Примеры ошибок, обнаруженных с помощью диагностики V501

V501. Identical sub-expressions to the left and to the right of 'foo' operator.


Audacity

V501 There are identical sub-expressions to the left and to the right of the '-' operator. Audacity voicekey.cpp 304


sampleCount VoiceKey::OnBackward (....) {
  ....
  int atrend = sgn(buffer[samplesleft - 2]-
                   buffer[samplesleft - 1]);
  int ztrend = sgn(buffer[samplesleft - WindowSizeInt-2]-
                   buffer[samplesleft - WindowSizeInt-2]);
  ....
}

A Copy-Paste error. In the last line 1 should be subtracted instead of 2.


Crystal Space 3D SDK

V501 There are identical sub-expressions to the left and to the right of the '&&' operator. plgcsopcode icelss.h 69


inline_ bool Contains(const LSS& lss)
{
  // We check the LSS contains the two spheres
  // at the start and end of the sweep
  return Contains(Sphere(lss.mP0, lss.mRadius)) &&
         Contains(Sphere(lss.mP0, lss.mRadius));
}

A Copy-Paste error. The lss.mP1 variable should have been probably used when calling the Sphere function for the second time.


Shareaza

V501 There are identical sub-expressions to the left and to the right of the '==' operator: nCmd == nCmd Shareaza wndpacket.cpp 477


void CPacketWnd::OnContextMenu(CWnd* /*pWnd*/, CPoint point)
{
  ....

  if ( GetAsyncKeyState( VK_SHIFT ) & 0x8000 )
  {
    m_bTypeED = ( nCmd == nCmd ) ? TRUE : FALSE;
  }
  ....
}

Xpdf

V501 There are identical sub-expressions to the left and to the right of the '||' operator: ( res -> pw == 0 ) || ( res -> pw == 0 ) mupdf pi.c 219


static bool pi_next_rpcl(opj_pi_iterator_t * pi) {
  ....
  if ((res->pw==0)||(res->pw==0)) continue;

  ....
}

Most likely this is what should be written here: (res->pw==0)||(res->ph==0).


XUIFramework

V501 There are identical sub-expressions to the left and to the right of the '||' operator. Borne resizedlg.cpp 157


HDWP CItemCtrl::OnSize(....)
{
  ....
  if (m_styTop == CST_ZOOM ||
      m_styTop == CST_ZOOM ||
      m_styBottom == CST_DELTA_ZOOM ||
      m_styBottom == CST_DELTA_ZOOM)
  ....
}

Most likely this is what should be written here: m_styBottom == CST_ZOOM || m_styBottom == CST_DELTA_ZOOM.


Ultimate Toolbox

V501 There are identical sub-expressions to the left and to the right of the '&&' operator. UT ox3dtabview.cpp 230


void COX3DTabViewContainer::OnNcPaint()
{
  ....
  if(rectClient.top<rectClient.bottom &&
     rectClient.top<rectClient.bottom)
  {
    dc.ExcludeClipRect(rectClient);
  }
  ....
}

Similar errors can be found in some other places:

  • V501 There are identical sub-expressions to the left and to the right of the '&&' operator. UT oxtabclientwnd.cpp 184

Ultimate Toolbox

V501 There are identical sub-expressions to the left and to the right of the '==' operator: dwDockStyle == dwDockStyle UT oxframewnddock.cpp 190


void COXFrameWndSizeDock::TileDockedBars(
  DWORD dwDockStyle)
{
  ....
  if (pDock != NULL &&
      (pDock->m_dwStyle &&
       dwDockStyle == dwDockStyle))
  ....
}

Probably some other expression should be written instead of "dwDockStyle == dwDockStyle".


Ultimate Toolbox

V501 There are identical sub-expressions to the left and to the right of the '&&' operator. UT oxscrollwnd.cpp 645


void COXScrollWnd::OnPrepareDC(....)
{
  ....
  ASSERT(m_totalDev.cx>=0 && m_totalDev.cx>=0);
  ....
}

This is what should have been written here: ASSERT(m_totalDev.cx>=0 && m_totalDev.cy>=0);

Similar errors can be found in some other places:

  • V501 There are identical sub-expressions to the left and to the right of the '&&' operator. UT oxzoomvw.cpp 179

Fennec Media

V501 There are identical sub-expressions to the left and to the right of the '&&' operator: a -> tsize && a -> tsize media library.c 1076


int fennec_tag_item_compare(struct fennec_audiotag_item *a,
  struct fennec_audiotag_item *b)
{
  int v;
  if(a->tsize && a->tsize)
    v = abs(str_cmp(a->tdata, a->tdata));
  else
    v = 1;
  return v;
}

