Non HTTP + tests have been salvaged to always run in this script. + + * "git clean -d" used to clean directories that has ignored files, + even though the command should not lose ignored ones without "-x". + "git status --ignored" did not list ignored and untracked files + without "-uall". These have been corrected. + + * The timestamp of the index file is now taken after the file is + closed, to help Windows, on which a stale timestamp is reported by + fstat() on a file that is opened for writing and data was written + but not yet closed. + + * "git pull --rebase --autostash" didn't auto-stash when the local history + fast-forwards to the upstream. + +Also contains various documentation updates and code clean-ups. diff --git a/Documentation/git-pull.txt b/Documentation/git-pull.txt index 942af8e0f7..e414185f5a 100644 --- a/Documentation/git-pull.txt +++ b/Documentation/git-pull.txt @@ -159,15 +159,15 @@ present while on branch `<name>`, that value is used instead of In order to determine what URL to use to fetch from, the value of the configuration `remote.<origin>.url` is consulted -and if there is not any such variable, the value on `URL: ` line -in `$GIT_DIR/remotes/<origin>` file is used. +and if there is not any such variable, the value on the `URL:` line +in `$GIT_DIR/remotes/<origin>` is used.
