Adding symbols to the symbol store

Bandeep_Singh · August 19, 2004, 10:34am

I am trying to add symbols to the symbol store like this:

C:>symstore add /r /f “C:\Share\4.1.2.9\free\mydriver.pdb” /s c:\Symbols /t
“My Driver” /v “Version 4.1.2.9”
Finding ID… 0000000002

SYMSTORE: Number of files stored = 1
SYMSTORE: Number of errors = 0
SYMSTORE: Number of files ignored = 0

This succeeds and I see it in the store:

C:\Symbols>dir /S mydriver.pdb
Volume in drive C has no label.
Volume Serial Number is DC91-F8CE

Directory of C:\Symbols\mydriver.pdb

08/19/2004 06:56p

Total Files Listed:

5 Dir(s) 4,979,998,208 bytes free

In WinDbg, I verify the sys file timestamp as:

kd> lm t v

Add /v switch to symchk command to turn vebose output to see what’s failing.

I don’t know for sure that this is wrong, but
I usually have two things in my path, the
MS symbol store, with a local cache and my own symbol
store (someplace different than the MS symbol cache.)

I’m not sure the cache is the same structure as a symbol
store.

I would suggest the following for your symbol path:

SRV*C:\MsCachedSymbols*http://msdl.microsoft.com/download/symbols;SRV\*C:\symbols

You need to add the driver file “mydriver.sys” to the symbol store as well.
It can’t look up the pdb file without having access to the sys file.

C:>symstore add /r /f “C:\Share\4.1.2.9\free\mydriver.sys” /s c:\Symbols /t
“My Driver” /v “Version 4.1.2.9”

Hi Andreas,

You need to add the driver file “mydriver.sys” to the symbol store as
well.
It can’t look up the pdb file without having access to the sys file.

C:>symstore add /r /f “C:\Share\4.1.2.9\free\mydriver.sys” /s c:\Symbols
/t
“My Driver” /v “Version 4.1.2.9”

Yes, thank you, that works.

However, why is it necessay? It only eats up the disk space. Can’t WinDbg
identify the symbol file from the loaded modules?

Thanks,
Bandeep

Hi Joseph,

Thanks for replying. Please see inline:

I don’t know for sure that this is wrong, but
I usually have two things in my path, the
MS symbol store, with a local cache and my own symbol
store (someplace different than the MS symbol cache.)

I’m not sure the cache is the same structure as a symbol
store.

I would suggest the following for your symbol path:

SRV*C:\MsCachedSymbols*http://msdl.microsoft.com/download/symbols;SRV\*C:\sym
bols

– Joseph

This isn’t an issue. Cache is pretty much the same as the symbol store; it
works if I ass .sys also as Andreas suggested. However, I am trying to
understand why do we need to add .sys file.

Thanks,
Bandeep

If you are debugging a minidump, minidumps do not have full image header
information for retrieving the correct matching symbol file. So the original
image has to be consulted. See the “-i ” option on the debugger
and the “Using SymSrv” section in debugger.chm.

Occasionally when debugging kernel mode, I have seen image headers partially
paged out, and if the debugger can locate just enough information in memory,
the image can be located so that the right, exact-match PDB gets loaded from
the symbol store. So sometimes when debugging live kernel mode or kernel
mode dumps, the -i option is also useful. Worst case, I think, is that by
specifying -i you might get stacks where you couldn’t before.

Note you can add symbols and binaries into the same symbol store. The
symbol store can store all files you want indexed into the same symbol tree,
and there should never be any collisions.
