How to disable explicitly named exceptions in cdb

问题:

The sx family of commands accept either the name of the exception/event, like av, the exception code or *.

The thing is that * catches all the unnamed exceptions. What if I want to execute a command when any exception happens, be it explicitly named or not?

For instance,

sxe -c "bla-bla-bla" -c2 "ku-ku-ku" av
sxe -c "bla-bla-bla" -c2 "ku-ku-ku" dz
sxe -c "bla-bla-bla" -c2 "ku-ku-ku" *

Instructs the debugger to:

  • execute bla-bla-bla command on the first chance Access Violation
  • execute ku-ku-ku command on the second chance Access Violation
  • execute bla-bla-bla command on the first chance Division by Zero
  • execute ku-ku-ku command on the second chance Division by Zero
  • execute bla-bla-bla command on any unnamed first chance exception
  • execute ku-ku-ku command on any unnamed second chance exception

But, there are about two dozens of the named exception and if I want these commands to be executed on each one of them I seem to be expected to repeat the same sxe statement for each of these exceptions, changing just the exception name.

Is there a better way to do it?

Thanks.

EDIT1

Here is the actual CDB script, where I use the commands:

as AdpDumpDir C:\Logs\Crash

I am looking for ways to make it shorter and simpler, if possible.

As far as I know, there is no nice solution, but you can use this hack:

.foreach(code {sx}) {.catch{sxe -c "bla-bla-bla" -c2 "ku-ku-ku" ${code}}}

where {sx} list all named exception codes and their settings (which will be skipped later). code is just the name of a variable. .foreach(...) {...} processes the output as single words. sxe ... ${code} performs the expected command and .catch{...} ignores all errors (i.e. skips unwanted tokens).

With PyKD you can write a Python script which does it a bit more straight-forward:

from pykd import *

str = dbgCommand("sx")
lines = str.split("\n")
for line in lines:
    if ("-" in line) and not("Command:" in line):
        code = line.split("-")[0].strip()
        dbgCommand("sxe -c \"bla-bla-bla\" -c2 \"ku-ku-ku\" " + code)
