Rule 1: try to find at least something postive.

From a while back, but still interesting especially because there some differences similar to base/inherited designer objects: [WayBack] vcl – How to do bulk -transformation of form to frame- in Delphi? – Stack Overflow:
Observe the differences of a Form and a Frame in your project.
First the project.dpr source:
program Project1; uses Forms, Unit1 in 'Unit1.pas' {Form1}, Unit3 in 'Unit3.pas' {Frame3: TFrame}; {$R *.res} begin Application.Initialize; Application.MainFormOnTaskbar := True; Application.CreateForm(TForm1, Form1); Application.Run; end.Differences:
- Frame as a more elaborated comment to tell the IDE which designer it should use
- Form can be autocreate
Dfm files:
object Form1: TForm1 Left = 0 Top = 0 Caption = 'Form1' ClientHeight = 348 ClientWidth = 643 Color = clBtnFace Font.Charset = DEFAULT_CHARSET Font.Color = clWindowText Font.Height = -11 Font.Name = 'Tahoma' Font.Style = [] OldCreateOrder = False PixelsPerInch = 96 TextHeight = 13 endand
object Frame3: TFrame3 Left = 0 Top = 0 Width = 320 Height = 240 TabOrder = 0 endFrame does not have these properties:
- Caption
- ClientHeight
- ClientWidth
- Color
- Font.Charset
- Font.Color
- Font.Height
- Font.Name
- Font.Style
- OldCreateOrder
- PixelsPerInch
- TextHeight
Sidenote: Frame does not have these events:
- OnCreate
- OnDestroy
A Frame has not global variable like this:
var Form1: TForm1;And a Frame descends from
TFrame, whereas a form descends fromTForm.Note: with Frame/Form inheritence, your steps become a bit longer.

Some of these are similar to the differences you see here:

PS: Idea: make a wizard or conversion tool for this.

If you want to restrict the WSDL publishing so it only is published in DEBUG mode, then add a [WayBack] TWSDLHTMLPublish to your [WayBack] TWebModule descendant, then add this in the [WayBack] OnCreate event handler of that TWebModule descendant:
// Enable/disable handling of "/wsdl*" requests during DEBUG/RELEASE mode. Enabling sends them via
// Handled := WSDLHTMLPublish1.DispatchRequest(Sender, Request, Response);
{$ifdef DEBUG}
WSDLHTMLPublish1.WebDispatch.Enabled := True;
{$endif DEBUG}
{$ifdef RELEASE}
WSDLHTMLPublish1.WebDispatch.Enabled := False;
{$endif DEBUG}
end;
I have limited this because there are so many hard coded strings in the TWSDLHTMLPublish, see the thread by [WayBack] Marjan Venema at [WayBack] Hide WSDL document in SOAP app – delphi

I found out this is a problem until at least Delphi 10.1 Berlin, but my original question was for XE8:
Is there any tool that clears the Delphi memory overhead when a “build all” switches to the next project in a project group?
XE8 constantly runs out of memory with large project groups as the memory usage keeps increasing for each project it builds in the group.
There are actually two answers:
Uwe Raabe: Have you tried with Use MSBuild checked for each project?
Jeroen Wiert Pluimers: +Uwe Raabe Much better. Much slower too (:
and:
Torbjörn Olsson: Have you tried DDevExtensions?There is a setting named “Release compiler unit cache before compiling”
I’ve opted for the [Archive.is] DDevExtensions; I thought this VM had it installed, but apparently I forgot installing it as [Archive.is] IDE FixPack by the same author was installed.
This is how you configure DDevExtensions:
- Run Delphi
- Choose menu “Tools”, submenu “DDevExtensions Options…”
- In the dialog, select “Compilation” in the list on the left
- Ensure “Release compiler unit cache of other projects before compiling” is checked
- Confirm any changes

In the comparison below:
With “Use MSBuild externally to compile”
Regular “Build all”

An automated build system for your Delphi applications is gold, and straightforward to setup using the Delphi support for msbuild.
Sometimes however, it is convenient to build any or all Configuration/Target permutations of all your projects from inside the Delphi IDE.
This has been possible since Delphi XE introduced the [Archive.is] Build Groups – RAD Studio XE. It is a really nifty feature which you can activate by clicking on the “people” icon in the project manager: 
.
Uwe Raabe has witten an excellent blog post on this a few years ago: [WayBack] Do you know Build Groups? | The Art of Delphi Programming
Since you can add multiple Build Groups, you can select which one contains what Configuration/Target permutations of any number of projects.
This for instance allows you to:
The Build Groups settings are saved as part of your groupproj settings and are a pretty stable feature.
Two extra tips:

