(6/12) + +pkg/images/geometry/t_geotran.x +pkg/images/geometry/geotran.x +pkg/images/geometry/geotimtran.x + Fixed a bug in the buffering of the x and y coordinate surface + interpolants which can cause a memory corruption error if, the + nxsample or nysample parameters are > 1, and the nxblock or nyblock + parameters are less than the x and y dimensions of the input image. + Took the opportunity to clean up the code.

Cvepower + computes the errors in the power series coefficients equivalent + to the fitted Legendre and Chebyshev coefficients. Cvepower is + available in both real and double precision versions.

Removed the 64X64 kernel size limit + in the median and mode tasks. Replaced the common blocks with + structures and .h files.

(6/20/95, LED) + +doc/ports/notes.osf1 + + Added notes file from DEC Alpha OSF/1 port. (6/21) + +sys/fio/fioclean.x +sys/fio/stropen.x + Two new internal routines str{set,get}mode were added to stropen.x. + These are used to set or query the file access mode as stored for + the string file, which represents these in a file-dependent way. + fio_cleanup was modified to force the access mode of a string file + to READ_ONLY before closing it during file cleanup, to prevent the + writing of the trailing EOS when closing a string file opened for + writing. The latter could cause a segmentation violation if the + string buffer was no longer in a mapped region of memory, as is + possible if the string file is still open (i.e. not closed normally) + following task termination when fio_cleanup is called. This problem + was found when testing the OSF/1 version of IRAF. (6/21, merged from + OSF1 revision of 6/06) + +dev/termcap + Added "lp" as an alias for "lpr". (6/26) + +dev/hosts + Added solstice to the downtown servers (tucana,ursa,gemini,orion,bigx) + at Ed Anderson's request (6/26 RLS) + +unix/hlib/mkpkg + Changed "mkshlib.csh" references to "./mkshlib.csh" to make the + script more robust in cases where the user has the path screwed + up. (7/03) + +dev/tapecap + Added support for device mtc|mtcc for BIGX, an HPDAT drive using the + ST driver. Also generic device st-hpdat, the HPDAT on ST. (7/18) + +dev/hosts + Added aten, volans, & musca to all servers, deleted vegemite (7/18 MJF) + +dev/hosts + Added soleil to all downtown server at Ed Anderson's request. (7/27 MJF) + +sys/fmtio/strdic.x + Was not ignoring leading whitespace on the string to be tested, when + computing the length "len" of the string. (7/31) + +pkg/proto/t_wcsreset.x + Added an error check to the mw_openim command so wcsreset can erase + the world coordinate systems of images with wcss that it cannot + read correctly. (1/8/95, Davis) + +pkg/xtools/inlfit/incopy.gx +pkg/xtools/inlfit/incopyr.x +pkg/xtools/inlfit/incopyd.x + Changed 4 MEMP (Memi) references to Mem$t references. (02/8/95, Davis) + +dev/tapecap + Modified gemini entry to change WangDat to an HP drive. (8/10) + +sys/fio/zzdebug.x + Replaced the t_ndopen debug task by a more recent version. (8/28) + +lib/gio.h +sys/gio/gplcache.x +sys/gio/gctran.x + The WCS transformation caching mechanism used in gctran was not + reliable and could fail in some cases where the WCS was changed more + frequently than gctran was called. To make caching of WCS related + information more robust a new field GP_WCSORD was added to the GIO + descriptor. This is set to a unique integer ordinal when a WCS is + fixed. If the ordinal changes any routines that cache WCS information + should invalidate their cache (unless they cache it on the basis of + WCSORD). WCSORD will differ for WCS stored in different graphics + descriptors, so testing WCSORD also does an implicit test that the + GP has changed. (8/28) + +sys/mwcs/iwewcs.x + Modified so that if an image contains a partial Lterm consisiting + of an LTV but no LTM, the missing LTM will default to the identity + matrix instead of the zero matrix (the latter causes a segvio if you + try to invert it). An image with a zero LTM is illegal but MWCS + should not die with a segvio in this case. (8/29) + +sys/imio/immaky.x +sys/imio/mkpkg + When copying an image section IMIO will call MWCS to update the Lterm + of the output image. This requires that it load any existing WCS + so that it can be modified and written out to the output image. IMIO + was modified to put the mw_open in an iferr block, printing a warning + message if the WCS cannot be loaded, rather than aborting the immap. + Aborting means that all IRAF imaging tasks fails to access the image + if it contains a WCS of a type not supported by IMIO. (8/29) + +sys/mwcs/iwgbfits.x + The code which reads in multiline FITS strings (WATi_j etc.) would + always read 68 characters per card. This was changed to read at + most 68 characters, terminating if newline, EOS, or a single closing + quote is seen in the input data. This allows the string on a line to + be less than 68 characters. It also avoids a bug seen with non-blocked + headers where the cards may contain less than 80 characters. (8/29) + +sys/mwcs/iwpstr.x + The final card of a multi-card string is no longer blank filled, i.e. + the closing quote will appear at the end of the string instead of in + column 80. (8/30) + +sys/mwcs/mwsaveim.x + The code which puts spaces between a sequence of attribute=value + keywords in a WCS attribute list was improved to avoid an unnecessary + space at the end of the list (spaces are now only used between the + members of the list). (8/30) + +sys/imio/db/impstr.x + When writing a string valued parameter the code checks for a trailing + quote and tries to add one if it is missing. The closing quote is + omitted if it would overwrite a data character - it isn't required + when reading cards unless the string ends before column 80. (8/30) + +sys/mwcs/mwsave.x + The DBUF offset in the save header was not being aligned to double. + (8/30) + +------------------------------------- +V2.10.4 patch 1 generated. (8/30) + +doc/rev2.hlp + Renamed this file to rev2.txt, it is not a help file. (9/03) + +unix/boot/bootlib/osfiletype.c + Added ".gz" to the list of "source" file types. Also added ".fit" + as an alias for ".fits". (9/03) + +mkpkg +noao/mkpkg + Added entries for linux and linuz architectures. (9/06) + +unix/hlib/strip.iraf +noao/lib/strip.noao + Replaced by updated versions, some files moved around and others + have been added. (9/06) + +local/.cshrc + Added "." and moved /usr/lang up in the hierarchy. (9/21) + +hlib/extern.pkg + Added the helpdb for the finder package on gemini and ursa. The + package is still loaded through the nlocal package. (10/12 RLS) + +sys/mwcs/imwcs.h + CROTA was being stored internally as an integer, causing small + truncation errors of non-integral rotational angles. (10/18) + +dev/graphcap +dev/imtoolrc + Added a new 8192x8192 frame buffer (imt7|imt8192). Redefined the + old imt7 (imt4x1) as imt19. (11/01) + +pkg/images/tv/imexamine/ierimexam.x +pkg/images/tv/imexamine/stfmeasure.x + +pkg/images/tv/imexamine/starfocus.h + +pkg/images/tv/imexamine/mkpkg +pkg/images/tv/doc/imexamine.hlp +lib/src/imexamine.key + New FWHM estimates based on the enclosed flux and a direct + measurement were added to the 'a' and 'r' keys. The weights for + the Gaussian fit were modified to reduce the influence of pixels + outside the half-maximum radius. The ? help and help page were + revised to described the new output and algorithms. (11/09) + +dev/hosts + Added 'inti' to all downtown servers. (11/20 MJF) + +pkg/images/median.par +pkg/images/rmedian.par +pkg/images/mode.par +pkg/images/rmode.par +pkg/images/fmedian.par +pkg/images/frmedian.par +pkg/images/fmode.par +pkg/images/frmode.par +pkg/images/doc/median.hlp +pkg/images/doc/rmedian.hlp +pkg/images/doc/mode.hlp +pkg/images/doc/rmode.hlp +pkg/images/doc/fmedian.hlp +pkg/images/doc/frmedian.hlp +pkg/images/doc/fmode.hlp +pkg/images/doc/frmode.hlp +pkg/images/filters/t_median.x +pkg/images/filters/t_rmedian.x +pkg/images/filters/t_mode.x +pkg/images/filters/t_rmode.x +pkg/images/filters/t_fmedian.x +pkg/images/filters/t_frmedian.x +pkg/images/filters/t_fmode.x +pkg/images/filters/t_frmode.x + Added a verbose parameter to the median, rmedian, mode, rmode, fmedian, + frmedian, fmode, and frmode tasks. (11/27/95, Davis) + +dev/hosts + Corrected path to irafks.e for cephus on all servers (11/30 MJF) + +unix/boot/spp/xpp/xppcode.c + Modified XPP to make keyword recognition case sensitive. Keywords + such as "int", "char", "procedure", etc. must be lower case to be + recognized. This permits macros to use the upper case versions of + these keywords. (12/05) + +pkg/cl/debug.c + Added INDXINCR and PUSHINDEX to the debug code. (12/14) + +pkg/cl/builtin.c +pkg/cl/compile.c +pkg/cl/debug.c +pkg/cl/exec.c +pkg/cl/grammar.y +pkg/cl/main.c +pkg/cl/opcodes.c +pkg/cl/opcodes.h +pkg/cl/prcache.c + 1. Fixed minor bugs in the CL array code which showed up on the 64bit + DEC Alpha. The array code had builtin assumptions about the size of + structures stored in CL memory, but on 64 bit systems the CL stack + and dictionary have a 64 bit memel size, rather than 32 bit. + + 2. Added a new builtin "d_trace" which permits instruction and + process tracing during execution. Typing d_trace without any + arguments toggles this feature. An optional argument 0 or 1 may be + used to disable or enable instruction tracing. A source line trace + feature might have been nicer, but instruction tracing should still + be of use for tracking down bugs in scripts, or otherwise revealing + what is going on when the CL executes a task. (12/16) + +sys/fmio/zzdebug.x + Added a parameter to the create datafile task to allow specification + of FM_MAXPTPAGES (max page table pages), for testing