[ https://issues.jboss.org/browse/JBIDE-13175?page=com.atlassian.jira.plugi... ] Andre Dietisheim edited comment on JBIDE-13175 at 1/28/13 8:47 AM: ------------------------------------------------------------------- after reading a lot of code and a lot of git manuals and even testing a lot, I'm completely sure that there's no way to do a diff btw. an local and a remote without fetching the remote first. To prove it, do the following: * git clone an openshift repo to your local machine. You'll get a local branch with 2 branches: {code} [adietish@adietish-thinkpad aa]$ git branch -a * master remotes/origin/master {code} * You'll be able to do a diff btw. those 2: {code} [adietish@adietish-thinkpad aa]$ git diff --shortstat master origin/master 1 files changed, 0 insertions(+), 4 deletions(-) {code} * Now add the origin as *openshift* to your repo: {code} [adietish@adietish-thinkpad aa]$ git remote -v origin ssh://31d6dc5619f24750b09941de420c133e@aa-myops.rhcloud.com/~/git/aa.git/ (fetch) origin ssh://31d6dc5619f24750b09941de420c133e@aa-myops.rhcloud.com/~/git/aa.git/ (push) [adietish@adietish-thinkpad aa]$ git remote add openshift ssh://31d6dc5619f24750b09941de420c133e@aa-myops.rhcloud.com/~/git/aa.git/ {code} * and try to diff, it wont work: {code} [adietish@adietish-thinkpad aa]$ git diff --shortstat master openshift/master fatal: ambiguous argument 'openshift/master': unknown revision or path not in the working tree. Use '--' to separate paths from revisions {code} * you have to first fetch (and get another remote tracking branch) so that the diff works: {code} [adietish@adietish-thinkpad aa]$ git fetch openshift * [new branch] master -> openshift/master [adietish@adietish-thinkpad aa]$ git branch -a * master remotes/openshift/master remotes/origin/master [adietish@adietish-thinkpad aa]$ git diff master --shortstat openshift/master 1 files changed, 0 insertions(+), 4 deletions(-) {code} It's important to note that the remote tracking branch (and thus the diff) will only get created if the remote is added with a fetch-spec {code} [remote "openshift"] url = ssh://31d6dc5619f24750b09941de420c133e@aa-myops.rhcloud.com/~/git/aa.git fetch = +refs/heads/*:refs/remotes/openshift/*. {code} If the remote is added without a fetch-spec, then fetching does not help.
