From e3d42c4773bccebb50f01b108d20b06c6a11e615 Mon Sep 17 00:00:00 2001 From: Jens Lehmann Date: Mon, 18 Jan 2010 21:26:18 +0100 Subject: Performance optimization for detection of modified submodules In the worst case is_submodule_modified() got called three times for each submodule. The information we got from scanning the whole submodule tree the first time can be reused instead. New parameters have been added to diff_change() and diff_addremove(), the information is stored in a new member of struct diff_filespec. Its value is then reused instead of calling is_submodule_modified() again. When no explicit "-dirty" is needed in the output the call to is_submodule_modified() is not necessary when the submodules HEAD already disagrees with the ref of the superproject, as this alone marks it as modified. To achieve that, get_stat_data() got an extra argument.
