Description (last modified by )
Put the text files in $SAGE_ROOT
, and also the text files in spkg, under revision control. (See the discussion at the end of #9351.)
Here are the instructions:
 apply the patches trac_9433sagerepo.2.patch and trac_9433scripts.v5.2.patch
 move the attached file hgignore to
$SAGE_ROOT/.hgignore
(note that this is a new file)  move the attached file rootspkginstall.v2 to
$SAGE_ROOT/spkg/rootspkginstall
(note that this is a new file)  apply 9433_install.diff to
$SAGE_ROOT/spkg/install
 apply 9433_deps.diff to
$SAGE_ROOT/spkg/standard/deps
Then from $SAGE_ROOT, run the attached script 9433_hg_script.sh to create the Mercurial repository.

A little explanation: this patch creates a directory "otherscripts" in SAGE_ROOT/local/bin. This new directory contains a brief README.txt and also subdirectories "root" and "spkg". "root" contains the text files from SAGE_ROOT. The only one with any changes is README.txt which explains how these files are under revision control. Similarly, "spkg" contains various text files from SAGE_ROOT/spkg, and the only one with any changes is README.txt.

This probably needs to be rebased. When people are ready to look at it, let me know and I'll see what I can do.
comment:4 Changed 10 years ago by
New approach, after a discussion on sagedevel: create a new repo at the top level tracking the appropriate files. I'm attaching a new version of the patch for the scripts repo. Someone  the release manager, I guess  also needs to create the top level repo, because I don't know how to do this in such a way that it can be posted on a ticket. Here are the instructions:
 move the attached file "hgignore" to SAGE_ROOT/.hgignore
 cd $SAGE_ROOT
 hg init .
 hg add .hgignore COPYING.txt README.txt makefile sage sagepython
 cd spkg
 hg add README.txt gen_html install pipestatus
 cd standard
 hg add README.txt deps libdist_filelist newest_version
 hg add notes.txt numeric24.2.txt
(I don't know if we really need these last two files, but this is probably not the ticket for making such decisions.) Finally, do
 hg commit
When you run "sage sdist ..." it should add a tag for the new version of Sage.
This does not create a new spkg for the files in SAGE_ROOT, since those files have to be in place when you unpack the sage tar file. But it creates the repository so that people can post patches to the trac server, etc.

Looking with my eyes, this looks good. I don't have time to test right now. The test would be to take a clean Sage, do the above, then do "sage sdist ..." and make sure that in the sdist the above is all still there.

This works for me, but other people should definitely look at it carefully.

This probably needs work: how will it work with "sage upgrade"?
comment:8 Changed 10 years ago by
 Description modified (diff)
Here's a new version of the patch for the scripts repo. I think this should deal with upgrading: the script "sageupgrade" now runs "sage hg branch" from SAGE_ROOT, and if this fails, it assumes that there is no Mercurial repository and creates it.

In sagesdist, where you have # copy sage root repo over
, why not just clone the repo? That will take care of copying all the necessary files, and if we add or remove files tracked by the repo, we won't need to mess with sagesdist. I'm thinking that something like
cd $SAGE_ROOT hg clone pull . DEST_DIR
Using pull means that it doesn't use hardlinks in the clone; I *think* there would be no problem with using hardlinks, but it's unlikely to make a big difference. The clone will include a hgrc file that points to where it came from: it would look something like this:
[paths] default = /home/foo/sagewhatever
We could simply delete the file, or just leave it, since it would not negatively affect anything (except running hg pull
from SAGE_ROOT, which you wouldn't do anyway).
So, all the cp p
lines could be just
hg clone pull . $TMP rm $TMP/.hg/hgrc
and files added or removed to the repo would get copied correctly without changing any scripts.
comment:13 Changed 10 years ago by
Note that if you use "hg clone ..." to copy the repo, you have to do it earlier in the process: it apparently needs to be done with an empty directory, so in sagesdist it is now done right after creating $TMP.

