As the concept of patch text only makes sense for text files, we need to ignore binary files when searching with -G as well. The -S option of log looks for differences that changes the number of occurrences of the specified block of text (i.e. addition/deletion) in a file. As we want to keep the current behaviour, add a test to ensure it. Signed-off-by: Thomas Braun --- Changes since v1: - Merged both patches into one - Adapted commit messages - Added missing support for -a flag with tests - Placed new code into correct location to be able to reuse an existing optimization - Uses help-suggested -Ga writing without spaces - Uses orphan branches instead of cannonball cleanup with rm -rf - Changed search text to make it clear that it is not about the \0 boundary Documentation/gitdiffcore.txt | 2 +- diffcore-pickaxe.c | 6 ++++++ t/t4209-log-pickaxe.sh | 40 +++++++++++++++++++++++++++++++++++ 3 files changed, 47 insertions(+), 1 deletion(-) diff --git a/Documentation/gitdiffcore.txt b/Documentation/gitdiffcore.txt index c0a60f3158..059ddd3431 100644 --- a/Documentation/gitdiffcore.txt +++ b/Documentation/gitdiffcore.txt @@ -242,7 +242,7 @@ textual diff has an added or a deleted line that matches the given regular expression.
