the release of 1.2 is almost there! We are working hard to deliver it shortly after the next Delphi release which will happen … soonish, I think. ;)
The release/1.2 branch has been around for a while – please take a look if you haven’t already. It contains a lot of new features and bugfixes. I will tell you more about some of the amazing features next time which won’t take as long as it took since the last blog post – promise. :)
Apart from a very interesting take on DI resolvers, the above great info too!
Please take a look at spring4d/branch/release/1.2 as it has been very stable for quite some time.

Some links that were useful getting back into using Delphi with resource scripts and include files:
Maybe I should have considered this alternative:

… there’s no need to use WaitForMultipleObjects in Step 2. It’s fairly easy to keep a counter of active threads in the pool (interlocked-incremented when a thread starts, interlocked-decremented when a thread is finished). When the counter reaches zero (no more active threads), signal an event. With only one event to wait for, you can use WaitForSingleObject…
So no more 64-thread (MAXIMUM_WAIT_OBJECTS) limits for pools…

Does anyone have a run-time fix for
CreateInOutError raising an
EInOutError with
Code=
3 (correct) and
Message=
'Invalid file name - %s' (incorrect because
System.SysUtils should have used
System.SysConst not
System.RTLConst and
System.RTLConst wrongly duplicates some resource strings in
System.SysConst) See [

http://qc.embarcadero.com/wc/qcmain.aspx?d=129530.
It would be so cool if a fix fills in the %s with the invalid file name.

Almost 2 decades after the first Delphi Linux support in [WayBack] Borland Kylix by an full tool-chain (IDE, compiler, debugger, libraries) running on Linux, Embarcadero/Idera is about to support Linux again in a cross-compiler fashion that was originally scheduled for late 2016 as Delphi Godzilla [WayBack] Embarcadero RAD Studio 2016 Product Approach and Roadmap – Embarcadero Community and [WayBack] Linux support for Delphi to be available end of 2016 – Synopse.
It seems to be finally getting here as Delphi 10.2 Tokyo when you look at the [Archive.is] Delphi Linux Boot Camp promotion for instance at [WayBack] Delphi Linux Boot Camp – Community Blogs – Embarcadero Community.
I’m curious at what people expect from it.
So please comment your expectations, for instance:
- what Linux distribution targets
- what processor architectures
- what language support (ARC, classic, 1-based strings, etc)
- what library support
- what IDE support (like debugger features)
- what speeds
If you want to get a head start, then read these:

A long time ago, Thomas Mueller (dummzeuch) – Google+ reminded [WayBack] me of this which I required a short while ago:
You can use AcquireExceptionObject():
AcquireExceptionObject returns a pointer to the current exception object and prevents the exception object from being deallocated when the current exception handler exits.
Then you can send the pointer to another thread and if you raise it there it will be freed for you, otherwise you must call ReleaseExceptionObject() to free it.
After the answer by Remy Lebeau [WayBack] and Remko [WayBack] is a comment [WayBack] by [WayBack] that mentions AsyncCalls.pas that now is available on GitHub [WayBack].
If you have a very old (version <= 5) Delphi or just want to look at how AcquireExceptionObject [WayBack] looks like just look at a similar implementation there [WayBack]. Note that instead of the ReleaseExceptionObject [WayBack] call, AsyncCalls re-raises the exception [WayBack].
