ChemaVXandClaude Fable 5 ae56227c03 fix(scraper): endurecer memoria — PDF cap 15MB en executor, contenido cap 300k chars
Un batch de 20 fuentes concurrentes con un documento de 98k palabras y
varios PDFs grandes mató el pod (OOMKilled, límite 1Gi) el 2026-07-10 en
plena investigación.

- _extract_pdf: cap bajado de 50MB a 15MB, verificado también sobre el
  body real (Content-Length puede faltar); pdfplumber movido a
  run_in_executor (es síncrono y congelaba el event loop, misma clase de
  bug que DDGS) con flush_cache() por página.
- _mark_scraped: contenido truncado a settings.max_content_length
  (300k chars) antes de guardarlo en source_contents — libros enteros
  inflan RAM y DB sin aportar al RAG.

🦉 ResearchOwl

Exhaustive research engine with Telegram interface.

Recursively discovers, scrapes, and processes sources from across the web, then generates podcast scripts, blog posts, reports, or social threads using Ollama.

Architecture

Telegram (/research <topic>)

Telegram Commands

Command Description
/research <topic> Start exhaustive research
/status Check progress
/finish Stop early, proceed to generation
/generate podcast|blog|report|thread Generate output
/sources List all sources found
/cancel Cancel current research

Local Development

# 1. Clone and setup
git clone https://git.chemavx.xyz/chemavx/researchowl
cd researchowl

# 2. Create virtualenv
python3 -m venv venv && source venv/bin/activate
pip install -r requirements.txt

# 3. Configure
cp .env.example .env
# Edit .env with your values

# 4. Run
python main.py

Deploy to k3s

# 1. Create namespace and secrets
kubectl create namespace researchowl
kubectl create secret generic researchowl-secrets \
  --from-literal=telegram-bot-token=YOUR_TOKEN \
  --from-literal=telegram-allowed-users=YOUR_USER_ID \
  -n researchowl

# 2. Copy manifests to your k8s-manifests repo
cp k8s/*.yaml /path/to/k8s-manifests/researchowl/

# 3. Apply ArgoCD app
kubectl apply -f k8s/argocd-app.yaml

# 4. Push to Gitea → Gitea Actions builds → ArgoCD deploys
git add . && git commit -m "feat: add researchowl" && git push

Tuning

Variable Default Description
MAX_SOURCES 150 Hard cap on sources
MAX_DEPTH 3 Link recursion depth
QUALITY_THRESHOLD 0.4 Min chunk quality (0-1)
REQUEST_DELAY 1.0s Delay between requests

Want more thoroughness?

  • Increase MAX_SOURCES to 300+
  • Increase MAX_DEPTH to 4-5
  • Lower QUALITY_THRESHOLD to 0.3

Want faster results?

  • Lower MAX_SOURCES to 50
  • Set MAX_DEPTH to 1-2
  • Higher QUALITY_THRESHOLD to 0.6

Notes

  • Uses qwen2.5:3b (your existing Ollama) for all AI tasks — zero API cost
  • Optionally add ANTHROPIC_API_KEY for Claude fallback on generation
  • SQLite database stored in /data/researchowl.db
  • All outputs saved to DB and available via /outputs
