            To track the Fault 2 mentioned above, I filed the following issue:
            MDEV-14049 InnoDB fails to refuse startup when a file is not found in crash recovery

            One last dump before I abandon the dataset. Here are the page headers for all doublewrite buffer entries that are not referring to the system tablespace (I separately verified that the maximum space ID was less than 0xff):

            There are some entries referring to tablespace 0xb2 (t2.ibd) and many to some earlier tablespaces (such as 0x9e, 0xa2, 0xb0) which were probably created and dropped by earlier tests.
            This leads me to believe that in the unexpectedly-not-refused startup attempt "Fault 2", the doublewrite buffer was not emptied, and we indeed did not have doublewrite entries for t3.ibd before the kill. So, the doublewrite buffer bug should affect MariaDB 10.2 as well.

            marko Marko Mäkelä added a comment - To track the Fault 2 mentioned above, I filed the following issue: MDEV-14049 InnoDB fails to refuse startup when a file is not found in crash recovery One last dump before I abandon the dataset. Here are the page headers for all doublewrite buffer entries that are not referring to the system tablespace (I separately verified that the maximum space ID was less than 0xff): od -t x1 -Ax -N

dropped by earlier tests. This leads me to believe that in the unexpectedly-not-refused startup attempt "Fault 2", the doublewrite buffer was not emptied, and we indeed did not have doublewrite entries for t3.ibd before the kill. So, the doublewrite buffer bug should affect MariaDB 10.2 as well.

            Test report from 10.1 and Windows 32-bit: The difference between successful test run and failed one is that in innodb_plugin when page 1 from tablespace 0 is dirtied it uses buffered doublewrite write for that dirtied page. When test fails that buffered write does not happen i.e. server is killed before the buffered doublewrite page is written.

            MDEV-15325 shows how to repeat this deterministically on GNU/Linux.

            I wonder if we still encounter this. With an rr replay trace of the killed server and the failed recovery this should be trivial to analyze.

            Starting with 10.5 the code is very different, mostly due to MDEV-23855, which streamlined the page flushing and made the doublewrite buffer use asynchronous writes.

            In 10.1 (which finally reached its end of life in 2020), the test innodb.doublewrite would also fail due to other reasons (memory corruption after InnoDB failed to start up). The memory leaks and corruption on failed InnoDB startup were only fixed in the 10.2 series.

            The last occurrences of innodb.doublewrite test failures that I observed for other than 10.1 branches were:

            branch revision platform timestamp
            10.2 aed2050e40cb332d54e8d40eb7242309 win32-debug 2018-01-01 15:27:00

            All 10.4 failures (there were very few of them in total) that I checked were actually due to MDEV-20159. Also the most recent failures for 10.2 and 10.3 appear to be for something else.

            It seems that MDEV-15325 must have fixed this in March 2018. Also MDEV-12699 and related improvements reduced the need for the doublewrite buffer, but that was fixed in April 2019, much later.
