We pair lines for highlighting based on their position in the hunk. So
we should never see two identical lines paired, like:
-one
-two
+one
+something else
which would pair -one/+one, because that implies that the diff could
easily be shrunk by turning line "one" into context.
But there is (at least) one exception: removing a newline at the end of
a file will produce a diff like:
-foo
+foo
\No newline at end of file
And we will pair those two lines. As a result, we end up marking the
whole line, including the newline, as the shared prefix. And there's an
empty suffix.
The most obvious bug here is that when we try to print the highlighted
lines, we remove the trailing newline from the suffix, but do not bother
with the prefix (under the assumption that there had to be a difference
_somewhere_ in the line, and thus the prefix would not eat all the way
up to the newline). And so you get an extra line like:
-foo
+foo
\No newline at end of file
This is obviously ugly, but also causes interactive.diffFilter to
(rightly) complain that the input and output do not match their lines
1-to-1.
This could easily be fixed by chomping the prefix, too, but I think the
problem is deeper. For one, I suspect some of the other logic gets
confused by forming an array with zero-indexed element "3" in a
3-element array. But more importantly, we try not to highlight whole
lines, as there's nothing interesting to show there. So let's catch this
early in is_pair_interesting() and bail to our usual passthrough
strategy.

Commit f697d08 (gitk: i18n: use "Gitk" as package name in POT file,
2026-03-19) updated the generated POT template to use "Gitk" in its
Project-Id-Version header. Several existing PO files still carry older
header values such as "git" or "git-gui", so they do not consistently
identify themselves as Gitk translations.
Update the Project-Id-Version field in all Gitk PO files so that they
identify the Gitk project consistently.
The "Project-Id-Version" field in the PO header helps tools identify
which project a PO file belongs to. For example, Git's
"git-po-helper" uses it to choose project-specific checks and POT
handling rules. Without this change, some Gitk PO files are
misidentified because their headers still refer to other projects.

"po/gitk.pot" is generated from the source for translation maintenance.
Ignore it in the working tree so regenerating the template does not

Use "Gitk" instead of the placeholder "PACKAGE" in the header of the
generated po/gitk.pot file. In particular, the "Project-Id-Version"
field in the header entry should be set to:
"Project-Id-Version: Gitk\n"
New PO files generated from this POT file will inherit that package
name.

Every compilation unit in Git is expected to include "git-compat-util.h"
first, either directly or indirectly via "builtin.h". This header papers
over differences between platforms so that we can expect the typical
POSIX functions to exist. Furthermore, it provides functionality that we
end up using everywhere.
This header is thus quite heavy as a consequence. Preprocessing it as a
standalone unit via `clang -E git-compat-util.h` yields over 23,000
lines of code overall. Naturally, it takes quite some time to compile
all of this.
Luckily, this is exactly the kind of use case that precompiled headers
aim to solve: instead of recompiling it every single time, we compile it
once and then link the result into the executable. If include guards are
set up properly it means that the file won't need to be reprocessed.
Set up such a precompiled header for "git-compat-util.h" and wire it up
via Meson. This causes Meson to implicitly include the precompiled
header in all compilation units. With GCC and Clang for example this is
done via the "-include" statement [1].
This leads to a significant speedup when performing full builds:
Benchmark 1: ninja (rev = HEAD~)
Time (mean ± σ): 14.467 s ± 0.126 s [User: 248.133 s, System: 31.298 s]
Range (min … max): 14.195 s … 14.633 s 10 runs
Benchmark 2: ninja (rev = HEAD)
Time (mean ± σ): 10.307 s ± 0.111 s [User: 173.290 s, System: 23.998 s]
Range (min … max): 10.030 s … 10.433 s 10 runs
Summary
ninja (rev = HEAD) ran
1.40 ± 0.02 times faster than ninja (rev = HEAD~)
