In these sorts of cases your Git client can't\naccurately determine what the server has and does not have, so it errs\non the conservative side and sends a lot more than it probably needed\nto.\n"},{"id":"189631","messageId":"15053.1334758946@plover.com","threadId":"30264","inReplyTo":"CAJo=hJuGHymJtZL14mAq0gBZE+za5URoon=rMzPA=tTQC14ftQ@mail.gmail.com","subject":"Re: git-push sent too many objects","fromName":"Mark Jason Dominus","fromEmail":"mjd@plover.com","sentAt":"2012-04-18T14:22:26Z","receivedAt":"2012-04-18T14:22:26Z","isPatch":false,"sender":{"key":"mjd@plover.com","avatar":"https://gravatar.com/avatar/a874d23a21a54fc9c5e9d91614219a150bd89c90c1cb0ef970e689f5b88c098b?d=mp&s=160"},"body":"Shawn Pearce:\n> On Tue, Apr 17, 2012 at 09:53, Mark Jason Dominus wrote:\n> > What happened here? =A0Why did git-push send 1,315 objects instead of 5?\n> \n> Is it possible someone else modified the repository at the same time?\n\nIt is extremely unlikely.
