2020-05-31python: remove more instances of sys.version_infoJohn Snow
We guarantee 3.5+ everywhere; remove more dead checks. In general, try to avoid using version checks and instead prefer to attempt behavior when possible.

2020-05-31scripts/qmp: Fix shebang and importsJohn Snow
There's more wrong with these scripts; They are in various stages of disrepair. That's beyond the scope of this current patchset. This just mechanically corrects the imports and the shebangs, as part of ensuring that the python/qemu/lib refactoring didn't break anything needlessly.

2019-03-11qmp-shell: fix nested json regressionMarc-André Lureau
Commit fcfab7541 ("qmp-shell: learn to send commands with quoted arguments") introduces the usage of Python 'shlex' to handle quoted arguments, but it accidentally broke generation of nested JSON structs. shlex drops quotes, which breaks parsing of the nested struct. cmd='blockdev-create job-id="job0 foo" options={"driver":"qcow2","size":16384,"file":{"driver":"file","filename":"foo.qcow2"}}' shlex.split(cmd) ['blockdev-create', 'job-id=job0 foo', 'options={driver:qcow2,size:16384,file:{driver:file,filename:foo.qcow2}}'] Replace with a regexp to split while respecting quoted strings and preserving quotes: re.findall(r'''(?:[^\s"']|"(?:\\.|[^"])*"|'(?:\\.|[^'])*')+''', cmd) ['blockdev-create', 'job-id="job0 foo"', 'options={"driver":"qcow2","size":16384,"file":{"driver":"file","filename":"foo.qcow2"}}'] Fixes: fcfab7541 ("qmp-shell: learn to send commands with quoted arguments") Reported-by: Kashyap Chamarthy <kchamart@redhat.com> Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <20190205134926.8312-1-marcandre.lureau@redhat.com> Tested-by: Kashyap Chamarthy <kchamart@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

2017-11-21Use qemu.org domain nameStefan Hajnoczi
The owner of qemu.org has delegated authority to modify DNS records to the QEMU Project. This has allowed us to use the domain name without worries about IP address changes or technical issues disrupting service. The issues described in commit 859389810910f232188675d2f10b15f1aad77660 ("Use qemu-project.org domain name") have therefore been mitigated. This patch switches back to consistently using qemu.org instead of qemu-project.org in documentation, version.rc, and the Windows installer script. The git submodules and SeaBIOS still use qemu-project.org for the time being. This will be fixed in the QEMU 2.12 release cycle.

2017-10-11scripts: Remove debug parameter from QEMUMonitorProtocolEduardo Habkost
Use logging module for the QMP debug messages. The only scripts that set debug=True are iotests.py and guestperf/engine.py, and they already call logging.basicConfig() to set up logging. Scripts that don't configure logging are safe as long as they don't need debugging output, because debug messages don't trigger the "No handlers could be found for logger" message from the Python logging module. Scripts that already configure logging but don't use debug=True (e.g. scripts/vm/basevm.py) will get QMP debugging enabled for free.

2016-03-04qmp-shell: fix pretty printing of JSON responsesDaniel P. Berrange
Pretty printing of JSON responses is important to be able to understand large responses from query commands in particular. Unfortunately this was broken during the addition of the verbose flag in commit 1ceca07e48ead0dd2e41576c81d40e6a91cafefd Author: John Snow <jsnow@redhat.com> Date: Wed Apr 29 15:14:04 2015 -0400 scripts: qmp-shell: Add verbose flag This is because that change turned the python data structure into a formatted JSON string before the pretty print was given it. So we're just pretty printing a string, which is a no-op. The original pretty printer would output python objects. (QEMU) query-chardev { u'return': [ { u'filename': u'vc', u'frontend-open': False, u'label': u'parallel0'}, { u'filename': u'vc', u'frontend-open': True, u'label': u'serial0'}, { u'filename': u'unix:/tmp/qemp,server', u'frontend-open': True, u'label': u'compat_monitor0'}]} This fixes the problem by switching to outputting pretty formatted JSON text instead. This has the added benefit that the pretty printed output is now valid JSON text. Due to the way the verbose flag was handled, the pretty printing now applies to the command sent, as well as its response: (QEMU) query-chardev { "execute": "query-chardev", "arguments": {} } { "return": [ { "frontend-open": false, "label": "parallel0", "filename": "vc" }, { "frontend-open": true, "label": "serial0", "filename": "vc" }, { "frontend-open": true, "label": "compat_monitor0", "filename": "unix:/tmp/qmp,server" } ] } Signed-off-by: Daniel P.

