From c83931cbb3516563949d283fe46453a35cd35977 Mon Sep 17 00:00:00 2001 From: Andrew Thompson Date: Wed, 19 Sep 2012 16:54:01 -0400 Subject: Fix printing the empty binary at depth 1 with ~W A case clause ordering problem is causing the empty binary to be printed as <<...>> rather than the correct <<>> when using ~W with a depth of 1. Add new tests to verify correct behaviour. --- lib/stdlib/test/io_SUITE.erl | 17 +++++++++++++++-- 1 file changed, 15 insertions(+), 2 deletions(-) (limited to 'lib/stdlib/test/io_SUITE.erl') diff --git a/lib/stdlib/test/io_SUITE.erl b/lib/stdlib/test/io_SUITE.erl index bb02a879c2..74fcdcc7d2 100644 --- a/lib/stdlib/test/io_SUITE.erl +++ b/lib/stdlib/test/io_SUITE.erl @@ -27,7 +27,8 @@ otp_6282/1, otp_6354/1, otp_6495/1, otp_6517/1, otp_6502/1, manpage/1, otp_6708/1, otp_7084/1, otp_7421/1, io_lib_collect_line_3_wb/1, cr_whitespace_in_string/1, - io_fread_newlines/1, otp_8989/1, io_lib_fread_literal/1]). + io_fread_newlines/1, otp_8989/1, io_lib_fread_literal/1, + io_lib_print_binary_depth_one/1]). %-define(debug, true). @@ -62,7 +63,8 @@ all() -> otp_6282, otp_6354, otp_6495, otp_6517, otp_6502, manpage, otp_6708, otp_7084, otp_7421, io_lib_collect_line_3_wb, cr_whitespace_in_string, - io_fread_newlines, otp_8989, io_lib_fread_literal]. + io_fread_newlines, otp_8989, io_lib_fread_literal, + io_lib_print_binary_depth_one]. groups() -> []. @@ -2021,3 +2023,14 @@ io_lib_fread_literal(Suite) when is_list(Suite) -> ?line {done,{error,{fread,input}},_} = io_lib:fread(C2, eof, " d"), ?line {done,{ok,[]},[]} = io_lib:fread(C2, "d\n", " d"), ok. + +io_lib_print_binary_depth_one(doc) -> + "Test binaries printed with a depth of one behave correctly"; +io_lib_print_binary_depth_one(Suite) when is_list(Suite) -> + ?line "<<>>" = fmt("~W", [<<>>, 1]), + ?line "<<>>" = fmt("~P", [<<>>, 1]), + ?line "<<...>>" = fmt("~W", [<<1>>, 1]), + ?line "<<...>>" = fmt("~P", [<<1>>, 1]), + ?line "<<...>>" = fmt("~W", [<<1:7>>, 1]), + ?line "<<...>>" = fmt("~P", [<<1:7>>, 1]), + ok. -- cgit v1.2.3
