Profiling (0.11.0)

Profiling is now installed and enabled when --enable-profiling is passed on the installer. Previously it was installed but not enabled. This removes one step in onboarding as the environment variable DD_PROFILING_ENABLED no longer needs to be set to 1, which can be difficult in some situations. The recommended way to configure profiling is to use .ini settings, which is generally easier.

Added

• Add .ini support #1775.
• Groundwork for allocation profiling #1794

Changed

• Bump libdatadog to 0.9 #1782.
• Bump env_logger to 0.9.3 #1804.

Internal Changes

• Add troubleshooting to README #1761

0.81.1

Fixed

• Fix span limiter not being reset in long running processes #1785

0.81.0

Traces disappearing

We have an issue causing span counters to not be reset properly after a flush. Thus the span limit of 1000 being reached, and then hooks not being executed anymore. This impacts long-running CLI processes only.

Added

0.77.0

⚠️ The tracer and profiling packages for PHP 7 and 8 are built on CentOS 7. These packages will not run on older GNU Linux versions like CentOS 6, Debian 7, and Ubuntu 12.04.

Added

• Add opcode shutdown handlers, fix integrations after repeated minit #1669. This fixes a crash when using reload on apache (sending SIGUSR1).
• (PHP 7) Fix curl wrapper use after free #1662. This fixes a possible crash when curl handles are manually released within destructors inside the PHP shutdown sequence.
