0.21.0

Upgrading to 0.21.0

With this release we are moving distributed tracing settings to be enabled by default. This change means that you no longer need to explicitly enable distributed tracing for any integration.

Changes

Improvements

• Enable distributed tracing by default (#818)
  • aiohttp
  • bottle
  • flask
  • molten
  • pylons
  • pyramid
  • requests
  • tornado
• [testing] Ensure consistent use of override_config and override_env (#815)
• [core] Break up ddtrace.settings into sub-modules (#814)
• [tests] Simplify elasticsearch CI test commands (#813)
• [core] Remove sending of service info (#811)
• [core] Add import hook module (#769)

0.20.4

Upgrading to 0.20.4

This is a bug fix release, no code changes are required.

In this release we have fixed a bug that caused some configuration values to not get updated when set.

Changes

Bug fixes

• [bug] Integration config keys not being updated (#816)

0.20.3

Upgrading to 0.20.3

This is a bug fix release that requires no changes.

This release includes a fix for context propagation with futures. Under the right conditions we could incorrectly share a trace context between multiple futures threads which result in multiple traces being joined together in one.

Changes

Bug fixes

• [core] Allow futures to skip creating new context if one doesn't exist (#806)

0.20.2

Upgrading to 0.20.2

No changes are needed to upgrade to 0.20.2.

This big fix release includes changes to ensure we properly read the HTTP response body from the trace agent before we close the HTTP connection.

Changes

Bug fixes

• [core] Call HTTPResponse.read() before HTTPConnection.close() (#800)

Improvements

• [tests] limit grpcio version to >=1.8.0,<1.18.0 (#802)
• [tools] Add confirmation to 'rake pypi:release' task (#791 )

0.20.1

Upgrading to 0.20.1

No changes are needed to upgrade

Changes

Bug fixes

[celery] Ensure celery.run span is closed when task is retried (#787)

Read the full changeset and the release milestone.

0.20.0

Upgrading to 0.20.0

We have added support for logs injection to the tracer. If you are already using ddtrace-run, the integration can be enabled with setting the environment variable DD_LOGS_INJECTION=true. The default behavior once logs injection is enabled is to have trace information inserted into all log entries. If you prefer more customization, you can manually instrument and configure a log formatter with the tracer information.

Changes

New Integrations

• [mako] Add Mako integration (#779 -- thanks @wklken)

Enhancements

• [core] Tracer and logs integration (#777)

0.19.0

Upgrading to 0.19.0

With 0.19.0 we have decided to disable the tracing of dbapi2 fetchone()/fetchmany()/fetchall() methods by default.

This change effects all integrations which rely on the dbapi2 API, including psycopg2, mysql, mysqldb, pymysql, and sqlite3.

We have introduced this change to reduce the noise added to traces from having these methods (mostly fetchone()) traced by default.

With fetchone() enabled the traces received can get very large for large result sets, the resulting traces either become difficult to read or become too large causing issues when flushing to the trace agent, potentially causing traces to be dropped.

To re-enable the tracing of these methods you can either configure via the environment variable DD_DBAPI2_TRACE_FETCH_METHODS=true or manually via:

from ddtrace import config
config.dbapi2.trace_fetch_methods = True

Changes

Bugs

[dbapi2] disable fetchone/fetchmany/fetchall tracing by default (#780)
[opentracing] Fixing context provider imports for scope manager (#771 -- thanks @Maximilien-R)

Enhancements

[tests] test python setup.py sdist and twine check on build (#782)
[core] Add API to configure Trace Search (#781)
[core] Enable priority sampling by default (#774)
