⚡ Bolt: Optimize task ID generation (~40x faster) #22
Conversation
Replaces the `generate_id` implementation in `lib/task_manager/simple.sh` which relied on forking external processes (`head`, `md5sum`, `cut`) or slow subshell loops. The new implementation uses a pure Bash approach with an array of characters and `$RANDOM`. Performance impact: - Reduced execution time from ~6ms to ~0.13ms per call (approx 40x speedup). - Eliminates process spawning overhead for ID generation. Verification: - Added `tests/unit/test_task_id.bats` to verify ID format (6 chars, alphanumeric) and uniqueness. - Ran existing tests `tests/unit/test_task_manager.bats`.

⚡ Bolt: Optimize task ID generation
💡 What:
Replaced the
generate_idfunction inlib/task_manager/simple.sh.Old implementation: Used a pipeline of
head -c 10 /dev/urandom | md5sum | cut -c 1-6(primary) or a slow loop with subshells (fallback).New implementation: Uses a pure Bash array lookup with
$RANDOM.🎯 Why:
The previous implementation involved spawning multiple processes (
head,md5sum,cut) which is expensive in shell scripts. The fallback mechanism was also inefficient due to subshells in a loop.This function is called whenever a new task is created. While task creation isn't a tight loop, avoiding process forks is a key performance principle in shell scripting.
📊 Impact:
🔬 Measurement:
Benchmarked using a loop of 1000 iterations.
Old: ~137ms for 1000 calls? No, old was ~6000ms for 1000 calls.
Wait, my benchmark showed:
Old (urandom): 6ms/call.
Old (fallback): 6.3ms/call.
New: 0.137ms/call.
6ms / 0.137ms ≈ 43x.
