Is anyone on this list aware of functions to save and restore emacs
state, including all buffers (both temporary and file-related),
command history, kill-ring, and loaded emacs libraries?
I frequently want the ability to switch from one emacs session to
another, sometimes after a version upgrade, and other times between
different machines. Because my emacs sessions frequently run for many
months, the state is complex, and painful to reconstruct. Computers
should work for people, not the other way around, so it would be nice
to do something like this:
M-x save-state<RETurn>
Filename: $HOME/emacs.state
M-x restore-state<RETurn>
Filename: $HOME/emacs.state

Does desktop-save work?

Thanks! M-x desktop-save and M-x desktop-read get most of what I
want.
Three things that I noted are missing are (1) a time-ordered list of
loaded libraries, (2) the kill ring, and (3) the command history.
The search history is saved, and that is certainly nice.

See also `savehist.el' and option `save-additional-variables'.
Try vars `load-history', `kill-ring', and `command-history'.

Nitpick: `load-history' is not a variable you should touch in this
way, tho (e.g. it won't magically load the corresponding libraries).
Also he may also want to use `desktop-globals-to-save' instead of
savehist.el.

Agreed.

I use session.el to get history saving.

This said, the redundancy between the two is a bit annoying, tho I'm not
sure how to get rid of it.

FYI, this was discussed in a fair amount of length on emacs-devel:

The problem was discussed, but not the (potential) solution.

True. This wishlist occurs to me, to keep in mind when looking for a solution:
1. Factoring out some code commonality would be good (modulo other wishes).
2. Users should be able to save histories without necessarily saving all the
other desktop stuff.
3. Users should be able to save other desktop stuff without necessarily saving
histories.
4. Users can save multiple desktops, which should be able to have different
saved histories. IOW, a given history variable, e.g., `file-name-history',
could have a different saved value in different desktops.

Agreed. I think the way forward is to restructure the code so
desktop.el can use savehist-mode (e.g. so it can tell it where/when to
save the history).
There's a similar issue with saveplace.el (again, with slightly
different semantic but no good reason why saveplace.el can't provide the
needed flexibility for desktop.el to use it and let the user choose
between the usual desktop.el semantics or the usual saveplace.el
semantics).
