From 5ff247ac0cc9b2d09c8c24bd0c8df12eed94aebc Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Sat, 19 Aug 2017 07:32:37 +0200 Subject: [PATCH] archive: don't queue excluded directories Reject directories with the attribute export-ignore already while queuing them. This prevents read_tree_recursive() from descending into them and this avoids write_archive_entry() rejecting them later on, which queue_or_write_archive_entry() is not prepared for. Borrow the existing strbuf to build the full path to avoid string copies and extra allocations; just make sure we restore the original value before moving on. Keep checking any other attributes in write_archive_entry() as before, but avoid checking them twice.
