From 7139e28b4e2e14b6e16b3277f2c64b270038dc2e Mon Sep 17 00:00:00 2001 From: aitbc Date: Thu, 14 May 2026 23:56:14 +0200 Subject: [PATCH] fix: IPFS integration improvements - Fix IPFS storage service: handle session=True response format (CID string vs dict) - Fix metadata cache: use in-memory dict instead of no-op pass - Fix IPFS router: use singleton pattern for service instance - Fix IPFS cat: use POST method instead of GET - Add _metadata_cache initialization to IPFSStorageService - Coordinator IPFS upload/retrieve now fully functional with integrity verification --- apps/blockchain-node/src/aitbc_chain/app.py | 23 +++++++++++----- apps/blockchain-node/src/aitbc_chain/main.py | 25 ++++++++++++++++++ .../src/app/contexts/ipfs/routers/ipfs.py | 26 ++++++++++--------- .../src/app/services/ipfs_storage_service.py | 22 ++++------------ 4 files changed, 60 insertions(+), 36 deletions(-) diff --git a/apps/blockchain-node/src/aitbc_chain/app.py b/apps/blockchain-node/src/aitbc_chain/app.py index 7fd6432d..0313e946 100755 --- a/apps/blockchain-node/src/aitbc_chain/app.py +++ b/apps/blockchain-node/src/aitbc_chain/app.py @@ -100,6 +100,7 @@ class RequestLoggingMiddleware(BaseHTTPMiddleware): @asynccontextmanager async def lifespan(app: FastAPI): + _app_logger.info("Lifespan function started") init_db() init_mempool( backend=settings.mempool_backend, @@ -112,13 +113,21 @@ async def lifespan(app: FastAPI): _app_logger.info("Gossip backend initialized successfully") # Initialize island manager for edge API support -
