Hi Henrik,
Thanks again for the help. I think I have fixed it. Let me try to elaborate
my fix:
I put the following logging in drizzled.cc and recompiled drizzle:
if (vm.count("no-defaults")) {
cout << "Do not pick default conf: "
<< vm["no-defaults"].as<bool>() << ".\n";
} else {
cout << "pick default conf .\n";
}
Then I restarted drizzle server and drizzle client. Irrespective of the
'no-defaults' option, the code always go inside the if block rather than
the else block. But the value of vm["no-defaults"].as<bool>() is 'false'
if I don't provide "--no-defaults" in the command line. If I provide
"--no-defaults" in the command line then vm["no-defaults"].as<bool>() is
true:
./drizzled/drizzled ==> vm["no-defaults"].as<bool>() ==> false
./drizzled/drizzled ==> vm["no-defaults"].as<bool>() ==> true
So then I went to read Boost documentation from
http://www.boost.org/doc/libs/1_49_0/doc/html/program_options/tutorial.htmland
I figured out that the boost program options have not been used in
proper context in that 'if' statement. So I have replaced the code:
Old code: if (vm.count("no-defaults"))
New Code: if (! vm["no-defaults"].as<bool>())
I recompiled drizzle and everything looks good now. Now drizzle ignores
drizzled.cnf if we pass --no-defaults in the command line options.
If you give me green signal then I can go ahead with creating the branch
for this and propose it for merging.
In the mean time I will do further testing.
Thanks for the help.
