Subject: avoid File::Temp::tempfile in more places
X-Git-Tag: v1.6.0~152
X-Git-Url: http://www.git.stargrave.org/?a=commitdiff_plain;h=67380a130f18b5b3abbee82346ff7c15185f41e8;p=public-inbox.git
avoid File::Temp::tempfile in more places
We can use open(..., undef) natively in Perl in t/import.t
In places where we need a pathname, the File::Temp OO API
gives us auto-unlinking for free.
