[v4,0/8] trace-cmd convert

Message

Tzvetomir Stoyanov (VMware) Nov. 11, 2021, 3:12 p.m. UTC

A new trace-cmd subcommand is introduced:
 trace-cmd convert -i <input file> -o <output file>
The command converts trace file between different versions. There are two
parameters for controlling the type of the output file:
 --file-version < 6 / 7>
 --compression < none / any / name of the desired compression algorithm >

This patch-set depends on:
"trace-cmd fixes and clean-ups" patch set.
"Refactor APIs for creating output handler" patch set.
"Refactor the logic for writing trace data in the file" patch set.
"Trace file version 7 - sections" patch set.
"Trace file version 7 - compression" patch set.

v4 changes:
 - Rebased on top of the latest master.
v3 changes:
- Rebased on top of the latest master.
v2 changes:
 - fixed issues of split and convert commands with some corner cases
