feat(my-deepagent): v0.3 PR #1 — interactive session persistence + LangGraph saver wiring
v0.3의 토대. REPL/GUI 둘 다 장기 대화를 영속해서 `mydeepagent --session <id>`
또는 `GET /api/sessions/{id}`로 어디서든 이어 진행 가능. Claude Code의
`claude --resume` 등가 능력.
Data model
- `persistence/models.py`:
- 신규 `MessageRow` 테이블 — (session_id, seq) UNIQUE, role/content/
tool_calls/token_count/is_summary/archived/ts. LangGraph checkpoint =
source of truth, 이 테이블은 GUI/CLI 빠른 조회 mirror. divergence
rebuild 매커니즘 없음 (단순성 우선).
- `InteractiveSessionRow` 컬럼 8개 추가:
total_input_tokens, total_output_tokens (PR #2 tiktoken으로 정밀화 예정),
model, project_key (sha256(realpath(repo_path))[:16]),
title (첫 user msg 50자), plan_mode (PR #5), parent_session_id (PR #6),
depth (PR #6 sub-agent depth ≤ 3).
- `alembic/versions/684e70f4536a_*.py` (신규):
- `op.batch_alter_table` 사용 — SQLite ALTER constraint 미지원 우회. Postgres는
native DDL.
- 자동생성이 제안한 LangGraph 테이블 (`checkpoints` 등) drop 라인은 의도적으로
제거 (langgraph-checkpoint-postgres가 자체 관리).
- server_default 박아서 기존 row 안전.
CLI
- `cli/interactive.py`:
- REPL 진입 시 `get_checkpointer_ctx(config.database_url)` 컨텍스트 열고
REPL 전체 동안 유지. `build_agent(..., checkpointer=saver)`로 deepagents에
LangGraph saver wire. v0.2 PR #10의 CostMiddleware / AuditToolMiddleware
보존.
- `_invoke_and_stream`이 ainvoke 전후 명시적 MessageRow insert
(user → ainvoke → assistant). last_message_at + total_*_tokens 누적 +
첫 user msg로 title 자동 setter.
- `InteractiveSession.thread_suffix` 도입. /model / /agent / /clear 호출
시 suffix bump → LangGraph thread_id = `{session_id}:{suffix}` 로 새
deepagents 컨텍스트 시작 (compaction과 같은 패턴, PR #2 재사용).
- 신규 `--session <id|prefix>` 옵션: 기존 row 로드 (ended이면 거부) 또는
신규 row insert (AgentPersonaRow upsert + project_key 박음).
- `/clear` 슬래시 갱신: messages.archived=True + 새 thread 시작. 세션 자체
는 살아있음 — `sessions show <id> --all`로 조회 가능.
- `cli/sessions.py` (신규): `mydeepagent sessions list/show/resume/end`.
show <id> [--all]이 archived 메시지까지. 6+ char prefix + 중복 시 명시
에러.
- `cli/main.py`: --session 옵션 + sessions 서브명령 + interactive_command
시그니처 확장.
HTTP API
- `api/models.py`: SessionSummary / MessageInfo / SessionDetail /
CreateSessionRequest / PostMessageRequest / SessionAck DTO 신규 (모두
extra="forbid").
- `api/routes/sessions.py` (신규):
GET /api/sessions?limit=&state=
GET /api/sessions/{id}?all=true (마지막 200 메시지)
POST /api/sessions (persona_name, model_override, repo_path)
POST /api/sessions/{id}/messages (사용자 메시지 append, 동기 persist;
PR #7 GUI에서 background ainvoke 추가)
GET /api/sessions/{id}/stream (SSE — 0.5s polling, last-event-id 헤더
+ ?last_seq 둘 다 지원)
POST /api/sessions/{id}/end
- `api/app.py`: sessions 라우터 마운트.
Tests
- `tests/integration/test_session_persist.py` (5 시나리오):
1. create + post → row + 메시지 + title + token 누적 영속
2. list가 신규 3 세션 모두 포함
3. prefix resolution + 404
4. end 후 메시지 거부 (409)
5. ?all=true가 archived 메시지 surfacing

"""v0.3 PR #1 — interactive session persistence tests.
|

|
||||
5 scenarios from the plan:
|
||||
1. New session via POST /api/sessions → row + first message persists
|
||||
2. Same session re-listed (resume picker) → still active + history visible
|
||||
3. `mydeepagent sessions list` returns recent sessions in last-activity order
|
||||
4. resolve_session_id accepts 6+ char prefix uniquely; rejects ambiguity
|
||||
5. ended sessions reject further POST /messages
