With CLIENT_KNOBS->TOO_MANY in snapTest, by the time getRange
gathers all the results, the storage server's oldest version has
gone past the req->version and hence the transaction fails with
transaction_too_old
- remove partially snapped directories to avoid no cluster file assert
- snap create to retry max 3 times for not_fully_recovered and keep
retrying for the other failures
- wait for snapTLogFailKeys in a loop, otherwise in some race
condition it can cause a false assert
- in single region, there does not seem to be a guarantee of
tagLocalityListKey for a given DC ID, avoiding that assert for now
- to find the workers that are coordinators, looking up by primary
address is not sufficient in some cases, hence looking by both
primary and secondary address
- test make files to reflect the location of the new test cases
Earlier the test was checking for the following condition:
durable version of storage > min version of tlog, but the
check has been modified to:
durable version of storage >= min version of tlog - 1.
Ensure that the pre-snap validate keys are exactly 1000 in
the case of commit retires.
In Tlogs, disable pop is done whlie taking snapshots. Earlier, tlogs
were ignoring the pops if it got pop requests when pops were
disabled. In this change, instead of ignoring the pop - it remembers
the list of pops in-memory and plays them once the popping is
enabled.
- exec operation to go to all the TLogs
- minor bug fix in tlog
- restore implementation for the simulator
- restore snap UID to be stored in restartInfo.ini
- test cases added
- indentation and trace file fixes
