Bug 125674 – perl-cleaner efficiency and speed

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Wade Fitzpatrick 2006-03-10 00:44:44 UTC]

app-admin/perl-cleaner-1.01 is horrendously slow due to massive use of grep instead of fgrep. Also should make use of esearch cache if available.

Stand by for patch...

Patch to replace grep with fgrep where appropriate

Also fixes some formatting and adds a vim modeline

Patch to add esearch speed improvements

Includes fgrep fixes and adds support of esearch cache so we don't have to keep calling emerge all the time.

Without this patch:
real    42m31.915s
user    36m9.454s
sys     0m23.254s

With this patch:
real    0m3.895s
user    0m2.311s
sys     0m0.405s

Both returned exactly the same list of packages to emerge (103 packages)

I'll admit I haven't had a chance to look over the patches yet - but where were you when we put this together? :) Thanks, will take a peak soon,

applied for the most part. ran into a little problem with some overzealous fgrep replacements, but all in all this is in the 1.04 series
