From 11192484fa320cd233849441bd00ddf58964de42 Mon Sep 17 00:00:00 2001 From: Eneas U de Queiroz Date: Thu, 20 Feb 2020 18:29:04 -0300 Subject: [PATCH] build: reduce number of files passed to ipk-remove Instead of using xargs to pass a huge number of files to script/ipkg-remove, which will usually pick only one, use a more restrictive wildcard so that, currently, at the most 325 files are examined, instead of up to over 2,300. The 325-file package is python, which is picking up python3* ipks. It is about to be removed. Runner-up is ddns-scripts with 7 files. This makes a second run of make package/luci/compile go from real 16.40s; user 17.42s; sys 2.73s to real 10.71s; user 9.51s; sys 1.27s There is a caveat though: if one were to remove the ABI_VERSION of a package that ends in a digit [0-9], then the old package ipk will not be removed from the bin directory by make package/abc2/clean.
