Deprecation

This page collects stuff that is considered to be deprecated (and is about to be removed)

Current plan

Per-pid fdinfo.img file

The new layout (marked with respective bit in inventory) is per-fdtable-id

Per-pid file locks

Now all locks sit in the file-locks.img file

Per-pid rlimits, itimers and posix_timers image file

Now all this stuff sit in the core entry

The criu exec action

Should be deprecated with Compel

The --namespaces option

It was used when we didn't have /proc/pid/ns stuff, now it's useless (will be deprecated in 2.2)

Per-PID logs

Not sure whether anybody is using it

Old page-read

Used at ancient times when no pagemaps existed. Can be dropped.

No file records for ttys

See collect_one_tty(). Older versions of criu didn't have reg_file_entry for ttys.

Already deprecated stuff

The criu show action

Deprecated in 2.0 with CRIT

No ids.img files

We've been writing these files since at least v0.4 (deprecated since 2.1)
