    [BUG] Constant HTTP 500 with preloading enabled on version 0.48.3

    Bug description

    We're seeing obscure but constant HTTP 500 with PHP preloading enabled and Datadog extension loaded. Once the extension is removed (rm /etc/php/7.4/fpm/conf.d/98-ddtrace.ini /etc/php/7.4/fpm/conf.d/99-ddtrace-custom.ini) everything works fine.

    [Feature] Enable distributed tracing with dd_trace_method and dd_trace_function

    Is your feature request related to a problem? Please describe. In order to enable distributed tracing for example for grpc requests, in dd_trace_method or dd_trace_function, we need to be able to set and extract the trace id and parent id which are sent and received via headers.

    Describe the solution you'd like In dd_trace_method something like this should be possible:

    When receiving a request:

    $span->trace_id = $tracingHeaders[Propagator::DEFAULT_TRACE_ID_HEADER];
$span->parent_id = $tracingHeaders[Propagator::DEFAULT_PARENT_ID_HEADER];

    When sending a request:

    $tracingHeaders[Propagator::DEFAULT_TRACE_ID_HEADER] = $span->trace_id;
$tracingHeaders[Propagator::DEFAULT_PARENT_ID_HEADER] = $span->parent_id;

    Describe alternatives you've considered In general, I think it would be helpful, if the created internal span from dd_trace_method is configurable like in dd_trace

  • [BUG] Potential incompatibility with ionCube Extension

    [BUG] Potential incompatibility with ionCube Extension

    Bug description

    We are using the Unirgy Rapidflow module within a Magento 2 instance. This module is partially ionCube encoded. We've found that if the ddtrace extension is enabled, this module can cause segmentation faults in PHP when performing some operations. Disabling the ddtrace extension or setting ddtrace.enable to Off in PHP INI resolves the issues with the Rapidflow module.

    The initiation of this modules functionality is done through a web request which is handled by Apache and passed via mod_proxy_fcgi to PHP-FPM. Testing was done using a Docker container running locally on my development machine. We run similar setups in our production environment which is experiencing the exact same issue.

    More than willing to do debugging on my end given a bit of direction on what would be the most helpful. Given this is a local environment with a custom container image, I can install whatever tools necessary without any constraints.

    Note that we were aware of existing incompatibility with ionCube prior to version 0.71.0. We used the SourceGuardian extension with a SourceGuardian encoded version of this module to work around that problem. This worked until a recent update to the module where we started seeing segmentation faults. At that time, we updated to ddtrace 0.71.0 and the ionCube encoded version of the module along with the latest ionCube loader 11.0.1. This seemed to be fully working, but we started to find these segmentation faults while running some profiles even though other similar profiles are working without issue.

    Also note that because this is a local instance, I do not have the agent setup. This does not impact the ability to reproduce this issue so I did not take the time to get that setup.

  • [BUG] Increased memory usage/leak after upgrading from 0.64.1 to 0.67.0+

    [BUG] Increased memory usage/leak after upgrading from 0.64.1 to 0.67.0+

    Bug description

    We are seeing memory usage typical for memory leaks on one of our apps with PHP 8.1 running and DDTrace versions 0.67.0, 0.68.2, 0.69.0 (we were not able to test 0.70+ due to reported issue https://github.com/DataDog/dd-trace-php/issues/1544) after upgrading from DDTrace 0.64.1 on long-running processes (mainly queue consumers).

    In order to investigate further what is happening, we updated a second application (running PHP 8.0) also from DDTrace 0.64.1 to 0.69.0 and we can see non-negligible memory usage increase although I cannot say for sure it's a memory leak or just an increase in memory footprint since we're scaling the application a lot and therefore lifetime of a container is in matter of minutes, not hours.

    I've seen that DDTrace started to use WeakRef/WeakMap on PHP 8.0+. I'm not sure if it's somehow related but we encountered issues with WeakRef that is reported and verified here: https://bugs.php.net/bug.php?id=81027.

    We're also heavily using Guzzle in many of the consumers that now fail on memory.

    I'd love to provide more information but I'm not sure how to debug ddtrace memory usage properly, especially when it exhibits only in long-running processes (I may try Blackfire but it's not easy to replicate the "traffic" locally).

    I'm also not entirely sure it's DDTrace fault but as I said nothing had been changed on the second application except for DDTrace version and increased memory usage is clearly visible.

    I'd appreciate any insight into what MIGHT have changed, any debugging tips and if an increased memory usage is expected or not.

    Thank you!