Over the years, various Delphi versions have cluttered the Project Options hierarchy quite a bit. This means that when you walk this hierarchy in the Project Options dialog, you will see many bold entries, indicating they have been changed for that level in the hierarchy.
The most important tip is to keep as much as possible at the top level, preferably using relative paths or paths containing $(...) macros.
I usually fill these entries there:
.\$(Platform)\$(Config).\$(Platform) when you nave libraries containing DCU files per platform
$(Platform)\$(Config) here if these DCU files are different for configurations (DEBUG/RELEASE) as well..\$(SanitizedProjectName)\$(Platform)\$(Config) or .\$(Platform)\$(Config)\$(SanitizedProjectName) in the path)DEBUGRELEASEI include the $(SanitizedProjectName) because it has the name of your project, which I documented at Source: Delphi XE8 does not adhere the $(PROJECTNAME) in a “Unit Output Directory”, but does recognise $(SanitizedProjectName) including many other macros.
Note:
$(Platform) in the Tools -> Options -> Library Path setting, as at least Delphi XE4 can remove it while checking for invalid paths; see[WayBack] Delphi XE4 LIbrary Path – Delete Invalid Paths deletes critical data! – embarcadero.delphi.ideOutputDirectory with $(SanitizedProjectName) cause the debugger not to find your executable:A long time ago, +Uwe Raabe explained that you can use $(SanitizedProjectName) in your project settings to include the actual project name in https://plus.google.com/+DavidNottageDelphiExpert/posts/PcW8CwMQGmH
This works great for DCU output, but not so well for EXE output: when using for instance
C:\Binaries\$(SanitizedProjectName)as target, the debugger cannot find the executable as the compiler puts it in the wrong place.Example with a fresh console project:
0. Ensure
C:\Binariesexists and you have write access to it
1. Set Output directory toC:\Binaries\$(SanitizedProjectName)
2. Set Unit output directory to.\$(SanitizedProjectName)\$(Platform)\$(Config)
3. Run:--------------------------- Error --------------------------- Could not find program, 'C:\Binaries\%SanitizedProjectName%\Project1.exe'. --------------------------- OK ---------------------------The executable is actually at
C:\Binaries\Project1.exe, so the compiler does not take the “\$(SanitizedProjectName)” bit into account.Anyone with a fix for that?
Via [WayBack] A long time ago, +Uwe Raabe explained that you can use $(SanitizedProjectName) in your project settings to include the actual project name in https://pl… – Jeroen Wiert Pluimers – Google+
To make the compiler use the correct path the SanitizedProjectName item must be located before its use in the dproj file. DprojNormalizer assures that since version 2.2.1 and ProjectMagician does so, too. Thus my Project1.exe is written correctly toC:\Binaries\Project1\Project1.exehere on my system.
Unfortunately that won’t fix the main problem, which is that the call to the debugger doesn’t resolve this variable in the first place. Currently I don’t know how this could be fixed.
It looks like the .dproj is this using itself too, for instance as this part:
<Import Project="$(MSBuildProjectName).deployproj" Condition="Exists('$(MSBuildProjectName).deployproj')"/>

[WayBack] A compiler curiosity I’ve learned today … – David Berneda – Google+: depending on if TEST is defined or not, you get E1026 or W1023.
// This works:
{$IF Declared(Test) and (Test>=100)}
{$ENDIF}
// This not:
{$IF Declared(Test)}
{$IF Test>=100} // "E2026 Constant expression expected"
{$ENDIF}
{$ENDIF}
The W1023 can be alleviated by replacing 100 with +100.
Note that both errors have been documented since at least Delphi 2007:

Cool set of steps on [WayBack] How I use Wireshark – Julia Evans who uses the combination of tcpdump to dump traffic in pcap files and Wireshark to analyse the pcap files after copying them using scp. On many platforms, Wireshark can also capture the ptrace files for you.
Via: [WayBack] 🔎Julia Evans🔍 on Twitter: “how I use Wireshark https://t.co/j699JXrjaH” which has some nice comments including:
ptrace to your tool-kitscp for copying, as you can do [WayBack] dumpcap over an existing ssh connection:
wireshark -k -i <(ssh <IP> "sudo dumpcap -P -w - -f 'not tcp port 22'")–jeroen

An interesting discussion sprouted from the bragging [WayBack] Did you know the IDE starts almost twice as fast in 10.2.2 as it did in 10.1? https://community.embarcadero.com/blogs/entry/new-in-10-2-2-welcome-page-… – David Millington – Google+.
I do not care very much about IDE start times (Visual Studio starts faster, others like Android Studio start slower than Delphi), more about productivity.
Which means loading projects, opening files and forms, switching projects, etcetera need to be fast and stable.
For me this is when on Delphi projects, I start about half a dozen copies of Delphi about 10 seconds apart (otherwise you get exceptions in any Galileo version), make some tea, then come back.
Each time an IDE crashes, I kill it, start a new one, switch to an existing one, load the projects I need and continue. On a full day working with Delphi, this happens about a dozen times a day.
After that I want to be productive.
Here is where I was so surprised by the great tip from Yusuf Zorlu
+Asbjørn Heid you should try to disable all “livebinding” packages + rename dclbindcomp250.bpl . If i opened a form before i had to wait 20 to 40 seconds … now it is superfast and opens forms under 5 seconds. I don’t need LiveBindings …
and the response by Asbjørn Heid
+Yusuf Zorlu Thank you! Holy cow that’s a difference! As you say, even our most complex forms are down to 4 seconds now.
I never use LiveBindings as they are way to convoluted, unstable and result in logic being in designers as opposed to tool-manageable code.
In addition, LiveBindings have never been really optimised since their inception in Delphi XE2.
This saves a lot of time!
So one day, I need to update Source: Delphi packages I have disabled by prefixing their description with an underscore (and why) and create a batch file with the various [WayBack] reg add commands modifying the package loads.

Delphi formatter setting, so I can manually arrange uses lists:
–jeroen
Also available in MMX Code Explorer in the settings dialog: Pascal -Sorting – Format unit uses clauses – “Each unit on a new line”.
If you prefer the standard setting and spare the other for special purpose, there is “Format Uses – Alternate” in the context menu. Perhaps give it a decent shortcut for quick access.
Bernd Ott in the same thread:
Important because scm. Less merge trouble. Only the last semicolon in last row is always stupid.
