This patch fixes the loss of information when computing the delivery rate (quic_cc_drs.c) on links with very low latency due to usage of 32bits variables with the millisecond as precision. Initialize the quic_conn task with TASK_F_WANTS_TIME flag ask it to ask the scheduler to update the call date of this task. This allows this task to get a nanosecond resolution on the call date calling task_mono_time(). This is enabled only for congestion control algorithms with delivery rate estimation support (BBR only at this time). Store the send date with nanosecond precision of each TX packet into ->time_sent_ns new quic_tx_packet struct member to store the date a packet was sent in nanoseconds thanks to task_mono_time(). Make use of this new timestamp by the delivery rate estimation algorithm (quic_cc_drs.c). Rename current ->time_sent member from quic_tx_packet struct to ->time_sent_ms to distinguish the unit used by this variable (millisecond) and update the code which uses this variable. The logic found in quic_loss.c is not modified at all. Must be backported to 3.1.
HAProxy
HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
Installation
The INSTALL file describes how to build HAProxy. A list of packages is also available on the wiki.
Getting help
The discourse and the mailing-list are available for questions or configuration assistance. You can also use the slack or IRC channel. Please don't use the issue tracker for these.
The issue tracker is only for bug reports or feature requests.
Documentation
The HAProxy documentation has been split into a number of different files for ease of use. It is available in text format as well as HTML. The wiki is also meant to replace the old architecture guide.
Please refer to the following files depending on what you're looking for:
- INSTALL for instructions on how to build and install HAProxy
- BRANCHES to understand the project's life cycle and what version to use
- LICENSE for the project's license
- CONTRIBUTING for the process to follow to submit contributions
The more detailed documentation is located into the doc/ directory:
- doc/intro.txt for a quick introduction on HAProxy
- doc/configuration.txt for the configuration's reference manual
- doc/lua.txt for the Lua's reference manual
- doc/SPOE.txt for how to use the SPOE engine
- doc/network-namespaces.txt for how to use network namespaces under Linux
- doc/management.txt for the management guide
- doc/regression-testing.txt for how to use the regression testing suite
- doc/peers.txt for the peers protocol reference
- doc/coding-style.txt for how to adopt HAProxy's coding style
- doc/internals for developer-specific documentation (not all up to date)
