device files should be handled by git

0 votes

I have a disk image of a small embedded device whose root file system I'd like to check-in to git as a means of distributing its GPL'd software. In that disk image are device files, which GIT studiously ignores. If symlinks are handled (contents being the path that the symlink points at), I don't see why device files can't be handled (contents being the type (char or block) and the major and minor device number). TAR, for example, handles this fine, except that using tar in git sort-of goes against the granularity of the objects being modified (like adding a bunch of extra "sd??" devices), such that you are modifying a whole tar ball instead of the individual (device) files.

Is there a reason not to handle device files other than "its not traditional"? That's the only reason given in google or the IRC channel.

In linux you can't create device files if your not root. On windows those files won't even exists (afaik).

Wouldn't this be very unportable and hard to use (meaning that you need to handle your git repo as root or give git setuid root)?

Device files will probably never be supported by Git for the reasons mentioned by Fredrik. If anything, etckeeper ( would be a much more appropriate place to support this, although I don't think it currently does.
Alternatively, you could follow the suggestions of (and elsewhere), and write a script for generating the device files, rather than storing them as-is.

Recently I had to write some automation scripts and I found that git reset --hard actually restores each file's permissions.

That is causing both the created and the last-modified dates of the file to get changed to the time of the git reset.

This behavior is easy to demonstrate:

echo "test" > myfile
chmod 777 myfile

git add myfile && git commit -m "Test" & the only solution I'm able to think about is actually restoring the permissions of each file to the ones git thinks they should have before doing the git reset.

Maybe I'm wrong and there is a way for doing what I want, if so, please correct me. But if there isn't, should this be implemented? Are there any reasons for not doing it?

I have my global git config pager set to 'cat', but when I do a "git help ", it still uses a pager. This is especially irksome in emacs shell buffers, where I am most of the time. I know I can do a M-x man -> git-, but wondered if this was a bug or user error. ("git --no-pager help " does the same.)

% git --no-pager help log
WARNING: terminal is not fully functional

When I update my branch from master it pulls down several files, including some sass files. When I compile, however, gulp alerts me that I am missing .scss files.

I tested this by creating a new fresh branch and running gulp sass. This time there were no errors and I saw the missing .scss had been brought in.

Would anyone know why, on update, I am only getting some of the files from master?

I work on some files and push/merge them to the remote server. Sometimes I get merge conflicts on those files and have to fix them. That's completely fine. I get that.

What I don't understand is that sometimes during this process I will get merge conflicts in files _I have never touched_. In fact they are in a completely different series of directories to the one I am working on and someone else project entirely. How am I meant to know how to fix these? I dont know what the other developer wanted to do and if they have done it right.

I thought git only merged/pushed the files you have changed? If someone else has changed Group A files on the remote repo, why must I change my local Group A files when I am _pushing _completely different set of Group B files?

Sure, Id understand if I were pulling files down to my local and had to resolve merge conflicts then, but this isn't happening when I push the files up.

Any help or advice is much appreciated. Sorry if I sound frustrated - I am really trying hard to get my head round this whole git thing but its just so weird.

I wanted to avoid push if any of the files is deleted from the local git clone area. Can anyone please help me with that?

I am using Stash for repository management.
