Subject: gitview: Define __slots__ for Commit
X-Git-Tag: v1.5.3-rc0~146
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=225696af2ceaa2e06345954003eda742a76c4e0a;p=git.git

gitview: Define __slots__ for Commit

Define __slots__ for the Commit class. This reserves space in each Commit
object for only the defined variables. On my system this reduces heap usage
when viewing a kernel repo by 12% ~= 55868 KB.
