Working version of a fix for #826

We deduplicate linecache entries, thus avoiding identical class creation time increasing linearly and saving memory in the process.

Sure, put this into a01.py:

import attr


def create_class():
    @attr.s
    class MyClass(object):
        access_token = attr.ib()
        expires = attr.ib()
        refresh_token = attr.ib()
        user = attr.ib()

Then, on master:

> pyperf timeit -g -s "from a01 import create_class" "create_class()"

Well, it's O(1), right? That sounds good enough to me.

@euresti @MRSAGE – any feelings?

I noticed that _make_hash does this:

    unique_filename = _generate_unique_filename(cls, "hash")
    type_hash = hash(unique_filename)
    ...

Does the fact that type_hash is no longer unique matter? I don't think it does but I figure better to ask.

Good question. Given two identical classes, equal instances will now hash the same. They will still not compare the same, I believe, so the contract is preserved. Not sure if this affects anything in the real world though. Maybe makes dicts and sets of identical classes a tiny bit less efficient?

I love this fix. Ship it!

This definitely gets rid of the surprise factors, I am still curious if the use of linecache is needed at all though. But the main concern is taken care of, certainly!

You mean in general? It’s so you can step through the generated methods with pdb.

465: build(deps): bump attrs from 21.2.0 to 21.3.0 r=ChrisRBe a=dependabot[bot]

Bumps [attrs](https://github.com/python-attrs/attrs) from 21.2.0 to 21.3.0.
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a href="https://github.com/python-attrs/attrs/releases">attrs's releases</a>.</em></p>
<blockquote>
<h2>21.3.0</h2>
<p>This is a big release in the history of <code>attrs</code> and finishes an arc that took way too long and also delayed this very overdue release. But it's done: <code>import attrs</code> that has been talked about for years[^issue], but fell victim to “just this one more thing” has <em>finally</em> landed.</p>
<p>From now on, modern <code>attrs</code> code looks like this:</p>
<pre lang="python"><code>from attrs import define
<p><a href="https://github.com/define"><code>`@​define</code></a>`
class HelloWorld:
modern: bool = True
</code></pre></p>
<p>The <code>define</code>/<code>field</code> APIs have been around for over a year and were very popular, now the rest of the package followed suit. I'm very excited that <code>attrs</code> remains relevant and keeps evolving over now more than half a decade. If you're curious about some of the background, the docs now contain a short <a href="https://www.attrs.org/en/stable/names.html">explanation and history lesson</a>. As long as our users keep pushing us, we will keep pushing forward class generation in Python!</p>
<p>Big thanks to my <a href="https://github.com/sponsors/hynek/dashboard">GitHub Sponsors</a>, <a href="https://tidelift.com/subscription/pkg/pypi-attrs?utm_source=pypi-attrs&amp;utm_medium=referral&amp;utm_campaign=enterprise&amp;utm_term=repo">Tidelift subscribers</a>, and <a href="https://ko-fi.com/the_hynekl">Ko-fi buyers</a> that help me mustering the motivation for such long-running project!</p>
<hr />
<p>Since the release took so long, there's more highlights than we can enumerate here, we'd just like to point out a breaking change in the new APIs: converters now run on setting attributes by default. If this is causing problems to you, you can disable that behavior by setting <code>`@define(on_setattr=[])</code>.</p>`
<p>[^issue]:  I have an issue from 2018 that I wanted to &quot;come back the moment this lands&quot;.</p>
<h1>Full Changelog</h1>
<h2>Backward-incompatible Changes</h2>
<ul>
<li>
<p>When using <code>`@define</code>,` converters are now run by default when setting an attribute on an instance -- additionally to validators. I.e. the new default is <code>on_setattr=[attrs.setters.convert, attrs.setters.validate]</code>.</p>
<p>This is unfortunately a breaking change, but it was an oversight, impossible to raise a <code>DeprecationWarning</code> about, and it's better to fix it now while the APIs are very fresh with few users. <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/835">#835</a>, <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/886">#886</a></p>
</li>
<li>
<p><code>import attrs</code> has finally landed! As of this release, you can finally import <code>attrs</code> using its proper name.</p>
<p>Not all names from the <code>attr</code> namespace have been transferred; most notably <code>attr.s</code> and <code>attr.ib</code> are missing. See <code>attrs.define</code> and <code>attrs.field</code> if you haven't seen our next-generation APIs yet. A more elaborate explanation can be found <a href="https://www.attrs.org/en/latest/names.html">On The Core API Names</a></p>
<p>This feature is at least for one release <strong>provisional</strong>. We don't <em>plan</em> on changing anything, but such a big change is unlikely to go perfectly on the first strike.</p>
<p>The API docs have been mostly updated, but it will be an ongoing effort to change everything to the new APIs. Please note that we have <strong>not</strong> moved -- or even removed -- anything from <code>attr</code>!</p>
<p>Please do report any bugs or documentation inconsistencies! <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/887">#887</a></p>

