[DUG] Delphi 10.2 Tokyo ready for production?

[Tony Blomfield]

I have been using 10.2 Tokyo now for 6 months or so.

The big shock was No BDE. I never realized how pervasive BDE actually was. I haven’t used any BDE components or 20 years, but never the less all of my existing projects would not compile.

I had to make a decision, and in the end installed the optional BDE that comes with Tokyo. The main driver for that was that my last version (XE2) was such a pile of crap that I couldn’t live with it any more.

The next challenge was my 3 X OEM component sets. The cost of upgrading these is a huge disincentive, and you have to think about this carefully.

If I put those two matters aside, the upgrade from XE2 to Tokyo was uneventful.

Really the main thing I have against Delphi, is the TCO. For me it’s about 4K NZD to upgrade including the 4 subscriptions. However, for building vertical applications it’s still a country mile ahead of the rest if you use it the way it is intended to be used.

I have to agree. I have to make a very considered decision to  upgrade because of the pain of having to install components. I think EMB. have come some way to help by introducing GetIt, but no all my component Devs are using it and there there are the ones who are no longer around so I have to do it myself, and the same for my own components.
I look forward to having a  "Personal" GetIt where we can specify the components we want to install therefore making Delphi upgrades easier.

For the project I'm currently working on migrating it (to 10.2 Tokyo)
should not pose too much trouble.

Indeed.

What prompted me to write this email is that while debugging for days I
got the feeling I was working with a substandard product (XE5 +
FireMonkey). Multithreading is a basic necessity in any responsive GUI
application these days. And even if one would not create their own
threads, threads are created by the RTL in many occasions. I wasn't too
pleased finding out that - apparently - XE5 FireMonkey RTL wasn't tested
well enough. I have the hope that things are much better in 10.2 Tokyo
but then I've been bitten by that sort of thinking before.

If by upgrading I would get a well tested production ready development
platform for Windows, MacOS, iOS, Android and Linux, I'd be tempted to
once more spend the money.

There is, but as far as I can tell only in the Enterprise or Architect
editions (https://www.code-partners.com/product/delphi)

It sure does, many thanks!
