Re: How to build a standalone app for Windows using Mac
James, I have 4D Developer Pro licenses for both macOS and Windows. I run my Windows 10 environment as a virtual machine on my Macbook Pro using Parallels. My primary 4D development has been done for years on a Mac as I like the macOS environment much better for many reasons. You simply copy the standalone app from the Mac to the PC and then using 4D Developer Pro, test it in the Windows environment and once bug free, re-compile it using your 4D Developer Pro for Windows license. There are minor and generally well-documented differences when running a 4D app between the two operating system environments. As an example, I ported 4D v18 app from macOS Catalina to Windows 10 three weeks ago that reads and writes directories. I thought I'd taken care of the path delimiter differences between Mac (colon) and PC (backslash), but it is currently aborting in testing when trying to read a Windows directory. It works flawlessly in macOS. It is probably a very simple fix, but fixing it right now is not at the top of my priority list.

Re: 4D v18.0 LTS - Form Wizard Missing
I was disappointed when 4D v18.1 was released and it did not include the missing Form Wizard in the Database Projects. I really want to use Projects because the code can be versioned as Ascii as normal for nearly all other code, but without the Form Wizard it is difficult. It also makes me wonder “what else” is missing. I wonder why this traditional 4D tool is missing.

Re: Generate Digest MD5 - Max Input File Size?
Wow! This thread has yielded a wealth of information about hashes & checksums and the issues surrounding generating and using them. David Adams’s Hash Tool Component PDF finally gave me a good explanation about what a Hash is and provides a good resource. I’m still a little bit foggy about the difference between what a Hash is vs. what a Checksum is. Are they really different? Since the 4D Language itself doesn’t use the concept of hashes (I know they are used in other programming languages extensively), I simply don’t know much about them. I downloaded Keisuke’s Hash plugin and will be testing it for use in my app during the next few days to generate MD5 checksums on files.

Re: Generate Digest MD5 - Max Input File Size?
The code that was failing on the 687.6 MB file with an out of memory error follows. In order to use the Generate digest command on a file, you have to convert the file to a BLOB first. If I would have written it, I would have just read in the file directly and computing the checksum as it streamed in, but for some reason the method’s author chose to allow only BLOB or Text as input.

Re: Questions about workers
I have many of the same questions you do about Workers. I only discovered the new concept of Workers three days ago and am running experiments to try to figure them out myself. But I can offer up the following. As for High Velocity: I created an iteration loop that called a Worker. The only thing that I had the Worker do was to Create a new record, store the iteration number + current date + current time in it and save the record. I set it up for 500,000 iterations. It took about the same time as just running in the same process (I didn’t exhaustively compare numbers). It doesn’t seem to have the normal time lag that would occur to start up a New Process. Anyway, it was very fast. I was also concerned about what would happen when a Worker was given a new request while it was still executing a previous request. So I lmited the integration to just 20 records, but introduced a 3 second time delay. It stored up those requests and executed all of them. It did not drop any of the request on the floor. I believe it executed the Worker requests in the same sequence of the Worker calls from my iteration loop, but I am not certain about that. I now am wondering what the limit is for the number of requests to the Worker that can be stored up? I did discover what I think is a Worker bug in doing these simple tests. Each time I ran these little tests, the very last record that was created and then saved by the Worked is edit locked. It can’t be deleted. I hope this helps at least a little bit.

I guess the stack will have the mystery "default size", but I’m not sure... ;) - I know that preemptive execution implies no interprocess variables. OK. But, if the preemptive aspect is not a priority for me now, can I still use inteprocess variables without any problem in my workers? – Is the use of workers not for a high velocity compute section of an app, but for a regular part, with basic records filling and so, reasonable or not? with the idea to call the worker-process by the "call form" command, when needed). Why would I do that? Because some of my apps have a concept of several permanent processes with reuse of those. So, the workers would be better than the processes which are most of the time sleeping, then wake up, then go back to sleep, and so on...