<blockquote>
<h2>21.3.0</h2>
<p>This is a big release in the history of <code>attrs</code> and finishes an arc that took way too long and also delayed this very overdue release. But it's done: <code>import attrs</code> that has been talked about for years[^issue], but fell victim to “just this one more thing” has <em>finally</em> landed.</p>
<p>From now on, modern <code>attrs</code> code looks like this:</p>
<pre lang="python"><code>from attrs import define
<p><a href="https://github.com/define"><code>`@​define</code></a>`
class HelloWorld:
modern: bool = True
</code></pre></p>
<p>The <code>define</code>/<code>field</code> APIs have been around for over a year and were very popular, now the rest of the package followed suit. I'm very excited that <code>attrs</code> remains relevant and keeps evolving over now more than half a decade. If you're curious about some of the background, the docs now contain a short <a href="https://www.attrs.org/en/stable/names.html">explanation and history lesson</a>. As long as our users keep pushing us, we will keep pushing forward class generation in Python!</p>
<p>Big thanks to my <a href="https://github.com/sponsors/hynek/dashboard">GitHub Sponsors</a>, <a href="https://tidelift.com/subscription/pkg/pypi-attrs?utm_source=pypi-attrs&amp;utm_medium=referral&amp;utm_campaign=enterprise&amp;utm_term=repo">Tidelift subscribers</a>, and <a href="https://ko-fi.com/the_hynekl">Ko-fi buyers</a> that help me mustering the motivation for such long-running project!</p>
<hr />
<p>Since the release took so long, there's more highlights than we can enumerate here, we'd just like to point out a breaking change in the new APIs: converters now run on setting attributes by default. If this is causing problems to you, you can disable that behavior by setting <code>`@define(on_setattr=[])</code>.</p>`
<p>[^issue]:  I have an issue from 2018 that I wanted to &quot;come back the moment this lands&quot;.</p>
<h1>Full Changelog</h1>
<h2>Backward-incompatible Changes</h2>
<ul>
<li>
<p>When using <code>`@define</code>,` converters are now run by default when setting an attribute on an instance -- additionally to validators. I.e. the new default is <code>on_setattr=[attrs.setters.convert, attrs.setters.validate]</code>.</p>
<p>This is unfortunately a breaking change, but it was an oversight, impossible to raise a <code>DeprecationWarning</code> about, and it's better to fix it now while the APIs are very fresh with few users. <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/835">#835</a>, <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/886">#886</a></p>
</li>
<li>
<p><code>import attrs</code> has finally landed! As of this release, you can finally import <code>attrs</code> using its proper name.</p>
<p>Not all names from the <code>attr</code> namespace have been transferred; most notably <code>attr.s</code> and <code>attr.ib</code> are missing. See <code>attrs.define</code> and <code>attrs.field</code> if you haven't seen our next-generation APIs yet.

<h2>21.3.0 (2021-12-28)</h2>
<p>Backward-incompatible Changes
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^</p>
<ul>
<li>
<p>When using <code>@define</code>, converters are now run by default when setting an attribute on an instance -- additionally to validators.
I.e. the new default is <code>on_setattr=[attrs.setters.convert, attrs.setters.validate]</code>.</p>
<p>This is unfortunately a breaking change, but it was an oversight, impossible to raise a <code>DeprecationWarning</code> about, and it's better to fix it now while the APIs are very fresh with few users.

<p><em>Sourced from <a href="https://github.com/python-attrs/attrs/releases">attrs's releases</a>.</em></p>
<blockquote>
<h2>21.3.0</h2>
<p>This is a big release in the history of <code>attrs</code> and finishes an arc that took way too long and also delayed this very overdue release. But it's done: <code>import attrs</code> that has been talked about for years[^issue], but fell victim to “just this one more thing” has <em>finally</em> landed.</p>
<p>From now on, modern <code>attrs</code> code looks like this:</p>
<pre lang="python"><code>from attrs import define
<p><a href="https://github.com/define"><code>`@​define</code></a>`
class HelloWorld:
modern: bool = True
</code></pre></p>
<p>The <code>define</code>/<code>field</code> APIs have been around for over a year and were very popular, now the rest of the package followed suit. I'm very excited that <code>attrs</code> remains relevant and keeps evolving over now more than half a decade. If you're curious about some of the background, the docs now contain a short <a href="https://www.attrs.org/en/stable/names.html">explanation and history lesson</a>. As long as our users keep pushing us, we will keep pushing forward class generation in Python!</p>
<p>Big thanks to my <a href="https://github.com/sponsors/hynek/dashboard">GitHub Sponsors</a>, <a href="https://tidelift.com/subscription/pkg/pypi-attrs?utm_source=pypi-attrs&amp;utm_medium=referral&amp;utm_campaign=enterprise&amp;utm_term=repo">Tidelift subscribers</a>, and <a href="https://ko-fi.com/the_hynekl">Ko-fi buyers</a> that help me mustering the motivation for such long-running project!</p>
<hr />
<p>Since the release took so long, there's more highlights than we can enumerate here, we'd just like to point out a breaking change in the new APIs: converters now run on setting attributes by default. If this is causing problems to you, you can disable that behavior by setting <code>`@define(on_setattr=[])</code>.</p>`
<p>[^issue]:  I have an issue from 2018 that I wanted to &quot;come back the moment this lands&quot;.</p>