Right, I didn't do this right. In the new patch, the root repo is not modified at all by sagemake_devel_packages; instead, sagesdist clones it, tags it, and commits the new tag, while sagebdist just clones it.
I also noticed
 SAGE_ROOT/ipython and SAGE_ROOT/sageREADMEosx.txt are missing from the new source and binary distributions.
The missing ipython directory was an oversight. I think I've fixed it. The missing sageREADMEosx.txt was intentional: this should only be included for binary distributions on OS X, and its presence there is taken care of by sagebdist:
if [ "$UNAME" = "Darwin" ]; then ... cp sage/local/bin/sageREADMEosx.txt README.txt ...
Perhaps we can close #6938 if this gets merged?

This was intentional. Before this, the file sagepython was stored in the scripts repo and then unpacked to the top level. I'm not sure why this was done, but I wanted to keep the end result as close as possible to what it was before.

As one of the people involved on that ticket, that is fine. The problem is that #6938 does not currently have positive review! So I think that would be necessary first, or something else indicating that the solution proposed there is correct. Maybe 'merge' that ticket at the same time as this one, for whatever it's worth.
Sounds like you agree :) In fact, notice that once that is removed, that file will only appear ABOVE the SAGE_ROOT directory, in the place a normal README would occur in a dmg or bundle, so it does work properly (I've tested this numerous times
comment:20 Changed 10 years ago by
 Description modified (diff)
I realized there was another problem with the previous patch: while it would work when upgrading from a Sage build with no root repo, it wouldn't do anything when upgrading a Sage build with an existing root repo. The new patch constructs a sage_root spkg file, but this file only gets used during upgrading. So it is installed in the script "sageupgrade", but it does not appear in spkg/standard/deps.
comment:21 Changed 10 years ago by
 Status changed from needs_review to needs_work
This still doesn't deal with upgrading very well. I need to think about how to do this and work on it for a while in a place where I have a better internet connection. I may have something in a few days. Meanwhile, if anyone has suggestions for how to deal with upgrades, I would like to hear them. The issues:
 currently, I don't even know what happens with "sage upgrade ..." if SAGE_ROOT/makefile is changed, for example. Does anything happen?
 does it matter whether we install the new sage_root spkg before or after the sage_scripts spkg? The patch here affects the sageupgrade script, but the new version won't get run during an upgrade anyway.
 is it good enough to just install the new sage_root spkg? I think it might be, but I might be confused. Anyway, I think I need time to play with it and test it out.
comment:22 Changed 10 years ago by

 Status changed from needs_work to needs_review
This seems to work for me, with one slight glitch: if I run "sage upgrade" on a copy of sage which does not yet include the root repo, it lists the spkg's to be upgraded and asks me "do you really want to continue", then it does some stuff, and then it lists just the root_repo spkg and asks me again if I want to continue. The issue is that, before it has installed some of the upgraded packages, it doesn't know what to do with the root_repo spkg, so it doesn't get installed the first time through. I don't see any way around this, but it's a onetime problem.

Should sageREADMEosx.txt
be ignored (i.e. not be under revision control)?
Also a candidate for renaming (README.MacOS_X.txt
or alike).
From the attached hg_script
:
... $hg add .hgignore .hgtags COPYING.txt README.txt makefile sage sagepython cd ipython $hg add *.py ipythonrc* ...
sagepython
and ipython/
should IMHO be in .hgignore

It shouldn't be present at all, and with the patches here, it isn't. See #6938 and also my comment above. (It should only appear in the parent directory of SAGE_ROOT when you make a dmg file on a Mac.)

This is another change on this ticket: these files are now tracked in this repo, not in sage_scripts anymore. Actually, I don't know if ipython was tracked anywhere, but now it is. I don't know who chose to include sagepython in the toplevel directory, but since it's there, it should be tracked properly. (It's a simple enough script I don't mind having two copies of it.) I personally don't see the point of it and think it should be removed, but that should probably happen on another ticket. Or maybe it should be a link to local/bin/sagepython?

That definitely used to be in this directory, filename HISTORY.txt

It might be an onus on the release manager to create the notes *before* the release is made, though  usually that takes a little time, and then it somehow gets added to the official version at sagemath.org (and a few other places?). The problem is that this isn't fully automated yet.

