Subject: tmpfile: modernize to 5.10.1+, note O_APPEND workaround
X-Git-Tag: v1.7.0~1706
X-Git-Url: http://www.git.stargrave.org/?a=commitdiff_plain;h=c51b6340a05cf11f7b0b3bb978288ade2f930c4a;p=public-inbox.git

tmpfile: modernize to 5.10.1+, note O_APPEND workaround

Once again we'll need O_APPEND on a temporary file, so note we
support it, here; since Perl 5.32 is way too new to depend on
our users having.
