fetching and pushing through git

[yarikoptic]

We have datalad dataset which we had curated for awhile and now decided to push to openneuro including our (partially squashed) git history. Major differences from the "templated" by openneuro dataset is use of MD5E backend, having our own datalad dataset uuid, and having custom .gitattributes file already. Nothing of that should effect git fetch though.

(deno) yoh@typhon:/mnt/DATA/data/yoh/1076_spacetop$ git fetch -v  openneuro-git
POST git-upload-pack (1022 bytes)
POST git-upload-pack (1022 bytes)
POST git-upload-pack (gzip 1822 to 983 bytes)
fatal: the remote end hung up unexpectedly

After I cloned into a separate directory and merged (allowing unrelated histories) the main branch into our master and tried to push, got following crash

(deno) yoh@typhon:/mnt/DATA/data/yoh/1076_spacetop$ git push openneuro-git master:main

and now after we did get all the objects through local

(deno) yoh@typhon:/mnt/DATA/data/yoh/1076_spacetop$ git fetch openneuro-git
