86a6d358f7
Numerous changes were made to git functions to use an object_id structure rather than sending sha1 hashes as raw unsigned character arrays. The functions that affect cgit are: parse_object, lookup_commit_reference, lookup_tag, lookup_tree, parse_tree_indirect, diff_root_tree_sha1, diff_tree_sha1, and format_display_notes. Commit b2141fc (config: don't include config.h by default) made it necessary to that config.h be explicitly included when needed. Commit 07a3d41 (grep: remove regflags from the public grep_opt API) removed one way of specifying the ignore-case grep option. Signed-off-by: Jeff Smith <whydoubt@gmail.com>
