PVS-Studio Release History

PVS-Studio 4.54 (February 1, 2012)

  • New trial mode was implemented. As of now only a total number of clicks on messages will be limited. More details can be found in our blog or documentation.
  • New menu command "Disable Incremental Analysis until IDE restart" was added. Sometimes disabling the incremental analysis can be convenient, for instance when editing some core h-files, as it forces a large number of files to be recompiled. But it should not be disabled permanently, only temporary, as one can easily forget to turn it on again later. This command is also available in the system tray during incremental analysis.
  • New diagnostic V602. Consider inspecting this expression. '<' possibly should be replaced with '<<'.
  • New diagnostic V603. The object was created but it is not being used. If you wish to call constructor, 'this->Foo::Foo(....)' should be used.
  • New diagnostic V807. Decreased performance. Consider creating a pointer/reference to avoid using the same expression repeatedly.
  • New article in documentation: "PVS-Studio menu commands".

PVS-Studio 4.53 (January 19, 2012)

  • New command for team work: "Add TODO comment for Task List". PVS-Studio allows you to automatically generate the special TODO comment containing all the information required to analyze the code fragment marked by it, and to insert it into the source code. Such comment will immediately appear inside the Visual Studio Task List window.
  • New diagnostic V599. The virtual destructor is not present, although the 'Foo' class contains virtual functions.
  • New diagnostic V600. Consider inspecting the condition. The 'Foo' pointer is always not equal to NULL.
  • New diagnostic V601. An odd implicit type casting.

PVS-Studio 4.52 (December 28, 2011)

  • Changes were introduced to the .sln-file independent analyzer command line mode. It is now possible to start the analysis in several processes simultaneously, the output file (--output-file) will not be lost. The entire command line of arguments including the filename should be passed into the cl-params argument: --cl-params $(CFLAGS) $**.
  • The "Analysis aborted by timeout" error was fixed, it could have been encountered while checking .sln file through PVS-Studio.exe command line mode.
  • New diagnostic V597. The compiler could delete the 'memset' function call, which is used to flush 'Foo' buffer. The RtlSecureZeroMemory() function should be used to erase the private data.
  • New diagnostic V598. The 'memset/memcpy' function is used to nullify/copy the fields of 'Foo' class. Virtual method table will be damaged by this.

PVS-Studio 4.51 (December 22, 2011)

  • The issue concerning the #import directive when using Clang preprocessor was fixed. #import is supported by Clang differently from Microsoft Visual C++, therefore it is impossible to use Clang with such files. This directive is now automatically detected, and Visual C++ preprocessor is used for these files.
  • 'Don't Check Files' settings used for file and directory exclusions were significantly revised. As of now the folders to be excluded (either by their full and relative paths or my a mask) could be specified independently, as well as the files to be excluded (by their name, extension or a mask as well).
  • Some libraries were added to the default exclusion paths. This can be modified on the 'Don't Check Files' page.

PVS-Studio 4.50 (December 15, 2011)

  • An external preprocessor is being utilized to preprocess files with PVS-Studio. It is only Microsoft Visual C++ preprocessor that had been employed for this task in the past. But in 4.50 version of PVS-Studio the support for the Clang preprocessor had been added, as its performance is significantly higher and it lacks some of the Microsoft's preprocessor shortcomings (although it also possesses issues of its own). Still, the utilization of Clang preprocessor provides an increase of operational performance by 1.5-1.7 times in most cases. However there is an aspect that should be considered. The preprocessor to be used can be specified from within the PVS-Studio Options -> Common Analyzer Settings -> Preprocessor field. The available options are: VisualCPP, Clang and VisualCPPAfterClang. The first two of these are self evident. The third one indicates that Clang will be used at first, and if preprocessing errors are encountered, the same file will be preprocessed by the Visual C++ preprocessor instead. This option is a default one (VisualCPPAfterClang).
  • By default the analyzer will not produce diagnostic messages for libpng and zlib libraries (it is still possible to re-enable them).
  • New diagnostic V596. The object was created but it is not being used. The 'throw' keyword could be missing.

PVS-Studio 4.39 (November 25, 2011)

  • New diagnostics were implemented (V594, V595).
  • By default the analyzer will not produce diagnostic messages for Boost library (it is still possible to re-enable them).
  • Progress dialog will not be shown anymore during incremental analysis, an animated tray icon, which itself will allow pausing or aborting the analysis, will be used instead.
  • New "Don't Check Files and hide all messages from ..." command was added to the output window context menu. This command allows you to filter the messages and afterwards prevent the verification of files from the specified directories. The list of filtered directories can be reviewed in "Don't Check Files" options page.
  • The detection of Intel C++ Compiler integration have been revamped – PVS-Studio will not run on projects using this compiler, it is required to replace the compiler with Visual C++ one.
  • "Quick Filters" functionality was implemented. It allows filtering all the messages which do not meet the specified filtering settings.

PVS-Studio 4.38 (October 12, 2011)

  • Speed increase (up to 25% for quad core computers).
  • "Navigate to ID" command added to the context menu of PVS-Studio window.

PVS-Studio 4.30 (June 23, 2011)

  • The full-fledged support for analyzer's operation through command line was implemented. It is possible to verify independent files or sets of files launching the analyzer from Makefile. Also the analyzer's messages can be viewed not only on screen (for each file), but they also can be saved into single file, which later can be opened in Visual Studio and the regular processing of the analysis' results can be performed, complete with setting up error codes, message filters, code navigation, sorting etc. Details.
  • New important mode of operation: Incremental Analysis. As of this moment PVS-Studio can automatically launch the analysis of modified files which are required to be rebuilt using 'Build' command in Visual Studio. All of developers in a team can now detect issues in newly written code without the inconvenience of manually launching the source code analysis – it happens automatically. Incremental Analysis operates similar to Visual Studio IntelliSence. The feature is available only in Visual Studio 2010. Details.

  • New "Analysis Timeout" option. This setting allows you to set the time limit, by reaching which the analysis of individual files will be aborted with V006 error, or to completely disable analysis termination by timeout.
  • New "Save File After False Alarm Mark" option. It allows to save or not to save a file each time after marking it as False Alarm.
  • New "Use Solution Folder As Initial" option. It defines the folder which is opened while saving the analysis results file.

PVS-Studio 4.16 (April 1, 2011)

  • It is possible now to define a list of files to be analyzed while launching the tool from command line. This can be used, for example, to check only the files which were updated by a revision control system. Details.
  • "Check only Files Modified In" option has been added into tool's settings. This option allows you to define the time interval in which the presence of modifications in analyzed files will be controlled using "Date Modified" file attribute. In other words, this approach would allow for verification of "all files modified today". Details.
