2016-06-17vmstate-static-checker: fix size mismatch detection in unused fieldsAmit Shah
If a field changed from something to unused, the checker wasn't flagging if the field size mismatched. This was noticed in: http://thread.gmane.org/gmane.comp.emulators.qemu/419802 where the 4->1 size change along with field name change to 'unused' wasn't being flagged. Fix this.

Commit 8304402033e8dbe8e379017d51ed1dd8344f1dce changed the name of the e1000-82540em device to e1000.

2014-08-04checker: ignore fields marked unusedAmit Shah
While comparing qemu-1.0 json output with qemu-2.1, a few fields got marked unused. These need to be skipped over, and not flagged as mismatches. For handling unused fields, the exact number of bytes need to be skipped over as the size of the unused field. Currently, only the term "unused" is matched. When more field names turn up, this will have to be updated based on the whitelist matching method to match more such terms. Signed-off-by: Amit Shah <amit.shah@redhat.com>

2014-07-16vmstate static checker: detect section renamesAmit Shah
Commit 292b1634 changed the section name of "ICH9 LPC" to "ICH9-LPC", and that causes the static checker to flag this: Section "ICH9 LPC" does not exist in dest This patch introduces a function that checks for section renames and also a dictionary that maps those renames. Reported-by: "Dr. David Alan Gilbert" <dgilbert@redhat.com> Signed-off-by: Amit Shah <amit.shah@redhat.com> --- This is a small patch to a script; doesn't break qemu and helps with the static checker, so it's a very low-risk patch for 2.1.
2014-06-23vmstate-static-checker: script to validate vmstate changesAmit Shah
This script compares the vmstate dumps in JSON format as output by QEMU with the -dump-vmstate option. It flags various errors, like version mismatch, sections going away, size mismatches, etc. This script is tolerant of a few changes that do not change the on-wire format, like embedding a few fields within substructs. The script takes -s/--src and -d/--dest parameters, to which filenames are given as arguments. Example: (in a qemu 2.0 tree): ./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate qemu-2.0.json (in a qemu 2.2 tree:) ./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate -M pc-i440fx-2.0 \ qemu-2.2-m2.0.json ./scripts/vmstate-static-checker.py -s qemu-2.0.json -d qemu-2.2-m2.0.json The script also takes a --reverse parameter to switch the src and dest jsons. This is just a shorthand for reversing the src and dest. The --help parameter shows usage information.
