Repository file size #512
Description
Activity
Thanks for the detailed report!
Hmm, one possibility is that it's just many rounds of many UFO font sources, each with many small files.
I'm not really a git wizard. Do you (or anyone else) have any suggestions of what to do to trim down the size of git repos?
I have no idea how to fix this. I'm going to do some reading and try to figure it out.
Okay I found a possible solution. I'm documenting the process here but will make a fork of the repo and try it out there. If everything has worked as desired, I'll open a pull request.
My working hypothesis is that the offending files seems to be
- A
.sketchfile which was prototyping the Noordzij cube (src/proofs/final-specimen/create-noordzij-cube-6_sides.sketch) - A
.zipfile in thefontsdirectory containing all the binaries at some point
While the files inherently aren't equal to a couple gigabytes, the deltas that reference them over several commits could be multipliers.
Process:
-
Run
sh <path-to>/FindBlobs.sh. This will identify files in history above a certain byte size. -
Once the files have been identified run the following with the filename:
- Run
git filter-branch --index-filter 'git rm -r --cached --ignore-unmatch <folder/file name>' --prune-empty
- Run
-
Once filtering has been completed run all the following commands in sequence:
git for-each-ref --format='delete %(refname)' refs/original | git update-ref --stdingit reflog expire --expire=now --allgit gc --aggressive --prune=now

Hi @arrowtype I tried a couple of things but they didn't work. I think you might need to talk to someone who has a deeper understanding of version control to help out with this.
Looking at this problem, as a matter of policy, we've made a change (internally within Universal Thirst) to not upload font binaries, PDFs, images and other binaries in new repos.
Feel free to close this and apologies for the bother :)
Reacted by Stephen NixonOf course I cannot speak for @arrowtype, but if I were the author of this repo, I would not find anything about this thread that was a bother or needs apology. I think many people would be genuinely curious and interested to see if there is something that can be done about the unexpectedly large size.
Edit:
I guess 4 GB including history is not so bad, judging by this document about building a different font:
Note that this repo has a 30+ GB commit history. If you only want the current files and future changes, you can avoid downloading so much by cloning the repo with a --depth limit.
It then goes on to give an example of a limited-depth clone command for that font. So, it would seem the size of the (main, official) Recursive repo is actually not all that unexpected or even unusually large. And maybe the normal thing to do for people who want to play around with a local clone is to not download all the history.
Reacted by Kalapi Gajjar and Stephen NixonFor people who don't need the whole repo history, which is likely no one outside of @arrowtype, use a shallow clone.
Get only the last 20 commits across all branches:
git clone --depth=20 --no-single-branch https://github.com/arrowtype/recursive.gitOnly the most recent commit and only the main branch:
git clone --depth=1 https://github.com/arrowtype/recursive.gitThis shallowest clone is best for one-off or consume-only copies, because not all git commands will work later, e.g. switch to a branch created before the cloning date.
Disclaimer: I'm not all that git proficient, but learned this trick out of necessity when working with a 20 year old project with very long clone times.
Reacted by Stephen Nixon and Kalapi GajjarHey, thanks so much for the feedback and insights, @kalapi, @jkyeung, and @maphew! Sorry I've been slow to respond, but I truly appreciate it.
I will try to add the
depthtip to the readme, for people that may see it.I suspect the thing that might take the most time in downloading is that in this repo, I have been committing changes to "build prepped" UFOs, and I have done many, many builds. Each UFO is thousands of tiny files, so I think that probably stacks up a lot. I now put such prepped sources in the .gitignore file of font repos.
I'll try to look further into the resources posted by @kalapi to test out pruning some of those unnecessary sources.
- @maphew you explained things well! Is it alright if I basically copy-paste your advice into the readme?Oh, yes of course. Except, I have to recant, it's not good advice post 2020! Use a _partial clone_ instead: `git clone --filter=blob:none (url)` Shallow clones (using `depth` parameter) should only be used in "use and discard" scenarios such as Continuous Integration pipelines. Shallow is still the fastest cloning mechanism but unreliable for any later git work other than git pull.

Problem description
Hi @arrowtype, this is not a bug report, more like a meta issue with the repository itself. I was doing some winter housekeeping on my Mac and found that the Recursive repository is 3.98 GB! And this isn't because of a file (or group of files) in the current state of the repo but probably because of past commits in the hidden
.gitfolder. Honestly I don't know what these files represent. I wonder if you have any insight?Expected behavior
No effect on font binaries
Screenshots
To Reproduce
I use a Mac app called Grand Perspective which helps visualise large data blocks on the hard drive. One of the larger chunks was the Recursive repository folder and I was really surprised.