large datafiles. + (12/18) + +dev/hosts + Added new solaris machine oso to all servers. (1/29/96 MJF) + +pkg/images/imarith/imexpr.gx + Modified imexpr so that it will accept an image name that looks like + a number in the first few characters, but which is really an image + name. For example, "123.imh" or "../foo.imh". The previous version + of imexpr was treating any string which looked like a number in the + first few characters as a numeric constant. (2/8/96 LED 2/14 DCT). + +dev/hosts + Eliminated all references to /gemini and /ursa since all machines + have been updated such that /iraf is the correct path. Merged all + changes from other servers to tucana so all hosts files are now + identical, new machines added include ozzie, verdi, corondito and + pearl.kpno. Backups of previous files will be maintained. (2/14 MJF) + +pkg/images/geometry/t_geotran.x +pkg/images/geometry/geograph.x +pkg/images/doc/geomap.hlp + Corrected the definition of skew in the routines which, compute the + geometric interpretation of the 6-coefficient fit, compute the + coefficients from the geometric parameters, and in the relevant help + pages. (2/19/96, LED) + +sys/fio/zzdebug.x + Spiffed up the "daytime" debug/test task to permit entry of a host + name, so that one can use this to find out what time it is at some + site halfway around the world. (2/23) + +pkg/images/tv/imexamine/iejimexam.x +pkg/images/tv/jimexam.par +pkg/images/tv/doc/imexamine.hlp + There were several errors in this which only showed up when using a + world WCS. The parameter prompt and help now indicate the initial + sigma value is in pixels even when fitting in world coordinates. + (2/27/96, FV) + +pkg/images/tv/imexamine/iemw.x + The inverse WCS function was incorrect and is fixed. (2/27/96, FV) + +pkg/dataio/doc/rfits.hlp + Added a note about support for unsigned short integers to the + rfits help page. (2/27/96, LED) + +pkg/xtools/icfit/icvshow.gx +pkg/xtools/icfit/icshow.x +pkg/xtools/icfit/icerrors.gx + All output except the tabular part of :xyshow now begins with + the comment character. (2/29, Valdes) + +pkg/utilities/curfit.gx + Removed repeated output and added a comment character to the table + header line. (2/29, Valdes) + +dev/hosts + Changed GONG machines soi/mdi to use bin.ssun after solaris upgrades. + (3/8/96 MJF) + +sys/fmio/fmio.h +sys/fmio/fmlfopen.x +sys/fmio/fmlfbwr.x +sys/fmio/fmlfbrd.x +sys/fmio/fmioextnd.x +sys/fmio/fmclose.x + 1. Changed the lfile pagemap (LF_PAGEMAP) from type short to int. + This is entirely an internal array, created at lfile open time from + the global pagemap, and never written out, so there should be no + problem changing the datatype of the array. A type short lfile + pagemap limits the maximum datafile size by limiting the max file + offset to 32K datafile pages. This is not a problem for the global + page table as the global table stores the lfile number in each PTE, + with the offset of the PTE entry giving the associated file offset + (page number). + 2. Increased the default lfile pagemap size and increment on + overflow. (3/11) + +lib/qpset.h +sys/qpoe/qpoe.h +sys/qpoe/qpstati.x +sys/qpoe/qpseti.x +sys/qpoe/qpopen.x +sys/qpoe/qpmacro.x +sys/qpoe/qpbind.x + Added a new parameter "maxptpages" (QPOE_MAXPTPAGES) to QPOE. This + is a datafile control parameter similar to "maxlfiles" or "pagesize". + The pagesize and matptpages together determine the maximum datafile + size. In the past we have had to increase the pagesize to accomodate + very large datafiles, but beyond a certain point it is better to + increase the maximum page table size (maxptpages). Since QPOE files + can be very large it is necessary to allow control of this parameter + from within QPOE. (3/11) + +dev/hosts + Added Doug Geisler's machine kukita to all servers. (3/11/96 MJF) + +sys/fmtio/dtoc.x + Added some rounding to avoid printing numbers such as 12:29:60.0 + when formatting sexagesimal (HMS or MS) numbers. (3/12) + +sys/mwcs/iwewcs.x + Modified the code which computes the CD matrix from CDELT/CROTA. + The old code computed the diagonal (scale) terms correctly but the + rotation terms were evidently incorrect. The old code was based on + the 1988 Hanisch and Wells WCS paper and the new code is based on a + more recent paper by Mark Calabretta et. al. which supercedes the + 1988 representation. The affect of this change should be limited + as it only affects rotated images for which CDELT is given but no + CD matrix is defined. (3/13) + +pkg/images/tv/src/iecolon.x +pkg/images/tv/src/starfocus.h +pkg/images/tv/src/stfmeasure.x +pkg/images/tv/src/ierimexam.x +pkg/images/tv/rimexam.par +pkg/images/doc/imexamine.hlp +lib/scr/imexamine.key + The radial profile fitting and width measurements now have an option to + use a Gaussian or Moffat profile model. The model is selected by a + new "fittype" parameter. A new "beta" parameter may be specified as + INDEF to be determined from the fit or have a fixed value. The Moffat + profile model does better in producing consistent FWHM values so + this is the default. (3/16, Valdes) + +math/gsurfit/gsrestore.gx +math/gsurfit/gsrestorer.x +math/gsurfit/gsrestored.x + Changed the type declaration of the xmin, xmax, ymin, ymax variables + from real to PIXEL to avoid machine precision problems. (3/21 Davis) + +pkg/cl/builtin.c + Modified the clprintf code to support INDEF operands. (3/23) + +pkg/images/tv/imedit/epsearch.x +pkg/images/tv/imedit/epgcur.x + 1. The search algorithm produced incorrect results if part of the + aperture was off the edge (negative image coordinates). + 2. The rounding was incorrect when part of the aperture was off the + edge (negative image coordinates). + 3. A floating operand error occurs when a key is given without + coordinates. + (3/26, Valdes) + +pkg/plot/t_implot.x + When the vector being plotted was constant the 'l' and 'c' keys + selecting lines/columns from the right plot axis did not work. The + code was fixed for this case. (3/27, Valdes) + +pkg/images/geometry/xregister/rgxfit.x + Changed several Memr[] references to Memi[] in the rg_fit routine. + This type conversion bug was causing a floating point error + in the xregister task on the Dec Alpha machines if the coords file + was defined, and could potentially cause problems on other machines. + (Davis, April 3, 1996) + +unix/os/gmttolst.c +unix/boot/bootlib/ostime.c + Removed the type long variables gmtl, lstl and modified all calls to + localtime() so that the argument is of type time_t. This is standard + for all modern systems. Some older systems still require that the + argument be type long, but as this is nonstandard it should be + ifdef-ed in the source for these older systems. (4/04 1996) + +unix/hlib/libc/libc.h + The macros Memcptr and Memiptr included a "+ 1" which shouldn't have + been there. The one indexing correction was already being done in + the Memc/Memi macros and Memcptr/Memiptr take a zero indexed C pointer + as input. This was causing a bug in LIBC version of realloc, which + is not used anywhere in the IRAF system code. (4/05) + +pkg/images/tv/imexamine/ierimexam.x +pkg/images/tv/imexamine/stfmeasure.x + Fixed incorrect datatype declaration "real np" -> "int np" in various + related places. (4/9/96, Valdes) + +unix/os/zmain.c + Added a #ifdef SYSV conditional to change the calling sequence for + setpgrp() for SYSV and BSD systems. (4/24) + +sys/imio/iki/plf/plfopen.x + Fixed an imerr() call which had the wrong argument type. (5/06) + +sys/libc/realloc.c + Modified to work when called with a null pointer. (5/06) + +sys/gio/stdgraph/stgdrawch.x + The text drawing routines were not controlling the polyline width + when drawing characters in software mode using polylines. There is + no line width attribute for graphics text and we probably don't want + one, so the code was modified to force the line width to 1 when + drawing software characters. (5/10) + +unix/boot/bootlib/osgetenv.c + The envinit code calls _os_getenv to fetch the value of "pkglibs". + This code assumes that _os_getenv returns the string argument, but + nothing was being returned if the named environment variable was not + found. Changed it to return a NULL-terminated empty string in this + case. (5/10) + +sys/etc/mkpkg +sys/etc/onentry.x +sys/etc/main.x +unix/os/zmain.c + 1. The IRAF main (irafmn) was changed to an integer function and + modified to return an exit status. If a task aborts and the main + exits without running any more tasks (as when executing a task at + the host level where only a single task is run) then the error status + of the task is returned. In normal use as a connected process this + condition never occurs and the main always returns XOK as the status. + + 2. Several calls to sys_panic in various etc$ routines were modified + to ensure that a zero error code is not returned. sys_panic returns + the error code as the exit status of the process. + + 3. The process main (zmain.c) was modified to call IRAF_MAIN as an + integer function and to return its exit status. + 4. The call to exit() in zmain.c was changed to _exit(). (5/11) + +pkg/plot/t_graph.x +pkg/plot/graph.par +pkg/plot/doc/graph.hlp + Added parameters "ltypes" and "colors" to specify a list of line types + and colors when doing multiple data sets. (5/13, Valdes) + +---------------------------------------- +V2.10.4 patch 2 release. (5/22 1996) + +unix/boot/bootlib/envinit.c + Fixed a typo in some code that went "printf (stderr, ...)" (should be + fprintf), also changed following fflush to flush stderr. (5/27) + +unix/boot/bootlib/vfn2osfn.c + Deleted some unneeded semicolons from some stub routines, e.g. in + "KI_SEND(){};" the ; should not be there.

