[Rpm-maint] [rpm-software-management/rpm] Rpm query causes corruption in the file-backed mmaped bdb regions (#232)

[Jeff Johnson]

After looking at current rpm.org sources, RPM still initializes with ts->dbmode = DB_RDONLY, and then  reopens the rpmdb with O_RW in rpmtsSetup(). That opens a (minor and mostly irrelevant wrto RPM on OS X) race window.

There is still the ability to disable fsync (or replace with fdatasync) within RPM sources. I would verify what setting you are using with RPM on OS X. What "works" on linux, may not work on OS X.

BTW, what version of Berkeley DB are you using on OS X?
