From: Christian Couder Date: Thu, 26 Mar 2009 04:56:02 +0000 (+0100) Subject: bisect: use "bisect--helper" and remove "filter_skipped" function X-Git-Tag: v1.6.3-rc0~7^2~6 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=23b5f18b50c15155f79618522b5721b880eceb65;p=git.git bisect: use "bisect--helper" and remove "filter_skipped" function Use the new "git bisect--helper" builtin. It should be faster and safer instead of the old "filter_skipped" shell function. And it is a first step to move more shell code to C. As the output is a little bit different we have to change the code that interpret the results. But these changes improve code clarity.