(5/28) + +unix/boot/rmfiles/mkpkg.sh + Added a (char *) declaration for vfn2osfn(). (5/28) + +pkg/cl/grammar.h +pkg/cl/globals.c + Added global definitions for parse_state, proc_script, and parse_pfile + to globals.c and modified grammar.h to define these as extern (found + with the IRIX 5.3 port). (6/03) + +pkg/obsolete/<imcombine> - + The old (V2.9) IMCOMBINE task was removed.

(6/14 FV) + +pkg/proto/generic/ + +pkg/proto/imfunc.x -> generic/ +pkg/proto/imrep.x -> generic/ + Added a generic directory for generic files.

Two new tasks were also added, TEXT2MASK and + MASK2TEXT, that convert from the old text file description to mask + images and back. The MASK2TEXT task is hidden to discourage + continued use of the text file description. (6/14 FV) + +unix/boot/spp/xc.c + Fixed a couple bugs in the PKGENV processing code. (7/05) + +doc/ports/notes.irix + + Installed the notes file from the IRIX 5.3 port. (7/07) + +unix/os/irafpath.c + Added entries for Solaris, Linux, FreeBSD. (7/17) + +unix/os/zfaloc.c +unix/os/zfiobf.c + Changed type of lseek() to off_f. (7/17) + +unix/boot/spp/xpp/xppcode.c + Changed warn() to a static function. (7/17) + +mkpkg +noao/mkpkg + Added an entry for the "freebsd" architecture.

This made it necessary to + change the disk image format, since the old format only allowed 80 + characters for the pixel file pathname. In the process reading and + writing the disk header was separated out from the in-memory + header. Support for two versions of the image and pixel file + headers were added. The "magic" string in the image or pixel file + header identifies the version. Old (version 1) image headers have + "imhdr" at the head of the file, with the string in SPP chars. The + new (version 2) headers have "imhv2" as the magic string. V2 headers + are byte packed and machine independent. The path limit is 255. + (3/31) + +sys/imio/immaky.x +sys/imio/imrdpx.x +sys/imio/imwrpx.x + 1. Support was added for byte swapping pixels. With the machine + independent V2 image header, this allows .imh images to be read on + any node (integer) or any IEEE-compatible node (floating). The + pixels are written in the native swap order of the creating host, + but the order is recorded in the IM_SWAPPED field of the image header, + and IMIO uses this to determine whether or not the pixels need to + be byte swapped during i/o. + 2. Minor changes to trim junk data after EOS delimited strings. + Since the V2 headers are byte packed the string data in these headers + can be viewed with Unix tools such as "less" and "strings". (3/31) + + Some pointers: "strings foo.imh" (or other tools like less) can be + used at the Unix level to look at V2 image headers. New images are + always written with host-native binary format pixels, so there is no + byte swapping involved for images read and written on the same + host. Images can any other (IEEE) host can be read or written but + there may be some slight overhead for byteswapping. If the image is + rewritten however using imcopy, the bytes will be swapped to the + native ordering of the new host. + +pkg/images/imutil/src/imheader.x + The only change so far was to eliminate some histogram dependence, + since this unused feature was removed from the standard IMIO in-memory + image header.

(4/01) + +sys/imio/immaky.x + When the header of an old image is copied during an open-new-copy, + IMIO now recomputes the length of the user area of the input header. + Formerly if the header had grown since the image was opened, the + added data could be lost in a subsquent new-copy operation.

"min_lenuserarea" is now supported as for IMIO (since IMFORT is + host level it must be defined in the host environment).

Combined + with the X segmentation of lines into blocks of at most 4095 pixels, + this should allow masks to be nearly any size despite the use of + short integers for the encoding. (4/05) + +sys/qpoe/qpiolwcs.x + Modified the LTV_2 term of the logical transformation to set the + fractional pixel zero point resulting from blocking the input data. + If for example 2 input pixels map to 1 on output, the range of the + output pixel (e.g. 0.5 to 1.5) maps to the range covered by the two + input pixels (e.g. 0.5 to 2.5), and the center of the output pixel + (e.g. x = 1.0) maps to the center of the range spanned by the input + pixels (e.g. 1.5). For 3 to 1, 1.0 maps back to 2.0 in the input, + for 4 to 1, 1.0 maps back to 2.5, and so on as (block+1)/2. (4/05) + +sys/ki/kfmkcp.x +sys/ki/kfrnam.x + These routines use a locally dimensioned buffer which was causing + filenames to be truncated at 128 characters. Increased the file + length limit to 256.

(4/06) + +unix/boot/spp/xc.c + The XC compiler was modified to improve support for multi-language + and host software development. These changes should be transparent + and should not affect conventional IRAF softwrae development. + + 1. Various buffer sizes were increased. + 2. The environment variables XC-CC, XC-F77, XC-LINKER can now be + specified to override the builtin default program name strings. + + 3. New command line flags: + -D<str> Pass -D<str> to the host compiler (does a #define). + -I<dir> Pass -I<dir> to the host compiler; for includes. + The directory name can be an IRAF VFN. + -Inolibc Disables -Ihlib$libc, which is the default. Use if + you want to use the host rather than LIBC <stdio.h>. + -L<dir> Can be used to specify a directory to be searched + for library files. + -H This is used like -h to link a host program, but + unlike -h it causes the main IRAF libraries to be + searched. + -V Print the XC version number. + + 4. XC now reads the "pkglibs" environment variable after processing + all package includes, and converts this into a list of -I<dir> flags + which are passed to the host compilers. This allows host include + files to be placed in package libraries. As noted above, hlib$libc + is automatically included unless the -Inolibc switch is specified. + + Note that -/foo can still be used to pass "-foo" to the host + compiler. (4/07) + +unix/boot/bootlib/envinit.c + "loadpkgenv" is called by HSI programs like XC and MKPKG when a + package environment is loaded (-p pkname). loadpkgenv was modified + to allow it to be called as loadpkgenv(NULL) or loadpkgenv("iraf"). + This mode causes the package environment for the core IRAF system to + be loaded. This was done formerly as well, but only if a -p switch + was given causing loadpkgenv to be called (in other words the core + IRAF package environment was not being fully loaded consistently). + (4/07) + +unix/hlib/zzsetenv.def + Added a line "set pkglibs = hlib$libc/" to zzsetenv.def.

