History¶
v8.6.0¶
(no Git tag matched)
Significant improvements:
:issue:`384` via :pr:`385`, :pr:`406`: Exposed type stubs with annotations for public API – by :user:`kasium`.
:pr:`401` (related to the :pr:`352` effort): Started reusing the the
expriration_interval
setting in the low-levelselect()
invocation, effectively reducing the system load under the Windows OS when idle, that is noticeable on low-end hardware systems – by :user:`MichaIng`.
Internal changes:
Implemented a manual-trigger-based release workflow.
Integrated publishing GitHub Releases into the workflow.
Migrated the docs theme to Furo (created by :user:`pradyunsg`).
Attempted to improve the stability of testing.
Configured the CI to test the same distribution as will be shipped.
Improved the linting setup and contributor checklists.
Stopped running tests under Ubuntu 16.04.
Tweaked the distribution packages metadata to satisfy strict checks.
Implemented distribution build reproducibility using a pip constraints lock-file.
Added per-environment lock-files into the tox test environments.
v8.5.2¶
(no Git tag matched)
:issue:`358` via :pr:`359`: Fixed a regression from :pr:`199` that made the worker threads exit on invalid connection attempts and could make the whole server unresponsive once there was no workers left. – by :user:`cameronbrunner`.
v8.5.1¶
(no Git tag matched)
:cp-issue:`1873` via :pr:`340`: Resurrected an unintentionally removed feature of interrupting a server main thread by externally assigning an exception to the
HTTPServer.interrupt
property – by :user:`liamstask`.:pr:`350`: Fixed the incarnation of an earlier regression of not resetting the serving state on
SIGINT
originally fixed by :pr:`322` and :pr:`331` but reintroduced by the changes in :pr:`311` – by :user:`liamstask`.
v8.5.0¶
(no Git tag matched)
:issue:`305` via :pr:`311`: In
ConnectionManager
, process connections as they become active rather than waiting for atick
event, addressing performance degradation introduced in v8.1.0 – by :user:`liamstask`.:issue:`341` via :pr:`342`: Suppress legitimate OS errors expected on shutdown – by :user:`webknjaz`.
v8.4.8¶
(no Git tag matched)
:issue:`317` via :pr:`337`: Fixed a regression in 8.4.5 where the connections dictionary would change size during iteration, leading to a
RuntimeError
raised in the logs – by :user:`liamstask`.
v8.4.7¶
(no Git tag matched)
:pr:`334`: Started filtering out TLS/SSL errors when the version requested by the client is unsupported – by :user:`sanderjo` and :user:`Safihre`.
v8.4.6¶
(no Git tag matched)
:issue:`328` via :pr:`322` and :pr:`331`: Fixed a regression introduced in the earlier refactoring in v8.4.4 via :pr:`309` that caused the
serve()
method to skip settingserving=False
on :py:data:SIGINT
and :py:data:SIGTERM
– by :user:`marc1n` and :user:`cristicbz`.
v8.4.5¶
(no Git tag matched)
:issue:`312` via :pr:`313`: Fixed a regression introduced in the earlier refactoring in v8.4.4 via :pr:`309` that caused the connection manager to modify the selector map while looping over it – by :user:`liamstask`.
:issue:`312` via :pr:`316`: Added a regression test for the error handling in
get_conn()
to ensure more stability – by :user:`cyraxjoe`.
v8.4.4¶
(no Git tag matched)
:issue:`304` via :pr:`309`: Refactored
ConnectionManager
to useget_map()
and reorganized the readable connection tracking – by :user:`liamstask`.:issue:`304` via :pr:`309`: Fixed the server shutdown sequence to avoid race condition resulting in accepting new connections while it is being terminated – by :user:`liamstask`.
v8.4.3¶
(no Git tag matched)
:pr:`282`: Fixed a race condition happening when an HTTP client attempts to reuse a persistent HTTP connection after it’s been discarded on the server in
HTTPRequest
but no TCP FIN packet has been received yet over the wire – by :user:`meaksh`.This change populates the
Keep-Alive
header exposing the timeout value for persistent HTTP/1.1 connections which helps mitigate such race conditions by letting the client know not to reuse the connection after that time interval.
v8.4.2¶
(no Git tag matched)
Fixed a significant performance regression introduced in v8.1.0 (:issue:`305` via :pr:`308`) - by :user:`mar10`.

(no Git tag matched)
Converted management from low-level
select()
to high-levelselectors
(:issue:`249` via :pr:`301`) - by :user:`tommilligan`.This change also introduces a conditional dependency on
selectors2
as a fall-back for legacy Python interpreters.
v8.3.1¶

(no Git tag matched)
:issue:`17` via :pr:`25`: Instead of a read_headers function, cheroot now supplies a
HeaderReader
class to perform the same function.Any
HTTPRequest
object may override the header_reader attribute to customize the handling of incoming headers.The server module also presents a provisional implementation of a

that will exclude any headers containing an underscore. It remains an exercise for the implementer to demonstrate how this functionality might be employed in a server such as CherryPy.:pr:`26`: Configured TravisCI to run tests under OS X.
