| # PURPOSE: | |
| # | |
| # We want to provide LLVM snapshot packagers and distributors with *daily* | |
| # source tarballs that are easy to consume. Typically, packagers have to clone | |
| # the whole LLVM monorepo themselves and run the "git archive" command to | |
| # generate source tarballs for each LLVM component. Those tarballs are the | |
| # input to the packaging system (e.g. DEB, RPM, etc.). With this workflow we | |
| # can provide the daily source tarballs to the community similar to the source | |
| # tarballs of regular releases. Everything a packager needs to know is the | |
| # current date (YYYYMMDD) and go ahead and download the LLVM component of | |
| # choice, i.e.: | |
| # | |
| # https://github.com/fedora-llvm-team/llvm-snapshots/releases/download/source-snapshot/clang-tools-extra-20210417.src.tar.xz | |
| # | |
| # Notice the absence of the LLVM version. To get it, a packager can download | |
| # | |
| # https://github.com/fedora-llvm-team/llvm-snapshots/releases/download/source-snapshot/llvm-release-20210417.txt | |
| # | |
| # To get the git revision standalone: | |
| # | |
| # https://github.com/fedora-llvm-team/llvm-snapshots/releases/download/source-snapshot/llvm-git-revision-20210417.txt | |
| # | |
| # The subtle benefit of this naming convention is that you don't need to know | |
| # the LLVM version before downloading the source tarball. I mean, how could | |
| # you know the LLVM version of a daily snapshot upfront? In fact, the source | |
| # tarball for "clang-tools-extra" contains no version information whatsoever | |
| # and yet it requires a special LLVM version which is why we provide the | |
| # "llvm-release-<YYYYMMDD>.txt" files. | |
| # | |
| # WHAT: | |
| # | |
| # At 00:00 in the morning, this workflow creates source tarballs for the | |
| # latest stable commit of all LLVM components of the current "main" branch and | |
| # uploads them as assets to a pre-release called "source-snapshot". (A | |
| # pre-release won't show up on the github repositories front-page.) The assets | |
| # that are seven days or older will be deleted on each run. If the workflow | |
| # runs twice a day, the old assets of the day will also be deleted. If the | |
| # "source-snapshot" release doesn't exist, it will be created automatically. | |
