Why I wish QC had been archived in full…

Posted by jpluimers on 2018/10/25

A quick search later and it seems I’m bumping into [WayBack] http://qc.embarcadero.com/wc/qcmain.aspx?d=125403 (the version I’m bugfixing is built using XE6).

The workaround listed (in my case blanking indexfieldnames in OnBeforeClose) works.

Now… imagine if this had been filed to QualityPortal instead.

I would have had to remember to search it, and maybe wouldn’t have found it as Google does fuzzy searches very well.

And due to the lower visibility it likely would have fewer comments as well…

So yeah EMB/Idera, please revisit the choice of walling up QualityPortal.

Delphi: uninstalling the ancient CollabNet 1.7.5 version

Posted by jpluimers on 2018/10/24

Somehow the integration team at Embarcadero still hasn’t discovered there are [WayBack] newer CollabNet SVN Client versions than 1.7.5 which has been shipped since Delphi XE3 until Delphi XE6. The newer version (currently 1.8.8 when writing this, now 1.10.2 in 2018) have plenty [WayBack1/WayBack2SVN security issues fixed.

The easiest way to uninstall the CollabNet SVN Client is running this small script:

Then install the [WayBackSlik SVN client. Like [WayBackЈοеу, I’ve switched to [WayBackSlik SVN a long ago. Here is [WayBackhis reasoning:

I have long since stopped using the CollabNet-branded version because it’s behind a registration wall. I found Slik SVN as a good alternative. It’s exactly the same command-line client you get from CollabNet, sans the hassle in downloading it.

I hope someone at Embarcadero enters this in QC^w QualityPortal as I’m awaiting Embarcadero response about a security issue there.

I totally forgot that Delphi has had a function to get the current executing thread – Stack Overflow

Posted by jpluimers on 2018/07/05

While updating some old code fiddling with the[WayBackGetThreadId function, I wanted to have some TThread wrapper around it. I had totally forgotten there has been already a means for this since Delphi 2009 (which initially had a bug, but that was worked around at first and fixed later): [WayBackCurrentThread.

The latest version of Delphi, Delphi 2009, has a CurrentThread class property on the TThread class.

This will return the proper Delphi thread object if it’s a native thread. If the thread is an “alien” thread, i.e. created using some other mechanism or on a callback from a third party thread, then it will create a wrapper thread around the thread handle.

Delphi still doesn’t raise overflow exception on Int64 multiplication…

Posted by jpluimers on 2018/06/28

Thanks to Stefan Glienke for pointing me at the below patch for [WayBack] Why doesn’t raise overflow exception on multiplication example or how to detect in this case?{$RANGECHECKS ON} {$OVERFLOWCHECKS ON}varvalue: Int64;… – Rafael Dipold – Google+.

It’s basically an issue in __llmulo that has been documented but not solved since “forever”:

some people “some while ago” reported this and even posted a solution: [WayBackhttp://qc.embarcadero.com/wc/qcmain.aspx?d=34049

And there it is again: [WayBackhttp://qc.embarcadero.com/wc/qcmain.aspx?d=119146

And most recently: https://quality.embarcadero.com/browse/RSP-16617

FWIW here is a runtime patch that corrects this (using the version posted in QC#119146): https://pastebin.com/jzLgYeqm

The bug tracking of the Delphi team is so bad, that some of the reports actually mark this issue “As Designed” like in [WayBackhttp://qc.embarcadero.com/wc/qcmain.aspx?d=118287

The below patch requires rights to call [WayBackWriteProcessMemory as documented in [WayBackHow to Read and Write Other Process Memory.

Class helpers and virtual methods – E2003 Undeclared identifier: ‘QueryInterface’/ ‘_AddRef’/’_Release’

Posted by jpluimers on 2018/06/20

Reminder to self: if you want to stay compatible with old (Pre Delphi XE) source code, then do not use virtual methods in class helpers.

Technically you can, as class helpers can inherit from other class helpers, but this is only supported as of Delphi XE.

In lower versions you get these errors as apparently the Delphi compiler tags an IInterface to the class helper compiler result:

[Error] Project1.dpr(14): E2003 Undeclared identifier: 'QueryInterface'
[Error] Project1.dpr(14): E2003 Undeclared identifier: '_AddRef'
[Error] Project1.dpr(14): E2003 Undeclared identifier: '_Release'
