0.78.0

Symfony integration partially broken

Some Symfony spans may be of service unnamed-php-service instead of the proper service name. Under version 0.77.0 the behaviour is as expected.

Added

• Instrument pcntl_fork and reset tracing when it is called #1633 (Thanks @jlesueur)
• ARM64 support (Build arm images in CI) #1701

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 single span ingestion mechanism #1628
• Add "recurse" => true option to hook/trace config array #1677

Changed

Fixed

• Check for datadog-profiling in startup only instead of inside a message_handler #1670. This fixes a possible crash when all of tracer, profiler and appsec are loaded.
• 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.
• Fix -Werror=address-of-packed-member #1664

Internal changes

• Skip curl test if curl is not loaded #1668

Profiling (v0.7.2)

0.76.1

apache reload will cause crashes

Please upgrade to 0.76.2, if you get crashes with apache with versions 0.76.0 or 0.76.1.

Fixed

• Bump PHP minimum version in PECL #1652
• PHP 7.3+ Fix compatibility with opcache #1656

Internal changes

• %d resource ids in language tests #1657

0.76.0

Instrumentation partly broken with opcache

Note: If you are using opcache with PHP 7.3 or newer, it is advised to skip this version in favor of 0.76.1.

As part of a major refactor of our instrumenting code, we made ourselves incompatible with JIT (it will report an error that JIT will be disabled, but still work).
Additionally, with opcache active, a lot of user functions are not traceable anymore on PHP 7.3 and newer. This means that the resulting traces will be missing a lot of information.
