Subject [jira] Closed: (STDCXX-104) [Mac OS X 10.2.8] Use of wcscoll and wcslen without checking guards
Date Wed, 30 May 2007 16:07:16 GMT

     [ https://issues.apache.org/jira/browse/STDCXX-104?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew Black closed STDCXX-104.
-------------------------------

    Resolution: Fixed

I'm not certain about the chronology, but http://svn.apache.org/viewcvs?view=rev&rev=369552
describes basically the same change as was described in the lose patch.  As such, I'm closing
the incident, though I no longer have the 10.2.8 operating system installed on the box I was
using when this incident was filed, so I'm unable to check how things compile on that operating
system at this time.

> In src/collate.cpp, collate_byname<wchar_t>::do_compare() uses wcscoll without
checking if _RWSTD_NO_WCSCOLL and/or _RWSTD_NO_WCSCOLL_IN_LIBC are undefined (my reading of
the macro names is that a version of wcscoll is availible if either is defined)
> In src/wcodecvt.cpp, __rw_libc_do_out uses wcslen().  As I read things, there should
be a macro pair _RWSTD_NO_WCSLEN and/or _RWSTD_NO_WCSLEN_IN_LIBC, but I don't think either
macro is defined/undefined in the generated config.h (I didn't think to bring it in after
the experiements over the weekend)