    Screenshot 2022-03-18 at 11 46 43 (1) (First application, showing average memory usage) Screenshot 2022-03-21 at 16 05 33 (Second application, nothing had been changed here except for DDTrace version, showing average memory usage, aggregated from multiple containers)

    [BUG] SIGSEGV after upgrading to v0.49.0 from v0.44.1

    Bug description

    I've started seeing this issue after the upgrade to 0.49.0. It occurs rarely and only in production.

    I'd be happy to provide core dump but, there's something wrong with my php-fpm config (probably), because it doesn't generate core dump when this issue occurs. BTW, if you know reliable steps to get php to segfault, please let me know :)

    At this point I'm looking for some guidance on what I can check to narrow down the potential causes.

    Thanks!

    [Feature] php-amqplib Integration

    As a developer, I'd like to see information about RabbitMQ messages inside traces.

    Solution Support for the php-amqplib library, which is as far as I could research the most widely used RabbitMQ client for PHP.

    Alternatives I've considered Implementing custom instrumentation myself. I would prefer to have this out of the box though.

    Interesting methods Methods I personally am interested in:

    AMQPChannel

    • PhpAmqpLib\Channel\AMQPChannel::basic_publish()
    • PhpAmqpLib\Channel\AMQPChannel::basic_consume()
    • PhpAmqpLib\Channel\AMQPChannel::basic_get()
    • PhpAmqpLib\Channel\AMQPChannel::basic_ack()
    • PhpAmqpLib\Channel\AMQPChannel::basic_nack()
    • PhpAmqpLib\Channel\AMQPChannel::basic_cancel()

    Especially interesting parameters: Exchange, Queue, Routing Key

    AbstractConnection

    • PhpAmqpLib\Connection\AbstractConnection::connect()
    • PhpAmqpLib\Connection\AbstractConnection::reconnect()

    It might make sense to extend this list.

  • [Tracer] Show error message when PDO returns an error

    [Tracer] Show error message when PDO returns an error

    Description

    Adds the error message in the error message tag when available. This gives more information on where the issue is. Error messages are contained inside the errorInfo array. The specs state it contains 3 elements but SQLServer seems to set more than that.

    This extra data shouldn't contain sensitive data as it should be close to what we get on PDOException when there is one.

  • Remove libexecinfo on Alpine

    Remove libexecinfo on Alpine

    Description

    Fix GH-1824. The quick summary is Alpine 3.17 removed this library, and on older versions it's apparently not great quality anyway.

    The biggest negative impact of this change is that when DD_TRACE_HEALTH_METRICS_ENABLED or DD_LOG_BACKTRACE or their INI equivalents are used, and a SIGSEGV occurs, that a backtrace will no longer be displayed. In other words, although this is a breaking change for Alpine platforms, the impact is quite small.

    On the other hand, it has one less runtime dependency; Alpine users will no longer need to apk add libexecinfo before installing the tracer.

    feat(tracing): add component tag

    Description

    This PR introduces the component tag within the tracer for all supported integrations. The component tag is set to the name of the integration that produced the span and should be set on all integration-produced spans. Motivation for this change is to make Datadog APM tracer libraries tagging and span formatting more consistent.

  • Ini file created by datadog-setup.phpdoes not align with rpm package

    Ini file created by datadog-setup.phpdoes not align with rpm package

    Hey guys,

    we encountered several "PHP Warning: Module 'ddtrace' already loaded in Unknown on line 0" warnings after we used your installer over the last couple of weeks. We had DD as well as the profiler installed before we used your installer for the first time.

    The reason was a bit tough to find but logical at the end :-)

    https://github.com/DataDog/dd-trace-php/blob/7cdb199db6513d10eaaceb1ca3c5ae33465dae8c/datadog-setup.php#L227

    We install all DD packages using the remi repo rpm packages on Centos ( let's take a jump back to the past: https://github.com/DataDog/dd-trace-php/issues/214 ). Remi adds the ini files with the prefix 40-ddtrace.ini. Thus all updates to the rpm packages leads to a duplicate ini file being present. Your installer creates 98-ddtrace.ini.

    We now simply moved your ini file to 40-ddtrace.ini. But still running the installer again or setting up a fresh system will always lead to this ini clash.

    Maybe you could add a check to your installer to see if a xx-ddtrace.ini file is already present in /php.d/ and offer to overwrite these instead of creating a new file?

    Best regards,

    Jan

  • Use numbers instead of numeric strings in pprof labels (update libdatadog)

    Use numbers instead of numeric strings in pprof labels (update libdatadog)

    Description

    Use numbers instead of numeric strings in pprof labels. This is more efficient, and may open the doors to having a global string table in the future, which could be used to create a global symbol table as well.

    This pairs with Datadog/libdatadog#80. This is blocked from merging at the moment because:

    1. There's an issue with Code Hotspots.
    2. A specific git revision is hardcoded until the libdatadog PR merges.
