Hello,
Quite recently, an interesting bt has been published by "bfoman" about this
bug (see https://bugs.freedesktop.org/attachment.cgi?id=62055) , here are
the top lines :
sal3!rtl_uString_newFromAscii+0x15
wininetbe1_uno!rtl::OUString::createFromAscii+0x40
wininetbe1_uno!WinInetBackend::WinInetBackend+0x1a0
Searching about "createFromAscii" in "wininetbackend" files, I found them in
"wininetbackend.cxx"
The only lines containing "createFromAscii" are :
157 rtl::OUString aProxyList =
rtl::OUString::createFromAscii( lpi->lpszProxy );
158 rtl::OUString aProxyBypassList =
rtl::OUString::createFromAscii( lpi->lpszProxyBypass );
Then I wonder what was "lpi" type and just read some lines above :
126 LPINTERNET_PROXY_INFO lpi = NULL;
Then searching about LPINTERNET_PROXY_INFO gave this url :
http://msdn.microsoft.com/en-us/library/windows/desktop/aa385148%28v=vs.85%29.aspx
"
typedef struct {
DWORD dwAccessType;
LPCTSTR lpszProxy;
LPCTSTR lpszProxyBypass;
} INTERNET_PROXY_INFO, * LPINTERNET_PROXY_INFO;
"
So kept on with attributes "lpszProxy" and "lpszProxyBypass" and its type
LPCTSTR, it gave this link :
http://msdn.microsoft.com/en-us/library/aa383751%28v=vs.85%29.aspx
"
This type is declared in WinNT.h as follows:
#ifdef UNICODE
typedef LPCWSTR LPCTSTR;
#else
typedef LPCSTR LPCTSTR;
#endif
"
On the same page, we can read :
for LPCSTR :
"
A pointer to a constant null-terminated string of 8-bit Windows (ANSI)
characters. For more information, see Character Sets Used By Fonts.
This type is declared in WinNT.h as follows:
typedef __nullterminated CONST CHAR *LPCSTR;
"
and for LPCWSTR :
"
A pointer to a constant null-terminated string of 16-bit Unicode characters.
For more information, see Character Sets Used By Fonts.
This type is declared in WinNT.h as follows:
typedef CONST WCHAR *LPCWSTR;
"
Then going back to createFromAscii to see if it could match with all this :
sal/inc/rtl/ustring.hxx : static OUString createFromAscii( const
sal_Char * value ) SAL_THROW(())
+
sal/inc/sal/types.h : typedef char sal_Char;
Now I wonder if it's ok to use createFromAscii to manage the attributes
"lpszProxy" and "lpszProxyBypass" ? (no ironical question here, just a
beginner question only :-))
Julien.
