RaresKeYandLéo d449a9d431 fix(history): defer full transcript hydration to model sends (#5929)
* fix(history): defer full hydration to model sends

* fix(session): key hydration on real rows, fork through get_session

Two regressions from the display/model-context split, both reproducible
against dev.

The hydration gate compared the cached transcript against the
denormalized sessions.message_count column. That column drifts in normal
operation — _persist_message swallows a failed insert while add_message
has already appended in memory, so the next successful persist writes
rows+1 — and _db_to_session re-read the same column after each reload, so
the shortfall never closed. Every send, edit, delete and truncate on a
warm session re-selected the whole message table: the cost this change
set out to remove, relocated onto the hot path. The other direction was
just as bad — a persist for an uncached session writes message_count = 0,
and a stale-low counter with a partly filled cache meant no hydration at
all and a silently truncated transcript for the model.

sync_session_metadata now reconciles message_count against COUNT(*) on
chat_messages (one indexed count inside the connection it already opens),
and _db_to_session trusts the rows it just loaded. A hydrate always
closes the gap, so the next read is a cache hit.

fork_session read session_manager.sessions directly and never hydrated.
keep_count indexes into source.history, and display pagination no longer
fills that cache, so forking after a restart returned HTTP 200 with an
empty conversation and no error surfaced. It goes through get_session
now.

_hydrate_session_history_from_db is gone with its helper: get_session is
the hydration seam, and rebuilding session.history from raw rows in the
display fallback overwrote the parsed multimodal content and the _db_id
edit/delete keys that had just been set.

Tests drive a real SessionManager over a temp DB instead of a stub that
only proved the stub hydrates — both drift directions, the send path
warm and cold, and a fork taken after a restart. All five fail without
this change. The brittle SQL-text assertions are dropped; the page
bounds are already proven by the response body.

* fix(history): route pagination through canonical handler

Quick Start

dev is the default branch and gets the newest changes first. Use main if you want the more curated branch.

git clone https://github.com/odysseus-dev/odysseus.git
cd odysseus
cp .env.example .env
docker compose up -d --build

Open http://localhost:7000 when the containers are healthy. The first admin password is printed in docker compose logs odysseus.

Native installs, GPU notes, Windows/macOS instructions, HTTPS, and configuration live in the setup guide.

Features

  • Chat + Agents — local/API models, tools, MCP, files, shell, skills, and memory.
  • Cookbook — hardware-aware model recommendations, downloads, and serving.
  • Deep Research — multi-step web research with source reading and report generation.
  • Compare — blind side-by-side model testing and synthesis.
  • Documents — writing-first editor with AI edits, suggestions, Markdown, HTML, CSV, and syntax highlighting.
  • Email — IMAP/SMTP inbox with triage, tags, summaries, reminders, and reply drafts.
  • Notes, Tasks + Calendar — reminders, todos, scheduled agent tasks, and CalDAV sync.
  • Extras — gallery/image editor, themes, uploads, web search, presets, sessions, and 2FA.

Demo

A full hover-to-play tour lives on the landing page: docs/index.html.

Contributing

Help is welcome. The best entry points are fresh-install testing, provider setup bugs, mobile/editor polish, docs, and small focused refactors. See CONTRIBUTING.md and ROADMAP.md.

Security

Odysseus is a self-hosted workspace with powerful local tools. Keep auth enabled, keep private data out of Git, and do not expose raw model/service ports publicly. Deployment details are in the setup guide.
