Juhani Ränkimies commented on COUCHDB-86:
-----------------------------------------
Once I get my erlang build env set up, I'd like to try moving the 'swap'
operation to couch_file process that has the descriptor for the active file.
There it would be possible to explicitly close the active file before renaming.
> (CouchDB on Windows) compaction can not be done.

> Project: CouchDB
> Issue Type: Bug
> Components: Build System
> Affects Versions: 0.8
> Environment: Windows XP, Erlang/OTP R12B-3
> Reporter: Li Zhengji

> During compacting, rename the current DB file to a .old file is not allowed
> on Windows.
> A possible workaround for this could be:
> 1. Close current DB file (.couch);
> 2. Send db_updated to update to use .compact;
> 3. After 5sec, delete the .couch file; ---- This is done in a linked
> process, after that, this process send a message to update_loop;
> 4. After received the message in update_loop, close current DB file which is
> a .compact file, then rename it to .couch;
> 5. Finally, db_updated again to use this new .couch file.
> Maybe, there would be a "pause" in service?
