calpa/urusai v1.1.0 on GitHub

What's New

Features

Concurrent crawling — Multiply noise output with configurable concurrent workers (default: 3). Shared state protected by mutex. ([#10])
Graceful shutdown — SIGINT/SIGTERM propagates through all goroutines via context.Context. In-flight HTTP requests are cancelled cleanly. ([#8])
SSRF protection — Blocks requests to loopback, RFC1918, link-local, and IPv6 ULA addresses. Redirects limited to 5 hops. ([#13])

Bug Fixes

Recursive crawl → iterative loop — Eliminates stack overflow risk from unbounded recursion in browseFromLinks with max_depth: 25. ([#7])
Config validation — Invalid config (empty root URLs, invalid sleep range) now fails fast with descriptive error messages. ([#9])
Timeout flag override — CLI --timeout no longer silently overrides config when unset. ([#9])
Response body truncation — Single Read(buf) replaced with io.ReadAll(io.LimitReader) to capture full response up to 1 MB. ([#12])
Regex recompilation — regexp.MustCompile moved to package-level vars — compiled once, not on every call. ([#12])

Miscellaneous

Code quality sweep — Migrated to math/rand/v2, blacklist O(n) → O(1) via map, updated user agents to 2025-era, added --version flag with ldflags injection. ([#11])
Module import paths — Fixed to use github.com/calpa/urusai consistently.
