guix.git/guix/memoization.scm, branch master Personal branch of https://git.savannah.gnu.org/cgit/guix.git/ for implementing 'guix deploy'. https://www.git.jakob.space/guix.git/atom?h=master 2017-12-13T22:11:53Z memoization: Add 'invalidate-memoization!. 2017-12-13T22:11:53Z Ludovic Courtès ludo@gnu.org 2017-12-13T13:59:48Z urn:sha1:d1f01e48457f8cac9e64fb9f890332d5d93f430e * guix/memoization.scm (%make-hash-table*): When not profiling, add the new table to %MEMOIZATION-TABLES. (invalidate-memoization!): New procedure. memoization: Profiling support keeps track of lookups and hits. 2017-12-12T17:11:22Z Ludovic Courtès ludovic.courtes@inria.fr 2017-12-12T13:52:17Z urn:sha1:6c80641d54a95f2da95e480a4a746761d25161e9 * guix/memoization.scm (<cache>): New record type. (define-lookup-procedure, define-update-procedure): New macros. (cache-ref, cacheq-ref, cache-set!, cacheq-set!): New procedures. (cached/mv, cachedq/mv, cached, cachedq): Use them instead of 'hash-ref' and 'hash-set!'. (%make-hash-table*): When 'profiled?' returns true, return a <cache> object. (define-cache-procedure): Adjust to show cache lookups and hits. memoization: Add profiling support. 2017-12-12T17:11:22Z Ludovic Courtès ludo@gnu.org 2017-12-11T20:43:54Z urn:sha1:252c4083779a488c86e74362b4f3bb4bf927cc67 * guix/memoization.scm (%memoization-tables): New variable. (%make-hash-table*, show-memoization-tables): New procedures. (make-hash-table*): New macro. Add top-level call to 'register-profiling-hook!'. (memoize): Adjust to pass the resulting procedure to 'make-hash-table*'. (%mlambda): Likewise. memoization: (mlambda () ...) allows for inner 'define'. 2017-09-03T21:36:17Z Ludovic Courtès ludo@gnu.org 2017-09-03T21:29:11Z urn:sha1:e3c83a7cd3618a87d74e58973dcd82e560e2da97 Previously (mlambda () (define foo 2) bar) would trigger a syntax error. * guix/memoization.scm (%mlambda): In the zero-argument case, move BODY... to a lambda to allow for inner 'define' and such. memoization: Micro-optimize code produced by 'define-cache-procedure'. 2017-03-16T21:50:15Z Ludovic Courtès ludo@gnu.org 2017-03-16T12:41:51Z urn:sha1:146db52a188b871769d9512867aa7f409f37dbac * guix/memoization.scm (%nothing): Remove. (define-cache-procedure): Make '%nothing' a local variable, with a literal list. Add (guix memoization). 2017-01-28T17:55:20Z Ludovic Courtès ludo@gnu.org 2017-01-28T15:33:57Z urn:sha1:f9704f179a5160013c4a401dce3761714bba8e72 * guix/combinators.scm (memoize): Remove. * guix/memoization.scm: New file. * Makefile.am (MODULES): Add it. * gnu/packages.scm, gnu/packages/bootstrap.scm, guix/build-system/gnu.scm, guix/build-system/python.scm, guix/derivations.scm, guix/gnu-maintenance.scm, guix/import/cran.scm, guix/import/elpa.scm, guix/modules.scm, guix/scripts/build.scm, guix/scripts/graph.scm, guix/scripts/lint.scm, guix/store.scm, guix/utils.scm: Adjust imports accordingly.