Notepad++

V501 There are identical sub-expressions to the left and to the right of the '&&' operator: _isPointXValid && _isPointXValid parameters.h 232


bool _isPointXValid;
bool _isPointYValid;

bool isPointValid() {
  return _isPointXValid && _isPointXValid;
};

WinMerge

V501 There are identical sub-expressions to the left and to the right of the '||' operator mergedoc.cpp 1167


BUFFERTYPE m_nBufferType[2];
....
// Handle unnamed buffers
if ((m_nBufferType[nBuffer] == BUFFER_UNNAMED) ||
    (m_nBufferType[nBuffer] == BUFFER_UNNAMED))
  nSaveErrorCode = SAVE_NO_FILENAME;

If we look at the code nearby, the following should be written here by analogy: (m_nBufferType[0] == BUFFER_UNNAMED) || (m_nBufferType[1] == BUFFER_UNNAMED).


eLynx Image Processing SDK and Lab

V501 There are identical sub-expressions to the left and to the right of the '/' operator: sizeof (ms_pfList) / sizeof (ms_pfList) IFF plugins engine.cpp 955


void uteTestRunner::StressBayer(uint32 iFlags)
{
  ....
  static EPixelFormat ms_pfList[] =
    { PF_Lub, PF_Lus, PF_Li, PF_Lf, PF_Ld };
  const int fsize = sizeof(ms_pfList) / sizeof(ms_pfList);

    { BM_GRBG, BM_GBRG, BM_RGGB, BM_BGGR, BM_None };
  const int bsize = sizeof(ms_bmList) / sizeof(ms_bmList);
  ....
}

This is what should have been written here: sizeof(ms_pfList) / sizeof(ms_pfList[0]) and sizeof(ms_bmList) / sizeof(ms_bmList[0]).

Similar errors can be found in some other places:

  • V501 There are identical sub-expressions to the left and to the right of the '/' operator: sizeof (ms_bmList) / sizeof (ms_bmList) IFF plugins engine.cpp 958

eLynx Image Processing SDK and Lab

V501 There are identical sub-expressions 'sizeof (ms_2boolean)' to the left and to the right of the '/' operator. ImageVariant checkformatconversion.cpp 72


void checkFormatConversion::Test(....)
{
  ....
  static struct { bool _b1, _b2; } ms_2boolean[] = {
    { false, false },

    { true,  false },
    { true,  true  }
  };
  const int b2size = sizeof(ms_2boolean) / sizeof(ms_2boolean);
  ....
}

This is what should have been written here: sizeof(ms_2boolean) / sizeof(ms_2boolean[0])

Similar errors can be found in some other places:

  • V501 There are identical sub-expressions to the left and to the right of the '/' operator: sizeof (ms_list) / sizeof (ms_list) ImageVariant checkformatconversion.cpp 99
  • V501 There are identical sub-expressions 'sizeof (ms_ColorSpace)' to the left and to the right of the '/' operator. ImageVariant checkformatconversion.cpp 172
  • V501 There are identical sub-expressions to the left and to the right of the '/' operator: sizeof (ms_bmList) / sizeof (ms_bmList) ImageVariant checkformatconversion.cpp 436

RunAsAdmin Explorer Shim

V501 There are identical sub-expressions to the left and to the right of the '==' operator: luid2.HighPart == luid2.HighPart RAACommon raacommonfuncs.cpp 1511


bool IsLuidsEqual(LUID luid1, LUID luid2)
{
  return (luid1.LowPart == luid2.LowPart) &&
         (luid2.HighPart == luid2.HighPart);
}

This is what should have been written here: (luid1.HighPart == luid2.HighPart).


EchoVNC

V501 There are identical sub-expressions to the left and to the right of the '||' operator: fHorzSize < 0 || fHorzSize < 0 PicLibAPI picture.cpp 347


bool CPicture::Draw(....)
{
  ....
  if (fHorzSize < 0 || fHorzSize < 0 ) {
    return false;
  }
  ....
}

Lugaru

V501 There are identical sub-expressions '(mainmenu && gameon)' to the left and to the right of the '||' operator. Lugaru gamedraw.cpp 2237


int Game::DrawGLScene(void)
{
  ....
  if(freeze||winfreeze||(mainmenu&&gameon)||
     (!gameon&&gamestarted)||(mainmenu&&gameon)||
     (!gameon&&gamestarted)||(!gameon&&gamestarted))
  {
    multiplier=tempmult;
  }
  ....
}

