+Subject: [PATCH] config: quote values containing CR character
|
|
|
+
|
|
|
+When reading the config, values that contain a trailing CRLF are
|
|
|
+stripped. If the value itself has a trailing CR, the normal LF that
|
|
|
+follows results in the CR being unintentionally stripped. This may lead
|
|
|
+to unintended behavior due to the config value written being different
|
|
|
+when it gets read.
|
|
|
+
|
|
|
+One such issue involves a repository with a submodule path containing a
|
|
|
+trailing CR. When the submodule gets initialized, the submodule is
|
|
|
+cloned without being checked out and has "core.worktree" set to the
|
|
|
+submodule path. The git-checkout(1) that gets spawned later reads the
|
|
|
+"core.worktree" config value, but without the trailing CR, and
|
|
|
+consequently attempts to checkout to a different path than intended.
|
|
|
+
|
|
|
+If the repository contains a matching path that is a symlink, it is
|
|
|
+possible for the submodule repository to be checked out in arbitrary
|
|
|
+locations. This is extra bad when the symlink points to the submodule
|
|
|
+hooks directory and the submodule repository contains an executable
|
|
|
+"post-checkout" hook. Once the submodule repository checkout completes,
|
|
|
+the "post-checkout" hook immediately executes.
|
|
|
+
|
|
|
+To prevent mismatched config state due to misinterpreting a trailing CR,
|
|
|
+wrap config values containing CR in double quotes when writing the
|
|
|
+entry. This ensures a trailing CR is always separated for an LF and thus
|
|
|
+prevented from getting stripped.
|
|
|
+
|
|
|
+Note that this problem cannot be addressed by just quoting each CR with
|
|
|
+"\r". The reading side of the config interprets only a few backslash
|
|
|
+escapes, and "\r" is not among them. This fix is sufficient though
|
|
|
+because it only affects the CR at the end of a line and any literal CR
|
|
|
+in the interior is already preserved.
