Subject: [PATCH 1/4] Have gs_cet.ps run from gs_init.ps
|
||
|
|
||
|
Previously gs_cet.ps was run on the command line, to set up the interpreter
|
||
|
state so our output more closely matches the example output for the QL CET
|
||
|
tests.
|
||
|
|
||
|
Allow a -dCETMODE command line switch, which will cause gs_init.ps to run the
|
||
|
file directly.
|
||
|
|
||
|
This works better for gpdl as it means the changes are made in the intial
|
||
|
interpreter state, rather than after initialisation is complete.
|
||
|
|
||
|
This also means adding a definition of the default procedure for black
|
||
|
generation and under color removal (rather it being defined in-line in
|
||
|
.setdefaultbgucr
|
||
|
|
||
|
Also, add a check so gs_cet.ps only runs once - if we try to run it a second
|
||
|
time, we'll just skip over the file, flushing through to the end.

Subject: [PATCH 2/4] Undef /odef in gs_init.ps
|
||
|
|
||
|
Made a new temporary utility function in gs_cet.ps (.odef) to use instead
|
||
|
of /odef. This makes it fine to undef odef with all the other operators in
|
||
|
gs_init.ps
|
||
|
|
||
|
This punts the bigger question of what to do with .makeoperator, but it
|
||
|
doesn't make the situation any worse than it already was.

Subject: [PATCH 3/4] Fix bug 700585: Restrict superexec and remove it from
|
||
|
internals and gs_cet.ps
|
||
|
|
||
|
Also while changing things, restructure the CETMODE so that it will
|
||
|
work with -dSAFER. The gs_cet.ps is now run when we are still at save
|
||
|
level 0 with systemdict writeable. Allows us to undefine .makeoperator
|
||
|
and .setCPSImode internal operators after CETMODE is handled.
|
||
|
|
||
|
Change previous uses of superexec to using .forceput (with the usual
|
||
|
.bind executeonly to hide it).

Subject: [PATCH 4/4] Bug 700585: Obliterate "superexec". We don't need it, nor
|
||
|
do any known apps.
|
||
|
|
||
|
We were under the impression that the Windows driver 'PScript5.dll' used
|
||
|
superexec, but after testing with our extensive suite of PostScript file,
|
||
|
and analysis of the PScript5 "Adobe CoolType ProcSet, it does not appear
|
||
|
that this operator is needed anymore. Get rid of superexec and all of the
|
||
|
references to it, since it is a potential security hole.
