DataDog/dd-trace-py v2.0.0 on GitHub

Prelude

The Datadog APM Python team is happy to announce the release of v2.0.0 of ddtrace. This release drops support for Python 2.7, 3.5, and 3.6. This release adds support for Python 3.12.

Important
If you are on version of Python not supported by v2, we will continue to maintain the ddtrace v1 with bug fixes.

Note
Before upgrading to v2.0.0, we recommend users install ddtrace~=1.18.0 and enable deprecation warnings. All removals to the library interface and environment variables in v2 were deprecated in the 1.x release line.

Note
The changes to environment variables apply only to the configuration of the ddtrace library and not the Datadog Agent.

Upgrading summary

Functionality changes

The default logging configuration functionality of ddtrace has been changed to avoid conflicting with application logging configurations. DD_CALL_BASIC_CONFIG has been removed and the ddtrace logger will log to stdout by default, or a log file as specified using DD_TRACE_LOG_FILE.

Setting the environment variable DD_TRACE_PROPAGATION_STYLE='b3' to enable B3 propagation has been removed. Please use DD_TRACE_PROPAGATION_STYLE='b3multi' instead.

Removed deprecated environment variables

These environment variables have been removed. In all cases the same functionality is provided by other environment variables and replacements are provided as recommended actions for upgrading.

Variable	Replacement
`DD_GEVENT_PATCH_ALL`	None
`DD_AWS_TAG_ALL_PARAMS`	None
`DD_REMOTECONFIG_POLL_SECONDS`	`DD_REMOTE_CONFIG_POLL_INTERVAL_SECONDS`
`DD_CALL_BASIC_CONFIG`	None
`DD_TRACE_OBFUSCATION_QUERY_STRING_PATERN`	`DD_TRACE_OBFUSCATION_QUERY_STRING_REGEXP`

Removed deprecated library interfaces

These methods and module attributes have been removed. Where the same functionality is provided by a different public method or module attribute, a recommended action is provided for upgrading. In a few limited cases, because the interface was no longer used or had been moved to the internal interface, it was removed and so no action is provided for upgrading.

	`APPSEC_JSON`
	`APPSEC_EVENT_RULE_VERSION`

Upgrade Notes

DD_GEVENT_PATCH_ALL is removed. There is no special configuration necessary to make ddtrace work with gevent if using ddtrace-run.
DD_AWS_TAG_ALL_PARAMS is removed. The boto/botocore/aiobotocore integrations no longer collect all API parameters by default.
DD_REMOTECONFIG_POLL_SECONDS is removed. Use the environment variable DD_REMOTE_CONFIG_POLL_INTERVAL_SECONDS instead.
APPSEC_ENABLED, APPSEC_JSON, APPSEC_EVENT_RULE_VERSION, APPSEC_EVENT_RULE_ERRORS, APPSEC_EVENT_RULE_LOADED, APPSEC_EVENT_RULE_ERROR_COUNT, APPSEC_WAF_DURATION, APPSEC_WAF_DURATION_EXT, APPSEC_WAF_TIMEOUTS, APPSEC_WAF_VERSION, APPSEC_ORIGIN_VALUE, APPSEC_BLOCKED, IAST_JSON, IAST_ENABLED, IAST_CONTEXT_KEY are removed. This should not affect existing code as these deprecated ASM constants were meant for private use only.
ddtrace.contrib.starlette.get_resource, ddtrace.contrib.starlette.span_modifier, and ddtrace.contrib.fastapi.span_modifier are removed. The starlette and fastapi integrations now provide the full route and not just the mounted route for sub-applications.
ddtrace.contrib.starlette.config['aggregate_resources'] and ddtrace.contrib.fastapi.config['aggregate_resources'] are removed. The starlette and fastapi integrations no longer have the option to aggregate_resources, as it now occurs by default.
ddtrace.contrib.grpc.constants.GRPC_PORT_KEY is removed. Use ddtrace.ext.net.TARGET_PORT instead.
ddtrace.ext.cassandra.ROW_COUNT is removed. Use ddtrace.ext.db.ROWCOUNT instead.
ddtrace.ext.mongo.ROW_COUNT is removed. Use ddtrace.ext.db.ROWCOUNT instead.
ddtrace.ext.sql.ROW_COUNT is removed. Use ddtrace.ext.db.ROWCOUNT instead.
ddtrace.filters.TraceCiVisibilityFilter is removed.
ddtrace.tracer.DD_LOG_FORMAT is removed. As an alternative, please follow the log injection formatting as provided in the log injection docs.
DD_CALL_BASIC_CONFIG is removed. There is no special configuration necessary to replace DD_CALL_BASIC_CONFIG. The ddtrace logger will log to stdout by default or additionally to a file specified by DD_TRACE_LOG_FILE.
DD_TRACE_OBFUSCATION_QUERY_STRING_PATTERN is removed. Use DD_TRACE_OBFUSCATION_QUERY_STRING_REGEXP instead.

New Features

Adds support for Python 3.12.
Vulnerability Management for Code-level (IAST): Weak randomness vulnerability detection.

Bug Fixes

tracing: Encoding traces in the v05 format has a known issue for applications generating spans at a high frequency, causing approximately 1/10000000 spans to be misencoded. This change sets DD_TRACE_API_VERSION to v04 by default.