Various + definitions were #ifdefed to be skipped if already defined, e.g. + stuff like min and max. A define for abs was added. + + 4. stdio.h will automatically load <libc.h> (if not imported etc.). + Since libc.h autoloads spp.h this means that C files which include + <stdio.h> from LIBC will automatically load spp.h and libc.h; these + contain the main LIBC definitions and often used IRAF defines such + as OK, ERR, INDEF, NEW_FILE, SZ_FNAME, etc. etc. A standard Unix + C source file which includes <stdio.h>, if compiled with XC or with + -I$hlib/libc will automatically be compiled using LIBC and will be + usable in an IRAF program. + + 5. varargs.h now includes /usr/include/varargs.h explicitly instead + of <varargs.h>, which causes an infinite preprocessor include loop. + On SunOS systems this causes a compiler warning message so the contents + of the SunOS varargs.h are included instead. For Solaris mkpkg.sf.SSUN + is used to employ a flag -erroff=XXX to disable the warning.

(6/19) + +sys/imio/iki/fxf/fxfopen.x + Fixed a bug that would affect opening of simple (not multi-extension) + FITS files without specifying an extension. (6/19) + +sys/imio/iki/oif/oifopen.x +sys/imio/iki/plf/plfopen.x +sys/imio/iki/qpf/qpfopen.x + These kernels were updated to check the image extension index and + abort if an illegal extension is referenced. For a simple file with + one image the only extension permitted is [1] (or -1 which is what + the kernel gets if no extension is specified). Trying to open [0] + or [2] or higher is an error. This is necessary to provide a kernel + independent behavior if other kernels may support multiple extensions. + + There are still two unresolved issues here. The first is that STF + was not also updated, so its behavior is inconsistent compared to + the other kernels ([0] or [1] or not given will all return the first + image). This could not be modified due to the risk to STSDAS and + the tight schedule we have for V2.11. The second problem is that + the FITS kernel used in the simplest manner will produce a + multi-extension file with [0] as the first image. In this mode the + FITS kernel has images starting at [0] whereas the first image is + [1] for the other kernels. This is less of a problem if the PHU of + a FITS MEF file is a dataless file header, in which case the first + image is [1], and [0] is the file header, not an image. But there + is an inconsistency. Perhaps the default behavior of the FITS + kernel should not so easily create a multi-extension file with a PDU + instead of a dataless PHU. We might want to change the default + behavior to add a file PHU when a multiextension FITS file is + created, or add a kernel switch to force creation of a PHU. Simple + FITS files would remain a simple PDU with no extensions.

(6/25) + +unix/hlib/zzsetenv.def + Added an "imextn" entry to the default IRAF environment so that the + user can do a "show imextn" to see the current mappings of image + extensions to image kernels. (6/25) + +--------------------------------- +V2.11 Beta-2 installed on NOAO servers. (6/25) + +unix/hlib/zzsetenv.def + 1. Added "imclobber = no". + 2.

(7/29) + +pkg/images/imutil/src/imhistogram.x +pkg/plot/phistogram.x + Fixed a bug in the imhistogram and phistogram tasks that could produce + invalid floating point operation errors if the image pixel values are + outside the legal integer range. (7/31 LED) + +sys/imio/iki/fxf/fxfksection.x + There was a typo on line 177, PHULINES should have been EHULINES. + (7/31) + +pkg/dataio/fits/fits_read.x + Fixed a bug in the new global header reading code that could + result in the global image header being left in the tmp$ directory. + (8/6 LED) + +dev/emacs.ed + Fixed an ambiguity affecting MOVE_LEFT and DEL_CHAR. Added ctrl/d + as a second eof char (along with ctrl/z) as for vi.ed. (8/07) + +sys/imio/iki/fxf/fxfrfits.x + Fixed a bug which would cause unwanted blank lines to be added to a + header generated with INHERIT=T when there are blank lines near the + top of the existing extension header. (8/08) + +sys/mtio/mtrewind.x + The sequence close(mtopen()) was being used to rewind a device. + The close could fail due to an invalid file descriptor if the mtopen + failed, as when opening a device and no tape was loaded. Modified + to do the close only if the open succeeds. An attempt to rewind a + device when no tape is loaded will still fail with a "cannot open + device" message. There is no way to tell that a tape is not loaded. + (8/08) + +pkg/cl/builtin.c + [This was the solution to the so-called "imdkern" bug]. Stty has + the unusual side affect of writing to environment variables (to set + the screen size etc.). Environment variables set in the CL are + automatically passed to all connected subprocesses. This can cause + corruption of the IPC prototcol when stty is called in response to a + pagefiles() call in a running task and a connected graphics kernel + is running at the time. The safest thing is to have stty shutdown + any connected graphics kernels before executing, so a call to gflush + was added to the stty code in the CL. (8/10) + +sys/qpoe/qpaddf.x + A symbol reference (dsym) was being made before a stenter, but the + latter could cause symbol pointers to change. The code was reorganized + slightly to do the stenter before taking any symbol references. (8/10) + +sys/imio/iki/oif/oif.h +sys/imio/iki/oif/oifopen.x + The OIF kernel now recognizes an environment variable "oifversion" + which, if defined, specifies the file version for a new OIF image + (for example set oifversion = 2 produces format version 2 images). + If the variable is not defined, which is the default, the builtin + OIF default will be in effect and new-format images will be + generated. This variable is provided only for backwards + compatibility, e.g. when using V2.11 IRAF with old software which + cannot easily be updated.

A bug was fixed that would leave open file descriptors behind + when trying to open extensions beyond the EOF, e.g. when searching + for the last extension in a file. + 2. An operation such as "imcopy foo.fits[3] new.fits" would fail + with imclobber=yes if "new.fits" already existed, due to a problem + with error recovery. + 3. A new fkinit parameter "padlines" was added. Along with the + existing "ehulines" this permits control of the number of blank + lines at the end of a header (used for expansion). Whereas ehulines + defines the minimum size of an extension header when a new extension + is added, padlines defines the number of lines of padding to be + added when a EHU overflows and has to be extended. + 4. The FK code supporting FILENAME was deleted. It is difficult + for the FK to maintain this reliably (e.g. if a temp image is created + and later renamed), and it is felt that it is better to let the + application which creates FITS files control this parameter. If the + FK insists on writing it this interferes with the use of FILENAME by + the application. (8/11) + +sys/imio/iki/fxf/fxfrfits.x + A buffer was improperly dimensioned affecting the OBJECT keyword. + This could cause long image title strings to be truncated. SZ_EXTTYPE + was changed to SZ_CARD on line 708. (8/12) + +lib/prstat.h +unix/hlib/libc/prstat.h + A new process status value P_BUSY was added. (8/13) + +sys/etc/prseti.x + + A prseti routine was added to the process control interface, which + already provided a prstati. (8/13) + +sys/etc/mkpkg +sys/etc/prupdate.x + The prupdate routine, used to broadcast messages/commands to all + subprocesses (e.g. for set environment or chdir requests), was + modified to check the process status and only broadcast to processes + for which the process status is P_RUNNING. The process status for + a running process can now be set to either P_BUSY or P_RUNNING. + P_RUNNING indicates that the process is running, but is idle and + read to accept commands. P_BUSY means that it busy executing in a + mode where it cannot accept standard IPC requests. (8/13) + +sys/etc/prclose.x + Prclose will now close any process for which the process status is + other than P_DONE or P_DEAD, that is, any running process. (formerly + it was checking for status=P_RUNNING but we now have to allow for + P_BUSY as well). (8/13) + +sys/gio/cursor/mkpkg +sys/gio/cursor/gtropenws.x + When a graphics subkernel is connected to the CL the process status + is now set to P_BUSY. Graphics subkernels execute in a loop reading + GKI instructions and cannot accept standard IPC requests, such as + environment change requests, without corrupting the IPC protocol. + (8/13) + +pkg/cl/config.h + Increased a couple of history buffer sizes. In particular SZ_CMDBLK + is supposed to be larger than a line buffer and it wasn't after the + recent increase in the line buffer size. SZ_CMDBLK was increased + from 512 to 2048, and the history buffer size was increased from 2048 + to 8192. (8/14) + +pkg/images/immatch/src/imcombine/t_imcombine.x + Fixed a segmentation violation caused by attempting to close the + mask data structures which are not defined if an error occurs opening + the input or output images. (8/14 FV) + +pkg/system/rename.x +pkg/system/rename.par +pkg/system/doc/rename.hlp + The rename task was rewritten to hopefully make the code clearer and + easier to follow. The task now checks for the $/ characters in + root or extn replacement strings and prints an error message if either + of these characters are found. For completeness the field-editing + feature now permits "ldir" to be modified as well as "root", "extn", + and "all" (modifying the ldir part of a filename is another way to + move the file to the named directory). (8/15) + +doc/notes.v210 + +local/notes.v210 - +local/notes.v211 + + Broke the old notes.v210 into a frozen v2.10 notes file and a new + notes.v211 file for IRAF V2.11 and revisions. (8/15) + +unix/hlib/motd +unix/hlib/zzsetenv.def + System version changed to V2.11EXPORT. (8/15) + +unix/hlib/mkiraf.csh + For the NOAO servers we use a version of mkiraf which permits imdir + to include hostnames, e.g. imdir=tucana!/d0/iraf (this is not + currently included in the export version of the system). It turns + out that while this mkiraf script was setting imdir correctly in the + login.cl, it was not actually creating the directory if it didn't + exist. The local version of mkiraf was modified to use the iraf + version of mkdir in x_system.e. This avoids the problem with host! + and the unix csh/mkdir, and also works when the directory is on a + different host than the one executing the script. (8/16) + +pkg/images/imcoords/src/sffind.x + Fixed a type mismatch in a call to atan2. (8/18 LED) + +sys/imio/iki/fxf/fxfrfits.x + In fxf_load_header, the calculation of "totpix" could overflow a 32 + bit integer for large (e.g. 8K by 8K) images. The calculation was + changed to avoid overflow. A bug was also fixed affecting the use + of PCOUNT in the expression. The value returned for "totpix" is not + actually the total pixels in the image as the name suggests, but the + size in 2880-byte FITS logical blocks of the data area of the image, + the data area being the pixel matrix plus PCOUNT data units. At the + moment we want to minimize changes, but later we should make more + general modifications to the code to change the name of this + variable to something more descriptive. (8/18) + +unix/boot/wtar/wtar.c + Added a call to memset to zero the file header structure before + setting the field values. Unix tar on at least one platform (Digital + Unix) was complaining about unused fields of the tar file headers. + (8/20) + +dev/hosts + Added the Jannuzi/Dey machine chomper to all servers (8/20 MJF) + +dev/hosts + Added beet (Sol2.4 machine), mosaic machines rush and driftwood + along with all their aliases (8/20 MJF) + +bin.ssun/S11_5.4.e + + Added a V2.11 shared image linked for Solaris 2.4. (8/20) + +pkg/images/tv/display/dspmmap.x + There was a bug in the code when using pixel masks which gives + "Warning: PLIO: reference out of bounds on mask".

