Implement 'everything' group behavior
precheck group and node settings
do not create groups or nodes by default
Have httpapi preserve original query in case the plugin modifies it for accurate API
explorer output
Firmware fixes obsolete the need. The bad behavior on older firmware
is sufficiently tolerable that code to workaround that could have bad
side effects can reasonably be abolished.
To do performance optimization in this sort of application, this is
about as well as I have been able to manage in python. I will say perl with
NYTProf seems to be significantly better for data, but this is servicable.
I tried yappi, but it goes wildly inaccurate with this codebase. Because of
the eventlet plumbing, cProfile is still pretty misleading. Best strategy
seems to be review cumulative time with a healthy grain of salt around the
top items until you get down to info that makes sense. For example, trampoline
unfairly gets a great deal of the 'blame' by taking on nearly all the activity.
internal time seems to miss a great deal of important information.
Previously, the state would be seen as 'connected' and then 'disconnected' in event of
connection failing. Rework things such that the console session stays in 'connecting' state
until timeout or success occurs and don't send disconnect, instead raising an exception.
This makes the connection action a bit more intuitive to the user, who would assume a 'connected'
console means the endpoint was reachable. This may not always be possible in a console plugin,
but it's a nice pattern when possible. If a console plugin cannot tell when 'connected' happens, then
the previous behavior of this plugin makes sense as a 'best effort': return 'connected', send
disconnect event when the console turns out to be bad. For example, executable consoles are most
likely going to follow this pattern. An option could be for an executable to have a certain
signature to print to show 'connected' though...
This change causes cfg change notifications to more accurately reflect atomic
expectactions. If multiple fields are changed on multiple nodes that a watcher may
have registered, they will now get that data in one chunk instead of many.
Add ability for code to add watchers on nodes and their attributes. This is likely to
be reworked internally to better aggregate requests, but the code interface
is potentially complete.
It has been expressed that plural form for collection names are preferred. Additionally, tab
completion is nicer if names do not share so much leading characters.
The facility was incorrectly reassembling the text records in reverse order. With this change,
the set buffer from log function seems to be working as intended.
Before, it would delve back to set state if recent entries indicated to not
assert the tracked states. Correct that behavior so only last entry counts.
ESXi requires a distinctly different keypad mode and 'shift in' character set. Track
requests for those states. Reset on 'null' character, which seems to only be emitted by UEFI
so far. Ideally, things change such that we can remove that workaround.
Since the log analysis merely needs to know if a connect/disconnect is redundant,
only report 0, 1, or '2' connections to indicate 2 or greater. log analysis
then would want to seek out a connect with eventdata of '1' and disconnect with
eventdata of '0' and mostly ignore the '2' info. Desire for more data
could be done by actually counting the connects and disconnects, this is
just to provide a fast path to finding the 'first connection' and 'last disconnect'
signatures.
For a log reviewer tool to unambiguously understand whether a given user is conceivably watching,
more data is needed. It doesn't keep track of which disconnect goes with which connection, but
it at least provides a way of detecting whether user is truly disconnected or not.
Implement the bits and pieces that are at least required for conserver like logging.
This has a plaintext file and a binary metadata file. The plaintext file basically
resembles a conserver log, while the binary file facilitates faster seeking to points
of interest with the file and much more precise timestamp information.
'nodepower' is not yet 'rpower' like, but it's a quick
demonstration of using the python confluent client library. It
only supports unix socket as written
The pickling would get horrendously slow as total node count increased. This meant very long time to sync
to disk for just one change out of 65,000. This strategy changes things to more selective and only
do things for the dirty keys rather than everything. Large changes to small amounts of nodes will take
more time (because more calls to dump pickle), but small changes to a small subset of nodes will take much
less time.
There was an optimization to skip examination of groups if it was determined
that the group membership had not changed. However, this erroneously
masked the examination in the case of reordered groups. Skip the
optimization to cover that case at the expense of at least some needless churn.
This only happens when something goes to change group membership in some way, so
this shouldn't be too expensive.
Now when expressions can not be completed, the reason is presented as 'broken'.
Additionally, when unsetting a value that would affect expressions,
perform appropriate changes.
If data was coming in as unicode strings (as is the case in the json
parser), it failed to treat the data as equivalent to string. Correct
by checking both str and unicode for now
A client with certain URLs that go off the end of the valid world was
causing exceptions to be thrown not of the set of 'tame' errors.
Denote them as 404 since that is the nature of the failure.
Provide a means to clear node specific settings so that inheritance can be restored.
In JSON, send a null as a value for a parameter instead of a string or 'object'.