Doesn't have to be under revision control (i.e. could be in .hgignore
); it IMHO shouldn't be too lengthy, perhaps just contain the most recent changes (e.g. tickets merged since last final, with a reference to a complete version elsewhere).

I think the release notes as in the announcements are meanwhile fully automatically generated by a script. I just wonder if these are really "human"(means user)readable, if we intend that.

The hard part is, but at least in theory the "known issues" and "new features" sections and things like that are supposed to be humangenerated. mvngu used to make great categorized ones, but likely hasn't had the time lately. I think they are more humanreadable than some I've seen in other programs, though :)
comment:33 Changed 10 years ago by
I think that for release notes, we could just have a document which says something like "Please see http://sagemath.org/mirror/src/changelogs/sage$VERSION.txt for a list of recent changes." Or we could use the link "http://sagemath.org/mirror/src/changelogs/" and then we wouldn't have to update it. This also provides easy access to older changelogs (which the $VERSION.txt doesn't, and notice it's just a text file  no links to the parent directory or older changelogs). Opinions? We could also add the link "http://wiki.sagemath.org/ReleaseTours/", although this hasn't been updated in a while.
I like the generic option better. But notice that this file won't be autogenerated by "sage sdist" or any other script, and it should probably be under revision control. This is not the right ticket for adding new files to the top directory, or for modifying existing files, so I think this should go elsewhere.
I also agree that a VERSION.txt file is a good idea. Since we can automatically generate this, and since it shouldn't be under revision control, I think we can do it on this ticket. It should just require modifying sagesdist and sagebdist. I'll try towork on this some time soon.
comment:34 Changed 10 years ago by
As a first step, just add VERSION.txt
to .hgignore
(here). ;)
My intention (perhaps as a developer) regarding "release notes" (whatever the file is called) also was not to have to search trac or some web page(s) (or query Mercurial) just to see which tickets have recently been merged...
For users, of course a more abstract description would be better (bugs fixed, packages newly included or upgraded, new features etc.)
comment:35 Changed 10 years ago by
I've opened up #9922 for adding release notes. For VERSION.txt, I think we (meaning me) should do the whole thing on this ticket: add it to .hgignore
, create it in sagesdist
, and make sure it gets copied by sagebdist
, or else the whole thing should go on another ticket. If I don't get to it on this one, then I'll open a ticket describing the steps (including adding it to .hgignore
)  I don't really see the point in doing one piece of it here.
comment:36 Changed 10 years ago by
Should we update VERSION.txt
after successful upgrades? Or maybe have separate fields for the original version (and whether it was a binary) and the current version? Or even keep a brief upgrade history?
comment:37 Changed 10 years ago by
I've attached a new version of hg_script which rename 'makefile' to 'Makefile' if it hasn't already been done. (I thought I also had to modify rootspkginstall, but I don't think I do: once the repo has been made via hg_script, it will have 'Makefile' in it, not 'makefile'.)
I also think mpatel has a good point about VERSION.txt. I think there are possible design decisions to be made about how to create that file, what should go in it, how to modify it, etc., so I think it should go another ticket. It could piggyback on #9922, I think. I'm going to change the description of that ticket to include this.
comment:38 Changed 10 years ago by
Regarding all this VERSION.txt stuff, I think we should stay on task here. This ticket is about putting existing files under version control. Adding new files "while we're at it" is, IMHO, an unnecessary distraction.
Once SAGE_ROOT is in a Mercurial repo, we can add new files by just creating a ticket, attaching a patch, and getting a positive review. Let's get that repo there first!

Also, test d foo

There are some quotes missing at the end of sagemake_devel_packages

Quoting $OPT
currently works, since it is
OPT="pPR"
but it is a bad idea to omit the dash(es) in OPT
and prepend it to the expansion.
I.e., it should be
OPT="pPR" ... cp $OPT ... # NOT quoted ... cp L $OPT ... # also NOT quoted
And I'd suggest renaming OPT
to CP_OPTS
.

