- Set recorder to nonblocking when finished

- Fix read_data() from using error value of tracefs_cpu_read() as index

- Return the result of tracefs_cpu_stop() to tracecmd_stop_recording()

trace-cmd: Version 3.1.5

Updates since version 3.1.4:

 - Make build against musl C library

 - Quiet gcc warning of snprintf truncation

 - Quite warnings from libtraceevent and libtracefs by default

 - Fix the -m option where making a max size trace file was broken

 - Add unit test for -m option

 - Make the unit tests depend on the static library to build that
   if anything changes in the library when making the test

 - Let subcommand "convert" automatically compress if possible

libtracecmd: version 1.3

Changes since v1.2.0:

Fixes:

 - Only set trace-cmd log level (not libtracefs nor libtraceevent)

 - Do not call callbacks with a NULL record

 - Build against musl C library

 - Quiet gcc warning on snprintf truncation

 - Fix function graph plugin updating the next record

Core updates:

 - Use libtracefs tracefs_cpu() interface for recording
   (requires libtracefs 1.6)

New API:

 - Add tracecmd_follow_missed_events() to trigger a callback when a missed
   event is discovered in tracecmd_iterate_events()

trace-cmd Debian release 3.1.4-1

trace-cmd: Version 3.1.4

Updates since version 3.1.3:

 - Fix calculation of pipe_size (which defaulted to just page size)

libtracecmd: version 1.2

Changes since v1.1.3:

Fixes:

- Show conter as a counter and not as seconds (for v7 files)

- Fix msg_lseak() prototype

- Fix compression offset handling

- Fix out of bounds in tracecmd_read_data() function

- Use local clock if no clock is defined when creating a instance buffer

- Fix the communication between host/guest agent/recording

- Do no compression when the compression option is "none"

- Various compression fixes

- Various agent fixes

- Clean up the time synchronization code

- Allow time synchronization to happen over the network.

- Make clock source TAI use seconds conversions

- Have trace_msg cache use memfd when available.

- Fail if tracecmd_init_data() fails (and not return success!)

- Verify that splice() works before using it

- Fix mapping of vCPUs as they may not be consecutive in the
  kvm debugfs directory (although they are in the guest)

- Clean ups to the Makefiles

- Allow linking to C++ programs.

New features:

- Add msg PROXY protocol, such that the host can be an agent
  and the guest can be the recorder.

New APIs:

- tracecmd_iterate_events() - easy way to iterate over all events
  in a trace.dat file.

- tracecmd_iterate_events_multi() - easy way to iterate over all
  events in multiple trace.dat files (and if the first one is a
  host file, it will connect them with the other files if the other
  files are guest files).

- tracecmd_set_private() and tracecmd_get_private() - to allow applications
  to associate private data with a tracecmd_input handler.

- tracecmd_filter_add() - To add a filter that affects the above iteration
  functions

- tracecmd_follow_event() - to follow a given event and call a callback function
  when one of the above iterators hit it.

- The following "map" functions for keeping track of vCPUs and the host
  threads that run on their behalf.

	tracecmd_map_vcpus()
	tracecmd_get_cpu_map()
	tracecmd_map_find_by_host_pid()
	tracecmd_cpu_map()
	tracecmd_map_get_host_pid()
	tracecmd_map_get_guest()
	tracecmd_map_set_private()
	tracecmd_map_set_private()

trace-cmd: Version 3.1.3

Updates since version 3.1.2:

 - Fixes to the host/guest agent communication

 - Update to documentation

 - Cleanups to Makefiles

 - Updates to the testing (utest)

 - Convert trace-cmd reead to use some of the library helpers instead
   of open coding it.

 - Have trace-cmd read -F affect the last -i file and not just the first one.

 - Have trace-cmd read use the new tep_plugin_kvm_get_func() callback
   (If the library does not define it, it will simply be ignored).

Minor feature enhancements: (not enough to change the extra version number)

 - Add --notimeout option to allow agend and record to not timeout if
   the other end is doing debugging (via gdb). --debug already does this
   but this option is to not need full debugging, but to just tell the
   other end not to error out on timeout.

 - Add --compression to extract (the feature was there, but the option was not).

trace-cmd: Version 3.1.2

Updates since version 3.1.1:

 - Documenation fixes

 - Better error handling of agent communication for time synchronization.

 - Do not depend on the host debugfs/kvm/<pid>/vcpuX to map one as the same
   value as the guests virtual CPU X, but instead just map them in the order
   they are defined.

 - Fix size value of uncompressed size for s390.

 - Update make-trace-cmd.sh script to use custom CFLAGS.

trace-cmd: Version 3.1.1

Updates since version 3.1.0:

 - Display as seconds (with period) when TSC2NECS flag is set

 - agent proxy: Set clock to TSC when negotiated kvm synchronization.

 - report: Add --first-event and --last-event options to show the first
     and last events of CPUs.

 - Fix up man pages

 - report: Better describe the -l option.

 - record: Add --temp option to store temp files.

 - stat: Show all filtered functions that are enabled (not just a subset)

 - Fix searching of compressed chunks (it was searching in the wrong order)

 - Fix lookup of records in compressed chunks.

 - split: Have missed events in created files

 - stat: Show set_event_notrace_pid entries

 - stat: Show set_ftrace_notrace_pid entries

 - stat: List synthetic events in the system

 - record: Verify that the splice system call works before using it

 - utest: Add unit tests specific for trace-cmd and remove the ones
          that were used for libtracefs.
