This is hard to explain. I run this on a Windows XP machine:
{{{
C:\project>manage.py dbshell
C:\project>Welcome to the MySQL monitor. Commands end with ; or \
g.
Your MySQL connection id is 6902
Server version: 5.0.51a-community-nt-log MySQL Community Edition (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql>
}}}
Basically what happens is that every other command goes to either the
mysql.exe client or the original command line shell (cmd.exe) in
alternating order. So if you keep pressing enter/return, you get this:
{{{
mysql>
C:\project>
mysql>
C:\project>
}}}
And if you do type in "show tables;" three times, you get this:
{{{
mysql> show tables;
'show' is not recognized as an internal or external command,
operable program or batch file.
C:\project>show tables;
(shows tables here)
26 rows in set (0.00 sec)
mysql> show tables;
'show' is not recognized as an internal or external command,
operable program or batch file.
}}}
The first response (show is not recognized) is from cmd.exe. The second
result is from mysql.exe. The third result is again from cmd.exe.
I think that manage.py is executing the mysql.exe process concurrently
with the opening command line, and the STDIN and STDOUT are being merged
together. Since they both block for input, when you enter a command in
one and press enter, the "focus" switches to the other process.
All of this works on unix, so it seems to be a Windows-only problem. Can
anyone else confirm?

Django... production server is running 1.0, so I can't upgrade my dev
machine at the moment).
