Third updated patch - this version also includes copyright notice in added Perl script.
This patch implements a check for such modules at runtime. If modules are not found or unable to load, the test is skipped with
the following message:
[ skipped ] Test needs Perl modules DBI and DBD::mysql
Checks are done via a helper Perl script which looks for the module in a runtime environment that is as similar to that of the
mysqlhotcopy script as possible (thus not intended for Windows environments at this time).
The helper script tells mysql-test about the result by writing information to a temporary file that is later read by mysql-test.
See comments in added files (have_dbi_dbd-mysql.inc and checkDBI_DBD-mysql.pl) for details.
The patch also removes the mysqlhotcopy tests from the list of disabled tests.

|
# Checks for the existence of Perl modules DBI and DBD::mysql as seen from the
|
|
# perl installation used by "external" executable perl scripts, i.e. scripts
|
|
# that are executed as standalone scripts interpreted by the perl installation
|
|
# specified by the "shebang" line in the top of these scripts.
|
|
#
|
|
# If either module is not found, the test will be skipped.
|
|
#
|
|
# For use in tests that call perl scripts that require these modules.
|
|
#
|
|
# This file is intended to work on Unix. Windows may need different treatment.
|
|
# Reasoning:
|
|
# - "shebangs" are not relevant on Windows, but need to be handled here.
|
|
# - Perl scripts cannot be made executable on Windows, interpreter must be
|
|
# specified.
|
|
#
|
|
# Note that if there are multiple perl installations and not all have the
|
|
# required modules, this check may fail even if the perl in path does have
|
|
# the modules available. This may happen if the perl specified by the script's
|
|
# shebang (e.g. #!/usr/bin/perl) does not have these modules, and script is
|
|
# called without specifying the perl interpreter. However, this will be
|
|
# a correct result in cases where a test calls a script with a similar shebang.

# We jump through some hoops since there is no direct way to check if an
|
|
# external command went OK or not from a mysql-test file:
|
|
#
|
|
# - In theory, we could do as simple as "exec perl -MDBI -MDBD::mysql -e 1",
|
|
# however we cannot check the result (exit code) from within a test script.
|
|
# Also, this may not yield the same result as other uses of perl due to the
|
|
# shebang issue mentioned above.
|
|
# - Instead we use a separate helper perl script that checks for the modules.
|
|
# - If the modules are found, the perl script leaves a file which sets a
|
|
# variable that can be read by this file.
|
|
# If the modules are not found, the perl script does not set this variable,
|
|
# but leaves an empty file instead.
|
|
#
|
|
# This is done because there is apparently no direct way to transfer
|
|
# information from perl to the test script itself.