(8/21 FV) + +sys/mwcs/iwewcs.x + In the case of an image with more than 2 axes where CDELT/CROTA is + used instead of a CD matrix, the CDELT value for axes other than + the RA/DEC projection axes (or axes 1-2 if no projection) was + being discarded and replaced with cdelt=1.0. (8/21) + +pkg/images/imutil/src/t_imtile.x + Fixed a bug in the range decoding code that could produce an integer + divide by 0 if the range syntax in xtools$ranges.x was extended to + include zero (8/22 LED). + +pkg/cl/config.h + Increased the size of the stack and dictionary. The V2.11 changes to + SZ_FNAME affect storage allocation in compiled scripts, hence under + V2.11 scripts will use more space than they used to. (8/27) + +sys/mwcs/mwcs.h + Increased LEN_FC (the size of the compiled function call portion of + a runtime CTRAN descriptor) from 48 to 64. This descriptor is + internal to MWCS and the change should have no effect outside the + interface. (8/28) + +dev/graphcap +dev/imtoolrc + Updated a few of the KPNO instrument frame buffer entries in graphcap + and imtoolrc. Affected were cn# 26,27, 35-40. No others were + affected, only these KPNO-specific entries. (8/28) + +sys/imio/iki/fxfopix.x + Fixed a typo: IM_LEN(im) -> IM_LEN(im,1). Evidently the Sun Fortran + compilers didn't complain about this (it was found on AIX). (8/29) + +pkg/images/tv/imexamine/iepos.x + Added missing argument in fprintf call.

(8/29) + +pkg/plot/impstatus.x + In sl_getstr, changed "Memc[sl]" to "int(Memc[sl])" to fix a mixed + type mod function problem. This routine is a bit on in that it stores + a variable nlines, the number of status line lines, in a char variable + in a char array (but it should work). (8/29) + + +--------------------------------- +V2.11 Public EXPORT release. (8/29) + +sys/imfort/imfort.h +sys/imfort/imcrex.x + Added support for the "oifversion" environment variable to IMFORT. + This is identical to what is in IMIO. The default is version 2 (new) + format images. (9/05) + +sys/imfort/imwrhdr.x + In the process of making the above fairly simple addition I found a + bug in writing V1 headers: IM_V1HDRLEN was not getting set correctly + as the pointer was "im" instead of "v1". This was preventing imfort + from writing valid V1 image headers (and it appears that IMIO may have + the same problem as well, seen as the user fields of the header not + being written, although other code may patch up the header field later + in the case of IMIO). We did not see this problem earlier in IMFORT + since it had no way to write V1 format images. (9/05) + +sys/imfort/db/imgnfn.x + In the process of making the above fairly simple addition I found + another header related bug, this one appears to have been there for + some time. The phead.f test IMFORT task was only printing the + standard fields of the header, not the user fields, although it was + supposed to print the full header. Updated the relevant section of + code in the IMFORT version of db/imgnfn.x with the code from the + IMIO version of the file, which does not have this problem.

This routine uses a temporary file in some cases when changing the + size of the header. "close(in_fd)" could be called in cases where + this temporary file was not used. + 3. Added one conditional to fxf_header_diff() to return zero on 'diff' + when the file does not exist and we want to have a dataless header. + This also works when the want to append only a header.

(11/18 LED) + +sys/imio/mkpkg +sys/imio/imseti.x +sys/imio/imsetr.x + IMIO has long had the odd structure for imset where imseti would + call imsetr to set integer valued parameters. This worked, but it + is always a bad idea to involve the floating point unit in integer + computations, and we encountered a portability problem on one + platform in code that set a pointer value (SPP pointers are integers + but the value can be large enough to exceed the 24 bit integer + precision of a single precision real). Imseti and imsetr were + therefore broken out as two independent routines with integer or + real parameters set directly by one or the other. For backwards + compatibility either can still be used however to set any IMIO + parameter, subject to the implied conversion. (11/18) + +sys/imio/imstatr.x + + IMIO had imstati and imstats (string) routines but no imstatr, even + though there there is a imsetr. Added an imstatr.

In fxfupk.x, fxf_altmd, which converts from int to double when + applying bscale/bzero, would fail for in-place operations (which + is how it is being called by the FK). + + Some other minor changes. We will modify this code further later + to eliminate the temp file used when accessing byte image or short + images with non-unitary bscale/bzero. There may be some other + interim restrictions on updating byte images and so on. (11/24) + +sys/libc/scanf.c + Increased SZ_NUMBUF from 25 to 256.

In caseset() the first argument is a pointer value but it was + declared as an int. Changed to memel. This was causing switch/case + to fail on 64 bit platforms like the Alpha. + 2. There was also an apparent bug in the case of a string case + which could prevent use of character constants as cases. (12/07) + +pkg/cl/mem.h +pkg/cl/stack.c + The stack utility functions push/pop/ppush are used to push and pop + operands from from the control stack, which is an array of memel + (generic integer type memory elements, used to store values of + various actual types). "push" is used in a generic way in the CL to + push both types of values, but this could cause portability problems + on machines where e.g. int and pointer are not the same size. + Rather than try to remember to always cast things properly when + calling push, the functions were changed to pushmem/ppushmem/popmem, + explicit type memel, and push/ppush/pop were changed to macros that + automatically coerce arguments of any type to memel. Hence common + usages such as "push(0)" and "push(stkop(v))" are still acceptable + and should now be portable. (12/07) + +pkg/cl/gram.c + Changed a sscanf call in the code which parses a sexagesimal number + to operate in double instead of float.

(12/13) + +unix/os/zzstrt.c + The shared library mapping code was changed to add a check for minor + release shared images when searching for the shared image by OS + release.

