Hi, all

I find org-babel-load-file not work for my emacs-starter-kit  org file.
After some traces, I find that

   (org-babel-merge-params nil nil nil)

returns:

   ((:comments . "") (:shebang . "") (:cache . "") (:padline . "") (:noweb
. "") (:tangle . "") (:exports . "") (:results . ""))

which will override my default (:tangle "yes") value in
org-babel-default-header-args
and org-babel-load-file simply don't tangle source blocks without ":tangle
yes".

Below is the patch that solves this problem.

Recently I also noticed a regression of org-babel-load-file that is
resolved with your patch. Thank you for saving me of one of my TODOs.

This patch doesn't fix the actual cause of this bug.  The problem stems
from commit 693dda67 [1], and I've just pushed up a fix in commit
a79fd4be [2].

Thanks to both of your for raising this issue.

         ob-core: allow language specific header arguments in properties

         * lisp/ob-core.el (org-babel-insert-header-arg,
           org-babel-parse-src-block-match): Replace `if' with empty else part
           by `when' for readability.  (org-babel-params-from-properties):
           Inquire for language specific and default header properties.
           Language specific header properties take precedence over default
           header properties and old-style header property specifications.

         This allows for header arguments to be specified as
         properties (including inheritance).

         #+PROPERTY: header-args :cache "no"
         #+PROPERTY: header-args:R :session "*R-property*"

         :PROPERTIES:
         :header-args:   :cache "yes"
         :header-args:R: :session "*R-drawer*"
         :END:

[2]  commit a79fd4be2863a300c88218b40b1adca23d9e1eb8

         fix babel merge params bug from commit 693dda67

           The `org-babel-params-from-properties' command was calling
           `org-babel-merge-params', the output of which was then being fed back
           to another call to `org-babel-merge-params'.  The merge params
           function is not designed to allow this form of recursive calling, and
           as a result many variables were being set to empty values.

           The first noticed side effect of this bug was the breakage of the
           org-babel-load-file command, which relies on default header
           arguments (namely :tangle), which were overwritten by the bug above.

           The fix involved having the `org-babel-params-from-properties'
           function return a list of alists, which may then all be handed to the
           top-level merge-params call.

         * lisp/ob-core.el (org-babel-params-from-properties): Now returns a list
           of alists and does *not* call `org-babel-merge-params'.
           (org-babel-parse-src-block-match): Handle new list of lists output of
           `org-babel-params-from-properties'.
           (org-babel-parse-inline-src-block-match): Handle new list of lists
           output of `org-babel-params-from-properties'.
         * lisp/ob-exp.el (org-babel-exp-src-block): Handle new list of lists
           output of `org-babel-params-from-properties'.
           (org-babel-exp-non-block-elements): Handle new list of lists output of
           `org-babel-params-from-properties'.
         * lisp/ob-lob.el (org-babel-lob-execute): Handle new list of lists
           output of `org-babel-params-from-properties'.
