How to remove all files from GIT repo history with path having colon : in filename? – Debian

I have ISCSI node filenames with colons stored in GIT repository on Debian 10 Linux.

Example:

'iscsi/nodes/iqn.2000-01.com.synology:NAS01-DS916.nas/ff11::111:11ff:ff1f:1ff1,3260,1/default'
'iscsi/send_targets/1.2.3.4,3260/iqn.2000-01.com.synology:NAS01-DS916.nas,ff11::111:11ff:ff1f:1ff1,3260,1,default'

But checkout fails on Windows, because the colon is invalid character in Windows filename.

I get following GIT errors at Windows checkout:

error: invalid path 'iscsi/nodes/iqn.2000-01.com.synology:NAS01-DS916.nas/ff11::111:11ff:ff1f:1ff1,3260,1/default'
...
error: invalid path 'iscsi/send_targets/1.2.3.4,3260/iqn.2000-01.com.synology:NAS01-DS916.nas,ff11::111:11ff:ff1f:1ff1,3260,1,default'

Questions:

1) How to list all path having colon : in full GIT repo history?

2) How to remove all files from GIT repo history with path having at least one colon : in filename?

SOLUTION for 1) :

Works1:

git log --all --name-only -m --pretty= -- '*:*' | sort -u

Works2 (only for the named repo master):

git ls-tree -r master --name-only | grep ":"

Works3: Finally I used this to list files with colons in filename:

git log --format="reference" --name-status --diff-filter=A "*:*" >/opt/git_repo_files_w_colons.txt

UPDATE1 for 2):

I got

Aborting: Refusing to destructively overwrite repo history since
this does not look like a fresh clone.
  (expected freshly packed repo)
Note: when cloning local repositories, you need to pass
      --no-local to git clone to avoid this issue.
Please operate on a fresh clone instead.  If you want to proceed
anyway, use --force.

when executing

git filter-repo --invert-paths --path-match "*:*"

UPDATE2 for 2) :

Clone a copy of the repo:

git clone --no-local /source/repo/path/ /target/path/to/repo/clone/
# Cloning into '/target/path/to/repo/clone'...
# remote: Enumerating objects: 9534, done.
# remote: Counting objects: 100% (9534/9534), done.
# remote: Compressing objects: 100% (4776/4776), done.
# remote: Total 9534 (delta 4216), reused 8042 (delta 3136), pack-reused 0
# Receiving objects: 100% (9534/9534), 7.40 MiB | 17.08 MiB/s, done.
# Resolving deltas: 100% (4216/4216), done.

Remove the files with colon from repo history:

git filter-repo --invert-paths --path-match "*:*"
# Parsed 591 commits
# New history written in 0.47 seconds; now repacking/cleaning...
# Repacking your repo and cleaning out old unneeded objects
# HEAD is now at 501102d daily autocommit
# Enumerating objects: 9534, done.
# Counting objects: 100% (9534/9534), done.
# Delta compression using up to 8 threads
# Compressing objects: 100% (3696/3696), done.
# Writing objects: 100% (9534/9534), done.
# Total 9534 (delta 4216), reused 9534 (delta 4216), pack-reused 0
# Completely finished after 1.33 seconds.

Checking still shows filenames with colon:

git log --format="reference" --name-status --diff-filter=A "*:*"
# A    iscsi/nodes/iqn.2000-01.com.synology:NAS01-DS916.nas/ff11::111:11ff:ff1f:1ff1,3260,1/default
# ...

Unfortunately it seems filter-repo was executed, but log still lists filenames with colon 🙁

    1. How to list all path having colon : in full GIT repo history?

    You may be out of luck here. There’s more talk about this issue and workarounds in Windows here.

    1. How to remove all files from GIT repo history with path having at least one colon : in filename?

    Please be careful with this approach if you are developing with others. When existing branches are modified in the origin, it will cause a lot of conflicts when others try to pull them down.

    But if you are ok to proceed, you can try an approach here.

    link #1 did not provide solution to list paths having colo

    Check:

    git ls-tree -r master --name-only | grep ":"

    But the approach suggested was to reset all files without ":", and delete the rest:

    git ls-tree -r master --name-only | grep -v ":" | xargs git reset HEAD
git commit -m "deleting all files with a colon in the name"
git restore -- .

    The OP klor reports listing those files with a git log pretty format "reference" (which is <abbrev-hash> (<title-line>, <short-author-date>)):

    git log --format="reference" --name-status --diff-filter=A "*:*" >/opt/git_etc_repo_files_w_colons.txt

    The OP suggested:

    # Clone repository, to be executed on a safe repo:
git clone --no-local /source/repo/path/ /target/path/to/repo/clone/
# Cloning into '/target/path/to/repo/clone'...

# List files with colon to check result:

# Empty result, so git filter-repo was successful, filenames with colon were removed!

    The better approach might be to not check those files out on Windows,see the sparse checkout facility, or to rename them with characters Windows can handle, but to answer the questions as asked:

    1. How to list all path having colon : in full GIT repo history?
    git log --all --name-only -m --pretty= -- '*:*' | sort -u
    1. How to remove all files from GIT repo history with path having at least one colon : in filename?
    git filter-branch --prune-empty --index-filter '
        git ls-files "*:*" | git update-index --remove --stdin
' -- --all

    which will rewrite your entire history starting from the first commit you have to change. Do this in a scratch clone.
