Description (last modified by )
This is part of the new layout for git. Since it is not too difficult to separate off this change, I decided making this a distinct ticket was a good idea. SAGE_EXTCODE
will be moved to SAGE_ROOT/devel/ext
, and currently SAGE_LOCAL/share/sage/ext
links to this.
New SPKGS:
- http://wstein.org/home/ohanar/spkgs/elliptic_curves-0.7.spkg
- http://wstein.org/home/ohanar/spkgs/polytopes_db-20100210.p2.spkg
- http://wstein.org/home/ohanar/spkgs/graphs-20120404.p4.spkg
- http://wstein.org/home/ohanar/spkgs/conway_polynomials-0.3.spkg
Installation Steps:
- Add new spkgs
- Apply trac13123_library.patch to the library repo
- Apply trac13123_root.patch and 13123_root_review.patch to the root repo
- Apply #13457 and trac13123_scripts.patch and 13123_bdist.patch to the scripts repo
- Apply trac13123_extcode.patch and 13123_extcode_review.patch to the extcode repo

That will cause me a lot of work in sage-on-gentoo but overall that will make my life easier in the long term. I cannot comment on trac13123_extcode.patch and trac13123_scripts.patch as I don't know the code in there all that well. But for the rest:
- I will need to check the spkg individually for correctness but I assume it will be OK it is the easy part.
- trac13123_library.patch : I am spotting something that I should have reported as a bug a long time ago. In sage/interfaces/gap.py GAP_STAMP is created in $SAGE_LOCAL/bin. This is a no-no if sage is installed globally and accessible by many users. That means all users would need to be able to write to $SAGE_LOCAL/bin to use gap from sage. There is no reason why GAP_STAMP has to be stored there. It should be moved to $DOT_SAGE or possibly even $GAP_DIR. There is a similar problem with qepcad but your patch doesn't touch that particular bit.

Please make it clear in the ticket description which patches have to be applied where.

You should use cp -R
instead of cp -r
(like it was before).
You should deal with upgrading (probably in the new extcode installer): if SAGE_ROOT/data
exists, then move SAGE_ROOT/data/extcode
to SAGE_ROOT/devel/ext-main
and delete the whole directory SAGE_ROOT/data
.

Why don't you
mkdir -p "$SAGE_DATA"
in spkg/install
? That's easier than doing it in the various packages.

Maybe easier, but since I was bumping the versions of these spkgs anyways for upgrading purposes, I figured I would have them take care of their own installation, rather than relying upon the build scripts.

You should expect to see a number of these types of changes from me over the next few months. It should definitely simply things for you as the environment variables SAGE_DATA
and SAGE_EXTCODE
will now be globally respected in Sage.

Since I'm already touching that line, I may as well do it here. If you do end up finishing #5155 in time for 5.1, I'll have to rebase anyway :). (This is under the assumption that this ticket doesn't make it into 5.1, which I feel like is a pretty safe assumption.)
comment:18 Changed 8 years ago by
Thanks. Yes considering that Jeroen wants beta5 to be the last beta before rc our target for both tickets becomes 5.2. I think gap_stamp should go in DOT_SAGE, GAP_DIR seems to be reserved for some gap workspace and it may unwise to put it in there.
comment:19 Changed 8 years ago by
Actually GAP_DIR/workspace-*/
are the gap workspaces, so it should be fine to place in GAP_DIR
.
comment:20 Changed 8 years ago by
You are right, I missed a line or two in the original file. Looks good to me.

Question, why do we sometimes get the SAGE_* variables from os.environ and sometimes from sage.misc.misc? Should we try to be uniform and do it one way only?

I would have it imported from sage.misc.misc
(well actually I would move it to sage.misc.env
, but that currently doesn't exist). I think that I only left one instance of os.environ
between SAGE_DATA
and SAGE_EXTCODE
with this patch (I haven't touched the other SAGE_*
with this patch).
comment:23 follow-up: ↓ 24 Changed 8 years ago by
FYI, looking at the code there might be an issue with using a GAP_STAMP
shared by multiple copies of Sage (I'm not positive, I don't really know the code). For right now I'm using the SAGE_EXTCODE
directory as the GAP_STAMP
.

Putting it in SAGE_EXTCODE is about as bad as putting it in SAGE_LOCAL/bin as it was initially. If you are concerned about multiple sage session running in parallel that's would still be a problem wherever you put it. I am not sure how the file is used but we don't remove it or anything. The real question is: is it actively used by gap? If gap just check for it's presence then it is OK. If it is used then it may have to be unique for each sage session and be cleaned on exit.

Not really, since it removes yet another instance of sage trying to write to someplace it shouldn't be at runtime.
The purpose of GAP_STAMP
seems to be a check on whether it needs to refresh the workspaces. Really, this will all become a moot point if/when libgap is finished.
comment:26 follow-up: ↓ 27 Changed 8 years ago by
As far as I am concerned SAGE_EXTCODE is a place sage shouldn't write at runtime. On a system wide installation that would be a folder that a user is not supposed to own. If a sys-admin install sage under /usr/local/sage-xxx for example, it would resolve to /usr/local/sage-xxx/local/share/sage/ext and as a sys-admin I object that my users have to write something there. Their home folder, tmp and any scratch space set for them is where it should go.
That's my perspective.

