* 0.01: initial version
1999-11-30 James Manning <jmm@users.sf.net>
* 0.06: tiobench.sh fixes and block improvements
1999-12-01 Mika Kuoppala <miku@iki.fi>
* 0.07: Long option parsing. Typo fixes by James.
* 0.08: Long option parsing now behind define.
Some systems are missing getopt_long :( This has to
solved out more general way in future.
* 0.09: pthread_init_attr, pthread_destroy_attr
were missing. Sami noticed this with Irix
* 0.10: Makefile cleanup. _GNU_SOURCE and _REENTRANT added
to tiotest.c for correct behaviour of system header files.
* 0.11: tiobench.pl by James added to distribution. Changes to
output formatting in tiotest.c.
1999-12-02 Mika Kuoppala <miku@iki.fi>
* 0.12: Sequential writing is now an option.
This prevents write phase fragmentation of test files.
Suggested by Jakob
1999-12-04 Mika Kuoppala <miku@iki.fi>
* 0.13: Tiobench.pl has now seeks as an option,
It also finds tiotest better. Few other minor fixes and
typos corrected.

* 0.14: Minor tiobench.pl cleanups
1999-12-07 Mika Kuoppala <miku@iki.fi>
* 0.15: Seeks are now truely random and unique for each thread.
2000-01-04 James Manning <jmm@users.sf.net>
* 0.16: tiobench.pl now figures default filesize by peeking
available physical ram.
2000-02-04 Mika Kuoppala <miku@iki.fi>
* 0.20: Makefile is now hopefully more portable.
Rewrote the random seeks handling totally. It can now handle
systems with 15bit RAND_MAX correctly.
Added system and user time as an measured value.
Rewrote output for both verbose and terse options.
Quick hacked tiobench.pl to accept new terse output.
Minor cleanups and fixes here and there.
Moved tiobench.sh to funnyscripts directory in order to
lessen confusion among users.
Added BUGS file into distribution.
2000-02-04 Mika Kuoppala <miku@iki.fi>
* 0.21 Few fixes in output handling.
James found out that in glibc 2.1.(x<3) rand_r is broken.
This should be fixed by how tiotest handles rand_r now.
2000-02-12 James Manning <jmm@users.sf.net>
* 0.22 - slightly modify tiotest.c output for easier parsing
- generalize perl parsing of tiotest output
- generalize output stats calculations (loop)
- calc and output CPU %
2000-02-14 James Manning <jmm@users.sf.net>
* 0.23 - added --numruns parameter for averaging runs
- update run-time prompting to include run number
- s/raleigh.ibm.com/computer.org/g for email address
- clarify rand_r issue
- corrected Mika's misspelled "misspellings" (how ironic! :)
- added header to tiobench.pl for nicer look
- comment entries in @tiotest_places
2000-02-16 Peter Palfrader <ppalfrad@cosy.sbg.ac.at>
* 0.24 - prompt to STDERR and not printing ^H s any more
- minor tiobench.pl cleanup by James
2000-03-02 James Manning <jmm@users.sf.net>

- add optional use of madvise() to control kernel paging USE_MADVISE
2000-03-14 James Manning <jmm@users.sf.net>
* 0.26 - removed funnyscripts/ that were no longer functional
- renamed funnyscripts/ to scripts/
- scripts/makeimage.pl for automated gnuplot of read rate vs. threads
- rewrite scripts/README for update
- added Gregory Leblanc's Makefile "install and "uninstall" targets
- s/-f/-d/ in targets for dir instead of file check
2000-03-16 Mika Kuoppala <miku@iki.fi>
* 0.27 - preliminary large file support
- threads compete on system wide basis now on Solaris
- scripts/bigbench.pl submitted by
Christian Robottom Reis <kiko@radiumsystems.com.br>
- minor change in random number generation
2000-03-20 Mika Kuoppala <miku@iki.fi>
* 0.28 - some tiotest.c code cleanup

- add working --help to tiobench.pl
- remove useless --raw option from tiobench.pl
- go back to previous $prompt during tiotest runs
- add --nofrag option to pass -W to tiotest
- tiobench parsing and output change for random {read,write}
- s/finnish/finish/g in tiotest.c
- change tiotest.c output printing for random {read,write}
2000-03-29 Mika Kuoppala <miku@iki.fi>
* 0.3.0 - consistency checking option for test data files
2000-05-14 Mika Kuoppala <miku@iki.fi>