I'm not sure what you mean by "base packages". The sageupgrade
script will certainly upgrade the sageroot spkg. Let's see, the sageupdate script will download any new spkg, including any sageroot spkg. Then it gets installed in sageupgrade before the other spkgs, in case it changes deps or spkg/install.
Should I create an upgrade path on sage.math? I may wait a day or two for the disk situation to settle down...
Re the "pipestatus" command, I'm going to leave it as is and see what happens during testing. (When I tested a month ago or so, the sageroot spkg got upgraded, and I vaguely remember checking that the log file had the right name, but I'll test again.)

I'll fix that. You mean messages like "Error building the sage source code package" or "Error copying sage root repository", right?
Yes.
Btw, why aren't base packages subject to upgrading? (I would have expected the root spkg there.)
I'm not sure what you mean by "base packages".
The packages /files in spkg/base
, also referred to by $(BASE)
in the Makefile (deps
).
The
sageupgrade
script will certainly upgrade the sageroot spkg.
Yes, of course. (sageupdate
currently doesn't attempt to upgrade anything from spkg/base
.)
Should I create an upgrade path on sage.math? I may wait a day or two for the disk situation to settle down...
I have no opinion on that.
Re the "pipestatus" command, I'm going to leave it as is and see what happens during testing. (When I tested a month ago or so, the sageroot spkg got upgraded, and I vaguely remember checking that the log file had the right name, but I'll test again.)
This again just referred to spaces in SAGE_ROOT. (My last suggestions would work with such.)

Here are new versions; the only difference with any content (i.e., other than capitalization, I think) is from sageupgrade:
./pipestatus "sagespkg $ROOT_REPO 2>&1" "tee a $SAGE_ROOT/spkg/logs/$ROOT_REPO.log" +./pipestatus "sagespkg $ROOT_REPO 2>&1" "tee a '$SAGE_ROOT'/spkg/logs/$ROOT_REPO.log" + +if [ $? ne 0 ]; then + echo "Error installing Sage root repository." + exit 1 +fi
I don't know why base packages don't get upgraded. That's for another ticket.

I meant so that people could test "sage upgrade". I'll do this pretty soon.

I rebased the above two patches. The main Sage repo one is fine, but the scripts patch had rejects on some huge hunks and it took a while to manually put them in. Someone should check over the "rebased" patch and make sure I did everything correctly.

Hi Dan,
Thanks for working on this. The Sage repo patch looks good. Skimming the scripts patch, the only issue I see with the rebasing is that I think $PKGDIR should be quoted in the following (this is lines 3941 in sagesdist):
cp "$SAGE_ROOT"/local/bin/sagespkg $PKGDIR/base/ cp "$SAGE_ROOT"/local/bin/sageenv $PKGDIR/base/ cp "$SAGE_ROOT"/local/bin/sagemake_relative $PKGDIR/base/
I'll look at this more carefully when I have time.

I'm working on providing an upgrade path (or two) for testing. I'll post here when I have links.

Okay for testing upgrading:
./sage upgrade http://sage.math.washington.edu/home/palmieri/misc/9433/sage4.6.1.9433.alpha0/
This first upgrade path is just a vanilla version of 4.6.1.alpha0, plus the new root repo.
./sage upgrade http://sage.math.washington.edu/home/palmieri/misc/9433/sage4.6.1.9433.alpha1/
The second upgrade path contains everything from the first one, plus a change to the toplevel README.txt file. This is so we can test upgrading to a plain root repo, then from there to a modified version. So upgrading to "...9433.alpha0" followed by "...9433.alpha1" should work, as well as just upgrading straight to "...9433.alpha1".
I think that if you upgrade from a version with a Sage root repo to either of these, you may be asked twice if you want to upgrade. I mentioned this issue above.
comment:63 followup: ↓ 65 Changed 10 years ago by
One issue: if you upgrade a version of Sage containing "makefile", then you end up with both "makefile" and "Makefile" when you're done. We can just delete "$SAGE_ROOT/makefile" when running the rootspkginstall file. That's easy enough to do; is it the right solution?
comment:64 Changed 10 years ago by
Hmmm, this doesn't work for upgrades from older versions (<=4.5), and as you mentioned, behaves strange on newer versions >=4.5.1.
We have to download spkg/install
(and I'd prefer the rest, too) in sageupdate
(the Python script).
What's currently newly made in sageupgrade
should be moved to that file, which is in any case the fresh, downloaded one. There we have to make a distinction on if we are upgrading.
If so, spkg/install
should then install the root repo (preferably without overwriting itself, but the root repo should, i.e. must, contain exactly the same file), since our "real" Makefile spkg/standard/deps
doesn't (though I don't know why you don't want to put the root spkg there).
Btw, it would be better to also have sagespkg
in the root rather than the scripts repo; or download an identical copy (from the scripts repo) along with install
, deps
etc.
This way we would always do the whole build with the new one, and not switch the version during the installation (after the new scripts spkg has been installed).
Another reason to keep the repos separate, and not as Robert B. suggested on sagedevel, merge them all into an even larger, monolithic one.
(To avoid trouble with getting overwritten, a script can always clone itself and then exec
this copy, passing it a parameter such that it knows if it's the clone or the original, similar to fork()
. We should IMHO do this for a few scripts involved in upgrading and the build process. Therefore, the chain or stack of called rather than exec
'ed scripts shouldn't be deep.)

