(Tcl) Using DebugLogFilePath to Debug a Crash

If a crash is suspected to occur within a Chilkat method call, it can be debugged using the VerboseLogging and DebugLogFilePath as shown here.

# If a crash is suspected to occur within a Chilkat method call, it can be debugged using the VerboseLogging and DebugLogFilePath as shown here.
# 
# NOTE: The same technique applies for any Chilkat class that has the DebugLogFilePath property.
# Most Chilkat classes have DebugLogFilePath.

set crypt [new_CkCrypt2]

# First make sure VerboseLogging is turned on.
CkCrypt2_put_VerboseLogging $crypt 1

# Set the DebugLogFilePath to the path of a log file that will be created automatically.
# If the file already exists, Chilkat will append to it.
CkCrypt2_put_DebugLogFilePath $crypt "c:/someDir/debugLog.txt"

# Reproduce the problem.

# ...
set success [CkCrypt2_VerifyP7M $crypt "c:/someDir/someFile.p7m"]
# ...

# If a crash occurred within Chilkat, then the debugLog.txt will contain information that
# can be sent to support@chilkatsoft.com

# ------------------------------------------------------------------------------------------------
# Note: Given that the debug log file is always appended, the log file might grow 
# to a very large size.  You can prevent the continual growth of the log file by
# deleting the log file at certain points, such as after a Chilkat method returns.
# 
# Given that we're only interested in the log file for Chilkat calls that crash or hang,
# it's OK to delete the log file after a Chilkat method that returns.
# 
# The next call to a Chilkat method will re-create the log file.  If the Chilkat call crashes
# or hangs, then you'll be left with just the log of the crash or hang.
