Fixed bug #31036: Using order by with archive table crashes server.
1. Memory overrun have been fixed.
2. Server failure on assertion has been fixed.
storage/archive/azio.c:
Fixed bug #31036.
The ha_archive::rnd_pos function has been modified to take
into account the result of the azseek function and
to return HA_ERR_CRASHED_ON_USAGE in case of seek error.
storage/archive/ha_archive.cc:
Fixed bug #31036.
1. Memory overrun has been fixed: maximal sizes of azio_stream::inbuf
and azio_stream::outbuf was mixed.
2. Zero value of the output parameter of the azread function was
incorrectly interpreted by the azseek function: after the first
successful read attempt the execution of the azseek loop was
interrupted and negative value was returned.
(See ha_archive::rnd_pos: that negative value was silently ignored,
and an incomplete data was used, for example, as a size of a packed
record, and server failed with the assertion:
"row_len <= record_buffer->length".)
mysql-test/t/archive.test:
Added test case for bug #31036.
mysql-test/r/archive.result:
Added test case for bug #31036.
