Hello,
Here is a new rebased version of the full patch set for orphaned file
cleanup. The orphaned file cleanup code itself hasn't changed but
there are some changes in lower down patches:
* getting rid of more global variables, instead using eg
CurrentSession->attached_undo_logs (the session.h infrastructure that
is intended to avoid creating more multithreading-hostile code)
* using undo log "slots" in various APIs to make it clearer that slots
can be recycled, which has locking implications, plus several locking
bug fixes that motivated that change
* current versions of the record and worker code discussed upthread by
Amit and others
The code is also at https://github.com/EnterpriseDB/zheap/tree/undo
and includes patches from
https://github.com/EnterpriseDB/zheap/tree/undoprocessing and
https://github.com/EnterpriseDB/zheap/tree/undo_interface_v1 where
some parts of this stack (workers etc) are being developed.