Examples: Separate lines: (QEMU) transaction( TRANS> block-dirty-bitmap-add node=drive0 name=bitmap1 TRANS> block-dirty-bitmap-clear node=drive0 name=bitmap0 TRANS> ) With a transaction action included on the first line: (QEMU) transaction( block-dirty-bitmap-add node=drive0 name=bitmap2 TRANS> block-dirty-bitmap-add node=drive0 name=bitmap3 TRANS> ) As a one-liner, with just one transaction action: (QEMU) transaction( block-dirty-bitmap-add node=drive0 name=bitmap0 ) As a side-effect of this patch, blank lines are now parsed as no-ops, regardless of which shell mode you are in.

2015-05-11scripts: qmp-shell: Expand support for QMP expressionsJohn Snow
This includes support for [] expressions, single-quotes in QMP expressions (which is not strictly a part of JSON), and the ability to use "True", "False" and "None" literals instead of JSON's equivalent true, false, and null literals. qmp-shell currently allows you to describe values as JSON expressions: key={"key":{"key2":"val"}} But it does not currently support arrays, which are needed for serializing and deserializing transactions: key=[{"type":"drive-backup","data":{...}}] qmp-shell also only currently accepts doubly quoted strings as-per JSON spec, but QMP allows single quotes. Lastly, python allows you to utilize "True" or "False" as boolean literals, but JSON expects "true" or "false". Expand qmp-shell to allow the user to type either, converting to the correct type. As a consequence of the above, the key=val parsing is also improved to give better error messages if a key=val token is not provided. CAVEAT: The parser is still extremely rudimentary and does not expect to find spaces in {} nor [] expressions. This patch does not improve this functionality.

2015-04-28iotests: add QMP event waiting queueJohn Snow
A filter is added to allow callers to request very specific events to be pulled from the event queue, while leaving undesired events still in the stream. This allows us to poll for completion data for multiple asynchronous events in any arbitrary order. A new timeout context is added to the qmp pull_event method's wait parameter to allow tests to fail if they do not complete within some expected period of time. Also fixed is a bug in qmp.pull_event where we try to retrieve an event from an empty list if we attempt to retrieve an event with wait=False but no events have occurred.

2014-02-28qmp: Check for returned data from __json_read in get_eventsFam Zheng
When QEMU process aborts and socket is closed, qmp client will not detect it. When this happens, some qemu-iotests scripts will enter an endless loop waiting for qmp events. It's better we raise an exception in qmp.py to catch this and make the test script stop.

2014-02-17QMP: allow JSON dict arguments in qmp-shellStefan Hajnoczi
qmp-shell hides the QMP wire protocol JSON encoding from the user. Most of the time this is helpful and makes the command-line human-friendly. Some QMP commands take a dict as an argument. In order to express this we need to revert back to JSON notation. This patch allows JSON dict arguments in qmp-shell so commands like blockdev-add and nbd-server-start can be invoked: (QEMU) blockdev-add options={"driver":"file","id":"drive1",...} Note that spaces are not allowed since str.split() is used to break up the command-line arguments first.

2013-10-11Use qemu-project.org domain nameStefan Hajnoczi
qemu.org is held by a third-party and no core community contributor has access to the DNS configuration. This leaves the website exposed to outages due to DNS issues or IP address changes. For example, if the web server IP address needs to change we cannot guarantee qemu.org will point to it! The newer qemu-project.org domain name is owned by Anthony Liguori <anthony@codemonkey.ws>. You can confirm this by querying the whois information. Also note that the #qemu IRC channel topic already references qemu-project.org. Short of having a dedicated legal entity to hold the domain name on behalf of the community, qemu-project.org seems like the safest bet. Let's replace references to qemu.org with qemu-project.org. Note that git-submodule(1) does not detect URL changes. The following commands clear out and re-initialize all submodules to ensure you are using the latest URLs: $ git submodule deinit . # you'll be warned if you have local changes $ rm -rf .git/modules # also clear cached .git/ directories $ git submodule update --init Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Message-id: 1381495958-8306-1-git-send-email-stefanha@redhat.com Signed-off-by: Anthony Liguori <aliguori@amazon.com>
