- Updating to upstream release 1.2.4
  * Release Notes:
- Preparing for upstream release 1.2.4.
  + Release Notes from upstream:
- There is now much more robust treatment of processes that rapidly
    create and destroy threads.  This was the case for the Java JVM
    (both for OpenJDK and Oracle (Sun) Java).  This was also the case
    for Cilk.  Cilk++ was not tested.  We believe this new DMTCP to now be
    highly robust -- and we would appreciate receiving a notification if
    you find a Java or Cilk program that is not compatible with DMTCP.
- Zero-mapped pages are no longer expanded and saved to the DMTCP checkpoint
    image.  For Java programs (and other programs using zero-mapped
    pages for their allocation arena or garbage collecotr), the checkpoint
    image will now be much smaller.  Checkpoint and restart times
    will also be faster.
- DMTCP_ROOT/dmtcp/doc directory added with documentation of some
    DMTCP internals.  architecture-of-dmtcp.pdf is a good place to
    start reading for those who are curious.
- The directory of example modules was moved to DMTCP_ROOT/test/module.
    This continues to support third-part wrappers around system calls,
    can registering functions to be called by DMTCP at interesting times
    (like pre-checkpoint, post-resume, post-restart, new thread created, etc.).
- This version of MTCP (inside this package) should be compatible with
    the checkpoint-restart service of Open MPI.  The usage will be
    documented soon through the Open MPI web site.  As before, an alternative
    is to simply start Open MPI inside DMTCP, and let DMTCP treat all of
    Open MPI as a "black box" that happens to be a ditributed computation
- A new --prefix command line flag has been added to dmtcp_checkpoint.
    It operates similarly to the flag of the same name in Open MPI.
    For distributed computations, remote processes will use the prefix
    as part of the path to find the remote dmtcp_checkpoint command.
    This is useful when a gateway machine has a different directory
    structure from the remote nodes.
- configure --enable-ptrace-support now uses ptrace module (more modular code).
    The ptrace module should also be more robust.  It now fixes some
    additional cases that were missing earlier
- ./configure --enable-unique-checkpoint-filenames  was not respecting
    bin/dmtcp_checkpoint --checkpoint-open-files .  This is now fixed.
- If the coordinator received a kill request in the middle of a checkpoint,
    the coordinator could freeze or die.  This has now been fixed, with
    the expected behavior:  Kill the old computation that is in the
    middle of a checkpoint, and then allow any new computations to begin.
- dmtcp_inspector utility was broken in last release; now fixed
- configure --enable-forked-checkpoint was broken in the last release.
    It is fixed again.
- Many smaller bug fixes.

* 1.2.2 release notes from upstream:
- A new module system, allowing users to write their own extensions to DMTCP,
  including wrappers around library calls. See the module subdirectory for
  examples.
- ./configure --enable-m32 was not working in DMTCP 1.2.1. It works again now.
- more bug fixes and robustness testing. Tested on kernels ranging from Linux
  2.6.5 to the latest kernel. Tested especially on the Linux distributions: Red
  Hat/Fedora, Debian/Ubuntu, SuSe/OpenSUSE; although we don't know of any Linux
  distributions where it fails to run.
- 'screen' did not checkpoint properly on machines using LDAP authentication.
  This could also affect processes using 'bash'. This has been fixed.
- Furthermore, recent versions of 'screen' began calling 'utempter' when
  present Support for 'utempter' and some other setuid processes has been
  added.
- Removed the requirement for libc.a in building DMTCP, since Red Hat does not
  include libc.a in its standard repository.
- ./configure --enable-ptrace now more robust. Still labelled "experimental"
  for this release. You will need to enable this if you want to checkpoint gdb
  sessions, programs running under strace, and certain other applications.
- ./configure --enable-fast-ckpt-restart can make ckpt/restart faster by using
  'mmap'. You will need to set the environment variable DMTCP_GZIP to "0" if
  you use this. This feature is still experimental, and there are many other
  tricks for speeding up ckpt/restart. Please talk to the developers if this is
  important for your application.
- Experimental support added for HBICT ( hbict.sf.net ). This provides support
  for incremental and differential checkpointing. However, this is still
  ongoing work.
- Work has begun on improved support for process migration between different
  Linux kernels and distributions. Simple applications should migrate. Please
  talk to us if this feature is important to you.
- We do not yet support the 'epoll' and 'inotify' Linux system calls. Recently,
  there has been some demand for this, and we intend to raise the priority.
  Please talk to us if this feature is important to you.
