Tom's Work Diary (February 2005)

I've been working on an experiment regarding librifying the 1.3.1 code base.

Here's my week-1 report

Mon Feb 14 12:19 2005

I've implemented changes in 1.3.1 which result in relational table entries and keys and values in associative tables (both libawk data structures) can be shared and are, in fact, shared opportunistically.

Crude initial testing suggests that these changes result in fairly substantial memory savings, especially on large trees.

Speed is roughly unchanged, with a silght degredation. On the other hand, the new code hasn't been tuned and profiling of it suggests that obtaining a net speed improvement is much simpler after these changes than before.

The nitty gritty details are available in a bug report.

There are two new patches (patch-1 and patch-2, in fact) in:

        lord@emf.net--2005/tla--devo--1.3.1


  

which are summarized:

    patch-2
      Remove "libawk/trim.[ch]"
    patch-1
      remove libawk/numbers.[ch]

  

Use of these patches requires the latest revision of libhackerlab in:

        lord@emf.net--2005/hackerlab--devo--1.1

  

(archive locations...)

Merging these changes into branches which wish to remain somewhat in sync with GNU Arch 1.3.1 is recommended. These ought to be low impact changes for all branches.

The short description is that these changes remove the source files matching the patterns:

        ./src/tla/libawk/numbers.[ch]
        ./src/tla/libawk/trim.[ch]

  

The two functions defined in those files have been removed and all callers updated to reflect that.

The changes are documented in detail in the log messages of

Archive: lord@emf.net--libawk-exp-2005
Version: tla--libawk-exp--1.3.1'
Revs: patch-1 ... patch-9

The new system for recording bugs in GNU Arch releases seems to work reasonably well so far and hopefully will be officially in operation before too long. Currently it is still an unofficial experiment, temporarily housed at http://www.gnuarch.org/bugs--devo--2005.

In other news, I am experimentating and exploring a performance question concerning string allocation and copying practices in arch.

Well, tla-1.4pre1 looks terrible: it seems it will not work very well to just "pass through" baz changes as GNU Arch.

Therefore, work on tla-2.0 has been de-prioritized, and work in persuit of a new GNU Arch Roadmap has begun.

Sun Feb 6 13:11 2005 Pika and XL are not dead or even entirely dormant. But to maintain the freedom to work on them, I must concentrate heavily on tla 1.x right now. I have removed links about them from this page because I don't want to take the time to maintain those links properly right now.
