Daniel Hahler 481cd8f843 minor: doc: fix typo in buffer_init 2015-07-28 19:31:51 +02:00
Uli Schlachter c945492176 Keep client order across restarts
This saves the order of clients in a property called AWESOME_CLIENT_ORDER on the
root window during shutdown. During startup, after managing all existing
windows, we force the client list into the order described by this property
(overwriting any changes that Lua possibly did).

This code should safely handle cases where the property doesn't contain all
existing clients or contains a client which doesn't exist anymore.

Uli Schlachter 1408e8b952 Unset object's metatable in __gc
Run the following code:

  do
      local d
      local f = function() d.visible = true end
      if _VERSION >= "Lua 5.2" then
          setmetatable({}, { __gc = f })
      else
          getmetatable(newproxy(true)).__gc = f
      end
      d = drawin({})
  end
  collectgarbage("collect")

Awesome will segfault.

The reason for this is that after the above code ran, all variables in it are
unreferenced and will be garbage-collected at the next sweep phase. Lua runs
garbage collectors in the inverse order that their corresponding objects were
"marked" which means for the above code that the drawin's garbage collector will
run before function f runs. So the code will access the drawin after its
destructor already ran. Obviously, awesome's C code does not expect nor
correctly deal with this situation and was dereferencing a NULL pointer.

To fix this, this commit "unsets" the metatable of a userdata object when it is
being garbage collected. Since the type of a userdata is inferred via its
metatable, the object will no longer be accepted by luaA_toudata().

For the above code this will result in an unhelpful error message saying that
something tried to index a userdata, but userdata cannot be indexed. At least we
no longer crash and the traceback of the error will hopefully point at some __gc
metamethod which should be enough of a hint to figure out the problem.

Uli Schlachter f5610fa920 objects: Add .valid property (Fixes #110)
This property is especially useful for client objects which are unusable after
unmanage. "Unusuable" here means that pretty much everything you do with the
client object results in a lua error.

Syntax is c.valid.

Daniel Hahler f562b4a64b luaA_object_emit_signal: check for valid object
By the time a signal gets emitted the object might be invalid already,
e.g. when it is very short-lived and unmanaged by the time the delayed
call to emit_signal is being invoked.

Uli Schlachter 381d840a82 Use $PATH when starting $SHELL
If $SHELL is set to "bash", previously awesome failed to restart itself, because
it could not find "bash". This commit makes awesome use execlp() instead of
execl() which means that $PATH is searched if the started command does not
contain a slash and this problem is fixed.

Uli Schlachter aaa771f887 Switch from libXcursor to libxcb-cursor
Thanks to Michael Stapelberg, there is now a xcb-only port of libXcursor which
does everything we need. This patch switches awesome over to that new library.

Since the only reason for using XOpenDisplay() instead of xcb_connect() was so
that we can use libXcursor, we can get back to that older state again. This
means that this effectively reverts the following commits:

531f8b415c "Added initial support for Xlib cursor themes"
77243cd09a "Add x11-xcb to the pkg-config checks"
779d43fc46 "Don't let Xlib own the event queue"

Arvydas Sidorenko c491cd034c common/util.h: dodgy non-__GNUC__ p_delete
I assume nobody have tried to compile Awesome with GNU uncompatible
compiler for ages and thus non-__GNUC__ p_delete version got
overlooked for quite some time.
First of all, a problem I see is that it assigns void** to a variable
of type void* and then dereferences the same void* variable.
None of the compilers I am aware of will let you go through this
without an error.
And second of all, lets have one portable p_delete.

This function can be called from unprotected contexts. Calling luaL_error() in
this case results in a call to luaA_panic() and awesome dies.

The only real change here is that this now calls warn() instead of luaL_error().
