Several pieces of documentation state that USE-flags may be manipulated by setting the USE environment variable. This does not work as documented. The USE environment variable works as documented to *add* USE-flags, but it does not work consistently to *remove* USE-flags. To reproduce: - Go to any gentoo 1.4 system with a generic configuration. - Run "emerge info" and note that kde is included in the USE set printed. - Now run this command: USE='-kde' emerge info - Note that kde is *still* included in the output list, although it was explicitly removed using the highest-priority mechanism. Reproducible: Always Steps to Reproduce: 1. Go to any gentoo 1.4 system with a generic configuration. 2. Run "emerge info" and note that kde is included in the USE set printed. 3. Now run this command: USE='-kde' emerge info Actual Results: 'kde' is included in the output list from both commands Expected Results: The 'kde' USE-flag should not be included in the output from step 3. % USE='-kde' emerge info <------ Note USE='-kde' setting!

Created attachment 26255 [details, diff] Temporary Fix This is more of a hack than a fix. The problem is that regenerate() is called four times during initialisation. One of those times, configdict["env"]["USE"] is replaced with the processed USE flags. Thus by the last time round, any -flag set is not honored. This hack gets around this by copying configdict["backupenv"]["USE"] to configdict["env"]["USE"] if it exists at the start of each regenerate().
*** Bug 42737 has been marked as a duplicate of this bug. ***
I think this is all we should fix. portage.py Line 6270 in cvs. -settings.regenerate() # XXX: Regenerate use after we get a vartree -- GLOBAL +settings.reset() # XXX: Regenerate use after we get a vartree -- GLOBAL maybe, we shouldn't call regenerate() function from out of config class..
Fixed in CVS
Closing it out, can't duplicate it w/ .50-r9 or .51_pre17.
