“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?

Posted by jpluimers on 2020/07/14

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

Time to look back at the Spectre vulnerabilities.

Always read the comments (:

Cool tip by Paul Irish (but remember it will dump the binary curl output as well) at [WayBack] How can I debug git/git-shell related problems? – Stack Overflow:

There are a few GIT_TRACE options, beyond the core one. Here’s the über-verbose option: set -x; GIT_TRACE=2 GIT_CURL_VERBOSE=2 GIT_TRACE_PERFORMANCE=2 GIT_TRACE_PACK_ACCESS=2 GIT_TRACE_PACKET=2 GIT_TRACE_PACKFILE=2 GIT_TRACE_SETUP=2 GIT_TRACE_SHALLOW=2 git pull origin master -v -v; set +x
