rsyslog now accepts .yaml / .yml files as a full alternative to
RainerScript configuration. Whenever a .yaml or .yml file is
referenced (e.g. via $IncludeConfig or as the main config), it is
routed through the new yamlconf loader instead of the bison/flex
parser. RainerScript and YAML configurations may coexist.
Supported top-level sections
global: global settings
main_queue: main queue settings
modules: module loading (load:, params:)
inputs: input objects templates: string, subtree, plugin, and list templates
(including all property/constant modifiers)
rulesets: rulesets with optional script: block (raw
RainerScript), filter/action shortcut (if:/then:),
and the full statements: block:
action:, set:, unset:, call:, call_indirect:,
foreach:, if:, stop:, continue:,
reload_lookup_table:
outputs: output objects (top-level convenience alias)
include: recursive includes (.yaml processed immediately;
.conf files pushed to LIFO stack in reverse order
for correct document-order processing)
Implementation notes
- Thin front-end over existing cnfobj/nvlst/cnfDoObj() machinery;
all parameter validation happens downstream unchanged.
- Script blocks synthesised as RainerScript strings and injected via
cnfAddConfigBuffer() (requires two trailing NUL bytes).
- YAML -> YAML includes are synchronous recursive calls;
YAML -> .conf includes use the flex buffer stack.
- Mixed include lists (.yaml + .conf) emit a warning because strict
document order cannot be preserved across the two mechanisms.
- Built conditionally: --with-libyaml / HAVE_LIBYAML.
Tests
19 new shell tests cover: basic config, modules, inputs, templates
(string/subtree/list with modifiers), rulesets with script/filter/
statements blocks, stop/continue, set/unset, foreach, call,
call_indirect, reload_lookup_table, includes, error handling.
Documentation
doc/source/configuration/yaml_config.rst (new reference page)
Inline comments in yamlconf.c explain all invariants and non-obvious
design choices (es_getBufAddr non-null-termination, LIFO stack
ordering, cnfAddConfigBuffer double-NUL requirement, etc.)

# Tests the property-filter (":"-prefixed) form of the YAML filter: shortcut.
|
|
# A property filter matching on $msg routes messages that contain "msgnum:"
|
|
# to the output file via the actions: shortcut.
|
|
# Complements yaml-filter-actions.sh which tests PRI filters (e.g. *.*).
