The point between the compilation and copying gap onto the system proper is what takes time. Apart from the indexing issue I suspect one the helper from portage (the system package manager) is suboptimal for that particular use case. If gap had a proper "make install" target (that respect DESTDIR) it may improve the install time greatly.

There are two gap packages, xgap and pargap, which can not be loaded from GAP with LoadPackage command. Instead, they have own shell scripts to start GAP in a specific way.

That's a point were I think I should chip in some info. When sage moved to gap 4.5+ I was in pain making a new ebuild for sage-on- gentoo. Initially I was just installing the full gap instead of a trimmed version. Installation takes ages. I have now trimmed things a little bit but it still take ages - but still an improvement. I had to very quickly blacklist xgap, removing it altogether. In gap 4.5.x it would automatically load when gap was started in sage and cause sage to hang. It took us a little while to pinpoint it. https://github.com/cschwan/sage-on-gentoo/issues/189 in particular https://github.com/cschwan/sage-on-gentoo/issues/189#issuecomment-12587392 Installing the rest had an effect on a couple of doctests if I remember correctly but nothing dramatic.

At the moment, BOB performs a new install, so it's not suitable to update an existing GAP installation. That is a suggestion for the future perhaps, for BOB or for any other package manager for GAP that may appear. I was recommending BOB in response to Samuel saying "... alternatively, would it be possible to have a separate full GAP install?". If you prefer just to add some more packages to the GAP version that is built as part of Sage, and do not want all of them for some reasons, then it would be great at least to ensure that all packages listed under the 'PackagesToLoad' user preference in lib/package.gi are included: default:= [ "autpgrp", "alnuth", "crisp", "ctbllib", "factint", "fga", "irredsol", "laguna", "polenta", "polycyclic", "resclasses", "sophus", "tomlib" ], But the actual list will be larger, since these default packages have some dependencies, as can be seen from the GAP startup information: ┌───┐ GAP, Version 4.7.5 of 24-May-2014 (free software, GPL) │ GAP │ http://www.gap-system.org └───┘ Architecture: x86_64-unknown-linux-gnu-gcc-default64 Libs used: gmp, readline Loading the library and packages ...

[sage-devel] propcalc vs sat
Hi, looking at this ask question : http://ask.sagemath.org/question/24024/satisfying-assignments/ i tried to turn a propcalc formula into a sat (DIMACS) one since those two sage modules are intimately related. The only candidate i found on the propcalc side is the .satformat() but then i could not figure out how to use this string to create a DIMACS instance. Looking at the DIMACS class, it seems there are only methods to write DIMACS files, but i could not find anything to read such files. Any hint ?

Re: [sage-devel] Re: One-click installer for Vbox+Sage
No I mean unix passwords are not known. Servers are not running by default. No open door that I know, no obvious way to get hacked easily. Not even me remember built in passwords. VM starts to desktop, so you can change unix passwords and start sage notebook/server with physical access, which was the planned use case. Sage notebook admin password is asked for at first start, nothing built in. But this is an old version and design choices may vary. Whenever building a new VM it may be NAT and headless, as easy as possible, windows friendly. Nothing to be scared. kind regards On Tuesday, September 2, 2014 3:03:39 PM UTC, Volker Braun wrote: > > You mean the notebook password?

Re: [sage-devel] Re: One-click installer for Vbox+Sage
That depends on whether the virtualbox networking is set to NAT or bridged mode. I'm strongly in favor of NAT as default when providing a VM with known password(s). Of course we could have a UI that locally asks for passwords and then changes them in the VM before making it available on the network, but thats probably for later.
