Introducing negative options for true / false values. The original getopt_long parser is kept since it is able to set flag-like values (instead of setting these values in the switch when it's not needed). The type of the options needed to be changed to integers for getopt_long to accept flag-like value settings (as per getopt_long documentation, the address of integer variable has to be passed). Corresponding negative options are not added for deprecated options. This patch is a preparation for the addition of configuration files (GitHub issue #278). General idea of this feature is to have global configuration files in /etc/criu.d/ directory and user-specific configuration files in $HOME/.criu.d/ directory, with the possibility of specifying a chosen file to be used (default files will be used if none is specified, or none in case the default ones are not present, to not break compatibility). The options in configuration files should be possible to be overriden by the options specified on command line, hence the negative options addition. The whole feature of configuration files will remove the need of specifying all the options on command line, with the possibility of reusing a file for different use case with only overriding some of the values specified there. In case both types of option (negative and positive) are passed, the later one will be applied -- this works with the philosophy of overriding the "earlier" options from configuration files. Changes since v1: - Describe the --no- option prefix in the beginning of OPTIONS section in both man page and --help instead of mentioning it at every eligible line (this also fixes line length issue with --help) - Fix the accidental removal of check_only case caused by bad rebase - Use a macro for getopt_long struct option generating instead of additional defines and hardcoded lines Signed-off-by: Veronika Kabatova <vkabatov@redhat.com> Signed-off-by: Andrei Vagin <avagin@virtuozzo.com> |

CRIU (Checkpoint and Restore in Userspace)
An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.
The project home is at http://criu.org.
Pages worth starting with are:
- Kernel configuration, compilation, etc
- A simple example of usage
- More sophisticated example with graphical app
