Add Otlp Support - #274
Conversation
📝 WalkthroughWalkthroughAdds OTLP trace support for JSON, JSONL, and protobuf inputs. The change introduces span data models, parsers, sorting jobs, Trace Compass integration, Eclipse and Maven wiring, feature registration, span-life analysis updates, and tests for multiple trace sizes. ChangesOTLP trace support
Estimated code review effort: 4 (Complex) | ~75 minutes Merge Risk: 🟠 High · up to This PR adds OTLP file ingestion and changes span-life timestamp handling, but the current head can skip valid JSONL traces, abort or silently lose data on malformed inputs, report incomplete output as successful, and potentially fail analysis lookup; large traces may also exhaust the local process and mixed timestamp writes can violate ordering. Merge should wait for these issues to be fixed or explicitly accepted by the owning team. Sequence Diagram(s)sequenceDiagram

resourceAttributes.deepCopy()runs once per span. Every span in the flat output then carries a full copy of the resource attribute array.OtlpProtobufSortingJobholds all spans in memory before it writes them, so the duplicated attributes multiply peak memory and the size of the supplementary file for large traces.The copy is required only because each span later serializes independently.

Trace Compass TMF analysis extension point module id analysis_module TmfAnalysisModule setId lookup
💡 Result:
In the Eclipse Trace Compass TMF (Trace Metamodel Framework) analysis framework, the analysis module ID is primarily registered via the org.eclipse.linuxtools.tmf.core.analysis extension point [1][2]. 1. Extension Point Registration: When defining an analysis module in your plugin's plugin.xml, you provide a unique string identifier in the id attribute of the module element [1][2]. <module id="my.analysis.id" analysis_module="my.package.MyAnalysisClass"... /> 2. Module ID Usage: The ID defined in the extension point is the primary way the framework identifies and manages the analysis module [1][3]. This ID is used by other parts of the system (such as views or other modules) to interact with the module's outputs or state systems [4][3]. 3. setId Method: The setId(String id) method exists within the IAnalysisModule interface (and its base classes like TmfAbstractAnalysisModule) to programmatically set the module's ID [5][3]. - In most standard plugin-based implementations, the ID is automatically handled by the framework using the value specified in the plugin.xml [1][2]. - You typically call setId only when creating an analysis module manually or dynamically, such as when implementing custom module helpers or parsing XML-based analyses, to ensure the module instance matches the expected ID [5]. 4. Lookup: To look up or retrieve a module's state system or data by its ID, you generally use static helper methods like TmfStateSystemAnalysisModule.getStateSystem(ITmfTrace trace, String moduleId), which resolves the requested ID against the trace's registered analyses [3]. In summary, while the plugin.xml registration is the standard way to declare an ID, setId is used for manual instantiation or specific framework overrides where a module needs to be associated with an existing ID programmatically [5][3].

💡 Result:
In the Eclipse Trace Compass framework, TmfAnalysisModuleHelper serves as a base implementation of the IAnalysisModuleHelper interface [1][2]. It plays a critical role in the analysis framework by managing non-trace-specific metadata and lifecycle operations for analysis modules [1][3]. Key functions and characteristics of TmfAnalysisModuleHelper include: Metadata Management: It stores and provides access to static information about an analysis module, such as its unique identifier (ID), display name, and the specific trace types to which the analysis can be applied [1][3]. Integration with TmfAnalysisManager: The TmfAnalysisManager, a singleton service in Trace Compass, utilizes these helpers to keep track of all available analysis modules across the application [1][3]. Module Instantiation: When a trace is opened, the framework uses these helpers to instantiate the appropriate analysis modules for that trace [1][3]. Extensibility: Developers creating custom analyses or extending existing ones often use or extend these helper classes. For example, the XML analysis framework utilizes TmfAnalysisModuleHelperXml (a subclass) to facilitate the creation and management of XML-defined analysis modules [2]. In practice, if you are defining a new analysis, you typically interact with the analysis framework by providing a helper that the TmfAnalysisManager can register. This architecture allows Trace Compass to dynamically discover, categorize, and execute analyses based on the trace types currently loaded in the system [1][3].

Align the OTLP registration ID with the provider lookup.
The framework replaces the analysis instance ID with the XML id. SpanLifeDataProviderFactory looks up org.eclipse.tracecompass.incubator.opentracing.analysis.spanlife, so it cannot find the OTLP instance registered as org.eclipse.tracecompass.incubator.otlp.analysis.spanlife. Use the shared OpenTracing ID or add an OTLP-specific analysis class and provider ID.

Read OTLP files as UTF-8, not with the platform default charset. Every reader in the OTLP pipeline uses new FileReader(path), which decodes with the JVM default charset. The OTLP JSON specification requires UTF-8. On a platform whose default charset is not UTF-8, non-ASCII span names, service names, and attribute values are corrupted or the parse fails. The shared root cause is the missing explicit charset on all four reader constructions. Pass StandardCharsets.UTF_8 in each, for example new InputStreamReader(new FileInputStream(path), StandardCharsets.UTF_8).

