Changes

fix cyclic garbage that keeps traceback frames alive in taskgroup exceptions

This reproduces the behaviour in trio (the trio versions of the test pass with minor modifications of the anyio wrappers). Producing cyclic garbage is not usually a problem, however when an exception traceback references that exception again the entire traceback and therefore all frames in the stack remain alive until the garbage collector runs.

Checklist

If this is a user-facing code change, like a bugfix or a new feature, please ensure that
you've fulfilled the following conditions (where applicable):

  • You've added tests (in tests/) added which would fail without your patch
  • You've updated the documentation (in docs/, in case of behavior changes or new
    features)
  • You've added a new changelog entry (in docs/versionhistory.rst).

If this is a trivial change, like a typo fix or a code reformatting, then you can ignore
these instructions.

Updating the changelog

If there are no entries after the last release, use **UNRELEASED** as the version.
If, say, your patch fixes issue #123, the entry should look like this:

* Fix big bad boo-boo in task groups (#123 <https://github.com/agronholm/anyio/issues/123>_; PR by @yourgithubaccount)

If there's no issue linked, just link to your pull request instead by updating the
changelog after you've created the PR.

<h1>Version history</h1>

<p><strong>4.6.2</strong></p>
<ul>
<li>Fixed regression caused by
(<code>[#807](agronholm/anyio#807)
&lt;https://github.com/agronholm/anyio/pull/807&gt;</code>_)
that prevented the use of parametrized async fixtures</li>

<p><strong>4.6.1</strong></p>
<p>This release contains all the changes from both v4.5.1 and v4.6.0,
plus:</p>
<ul>
<li>Fixed TaskGroup and CancelScope producing cyclic references in
tracebacks
when raising exceptions
(<code>[#806](agronholm/anyio#806)

(PR by <a

</ul>
<p><strong>4.6.0</strong></p>
<p>This release is the successor to v4.5.0 with Python 3.8 support
dropped, and does not
contain the changes from v4.5.1.</p>
<ul>
<li>Dropped support for Python 3.8
(as <code>[#698](agronholm/anyio#698)
&lt;https://github.com/agronholm/anyio/issues/698&gt;</code>_ cannot be
resolved
without cancel message support)</li>
<li>Fixed 100% CPU use on asyncio while waiting for an exiting task
group to finish while
said task group is within a cancelled cancel scope
(<code>[#695](agronholm/anyio#695)
&lt;https://github.com/agronholm/anyio/issues/695&gt;</code>_)</li>
<li>Fixed cancel scopes on asyncio not propagating
<code>CancelledError</code> on exit when the
enclosing cancel scope has been effectively cancelled
(<code>[#698](agronholm/anyio#698)
&lt;https://github.com/agronholm/anyio/issues/698&gt;</code>_)</li>
<li>Fixed asyncio task groups not yielding control to the event loop at
exit if there were
no child tasks to wait on</li>
<li>Fixed inconsistent task uncancellation with asyncio cancel scopes
belonging to a
task group when said task group has child tasks running</li>
</ul>
<p><strong>4.5.1</strong></p>
<p>As Python 3.8 support was dropped in v4.6.0, this interim release was
created to bring a
regression fix to Python 3.8, and adds a few other fixes also present in
v4.6.1.</p>
<ul>
<li>Fixed acquring a lock twice in the same task on asyncio hanging
instead of raising a
<code>RuntimeError</code>
(<code>[#798](agronholm/anyio#798)
&lt;https://github.com/agronholm/anyio/issues/798&gt;</code>_)</li>
<li>Fixed an async fixture's <code>self</code> being different than the
test's <code>self</code> in
class-based tests
(<code>[#633](agronholm/anyio#633)
&lt;https://github.com/agronholm/anyio/issues/633&gt;</code>_)
(PR by <a
href="https://github.com/agronholm"><code>@​agronholm</code></a> and <a
href="https://github.com/graingert"><code>@​graingert</code></a>)</li>
<li>Fixed <code>TypeError</code> with <code>TLSStream</code> on Windows
when a certificate verification
error occurs when using a <code>truststore
