* Add a flag that reports the existence of a dump, and does nothing else.Doug Barton2003-09-042-4/+32
| | | | | | | | | | | The immediate purpose for this option is to use it in rc.d so that we can make savecore behavior conditional. Tremendous assistance with ideas and sanity checking provided by tjr and b@etek.chalmers.se. Notes: svn path=/head/; revision=119734

* - revert back to vmcore.#Bill Fenner2002-05-053-109/+271
| | | | | | | | | | | | | | | | | - reimplement -z - use syslog() - improve consistancy of messages - allow -f to recover cleared dumps - return bufsize to 1024 * 1024 - return the ability to write sparse files - update man page - fix minfree to require 2k for info file instead of the kernel size - include Berkeley copyright too due to amount of old code copied Submitted by: Chad David <davidc@acns.ab.ca> Notes: svn path=/head/; revision=96049

* High-level changes (user visible):Marcel Moolenaar2002-04-131-56/+137
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Implement -c (clear) to clear previously kept headers (note that dumps not cleared will remain until -c is used), o Implement -f (force) to allow re-saving a previously saved dump, o Implement -k (keep) and make clearing the dump header the default, o Implement -v (verbose) and make most output conditional upon it, o Emit minimal output for the non-verbose case with the assumption that savecore is run mostly from within /etc/rc, o Update usage message to reflect what is and what's not, o mark -d as obsolete. Low-level changes: o Rename devname to device, for devname mirrors a global declaration and GCC 3.x warns about it, o Open the dump device R/W for clear and !keep to work, o Reorder the locals of DoFile according to style(9), o Remove newlines from strings passed to warn* and err*, o Use stat(2) to check if a dump has been saved before, o Truncate existing core and info files to support force, o First check for the magic and the version before we complain about parity errors. This prevents emitting parity error messages when there's no dump, o Keep track of the number of headers found and the number of headers saved to support the minimal output, o Close files we opened in DoFile. Not critical, but cleaner. Notes: svn path=/head/; revision=94580

| | | | | | | | | | | | | Commandline compatible with the previous savecore unless you specify any options, none of them are implemented (yet). Scans all devices marked "dump" or "swap" for dump header signatures and saves dumps off under a name which is a MD5 hash of the header information. This should give unique filenames.
