How to Retrieve the SVN URL of a Removed File in git-svn

When working with git-svn on an SVN subdirectory checkout, getting the SVN URL for a deleted file is totally doable with a few git-svn commands—even scriptable ones. Here's how:

Direct Approach (Single File)

First, find any commit where the file still existed. You can use git log --full-history -- path/to/removed_file.py to list commits involving the file, then pick a commit hash where it was present (e.g., the last commit before deletion).

Once you have that commit hash, run:

git svn info --url <COMMIT_HASH>:path/to/removed_file.py

This will spit out the full SVN URL for the file as it existed in that commit. git-svn retains the SVN metadata for files in commits where they were present, so this works even if the file is gone from your current working tree.

Scriptable Method (Automate the Process)

To make this repeatable (great for scripts), you can automate finding the last commit where the file existed and fetching its SVN URL in one go:

#!/bin/bash
FILE_PATH="path/to/removed_file.py"

# Get the last commit where the file was present
LAST_COMMIT=$(git rev-list --full-history --max-count=1 -- "$FILE_PATH")

if [ -z "$LAST_COMMIT" ]; then
    echo "Error: No commit history found for $FILE_PATH"
    exit 1
fi

# Retrieve the SVN URL from that commit
git svn info --url "$LAST_COMMIT:$FILE_PATH"

How this works:

git rev-list --full-history --max-count=1 -- $FILE_PATH finds the most recent commit where the file was part of the repository (even if it was deleted later).
Passing that commit hash with the file path to git svn info --url pulls the original SVN URL from the commit's metadata.

Using the URL to Access Older SVN History

Once you have the full SVN URL, you can use the SVN revision number from your git log entries (the suffix in git-svn commit messages like git-svn-id: ...@1234) to query earlier history with:
