Remove last vestiges of darcs from Sage

[kcrisman]

#9257 removed one of the last remnants of the darcs revision control system from Sage. Currently we have

$ grep -r darcs Downloads/sage-4.8/devel/sage/
Binary file Downloads/sage-4.8/devel/sage/.hg/store/00manifest.d matches
Binary file Downloads/sage-4.8/devel/sage/.hg/store/data/changes.i matches
Binary file Downloads/sage-4.8/devel/sage/.hg/store/data/commit.i matches
Binary file Downloads/sage-4.8/devel/sage/.hg/store/data/doc/new.i matches
Binary file Downloads/sage-4.8/devel/sage/.hg/store/data/new.i matches
Binary file Downloads/sage-4.8/devel/sage/.hg/store/data/notes.txt.i matches
Binary file Downloads/sage-4.8/devel/sage/.hg/store/data/sage/misc/darcs.py.i matches

which is fine, all repo history. But apparently we still have a file named sage-mirror-darcs-script:

$ grep -r darcs Downloads/sage-5.0/local/bin/
Binary file Downloads/sage-5.0/local/bin/.hg/dirstate matches
Downloads/sage-5.0/local/bin/.hg/store/fncache:data/sage-mirror-darcs-scripts.i
Binary file Downloads/sage-5.0/local/bin/.hg/undo.dirstate matches
Downloads/sage-5.0/local/bin/.hgignore:(^|/)\_darcs($|/)
Downloads/sage-5.0/local/bin/.hgignore:darcs
Downloads/sage-5.0/local/bin/sage-mirror:rsync -axLH --rsh=ssh --delete -r -v  bin/sage-* bin/_darcs modular:/home/was/www/sage/dist/src/scripts-darcs/
Downloads/sage-5.0/local/bin/sage-mirror-darcs-scripts:cd _darcs/
Downloads/sage-5.0/local/bin/sage-mirror-darcs-scripts:rsync -axLH --rsh=ssh --delete -r -v  * was@modular.math.washington.edu:www/sage/dist/src/scripts-darcs/_darcs/

and it's even still in spkg/bin/sage (the old sage-sage)!

$ grep -r darcs Downloads/sage-5.0/spkg/bin/
Downloads/sage-5.0/spkg/bin/sage:if [ "$1" = '-darcs'  -o "$1" = '--darcs' ]; then
Downloads/sage-5.0/spkg/bin/sage:    darcs "$@"

Needless to say,

$ sage -darcs
/Users/.../sage-5.0/spkg/bin/sage: line 606: darcs: command not found

So let's get rid of these last things. Especially if we might be migrating to git in the mid-range future...

Apply

• trac13122_scripts.patch​ and trac_13122-reviewer1.patch​ to the scripts repo
• trac13122_root.patch​ to the root repo
• trac13122_extcode.patch​ to the extcode repo

Also reported upstream at ​https://github.com/sagemath/sagenb/pull/70

This is all of the stuff that I found that is related to darcs. There are other useless scripts that are unused, but that is for another ticket :).

[kcrisman]

Should we also remove them from .hgignore? Heck, why not. Patch coming up for one of them, and I've submitted ​an upstream pull request which you should be happy I figured out how to do :)

[kcrisman]

Otherwise I guess this is fine. Everything I find now is either directly related to the changes made here (in .hg/patches etc.), part of the revision history, or part of unrelated files (like Pygments and hgext in our Python).

Patchbot, apply trac13122_scripts.patch​, trac13122_root.patch​, trac13122_extcode.patch​, and trac_13122-reviewer1.patch​.

Just FYI, sagenb upstream has just merged the pull request.
