f57a54a301 mdbx: fix mtest1 for backlog-autosync. 
After the ae324984cb steady
checkpoint(s) could be created automatically while reserve a
pages for deletion from freeDB.

In other words, some (beginning of list) of modify-ops were
"unexpectedly" synced to disk, despite of the no-sync closing
of DB by the mtest1 - therefore testcase could fail.

Now required rollback at least one of transactions after the
last explicit sync, but not all of ones.

2016-03-30 19:46 GMT+03:00 Howard Chu <hyc@symas.com>:

That logic is backwards because I was preserving existing behavior,
i.e. make the page - including unused portions - look the same with
put() in the child txn as put() in the parent.  So with MDB_RESERVE
the entire page must be copied in case the user peeks at it before
writing to it.  Without MDB_RESERVE, the initial part of the page
body need not be copied since LMDB is about to overwrite it.

I'll comment that, unless that code should just go away.  Don't know
if this is the best behavior or it was just easier to code it than
to decide whether to cater to such obscure user behavior.  But
people do come up with special things do do about overflow pages.
