DLT converting/resorting/reordering

[DmitryAstafyev]

As soon as we cannot (better - should not) touch an original content of the file, would be useful to have a converter, which can create the new file based on some conditions.

For example for DLT file it can be:

• sorting by timestamp
• cut some content (for example removing some APPID)

The possible workflow could be:

• user opens the original DLT file
• user selects "convert"
• in dialog user select: a) output - like DLT, text; b) some parameters like - sort by timestamp, cut some content and so on

After chipmunk creates a new file based on user inputs and reopens it in a new tab.

Use case 1. Highly relevant for ECU log analysis

Input:

• DLT file or a .pcapng file with potentially a few lifecycles of an ECU

Current situation:

• messages in the log are sorted by reception timestamp / timestamp from the storage header
  • this might be not in line with the DLT timestamp (generation time)

Useful behavior:

• users want to sort the events by the sequence, in which these happen
  • this means sorting by DLT timestamp, but in a "smart" way
    • at the same time this ordering should be local (lifecycle of the ECU shall be detected and sorting shall happen keeping lifecycles intact)
• ideally this happens in place, but the aforementioned "converters" that open a new tab will be also OK
