Previously I was calling gs_free_object and relying on the rc
count being zero. Now I properly set up the ref counting, and
call rc_decrement.
|
| |
|
|
|
| |
This means we can track the history of ref count changes for blocks
within Memento.

Introduce a PRI_INTPTR and use that to consistently display
pointers. We avoid using %p, as that displays inconsistently
between platforms. Sometimes it does 0x%x, sometimes just %x.

Run a release build on a linux machine to make arch.h etc. Then
run toolbin/headercompile.pl to test compiling each headerfile
by itself.
Resolve all the missing #includes, add missing repeated include
guards and copyright statements.
Also, update all the header dependencies in the makefiles.
It is possible that the object dependencies in the makefiles can be
simplified now, but that's a task for another day.

Rearrange order of macro so that the memory is freed even if the call to
rc_alloc_struct_1 fails.

In a debug build, to facilitate logging/debugging, the rc_ajust() macro
calls a function to trace the reference count changes. The client name (cname)
parameter should be declared const to avoid a compiler warning.

The change to ref_count of profiles needs to be protected by a lock if
the profile ref_count could be changed by another thread. Also when
decrementing the ref_count to 0, we cannot free the lock until after
the profile has been unlocked.
New routine gsicc_adjust_profile_rc replaces old (not threadsafe) function
gsicc_profile_reference.
Also add tracing "cname" to the RC_ADJUST_ macro to aid in debugging
with -Z^ debug flag.
Testing had revealed race conditions which are now fixed (eliminate use
of semaphores).
This also changes the gsicc_lcms2art.c interface functions to keep a
list of transforms configured to have differing buffer formats that
include alpha, planar IN/OUT, big_endian IN/OUT, bytes_per_component
IN/OUT which are cloned as needed by threads.
Change gscms_is_threadsafe to return "true" in gsicc_lcms2art.c
TBD: If a link fails to build a thread may hang waiting for the link
profile to become valid if it was not the thread that was building it.
Not a new condition, but exposed when gscms_is_threadsafe returns true.
TBD: Fix error handling / clean-up when links fail to build. Also not
new, but is needed to prevent leaks, and possibly hang conditions.

Also update copyright dates.
Remove gs_cmdl.ps as we no longer use it, and remove its entry from
psfiles.htm.
Remove xfonts.htm as this feature (xfont support) is long, long gone.

Change how gstate initialisation is done:
Previously we relied on the imager state being a subset of the gstate (thus
assigning an imager state to a graphics state over wrote to the entries
common to both, and didn't overwrite any already set graphics state specific
entries).
Making the imager and graphics states the same means that approach doesn't work,
so this changes it to initialise the entries individually.
Renames gsistate.c->gsgstate.c and gxistate.h->gxgstate.h
Cleanup and fix the gs_state gc stuff.
Uses different check for pre/post clist pdf14 device
Previously, the code used "is_gstate" in the imager/graphics state object
to determine if the code was being called pre or post clist (post clist would
only ever have had an imager_state so is_gstate = false).
With no imager state any more, that test would no longer work (and I am dubious
about whether it was really safe, anyway). Other places check for the presence
of a clist reader device in the pdf14 device structure - so use that here
too.
Adds initial (NULL) value for show_gstate pointer in gs_state.
Removes the now pointless macro for the contents of the graphics state
Changes function names that had "imager" to use "gstate"
Removes the redundant 'is_state' flag
Cleans up gs_(g)state_putdeviceparams():
Previously we had to similar routines: one took a graphics state, and used the
device from the graphics state, the other took an imager state and the device
as an explicit parameter.
With the removal of the imager state, "merge" those two functions
Replaces gs_state with gs_gstate
It makes for less confusion as it really is a g(raphics)state

Squashed into one commit (see branch for details of the evolution of the
branch).
This brings gpcl6 and gxps into the Ghostscript build system, and a shared
set of graphics library object files for all the interpreters.
Also, brings the same configuration options to the pcl and xps products as we
have for Ghostscript.
