MDEV-32555 wrong result with an index and a partially null-rejecting condition
ref->null_rejecting is a key_part_map. we need to check
the bit corresponding to the particular store_key.
Note that there are no store_key objects for const ref parts.
MDEV-32507 Spider: Use $MTR_SUITE_DIR for init-file files
This should fix certain CI builds where the spider suite test files
and the main suite test files do not follow the same relative paths
relations as the mariadb source.
MDEV-32552 Write-ahead logging is broken for freed pages
buf_page_free(): Flag the freed page as modified if it is found in
the buffer pool.
buf_flush_page(): If the page has been freed, ensure that the log
for it has been durably written, before removing the page
from buf_pool.flush_list.
FindBlockX: Find also MTR_MEMO_PAGE_X_MODIFY in order to avoid an
occasional failure of innodb.innodb_defrag_concurrent, which involves
freeing and reallocating pages in the same mini-transaction.
This fixes a regression that was introduced in
commit a35b4ae89871d8184f04abb112c385481d557dbb (MDEV-15528).
This logic was tested by commenting out the $shutdown_timeout line
from a test and running the following:
A breakpoint in the modified buf_flush_page() was hit, and the
FIL_PAGE_LSN of that page had been last modified during the
mtr_t::commit() of a mini-transaction where buf_page_free()
had been executed on that page.
