blame,cat-file: Demonstrate --textconv is wrongly running converter on symlinks
git blame --textconv is wrongly calling the textconv filter on symlinks: symlinks are stored as blobs whose content is the target of the link, and blame calls the textconv filter on a temporary file filled-in with the content of this blob. For example: $ git blame -C -C regular-file.pdf Error: May not be a PDF file (continuing anyway) Error: PDF file is damaged - attempting to reconstruct xref table... Error: Couldn't find trailer dictionary Error: Couldn't read xref table Warning: program returned non-zero exit code #1 fatal: unable to read files to diff That errors come from pdftotext run on symlink.pdf being extracted to /tmp/ with one-line plain-text content pointing to link destination. So several failures are demonstrated here: - git cat-file --textconv :symlink.bin # also HEAD:symlink.bin - git blame --textconv symlink.bin - git blame -C -C --textconv regular-file # but also looks on symlink.bin At present they all fail with something like. E: /tmp/j3ELEs_symlink.bin is not "binary" file NOTE: git diff doesn't try to textconv the pathnames, it runs the textual diff without textconv, which is the expected behavior.
