------------ From: /u2/davis/ Thu 16:47:49 01-Aug-85 Package: images Title: new images tasks The tasks ROTATE, IMLINTRAN and GEODISTRAN have been added to the images package. ROTATE rotates and shifts an image. IMLINTRAN will rotate, rescale and shift an an image. GEODISTRAN corrects an image for geometric distortion. ------------ From: /u2/davis/ Fri 18:14:12 02-Aug-85 Package: images Title: new images task A new task GEOMAP has been added to the images package. GEOMAP calculates the spatial transformation required to map one image onto another. ------------ From: /u2/davis/ Tue 08:27:09 06-Aug-85 Package: images Title: imshift bug Imshift was shifting incorrectly when an integral pixel shift in x and a fractional pixel shift in y was requested. The actual x shift was xshift + 1. The bug has been fixed and imshift will now work correctly for any combination of fractional and integral pixel shifts ------------ From: /u2/davis/ Fri 10:53:18 09-Aug-85 Package: dataio Title: reblock mod The task REBLOCK has been modified so that it will trim as well as pad logical records. ------------ From: /u2/davis/ Fri 15:05:31 09-Aug-85 Package: math Title: math documentation The documentation for the 2D interpolation routines has been added to the math package. ------------ From: /u2/davis/ Mon 15:55:45 12-Aug-85 Package: math Title: gsurfit package A set of routine for fitting surfaces and accompanying documentation have been installed in the math package. ------------ From: /u2/davis/ Tue 08:26:19 01-Oct-85 Package: images Title: fmedian, median Two median filtering tasks have been added to the images package. Fmedain is a fast median processing routine which utilises the image histogram to calculate the median at each window position. Fmedian is best suited to integer data. Median is a more general routine which uses a sorting technique but takes longer to execute. ------------ From: /u2/davis/ Thu 17:06:15 03-Oct-85 Package: images Title: minmax bug Minmax was not calculating the minimum correctly for integer images. ------------ From: /u2/davis/ Mon 10:51:05 21-Oct-85 Package: images Title: imsurfit bug An error in pixel rejections cycle of IMSURFIT corrected. The routine make_ranges was not successfully converting a sorted list of rejected pixels into a list of ranges in all cases. ------------ From: /u2/hammond/iraf/ Tue 16:45:33 29-Oct-85 Package: dataio Title: New task installed Task rtextimage, which converts text files to IRAF images, has been installed in the dataio package. ------------ From: tody Thu Nov 7 22:25:20 MST 1985 Package: cl Title: foreign tasks in the CL A new type of task called a "foreign task" has been added to the CL. This facility was added primarily to provide an improved interface for the bootstrap utilities XC and MKLIB, but may be used to access any host system utility to enhance one's personal IRAF environment. The foreign task facility is a type of OS escape, hence should not be used in mainline software. One ore more foreign tasks may be defined with the TASK statement by setting the "physical task name" to the special value "$foreign", e.g., task $xc, $mklib, $make = "$foreign" A foreign task, once defined, may be called by name like any other IRAF task, without the overhead of processing a script task containing an OS escape. The argument list of a foreign task is parsed exactly like that of any other task, allowing the string value of a parameter to be generated by any CL expression. Full i/o redirection is supported. A foreign task is run by passing a string command to the host system with ZOSCMD. The command is built up by concatenating the task name with the values of the argument strings in the order in which they appear on the command line, inserting a blank between each string argument. Foreign tasks may have parameter files, but normally there will be no parameter file and the arguments will be given in the same syntax one would use when operating outside the CL. This provides a more direct interface and eliminates needless restrictions and the need to learn a second syntax for the same command (e.g., xc and xcompile). An additional advantage of the foreign task interface is that i/o redirection is implemented without the temporary files used for !cmd type OS escapes. In other words, given a command such as xc -cO file1.x file2.x >& spool & output will be written directly into the spool file during task execution, rather than copied to the spool file after task execution. This prevents stdout and stderr from being separated and permits use of TAIL during execution to see how things are going (at least on UNIX). Since