Symbol path srv microsoft

The following command appends the public symbol store to your existing symbol path:. If local symbol cache location is omitted, the sym subdirectory of the debugger installation directory will be used. Use the. This example shows how to use symfix to create a local symbol cache and use the Microsoft http symbol server. For more information about working with symbols, see the Symbol path for Windows debuggers.

The Microsoft Symbol Server provides compressed versions of the symbol files. For more syntax options, see Advanced SymSrv Use. Microsoft has a Web site that makes Windows symbols publicly available.

You can refer directly to this site in your symbol path in the following manner:. For more information, see Microsoft Public Symbols. If you plan to create a symbol store, configure a symbol store for web HTTP access, or write your own symbol server or symbol store, see Custom Symbol Stores and Symbol Servers.

Any symbol files downloaded by SymSrv will remain on your hard drive after the debugging session is over. Your article hinted me on how to do it even though the stack is clearly incorrect, which means the debugger was right in the first place. General question. Does the symbol paths order matter? Sometimes stepping F10 thru an app in WinDbg is painfully slow even if all symbols paths are correct and symbols are loaded.

I have an impression that WinDbg is spending much time digging into the Windows system symbols. Is there a way telling WinDbg to reduce the scope of symbols matching to speed it up?

Debugging using Windbg : Symbols loading on February 8, Setting symbol path To use the symbols for debugging, we need to tell windbg which directories it should look into, to find the symbols.

Thanks a lot!! Finally-the symbols have been loaded and everything works :. Murad July 27, , pm. If DownstreamStore specifies a directory that does not exist, SymStore will attempt to create it.

If the DownstreamStore parameter is omitted and no extra asterisk is included -- in other words, if you use srv with exactly one asterisk or symsrv with exactly two asterisks -- then no downstream store will be created. The debugger will load all symbol files directly from the server, without caching them locally. If no downstream store is specified, one will be created in the sym subdirectory of the home directory. If a downstream store is used, the debugger will first look for a symbol file in this store.

If the symbol file is not found, the debugger will locate the symbol file from the specified Server and Share , and then cache a copy of this file in the downstream store.

The symbol server does not have to be the only entry in the symbol path. If the symbol path consists of multiple entries, the debugger checks each entry for the needed symbol files, in order from left to right , regardless of whether a symbol server or an actual directory is named. Here are some examples. In addition, the symbol path can contain several directories or symbol servers, separated by semicolons. This allows you to locate symbols from multiple locations or even multiple symbol servers.

If a binary has a mismatched symbol file, the debugger cannot locate it using the symbol server because it checks only for the exact parameters.

However, the debugger may find a mismatched symbol file with the correct name, using the traditional symbol path, and successfully load it.

Even though the file is technically not the correct symbol file, it might provide useful information.

If you are using a DownstreamStore as a cache, you can delete this directory at any time to save disk space. It is possible to have a vast symbol store that includes symbol files for many different programs or Windows versions. If you upgrade the version of Windows used on your target computer, the cached symbol files will all match the earlier version. These cached files will not be of any further use, and therefore this might be a good time to delete the cache.

You can specify any number of downstream stores, separated by asterisks. These stores are known as cascading symbol stores.
