Symstore.exe not deleting symbols when added with -:NOREFS option
Nicholas Vasile
with the -:NOREFS option so that my Internet facing symbol server does not
store the refs.ptr files on the web server. I don’t want any reference to the
.pdb source location on web server. I am having a problem which seems to be
isolated to the -:NOREFS option. I am using version 6.9.3.113 of symstore.exe
– it has a modified date of 03/20/2008 06:43 PM. I am wondering if the
behavior is by design or a possible bug.
Problem Summary:
Deleting transactions that have been added with the -:NOREFS option fails
and blank refs.ptr files are added to each symbol directory.
Expected results after delete:
Symbol files are deleted from the symbol store
Actual results after delete:
Symbol files are not deleted and blank refs.ptr files are added to each
symbol directory
Steps I used to repro the problem:
1. Add symbols to the store:
C:\Utils >symstore add /f "\\buildserver\c$\documents and settings\nick\my
documents\visual studio 2005\projects\sehterm\*.pdb" /s
\\symbolserver\testsymstore$ /t "Nicks Programs" /v "beta" /c
"TestAddFromIndex" /o /compress /r -:NOREFS

2. My symbol store looks like this after:
C:\Utils >tree \\buildserver\testsymstore$ /F
Folder PATH listing
Volume serial number is 00500041 D4D0:C96D
\\symbolserver\TESTSYMSTORE$.

3. Try to delete symbols from store:

ore$

thought I'd share the response with the board in case someone else runs into
the same problem.
Deletes using transactions are not expected to work if the transactions were
added with the-:NOREFS option because the add transactions do not
create/update the refs.ptr file for each .pdb. If there were no entries
added/created in the refs.ptr files for an add transaction then symstore.exe
can not currently figure out whether other transactions reference each .pdb
included in the transaction when you try to delete that transaction so they
are not deleted.
The other anomoly I noticed in that a blank refs.ptr file is added as part
of the delete transaction can be considered a minor bug.
