Why I always disable Castalia in Delphi

Posted by jpluimers on 2016/11/18

I wrote about disabling Castalia before. This is yet another reason why I disabled it: on a fresh install it will throw errors at startup like this one in XE8: [WayBack] http://qc.embarcadero.com/wc/qcmain.aspx?d=139278

Oh nice: the compiler settings in your .dproj files are not reflected in what Ctrl-O O emits in XE7

Posted by jpluimers on 2016/11/15

I need to test this with other Delphi versions:

Oh nice: the compiler settings in your .dproj files are not reflected in what Ctrl-O O emits as it always puts this as first line in your source code for Delphi XE7:

{$A8,B-,C+,D+,E-,F-,G+,H+,I+,J-,K-,L+,M-,N-,O+,P+,Q-,R-,S-,T-,U-,V+,W-,X+,Y+,Z1}

Which means that changing integer values in <DCC_Alighment> or <DCC_MinimumEnumSize> and boolean values in <DCC_Optimize> have no effect.

Bummer.

Source: Oh nice: the compiler settings in your .dproj files are not reflected in what…

I will officially report it as soon as https://www.ssllabs.com/ssltest/analyze.html?d=quality.embarcadero.com grades B or better.

And I need to find out if I can help determining which of these causes it via [WayBack] Thomas Mueller (dummzeuch) – Google+:

There are two possibilities:
1. The settings in the dproj file have no effect
2. The settings Ctrl-O O writes to the source file do not reflect the actual compiler settings but are hard coded instead.
(3. Both)

One of the #EKON20 running gags: Raize condition

Posted by jpluimers on 2016/11/11

When Ray Konopka enters the room you have a Raize condition.

Via the EKON20 sessions, it made its way into the workshop If you thought you could do multi-threading, then play “The Deadlock Empire” games – Entwickler Konferenz

Fixing `Unable to create ModelMaker Tools Shared Directory` and `Cannot create file “C:\HungarianTypeLookup.txt”. Access is denied.`

Posted by jpluimers on 2016/11/10

Like many Delphi 3rd party product, new ModelMaker Code Explorer (often abbreviated as MMX) releases have not been as thick as in the heydays (look at the history for versions 7, 8 , 9, 10, 11 and 12).

Unlike a lot of products it is still there, still very stable and hasn’t been acquired which it means it is available for a wide range of Delphi versions. So I still use it, but know certain issues will likely be never solved.

One of these issues is running ModelMaker Code Explorer as a different user than the installing user. In the authors words:

You need to install MMX as the same user that will run MMX.
MMX does not support running as a different user than the one installed.

This requirement becomes increasingly difficult to satisfy. This especially happens in more security conscious organisations where there is a clear distinction in rights between users that can install software and the ones that use the software. But it can also happen when you switch users because of infrastructure changes (new Windows domain, no Windows domain, etc).

Delphi itself copes reasonably well with that, as does GExperts, but MMX doesn’t. Despite the writeup on How to verify a Code Explorer installation? it lacks two things:

  1. explaining the below kinds of error messages when you run MMX with a different user than you installed MMX
  2. explaining some easy steps to fix this

As I roam a lot, I’ve spent about a day fiddling and writing up the below information:

Old Google Charting API: tools for still using them

Posted by jpluimers on 2016/11/10

While mocking the ScaleMM documentation, I bumped into a chart that I thought was an image, but is in fact generated by the (now deprecated) Image Charts API from Google.

In fact it is generated on the fly from a URL: http://chart.apis.google.com/chart?chxr=0,0,16|1,0,14682…&nonsense=something_that_ends_with.png

Compare the two below. They are identical (:

Static ScaleMM1 comparison chart

Static ScaleMM1 comparison chart

URL based ScaleMM1 comparison chart

URL based ScaleMM1 comparison chart

Even though the API is deprecated Google has no plans to turn it of, so it still works and is the easiest way to get charts into a Markdown or reStructuredText document.

In practice, it doesn’t matter if you use the chart.apis.google.com or chart.googleapis.com domain: they give the same results the same.

As I wanted to convert the results.txt to a chart, I dissected the above URL, looked up the definitions of the URL parameters (the trickiest: cds for lxy graphs and the combination of chds and chxr, easier: chls) and created a new URL for the chart below.

Locking Is there a good open source MREW lock object out there that – Supports…

Posted by jpluimers on 2016/11/09

Summary of the  Locking Is there a good open source MREW lock object out there thread:

Don’t use MREW. Too many bugs in any implementation, and too easy to make deadlocks.

Use other locking mechanisms that are lighter, easier to understand and therefor less prone to mistakes.

The SelectiveDebugging plug-in now supports Delphi 10.1 Berlin.

Posted by jpluimers on 2016/11/08

This post is a reminder to myself that this plugin exists at all.

Hopefully by this time it supports more recent Delphi versions as well; when scheduling this post, it supported from XE to 10.1:

My SelectiveDebugging plug-in now supports Delphi 10.1 Berlin. The updated download can be found at the end of the corresponding blog post:… – Uwe Raabe – Google+ [WayBack]

Delphi Continuous Integration: When you get E2202 “Required package ‘rtl’ not found” or F1027 “Unit not found: ‘System.pas'”

Posted by jpluimers on 2016/11/08

If when setting up Continuous Integration (CI) with Delphi and you get errors like E2202 "Required package 'rtl' not found" or F1027 "Unit not found: 'System.pas'", then something is wrong with your library path on the CI server.

Before going into the details of why, the quick solution is to set either of these environment variables in your build script

  • Delphi 2007, 2010: Win32LibraryPath
  • Delphi XE and up: DelphiLibraryPath

Now back to the details of why these might not be set, most information is from my Delphi build automation workshop.
