Summary
Bug Fixes
Fixed Windows configuration includes so relative paths resolve from the appropriate configuration directory, and paths are handled consistently when matching files.
Improved detection of repeated configuration files, including recursive and indirect includes, to prevent duplicate processing.
Improved Windows file:// path handling for file-backed environment values, including local drive paths. Initial values and refreshed values now use normalized paths.
Improved Windows file matching and directory detection for more reliable glob results.
The pull request updates Windows glob and configuration-include path handling, and normalizes file-backed environment paths. It also changes integration-test process management, network utilities, platform and build-capability checks, and test readiness behavior.
Changes: Windows path handling
Layer / File(s)
Summary
Glob and include path resolution plugins/in_blob/win32_glob.c, src/config_format/flb_cf_fluentbit.c, src/config_format/flb_cf_yaml.c, tests/integration/scenarios/hot_reload_watch/tests/test_include_identity.py
The Windows glob wrapper updates result bookkeeping and directory checks. Windows configuration includes resolve paths and compare included files case-insensitively. Integration tests cover include cycles and duplicate inclusion.
File-backed environment values normalize Windows drive URIs for initial reads and refreshes. A Windows test checks both reads.
Integration test portability and reliability
Layer / File(s)
Summary
Windows process lifecycle tests/integration/src/utils/fluent_bit_manager.py, tests/integration/tests/test_fluent_bit_manager.py
The manager launches Fluent Bit with Windows console options and uses a helper process for shutdown. Manager tests cover platform-specific startup and shutdown behavior.
Port allocation uses synchronized, platform-specific socket probes. Curl selection checks HTTP/2 support and is used by shared request helpers and tests.
Scenario tests skip unsupported signals, Unix sockets, and shared-listener configurations. TLS teardown and process exit checks account for platform behavior, and OpenTelemetry worker counts are configurable.
Integration scenarios check plugin configuration-property support before running collectd, MQTT, Kafka Schema Registry, and Stackdriver tests.
Test readiness and fixture behavior tests/integration/conftest.py, tests/integration/requirements.txt, tests/integration/scenarios/in_nginx_exporter_metrics/tests/test_plus_schema.py, tests/integration/scenarios/in_opentelemetry/tests/test_in_opentelemetry_001.py, tests/integration/scenarios/networking/tests/test_upstream_timeout.py, tests/integration/scenarios/internal_metrics/tests/test_internal_metrics_tag_records.py, tests/integration/scenarios/internal_metrics/tests/test_internal_metrics_tag_records_badconfig.py, tests/integration/scenarios/processor_content_modifier/tests/test_grouped_logs.py, tests/integration/scenarios/processor_fts/tests/*, tests/integration/scenarios/processor_sql/tests/test_sql_grouped_logs.py, tests/integration/scenarios/storage/tests/*
Tests refine metric polling, timeout assertions, HTTP fixture protocols, and logging setup. The integration dependency updates grpcio, and OpenTelemetry tests wait for accepted records before shutdown.

The blob scanner builds recursive patterns such as C:\logs/*.bin. This loop recognizes only \, so it reconstructs a match as C:\file.bin instead of C:\logs\file.bin. The scanner can miss the intended file or process a different file. The corrected result count now makes this traversal reachable. Normalize the pattern before splitting it, or recognize both separators. (raw.githubusercontent.com)

Update the path-separator check in the `while` loop so it recognizes both `\`
and `/` when splitting the pattern, preserving the full directory prefix when
reconstructing matches such as `C:\logs\file.bin`.

Review comments at @plugins/in_blob/win32_glob.c:
- Line 157: Update the no-match error path in flb_file_glob_start to release the
allocated glob context before returning an error; preserve the existing
successful-search cleanup and return behavior.
Review comments at @src/config_format/flb_cf_fluentbit.c:
- Line 202: Update the include-processing flow around the ctx->root_path and
path join to track each file as active before parsing it, then reject includes
that resolve to an already active file; ensure the active-file state is cleaned
up after parsing completes.
Review comments at @src/config_format/flb_cf_yaml.c:
- Line 594: Canonicalize include file identities consistently before recording
them and before checking them with is_file_included; use the _fullpath
path-resolution flow so direct and wildcard includes of the same file compare as
the same identity, regardless of how the main configuration was opened.
Review comments at @tests/integration/src/utils/fluent_bit_manager.py:
- Around line 317-318: Update stop() to catch subprocess.CalledProcessError and
subprocess.TimeoutExpired from _send_windows_shutdown, then continue through the
existing wait() and _force_stop() shutdown path so cleanup still runs.

⚠️Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Use the same path precedence for direct and wildcard includes.
If both the working directory and the configuration directory contain partials/input.conf, @INCLUDE partials/input.conf selects the working-directory file. The new wildcard join makes @INCLUDE partials/*.conf select the configuration-directory file. The configuration can therefore load two different files where these include forms previously selected the same file. Align the direct and wildcard path-selection rules before resolving file identity. (raw.githubusercontent.com)
