search for: add_head

Hi... Here''s a working Perl script that I want to be able to do in Ruby: use WWW::Mechanize; my $url = "http://host/tt?name=chris"; my $mech = WWW::Mechanize->new(); $mech->add_header( Referer => "http://chrismcmahonsblog.blogspot.com" ); $mech->add_header( Cookie => "messageid=170118; memberid=1007"); $mech->get($url) so the header values for Referer and Cookie are passed with the HTTP GET. There seems to be an add_field method in mechanize.r...

From: "Michael S. Tsirkin" <mst at redhat.com> virtio ring was changed to return an error code on OOM, but one caller was missed and still checks for vq->vring.num. The fix is just to check for <0 error code. Long term it might make sense to change goto add_head to just return an error on oom instead, but let's apply a minimal fix for 2.6.35.

I did some searching in the archive, but found only one message with this same question and no answer. Hopefully it's a simple config problem. When the Caller-ID is delivered, it is surrounded by double-quotes, like this: "ATA-57 1" On long caller-id strings, the last character is cut off to make room for the leading double-quote: "BudgeTone 1234 instead of BudgeTone

OK, so I've spent a few days benchmarking. Turns out 80% of virtio_add_buf cases are uni-directional (including the always-performance-sensitive networking code), and that gets no performance penalty (though tests with real networking would be appreciated!). I'm not reposting all the "convert driver to virtio_add_outbuf()" patches: just the scsi one which I didn't have

I'm handling mail for several domains, let's call them a.com, b.com, and c.com. I have certificates for each of these domains individually via certbot (letsencrypt) and nginx is happy with all of that. Since I initially configured the site to handle mail only for a.com, my /etc/postfix/main.cf file currently has these two lines: smtpd_tls_cert_file =

I resurrected these patches after prompting from Andy Lutomirski's recent patches. I put them on the back-burner because vring_bench had a 15% slowdown on my laptop: pktgen testing revealed a speedup, if anything, so I've cleaned them up.
