Git Stash Blooper (Could not restore untracked files from stash)

The other day I accidentally did a git stash -a, which means it stashes *everything*, including ignored output files (target, build, classes, etc).

Ooooops..


What I meant to do was git stash -u, meaning stash modifications plus untracked new files.

Anyhows, I ended up with a big fat stash I couldn't get back out. Each time I tried, I got something like this:

.../target/temp/dozer.jar already exists, no checkout
.../target/temp/core.jar already exists, no checkout
.../target/temp/joda-time.jar already exists, no checkout
.../target/foo.war already exists, no checkout
Could not restore untracked files from stash

No matter how I tried checking out different revisions (like the one where I actually made the stash), or using --force, I got the same error. Now these were one of those "keep cool for a second, there's a git way to fix this"situation. I figured:

A stash is basically a commit.

If we look at my recent commits using
  git log --graph --all --decorate --oneline

...we see something like:


* dd7b26b (master) Extract method
* b0d0487 Rename one of the assertScreenForEvent methods
* ddbb532 Use strong typing for Events
| *-.   0374bd1 (refs/stash) WIP on master: d7fe9ab new class Event
| |\ \  
| | | * 2a958c1 untracked files on master: d7fe9ab new class Event
| | * 51510de index on master: d7fe9ab new class Event
| |/  
| * d7fe9ab (HEAD) new class Event
| * c59f0f3 Extract method
| * 74a987f Rename one of the assertScreenForEvent methods
| * 75e98b7 Use strong typing for Events
|/  
| * 40b5b29 (origin/master, origin/HEAD) added language-chooser


See my fatal stash up there? It's the 0374bd1. It looks a bit funky cause I was doing some rebasing at the same time (it has three parents which is actually one commit that was rewritten twice).

So following my line of thought: The stash is a commit gone bad. I need to reset it and then stash it again, without the -a flag.

So here we go. First check out the stash itself:

10093  git checkouto 0374bd1

And then, present it's a botched commit, and reset to previous commit, keeping the contents:

git reset HEAD~1

Goodie, got the stash back as local changes. Now, let's stash properly:

git stash -u

Voila. After this, the stash popped without problems.

I realize I could have probably unstashed the big failed stash if I had cleaned the repo first with git clean -dfx, but then I would've lost a lot of annoying things like IDEA config files, etc.

Hope this post will help out anyone googling the error message.

Encrypting and Decrypting with Spring

I was recently working with protecting some sensitive data in a typical Java application with a database underneath. We convert the data on its way out of the application using Spring Security Crypto Utilities. It "was decided" that we'd be doing AES with a key-length of 256, and this just happens to be the kind of encryption Spring crypto does out of the box. Sweet!

The big aber is that whatever JRE is running the application has to be patched with Oracle's JCE in order to do 256 bits. It's a fascinating story, the short version being that U.S. companies are restricted from exporting various encryption algorithms to certain countries, and some countries are restricted from importing them.

Once I had patched my JRE with the JCE, I found it fascinating how straight forward it was to encrypt and decrypt using the Spring Encryptors. So just for fun at the weekend, I threw together a little desktop app that will encrypt and decrypt stuff for the given password and sa…

Managing dot-files with vcsh and myrepos

Say I want to get my dot-files out on a new computer. Here's what I do:

# install vcsh & myrepos via apt/brew/etc
vcsh clone https://github.com/tfnico/config-mr.git mr
mr update

Done! All dot-files are ready to use and in place. No deploy command, no linking up symlinks to the files. No checking/out in my entire home directory as a Git repository. Yet, all my dot-files are neatly kept in fine-grained repositories, and any changes I make are immediately ready to be committed:

config-atom.git
    -> ~/.atom/*

config-mr.git
    -> ~/.mrconfig
    -> ~/.config/mr/*

config-tmuxinator.git  
    -> ~/.tmuxinator/*

config-vim.git
    -> ~/.vimrc
    -> ~/.vim/*

config-bin.git   
    -> ~/bin/*

config-git.git          
    -> ~/.gitconfig

config-tmux.git  
    -> ~/.tmux.conf    

config-zsh.git
    -> ~/.zshrc

How can this be? The key here is to use vcsh to keep track of your dot-files, and its partner myrepos/mr for operating on many repositories at the same time.

Always use git-svn with --prefix

TLDR: I've recently been forced back into using git-svn, and while I was at it, I noticed that git-svn generally behaves a lot better when it is initialized using the --prefix option.

Frankly, I can't see any reason why you would ever want to use git-svn without --prefix. It even added some major simplifications to my old git-svn mirror setup.

Update: Some of the advantages of this solution will disappear in newer versions of Git.

For example, make a standard-layout svn clone:

$ git svn clone -s https://svn.company.com/repos/project-foo/

You'll get this .git/config:

[svn-remote "svn"]
        url = https://svn.company.com/repos/
        fetch = project-foo/trunk:refs/remotes/trunk
        branches = project-foo/branches/*:refs/remotes/*
        tags = project-foo/tags/*:refs/remotes/tags/*

And the remote branches looks like this (git branch -a):
    remotes/trunk
    remotes/feat-bar

(Compared to regular remote branches, they look very odd because there is no remote name i…

Joining eyeo: A Year in Review

It's been well over a year since I joined eyeo. And 'tis the season for yearly reviews, so...

It's been pretty wild. So many times I thought "this stuff really deserves a bloggin", but then it was too inviting to grab onto the next thing and get that rolling.

Instead of taking a deep dive into some topic already, I want to scan through that year in review and think for myself, what were the big things, the important things, the things I achieved, and the things I learned. And then later on, if I ever get around to it, grab one of these topics and elaborate in a dedicated blog-post. Like a bucket-list of the blog posts that I should have written. Here goes:
How given no other structures, silos will grow by themselves This was my initial shock after joining the company. Only a few years after taking off as a startup, the hedges began growing, seemingly almost by themselves, and against the will of the founders. I've worked in silos, and in companies without the…

The End of GitMinutes (my podcast)

I'm just about ship GitMinutes episode 46, which is going to be the final episode. I'll just paste the outro script here, as it sums up the sentimental thoughts pretty well:

I’m happy to have finally finished [publishing the last episodes from Git-Merge 2017], just in time before Git-Merge 2018 takes place in March. I won’t be going there myself, so I’m counting on someone else to pick up the mic there.

It’s sad to be shipping this one as it is probably the last GitMinutes episode ever. To go a bit down memory lane, 6 years ago, my daughter was born, and as I used a little of that paternity leave to set up my podcasting infrastructure and produce the first few episodes. Initially it was just going to be 10 episodes and call the experiment finished. Instead, I got to 46 episodes, the last dozen or so lazily tailing the last few Git-Merge conferences.

To every one of my guests, thank you so much again for coming on to share your passion in this little niche of computer science a…