465: build(deps): bump attrs from 21.2.0 to 21.3.0 r=ChrisRBe a=dependabot[bot]

<summary>Release notes</summary>
<p><em>Sourced from <a href="https://github.com/python-attrs/attrs/releases">attrs's releases</a>.</em></p>
<blockquote>
<h2>21.3.0</h2>
<p>This is a big release in the history of <code>attrs</code> and finishes an arc that took way too long and also delayed this very overdue release. But it's done: <code>import attrs</code> that has been talked about for years[^issue], but fell victim to “just this one more thing” has <em>finally</em> landed.</p>
<p>From now on, modern <code>attrs</code> code looks like this:</p>
<pre lang="python"><code>from attrs import define
<p><a href="https://github.com/define"><code>`@​define</code></a>`
class HelloWorld:
modern: bool = True
</code></pre></p>
<p>The <code>define</code>/<code>field</code> APIs have been around for over a year and were very popular, now the rest of the package followed suit. I'm very excited that <code>attrs</code> remains relevant and keeps evolving over now more than half a decade. If you're curious about some of the background, the docs now contain a short <a href="https://www.attrs.org/en/stable/names.html">explanation and history lesson</a>. As long as our users keep pushing us, we will keep pushing forward class generation in Python!</p>
<p>Big thanks to my <a href="https://github.com/sponsors/hynek/dashboard">GitHub Sponsors</a>, <a href="https://tidelift.com/subscription/pkg/pypi-attrs?utm_source=pypi-attrs&amp;utm_medium=referral&amp;utm_campaign=enterprise&amp;utm_term=repo">Tidelift subscribers</a>, and <a href="https://ko-fi.com/the_hynekl">Ko-fi buyers</a> that help me mustering the motivation for such long-running project!</p>
<hr />
<p>Since the release took so long, there's more highlights than we can enumerate here, we'd just like to point out a breaking change in the new APIs: converters now run on setting attributes by default. If this is causing problems to you, you can disable that behavior by setting <code>`@define(on_setattr=[])</code>.</p>`
<p>[^issue]:  I have an issue from 2018 that I wanted to &quot;come back the moment this lands&quot;.</p>
<h1>Full Changelog</h1>
<h2>Backward-incompatible Changes</h2>
<ul>
<li>
<p>When using <code>`@define</code>,` converters are now run by default when setting an attribute on an instance -- additionally to validators. I.e. the new default is <code>on_setattr=[attrs.setters.convert, attrs.setters.validate]</code>.</p>
<p>This is unfortunately a breaking change, but it was an oversight, impossible to raise a <code>DeprecationWarning</code> about, and it's better to fix it now while the APIs are very fresh with few users. <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/835">#835</a>, <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/886">#886</a></p>
</li>
<li>
<p><code>import attrs</code> has finally landed! As of this release, you can finally import <code>attrs</code> using its proper name.</p>
<p>Not all names from the <code>attr</code> namespace have been transferred; most notably <code>attr.s</code> and <code>attr.ib</code> are missing. See <code>attrs.define</code> and <code>attrs.field</code> if you haven't seen our next-generation APIs yet. A more elaborate explanation can be found <a href="https://www.attrs.org/en/latest/names.html">On The Core API Names</a></p>
<p>This feature is at least for one release <strong>provisional</strong>. We don't <em>plan</em> on changing anything, but such a big change is unlikely to go perfectly on the first strike.</p>
<p>The API docs have been mostly updated, but it will be an ongoing effort to change everything to the new APIs. Please note that we have <strong>not</strong> moved -- or even removed -- anything from <code>attr</code>!</p>
<p>Please do report any bugs or documentation inconsistencies! <a href="https://github-redirect.dependabot.com/python-attrs/attrs/issues/887">#887</a></p>
