|
|
2018-12-27
|
|
- 1.17.10

|
|
again. (See the -n argument.)

|
|
|
|
2018-12-03
|
|
- 1.17.7
|
|
- [BUGFIX] Do not unset PING alarm before ringing expired alarms.
|
|
This prevented PING from ever being sent.
|
|
|
|
2018-11-29
|
|
- 1.17.6
|
|
- Add failsafe: resume sending packets after some time
|
|
|
|
The change puts a 1-second limit on the amount of time the engine
|
|
will not send packets after some packets are delayed. This makes
|
|
the library robust in case the user does not unblock the engine
|
|
explicitly using lsquic_engine_send_unsent_packets() call.
|
|
|
|
- [BUGFIX] Handle corner cases in send controller when packets are
|
|
a) delayed or b) dropped during repackaging.
|
|
- [BUGFIX] Memory leak: destroy buffered packets during controller
|
|
cleanup.
|
|
|
|
2018-11-16
|
|
- 1.17.3

|
|
- [BUGFIX] Memory leak in test_frame_rw unit test.
|
|
- [BUGFIX] Parsing packets with short IETF header: do not overwrite
|

flags. (Only a problem in unit tests -- benign otherwise.)
|
|
|
|
2018-10-16
|
|
- 1.17.0
|
|
- [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
|

2018-09-12
|
|
- 1.14.3
|
|
- [BUGFIX] Do not abort conn on STREAM frame for a reset stream
|
|
- [BUGFIX] Drop packets that would become empty due to repackaging.
|
|
Packets on the scheduled queue may be marked for repackaging.
|
|
Frames such as ACK frame that are never resent are removed from
|
|
repackaged packets. We must check that the newly repackaged packet
|
|
would not be empty. If it would be, it is destroyed instead and
|
|
the next packet on the scheduled queue is used. Note that this
|
|
change only affects the logic to return the next packet to be sent.
|
|
Lost packets that are being rescheduled are already processed in
|
|
this fashion.
|
|
- Byteswap CID before logging it - this makes it match Chrome CIDs.

(Except Q035, which is the last little-endian GQUIC version we
|
|
support.)
|
|
|
|
2018-09-06
|
|
- 1.14.0
|
|
- [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.
|
|
|
|
2018-08-27
|
|
|
|
- 1.13.0
|
|
- [FEATURE, API Change] Add ability to create custom header set

|
|
- 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

- [BUGFIX] allow multiple parallel connections by default
|
|
|
|
Use the original method of tracking connections by CIDs by default.

2018-04-23
|
|
|
|
- Fix busy loop: tickable must make progress. When connection is
|
|
self-reporting as tickable, it must make progress when ticked. There
|
|
are two issues:
|
|
1. If there are buffered packets, the connection is only tickable if
|
|
they can be sent out.
|
|
2. A connection is tickable if there are streams on the servicing
|
|
queue. When the tick occurs, we must service the stream
|
|
independent of whether any packets are sent.
|
|
- Fix assertion in pacer which can be incorrect under some

|
conditions.
|
|
- cmake: do not turn on address sanitizer if in Travis.

|
[API Change, OPTIMIZATION] Only process conns that need to be processed
|
|
|
|
The API is simplified: do not expose the user code to several
|
|
queues. A "connection queue" is now an internal concept.
|
|
The user processes connections using the single function
|
|
lsquic_engine_process_conns(). When this function is called,
|
|
only those connections are processed that need to be processed.
|
|
A connection needs to be processed when:
|
|
|
|
1. New incoming packets have been fed to the connection.
|
|
2. User wants to read from a stream that is readable.
|
|
3. User wants to write to a stream that is writeable.
|
|
4. There are buffered packets that can be sent out. (This
|
|
means that the user wrote to a stream outside of the
|
|
lsquic library callback.)
|
|
5. A control frame (such as BLOCKED) needs to be sent out.
|
|
6. A stream needs to be serviced or delayed stream needs to
|
|
be created.

7. An alarm rings.
|
|
8. Pacer timer expires.
|
|
|
|
To achieve this, the library places the connections into two
|
|
priority queues (min heaps):
|
|
|
|
1. Tickable Queue; and
|
|
2. Advisory Tick Time queue (ATTQ).
|
|
|
|
Each time lsquic_engine_process_conns() is called, the Tickable
|
|
Queue is emptied. After the connections have been ticked, they are
|
|
queried again: if a connection is not being closed, it is placed
|
|
either in the Tickable Queue if it is ready to be ticked again or
|
|
it is placed in the Advisory Tick Time Queue. It is assumed that
|
|
a connection always has at least one timer set (the idle alarm).
|
|
|
|
The connections in the Tickable Queue are arranged in the least
|
|
recently ticked order. This lets connections that have been quiet
|
|
longer to get their packets scheduled first.
|
|
|
|
This change means that the library no longer needs to be ticked
|
|
periodically. The user code can query the library when is the
|
|
next tick event and schedule it exactly. When connections are
|
|
processed, only the tickable connections are processed, not *all*
|
|
the connections. When there are no tick events, it means that no
|
|
timer event is necessary -- only the file descriptor READ event
|
|
is active.
|
|
|
|
The following are improvements and simplifications that have
|
|
been triggered:
|
|
|
|
- Queue of connections with incoming packets is gone.
|
|
- "Pending Read/Write Events" Queue is gone (along with its
|
|
history and progress checks). This queue has become the
|
|
Tickable Queue.
|
|
- The connection hash no longer needs to track the connection
|
|
insertion order.

