#!/usr/bin/perl
# -*- cperl -*-

# This is a transformation of the "mysql-test-run" Bourne shell script
# to Perl. This is just an intermediate step, the goal is to rewrite
# the Perl script to C. The complexity of the mysql-test-run script
# makes it a bit hard to write and debug it as a C program directly,
# so this is considered a prototype.
#
# Because of this the Perl coding style may in some cases look a bit
# funny. The rules used are
#
#   - The coding style is as close as possible to the C/C++ MySQL
#     coding standard.
#
#   - Where NULL is to be returned, the undefined value is used.
#
#   - Regexp comparisons are simple and can be translated to strcmp
#     and other string functions. To ease this transformation matching
#     is done in the lib "lib/mtr_match.pl", i.e. regular expressions
#     should be avoided in the main program.
#
#   - The "unless" construct is not to be used. It is the same as "if !".
#
#   - opendir/readdir/closedir is used instead of glob()/<*>.
#
#   - All lists of arguments to send to commands are Perl lists/arrays,
#     not strings we append args to. Within reason, most string
#     concatenation for arguments should be avoided.
#
#   - sprintf() is to be used, within reason, for all string creation.
#     This mtr_add_arg() function is also based on sprintf(), i.e. you
#     use a format string and put the variable argument in the argument
#     list.
#
#   - Functions defined in the main program are not to be prefixed,
#     functions in "library files" are to be prefixed with "mtr_" (for
#     Mysql-Test-Run). There are some exceptions, code that fits best in
#     the main program, but are put into separate files to avoid
#     clutter, may be without prefix.
#
#   - All stat/opendir/-f/ is to be kept in collect_test_cases(). It
#     will create a struct that the rest of the program can use to get
#     the information. This separates the "find information" from the
#     "do the work" and makes the program more easy to maintain.
#
#   - At the moment, there are tons of "global" variables that control
#     this script, even accessed from the files in "lib/*.pl". This
#     will change over time, for now global variables are used instead
#     of using %opt, %path and %exe hashes, because I want more
#     compile time checking, that hashes would not give me. Once this
#     script is debugged, hashes will be used and passed as parameters
#     to functions, to more closely mimic how it would be coded in C
#     using structs.
#
#   - The rule when it comes to the logic of this program is
#
#       command_line_setup() - is to handle the logic between flags
#       collect_test_cases() - is to do its best to select what tests
#                              to run, dig out options, if needs restart etc.
#       run_testcase()       - is to run a single testcase, and follow the
#                              logic set in both above. No, or rare file
#                              system operations. If a test seems complex,
#                              it should probably not be here.
#
# A nice way to trace the execution of this script while debugging
# is to use the Devel::Trace package found at
# "http://www.plover.com/~mjd/perl/Trace/" and run this script like
# "perl -d:Trace mysql-test-run.pl"
