Description (last modified by )
What was fixed in #18407 (one week ago) has been broken since :P
That's because the website went mostly down. Also, that new version handles both oldstyle spkg and newstyle spkg.

I insstalled the branch and did "make" which rebuilt a very large amount. Then
./sage standard
gave
Using Sage Server http://www.sagemath.org/spkg HTTP Error 404: Not Found ******************************************************************************** Error contacting http://www.sagemath.org/spkg/standard/list. Try using an alternative server. For example, from the bash prompt try typing export SAGE_SERVER=http://sage.scipy.org/sage/ then try again.
which also failed. SO I don't exactly know what it is that I am supposed to be testing!

Hello !
I insstalled the branch and did "make" which rebuilt a very large amount.
This is suspicious. As you can see from the branch's diff, it only touches one file (i.e. sage/misc/package.py) which is not a dependency of anything as far as I know. I just did a checkout on the branch, and no recompilation was triggered at all.
which also failed. SO I don't exactly know what it is that I am supposed to be testing!
This branch fixes the three functions standard_packages
, optional_packages
, and experimental_packages
defined in sage/misc/package.py
. The script sage standard
script does not call them.
In order to fix sage standard
, it makes more sense to make it call a Sage function that does the job. Previously, standard_packages
ran sage standard
and parsed its output: it would be better to have sage standard
call standard_packages
(without any parsing).
That would require changing the output or standard_packages
, as currently it only returns the list of packages without including the version numbers.

You are right to be suspicious. I was starting from 6.8.beta0, while I think that the branch branched off from 6.7  right? That would explain the extra rebuilding.

Yep, totally. If it can be of interest to you, I use a short bash script that downloads a branch for me, and merges it with my current beta. This way, I never go back to an earlier version of sage and I avoid these problems.
About sage standard
: I added a commit at public/18456v2 that makes it work again, though without the version number.
I can add it to this ticket if you want.

Well, if it doesn't work as is then it cannot get a positive review anyway, so I have changed it to "needs work" and can try again after you have added what is needed to make it work!

You got me wrong: it does not work in the latest beta either. None of the two work. And this ticket fixes one of the two.

Again: if you want I can add this other commit. It makes 'sage standard' call the functions I fix in this branch and display the list of packages (though without the version number).

Sorry, I ran out of time on this and have to go to give an exam (and grade 257 scripts) now. For whoever comes next to the ticket, you will have to explain better why something known not to work is still on "needs review" since I don't understand!

I do not know where you got the idea that this branch breaks anything. If you tell me what, I can surely explain. This branch fixes three functions, as advertised in the ticket's title.

comment:14 Changed 6 years ago by
I believe we should fix sage standard
and similar on this ticket. I think what John is confused about is that this currently fixes the interactive Sage functions (i.e., run from within Sage), not those you run on the shell.
I'm okay with the output on public/18456v2
, but I'd feel more comfortable if someone more experienced with (Sage's) bash scripts (and those who might have an opinion on this) took a look at it before giving this a positive review.

I don't agree with this: ideally, sage standard
, sage optional
, etc., should work without building Sage, or with a partially built Sage.
comment:16 Changed 6 years ago by
Hello guys,
I wrote this fix for sage standard
because that is what everybody seems attracted to, but really my goal here is only to fix standard_packages
(and others) so that I can use them in #18408. And then, in turn, update #18405.
Right now, everything is broken. And I personally prefer by far to have the *_package
functions get ther info directly from the server than parse the output of a commandline tool as it is done at the moment.
Nathann
comment:17 followup: ↓ 18 Changed 6 years ago by
Just to make sure I understand: the original purpose of this ticket was to fix standard_packages
(etc.), but not sage standard
, right? That's fine with me.
For ease of maintenance (and for cleanliness of code, which isn't quite as important), it would be best to not duplicate the work, so it would be best to have standard_packages
rely on sage standard
, or vice versa. My strong preference is for sage standard
to not rely on standard_packages
, since sage standard
should work without having built Sage.
That's my opinion, but I don't feel that strongly about the code duplication, so I personally won't object if this ticket only fixes standard_packages
(etc.) by having it talk directly to the server. I will object if it also fixes sage standard
in such a way that it won't work right after unpacking a fresh tarball.
(In my brief tests, by the way, this does fix the Sage functions as intended. But I haven't looked at the actual changes to see if they make sense.)

+1
My strong preference is for
sage standard
to not rely onstandard_packages
, sincesage standard
should work without having built Sage.
That's what I tried first, i.e. fix sage standard
. But then you have some problems, like undefined environment variables, and you must reparse everything in standard_packages
again.
I thought a bit about making this script dependent on sage, and I actually ended up wondering whether .... we need those sage standard
scripts. Right now they are totally broken, and... Well, if we do not need them then perhaps we should stop maintaining them. They returned outdated information long before they broke.
(In my brief tests, by the way, this does fix the Sage functions as intended. But I haven't looked at the actual changes to see if they make sense.)
I hope that they do ;)

comment:19 followup: ↓ 21 Changed 6 years ago by
Okay. Third fix.
This one fixes the three functions AND the sage standard
commands (which do not need Sage to be compiled). The executable now has a 'dump' options so that there is not much parsing left to do on Sage's side when running that script to get some info.
When it will be reviewed, I will be able to add a cool feature: automatic test of (installed) optional packages.
Needs review again,

I can create a new branch with this change and either of the earlier ones if you want. Or you can do it.
comment:24 followup: ↓ 29 Changed 6 years ago by
 Status changed from needs_review to needs_work
There are no doctests for _package_lists_from_sage_output(..., version=True)
, nor does the OUTPUT
block explain the output in that case.
For version=True
, I would actually propose to change the output format to a list of triples (package_name, installed_version, latest_version)
, where installed_version
is None
if the package is not installed and latest_version
is the newest available version. If, for example, arb2.5.0
is installed but arb2.6.0
is availble, then one such triple would be
('arb', '2.5.0', '2.6.0')
If arb
is not installed:
('arb', None, '2.6.0')
Since this function would be quite different from _package_lists_from_sage_output
, perhaps there should be two functions: _package_lists_from_sage_output
and _package_versions_from_sage_output
or something...

I added a commit that displays column names when 'dump' is not used. The columns change a lot depending on which flags are used, and so this code is not exactly the one you proposed.

I do not mind, you can open a ticket if you need this feature.
Since this function would be quite different from

and_package_versions_from_sage_output

Two private functions that do almost the same job? Let's keep things simple, one is enough.