The FK was revised to handle the case of writing to an image + which is being accessed using on-the-fly pixel conversion, e.g., a + byte image or a short image with scaling to real. The current + version of the FK only supports reading such images, so an attempt + to write pixels if OTF scaling is in effect causes an i/o error. + Opening the image read-write is permitted however, so that the + header can be edited. + + 2. The zfio code was reworked to eliminate the high level calls + which have crept in recently (syserr etc.). A FIO driver can make + only low level calls, e.g. to pure code routines or the iraf + kernel. Because the file driver is called by FIO, calling anything + that might call FIO can result in recursion and various nasty + situations we would prefer to avoid. To aid in implementing this a + status variable FIT_IOSTAT (as well as some extra space) was added + to the main FK descriptor. A read or write call will initially + set this to OK, but set a nonzero value if an error occurs or the + i/o operation is completed. The ZAWAIT routine later returns the + status to the caller.

The actual maximum number + open files may be less if the host system imposes a lower limit. + For example, the default limit is 64 on SUNOS and Solaris systems. + On PC Unix systems it is much higher.

Removed the maximum buffer size limits for the PR and ND + devices. These were formerly set to 4096. 4K used to be the + system buffer size for devices like pipes, however that was a + long time ago and I don't know if it is still the case. Probably + not, and it doesn't matter anyway so long as a pipe doesn't + circle back on itself. This probably won't affect performance + much, but it could, especially for ND connections which can carry + a lot of traffic. + + The KS limit was already set to 0. Since the KI and binary device + limits are already 0, this means that large transfers can be used on + IRAF networking connections, e.g., for image access. Large transfers + (100K or larger) are needed to achieve the high bandwidth provided + by modern Fast Ethernet or Gigabit Ethernet network interfaces. + We should do some tests at some point to see if we can get high + performance for remote kernel server image access using fast + networking and the new version of IRAF. Potentially, accessing + images in this way could be as fast or faster than accessing them + on a local hard disk. (12/04) + +lib/imio.h +lib/imset.h +sys/imio/immapz.x +sys/imio/imsetbuf.x +sys/imio/imseti.x +sys/imio/imstati.x + The following changes were made to enable IMIO to use larger + buffer sizes to optimize i/o for large images. + + The default file buffer size set by IMIO is unchanged: it is still + about 512 MB, the value set for V2.11.2. However, a new parameter + IM_BUFFRAC was added. Both IM_BUFSIZE and IM_BUFFRAC are used to + help determine the FIO buffer size set when an image is opened. + The logic for this is implemented in imsetbuf.x. + + Backwards compatibility. If you do nothing about IMIO/FIO buffers + in your program, the system may transparently use a larger buffer + for larger images. If you set BUFSIZE in your program, the system + will by default use the value you give, or possibly a larger value, + if the image you are accessing is very large. If you set BUFSIZE + and you want to guarantee that the value you set is used (even + for very large images) then you should also set BUFFRAC=0 to ensure + that only BUFSIZE is used. + + How it works. BUFFRAC specifies the default FIO buffer size used to + access an image, expressed as a percentage of the size of the + image. For example, the builtin default value of BUFFRAC=10 will + try to make a FIO buffer 10% of the size of the image. The actual + value used will be given by BUFFRAC, but will be at least BUFSIZE, + and no more than a builtin default maximum value, currently 32 MB. + Given the builtin defaults, the buffer size will range from 0.5 to + 32 MB depending upon the size of the image being accessed. As noted + above, BUFSIZE and BUFFRAC can be set to force the buffer size to a + specific value if desired. + + Environment variables for both parameters are provided. The names + are "IMIO_BUFSIZE" and "IMIO_BUFFRAC". If specified, these override + (at image open time) the builtin default values for both + parameters. An IMSET call by the application will override all such + defaults. + + The FIO buffer allocated will not be larger than the size of the + image. The FIO buffer will also not exceed the maximum size set by + the file driver being accessed. For example, for PLIO images the + file buffer will not exceed about 2KB, even for a very large mask. + This is because the "pixel file" for a PLIO image is dev$null, the + driver for which specifies a maximum i/o buffer size of 2K (the real + file to load or save the mask will use a different descriptor). + + The intent here is to provide an adaptive mechanism for setting the + FIO buffer size used to access an image, which automatically adapts + to the size of the image being accessed. If you access a lot of + small images you will get smaller buffers - everything will be as + before. If you access very large images, you may get large buffers + up to the builtin maximum value of (currently) 32 MB. + + Using large buffers could cause a machine to run out of memory. + However, it is likely that if someone is working on 300 MB images + that they are using a machine which has a memory at least that + large - probably larger.

Using buffers + larger than a certain amount (32 MB is generous) is probably + counterproductive. If the i/o system provides 20 MB/sec i/o + transfers, 32 MB will take 1.6 seconds.

Note this second ndopen + _will_ block if a client connection is not pending; usually some + external means will be used to avoid opening the client connection + until a client has made a connection attempt.

(01/01/2002) + +unix/os/zfiobf.c +unix/os/zfiobf.c [pcix] +unix/hlib/libc/kernel.h +unix/hlib/libc/kernel.h [pcix] + The binary file driver was modified to add VMcache client support. + This adds two new capabilities to the driver: 1) built-in support + for direct i/o (on systems that support it), and 2) a client + interface to the VMcache daemon to permit the daemon to optimally + manage binary file i/o if a VMcache daemon is present. + + Direct i/o is file i/o which transfers data directly between the + disk and process memory, bypassing system virtual memory. For small + files or usage patterns which do not involve heavy i/o, direct i/o + will usually provide lower performance than allowing the system to + buffer data in virtual memory. For large files or usage pattern + which involve very heavy i/o, however, use of direct i/o can prevent + paging and will avoid cluttering up system virtual memory with data + that will be only accessed once. A limitation of direct i/o is + it is only possible when i/o transfers are block aligned and are + an integral number of device blocks in size - this means that + direct i/o cannot be used with the current version of the FITS + kernel, which currently uses a host device block size of 2880. + Direct i/o is currently only available on Solaris systems (versions + 2.6/5.6 or greater - 5.5.1 is not supported). + + Use of the VMcache daemon allows the daemon to control how file data + is cached in virtual memory. This makes it possible to optimize + file access to avoid excessive paging (by freeing space used by low + priority files when new VM cache space is needed), and makes it + possible to cache images in memory for very fast access even by + separate processes (even including non-IRAF programs in many + cases). The VMcache daemon can manage direct i/o on the behalf of + clients, telling the client whether to use normal (VM buffered) i/o + or direct i/o. VMcache can also pre-fetch files so that they are + memory resident by the time the application references them. + + The VMcache daemon is a separate system-level program outside of + IRAF. This is necessary to provide a central system-wide cache + controller. It also provides flexibility, allowing multiple + versions of the daemon to exist, e.g., to allow experimentation with + different types of caching algorithms. It also allows easy + customization of the daemon independently of the IRAF applications + using the VMcache client interface. + + The VMcache client interface was added to the BF driver (rather + than SF) because VMcache is a general low-level file i/o facility, + useful for all file i/o. FMIO files for example (used for QPOE + images) are large binary files but FMIO uses BF and not SF. + + For the moment the VMcache client interface has been added to + zfiobf.c since this is the only system component which uses it. + We may move it out to a separate file later. Two environment + variables have been provided for customizing the behavior of the + client interface: + + VMPORT The tcp/ip socket to be used. The built-in default + is 8677. Both IRAF and vmcached will respond to + this environment variable if defined. + + VMCLIENT Initialization of the VMCLIENT interface. The + string value should be a comma-delimited list of + keywords or keyword=value terms. For example, + VMCLIENT="disable" or VMCLIENT="debug,threshold=8m". + + The keywords currently recognized by VMCLIENT are the following: + + enable Enable use of the VMcache daemon, if any. Used + without the "=value". + + disable Disable use of the VMcache daemon. Used without + the "=value". + + debug Set the debug level. Can be used as either "debug" + or "debug=value". Higher values generate more + detailed debugging messages. + + threshold The file size threshold for use of the VMcache + daemon. Even if use of VMcache is enabled, the + daemon will be used only if the size of the file + being accessed equals or exceed the specified file + size threshold. Smaller files are handled using + normal i/o and do not result in any communication + with the daemon. Values may be specified in bytes + or in kilobytes (k or K suffix) or megabytes (m or M + suffix). + + directio Use of this keyword enables directio and disables + VMcache. The value specifies the file size + threshold for use of direct i/o to access a file. + Files smaller than this value use normal (VM + buffered) i/o. If directio is specified for a + client then use of VMcache is disabled, and no + communication with the daemon will occur. Values + may be specified in bytes or in kilobytes (k or K + suffix) or megabytes (m or M suffix). + + The builtin defaults are VMCLIENT="enable,threshold=8m". + + Normally there will be no VMcache daemon running on a system. If + the VMcache client is enabled a connection attempt will be made each + time a file larger than the threshold is accessed. This is harmless + if no daemon is present, and does not measurably affect execution + time. If a daemon is started after a process is already running, + the process will detect the daemon automatically in the next + connection attempt. If a process is connected to a daemon and the + daemon dies or is killed, the process will silently detect this and + close the connection to the server. If the daemon is subsequently + restarted the client will reconnect.