OTLP spans can contain span events (logs) that represent timestamped occurrences within a span. Previously these were only accessible as Jaeger-style logs embedded inside the parent span's event content. Flatten each span event into its own zero-duration synthetic span entry during sorting so that each span event appears as a separate row in the events table. The synthetic entries inherit the parent span's traceId, spanId, serviceName, and resource attributes. For example, a trace with 12 spans and 530 span events now produces 542 TMF events instead of 12.

Spans sorted by start time can have end times that precede the next span's start time, which violates the state system's requirement for monotonically non-decreasing timestamps.

The SpanLifeDataProviderFactory looked up the analysis by the hardcoded SpanLifeAnalysis.ID, which does not match the OTLP analysis module's runtime ID set from its plugin.xml registration. This caused the data provider to never be created for OTLP traces, leaving the Span Life view empty. - Use getAnalysisModulesOfClass (class-based lookup) instead of getAnalysisModuleOfClass (ID-based) in the factory - Return the static ID constant from SpanLifeDataProvider.getId() so it always matches what the view and DataProviderManager expect This patch was made with the assistance of claude sonnet 4.6 Change-Id: If267ef73b0b7aa36df1336bbe7b1f75d40d8be15 Signed-off-by: Matthew Khouzam <matthew.khouzam@ericsson.com>

🌐 Web query:
Java PriorityQueue documentation ties broken arbitrarily official
💡 Result:
Yes, the official Java documentation for the PriorityQueue class explicitly states that tie-breaking is handled arbitrarily [1][2][3]. Specifically, the documentation notes: "If multiple elements are tied for least value, the head is one of those elements -- ties are broken arbitrarily" [1][4]. This means that the PriorityQueue does not provide a guarantee of stable ordering (such as First-In-First-Out) for elements that have equal priority according to the queue's comparator or their natural ordering [5][6]. If your application requires a deterministic order for tied elements, it is standard practice to incorporate a secondary sorting criterion—such as a sequence number, timestamp, or unique ID—into your Comparator or Comparable implementation [5][6][7].

Define a deterministic order for equal-timestamp writes.
DeferredModification.compareTo() compares only timestamp. The clear for one log and the value for the next log can share a timestamp and target the same logQuark. PriorityQueue does not define the order of tied elements, so the clear can overwrite the new value. Order clears before values at equal timestamps, then use a sequence number as the final tie-breaker. Add a regression test for consecutive-nanosecond logs.

Contain type-shape exceptions inside the two public parse methods.
Both methods document a null return for a failed parse, but only JsonSyntaxException from fromJson and the timestamp NumberFormatException are contained. Several accessors throw unchecked exceptions when a field has an unexpected JSON type:
- Line 183
kindEl.getAsInt()and Line 376codeEl.getAsInt()throw whenkindorstatus.codeis a non-numeric string. - Line 484
optStringthrowsUnsupportedOperationExceptionwhenname,traceId, orstartTimeUnixNanois an object or array. - Lines 262, 280, 313, 344, 392, 411 and 438 call
getAsJsonObject()on array elements and throwIllegalStateExceptionwhen an element is a scalar, for example"attributes": ["a"].
OtlpTrace.parseEvent catches IOException only, so one malformed span aborts the whole trace read instead of skipping that span.
Wrap the body of each public method and return null on these exceptions.

Also exclude JsonNull in the parseAttributes key guard.
Line 394 checks keyEl == null only. For {"key": null, ...}, keyEl is JsonNull and Line 397 getAsString() throws UnsupportedOperationException. The three loops in toJaegerJson already check isJsonNull(), so the two paths behave differently for the same input.

checkError() runs before the final flush in both sorting jobs. PrintWriter(File) buffers output, so checkError() cannot see a failure that occurs during the flush performed by close(). close() also swallows the IOException. A full disk therefore produces a truncated supplementary file and Status.OK_STATUS.

Catch IllegalStateException in the single-JSON path too.
extractSpansFromResourceSpans calls getAsJsonObject() on resourceSpans, scopeSpans, and spans elements without a type check. A scalar element, for example "resourceSpans": ["x"], throws IllegalStateException. This catch clause handles JsonSyntaxException and IOException only, so the exception escapes run, which also handles IOException only. The job then fails with an unhandled exception instead of the JSONL fallback or an error status. tryParseJsonl already catches IllegalStateException at Line 166.

Fix the inverted null check that disables the whole JSONL path.
Line 158 returns early for every successfully parsed line. root != null is the success case, so continue skips extraction for all valid JSONL lines and allSpans stays empty. run then returns "No spans found in OTLP trace" for every JSONL trace.
The remaining path is also unsafe. Execution reaches Line 161 only when root is null, which Gson returns for a line containing the null literal. root.getAsJsonArray(...) then throws NullPointerException. The catch clause lists JsonSyntaxException and IllegalStateException only, so the exception escapes tryParseJsonl and run, which catches IOException only.
Invert the condition and keep the declared type.
