This directory contains bibsort, a UNIX tool for sorting BibTeX
bibliography files.  The contents are:

Makefile        UNIX makefile
README          This file
bibsort.hlp     ASCII text file with formatted manual pages in VAX VMS
                HELP format
bibsort.man     manual pages (nroff/troff input)
bibsort.ps      PostScript version of typeset manual pages
bibsort.sh      bibsort program, implemented as a UNIX sh script using
                nawk, egrep, sort, and, tr.
bibsort.txt     ASCII text file with formatted manual pages
man2ps          UNIX shell script for directing conversion of nroff/troff
                files to PostScript
rofvms.awk      AWK script to convert .txt file to .hlp file

PROBLEMS
========

On HP-9000/735 systems running HP-UX 9.0.1, I had been using nawk via
a symbolic link to /usr/bin/awk.  Unfortunately, when I added the
additional regular-expression patterns [ \t]* to the awk program in
bibsort.sh, this failed: the HP awk complained:

nawk: duplication operator in illegal position

 source line number 9
 context is
        /^[ \t]*@[ \t]*[Pp][Rr][Ee][Aa][Mm][Bb][Ll][Ee][  >>>   ]*{/ <<<  {

This is either a bug in the HP regular expression library, or a
limitation of an older version of HP awk.

I next attempted switching to GNU gawk version 2.15 on this system,
but that failed too.  I finally replaced the /usr/local/bin/nawk
symbolic link to /usr/bin/awk with a compiled version from nawk source
code licensed from AT&T, with files dated December 1991 and December
1987, clearly an ancient version, but it did the trick.

If you need to run bibsort on HP-UX 9.x.x, you probably won't be able
to readily repeat what I did, unless you order nawk sources from AT&T
(about US$100 when I did so), so I suggest installing a modified copy
of bibsort.sh as bibsort, with the patterns [ \t]* eliminated from all
but the initial position in the awk program.  If your bibliography
files have been prettyprinted by bibclean, there will be no whitespace
in the positions matched by those patterns, so the change should not
prove to be a serious limitation.

EFFICIENCY ISSUES
=================

I was unhappy with the runtime performance of bibsort on older
systems, but the availability of fast new systems, and limited
development time, made me put aside the problem until the preparation
of version 0.13 in September 1999, when I finally made a major
improvement.

With a program that depends on another program in a scripting
language, and also on other UNIX commands in a shell pipeline, it is
not immediately evident where the time is being spent.

Fortunately, several years ago, I had prepared a modification of AT&T
awk, called pawk, for profiling awk programs.

I therefore made a copy of the bibsort.sh script and modified it split
the pipeline into separately timeable steps, and used pawk instead of
the old default gawk.

Using a large test bibliography file, available at

        ftp://ftp.math.utah.edu/pub/tex/bib/ieeesoft.bib

the step timings showed that 99% of the time used by bibsort was in
the awk program, and that in that program, a single function,
brace_count(), accounted for 86% of the run time.

I therefore made a test directory with six different candidate
implementations of that function, and ran tests on multiple
architectures with those six tests, and each available awk
implementation.  To further eliminate questions of the effect of
compiler optimization level, on two systems, I built versions of gawk
and mawk with a range of compiler optimization levels.

The results shown in the report below were produced automatically by a
modest awk program from the typescripts of the test runs.  They show
surprising differences in the speed of both the awk implementations,
and the brace_count() function candidates (bc-1 is the algorithm used
in bibsort 0.12 and earlier).  The conclusions from this table are
significant:

        (1) changing the awk implementation can produce as much as a
            factor of 8.4 in the speed of brace_count(), which will likely
            mean as much as a factor of 7 for bibsort;

        (2) changing to algorithm bc-2 can produce as much as a factor
            of 25.6 over the original bc-1 algorithm.

Combined, on most systems, these two simple changes should produce a
speedup of one to two orders of magnitude, which is most gratifying;
see the end of this section for the final story.

For each tested machine in the report below, there are two tables.

(1) The first, labeled ``Algorithm Relative Time'' should be read
    rowwise: 1.00 is the fastest algorithm, and larger numbers are
    that much slower.

(2) The second, labeled ``Implementation Relative Time'' should be
    read columnwise; 1.00 is the fastest awk implementation for the
    algorithm of that column, and larger numbers are that much slower.

All of the major workstation vendors are covered by these tests, and
on some, there is a range of models and operating system versions.

========================================================================

Once the new version (bibsort-0.13) was installed everywhere (using
mawk, which the above table found uniformly the fastest for the
brace_count() function), I went back and made up a second test to
compare the speed of the last two versions on the same test file as
before.

Once again, a modest awk program produced the table below completely
automatically from the test typescripts.  In summary, speedups in
elapsed wall clock time ranged from 8.71 to 20.59, and in CPU (user +
system) time from 1.00 to 30.58.

Even more gratifying is that the greatest wall clock time speedups
were seen on the oldest (and slowest) systems!
