- New temp_storage.py module stores files on disk instead of in-memory - Multiple Gunicorn workers can now share temp files - Startup cleanup removes leftover files from previous runs - Dockerfile creates temp_files directory - Added temp_files/ to .gitignore Previously encode preview worked but download failed with "File expired" because each worker had its own in-memory TEMP_FILES dict. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

# Stegasoo Docker Image
|
|
# Uses pre-built base image for fast rebuilds
|
|
#
|
|
# First time setup:
|
|
# docker build -f Dockerfile.base -t stegasoo-base:latest .
|
|
#
|
|
# Then build normally (fast!):
|
|
# docker-compose build
|
|
#
|
|
# Or if you don't have the base image, this falls back to building deps
|
|
# (slow, but works)
|
|
|
|
# ============================================================================
|
|
# ARG to switch between base image and full build
|
|
# ============================================================================
|
|
ARG USE_BASE_IMAGE=true
|
|
|
|
# ============================================================================
|
|
# Base stage - use pre-built image if available
