Small description
Yesterday I installed an old version of vd with a very outdated version of pip. I don't remember the original version number, but it wasn't version 3. The interface and plugin list matched the tutorial screenshots.
Today, I updated pip and installed the latest version of VisiData, v3.0.2.
I'm not at liberty to share the full dataset, but I can share a single screen of it below.
Expected result
The cmdlog should have executed completely within a few seconds.
Actual result with screenshot
The "select rows matching current cell in column" commands took a very long time to execute. For the commands executed in the screenshot below, the first several commands took around 6 seconds, and the final "select" command took 91 seconds to complete.
The cell was a Python error cell for a calculated column. I was selecting all cells with errors in order to determine the most common sources of errors.
Steps to reproduce with sample data and a .vd
The following sample dataset and cmdlog are sufficient to reproduce the issue.
The more I think about it, the less sure I am that the revision number wasn't 2 instead of 1. In any case, I followed the tutorial with it, and both the overall interface and pre-packaged plugin list matched whatever version was in the tutorial screenshots.
