Switch .NET tracer to injecting both base64 & binary headers #6448

veerbia · 2024-12-16T18:24:33Z

Summary of changes

Switch .NET tracer to injecting both base64 & binary headers
Binary headers can be disabled via a config variable: DD_DATA_STREAMS_LEGACY_HEADERS=false (defaults to true)
.NET tracer, when extracting the context from headers looks at both base64 & binary headers

Reason for change

Data Streams previously used binary encoding in Kafka headers. This was causing issues in cross language communication because of the difference in negative byte handling. That’s why we switched to base64 encoding.
Today, .NET is the only remaining tracer using binary encoding for Kafka, SQS & RabbitMQ.

This is causing 3 issues:

Communication between .NET & Java breaks, since Java doesn’t support negative bytes in Kafka headers
Manual instrumentation breaks between .NET and any other language, since manual instrumentation uses base64 encoding
.NET can’t consume payloads from any other tracers, since the other tracers encode in base64

Also, byte headers are causing a crash of the .NET application (not reproduced yet).

Implementation details

Injects base64-encoded headers by default to ensure cross-language compatibility.
Binary headers are injected only if DD_DATA_STREAMS_LEGACY_HEADERS (default: true) is enabled for backward compatibility.
Prefers base64 headers for extraction. If base64 is unavailable or malformed, it falls back to binary headers when legacy headers are enabled.
A new configuration setting DD_DATA_STREAMS_LEGACY_HEADERS controls whether binary headers are included.

Test coverage

I've added tests for the following cases:

Inject_WhenLegacyHeadersDisabled_DoesNotIncludeBinaryHeader
- Ensures that when legacy headers are disabled, the binary header is not included in the injected headers.
Extract_WhenBothHeadersPresent_PrefersBase64Header
- Confirms that when both Base64 and binary headers are present, the Base64 header is preferred for extraction.
InjectedHeaders_HaveCorrectFormat
- Validates that injected headers are in the correct format, especially checking if the Base64-encoded header is valid and correctly decoded.
InjectHeaders_WhenLegacyHeadersDisabled_DoesNotIncludeLegacyHeader
- Ensures that legacy headers are excluded when legacy header support is disabled.
Inject_WhenLegacyHeadersEnabled_IncludesBothHeaders
- Confirms that both Base64 and binary headers are injected when legacy header support is enabled.
Extract_WhenBase64HeaderIsMalformed_ReturnsFallbackToBinary
- Verifies that if the Base64 header is malformed, the system falls back to using the binary header for extraction.

Other details

This appears to be handled already and doing it here just dupes the content. And it didn't add comma's between the JSON fields which ccause JSON deserialization errors. Additionally, it was re-encoding the Base64 again.

so that it isn't disabled.

This is added already below, but initially it wasn't obivous because the legacy data streams was always false.

Execution-Time Benchmarks Report ⏱️

Execution-time results for samples comparing the following branches/commits:

Execution-time benchmarks measure the whole time it takes to execute a program. And are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are shown in red. The following thresholds were used for comparing the execution times:

Welch test with statistical test for significance of 5%
Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).

Remove DSM JSON injection

be18958

This appears to be handled already and doing it here just dupes the content. And it didn't add comma's between the JSON fields which ccause JSON deserialization errors. Additionally, it was re-encoding the Base64 again.

so that it isn't disabled.

Remove duplicate PropagationKey header

This is added already below, but initially it wasn't obivous because the legacy data streams was always false.
