| 2017-12-13 | hydra: Invalidate derivation caches after each architecture evaluation....This reduces max RSS from 1.3G to 1.0G.
* guix/derivations.scm (invalidate-derivation-caches!): New procedure.
* build-aux/hydra/gnu-system.scm (hydra-jobs): Use it. Add 'format'
call.
| Ludovic Courtès |
| 2017-12-13 | derivations: Don't memoize 'derivation-hash'....This has little or no run-time impact and slightly reduces the memory
footprint.
* guix/derivations.scm (derivation-hash): Replace 'mlambda' with
'lambda'.

Reported by Rutger Helling <rhelling@mykolab.com>.
Fixes <https://bugs.gnu.org/29689>.

* guix/derivations.scm (<derivation-output>, <derivation-input>): Use
'define-immutable-record-type'.
| Ludovic Courtès |
| 2017-06-12 | derivations: Introduce 'read-derivation-from-file'....This avoids the open/fstat/close syscalls upon a cache hit that we had
with the previous idiom:
(call-with-input-file file read-derivation)
where caching happened in 'read-derivation' itself.
* guix/derivations.scm (%read-derivation): Rename to...

into a vhash from path to <substitutable>. Change the returned
procedure to provide a <substitutable> instead of a Boolean.

at <https://lists.gnu.org/archive/html/guix-devel/2017-04/msg00457.html>.
* guix/derivations.scm (build-expression->derivation): Use a string
output port for the expression. This reverts part of

encoding"): New test.

not substitutable anyway, such as profiles.
Reported by Andy Wingo.

not pass 'substitutable-derivation?'.

| 2015-03-25 | derivations: 'substitution-oracle' now ignores sub-trees that are valid....Before that, "guix build qt", when only qt itself is missing, would lead
