Use die_errno() instead of die() when checking syscalls
Lots of die() calls did not actually report the kind of error, which can leave the user confused as to the real problem. Use die_errno() where we check a system/library call that sets errno on failure, or one of the following that wrap such calls: Function Passes on error from -------- -------------------- odb_pack_keep open read_ancestry fopen read_in_full xread strbuf_read xread strbuf_read_file open or strbuf_read_file strbuf_readlink readlink write_in_full xwrite Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>
