() ``` The problem is in the method: PopulateBeforeImage When we drop a column, the the row won't have data for the dropped column, and hence will not be added to the "old_tuple" member of RowMessage. This will mean the size of "old_tuple" does not match the number of columns in the schema. Which means this line: "row_message->old_tuple(static_cast<int>(index))" could lead to an out of bounds exception. Instead, now we are keeping track of the found columns in the row.

Summary: YB Seq Scan code path is not hit because Foreign Scan is the default and pg hint plan does not work. Upcoming merge with YB master will bring in master commit 465ee2c which changes the default to YB Seq Scan. To test YB Seq Scan, a temporary patch is needed (see the test plan). With that, two bugs are encountered: fix them. 1. FailedAssertion("TTS_IS_VIRTUAL(slot)" On simple test case create table t (i int primary key, j int); select * from t; get TRAP: FailedAssertion("TTS_IS_VIRTUAL(slot)", File:

It appears that the function `yb::pgwrapper::LibPqTestBase::Connect` isn't
thread safe. I restructured the code to make the connections in a single thread
and then pass them to various concurrent threads for testing.

…ng the lock Summary: Call callback in ScopeExit block only. Not while holding the lock. Without this fix, it is possible that a thread can get into a deadlock, trying to request a shared_lock on a mutex, while already holding an exclusive lock on the same mutex: This deadlock can be triggered if there are active read/write requests to a Table (from more than 1 thread) right after the table had a tablet-split. If there is only 1 thread, it is unlikely to run into the deadlock, as the thread notices -- as part of the callback -- that the table's partition info is stale. Having a different thread refresh the partition version before the main thread checks if the table version is stale, is likely necessary to trigger the stack trace seen below. e.g: ``` #0

Summary: It is possible for tablet peer's `tablet_` to be null when a rocksdb flush finishes. We call `tablet_->MaxPersistentOpId()` after flush to clean up recently applied transaction state, and this causes a SIGSEGV: ``` * thread #1, name = 'yb-tserver', stop reason = signal SIGSEGV * frame
