I am of two minds here. The existing code is being more lenient than specified when they read stuff others wrote, but it still adheres to -1 when writing. Allowing random implementations to write random negative values will close the door for us to later update the specification to encode more informatin about these invalid entries by using negative value other than -1 here. I am OK with a reword to say "negative means invalid, and writers should write -1 for invalid entries", but without the latter half, this change is not justified. > diff --git a/Documentation/technical/index-format.txt > b/Documentation/technical/index-format.txt > index 9d25b30..2028a49 100644 > --- a/Documentation/technical/index-format.txt > +++ b/Documentation/technical/index-format.txt > @@ -161,8 +161,8 @@ GIT index format > this span of index as a tree. > > An entry can be in an invalidated state and is represented by having > - -1 in the entry_count field.
