Worst AutoIt Bug Award

[Jon]

Is this one of the worst bugs ever or what? #1844

It took me a while to see what the bug was saying...eeeeek.

Edit: IIRC SplashTextOn was one of the very early pieces of code. But still....

If the variant class still has the operators overloaded, I can see why someone could make an easy mistake like that.

[Jon]

I've not looked at the code yet but it's almost certainly someone casting away a string's const-ness. I'm pretty sure it wasn't me as well so I get to be preachy about it too

[Valik]

If it's casting away const it's doing so using the C cast method:

Find all "const_cast", Subfolders, Find Results 1, "Entire Solution"
  C:\Data\My Programs\C++\Autoit\autoit\src\script_inet.cpp(336):       // const_cast is used here because the function expects LPVOID.  The casts are safe, though.
  C:\Data\My Programs\C++\Autoit\autoit\src\script_inet.cpp(337):       InternetSetOption(hInet, INTERNET_OPTION_PROXY_USERNAME, const_cast<LPTSTR>(sProxyUser.c_str()), static_cast<DWORD>(sProxyUser.length() + 1) );
  C:\Data\My Programs\C++\Autoit\autoit\src\script_inet.cpp(338):       InternetSetOption(hInet, INTERNET_OPTION_PROXY_PASSWORD, const_cast<LPTSTR>(sProxyPass.c_str()), static_cast<DWORD>(sProxyPass.length() + 1));
  C:\Data\My Programs\C++\Autoit\autoit\src\CreateProcessSimple.cpp(206):   ProfileInfo.lpUserName = const_cast<LPWSTR>(lpUsername);
  C:\Data\My Programs\C++\Autoit\autoit\src\script_inet.cpp(336):       // const_cast is used here because the function expects LPVOID.  The casts are safe, though.
  C:\Data\My Programs\C++\Autoit\autoit\src\script_inet.cpp(337):       InternetSetOption(hInet, INTERNET_OPTION_PROXY_USERNAME, const_cast<LPTSTR>(sProxyUser.c_str()), static_cast<DWORD>(sProxyUser.length() + 1) );
  C:\Data\My Programs\C++\Autoit\autoit\src\script_inet.cpp(338):       InternetSetOption(hInet, INTERNET_OPTION_PROXY_PASSWORD, const_cast<LPTSTR>(sProxyPass.c_str()), static_cast<DWORD>(sProxyPass.length() + 1));
  C:\Data\My Programs\C++\Autoit\autoit\src\CreateProcessSimple.cpp(206):   ProfileInfo.lpUserName = const_cast<LPWSTR>(lpUsername);
  Matching lines: 8 Matching files: 4   Total files searched: 294

I wrote all those const_cast and all of them are correct. My code is const-correct, the C API we are using is not, thus I must cast away const.

Is that worst as in the bug report being difficult or worst as in "why is the splash modifying the variable"?

[Jon]

The modifying bit.

[Jon]

LPCTSTR szTemp = _tcstok((LPTSTR)szText, _T("\r\n") );

[Valik]

Ugh. _tcstok() modifies the string, that's why it doesn't take a fucking constant. Sigh. Wonder how many more stupid lines like that are in the code?

[jvanegmond]

$input = "Line one" & @CRLF & "Line two"

$result = StringGetFirstLine($input)

MsgBox(0, "", $result)

Func StringGetFirstLine($str)
    SplashTextOn("", $str, -1, -1, -1, -1, 32 + 1)
    SplashOff()
    Return $str
EndFunc

Funny function Mandar!

Func StringGetFirstLine($str)
    SplashTextOn("", $str, -10, -10, 0, 0, 32 + 1)
    SplashOff()
    Return $str
EndFunc

Now it is perfect!