Well, then hg pull
would simply be a noop. But we should check the exit codes of the commands in rootspkginstall
(hg
and cp
) anyway.
hg incoming <source repo>
returns 1 if there's nothing to pull, 0 if there are changes to pull, other values on errors, so you could change it to:
... if [ d "$TARGET"/.hg ]; then # Merge the repository, rather than overwrite changes that the # user may have made. cd "$TARGET" hg ci # Don't know if we should check in unconditionally, # so perhaps move this below the ifeliffi. # should check for errors here hg incoming "$CUR" # perhaps redirect output if [ $? eq 1 ]; then # No changes to pull exit 0 elif [ $? ne 0 ]; then # Some error, report... exit 1 fi # $? = 0: Changes to pull... hg pull "$CUR" hg merge tip hg ci m "Checkin during upgrade of Sage." hg update # Add error checks above, too. else ...
(Or you could add a rule to deps
that tests its presence / the need to pull first, before calling sagespkg
. But if we one day generate deps
, this would be less optimal.)

If we put it in deps, I guess it gets installed at the end? I was tempted to make it part of BASE, but then during an upgrade, any changes to the Sage root repo would mean that everything would be rebuilt, which would be annoying. The only issue is if there is an upgrade to a script like "pipestatus" which is in the root repo, is used in the upgrade process, and is not downloaded in sageupdate.

I'm not sure what you mean: the file "rootspkginstall" is completely new to this ticket, and is not part of any preexisting repo. So there's nothing to patch. I'm flipping this back to "needs review".
Regarding #10231, I'd like to see more discussion on sagedevel about it. I know that leif disagrees, but I'm also interested in the idea of combining the various nonroot repos (scripts, examples, extcode, and the main Sage library) into one. It seems like the Sage community should decide about both of these issues in sagedevel rather than on a trac ticket.

Well, there was some discussion at http://groups.google.com/group/sagedevel/browse_thread/thread/cc30eaf87b283881/c2290991827fec9c?hl=en_US&#c2290991827fec9c.
Personally, I simply don't see the need for merging sage, sage_scripts, extcode, examples,... into one big spkg. So there is some disagreement on this. But this disagreement should not stop us from doing something to which most people seemed to agree: not repackaging extcode and examples with every new Sage version (which is exactly what I want to accomplish with #10231).

Not too much discussion of that proposal. You suggested it, and a few people liked the idea. On the other hand, a few people made the counterproposal to merge all of the repositories. If we end up merging everything, then doing #10231 first will make more work: whatever is involved in that, and then the merge, as opposed to just the merge. So I'd like to see more of a consensus about which direction to go before putting much effort into #10231.
This ticket seems like a separate issue, and regardless of everything else, the Sage root repo should remain separate from the others, because it should already be installed when you unpack the Sage tar ball. Perhaps its role should increase, including files like sageenv and sagespkg, but that's for another ticket. I hope this ticket can get a positive review soon, and then if anyone feels like working on #10231 (or on a possible merge of the repos), they can base their work on this ticket and other tickets which touch sagesdist and related files.

