Author: Ludovic Courtès <address@hidden>
Date:   Wed Jan 30 18:59:12 2013 +0100

    .dir-locals.el: Fill at 78 columns.

commit d0840e4a2332de4f6eb4959836de569b413723c1
Author: Ludovic Courtès <address@hidden>
Date:   Wed Jan 30 18:56:20 2013 +0100

    derivations: Memoize `read-derivation'.
    
    * guix/derivations.scm (read-derivation): Rename to...
      (%read-derivation): ... this.

    store: Slightly improve memoization hashing.
    
    * guix/store.scm (open-connection): Call `make-hash-table' with 100.
      (add-text-to-store): Move TEXT first in ARGS, for better `hash'
      results.
      (add-to-store): Likewise, move ST first.

Author: Ludovic Courtès <address@hidden>
Date:   Wed Jan 30 16:30:49 2013 +0100

    store: Remove the `fixed?' parameter from `add-to-store'.
    
    * guix/store.scm (add-to-store): Remove the `fixed?' parameter from the
      public interface.
    * gnu/packages/bootstrap.scm, guix-download.in, guix/derivations.scm,
      guix/packages.scm, tests/derivations.scm: Update all callers
      accordingly.

commit fd060fd30da53f2b0856f6f451f8fd7b8c760d70
Author: Ludovic Courtès <address@hidden>
Date:   Wed Jan 30 16:22:33 2013 +0100

    store: Avoid use of `set!'.
    
    * guix/store.scm (operation): New macro.
      (define-operation): Define in terms of `operation'.
      (add-text-to-store): Define using `operation', and remove now
      unnecessary `set!'.
      (add-to-store): Likewise.
      (add-text-to-store/cached, add-to-store/cached): Remove.

commit 82c38fe64c84fc3febcc5c5aa7fe86454ccaf456
Author: Ludovic Courtès <address@hidden>
Date:   Wed Jan 30 00:37:26 2013 +0100

    store: Micro-optimize `write-string'.
    
    * guix/store.scm (write-string): Optimize to write the length, contents,
      and padding all at once.  This yields a 2% improvement on the
      execution time of "guix-build gdb".
