GitHub – adaloveless/commonx: Delphi/Object Pascal Classes and Tools for just about everything and everyone.

Warning: I posted this without doing a proper copyright check on the linked github repository, and it looks like this library heavily copies code from copyrighted materials.

So better not use them, for one because they contain copyrighted material, and also because the copyrighted units are not current.

Git install tip for Windows installations: “”

Posted by jpluimers on 2020/07/21

When installing Git on Windows, you might want to change the default HTTPS transport back-end setting into “Use the Windows Secure Channel library” as it will use the Windows Certificate Stores for certificate validation. For Windows users, this allows for a more natural way to configure additional Root CS certificates (for instance the ones coming from Active Directory Domain Services).

If you later want to change this, then you can either re-run the installer, or perform these commands (based on the installer source):

To select the OpenSSL library:

config --system http.sslBackend openssl

To select the Windows Secure Channel library:

config --system http.sslBackend schannel

I do need to check out other ways of installing it (more on that in [WayBack] 5 Ways to Install Git on Windows · James Sturtevant), but for now I’m using the regular installer.

At first time install (subsequent installs will re-use the first-time install location without a way to overwrite them):

  • If you run that “As Administrator”, then it will install for all users (64-bit in C:\Program Files\Git, 32-bit in C:\Program Files (x86)\Git)
  • Otherwise in %LOCALAPPDATA%\Programs\Git which usually is in C:\Users\<username>\AppData\Local\Programs\Git).

Note that the actually executables are inside a bin subdirectory of the installation path.

Operant Conditioning by Software Bugs – Embedded in Academia

Posted by jpluimers on 2020/07/21

Good to remember both these:

[WayBack] Operant Conditioning by Software Bugs – Embedded in Academia which means when using a system, you subconsciously start behaving around it’s issues. This also happens when you the software you wrote the software for such a system: you hardly test the things that you broke.

The magic SysReq key on Linux systems running on PC-hardware allows you to sync/mount read-only/shutdown a system by keyboard (and many more options – see the Wikipedia list below). Do not forget to enable this as it is disabled by default. And remember that many laptops forego the SysReq key (as do Mac systems).

The order while holding Alt-SysReq down is S,U,B…

“error: invalid object 100644” “git svn”

Posted by jpluimers on 2020/07/14

A while back, while using “git svn”, on a Windows system, I got [Archive.is] “error: invalid object 100644” “git svn” – Google Search after statements like this:

# git svn rebase
error: refs/remotes/git-svn does not point to a valid object!
error: invalid object 100644 ac7df132f5bd7d639fc525f1f0204a546658d0c5 for 'Source/ToDoList/GX_ToDo.pas'
fatal: git-write-tree: error building trees
write-tree: command returned error: 128

# git svn fetch
error: refs/remotes/git-svn does not point to a valid object!
error: invalid object 100644 ac7df132f5bd7d639fc525f1f0204a546658d0c5 for 'Source/ToDoList/GX_ToDo.pas'
fatal: git-write-tree: error building trees
write-tree: command returned error: 128

In my case, regular git operations (like branching, committing, pushing, etc) worked fine, but git svn would fail.

One problem was that [Archive.is] “error: refs/remotes/git-svn does not point to a valid object” – Google Search only returned one un-meaningful result: [WayBack] gist:87613 · GitHub.

Luckily, I had a backup (though it was from a while ago as that VM had not been in use for quite some time) which is the first part in [WayBack] Git FAQ – Git SCM Wiki: How to fix a broken repo?.

Since I was still interested finding out how to resurrect, just in case this happens at a time the backups do not go back far enough, I tried the steps below.

The very first fixing step is to ensure you can quickly restore things, or even better: operate on a copy of the broken pieces. On Windows, robocopy /mir is my friend for this, in Linux rsync -avloz (although on some systems, -z crashes).

TL;DR from the fixing steps

Find out what problems you have, and in which order to fix them. Otherwise you will break more stuff and take longer to fix it.

In this case, two things failed: one on the git side, and one on the git svn side. Since git svn depends on git, the best approach is to fix the git problem first, then the git svn thing.

Fixing this manually try 1

Is WCF faster than ASP.NET Core? Of course not! Or is it?

Interesting:

How does WCF, a 13-year-old mega-abstraction framework hold up against the modern, lean, ASP.NET Core? You’d be surprised.

linux – How do I use sudo to redirect output to a location I don’t have permission to write to? – Stack Overflow

Posted by jpluimers on 2020/07/09

Various ways are explained at [WayBack] linux – How do I use sudo to redirect output to a location I don’t have permission to write to? – Stack Overflow.

Some are for simple commands and can be a one liner (for instance using tee, or executing a secondary shell).

Others are more suited for longer command sequences.

delphi – How to reset the download when the GetIt package manager fails? – Stack Overflow

Posted by jpluimers on 2020/07/08

Since GetIt is hardly, if at all documented, but has quite a few of problems, I will likely need to use this another time: [WayBack] delphi – How to reset the download when the GetIt package manager fails? – Stack Overflow

TL;DR:

Luis Navarro from Embacadero just explained to me:

Close the IDE, then delete the OmniThread folder from MyDocuments\Embarcadero\Studio\17.0\CatalogRepository After that, you have to edit the registry and delete also the Omnithread folder from HKEY_CURRENT_USER\SOFTWARE\Embarcadero\BDS\17.0\CatalogRepository\Elements
