From 8f420b9272e526097a73ad10ce74ce3edbb67b9e Mon Sep 17 00:00:00 2001 From: Kurtis Rader Date: Sun, 22 May 2016 19:00:13 -0700 Subject: Fix wide char related tests on Cygwin This makes the wide char tests run by `./fish_tests` pass on systems where sizeof wchar_t is two (e.g., Cygwin). In doing so it corrects several problems with the underlying code in module *utf8.cpp* such as allowing five and six byte UTF-8 sequences. They were allowed by the original Unicode proposal but are not allowed by the adopted standard. --- src/common.cpp | 31 ++++++--- src/fish_tests.cpp | 188 ++++++++++++++++++++++------------------------------- src/utf8.cpp | 45 ++++--------- src/utf8.h | 2 - 4 files changed, 112 insertions(+), 154 deletions(-) diff --git a/src/common.cpp b/src/common.cpp index 91b08824..1ad51482 100644 --- a/src/common.cpp +++ b/src/common.cpp @@ -106,8 +106,8 @@ demangled_backtrace(int max_frames, int skip_levels) { return backtrace_text; } -void __attribute__((noinline)) show_stackframe(const wchar_t msg_level, int frame_count, - int skip_levels) { +void __attribute__((noinline)) +show_stackframe(const wchar_t msg_level, int frame_count, int skip_levels) { ASSERT_IS_NOT_FORKED_CHILD(); // TODO: Decide if this is still needed.
