Subject: test: increase buffer size for http/data_length_constraints to trigger EPIPE
X-Git-Tag: release-2.1.6-beta~70^2~7
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=0792e1e7a775f95b395a45c78052c842817749c0;p=libevent

test: increase buffer size for http/data_length_constraints to trigger EPIPE

With greater buffer it can't be written with one writev(2), and hence we can
trigger more tricky cases, like calling writecb/readcb more then once.
