# Standardise GitHub downloads and updates
|
|
# Download API has three forms:
|
|
# Archive:
|
|
# url = <owner>/<repo>/archive/<ref>.tar.gz
|
|
# dir = <repo>-<ref>
|
|
# if <ref> starts with a single `v`, it is removed from dir
|
|
#
|
|
# Release:
|
|
# Manually uploaded distribution tarballs, especially useful for
|
|
# autotools packages with generated sources. No universal convention,
|
|
# but the default is:
|
|
# url = <owner>/<repo>/releases/downloads/<ref>/<repo>-<version>.[archive extension] | tar.gz
|
|
# dir = <repo>-<version>
|
|
#
|
|
#
|
|
# Tarball:
|
|
# url = <owner>/<repo>/tarball/<ref>/output-file.tar.gz
|
|
# dir = <owner>-<repo>-<short sha>
|
|
|
|
# Filename doesn't matter as we stream the url to a name of our choosing.
|
|
#
|
|
# The archive API could be used for all packages, however, if the reference
|
|
# is any sort of SHA, the full SHA is used for the directory. We could `cd`
|
|
# into it without knowing the SHA beforehand, but the directory length would
|
|
# be comical in logs etc.
|
|
#
|
|
# The release API is based on tags but the uploaded tarballs may use
|
|
# any naming convention for the filename and subdir, and also other
|
|
# archive types e.g. *.xz
|
|
#
|
|
# The tarball API accepts references to commits or tags, always using the
|
|
# short SHA as the directory. In this case, tag tracking packages would have
|
|
# to store the SHA (see #1002). However, this only works for lightweight
|
|
# tags, not annotated tags that most projects use for releases.
|
|
#
|
|
# In summary, we have to use all three.
|
|
|
|
|
|
# The tarball API determines the short SHA length used in the directory name.
|
|
# Chances of a collision on a "given" commit seem to decrease as the chance
|
|
# of "any" collision increases. If that changes in the future, `make update`
|
|
# will fix it.
|
|
# Currently (2015-12) the API sets the short SHA length to:
|
|
GITHUB_SHA_LENGTH := 7
|
|
|
|
# Packages must set the following metadata:
|
|
# Track branch - Tarball API
|
|
# GH_CONF := owner/repo/branches/branch
|
|
# updates will use the last commit from the specified branch as
|
|
# a version string and bypass `sort -V`
|
|
#
|
|
# Track releases - Release API
|
|
# GH_CONF := owner/repo/releases[/latest], tag prefix, tag suffix, tag filter-out, version separator, archive extension
|
|
# updates can optionally use the latest non-prerelease with /latest
|
|
# or manually specify version numbering based on:
|
|
# <tag prefix><s/<version sep>/./version><tag suffix>
|
|
#
|
|
# Track tags - Archive API
|
|
# GH_CONF := owner/repo/tags, tag prefix, tag suffix, tag filter-out, version separator
|
|
# updates will construct a version number based on:
|
|
# <tag prefix><s/<version sep>/./version><tag suffix>
|
|
#
|
|
GH_APIS := branches releases tags
|
|
|
|
# common tag filtering is applied with `grep -v`:
|
|
GITHUB_TAG_FILTER := alpha\|beta\|rc
|
|
|
|
# More complex filters can fall back to `MXE_GET_GH_TAGS` which returns
|
|
# a list for post-processing.
|
|
|
|
# ...and finally, auto-configure packages based on above metadata:
|
|
# - `eval` these snippets during PKG_RULE loop (where PKG is in scope).
|
|
# - `call` or `eval` from package makefiles requires complex quoting
|
|
# and looks out of place.
|
|
# - don't redefine manually set standard variables (FILE, SUBDIR, URL, UPDATE)
