sage binaries useless for development

[William Stein]

Hi,

Just curious -- is this intentional?

1. Build sage.
2. Type "./sage -bdist ..."
3. Extract the resulting tarball elsewhere
4. Type "make" inside the extracted directory. BOOM! Total disaster.
It starts by trying to download tarballs from the internet, etc...

Has it ever worked?

IMHO nothing beyond 'sage -b' worked in this case...

this is certainly worse than it was.

Yes, because the first version of "sage -bdist" was a 1-liner that
just tar'd up the exact installation. Then we kept removing things to
save disk space...

My unusual, but I think a very important, basic design principle with
sage binaries was that it was *super important* that one could do
development with them. The idea is that a person would play with Sage
(as a user), then with minimal effort switch to doing some development
and contributing. This has clearly been completely lost in the
current binaries. It's also been lost in SageMathCloud -- but I hope
to get it back there (e.g., there could be a link the output of a
docstring or source code of a function in a worksheet, which would
setup a dev environment, and get you going editing that very
function...)

Hi,

I've decided to not worry about this sad loss of functionality.
Instead, for SageMathCloud at least, I'm just going to write a new
"bdist" that will start over by doing (1) tar'ing up a clean Sage
build. I may then add (2) reducing the size a little, if there is
anything obvious, which doesn't break developing Sage. Nobody says
you have to make a tarball of sage using bdist.

Hi

I have to make some decisions for the PPA as well. Here the install is 1) root-owned 2) I just removed .git and .gitignore from the PPA for dpkg-specific reasons (a quilt package fails to build and a native package fails if .git is included). Doing git stuff as root in a /usr/ filesystem over files owend by a debian package is not only not really going to work, it might break your package management hosing your entire system. Some students who use sage but don't know really what file permissions, system-owned locations, paths, or anything linux-shell, might find sudo examples on the internet and blindly try them.

So if the PPA is completely aimed at 1) ease of install and 2) auto-updates via the usual Ubuntu mechanisms and interface then I can remove even more and save a lot of space and bandwidth.

Apart from the "local" folder to I actually need anything else here to run sage?

E.g. can I exclude the huge src folder?

The documentation output is unfortunately still under /src/doc/output. Patches would be welcome!

[Francois Bissey]

Well, where would be a good spot to install it? In sage-on-gentoo
I finally settled in at
/usr/share/doc/sage/$lang
/usr/share/doc/sage/html/$lang
/usr/share/doc/sage/pdf/$lang
Which would correspond to SAGE_LOCAL/share/doc/sage
I also have a mechanism to only build given $lang - with
“en” being mandatory for all purpose.

Sounds good to me!

[Jan Groenewald]

Apart from local and src/doc/output I don't need anything else?

Apart from the language selection, it’s all manual copy at this stage
but if there is will to incorporate stuff “upstream” I am quite willing to
make it happen in a better way.

I just fell overbooked and run over from left (work) and right (kids being
sick in rotation) at the moment so it won’t happen just this minute.

Hi

Apparently I do need something else (than local and doc/src/output):

Hi

Looks like I need build/install and build/deps (checking whether I need only one of them).

Jan

[Jan Groenewald]

Hi

I only need install file not deps.

Also, the new PPA will include only EN and FR docs. Please let me know if PPA users are inconvenienced by this. Maybe we have the time to split the packages but adding back a language is quick.

Jan

Hi

The PPA is now updated, and 32bit has returned (only to Ubuntu 14.04+14.10+15.04 for now; perhaps 12.04 later).

The debs have also almost halved in size.

Regards,

Jan
