OmniThreadLibrary 3.07.2

This is just a small update which adds few helpful methods. Although the change log mentions a potentially breaking change I don't think this will affect anybody. (And if you are not sure, you can enabled backward-compatible behaviour by adding one line to the code.)

I have also (finally) found some time to work on The book. It is now fully up to date (all OmniThreadLibrary features are documented on its whooping 293 pages) and is only missing one or two introductory chapters.

As usual, you can get OmniThreadLibrary from GitHub (3.07.2, HEAD), download the zip, install it with GetIt or with Delphinus.

Change log follows after the break.

RAD Studio 10.2 links

This post contains just a bunch of links to online resources that I mentioned on the today’s presentation.

10.2 Tokyo comes to Slovenia

In two days I’ll present RAD Studio 10.2 Tokyo in Ljubljana.

OmniThreadLibrary 3.07.1

This update brings only few small changes. The biggest of them is support for the Delphi 10.2 Tokyo.

You can get it as a zipped download, git checkout, via Delphinus, and via GetIt.

Forward record declaration

Forward declaration is not really a new concept. It was already present in the original Wirth Pascal where it allowed the programmer to do one thing and one thing only – call procedure A from procedure B and procedure B from procedure A. Remember – in ye olde times of good old Pascal we had no interfaces, no classes, no units … just procedures and functions.

Because the code tells more than thousand words, here’s an example (still perfectly valid in modern Object Pascal).

procedure ProcA; forward;

procedure ProcB;
begin
  ProcA;
end;

procedure ProcA;
begin
  ProcB;
end;

OmniThreadLibrary 3.07

New year, new release ;) You can get it as a zipped download, git checkout, via Delphinus, and via GetIt.

OmniThreadLibrary 3.07 beta + plans for OmniThreadLibrary 4.0

It is almost time for a new release! If you’d like to see what 3.07 will contain – or if you just want to test it before it is out – click here.

[If you are a serious OTL user - and especially if you are using pre-Seattle Delphi - please test your program(s) with the beta release. Thanks!]

I have started work on OTL 4.0 which will (fingers crossed) fully support cross-platorm work. Yup, it will work on all platforms that Delphi can compile for! Multiplatform support was implemented by Sean B. Durkin so if OTL/Mobile is something you were waiting for a long time, go to OmniThreadLibrary-For-Mobile Google+ community and express your gratitude.

RAD Studio and Version Control + Git – links

This post contains just a bunch of links that I refered to in my two-part (live) presentation on version control management with RAD Studio and Git.

Slides for the presentation: pps, pdf

Embarcadero Akademija: RAD Studio and Version Control

This is an announcement for the next Slovenian “Embarcadero Academy” session. As it is intended for Slovenian Delphi programmers, the rest of this post is in the Slovenian language.

Debug Faster. Debug Smarter.

My CodeRage XI session on debugging in RAD Studio is now available on YouTube.

If you have missed the presentation or want to see it again, now is a good time :)

Additional materials (slides, code) are available on the Presentations page.

Hear me speak at CodeRage XI

This year I’ll be presenting two sessions at CodeRage XI.

On Wednesday, I’ll be exploring the topic of debugging in RAD Studio. I’ll show how advanced options in breakpoint properties work and drop some debugging tips & tricks here and there. Join me in room 1 at 7 am PST / 10 am EST / 16.00 CET.

On Thursday I’ll be demoing new enhancements in FastMM. If you are writing multithreaded code, then this session will be targeted to you! Join me in room 1 at 10 am PST / 1 pm EST / 19.00 CET.

Recording Webinars (repost)

As I’m pretty sure many Delphi programmers will be working on their CodeRage XI videos this weekend ;) , I decided to repost a link to my year old post Recording Webinars – My Workflow. Maybe it will be of some use to you.

OmniThreadLibrary 3.06.2

Another week, another critical update …

There was a logical error – also known as “my own stupidity” – built into OTL 3.06 which prevented programs that used OtlCommon to be started on Windows XP. This is now fixed.

There’s also a tiny addition to OtlSync included in this release.

download / git

OmniThreadLibrary 3.06.1

There was a nasty bug in DSiWin32 unit included with the 3.06 release so I had no other option than to quickly issue a fix. If you have downloaded version 3.06 then please update to 3.06.1 as with 3.06 you could experience weird crashes during program startup. I’m really sorry for that :(

There’s also a tiny addition to TOmniValue included in this release.

OmniThreadLibrary 3.06

Hi, guys! After a looong time, a new version of OmniThreadLibrary was released! It is available as a zipped download, git checkout, via Delphinus and (really soon) via GetIt.

Following stuff was added/changed/fixed since the 3.05 release:

ITDevCon 2016

ITDevCon was - as always before - a blast! Great topics, great presenters, great organization and great food!

My presentations (slides and code) are now online at the usual place.

OmniThreadLibrary Everywhere

For the last year and some, Sean B. Durkin has been working on the mobile port of the OmniThreadLibrary. There was lots to be done, as OTL was never designed to be a portable library – after all, it was created in Delphi 2007 times.

Recently I merged his latest commits into the mobile OmniThreadLibrary branch. This version is (by his words) functionally complete (although it may be missing some very recent OTL features) but is very much untested. So Sean is asking everybody that is interested in multithreading on OS/X, iOS, and Android to help him find bugs and to make OTL even more awesome!

Please report any findings to his OmniThreadLibrary-For-Mobile-DevelopmentProject on Google+. I am currently working on other aspects of the OTL and didn’t I put much energy into checking his work.

When 64 cores are not enough

Just a little teaser …

Following two branches just sprung to life:

https://github.com/gabr42/FastMM4-MP/tree/numa

Plus I started planning OTL&FastMM changes:

OmniXML Official Repository

In case you are wondering which of the many github (and even bitbucket) omnixml repos is the official one (as www.omnixml.com is still pointing to the old googlecode storage), this is it: https://github.com/mremec/omnixml.

www.omnixml.com should be pointing to the correct repository “real soon now” ;)
