This is a repository for various stuff we're working on for the Workflow SEP (Sage Enhancement Proposal).

This is a script which will ultimately take a (sufficiently recent) Sage release source tarball and convert it into another tarball. The new tarball will be similar to the original, i.e. it will be a source tarball which you will extract, enter the extracted directory, do make, wait a long time, and then end up with a working copy of Sage.

The difference will be that now there will be a single, consolidated git repo sitting in the top level directory. The repo will contain within it the Sage library, the Sage scripts, the Sage root scripts (i.e. the stuff other than SPKGs which you usually see when you extract a source tarball), the Sage external system code (i.e. what is currently in data/extcode).

There will also be no SPKGs in the new tarball. The script will have disassembled each SPKG foo-x.y.z.spkg, repacking the src/ directory into a new tarball upstream/foo-x.y.z.tar.bz2 and merging the internal Mercurial repository into the single consolidated git repo, moving it into the subdirectory packages/, specifically so that its files appear in packages/foo/.

Thus, in this variant of Sage, when installing a package, instead of extracting an SPKG file into a build directory for building, the spkg-install script / patches / etc. and the source tarball will be separately copied (resp. extracted) into the build directory. Installation of actual SPKG files will be emulated - when you run sage -i foo.spkg, the script will disassemble the SPKG as described above, and then install it in its new way.

Besides this, Sage will be generally modified to work with the new paths which all the above necessitate, or, in simple cases, to just copy the files from the new consolidated repository into their old locations whenever you run sage -b.

There used to be a sagedev development tool in this repository. Work on this has been moved to

A file to assist in moving tickets from trac to GitHub. Run it with ./run -- the run file constructs a virtualenv directory so that it can install some dependencies.

directory structure

The proposed directory structure of sage root is:

    sage          # the binary
    Makefile      # top level Makefile
    (configure)   # perhaps, eventually
    ...           # other standard top level files (README, etc.)
        core/     # sage's build system
        pkgs/     # install, patch, and metadata from spkgs
        sage/     # sage library, i.e. devel/sage-main/sage
        ext/      # sage_extcode
        (macapp/) # would no longer have to awkwardly be in extcode
        scripts/  # sage_scripts
    upstream/     # (stripped) tarballs of upstream sources (not tracked)
    local/        # installed binaries and compile artifacts (not tracked)
