fix(clp-s)!: Do not record the archive range index when log-ordering is disabled.

[gibber9809]

Description

Without log-ordering the archive range index has limited usefulness in that the metadata in the range index can not reliably be associated with specific records in the archive. Currently, we still record the archive range index even when log-ordering is disabled. This could sometimes be useful (e.g. if an archive consists of a single range), but probably isn't worth supporting unless users specifically request it.

This PR is marked "fix" because the archive range index was intended to be an optional section partially because of this situation.

Checklist

• The PR satisfies the contribution guidelines.
• This is a breaking change and that has been indicated in the PR title, OR this isn't a
  breaking change.
• Necessary docs have been updated, OR no docs need to be updated.

Validation performed

• Manually validated that an archive produced with the --disable-log-order flag does not contain a RangeIndex metadata packet.

Summary by CodeRabbit

• Bug Fixes

  • Improved handling of log order recording: metadata fields and archive range closing now occur only when log order recording is enabled, reducing unnecessary operations when disabled.

• Documentation

  • Enhanced the help text for the "disable-log-order" option to clarify it also disables recording the archive range index.

Walkthrough

The changes update the help text for a command line option to clarify its behaviour and modify the JsonParser class so that certain metadata operations and archive range management are only performed if log order recording is enabled. No public interfaces were changed.

Changes

File(s)	Change Summary
components/core/src/clp_s/CommandLineArguments.cpp	Expanded the description for the "disable-log-order" command line option to include archive range index info.
components/core/src/clp_s/JsonParser.cpp	Made metadata field addition and archive range closing conditional on m_record_log_order in two methods.

Learning: In `clp_package_utils/scripts/native/del_archives.py`, when deleting archives, the `archive` variable retrieved from the database is controlled and is always a single string without path components. Therefore, it's acceptable to skip additional validation checks for directory traversal in this context.

Learning: The `creation_idx` field in `ArchiveMetadata` is used for tracking archive order in split archives. When archives aren't split, it can be safely initialized to zero.

🔇 Additional comments (6)

components/core/src/clp_s/JsonParser.cpp (6)

514-516: LGTM - Clean early return pattern implemented correctly.

The conditional check properly implements the intended behavior of skipping metadata operations when log order recording is disabled. The early return approach is efficient and avoids unnecessary work.

---

517-518: LGTM - Variable assignment properly conditional.

The log_event_idx_node_id assignment is correctly placed within the conditional block, ensuring it's only initialized when needed. The variable is properly zero-initialized at declaration (line 512), making this usage safe.

---

661-667: LGTM - Archive range closing properly conditional.

The conditional execution of close_current_range() correctly aligns with the PR objective of not recording archive range index when log-ordering is disabled. The error handling remains intact within the conditional block.

---

986-988: LGTM - Consistent implementation across methods.

The same early return pattern is correctly implemented in parse_from_ir(), maintaining consistency with the changes in the parse() method. This ensures uniform behavior across both parsing paths.

---

989-990: LGTM - Consistent variable handling.

The conditional assignment of log_event_idx_node_id mirrors the pattern used in the parse() method, ensuring consistent behavior. The variable is properly zero-initialized at line 984.

---

1146-1152: LGTM - Consistent range closing implementation.

The conditional closing of the current range matches the pattern established in the parse() method, ensuring consistent behavior across both parsing paths. The error handling is properly maintained within the conditional block.
