Compacting sorted srch files can take multiple transactions because they can be very large. Each transaction resumes at a byte offset in a block where the previous transaction stopped. The resuming code tests that the byte offsets are sane but had a mistake in testing the offset to skip to. It returned an error if the compaction resumed from the last possible safe offset for decoding entries. If a system is unlucky enough to have a compaction transaction stop at just this offset then compaction stops making forward progress as each attempt to resume returns an error. The fix allows continuation from this last safe offset while returning errors for attempts to continue *past* that offset. This matches all the encoding code which allows encoding the last entry in the block at this offset. Signed-off-by: Zach Brown <zab@versity.com>
