* python/qmp-shell: relicense as LGPLv2+John Snow2022-04-211-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qmp-shell is presently licensed as GPLv2 (only). I intend to include this tool as an add-on to an LGPLv2+ library package hosted on PyPI.org. I've selected LGPLv2+ to maximize compatibility with other licenses while retaining a copyleft license. To keep licensing matters simple, I'd like to relicense this tool as LGPLv2+ as well in order to keep the resultant license of the hosted release files simple -- even if library users won't "link against" this command line tool. Therefore, I am asking permission from the current authors of this tool to loosen the license. At present, those people are: - John Snow (me!), 411/609 - Luiz Capitulino, Author, 97/609 - Daniel Berrangé, 81/609 - Eduardo Habkost, 10/609 - Marc-André Lureau, 6/609 - Fam Zheng, 3/609 - Cleber Rosa, 1/609 (All of which appear to have been written under redhat.com addresses.) Eduardo's fixes are largely automated from 2to3 conversion tools and may not necessarily constitute authorship, but his signature would put to rest any questions. Cleber's changes concern a single import statement change. Also won't hurt to ask.

* python: support recording QMP session to a fileDaniel P. Berrangé2022-02-231-7/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running QMP commands with very large response payloads, it is often not easy to spot the info you want. If we can save the response to a file then tools like 'grep' or 'jq' can be used to extract information. For convenience of processing, we merge the QMP command and response dictionaries together: { "arguments": {}, "execute": "query-kvm", "return": { "enabled": false, "present": true } } Example usage $ ./scripts/qmp/qmp-shell-wrap -l q.log -p -- ./build/qemu-system-x86_64 -display none Welcome to the QMP low-level shell! Connected (QEMU) query-kvm { "return": { "enabled": false, "present": true } } (QEMU) query-mice { "return": [ { "absolute": false, "current": true, "index": 2, "name": "QEMU PS/2 Mouse" } ] } $ jq --slurp '. | to_entries[] | select(.value.execute == "query-kvm") | .value.return.enabled' < q.log false Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Daniel P.

* python: introduce qmp-shell-wrap convenience toolDaniel P. Berrangé2022-02-231-4/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the current 'qmp-shell' tool developers must first spawn QEMU with a suitable -qmp arg and then spawn qmp-shell in a separate terminal pointing to the right socket. With 'qmp-shell-wrap' developers can ignore QMP sockets entirely and just pass the QEMU command and arguments they want. The program will listen on a UNIX socket and tell QEMU to connect QMP to that. For example, this: # qmp-shell-wrap -- qemu-system-x86_64 -display none Is roughly equivalent of running: # qemu-system-x86_64 -display none -qmp qmp-shell-1234 & # qmp-shell qmp-shell-1234 Except that 'qmp-shell-wrap' switches the socket peers around so that it is the UNIX socket server and QEMU is the socket client. This makes QEMU reliably go away when qmp-shell-wrap exits, closing the server socket. Signed-off-by: Daniel P.
