From 96beef8c2efaab06f703991ed7802b8cef4c00e3 Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Sat, 4 Apr 2009 22:59:26 +0200 Subject: sha1-lookup: add new "sha1_pos" function to efficiently lookup sha1 This function has been copied from the "patch_pos" function in "patch-ids.c" but an additional parameter has been added. The new parameter is a function pointer, that is used to access the sha1 of an element in the table.
