From 5482184c52d91e5d7806ea41243408ae1e299ca5 Mon Sep 17 00:00:00 2001 From: Michael Montalbo Date: Sat, 7 Mar 2026 01:02:16 +0000 Subject: [PATCH] line-log: route -L output through the standard diff pipeline `git log -L` has always bypassed the standard diff pipeline. `dump_diff_hacky()` in line-log.c hand-rolls its own diff headers and hunk output, which means most diff formatting options are silently ignored. A NEEDSWORK comment has acknowledged this since the feature was introduced: /* * NEEDSWORK: manually building a diff here is not the Right * Thing(tm). log -L should be built into the diff pipeline. */ Remove `dump_diff_hacky()` and its helpers and route -L output through `builtin_diff()` / `fn_out_consume()`, the same path used by `git diff` and `git log -p`. The mechanism is a pair of callback wrappers that sit between `xdi_diff_outf()` and `fn_out_consume()`, filtering xdiff's output to only the tracked line ranges. To ensure xdiff emits all lines within each range as context, the context length is inflated to span the largest range. Wire up the `-L` implies `--patch` default in revision setup rather than forcing it at output time, so `line_log_print()` is just `diffcore_std()` + `diff_flush()` with no format save/restore. Rename detection is a no-op since pairs are already resolved during the history walk in `queue_diffs()`, but running `diffcore_std()` means `-S`/`-G` (pickaxe), `--orderfile`, and `--diff-filter` now work with `-L`, and `diff_resolve_rename_copy()` sets pair statuses correctly without manual assignment. Switch `diff_filepair_dup()` from `xmalloc` to `xcalloc` so that new fields (including `line_ranges`) are zero-initialized by default. As a result, diff formatting options that were previously silently ignored (e.g. --word-diff, --no-prefix, -w, --color-moved) now work with -L, and output gains `index` lines, `new file mode` headers, and funcname context in `@@` headers. This is a user-visible output change: tools that parse -L output may need to handle the additional header lines. The context-length inflation means xdiff may process more output than needed for very wide line ranges, but benchmarks on files up to 7800 lines show no measurable regression.
