<h3 dir="auto">Apache Airflow version</h3>
<p dir="auto">2.3.3 (latest released)</p>
<h3 dir="auto">What happened</h3>
<p dir="auto">Testing airflow docker installation, checking correct dir mapping by copying one of the default dags into the <code class="notranslate">./dags</code> folder.<br>
The new dag is not added as a duplicate because duplication is detected, but the addition fails silently in the web UI while in command line tool the error <code class="notranslate">Error: Failed to load all files. For details, run airflow dags list-import-errors</code> is presented.</p>
<h3 dir="auto">What you think should happen instead</h3>
<p dir="auto">As the cli warns about the error, the web UI should warn about the duplication occurence.</p>
<h3 dir="auto">How to reproduce</h3>
<p dir="auto">Copy a default dag into the mapped <code class="notranslate">./dags</code> of a docker-compose install.</p>
<h3 dir="auto">Operating System</h3>
<p dir="auto">manjaro linux</p>

<h3 dir="auto">Apache Airflow version</h3>
<p dir="auto">2.5.3</p>
<h3 dir="auto">What happened</h3>
<p dir="auto">I upgraded my airflow cluster from 2.5.2 to 2.5.3 , after which strange things started happening.<br>
I'm currently using a standalone dagProcessor, and the parsing time that used to take about 2 seconds has suddenly increased to about 10 seconds.<br>
I'm thinking it's weird because I haven't made any changes other than a version up, but is there something I can look into? Thanks in advance! 🙇🏼<br>

<h3 dir="auto">What you think should happen instead</h3>
<p dir="auto">I believe that the time it takes to parse a Dag should be constant, or at least have some variability, but shouldn't take as long as it does now.</p>
<h3 dir="auto">How to reproduce</h3>
<p dir="auto">If you cherrypick <a href="https://github.com/apache/airflow/pull/30079" data-hovercard-type="pull_request" data-hovercard-url="/apache/airflow/pull/30079/hovercard">this commit</a> into 2.5.2 stable code, the issue will recur.</p>
