This release makes over 150 improvements to the current Enterprise TWiki.

Along with many WYSIWYG Editing improvements, better UTF8 support, User mapping fixes and SEARCH improvements, This release contains an optimization that should see 4.2.1 being 10-30% faster than 4.2.0.

I will be updating the TWikiInstallers as soon as I can - the Windows installer should see the biggest impact, as I have managed to fix a number of SEARCH issues that are windows specific.

see TWikiRelease04×02x01 for more details.

I’ve just updated the Experimental TWiki and Plugins repository. It now contains TWiki 4.2.0 and 212 Plugins, Contribs and Skins that you can simply apt-get install

To use them, add the following 2 lines to your /etc/apt/sources.list

deb http://distributedinformation.com/experimental/ experimental main contrib
deb-src http://distributedinformation.com/experimental/ experimental main contrib


then type

apt-get update

to update the available packages.

you can now see all 212 packages with apt-cache search twiki-

and install (assuming you don’t have twiki installed yet)

apt-get install apache2 twiki

and TWiki Contrib installation is as easy as

apt-get install twiki-bugscontrib

You will still need to use configure to enable Plugins.

Please report your experiences to me - bugs, gripes, you name it - its a work in progress. and I need your help!

I’ve been using firefox 3 on my notebook since beta3, and loving its lower CPU and memory needs, but have been frustrated by the lack of 64 bit builds for my 8Gig RAM desktop development and VMWare system.

It seems that they have been building 64bit binaries for quite some time - see their nightly build dir.. http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/

NICE!

Another TWiki innovation brought to you by distributedINFORMATION & WikiRing.com

I’ve been promising myself some time to try out DTrace on TWiki’s codebase for over a year. By following Bryan Allen’s
instructions using Richard Dawe’s adaption of Alan Burlison’s work… I now have a Perl 5.8.8 with DTrace probes.

Sounds great, except for one thing…. I now have to learn enough about DTrace to use it The patch that Alan and Richard have (or at least their DTrace scripts) seem to require a priori knowledge of the Perl process’ pid… not something thats going to work out for what I want to do.

For a quick test, DTrace -c ./view -s /export/home/sven/src/dtrace/subs-tree.d does show the program flow.

The following is while running some perl scripts - the 2 numbers are their pids.

# dtrace -l | grep -i perl

17803  perl17669        libperl.so                      Perl_pp_sort sub-entry

17804  perl17669        libperl.so                   Perl_pp_dbstate sub-entry

17805  perl17669        libperl.so                  Perl_pp_entersub sub-entry

17806  perl17669        libperl.so                      Perl_pp_last sub-return

17807  perl17669        libperl.so                    Perl_pp_return sub-return

17808  perl17669        libperl.so                     Perl_dounwind sub-return

17809  perl17669        libperl.so                Perl_pp_leavesublv sub-return

17810  perl17669        libperl.so                  Perl_pp_leavesub sub-return

88501  perl17760        libperl.so                      Perl_pp_sort sub-entry

88502  perl17760        libperl.so                   Perl_pp_dbstate sub-entry

88503  perl17760        libperl.so                  Perl_pp_entersub sub-entry

88504  perl17760        libperl.so                      Perl_pp_last sub-return

88505  perl17760        libperl.so                    Perl_pp_return sub-return

88506  perl17760        libperl.so                     Perl_dounwind sub-return

88507  perl17760        libperl.so                Perl_pp_leavesublv sub-return

88508  perl17760        libperl.so                  Perl_pp_leavesub sub-return

so… first ignorant modification - in subs-tree.d, it wants to trace perl$target:::sub-entry - change that to perl*:::sub-entry, and of course, it works exactly as I want - attaches to all subsequent perl process (running my dtrace-perl build) and tells me whats going on. The only caveat being that the DTrace script will only start if there is a Perl process running - the provider is obviously not persistent.

Brilliant!

Should be a fun Christmas holiday adventure - 410 pages of dtrace book, and a myriad of web pages to consume and digest.