There + are no build files as this version is still under development. + The code is complete but only enough debug/test was done to support + development of the VMcache client interface for IRAF (the vmcached + code is debugged but the new version of the vmcache library code has + not been tested). Since the daemon can be worked with outside + the normal IRAF release we do not have to fully develop it for the + release. + + It should be stressed that VMcache is only useful or warranted for + systems that are very data intensive. The standard host operating + system file access heuristics are best for "normal" processing where + either the system is not really busy, or the datafiles are not + excessively large. On systems with very large physical memories + where massive amounts of data are being processed, VMcache can make + a significant difference in overall system performance. + + VMcache is too complex to document here. Without going into the + details, its function is to manage a cache of files in system + virtual memory. Files can be explicitly cached or uncached, or they + can be "accessed", and VMcache will decide whether or not to cache + the file in virtual memory. This is what the VMcache client + interface does: every time it accesses (opens or extends) a file + larger then the VM threshold it sends an "access" directive to the + VMcache daemon. The daemon sends back a response of 0 (file not + cached; use direct i/o to access the file), or 1 (file cached in VM; + use normal VM-buffered i/o to access the file). Even if a file is + not cached the daemon keeps track of all accesses. Files which are + frequently accessed will have a higher prority and are more likely + to be cached in memory. + + IRAF uses only the access directive to interact with VMcache since + a general IRAF task cannot know how it is being used. Higher level + clients may more explicitly control the cache: for example, the + Mosaic DHS will explicitly cache new images as they are read out, + and will cause other file accesses to be given a lower priority. + Any client code can connect to the VMcache daemon. For example we + could add a unix-level task to be called from scripts for explicit + cache control, or a GUI to dynamically display the operation of + the cache and the utilization of system memory. + + The builtin-default cache algorithm implemented in the new version + of VMcache uses the following heuristics to determine whether a file + is cached: + + Factors determining if a file is cached: + + user-assigned priority (0=nocache; 1-N=cache priority) + number of references + time since last access (degrades nref) + amount of available memory (cutoff point) + + Cache priority + + priority = userpri * max(0, + (nref-refbase - ((time - last_access) / tock)) ) + + Tunable parameters + + userpri User defined file priority. Files with a higher + priority stay in the cache longer. A zero + priority prevents a file from being cached. + + refbase The number of file references has to exceed + refbase before the file will be cached. For + example, if refbase=0 the file will be cacheable + on the first reference. If refbase=1 a file + will only become cacheable if accessed two or + more times. Refbase can be used to exclude + files from the cache that are only referenced + once and hence are not worth caching. + + tock While the number of accesses increases the cache + priority of a file, the time interval since the + last access likewise decreases the cache + priority of the file. A time interval of "tock" + seconds will cancel out one file reference. In + effect, tock=N means that a file reference + increases the cache priority of a file for N + seconds. A frequently referenced file will be + relatively unaffected by tock, but tock will + cause infrequently referenced files to age out + of the cache within a few tocks. + + For example, the cache could be configured to not cache a file the + first time it is accessed, causing direct i/o to be used for a file + which is only accessed once. The second time a file is accessed + it would be cached in memory.

This is usually + a device sector (512 bytes), the physical storage unit of the + low level storage device. Formerly the FK was setting a pseudo + block size of 2880 bytes, however blocking and deblocking should + be done at the FIO level; if we try to do this in an IRAF file + driver then the host system is required to do blocking/deblocking. + Using transfers which are physically aligned at the hardware level + makes certain optimizations possible, such as direct i/o. + + 2. The imsetbuf routine in IMIO was modified to be a little smarter + in aligning the first file buffer for a pixel file. Formerly it + would only set the offset of the first file buffer if image lines + were aligned to device blocks. This is overly restrictive, and + doesn't work for FITS files. The code was changed to always set the + first file buffer offset for a pixel file, setting it to the offset + of the device block _containing_ the first image line. If the first + image line is not block aligned the FIO buf size is made larger by + the amount of the intra-block offset to ensure that it is big enough + to contain the computed number of image lines for which the buffer + was sized.

(3/10) + +unix/os/zgtime.c [pcix] + Added an include for <time.h> to pick up the CLK_TCK definition + to get things to build correctly on some PC-IRAF platforms.

(3/11) + +---------------------------------------- +Updated V2.12 BETA release; second public BETA release. (3/12/2002) + + +dev/imtoolrc +dev/graphcap + Added new stdimage devices imt45-imt49 submitted by Gemini for + GMOS CCD displays at various sizes. (3/14/2002, MJF) + +sys/imio/iki/fxf/fxfupdhdr.x + When copying an extension or subsection of an extension to a new + file some of the header keywords could be duplicated at the end + of the header. (3/15) + +sys/imio/iki/plf/plfupdhdr.x + If an error occurred while writing the header to a pixel mask + image the error handler in this routine would mask the error and + no error was being reported to the caller. (3/15) + +doc/newsfile +doc/v212revs.hlp + + Installed the V2.12 Revisions Summary and updated the 'news' command + files. (3/15/02, MJF) + +dev/hosts + Aliased 'ndws' to 'archive' (3/18/02, MJF) + +dev/hosts + Added new NDWFS RedHat machine 'dropbear' (3/19/02, MJF) + +pkg/images/tv/display/t_display.x + If an image section of a higher dimensional image is displayed the + image section is included in the image name sent to the display + server. Previously the section was stripped and so it was not + possible to know the 2D section displayed. For now we keep backwards + compatibility by stripping any section from 2D parent images. + (3/20/02, Valdes) + +pkg/images/tv/imexamine/iegimage.x + Image sections in the image name retrieved from the display server + are now handled more intelligently. In particular, 2D sections of + higher dimensional images will now examine the correct 2D section + rather than just the lowest 2D plane. (3/20/02, Valdes) + +pkg/dataio/export/export.h + Changed the zscale sampling parameters to use more points spread out + over more of the image. The old values would sometimes find an + innappropriate z1/z2 range causing problems when doing many images in + batch mode. (3/20/02, MJF) + +unix/hlib/install +unix/hlib/install [pcix] + A previous change that added a check for write permission on the iraf + tree (to edit paths) proved to be too restrictive when installing on + an NFS client node. The check was modified to allow the install to + continue without editing files if the user wanted, this would create + the local command links and device files but not edit the paths in + the iraf files. A '-noedit' option to force this behavior was also + added. (3/20/02, MJF) + +sys/imio/iki/fxf/fxfrfits.x + The limtime value calculated was off by a day after Feb 2002 and as + a result DATAMIN and DATAMAX were not being updated in headers. + Replaced the code which calculates limtime by a more robust calculation + based on the Julian day taken from asttools. (3/21) + +sys/imio/iki/fxf/fxfupdhdr.x + The update header code was modified to delete BSCALE and BZERO for + floating point images, just in case they are added to the header + by the application after the image has already been opened. + We may as well do this since the FK does not support use of scaling + when reading floating point images, and the presence of these + keywords in the header could cause an i/o error when the image is + later opened for reading (as seen in ST HSTIO code during testing + of V2.12). (3/21 NZ+DT) + +pkg/images/tv/tvmark/mkoutname.x +pkg/images/tv/tvmark/mktools.x + Fixed a bug in the default output image name code that would result + in hidden images with names like .snap.1, .snap.2, etc being written + if the display image name included a kernel or pixel section. + (3/21 LED) + +dev/hosts + Added redhat machines cholla and pym, removed pyxis (3/24/02, MJF) + +dev/hosts + Added the MacOS X host cetus.

