Reminder to self – Fiddler for OS X Beta

Posted by jpluimers on 2018/01/11

Reminder to self: [WayBack] Fiddler for OS X Beta as it’s been on my list since about a year ago: Fiddler for OS X Beta « The Wiert Corner – irregular stream of stuff.

Note that reading the cerficicates can be done in a more simple way for the Current version of Mono:

/Library/Frameworks/Mono.framework/Versions/Current/bin/mozroots --import --sync

I forgot in which version the Mono installer has Current linked to the most recently installed Mono version but it works well.

Executing should then be somethig like this:

/Library/Frameworks/Mono.framework/Versions/Current/bin/mono ~/bin/fiddler-mac/Fiddler.exe

I expect quite some bit of trouble decrypting HTTPS [Arvhive.is] as that was troublesome on Windows in the early Fiddler days as well.

In case of trouble, there is always Fiddler Ideas: Customer Feedback for Fiddler by Telerik . Add a new product idea or vote on an existing idea using the Fiddler by Telerik customer feedback form via [WayBack] Tsviatko Yovtchev: “@jpluimers @ericlaw https://t.co/lRNXC88M1b is our feature suggestion/issue tracker portal. Fiddler itself notifies on new versions.”

Back to the reminder: [WayBack] Fiddler for OS X Beta.

Direct download https://telerik-fiddler.s3.amazonaws.com/fiddler/fiddler-mac.zip.

Downloading Fiddler for OS X Beta…

If your download does not start, please [WayBack] click here to retry

Getting started

  1. If you don’t have the Mono framework installed on your Mac

    Please download it from [WayBack] http://www.mono-project.com/download/#download-mac and install it. If you already have it installed, ensure you’re running the latest version.

  2. If you just installed Mono

    Please open Terminal and type in:

    /Library/Frameworks/Mono.framework/Versions/<Mono Version>/bin/mozroots --import --sync

    (The Mono framework has its own trusted root certificates store. Currently (at mono version 4.2.4) this store remains empty after installing Mono on OS X. Fiddler uses the certificates in this store to validate the certificates of the websites visited. So you need to populate this store with a set of commonly trusted root authorities to avoid getting constant certificate warnings from Fiddler. The mozroots tool imports trusted authorities from the Mozilla LXR. )

  3. Extract fiddler-mac.zip to a folder you have write access to.

    It is recommended that the full path to Fiddler install folder does not contain any Windows path illegal characters. (At present it is possible that some Fiddler functionality, e.g. various file exports or Fiddler Script won’t handle such paths.)

  4. Open Terminal and navigate to the folder you extracted to in step 3.

  5. Type mono Fiddler.exe in Terminal.

To further understand the benefits and limitations of Fiddler for OS X please visit [WayBack] this blog post.

xs:choice element to C# – Google Search

Posted by jpluimers on 2018/01/10

Some links via xs:choice element to C# – Google Search.

I need them one day to better understand xsd:choice mapping to C# for both XSD and WSDL usage.

I have the feeling that the WSDL and XSD importer are trying to be smart, so for instance when you have multiple choices that come down to a common basic type like a derivation from xsd:string, it makes to two properties: a C# enumeration to select the type and a C# string value for the content referencing the enumeration through a XmlChoiceIdentifierAttribute.

Delphi: playing Chimes.wav as an external file or embedded WAVE resource in Delphi XE5.

Posted by jpluimers on 2018/01/10

As a by-effect, this article seems to one of the few that shows where Delphi uses the .dres file extension introduced around Delphi XE.

Recently I had to play some notification sounds in a Windows Delphi application where the application deployment should be as easy as possible: preferable copying the EXE around.

Playing a sound file seems easy, especially if it is a [WayBack] WAV file: just use the [WayBack] PlaySound or the (older) [WayBack] sndPlaySound API functions.

But if you start searching on the internet, you see lots of curious implementations for playing WAV resources through sndPlaySound.

The actual implementation is really really easy though, just make sure you follow the steps right and nothing can go wrong.

[WayBack] The full source code is on my BeSharp.net repository, here is how to to it step by step:

The steps depend on the MMSystem unit, so most of the code translates back to [WayBack] Turbo Pascal for Windows (yes, the 16-bit Pascal days when the MMSystem unit was introduced) with the exception of the SND_SENTRY flag.

The thing that more recent Delphi versions made a lot easier is embedding WAV files as WAVE resources, more on that further on. Read the rest of this entry »

Damned ! var Comp : function(const s1, s2: string): Boolean; begin if CheckB…

Posted by jpluimers on 2018/01/10

One of my main gripes about lots of RTL/VCL/FMX code: conventions are often lacking.

Which means one of the below functions starts with Ansi (but does a Unicode operation) and the other has the parameters in reverse.

var 
  Comp: function(const s1, s2: string): Boolean;
  begin 
    if CheckBox1.Checked then 
      Comp := ContainsText 
    else 
      Comp := AnsiStartsText;
  end;

Autoregister attribute for Delphi | Jon L. Aasenden

Interesting idea:

[WayBack] Wouldn’t it be nice if Delphi has an attribute that automatically registers your class for you? – Lennart Aasenden – Google+

Anonymise of data is hard, not just for now, but especially preventing future de-anonymisation

Posted by jpluimers on 2018/01/09

Two very interesting videos showing some background information as it is extremely hard to anonymise data. Not just for now, but especially against future de-anonymisation efforts.

Some FastMM scenarios require NeverUninstall because the System unit finalizes things innitialised in other units

Posted by jpluimers on 2018/01/09

You always have to be careful  with Delphi finalization sections cleaning up things that might have not created inside the corresponding initialization section. This is especially true for the System unit.

That one actually contains this little piece of code that is being called after FinalizeUnits is called which also fianalises external memory managers like FastMM:

finalization
{$IFDEF WEAKREF}
  InstHashMap.Finalize;
{$ENDIF}...
{$IFDEF MSWINDOWS}
 FinalizeLocaleDate;
 if PreferredLanguagesOverride <> nil then
 FreeMem(PreferredLanguagesOverride);
...

Which means that you will have to enable the NeverUninstall conditional define as soon as the InstHashMap has been used.

Most often that’s the case with FMX applications that heavily relies on weak references.

The same holds for PreferredLanguagesOverride which is used by SetLocaleOverride and can be worked around by performing this right at the end of the .dpr:

SetLocaleOverride('');

How did this shit ever work? – The Isoblog.

Animation problems in Delphi Tokyo 10.2 update 2? Check bug RSP-19525

Posted by jpluimers on 2018/01/07

If you run into animation problems in Delphi Tokyo 10.2 update 2, then read [WayBack] … In particular I cannot use the use the animation to change the tab in a TabControl… – Raffaele Miola – Google+.

It is likely that  RSP-19525 (10.2 Tokyo Release 2 breaks Animation under Android – App hangs).

Some temporary fixes that might help you are here:

I think that for cross platform and especially mobile development means you need to use tools from vendors that live and breathe that, by constantly showing they master these subjects for instance having good apps in the app stores and examples that are regularly updated to the ever changing field.

I really wonder what the rest of the Delphi community thinks about that.

Record helpers can do wonders for code clarity.

Posted by jpluimers on 2018/01/04

A few people recently discovered the beauty of record helpers:

Record helpers can help any value type (which includes enumerated types) so you can add functions to enumerations.

Class helpers can help class types.

There are no interface helpers and likely won’t be there for a long while.
