Bug 95741 – patch to add: emerge info <package(s)>

• Product: Portage Development
• Status: RESOLVED FIXED

[Description Nathaniel McCallum (RETIRED) 2005-06-10 21:45:41 UTC]

The following patch adds an optional package argument(s) to emerge info.  emerge will then search for the specified packages.  If they are installed and any of the settings for these packages are different than what the current system has, those differences are displayed.

For instance, if you have package 'foo' that was installed.  After you installed foo, you changed your CFLAGS.  When you do 'emerge info', all you get is what the current settings are (not what you emerged foo as).  Thus 'emerge info foo' provides both current system settings and the old CFLAGS for foo.

You should use portage.db[portage.root]["vartree"].dbapi.aux_get(pkg, 
mydesiredvars) instead of reading the files directly. Other than that, it 
looks fine.

I ended up making a few small changes. In particular, I got rid of the 
mysettings temporary and compared directly to portage.settings. There were 
also two small bugs: 
 
1) diff_found was in the wrong place which would cause the per-package header 
to be printed for all packages after the first differing package. 
2) Using None when a variable is not set globally would cause that variable to 
always be printed for every package. ("" != None)

Fixed on or before 2.0.51.22-r1

Looking through the batch of bugs, I'm not sure that some of these are 
actually fixed in stable. Others, the requirements have possibly changed after 
the initial fix was committed. 
 
If you think this bug has been closed incorrectly, please reopen or ask that 
it be reopened.

Doesn't look like it to me.

This feature would be really useful.  It shouldn't be much work to sync it up with trunk, so I'll go ahead and do that...

An updated version of this patch is in svn r3834.