(3/25/02, MJF) + +unix/hlib/install +unix/hlib/install [pcix] + Small change to allow a "no-edit" install to skip the configuration + stage (all of which require edit permissions). (3/25, MJF) + +noao/mkpkg + Added an entry for MACOSX. (4/02) + +pkg/images/imcoords/src/t_wcsctran.x + Added an error check for INDEF valued input coordinates. (4/04, LED) + +pkg/images/immatch/src/imcombine/src/icmask.x + There was a bug in the recent change to open and close masks as needed + where a possibly null filename pointer was being checked for being + a null string. (4/8/02, Valdes) + +pkg/lists/doc/Lintran.hlp +pkg/images/tv/iis/doc/Cv.hlp + The above files were rename to Lintran.spc.hlp and Cv.spc.hlp + respectively in order to work around upper / lower case file name + ambiguities in MACOSX. (4/11, LED) + +pkg/images/imcoords/src/t_ccget.x + Ccget was not transforming the units and applying the user supplied + formatting parameters if the input or output coordinate system, e.g. + ICRS, was the same as the catalog coordinate system. This bug does + not affect released code. (04/16/02, Davis) + +unix/hlib/install +unix/hlib/sysinfo +unix/hlib/install [pcix] +unix/hlib/sysinfo [pcix] + Mods and bug fixes needed for OS X (04/16/02, MJF) + +pkg/images/immatch/src/imcombine/src/icsetout.x + When computing offsets the registration point was the reference pixel + returned by mw_gwterm for the first image. The code then went on to + assume this was a logical pixel when comparing with the other images, + which is not true when there is a physical coordinate system. The + algorithm was fixed by converting the reference point to logical + coordinates. (4/18/02, Valdes) + +pkg/cl/main.c + The routines startup() and shutdown() in the CL main conflicted + with host library routines of the same name on MacOSX. Changed + these two routines plus login() and logout() to static functions. + Added a new external function cl_shutdown to allow the error + recovery code to get at the now static shutdown(). (4/21) + +pkg/cl/errs.c +pkg/cl/errs.h +pkg/cl/binop.c + Modified the interpreter binary divide operator to check for a + zero divisor and call cl_error if a divide by zero is attempted. + Added two new error actions for integer and floating divide by + zero. (4/21) + +unix/hlib/config.h [pcix] +unix/hlib/libc/spp.h [pcix] + Increased LEN_JUMPBUF to 1024 for this platform to allow for the + worst case jmpbuf for MacOSX (not sure why this can be so big but + it may be the altivec vector registers). (4/21) + +unix/boot/bootlib/rindex.c [pcix] +unix/boot/bootlib/index.c [pcix] + These functions conflicted with the host system versions due to + the dynamic libraries used on MacOSX. Redefined the names for + this platform to avoid the conflict (this is new since the initial + 10.0 port). (4/21) + +unix/os/zzstrt.c [pcix] + Minor modifications for MacOSX. Normally process startup exception + handling initialization is done in this file. For MacOSX nothing + is done at the moment (since the exception handling is mostly + done in software) but the LinuxPPC code had to be reworked somewhat + for MacOSX to build on both platforms. (4/21) + +unix/bin.macosx/mach.h [pcix] + + Installed a byteswap=NO version of <mach.h> in HBIN for MacOSX. + This allows the same PC-IRAF HSI to be used for both Intel and + PowerPC, which are byte swapped with respect to each other. The + default <mach.h> in HLIB is for Intel. Note that any versions + of the global system includes in the HBIN for a platform will + override the global HLIB versions. (4/21) + +unix/os/zzepro.c [pcix] + +unix/hlib/libc/knames.h [pcix] +unix/os/mkpkg [pcix] + Added a new routine ZZEPRO (ZZ End PROcedure) to the PC-IRAF OS. + This is present on all PC-IRAF platforms, but is a no-op (for now) + except on MacOSX. On MacOSX it calls an assembler routine to + read the PowerPC floating point status and control register (FPSCR) + to check if any floating point "exceptions" have occurred. + Currently the floating point exceptions are not enabled for MacOSX, + but the hardware will nonetheless set a bit in the FPSCR if one + of the IEEE-defined exception conditions occur. The ZZEPRO code + will check for a divide by zero, overflow, or invalid operand + exception condition, and if any of these have occurred, execute + a "software exception" by calling the exception handler in ZXWHEN. + The result is exactly the same as a real hardware exception, with + all the same semantics and error actions, except that the + exception condition is not detected until some time after the + instruction which caused it is executed. (4/21) + +unix/boot/spp/rpp/rpprat/endcod.r [pcix] +unix/boot/spp/rpp/rppfor/endcod.f [pcix] + Modified the SPP compiler to insert a call to ZZEPRO (see above) + to every SPP function or procedure. The call is made just before + the function exits. Note that since the check is only made at + the exit from a function, the exception condition often will be + detected in a routine called by the routine in which the + exception condition occurred. For example, if A does a 5.0/0, + then calls B, then B exits, the exception conditition will be + detected by the ZZEPRO call at the end of B. In all cases however, + it won't be very long before the exception condition is detected. + If external C or Fortran code is called an exception will not be + detected until execution resumes in an SPP function. (4/21) + +unix/os/zxwhen.c [pcix] + Added exception handling support for MacOSX. Also, ex_handler + (the exception handler) was changed from static to public so that + it could be called from ZZEPRO. (4/21) + +unix/as.macosx/zsvjmp.s [pcix] + 1. New version of ZSVJMP for MacOSX. This was very tricky to + implement for this platform but it appears to be working now. + ZSVJMP was difficult as it needs to call the host "setjmp" to + do the real work, but MacOSX has only dynamic libraries, so + the routine has to invoke setjmp from the system shared library + from the assembler code! (I think we need to do away with the + assembler version of ZSVJMP - might be possible by adding some + C code generation to e.g. F2C, so that the PC-IRAF implementations + at least could avoid assembler). + 2. New routines GFPSCR and SFPSCR added to get and set the FPSCR + register on MacOSX. (4/21) + +unix/as.macosx/ieee.gx [pcix] + Modified the invalid exception masking support for MacOSX. + Normally floating invalid exceptions are enabled, meaning that if + a NaN or Inf is encountered the invalid operand exception is + invoked. The invalid exception has to be masked in the IEEE + handling code, to allow IEEE NaN/Inf to be detected and replaced + when reading in floating data.

(4/22/02, Valdes) + +unix/hlib/install +unix/hlib/install [pcix] + Fixed a typo ('MAG' -> 'MSG' on line 1023). (4/22/02, MJF) + +unix/hlib/install +unix/hlib/install [pcix] + Modified to skip the /dev fifo and iraf user login checks which + aren't appropriate for OS X. (4/23/02, MJF) + +unix/boot/spp/xc.c + We had reports of XC not working properly with long filenames. + Changed a 256 char buffer in sys() to SZ_PATHNAME, and also + found a call to symlink() that was dimensioned 128 on the output + buffer even though the actual buffer was SZ_PATHNAME. (4/23) + +images$imutil/src/imadiv.gx +images$imutil/src/generic/imadiv.x + Fixed an error in the imarith code which evaluates an expression of the + form "inimage / 0". This was causing a bus error on the OSX but + apparently not on any other platform. (4/24/02, LED) + +local/.login [pcix] +local/.cshrc [pcix] + Modified to set proper environment for OS X (4/24/02, MJF) + +pkg/images/immatch/src/imcombine/src/icmask.x + The fix of 4/8/02 had been inadvertently undone. (4/25/02, Valdes) + +sys/imio/impmhdr.x + The im_pmldhdr code could go into an infinite loop when reading + a malformed PL imio save header. (4/25) + +sys/imio/iki/fxf/zfiofxf.x + The fxfzop routine had some invalid code at the end of the routine + which was incorrectly trying to set FPKOSFN in what it thought was + the parent file descriptor. (4/25) + +unix/hlib/install +unix/hlib/install [pcix] + 1) Not all failed tests were properly incrementing the error + counter leading to a confusing "successful" install. 2) Added a + new procedure to install symlinks to the .login/.cshrc files for + OS X installs where it's not easy to change the iraf user login + directory. Once the iraf path is edited into the files symlinks + are made in the account directory, which is normally /Users/iraf, + so the iraf user still have the proper environment. (4/26/02, MJF) + +unix/hlib/install +unix/hlib/install [pcix] + 1) The OS X csh didn't like if-stmts without a then/endif when the + test failed, changed all such occurrances. 2) Fixed small problem + with SunOS constructing the recommended hosts file entry. 3) Changed + the file ownership check from a fatal error to a warning. (4/30, MJF) + +pkg/images/imtuil/src/t_imstat.x +pkg/proto/masks/t_mimstat.x +pkg/proto/masks/rsstats.x + If nclip > 0 and the initial mean and standard deviation are INDEF + (a very unlikely occurence unless there is an input mask) the ksigma + limit computation in the imstatistics, mimstatistics, and rskysub + tasks could overflow.
