[asdf-devel] clearing output-translations for a "dumped" image

Thanks for asking about this -- I have not started experimenting with this
yet in earnest.
My main concern is the internals of asdf and Quicklisp itself. Setting
ql:*quicklisp-home* at new image startup time at least does appear to allow
Quicklisp itself to function normally with the new local quicklisp/
directory. The main problem I was having trouble previously was
re-initializing asdf output-translations. They were getting "stuck" to
something hardcoded to an absolute pathname under "/home/dcooper8/.." (or
Windows equivalent) which of course is a no-go for a target delivery
I still have not managed to re-initialize asdf output-translations to the
local home-directory cache of the target user, which is the desired
outcome. The best I have managed so far is to disable output-translations
entirely, so that the fasl's end up near the sources. This is not an ideal
scenario because the target user loses for example the platform-separation
benefits of output-translations.
I have not yet tried Fare's latest advice or looked at re-initializing
output-translations recently. I have to do it very soon however so I will
let you know where things end up.
For the particular case of webserver applications which rely on static
files: I am not yet familiar with Hunchentoot, but Allegroserve has the
concept of publishing static files with functions "publish-file" and
At startup time, our standard restart-init-function (for internal
development and for deployed applications) establishes the local
installation directory, which also determines the location of
ql:*quicklisp-home* -- and we simply re-publish (with Allegroserve's
publish-file or publish-directory operators) the static files. We do not
attempt to have Allegroserve magically reproduce the published locations of
static files in a newly started image - we always explicitly call
publish-file or publish-directory as part of the restart-init-function. I
would think that any library which depends on static files in a similar way
should provide a "publish-resources" function which can be called as part
of a restart-init-function for any image.
Anyway I will keep you apprised of progress in the next days while I am
trying to prepare images for distribution.
