Profiling disabled due to missing extension on Heroku and Elastic Beanstalk (ddtrace 1.1.0) #2067
Comments
Hey @theocodes thanks for the report and interest in the Profiler! This is definitely not expected, as indeed x86_64 Linux is fully supported. Ever since the PR you mentioned (#2028) the profiler gets compiled and linked to the libddprof library, which is shipped in the The weird part is that the error you shared seems to indicate that the profiler did get successfully compiled and linked during installation (otherwise the error message would be different), so whatever went wrong, it went wrong after In particular, it looks like the
|
Hi @ivoanjo Thanks for looking into this! I'm not sure what went wrong there but I'm unable to reproduce it now - everything seems to be working.. 🤔 Maybe let's close this issue for now and I'll let you folks know if it happens again? |
Great! Feel free to reach out if there's anything we can do to help, and happy profiling :) |
Hey @ivoanjo, I've hit this error myself today. I get the following output from the command you suggested to run:
Currently running Ruby 3.1.2 |
I've tested reverting ddtrace back to 1.0.0 and this gets rid of the errors. I mentioned that we're running Ruby 3.1.2 but we're also running Rails 7.0.3 |
Thanks @Baron-burton for the extra info. Yes, this issue was the result of a new change in 1.1, but obviously not intended to break ;) The output you shared is quite interesting/helpful, since it does confirm that whatever paths were observed during installation to reach So I can investigate further, could you provide the output of the following:
And a couple of questions:
Thanks again, and I'll get to the bottom of this issue soon :) |
Hey @ivoanjo, thanks for getting back to me 1️⃣ ldd
2️⃣ gem contents libddprof
3️⃣ strings
4️⃣ Ruby installation We rely on Heroku to install our Ruby version. This is done by simply specifying the version in our Gemfile, Heroku picks it up from there and installs the required version. |
This is great! Clearly the gems are in a different folder during installation:
But afterwards things shift around. I think I have enough to work on a fix and report back, please hang tight :) |
Thanks so much @ivoanjo 💪 |
Just a quick update that I was able to reproduce this issue. It happens due to the way Heroku builds gems during deployment and then moves them to a different folder afterwards. For now I recommend going back to |
Do we have any timeline when 1.2.0 will be released ? Btw : This issue happens in AWS Elastic Beanstalks too. |
Thanks for the patience! We expect to have it out within the next two weeks. Fixing this and getting 1.2.0 released is at the top of the priority list.
Interesting, I did not know that! I've been able to reproduce the issue on Heroku, and I'll additionally validate that the fix also works on Elastic Beanstalk. |
…anstalk As reported in #2067, in these environments ddtrace (and libddprof) are moved after installation, which broke linking from the profiling native extension to libddprof. As a fix/"workaround", we additionally add the relative path between both gems while linking; see the comments on the `.libddprof_folder_relative_to_native_lib_folder` helper for more details and how this works. Note that key word above is **aditionally** -- e.g., we're adding more paths in which to find libddprof, and keeping the existing absolute path, so this should not impact any setups where things were already working fine. Big and special thanks to @sanchda for brainstorming with me on this issue. Fixes #2067
Thanks folks for the patience so far! I've merged in a fix for this, and the plan is to release it as part of ddtrace 1.2.0 next week. |
👋 @Baron-burton @seuros the fix for this issue has been released in v1.2.0. |
@ivoanjo : now with the update i get same settings worked in 1.0.0 |
…ension dir **What does this PR do?** This PR is a follow-up to #3582 . In that PR, we fixed loading the profiling native extension so that it could be loaded from the Ruby extensions directory (see the original PR for more details). It turns out this was not enough! Specifically, the customer reported that they saw the following error > Profiling was requested but is not supported, profiling disabled: There was an error loading the profiling > native extension due to 'RuntimeError Failure to load datadog_profiling_native_extension.3.2.2_x86_64-linux > due to libdatadog_profiling.so: cannot open shared object file: No such file or directory Specifically, what this message tells is that we're finding the profiling native extension BUT it's failing to load BECAUSE the dynamic loader is not able to find its `libdatadog_profiling.so` dependency. From debugging the issue with the customer, I suspect that what we're seeing here is a repeat of #2067 / #2125 , that is, the paths where the profiler is compiled are changed at deployment, and so we also need to adjust the relative rpath to account for this. I haven't yet confirmed with the customer that this is their issue, BUT I was able to reproduce the exact problem if I moved the installation of the library in the way I mention above (see "how to test the change", below). **Motivation:** Fix this weird corner case that made the profiler not load. **Additional Notes:** This is a really really weird corner case, so I'm happy to further describe what the issue is if my description above + the comments in the code are still too cryptic to understand. **How to test the change?** I've added test code for the helper, but actually validating the whole rpath thing is a bit annoying. Here's how I triggered the issue myself, and then used it to validate the fix: ``` # Build fixed gem into folder, will be used later $ bundle exec rake build datadog 2.0.0.rc1 built to pkg/datadog-2.0.0.rc1.gem. # Open a clean Ruby docker installation $ docker run --network=host -ti -v `pwd`:/working ruby:3.2.2-bookworm /bin/bash # I've created a minimal test gemfile ahead of time /working/rpathtest# cat gems.rb source 'https://rubygems.org' gem 'datadog' # Tell bundler to install the gem into a folder /working/rpathtest# bundle config set --local path 'vendor/bundle' /working/rpathtest# bundle install # Confirm profiler works: /working/rpathtest# DD_PROFILING_ENABLED=true bundle exec ddprofrb exec ruby -e "sleep 1" # ...

Hi 👋
Came across the following while attempting to set up profilingf or a rack app
After some digging I can see this (at least the error message) may be caused by the 1.1.0 release which added
libddprof
as a dependency. However, it's not clear to me whether this is intended or a bug..The PR Seems to suggest x86_64 linux is supported and that is exactly what I am using and yet I get the error.
Would youf folks be able to shed some light on it?
Thanks!
