Replaying big logfiles? #686

Open SVABSE opened 10 years ago

SVABSE commented 10 years ago

Hello,

I have som logdata recorded during a whole day running a CAN-system resulting in up to 5 logfiles of size 50MB. Replaying one of this files is no problem. But when collecting all files in a single big file for replay Windows reports "Unhandled exception" . I guess the file (appr. 250MB) is to big. Is there a way to replay the recorded 50MB files sequentially?

Thanks in advance! Regards

First of all an unhandled exception should not occur. This is something we have to fix.

To replay multiple log files in a sequence is an interesting feature request that we should think about. Currently it's not implemented.

I did some more investigation on replaying big log files. I don't know what the size limit of a logfile for replay is (might depend on physical memory) but an "File to big" information before data parsing starts would be great.

An implementation of a progress bar for the data parsing process should be available.

When loading a file that is "to big" to be replayed, busmaster seems to complete the load process. Data on the CAN-bus is displayed in the message window but there is no data being replayed.

The data parsing process takes very long time. To load a 50MB logfile from HDD takes 1.5 min on an ordinary one year old laptop. Would be nice to get it accelerated if possible.

I tried to attach the dump file of an unhandled exception as reported earlier. When it happened I tried to replay two log files of size 100MB each. The memory consumption according to the Windows task manager reached above 80% of physical memory. If you like to receive the dumpfile please provide me with an eMail address.
