Git Patch - deleted file mode Header
A deletion of an executable file, so the `deleted file mode 100755` header records the mode the file had rather than the mode to create. A patcher that writes an empty file here instead of unlinking leaves a broken executable behind.

Subject: [PATCH] chore: drop the 2019 CSV import script
The cutover finished in January; nothing calls this any more.

What is a .patch file?
A .patch file is a unified diff packaged for transmission, most often as produced by `git format-patch`. Beyond the diff itself it carries an email-style header with the author, date, and commit subject, a commit message body, per-file `diff --git` headers recording renames and mode changes, and hunk headers of the form `@@ -old,count +new,count @@`. Applying it reconstructs a specific change against a specific before-state.
How to use this file
Use an example .patch file to test patch application, code-review renderers, and diff parsers: exercising renames, mode changes, binary hunks, added and deleted files, and the `\ No newline at end of file` marker that naive parsers silently drop.
How to use this file for testing
“Git Patch - deleted file mode Header” is a deterministic Testaroo fixture for Visual diff / regression, Code parsing, Editor testing. A/B image twins with controlled pixel changes, anti-alias variants, and UI chrome crops for screenshot diff and visual regression tools.
Documented properties for this file: seed 20260807 · UTF-8 · LF. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such, expect parsers to fail loudly rather than silently accept them.
Diff and patch fixtures name their target paths and the exact edge case they exercise, rename, mode change, binary hunk, CRLF↔LF, or missing trailing newline. Apply or render them against the documented before-state; every author, path, and hash is fictional.
Treat A/B twins as a visual regression unit: run your pixel or perceptual diff, assert a non-zero delta on the changed twin, and keep thresholds calibrated against the documented change kind in specs.

- patchGit Format-Patch Series - 0000 Cover LetterThe `--cover-letter` message git writes ahead of a series: a `[PATCH 0/3]` subject, a shortlog of the authors and their subjects, and the combined diffstat, but no diff of its own. Series tooling has to recognise it as metadata and not try to apply it.

- patchGit Patch - Copy Detection at similarity index 85%`copy from`/`copy to` headers, produced only when copy detection is enabled with `-C`. The source file still exists afterwards, which is the whole difference from a rename, and the difference a parser that maps both header pairs onto one 'moved' concept silently erases.
- patchGit Patch - Pure Rename at similarity index 100%A rename with no content change at all: `similarity index 100%`, `rename from`, `rename to`, and then nothing, no index line and no hunks. This is the single most common patch shape that naive parsers lose, because there is no `@@` anywhere in the file section.