|
- [OPTIMIZATION] Merge series of ACKs if possible
|
|
|
|
Parsed single-range ACK frames (that is the majority of frames) are
|
|
saved in the connection and their processing is deferred until the
|
|
connection is ticked. If several ACKs come in a series between
|
|
adjacent ticks, we check whether the latest ACK is a strict superset
|
|
of the saved ACK. If it is, the older ACK is not processed.
|
|
|
|
If ACK frames can be merged, they are merged and only one of them is
|
|
either processed or saved.
|
|
|
|
- [OPTIMIZATION] Speed up ACK verification by simplifying send history.
|
|
|
|
Never generate a gap in the sent packet number sequence. This reduces
|
|
the send history to a single number instead of potentially a series of
|
|
packet ranges and thereby speeds up ACK verification.
|
|
|
|
By default, detecting a gap in the send history is not fatal: only a
|
|
single warning is generated per connection. The connection can continue
|
|
to operate even if the ACK verification code is not able to detect some
|
|
inconsistencies.
|
|
|
|
- [OPTIMIZATION] Rearrange the lsquic_send_ctl struct
|
|
|
|
The first part of struct lsquic_send_ctl now consists of members that
|
|
are used in lsquic_send_ctl_got_ack() (in the absense of packet loss,
|
|
which is the normal case). To speed up reads and writes, we no longer
|
|
try to save space by using 8- and 16-bit integers. Use regular integer
|
|
width for everything.
|
|
|
|
- [OPTIMIZATION] Cache size of sent packet.
|
|
|
|
- [OPTIMIZATION] Keep track of the largest ACKed in packet_out
|
|
|
|
Instead of parsing our own ACK frames when packet has been acked,
|
|
use the value saved in the packet_out structure when the ACK frame
|
|
was generated.
|
|
|
|
- [OPTIMIZATION] Take RTT sampling conditional out of ACK loop
|
|
|
|
- [OPTIMIZATION] ACK processing: only call clock_gettime() if needed
|
|
|
|
- [OPTIMIZATION] Several code-level optimizations to ACK processing.

|
|
|
- [API Change] Sendfile-like functionality is gone. The stream no
|
|
longer opens files and deals with file descriptors. (Among other
|
|
things, this makes the code more portable.) Three writing functions
|
|
are provided:
|
|
|
|
lsquic_stream_write
|
|
lsquic_stream_writev
|
|
lsquic_stream_writef (NEW)
|
|
|
|
lsquic_stream_writef() is given an abstract reader that has function
|
|
pointers for size() and read() functions which the user can implement.
|
|
This is the most flexible way. lsquic_stream_write() and
|
|
lsquic_stream_writev() are now both implemented as wrappers around
|
|
lsquic_stream_writef().
|
|
|
|
- [OPTIMIZATION] When writing to stream, be it within or without the
|
|
on_write() callback, place data directly into packet buffer,
|
|
bypassing auxiliary data structures. This reduces amount of memory
|
|
required, for the amount of data that can be written is limited
|
|
by the congestion window.
|
|
|
|
To support writes outside the on_write() callback, we keep N
|
|
outgoing packet buffers per connection which can be written to
|
|
by any stream. One half of these are reserved for the highest
|
|
priority stream(s), the other half for all other streams. This way,
|
|
low-priority streams cannot write instead of high-priority streams
|
|
and, on the other hand, low-priority streams get a chance to send
|
|
their packets out.
|
|
|
|
The algorithm is as follows:
|
|
|
|
- When user writes to stream outside of the callback:
|
|
- If this is the highest priority stream, place it onto the
|
|
reserved N/2 queue or fail.
|
|
(The actual size of this queue is dynamic -- MAX(N/2, CWND) --
|
|
rather than N/2, allowing high-priority streams to write as
|
|
much as can be sent.)
|
|
- If the stream is not the highest priority, try to place the
|
|
data onto the reserved N/2 queue or fail.
|
|
- When tick occurs *and* more packets can be scheduled:
|
|
- Transfer packets from the high N/2 queue to the scheduled
|
|
queue.
|
|
- If more scheduling is allowed:
|
|
- Call on_write callbacks for highest-priority streams,
|
|
placing resulting packets directly onto the scheduled queue.
|
|
- If more scheduling is allowed:
|
|
- Transfer packets from the low N/2 queue to the scheduled
|
|
queue.
|
|
- If more scheduling is allowed:
|
|
- Call on_write callbacks for non-highest-priority streams,
|
|
placing resulting packets directly onto the scheduled queue
|
|
|
|
The number N is currently 20, but it could be varied based on
|
|
resource usage.
|
|
|
|
- If stream is created due to incoming headers, make headers readable
|
|
from on_new.
|
|
|
|
- Outgoing packets are no longer marked non-writeable to prevent placing
|
|
more than one STREAM frame from the same stream into a single packet.
|
|
This property is maintained via code flow and an explicit check.
|
|
Packets for stream data are allocated using a special function.
|
|
|
|
- STREAM frame elision is cheaper, as we only perform it if a reset
|
|
stream has outgoing packets referencing it.
|
|
|
|
- lsquic_packet_out_t is smaller, as stream_rec elements are now
|
|
inside a union.
