From f4f19fb63449e1beee02b0ec845319f7115fa9d0 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Mon, 16 Nov 2009 10:56:25 -0500 Subject: [PATCH] diffcore-break: free filespec data as we go As we look at each changed file and consider breaking it, we load the blob data and make a decision about whether to break, which is independent of any other blobs that might have changed. However, we keep the data in memory while we consider breaking all of the other files. Which means that both versions of every file you are diffing are in memory at the same time. This patch instead frees the blob data as we finish with each file pair, leading to much lower memory usage.
