[question] Shouldn't export-pkg provide package revision (prev) in json output?

[tonichedgehog]

What is your question?

Hi, I'm using the export-pkg command to create a Conan package of pre-built binaries, with the -f json format flag to capture information on the created package for further processing. But the exported package seems to have null for package revision (prev) in the json output. Am I missing something here, or is it perhaps intentional?

There is nothing wrong with the exported package, and when uploading it to a remote, the prev seems to be computed as expected. But it would be useful to obtain prev from the json output of export-pkg.

Conan version: 2.0.13
Os: Windows
Python: 3.11.2

Steps to reproduce with zlib from conan-center:

conan source --version 1.3 .
cd src
conan install ..

Then build zlib as an ordinary CMake project (might need to drop the CMAKE_INSTALL_PREFIX from the leading set() commands in zlib's CMakeLists.txt for the build to work), and create a Conan package of the results:

cmake --preset conan-default
cmake --build --preset conan-release
conan export-pkg --name zlib --version 1.3 -f json ..
