We are getting close to releasing a new version of the BOINC client software. Not only does the new version contain a bunch of fixes for the client itself, but it also includes new version of the DLLs required by the BOINC Windows Runtime debugger.
It wasn’t always referred to as the BOINC Windows Runtime Debugger; we used to just refer to it as the stackwalker technology. Over the last couple of weeks I’ve made significant changes to the infrastructure on the Windows platform that I feel we can call it something different.
Here is a list of additions that I think will help out:
- Module list dump including location, file versions, and the type of symbols detected.
- Register dump for each thread.
- Stack dumps for each thread.
- Use of Microsoft’s Symbol Store technology.
Upgrading to the latest version of Microsoft’s debugger technology vastly increased the accuracy of the stack traces on Windows when the correct symbol files can be found. Another huge benefit is the use of the symbol store technology.
Symbol stores are basically websites that contain compressed versions of the symbol files. Now for those who have not been following my previous posts the symbol files are pretty big. R@H for instance had a symbol file that was 30MB uncompressed. Now when a crash occurs the debugger will attempt to go to the symbol stores that are defined in the search path and download the correct symbol file for the application. This is a huge win for a project since the symbol files (PDB) for the application do not need to be included for each workunit. Those who are on dial-up connections will have less to download.
Hopefully we can get the rest of the code written so that projects can maintain there own symbol stores. There are many huge wins with getting this technology enabled within BOINC.
Here is a sample of what the new debugger engine produces:
