* Under the base URL there are supposed to be the repository files and a
subdirectory "packages".
* Fix the repository URL related confusion introduced earlier. The URL
in
the repository info (and thus in the repository file) is supposed to
be the base URL for the repository. It is not a (potentially)
different base URL for the package files. Package and repository
files were supposed to live in the same directory. Now, by requiring
the package files to live in a subdirectory -- which can also be a
symlink -- we gain some flexibility.
The URL in the repository config is usually the same as the in the
repository info, unless it refers to a mirror site. This allows for
mirrors to copy the original repository verbatim.
* Remove the PackageURL rule and introduce a DownloadPackage rule
instead. The URL for a package file cannot be computed in the jam
parsing phase anymore, as it contains the hash value of the package
list.
* BRepositoryConfig: Add PackagesURL() for convenience.
The package kit actually requires the files "repo", "repo.info",
"repo.sha256" to be located under the repository base URL, so the
approach to name the repository file "repo-<hash>" doesn't work.
Now there's a directory "<hash>" which contains the files.
This commit moves the computation of the hash and downloading the
repository file from the build_haiku_image script to the jam build
system. The repo.info is also downloaded and a repository config file
is generated.
gcc 2 doesn't support the weakref attribute. Rather use the regular
(target) method to initialize sCreateSolver instead (pthread once,
dlopen()). Since we know that we're on Haiku, that doesn't add any
dependencies that aren't available anyway.
* Build libsolv and the dependency solver part of the package kit for
the build platform.
* Add build tool get_package_dependencies. Given a list of package files
and a list of repository files it determines the additional packages
that need to be retrieved from the repositories and prints their URLs.
* Add rules to work with external repositories in the build system
(build/jam/RepositoryRules):
- PackageRepository declares an external repository with all its
packages. The URL of the repository file isn't specified. It is
computed from a given base URL and the SHA256 hash of the list of
package files.
- GeneratedRepositoryPackageList generates a file containing the file
names of all packages in a repository.
- IsPackageAvailable returns whether a package is available in any
repository.
- PackageURL returns the URL for a package.
* Declare the HaikuPorts repository for x86_gcc2
(build/jam/repositories/HaikuPorts/x86_gcc2).
* Add rule AddHaikuImagePackages to add a package to the image and rule
IsHaikuImagePackageAdded to determine whether a package has been
added.
* OptionalPackages: Remove all entries that just downloaded and
installed an external package. AddHaikuImagePackages can be used
instead and is used in the remaining entries. Also move the remaining
optional package dependency declarations from
OptionalPackageDependencies here.
* ExtractBuildFeatureArchives: Instead of the URL parameter a package
name must be specified now. This allows to simplify BuildFeatures
significantly, since there's no dealing with URLs anymore. "if" out
the entries that aren't supported yet.
* build_haiku_image: For the packages installed in system and common
resolve their dependencies and download and install them as well.
* Introduce new package attribute B_HPKG_ATTRIBUTE_ID_PACKAGE (valid
only in a repository file) to group the attributes belonging to a
package.
* BRepositoryContentHandler:
- No longer derive from BPackageContentHandler.
- Add hooks HandlePackage() and HandlePackageDone() that bracket the
attributes for a package. This is more explicit and robust than
handlers having to guess when one package ended and the next began.
* BRepositoryCache: Make use of BPackageInfoContentHandler. No need to
duplicate the code for reading a package info from package info
attributes.
DatabaseLocation::OpenOrCreateType(): BNode::WriteAttr() returns the
number of bytes written, not just an error code., so we erroneously
reported an error on success.
Fixes the first part of #9845.