flags beginning with - are so common in UNIX, "lexmodes" has been enhanced to treat arguments beginning with a minus (or plus) sign as string constants. The softools tasks XC, MKLIB, and MAKE have been redefined as foreign tasks and the new version of the CL which supports foreign tasks has been installed. MAKE will probably be deleted from softools in the near future. ------------------------------------------------------------------------------ sys/clio/zfiocl.x In zardps(), in the first call to zardpr, changed the third argument to SZ_NUMSTR * SZB_CHAR; would cause XFER failure on AOS. (11/8 dct) pkg/cl/unop.c pkg/cl/gram.c pkg/cl/operand.h Added a new CL intrinsic function osfn(). This function takes a virtual filename as input and returns a host system filename as output. (11/9 dct) sys/os/zfiotx.c [UNIX] Modified terminal (text file) driver to mask parity bit when reading from the terminal in raw mode. (11/10 dct) pkg/cl/* Merged revisions from the VMS version of the cl into the unix sources. These consisted mostly of VMS/C compiler workarounds, some allocate stuff (deactivated in unix/iraf currently), and other minor changes. (11/11 dct) sys/fio/ffault.x When faulting in the FIO buffer on a write-only file, not at EOF, the ITOP pointer would be set to the start of the buffer rather than to the end, as it is if the buffer is actually filled from the file. When the buffer is later flushed the amount of data written would be less than a full buffer if the full buffer had not been written into. Modified to set ITOP to BP+BUFSIZE when filling the buffer on a write only random access file, not at EOF. (11/13) sys/gio/stdgraph/stgencode.x Changed the code for \ch in compile mode to push the escaped character rather than output it. Reversed the arguments to ; (goto) to match the order described in the documentation. (11/14) sys/gio/stdgraph/tshowcap.x Installed a new version which supports boolean capabilities, scan cursor, etc. (11/14) sys/libc/cmain.c Deleted this file from the library, since it causes linker problems and it no longer used (cl.x defined ONENTRY and calls c_main directly). (11/15) pkg/cl/task.h pkg/cl/builtin.c Added user definable OSCMD prefix strings to the foreign task interface. This removes the restriction that the host task name be equivalent to the logical task name, e.g., permitting calling the host task with a full pathname, with a different name, with switches, etc. (11/15) pkg/cl/builtin.c pkg/cl/task.h Generalized the foreign task interface to permit user specification of the foreign command prefix string. In the case task $ltname = $foreign the foreign command prefix string defaults to "ltname", and multiple foreign tasks may be declared in a single statement. In the case task $ltname = $prefix the command sent to the host system will begin with the given prefix string, which may be different from the ltask name and which may contain whitespace. For example, task $who = "$show users" will perform the UNIX "who" function on a VMS system. On a UNIX system, task $renice = "$/etc/renice" would make the renice task available as a CL task, even though the /etc directory is not normally in one's search path. (11/16) sys/os/zwmsec.c sys/os/Makelib lib/libc/knames.h KERNEL CHANGE ------------------------------------------------------------------------------- New module ZWMSEC added to package OS. The new kernel operator suspends process execution for the indicated number of milliseconds. (11/18) ------------------------------------------------------------------------------- sys/fmtio/printf.h Changed the size of the internal printf buffer from SZ_LINE to 1024 to reduce the possibility of truncation when printing strings. (11/27) sys/fmtio/Makelib Several files which included printf.h did not list it as a dependency in the Makelib file. (11/27) sys/etc/main.x Did not permit parameters with upper case names. (11/27) pkg/cl/exec.c Simplified the mk_startupmsg procedure slightly, while looking for a problem that turned out to be elsewhere. (11/27) pkg/cl/task.h Two of the T_XXX task bit flags had the same value. (11/27) pkg/cl/bkg.c When a new CL is installed while someone is using the old one, the core image bkgfile produced when a bkg job is submitted by the old CL may not be usable by the new CL. The CL checks for this when reading the bkgfile, but error recursion was occurring due to the call to EPRINTF to report the error. This was replaced by a call to fprintf(stderr since EPRINTF is higher level (it requires a stacked task descriptor which is not there until the bkg file has been read) and cannot be used during process startup.
