Prejit support on FunctionsNetHost #2711
base: main
Are you sure you want to change the base?

@steveisok @ivdiazsa FYI. |
@khkh-ms FYI. I used a previously generated trace for this PR. Once your changes are done, we could replace this file with that. Let's merge both traces to single file (like what we do for host) |
@steveisok @ivdiazsa Appreciate if you could do review the changes. |

Can you added unit tests where possible?
I don't have further comments other than addressing the ones that have been pointed out so far. |
We don't have any tests as of today as what we want to validate is the native output. There has been discussion about adding an E2E test which simulates the linux scenarios as part of build pipeline (potentially a nightly build). Never got a chance to create a work item until now. #2724 I think that should be the priority. We can certainly revisit as we have more cycles to work on this. |
Looks good to me! Glad you were able to work this in 👍 |

@eliaslopezgt please replace coldstart.jittrace

Can we instead make an interop call from the native host following the pattern used against the worker?

Set all appropriate assembly properties here.

These are not part of our safe list of dependencies to bring in. At least in this iteration, we don't want to have this present.

Are we supposed to use DownloadPipelineArtifact
? 1ES has its own syntax for artifact inputs:

Instead of a separate solution file, can we not use an existing one?

Fixes #2637
This PR adds support for pre-jitting framework methods during placeholder mode. Currently this is enabled only for net8 onwards. This behavior can be explicitly disabled by setting
AZURE_FUNCTIONS_FUNCTIONSNETHOST_DISABLE_PREJIT
environment variable value to0
.See internal wiki page for more context.
I will have a separate follow up PR for fixing the build pipeline & nuget packaging needed for this change.Also included the build pipeline changes to include the new artifacts in the final package.Did a minor version bump.
