Bug 696246: devijs account for device sublassing.
|
|
|
|
The IJS device wasn't coping with the possibility it had been subclassed.

Bug 696246: patch the memory manager fields for sublassed devices.
|
|
|
|
When we subclass a device, we were patching the "visible" type field - that is,
|
|
the one referenced directly in the device structure. We were not patching
|
|
the type information in the memory object header so, in particular, the
|
|
garbage collector could end up calling the wrong methods for the subclassed
|
|
device.
|
|
|
|
No cluster differences.

Subject: [PATCH] Guard against NULL 'base' for non-clist devices
|
|
|
|
Bug #696246 "Ghostscript 9.18 with -dFirstPage/-dLastPage fails for ijs and some x11 devices"
|
|
|
|
This is actually for the plib device. This device is currently (this will
|
|
change in the next commit) set to BandingAuto, despite the fact that the
|
|
device only works in banding mode.
|
|
|
|
This can lead to use arriving in gdev_mem_open_scan_lines with all of
|
|
mdev->bitmap_memory, mdev->line_pointers_memory and mdev->base being set to
|
|
NULL. The code didn't check and assumed that mdev->base was valid, which
|
|
led to a later seg fault.
|
|
|
|
Here we just check to make sure it isn't NULL and return an error if it is.
|
|
This doesn't prevent the possibility of garbage uninitialised values, but
|
|
there's not much we can do to check that at this stage, devices are supposed
|
|
to be initialised to 0 so this 'shouldn't' happen.
|
|
|
|
No differences expected.

Subject: [PATCH] Ensure plib devices always use the clist
|
|
|
|
Bug #696246 "Ghostscript 9.18 with -dFirstPage/-dLastPage fails for ijs and some x11 devices"
|
|
|
|
the plib* class of devices only work if clist is present, but previously
|
|
they left the banding_type set to 'auto', which meant that under some
|
|
conditions we did not use the clist, leading to a seg fault.
|
|
|
|
This commit simply forces banding_type to be 'BandingAlways'.
|
|
|
|
No differences expected.

Subject: [PATCH] prevent rinkj device crash when misconfigured (no SetupFile)
|
|
|
|
Bug #696246 "Ghostscript 9.18 with -dFirstPage/-dLastPage fails for ijs and some x11 devices"
|
|
|
|
The rinkj device requires a SetupFile to be given as a device parameter,
|
|
however it doesn't actually check to see if one is given, and just tries
|
|
to open the filename, with a predictable crash when none is given.
|
|
|
|
Here we check the filename and attempt to ensure it is both present and
|
|
minimally valid.
|
|
|
|
No differences expected.
