Bugzilla Bug 92479

if you're emerging a specific version of a package (=pkgname-1.0.0), and you
attempt to tab-complete when the version number entered so far is illegitimate,
instead of not completing, you'll get "\* " appended to the command line.



Reproducible: Always
Steps to Reproduce:
1. emerge -aDtv =gentoo-bashcomp-1<tab>

Actual Results:  
root ~ # emerge -aDtv =gentoo-bashcomp-1\* 

Expected Results:  
since there is no version of gentoo-bashcomp starting with 1...

<beep>
root ~ # emerge -aDtv =gentoo-bashcomp-1

this occurs with any non-existant package version, subversion, beta date,
r-bump, etc.

my installed version is gentoo-bashcomp-20050506.

doesnt seem to just happen with versions either

emerge =non-existent<TAB> does the same thing.

do shopt -qs nullglob in subshell

The completion uses the cache in PORTDIR/metadata/cache to complete versions of
packages. There is a for-loop that removes the 'category/' prefix for every
expansion of *-*/COMPLETEME*.
Thus, if *-*/COMPLETEME* expands to nothing, '*-*/' is removed and
'COMPLETEME<tab>' becomes 'COMPLETEME*'.

There are two fixes I can think of (The patch uses the first one):
1) shopt -qs nullglob in the subshell ("If the nullglob option is set, and no
matches are found, the word is removed") or
2) [[ -f $i ]] && echo ${i##*/}

heh victim of my own advice.  I was just telling slarti the other day how you
should always check for existence when using glob loops :)

Anyways, it's fixed upstream.  Will be fixed next release.

20050516 released.
