There is no way for a static library + to express link dependencies, so there will also be `rdkafka-static.pc` + pkg-config file generated that contains linker flags for the external + dependencies. + Those external dependencies are however most likely only available on the + build host, so this static library is not particularily useful for + repackaging purposes (such as for high-level clients using librdkafka). + + * a self-contained static-library (`librdkafka-static.a`) which attempts + to contain static versions of all external dependencies, effectively making + it possible to link just with `librdkafka-static.a` to get all + dependencies needed. + Since the state of static libraries in the various distro and OS packaging + systems is of varying quality and availability, it is usually not possible + for the librdkafka build system (mklove) to generate this completely + self-contained static library simply using dependencies available on the + build system, and the make phase of the build will emit warnings when it + can't bundle all external dependencies due to this. + To circumvent this problem it is possible for the build system (mklove) + to download and build static libraries of all needed external dependencies, + which in turn allows it to create a complete bundle of all dependencies. + This results in a `librdkafka-static.a` that has no external dependecies + other than the system libraries (libc, pthreads, rt, etc). + To achieve this you will need to pass + `--install-deps --source-deps-only --enable-static` to + librdkafka's `./configure`. + + * `rdkafka.pc` and `rdkafka-static.pc` pkg-config files that tells + applications and libraries that depend on librdkafka what external + dependencies are needed to successfully link with librdkafka. + This is mainly useful for the dynamic librdkafka librdkafka + (`librdkafka.so.1` or `librdkafka.1.dylib` on OSX). + + +**NOTE**: Due to libsasl2/cyrus-sasl's dynamically loaded plugins, it is +not possible for us to provide a self-contained static library with +GSSAPI/Kerberos support. + + + +### The artifact pipeline + +We rely solely on CI systems to build our artifacts; no artifacts must be built +on a non-CI system (e.g., someones work laptop, some random ec2 instance, etc). + +The reasons for this are: + + 1. Reproducible builds: we want a well-defined environment that doesn't change + (too much) without notice and that we can rebuild artifacts on at a later + time if required. + 2. Security; these CI systems provide at least some degree of security + guarantees, and they're managed by people who knows what they're doing + most of the time. This minimizes the risk for an artifact to be silently + compromised due to the developer's laptop being hacked. + 3. Logs; we have build logs for all artifacts, which contains checksums. + This way we can know how an artifact was built, what features were enabled + and what versions of dependencies were used, as well as know that an + artifact has not been tampered with after leaving the CI system. + + +By default the CI jobs are triggered by branch pushes and pull requests +and contain a set of jobs to validate that the changes that were pushed does +not break compilation or functionality (by running parts of the test suite). +These jobs do not produce any artifacts. + + +For the artifact pipeline there's tag builds, which are triggered by pushing a +tag to the git repository. +These tag builds will generate artifacts which are used by the same pipeline +to create NuGet and static library packages, which are then uploaded to +SemaphoreCI's project artifact store. + +Once a tag build pipeline is done, you can download the relevant packages +from the Semaphore CI project artifact store. + +The NuGet package, `librdkafka.redist.<version>.nupkg`, needs to be +manually uploaded to NuGet. + +The `librdkafka-static-bundle-<version>.tgz` static library bundle +needs to be manually imported into the confluent-kafka-go client using the +import script that resides in the Go client repository. + + +**Note**: You will need a NuGet API key to upload nuget packages. + + +See [nuget/nugetpackaging.py] and [nuget/staticpackaging.py] to see how +packages are assembled from build artifacts. + |
