How does application verifier work

When I disabled Application Verifier it went from 20 seconds to 13 seconds. It should not be consuming so much time finding a log filename. It might be better to generate the log filename based on timestamp and process id, that way it doesn't have to do this O n search. The text was updated successfully, but these errors were encountered:. That's a great bug.

Sorry, something went wrong. This bug was also reported in when it was found that enabling App Verifier for the compiler and then building Chrome would cause the build to grind to a halt technically not to a halt, but so slow that it was indistinguishable from stopped :.

So, in addition to harming process creation these files waste disk space. They can be disabled but I think that they should be off by default. The original reporter mentioned having 9 GB of log files. I have heard many other reports of many GB of App Verifier log files.

As a temporary work-around for this issue, disable log generation by running appverif. Solutions are going to be impactful, regardless of which option is chosen, esp. Potentially the simplest solution would be to change the default to no log files. Those who want them can turn them on. Then, improved name generation could be added, for that small number of people who need the log files probably mostly Microsoft internal.

You can also specify if you want the error to be reported multiple times or just once per application run. In your specific situation, since you do not want the debugger to break each time an error is found, you should just check the logging options, along with the 'No Break' radio button, except maybe for the most critical errors the verifier can find for which you might want the debugger to break in order to trace and see what the problem is while you reproduce the issue.

When your options are set properly, you can then close the Application verifier application settings will be saved to the registry , and launch your application from Visual Studio.