I don't write to SAGE_EXTCODE
, I just use its creation for the timestamp that gap wants. It used to be that when you first started sage, it would touch SAGE_LOCAL/bin/gap_stamp
and then use the timestamp of that.
I agree, nothing should try to write to SAGE_LOCAL
or its subdirectories in the long run.
comment:28 Changed 8 years ago by
OK. If we just want a GAP_STAMP file for everyone and in SAGE_EXTCODE it should really be created by the extcode spkg. Is it a file we really need?
comment:29 Changed 8 years ago by
@fbissey
Do you think you are capable of finishing your review of this? (No pressure, just want to know if you can, so that I can find someone else to review it if you aren't able to.)
comment:30 Changed 8 years ago by
Yes, I will hopefully tomorrow. I was a bit down today - but this is important and we should move this.
comment:31 Changed 8 years ago by
Why local/share/sage/data
and not local/share/sage
or even local/share
?
comment:32 Changed 8 years ago by
I would argue for local/share
because the stuff in SAGE_DATA
(apart from extcode) isn't part of Sage. It's part of external packages/databases. So I think it's wrong to use a sage
subdirectory.
Installing databases in local/share/sage/data
is like installing all binaries in local/bin/sage/binaries
and we don't do that either.
For extcode, local/share/sage
makes sense.
comment:33 Changed 8 years ago by
As far as I can tell, this ticket will break upgrading because an upgraded Sage will still have the SAGE_ROOT/data
directory. This could be simply ignored and therefore harmless, but then it needs to be kept inside .hgignore
. Alternatively, you could move SAGE_ROOT/data
or even delete it.
Also, the database packages should depend on SAGE_ROOT_REPO
, otherwise they won't see the new sage-env
when upgrading.
comment:34 Changed 8 years ago by
I can agree with the SAGE_DATA location argument of Jeroen. The only argument against is that for most of them sage is the only application I can think of that make use of it. The splitting of the data is purely a convenience because it ease maintenance. In that case local/share/sage would be most appropriate.

comment:36 Changed 8 years ago by
Sure, my main thing is just removing SAGE_ROOT/data and moving the databases that were there to some place in SAGE_LOCAL.

comment:38 Changed 8 years ago by
- Status changed from needs_work to needs_review
Ok, moved everything to SAGE_LOCAL/share
(added SAGE_SHARE
for convenience), and removed the SAGE_DATA
environment variable.
I also added a bit to SAGE_ROOT/spkg/install
to handle upgrading.
comment:39 Changed 8 years ago by
Some optional/experimental packages use SAGE_DATA
:
- cunningham_tables-1.0
- p_group_cohomology-2.1.2
- database_stein_watkins_mini.p0
- sage-mode-0.7
- database_cremona_ellcurve-20120827
- database_sloane_oeis-2005-12
- database_jones_numfield-v4
- soya-0.11.2.p0
Some optional packages use `$SAGE_ROOT/data':
- database_odlyzko_zeta
- database_symbolic_data-20070206
- database_kohel-20060803
For these reasons, I would keep SAGE_DATA
as synonym of SAGE_SHARE
and also make a symlink
$SAGE_ROOT/data -> local/share
comment:40 Changed 8 years ago by
Keeping SAGE_DATA for a little while as a symlink definitely sound like a good idea. I don't remember explain_picklejar to be removed in trac13123_library.patch before nor do I understand the rational for the removal. Care to shade some light on that?
comment:41 Changed 8 years ago by
In the extcode patch, this comment is clearly wrong:
cp -pR * "$SAGE_ROOT/devel/ext-main/" # Creates new sagenb-main dir

You know that .hg

spkg/install

comment:45 Changed 8 years ago by
- Status changed from needs_review to needs_work
I changed the logic in sage.databases.cremona
since I wrote it, and it when replacing everything, it annoyed me that it wasn't factored appropriately.
I'll see about fixing the extcode spkg-install
(most of the code there comes from a recent version of the sagenb spkg-install
) andspkg/install
, as well as adding a symlink for SAGE_DATA
.
comment:46 Changed 8 years ago by
- Status changed from needs_work to needs_review
I also fixed the commit message for the patches for the sage repos (I had already fixed the commit messages for the spkgs).
comment:47 Changed 8 years ago by
I would really prefer to separate the refactoring of the Cremona database code from this ticket (and then have either this ticket depend on that or the other way around).

comment:50 Changed 8 years ago by

Based on purely reading the patches: positive review modulo my reviewer patches and the Cremona and GAP changes that I mentioned.
In any case, this still needs massive amounts of testing.
comment:51 Changed 8 years ago by
Sorry but I still don't understand the changes in sage/misc/explain_pickle.py and how they are related to the rest of the ticket. It may just be due to a lack of understanding on my part on the working of the pickle jar but the change seems unrelated to the rest of the ticket. Could someone offer me an explanation?

Because the commented out code references SAGE_DATA/extcode

Ok, updated. Changes:

sage.databases.cremona

Tested building from scratch, sdist, bdist, works fine. Positive review to everything not authored by me.
I agree with the deleting of the commented-out code in sage/misc/explain_pickle.py

My reviewer patches still need review.

Looks all clear to me. I didn't really notice that the explain_pickle code was commented out last week, probably because of other stuff going on locally. But still happy that this is related to the rest of the ticket and not a freebie done at the same time.

Ok, everything should work now.
