This started as a customer request, where the customer wanted to
store a file in the ROM file system with a bunch of command line
parameters in it, and then use the @file syntax to run that file
and setup the interpreter. In essence a 'canned' setup stored in
the ROM file system.
That didn't work, at all, because of a dichotomy in the logic of
argument processing. The code used 'lib_file_open' in order to find
the file using the search path which, on Ghostscript, includes all
the iodevices, Rom file system, RAM file system etc.
That function returns a stream which the calling function 'lib_fopen'
would then reach inside and pull out the pointer to the underlying
gp__file *, and return, because the argument processing was written
to use a gp_file *, not a stream *.
But.... For the ROM file system, what we store in the 'file' member
of the stream is not a gp_file *, its a 'node' *. Trying to use that
as a gp_file * rapidly leads to a seg fault.
So this commit reworks the argument processing to use a stream *
instead of a gp_file *. In reality there is no real difference to the
logic we simply use a different call. There are a lot of fiddly
references to change unfortunately.
There are some consequences; we need to pass stream * around instead of
gp_file *, and in particular the 'encoding' functions, which are
OS-specific need to use a stream *. This isn't a problem for the
interpreters and graphics library, but mkromfs *also* uses those
OS-specific files, and it does not have the stream library available.
Rather than trying to include it, we note that we don't actually need
to use these functions for mkromfs and we do the same hackery as for
other missing functionality; we define a stub function that does nothing
but will permit the compile to complete.

Thanks to Peter Cherepanov for this patch (and his patience in having
it accepted). Tested with VS 2005, 2008, 2015 and 2019.
WIth this change Windows operates like linux. Note that usertime always
returns 0 the first time it is called (refer to commit cc156631). This
is a bit confusing, but is intentional.

(squash of commits from filesec branch)
Most of this commit is donkeywork conversions of calls from
FILE * -> gp_file *, fwrite -> gp_fwrite etc. Pretty much every
device is touched, along with the clist and parsing code.
The more interesting changes are within gp.h (where the actual
new API is defined), gpmisc.c (where the basic implementations
live), and the platform specific levels (gp_mswin.c, gp_unifs.c
etc where the platform specific implementations have been
tweaked/renamed).
File opening path validation
All file opening routines now call a central routine for
path validation.
This then consults new entries in gs_lib_ctx to see if validation
is enabled or not. If so, it validates the paths by seeing if
they match.
Simple C level functions for adding/removing/clearing paths, exposed
through the gsapi level.
Add 2 postscript operators for path control.
<name> <string> .addcontrolpath -
Add the given <string> (path) to the list of paths for
controlset <name>, where <name> can be:
/PermitFileReading
/PermitFileWriting
/PermitFileControl
(Anything else -> rangecheck)
- .activatepathcontrol -
Enable path control. At this point PS cannot make any
more changes, and all file access is checked.

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.

Also fix the Windows go_get_realtime() function so that it returns
the same values as the other OS's
The change in time_.h is to prevent the definition of timeval if we
have already included windows.h (_WINDOWS_ is defined) as this also
defines timeval (actually in winsock.h, claims to be copied from a BSD
header).
|

|
|

Always include windows_.h first, wherever we include it.
This gets the windows definition of 'bool' in, and we can then
override it with our own.

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.
