[Emacs-diffs] master updated (fc0fd24 -> 2412a1f)

[Eli Zaretskii]

eliz pushed a change to branch master.

      from  fc0fd24   Fix further problems with quoted file names in Tramp
      adds  68b3248   This introduces a thread-state object and moves various C 
globals there.  It also introduces #defines for these globals to avoid a 
monster patch.
      adds  2d525b7   This parameterizes the GC a bit to make it thread-ready.
      adds  14b3dc5   This introduces the low-level system threading support.  
It also adds the global lock.  The low-level support is a bit over-eager, in 
that even at the end of the present series, it will not all be used.  I think 
thiat is ok since I plan to use it all eventually -- in particular for the 
emacs lisp mutex implementation.
      adds  e160922   This introduces some new functions to handle the specpdl. 
 The basic idea is that when a thread loses the interpreter lock, it will 
unbind the bindings it has put in place.  Then when a thread acquires the lock, 
it will restore its bindings.
      adds  60a9d2a   This turns thread_state into a pseudovector and updates 
various bits of Emacs to cope.
      adds  1dcacbc   This adds most of the thread features visible to emacs 
lisp.
      adds  51100bb   This supplies the mutex implementation for Emacs Lisp.
      adds  fc196ac   This adds some tests of the threading code.
      adds  8d3566c   This adds names to mutexes.  This seemed like a nice 
debugging extension.
      adds  dbb33d4   This adds thread-blocker, a function to examine what a 
thread is blocked on.  I thought this would be another nice debugging addition.
      adds  0ccc5d8   fix a latent bug in process.c
      adds  aa14ccd1  Prepare process.c for threads by not having global select 
masks. The next step is to make it so selects can choose fds by thread.