I would prefer to have to do this only once, not once for this ticket and once for every followup ticket.
I think I don't understand. Once there is a SAGE_ROOT repo, then any followup ticket can just have a patch which needs to be applied to that repo, as opposed to manually patching spkg/install
or Makefile
or whatever.
For the particular change you have in mind, it requires modifying various scripts (like spkginstall, but maybe others?) in local/bin, and it could possibly be complicated. It seems safer to do things incrementally, first setting up the new repo, then on a later ticket making further changes.
(I also have a heavy teaching load right now, so I won't have much time to work on this. I can try to fix bugs with the current implementation when anyone finds them, but I don't think I can work on any major modifications, like dealing with the spkg/base repo.)

I'm with John here: Its easy to generate a patch that adds a new file to the sage_root
repository. You don't have to do anything else for updates, the change will automatically make it into the next sage_root
package. No more manually digging around to make a new source distribution :)

And indeed, this is the Sage way of doing things  perfect being the enemy of things ever happening in the open development, open source model.
I'd also like to put in a plug for sageREADMEosx.txt finally being removed from $SAGE_ROOT. Apparently #6938 never got 'merged'...> (I also have a heavy teaching load right now, so I won't have much time to work on this.

In general, I completely agree with your sentiment: too many times a patch has not been finished because it was not the "optimal" solution. However, this only applies if the halfwayimplemented patch makes the situation better.
For this particular ticket, I feel that having a halfwayimplemented sage_root repository is strictly worse than having no sage_root repository at all. The situation for merging SAGE_ROOT patches is already complicated enough (but I can manage) and I'm afraid the current patch on this ticket will make it only worse.
This is not a ticket I want to "rush" into Sage.

This ticket has been worked on for 7 months and has almost 100 comments ;)
And every time I want to change something on this ticket I need half a day to rebuild sage, manually make half a dozen changes, test the source distribution.
I can make the changes you wanted in comment:91 but there are a bunch of other files I want to move to the sage_root
repository as well. Some of them might need some discussion on sagedevel first. How many more months should we wait until the main makefile is under revision control?

In what way is the SAGE_ROOT repo "halfwayimplemented"? With these scripts and patches, the repo will exist and work for upgrades and new builds.

Maybe you can manage  but there's plenty of evidence that other release managers can't. Changing files in SAGE_ROOT currently takes a long time and is an extremely brittle process; why continue in this way?
And even if there's no trouble actually changing files, we still have no version control for our basic makefile, README, and executable script. The only way to track changes is to download tarballs, unpack them, and compare files. Think about it: neither the basic file with which we build Sage (the makefile) nor the basic file with which one runs Sage (SAGE_ROOT/sage) are under any version control! That is crazy. Imagine if Firefox shipped with their "firefox" script not under version control.
and I'm afraid the current patch on this ticket will make it only worse.
Right now to change the README:
 make a backup copy
 make your changes
 manually run
diff u
to produce a patch  upload both the new README and the patch to a ticket
 upon positive review, hope that the release manager replaces the README file correctly and does
sage sdist
in the right directory
With a SAGE_ROOT repo:
 use the same procedure that one uses in the Sage library to produce a patch.
 release manager uses same procedure as for the Sage library to merge the patch.
Perhaps it's only me, but the current situation seems far worse.
Please, let's create the SAGE_ROOT repo and argue about merging repos after they actually exist.

Wrong, because the README
is actually already in a different repository, namely sage_scripts
. This is the issue of duplicate files that I mentioned above.

After applying the patches here, README.txt will be in the SAGE_ROOT repo, not the scripts repo. The full list of files which will be tracked:
.hgignore .hgtags COPYING.txt README.txt Makefile sage
 in the ipython directory: *.py, ipythonrc*
 in the spkg directory: README.txt gen_html install pipestatus rootspkginstall
 in the spkg/standard directory: README.txt deps libdist_filelist newest_version

The SAGE_ROOT/ipython
directory is created during the Sage build process, so I don't think it should be part of the SAGE_ROOT
repository.

 Description modified (diff)
I'm marking this as "needs review", but consider this patch experimental.
