A segmemnt written with Lucene70Codec failes if it ties to update
a DV field that didn't exist in the index before it was upgraded to
Lucene80Codec. We bake the DV format into the FieldInfo when it's used
the first time and therefor never go to the codec if we need to update.
yet on a field that didn't exist before and was added during an indexing
operation we have to consult the coded and get an exception.
This change fixes this issue and adds the relevant bwc tests.
The case when all values are the the same on a numeric field update
is common for soft_deletes. With the new infrastucture for buffering
DV updates we can gain an easy win by specializing the applied updates
if all values are the same.
Today we are using a LinkedHashMap to buffer doc-values updates in
BufferedUpdates. This on the one hand uses an Object based datastructure
and on the other requires re-encoding the data into a more compact representation
once the BufferedUpdates are frozen. This change uses a more compact represenation
for the updates already in the BufferedUpdates in a parallel-array like datastructure
that can be reused in FrozenBufferedDeletes. It also adds an much simpler to use
API to consume the updates and allows for internal memory optimization for common
case updates.
Prior to this commit, ReplicationHandler had a few inconsistencies
in how it reported errors:
- Sometimes the 'status' field was used as an enum (e.g. 'success'
v. 'failure'. Elsewhere it is used to hold error messages.
- Sometimes an explicit 'message' field was used, but often not.
- Sometimes a stack trace was provided in place of an error message.
This commit tweaks the various error cases in ReplicationHandler to
report errors consistently. 'status' is always an enum-type value. A
'message' field is provided for all errors, with an optional 'exception'
field.
This commit replaces the `try { doX(); fail(); }` pattern with the
`expectThrows` test helper, which was created for this purpose.
