What does it take to fix this before it's faster to do a Teamware bringover of the j2se repository than to push a couple of files to hg.ojn? -- Jon > real 10m7.790s > user 0m0.192s > sys 0m0.048s Jonathan Gibbons wrote: > Any chance of that upgrade happening?

In-Reply-To: maurizio.cimadamore@sun.com; Tue, 11 Aug 2009 18:30:32 BST; <4A81AAB8.5060203@sun.com> Message-ID: <20090911223604.4D095487@eggemoggin.niobe.net> I've written a script to reap old changegroup snapshots, and removed all snapshots older than 14 days (excepting the latest snapshot of each repo filesystem). A push to hg.ojn now takes about 20 seconds. I'll set up a cron job to reap snapshots on a regular basis. Further improvement will be possible after we migrate to the new datacenter, but for now 20 seconds << 5 minutes. - Mark From Kelly.Ohair at Sun.COM Wed Sep 23 10:48:58 2009 From: Kelly.Ohair at Sun.COM (Kelly O'Hair) Date: Wed, 23 Sep 2009 10:48:58 -0700 Subject: Patch for JTreg test java/net/MulticastSocket/SetOutgoingIf.java In-Reply-To: <17c6771e0909230746j6767fbe3i787aa31ac4a076de@mail.gmail.com> References: <4AB9F725.5000704@redhat.com> <4AB9FFFD.2050303@sun.com> <4ABA1276.6090506@sun.com> <4ABA20BD.4030305@redhat.com> <17c6771e0909230635s155080c6id7a02de2ba8bde12@mail.gmail.com> <4ABA3283.4090209@redhat.com> <17c6771e0909230746j6767fbe3i787aa31ac4a076de@mail.gmail.com> Message-ID: <4ABA5F8A.8080000@sun.com> Andrew John Hughes wrote: > 2009/9/23 Andrew Haley : >> Andrew John Hughes wrote: >>> 2009/9/23 Andrew Haley : >>>> Christopher Hegarty -Sun Microsystems Ireland wrote: >>>>> [cc'ing net-dev] >>>>> >>>>> I see you have push access, so if you make the appropriate changes >>>>> (mentioned above) I can review the webrev and you can use the above bug >>>>> number and description to push the changeset. >>>> Please make sure you tell Pavel which forest to push to.

I will try and see if I can do some updating to this repositories page. If there are other problems with this page, let me know I'll try and include the changes people tell me about, within reason of course.. ;^) -kto
