-Subject: [PATCH] Fix deadlock with storages that "sync" on a new transaction
-
-This backports a change from commit 227953b977a9e195c4ce9bbb9acd9c5ee60c333a.
-
-NEO, as well as ZEO+server_sync (ERP5 backports this feature with a
-monkey-patch), pings the server (primary master node in the case of NEO) on
-new transactions. However, this round-trip is actually performed by the thread
-that also does tasks requiring to lock the DB, like processing of invalidations.
-
-Since transaction 1.6.1 (more precisely commit e581a120a6), IStorage.sync()
-is called indirectly by DB.open() when a transaction has already begun,
-and the DB must not be locked when this happens.