Similar errors can be found in some other places:

  • V501 There are identical sub-expressions '(!gameon && gamestarted)' to the left and to the right of the '||' operator. Lugaru gamedraw.cpp 2237

Lugaru

V501 There are identical sub-expressions '(!gameon && gamestarted)' to the left and to the right of the '||' operator. Lugaru gamedraw.cpp 3960


int Game::DrawGLScene(void)
{
  ....
  if(freeze||winfreeze||(mainmenu&&gameon)||
     (!gameon&&gamestarted)||(!gameon&&gamestarted))
  {
    tempmult=multiplier;
    multiplier=0;
  }
  ....
}

Lugaru

V501 There are identical sub-expressions 'Compare (consoletext [0], "belt ", 0, 4)' to the left and to the right of the '||' operator. Lugaru gametick.cpp 5515


void  Game::Tick()
{
  ....
  if(Compare(consoletext[0],"belt ",0,4)||
     Compare(consoletext[0],"belt ",0,4))
  {
    player[0].skeleton.clothes = 1-player[0].skeleton.clothes;
    donesomething=1;
  }
  ....
}

The word "belt" should start both with the capital and small letters.


TickerTape

V501 There are identical sub-expressions 'm_GamePad [iUserIndex].sThumbLX' to the left and to the right of the '||' operator. TickerTape dxutcamera.cpp 479


void CBaseCamera::GetInput(....)
{
  ....
  if( m_GamePad[iUserIndex].wButtons ||
      m_GamePad[iUserIndex].sThumbLX ||
      m_GamePad[iUserIndex].sThumbLX ||
      m_GamePad[iUserIndex].sThumbRX ||
      m_GamePad[iUserIndex].sThumbRY ||
      m_GamePad[iUserIndex].bLeftTrigger ||
      m_GamePad[iUserIndex].bRightTrigger )
  {
    m_GamePadLastActive[iUserIndex] = DXUTGetTime();
  }
  ....
}

This is what should have been written here: m_GamePad[iUserIndex].sThumbLX || m_GamePad[iUserIndex].sThumbLY ||.


IPP Samples

V501 There are identical sub-expressions 'p_newHeader.pic_parameter_set_id' to the left and to the right of the '!=' operator. h264_spl umc_h264_au_stream.cpp 478


bool H264_AU_Stream::IsPictureSame(
  H264SliceHeaderParse & p_newHeader)
{
  if ((p_newHeader.frame_num !=
       m_lastSlice.frame_num) ||
      (p_newHeader.pic_parameter_set_id !=
       p_newHeader.pic_parameter_set_id) ||
      (p_newHeader.field_pic_flag !=
       p_newHeader.field_pic_flag) ||
      (p_newHeader.bottom_field_flag !=
       m_lastSlice.bottom_field_flag)
      ){
      return false;
  }
  ....
}

The code is formatted. That's why the error is clearly seen. In reality, such errors are difficult to find. 'p_newHeader' is used in two places instead of 'm_lastSlice' here.

Similar errors can be found in some other places:

  • V501 There are identical sub-expressions 'p_newHeader.field_pic_flag' to the left and to the right of the '!=' operator. h264_spl umc_h264_au_stream.cpp 479

IPP Samples

V501 There are identical sub-expressions to the left and to the right of the '<' operator: (m_cur.AcRate [2]) < (m_cur.AcRate [2]) me umc_me.cpp 898


void MeBase::MakeVlcTableDecision()
{
  ....
  Ipp32s BestMV =
    IPP_MIN(IPP_MIN(m_cur.MvRate[0],m_cur.MvRate[1]),
                    IPP_MIN(m_cur.MvRate[2],m_cur.MvRate[3]));
  Ipp32s BestAC =
    IPP_MIN(IPP_MIN(m_cur.AcRate[0],m_cur.AcRate[1]),
                    IPP_MIN(m_cur.AcRate[2],m_cur.AcRate[2]));
  ....
}

See the last string. The index at the end should be '3', not '2'. As a result, the error causes the minimum value to be estimated incorrectly at times.


IPP Samples

V501 There are identical sub-expressions '(mBVOPsearchHorBack)' to the left and to the right of the '>' operator. mpeg4_enc mp4_enc_misc.cpp 547


Ipp32s ippVideoEncoderMPEG4::Init(mp4_Param *par)
{
  ....
  i = IPP_MAX(mBVOPsearchHorBack, mBVOPsearchHorBack);
  ....
}

By analogy with the nearby code, the second variable should be mBVOPsearchVerBack instead of mBVOPsearchHorBack. This is the correct code: i = IPP_MAX(mBVOPsearchHorBack, mBVOPsearchVerBack).


