This patch series implements conditional monitoring by introducing an OVSDB
RFC extension with 2 new JSON-RPC methods: "monitor_cond" and
"monitor_cond_update". Specification of this extension is defined in the
ovsdb-server (1) man page.
Monitor2 is now merged into monitor_cond. A monitor_cond session with an empty
condition, will behave exactly like monitor2 and will get update2 notifications
on all rows.
Performance:
JSON cache is enabled only for none-conditional monitoring or true conditons
(explicit or implicit). Table JSON cache is enabled only for none-conditional
tables or for tables with none or true condition.
Tables with conditon with only "==" or "includes" functions, which is the most
common case in conditional monitoring, will track changes according to condition
clauses.
By that we want to achieve insert of new row in O(#clauses) and composing
update notification in O(#cahnges to be sent).
Monior sessions with conditon with funcitons that adre different then boolean
or "=="/"includes", we have no magic to do and we expect that computation will
move from clients side to the server.
v3->v4:
* Enable tracking of changes according to condition's clauses in case of "=="
condition
* Enable table JSON cache for tables with true condition
* Add test for conditional monitoring of multiple tables
* Add remove clause API to ovsdb_idl to allow clients iterative workflow
* flake8 fixes
* On composing update on conditon update use ovsdb_row instead of maintaing
changes list
of ovsdb_monitor_row
* Add condition utilities for clause tracking
v2-v3:
* monitor_cond_update method receives a single json condition
* Support non-monitored columns in condition
* Simplify IDL API for iteratively build condition by client
* Bug fixes
* Style issues
v1->v2:
* Change monitor_cond_change to monitor_cond_update
* monitor_cond_update spec allows now to change monitored columns (unsupported)
* Use new <json-value> as a session ID as a result of monitor_cond_update
command.
* Clarifications in ovsdb-server(1) man page.
* Bug fix in ovsdb_monitor_get_all_rows()
* Fix style issues
Liran Schour (17):
ovsdb: create column index mapping between ovsdb row to monitor row
ovsdb: add conditions utilities to support monitor_cond
ovsdb: allow none monitored columns for condition evaluation
ovsdb: generate update notifications for monitor_cond session
ovsdb: enable JSON cache for none conditional monitored tables
ovsdb-client: support monitor-cond method
ovsdb: enable jsonrpc-server to service "monitor_cond_update" request
lib: add to ovsdb-idl monitor_id
lib: add monitor_cond_update API to C IDL lib
python: move Python idl to work with monitor_cond
tests: add testing for idl conditional monitoring
ovsdb: add FALSE mode for tables with false condition
ovsdb: adjust ovsdb_monitor_changes to hold rows by transaction id XOR
datum
ovsdb: Implement data structure to hold changed rows that matchs
condition's clauses
