The test case rpl_binlog_corruption fails on windows because when
adding a line to the binary log index file it gets terminated
with a CR+LF (which btw, is the normal case in windows, but not on
Unixes - LF). This causes mismatch between the relay log names,
causing mysqld to report that it cannot find the log file.
We fix this by creating the instrumented index file through
mysql, ie, using SELECT ... INTO DUMPFILE ..., as opposed on
relying on ultimatly OS commands like: -- echo "..." >
index. These changes go into the file and make the procedure
platform independent:
include/setup_fake_relay_log.inc
Side note: when using SELECT ... INTO DUMPFILE ..., one needs to
check if mysqld is running with secure_file_priv. If it is, we do
it in two steps: 1. create the file on the allowed location;
2. move it to the datadir. If it is not, then we just create the
file directly on the datadir (so previous step 2. is not needed).
Path composition for the relay log file that is stored into the relay index
file was not correct for windows.
mysql-test language does not provide primitives for portable path composition.
Fixed with storing only the basename part of the external "fake" relay log into
the relay index file.
Safety of removal of the dirname part of the relaylog is provided by logics of
`setup_fake_relay_log' that places the fake file into @@datadir directory.
Fixing pb failures caused by mtr invokes the test with --tmpdir to which
there are sensitive operations in the test
and setup_fake_relay_log.inc also needed --secure-file-priv for its own separate
directory.
Fixed with removing SELECT INTO OUTFILE and deploying --exec echo instead in the marco.
The test's opt file should contain --secure-file-priv=$MYSQL_TEST_DIR as the test
operations deal with files located in $MYSQL_TEST_DIR.
Problem: When an Incident_log_event contains a bad incident number on disk,
the server crashes with an assertion.
Fix: Don't validate input with assertions. Use errors.