IPP Samples

V501 There are identical sub-expressions to the left and to the right of the '-' operator: state->freq - state->freq speech ec_fb.c 250


int ec_fb_GetSubbandNum(void *stat)
{
    _fbECState *state=(_fbECState *)stat;
    return (state->freq-state->freq);
}

Something wrong has been subtracted. I don't know what the code should look like exactly, but this is obviously an error. The function always returns 0.


IPP Samples

V501 There are identical sub-expressions 'm_pContext->m_seqLayerHeader->heightMB' to the left and to the right of the '&&' operator. vc1_dec umc_vc1_video_decoder.cpp 1347


Status VC1VideoDecoder::ResizeBuffer()
{
  ....
  if(m_pContext && m_pContext->m_seqLayerHeader &&
     m_pContext->m_seqLayerHeader->heightMB &&
     m_pContext->m_seqLayerHeader->heightMB)
  ....
}

This is what should have been written here: m_pContext->m_seqLayerHeader->heightMB && m_pContext->m_seqLayerHeader->widthMB.


IT++

V501 There are identical sub-expressions 'mseq1.get_length ()' to the left and to the right of the '==' operator. itpp_mkl sequence.cpp 126


Gold::Gold(const ivec &mseq1_connections,
           const ivec &mseq2_connections)
{
  ....
  it_assert(mseq1.get_length() == mseq1.get_length(),
            "Gold::Gold(): dimension mismatch");
}

This assert never works.


SAGA GIS

V501 There are identical sub-expressions 'pSandInput->Get_NY ()' to the left and to the right of the '==' operator. grid_analysis soil_texture.cpp 180


bool CSoil_Texture::On_Execute(void)

  ....
  if (pSandInput->Get_NX()==pClayInput->Get_NX() &&
      pSandInput->Get_NY()==pSandInput->Get_NY() )
  ....
}

V501 There are identical sub-expressions 'host != buzz::XmlConstants::str_empty ()' to the left and to the right of the '&&' operator. chromoting_jingle_glue iq_request.cc 248


void JingleInfoRequest::OnResponse(....) {
  ....
  std::string host = server->Attr(buzz::QN_JINGLE_INFO_HOST);
  std::string port_str = server->Attr(buzz::QN_JINGLE_INFO_UDP);
  if (host != buzz::STR_EMPTY && host != buzz::STR_EMPTY) {
  ....
}

Most likely this is what should be written here: (host != buzz::STR_EMPTY && port_str != buzz::STR_EMPTY).


Libjingle

V501 There are identical sub-expressions to the left and to the right of the '&&' operator: !has_audio &&!has_audio libjingle_p2p sessionmessages.cc 308

  bool has_video =
    FindContentInfoByName(contents, CN_VIDEO) != NULL;

  if (!has_audio && !has_audio) {

}

This is what should have been written here: if (!has_audio && !has_video) {

      (super->negNsSet != NULL) &&

}

This is what should have been written here: (sub->negNsSet->value == super->negNsSet->value))


Mesa 3D Graphics Library

V501 There are identical sub-expressions 'ir1->operands [0]->type->is_matrix ()' to the left and to the right of the '||' operator. mesa ir_algebraic.cpp 189

void GLAPIENTRY

{
  ....
  else if (width > 0 && height > 0 && height > 0) {

This is what should have been written here: else if (width > 0 && height > 0 && depth > 0) {


Skia Graphics Engine

V501 There are identical sub-expressions 'kKeep_StencilOp == fFrontFailOp' to the left and to the right of the '&&' operator. skia grstencil.h 159

         kAlways_StencilFunc == fFrontFunc &&
         kAlways_StencilFunc == fBackFunc;
}

Here we seem to have several errors at once. Besides the repeating condition, && and || may be mixed up.


EA WebKit

This is what should have been written here: y >= 0 && y < paintingData.height

            || (bMiddle >= aStart && bMiddle <= aEnd)
            || (bEnd >= aStart && bEnd <= aEnd));
}

The (bStart >= aStart && bStart <= aEnd) comparison is repeated twice. I cannot say for sure what should be written instead of this.

This is an interesting example. There is no error here actually. The last blank is not a blank, but a tab. PVS-Studio doesn't distinguish between blanks and tabs, that's why it has generated a false positive. But this false positive has proved to be useful because it's outrageous to compare something to a tab. This is what should have been written here: (*DebugOptionEnd == '\t').
