[Aptitude-devel] Bug#812829: -o no longer works

[積丹尼 Dan Jacobson]

Package: aptitude
Version: 0.7.5-3

file:///usr/share/doc/aptitude/html/en/ch02s05s05.html says

aptitude's configuration is read from the following sources, in order:

 1. Configuration file options specified on the command-line.

 2. The user's configuration file, ~/.aptitude/config. This file is overwritten when the user modifies settings in the Options menu.

 3. The system configuration file, /etc/apt/apt.conf.

 4. The system configuration fragment files, /etc/apt/apt.conf.d/*.

 5. The file specified by the APT_CONFIG environment variable (if any).

 6. Default values stored in /usr/share/aptitude/aptitude-defaults.

 7. Default values built into aptitude.

but neglects to mention at what level -o on the command line overrides
any of these. (DOCUMENTATION) BUG1. In fact it doesn't even politely
mention -o one little bit.

In fact it doesn't anymore.

The man page says

       -o <key>=<value>
           Set a configuration file option directly; for instance, use -o
           Aptitude::Log=/tmp/my-log to log aptitude's actions to /tmp/my-log.
           For more information on configuration file options, see the section
           "Configuration file reference" in the aptitude reference manual.

       -v, --verbose
           Causes some commands (for instance, show) to display extra
           information. This may be supplied multiple times to get more and
           more information.

           This corresponds to the configuration option
           Aptitude::CmdLine::Verbose.

So
# aptitude why python-requests
i   python-pip Depends python-requests
# aptitude -v why python-requests|wc
  56676  285614 3690866
# aptitude -o Aptitude::CmdLine::Verbose=1 why python-requests|wc
      1       4      39
BUG2.

Likewise, if one has
Aptitude::CmdLine::Verbose 1;
in their configuration file,
-o Aptitude::CmdLine::Verbose=0
will no longer turn it off.

Here we see that it must be an aptitude problem, not an apt problem:

# apt-config -o Aptitude::CmdLine::VerboseX=0 dump|grep -i verb
Aptitude::CmdLine::Verbose "1";
Aptitude::CmdLine::VerboseX "0";
CommandLine::AsString "apt-config -o Aptitude::CmdLine::VerboseX=0 dump";
# apt-config -o Aptitude::CmdLine::Verbose=0 dump|grep -i verb
Aptitude::CmdLine::Verbose "0";
CommandLine::AsString "apt-config -o Aptitude::CmdLine::Verbose=0 dump";
