问题 Why is it bad to check in lines with trailing whitespace to your source control? What kinds of problems could that cause? 回答1: False differences, basically. It's helpful if diffs only show "real" changes. Some diff programs will ignore whitespace, but it would be better just to avoid the dummy change in the first place. Of course, it also doesn't help if it makes the line wrap on a colleague's machine. 回答2: It's like painting your walls, but not finishing the edges off properly, and going

问题 My git version is Git-1.9.4-preview20140611 Earlier, I cloned an empty git origin repository. The repository cloned but with following message warning: You appear to have cloned an empty repository. Checking connectivity... done. Next, copied a .gitIgnore file which was in another project's master Git repository and committed it to the local master. This file has been used by us for many times before. This seems fine. We have a standardized .gitIgnore file for all our projects. This was

问题 I'd like to follow the development of JDK8, but what I see in the repo is strange at best: 6 days ago katleman Added tag jdk8-b60 for changeset e07f499b9dcc default tip changeset | manifest 7 days ago katleman Merge jdk8-b60 changeset | manifest Most changes look like "Added tag jdk8-b60 for changeset XXX" or "Merge XXX", there are a few entries looking like actual code changes, but no link to leads to code. Actually no single click brought me to anything marginally useful. I know nothing

问题 In Git SCM I'm using the following command to check whether a specific revision is present on some remote: git fetch <remote> <revision> -q --dry-run If the exit code of the command is zero that means the revision is present on the remote. For Mercurial I tried the following command: hg pull <remote> -r <revision> -q It works but the problem is that it actually pulls the revision if present on the remote, but not locally. Is there an equivalent of the --dry-run option for Git, or some other

问题 I am trying to set git branch upstream but getting below warning. Command git checkout master git branch --set-upstream-to master warning: Not setting branch master as its own upstream. How can I solve it? Does that mean it already being tracing correct remote branch master ? 回答1: That should be: git branch --set-upstream-to origin/master But if origin/master is there, the checkout should have tracked it already. If <branch> is not found but there does exist a tracking branch in exactly one

问题 I am looking for a way to put an end to "holy wars" about "the only right code formatting for all people". Currently, most companies have its own code-style (expressed as, for example, .clang-format ), but obviously people have different mindsets/tastes/views on how the ideal formatting should look like. My idea is based upon the fact that it is only important to push my code in central repo in the format of a company, while nobody prevents me from having and working with code that is
