libssh-delphi will migrate from Mercurial on BitBucket to git on GitHub soon (or finding about “fatal: repository … not found”, “MSVCR120.dll is missing” and “D3DCOMPILER_47.dll is missing” when prepping a fresh VM for a presentation)

Posted by jpluimers on 2018/03/08

When git on Windows suddenly gives you this when the repository URL opens fine in Chrome:

C:\Users\jeroenp\Versioned>git clone
Cloning into 'libssh2-delphi'...
remote: Not Found
fatal: repository '' not found

but this worked fine:

C:\Users\jeroenp\Versioned>git clone
Cloning into 'GExperts'...
remote: Counting objects: 12031, done.
remote: Total 12031 (delta 0), reused 0 (delta 0), pack-reused 12031R
Receiving objects: 100% (12031/12031), 9.77 MiB | 1.36 MiB/s, done.

Resolving deltas: 100% (9284/9284), done.

I first thought “huh?”.

Then I remembered: this was a Mercurial repository, but I hardly use Mercurial any more…

C:\Users\jeroenp\Versioned>hg clone
destination directory: libssh2-delphi
requesting all changes
adding changesets
adding manifests
adding file changes
added 30 changesets with 56 changes to 25 files
updating to branch default
12 files updated, 0 files merged, 0 files removed, 0 files unresolved

Since I wanted to switch away from bitbucket for a long time anyway, it was time to say goodbye and find out how to make the conversion to git.

A quick search revealed there were many tedious manual ways involving command-lines: [WayBack] Convert Mercurial project to Git – Stack Overflow

But then I found out that github can fully automagically import a Mercurial Repository (of course without the BitBucket attached bells and whistles like issue tracker):

So it is now at with one user still to be mapped at … libssh2-delphi/import/authors: Zeljko Marjanovic. If I ever get in contact with him (I tried over the last 2 years), then I will add him.

For now, I will be in touch with Vadum Lou (a.k.a., full nameVadim V. Lopushansky) who already made another manually copied fork and get his additions integrated.

I might redo the conversion process later on as at least some of his submissions are at least partially in a Mercurial pull request.

Then I need to merge the develop branch into the master branch and prepare a release.

Oh: if it fails to debug in Delphi, then run the EXE alone. You will get an error like this:

SftpClientDemo.exe - System Error
The program can't start because MSVCR120.dll is missing from your computer. Try reinstalling the program to fix this problem.

I need to document this better in the the underlying libssh2 DLLs require the Visual Studio 2013 C++ run-time library to be installed. The latest version I could find as of writing is vcredist_x86.exe version 12.0.40649.5 from the Update for Visual C++ 2013 and Visual C++ Redistributable Package at (download selection) or (direct download).

I need to update If a program you wrote can’t start becuase MSVCR*.dll is missing, then you forgot to ship the Visual C++ runtime… from 2012 on this as well as there are more versions available now than listed there.

Another error I got was the one below when running .NET stuff, but that might be because Windows Update was in progress:

SourceTree.exe - System Error
The program can't start because D3DCOMPILER_47.dll is missing from your computer. Try reinstalling the program to fix this problem.

Later: yes, that was indeed fixed during Windows update. Apparently, Microsoft has an update installation order issue or a dependency requirement issue where part of .NET depends on that DLL, even though it is not yet present.

Why do 90% of the Visual Studio Tools and Extensions make it so hard to update…

Posted by jpluimers on 2018/03/08

Worth repeating my [WayBack] Friday developers rant… Why do 90% of the Visual Studio Tools and Extensions make it so !@#$!@#$ hard to update.… – Jeroen Wiert Pluimers – Google+:

Why do 90% of the Visual Studio Tools and Extensions make it so !@#$!@#$ hard to update as for *each* tool, you have to:

1. start Visual Studio (which doesn’t show progress, sometimes starts fast and sometimes takes a minute)
2. go to “Tools” menu, then to the “Extensions and Updates…” entry
3. in the dialog, browse to the bottom entry of the leftmost treeview (“Updates”) and click on it (as you cannot reach it by keyboard)
4. click the “Update” button for the topmost tool (it downloads with your default web browser which takes focus away from Visual Studio)
5. switch back to Visual Studio
6. close the “Extensions and Updates…” dialog
7. quit Visual studio
8. find the downloaded updater in your web browser (all !@#*!@# web browsers do this in a different way)
9. update (specify options, choose UAC elevation when needed, etc, etc)
10. wait for the update to complete (.NET Core 1.0.1, Microsoft Azure SDK for .NET and Microsoft SQL Server Data Tools take ages to complete and for most of the time stay at 95% of the progress bar for minutes. It’s called progress bar for a reason, track your progress evenly and hurry up!)
11. start over at step 1 for the next update

10 )!@($#*%&@# manual steps PER UPDATE

Afterwards you need to clean all the downloaded installers as they often are partial web-installers which cannot be re-used

I want a “update all with default settings” button….
