procesor_content_modifier: Accept list on configure - #12329
Conversation
📝 WalkthroughWalkthroughContent modifier configuration now accepts multiple keys. Logs, metrics, and traces process each configured key. Native processor properties expand supported arrays into individual assignments. Runtime tests cover multi-key CRUD actions and atomic conversion failures. ChangesContent modifier key configuration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The change adds list-valued keys, but current configuration checks can make those lists appear empty, preventing multi-key operations from running. One conversion regression test can also pass without checking the result when processing fails. This is a bounded correctness and test-readiness issue, so the PR is not merge-ready until the list handling and ineffective assertion are corrected.

Full details: Linked Issues checkExplanation The changes satisfy issue Full details: Out of Scope Changes checkExplanation The pull request implements the linked delete-list objective, but it also adds list support for insert, upsert, hash, and convert actions across logs, metrics, and traces. These additional operations are not required by issue Resolution Limit the pull request to list support for the delete action, or link issues that explicitly require list support for insert, upsert, hash, and convert actions. Keep shared infrastructure only when it is necessary for the delete implementation.

- Around line 29-30: In both key-counting helpers, including cm_key_count(),
reverse the mk_list_is_empty(ctx->keys) condition to recognize non-empty
configured key lists, preserving the existing return behavior so log, metric,
and trace loops process configured actions.

plugins/processor_content_modifier/cm_logs.c lines 256-271 and
plugins/processor_content_modifier/cm_metrics.c lines 242-257 so missing key
lookups are skipped rather than returned as failures; also make the logs
replacement loop skip NULL entries. Preserve conversion for present key-value
pairs and avoid treating absent keys as FLB_PROCESSOR_FAILURE.

- Around line 1231-1243: Update the processor test around cb_check_result so it
cannot pass when the convert action prevents output: add and assert a
callback-invocation counter, or inspect the processed record directly as the
metrics and traces tests do. Preserve the existing foo and bar validation while
ensuring the test explicitly detects whether result checking occurred.

236-293: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winOne staged conversion algorithm is copied into two files. Both implementations allocate the same two arrays, stage every key, skip absent keys, commit, and free identically. They differ only in the kvpair lookup helper. The earlier missing-key fix had to be applied to both copies, which shows the divergence risk.

Implemented list-valued
keysupport forcontent_modifier.Supported list operations:
insertandupsert: reuse the configured value for each key.deletehashconvert: reuse the configured target type.renameandextractremain scalar-only because multi-key semantics are ambiguous.Key changes are in cm.c, cm_config.c, and the processor property loader in flb_processor.c. The behavior applies across logs, metrics, and traces. Regression tests cover delete and upsert lists in processor_content_modifier.c.
Verification:
cmake --build build -j8 --target flb-rt-processor_content_modifier flb-it-processor_conditionalctest --test-dir build -R '^(flb-rt-processor_content_modifier|processor_conditional\.sh|flb-it-processor_conditional)$' --output-on-failureleaks --atExit -- build/bin/flb-rt-processor_content_modifier 'logs.action.delete_key_list'flb_output_task_flush. The unchanged scalar delete test reports the identical leak, confirming no additional feature-specific leak. Strict memory-check status is therefore blocked by that existing runtime-test baseline.processor_content_modifierscenario.Closes #9526.
