28. History

28.1 mgv 3.1.5: September 1998

• Fixed the mark even and mark odd toolbar buttons.

28.2 mgv 3.1.4: September 1998

• Fixed an auto sizing bug. Telling mgv to automatically resize both the width and height of the main window could cause X protocol errors and/or bizarre window sizes (okay, I admit it, I'm just trying to get a version number closer to pi: I have TeX-envy).

28.3 mgv 3.1.3: September 1998

• Added a simple work-around for a LessTif accelerator problem. Menu accelerators were going away as soon as you brought up a dialog box. This little work-around isn't needed unless you're using LessTif.

28.4 mgv 3.1.2: September 1998

• Netscape HTML help got broken in 3.1.0, I converted some fixed sized buffers to dynamically sized buffers and neglected to remove some memset calls.

28.5 mgv 3.1.1: September 1998

• Fixed a memory corruption bug, thanks to Stephen R. Veit for reporting the bug and a fix for it.
• Fixed up the XPM include logic.

28.6 mgv 3.1.0: September 1998

• Finally added a tool bar, you can change the images used but there is currently no way to change the entries without hacking the source.
• Switched to autoconf for configuration and compiling and there was much rejoicing. The autoconf/automake files for DDD and LessTif were invaluable. This change means that library files (help files, icons, splash screens, etc...) will usually end up in /usr/local/share because autoconf likes it that way; the new library directory will contain a subdirectory for each mgv version installed.
• Removed the LessTif Problems section of the manual, I don't know of any problems anymore.
• Added some simple hooks for malloc debugging via dmalloc (ftp://ftp.letters.com/src/dmalloc/dmalloc.tar.gz). If for some reason you want to enable dmalloc, make sure you configure dmalloc to allow freeing NULL pointers: ANSI guarantees that free(0) will work and I assume ANSI all over the place.
• Removed all instance of popen(3) from the source, this function has a history of compile problems so it went away.

28.7 mgv 3.0.2: August 1998

• Fixed an install problem in the lib directory, the makefile had an incorrect source path. Seems that my QA is lacking in some areas.

28.8 mgv 3.0.1: August 1998

• Added the version number to the library directory. Thanks to Marty Leisner for the suggestion.
• Fixed up a couple of compiler warnings.

28.9 mgv 3.0.0: August 1998

• Added panning as yet another scrolling option in the main viewing window. This lets you drag the viewing window around with mouse button two.
• Disabled editres support on everything but Linux and FreeBSD. Editres and the Xmu library were just causing build problems so they went away; I know it works on Linux and FreeBSD (as far as I know, XFree86 always comes with a fully functional Xmu) so I've left it enabled there.
• Fixed a window sizing bug with EPS and non-DSC files; automatic window sizing didn't do anything in these cases but now it works as expected. Thanks to Erik Luijten for pointing out the problem.
• Renamed the Window menu to View and moved it over the the third entry from the left in the menu bar.
• Removed the (deprecated in version 2.1) printer resource, the printer name is now officially part of the printCommand resource.
• Updated my sgml-tools to 1.0.6, some minor document hackery was needed for this.
• Fixed a Lesstif/Motif incompatibility with the file selection widget. I was setting the dirMask resource on file selection widgets to get a specific file name filter but Lesstif wants me to use pattern instead. Another reading of the Motif documentation has convinced me that pattern is the right one anyway.
• Dropped support for the (ancient) Mosaic/CCI help support. If anyone actually uses this I'll consider putting it back but I don't think it is worth the compile trouble.
• Removed a LessTif ifdef in wlib/create.c, gadgets seem to be working fine now.
• Changed the Center entry in the Page menu to a toggle button; page centering now stays around when you change pages. The -center and -nocenter switches and the center resource were also added.
• Fixed a bad memory free when reporting unknown switches. I was freeing an incremented pointer, how embarrassing. Thanks to Guenter Steinbach for reporting this problem.
• Added -? and -H as aliases for -help.
• Added some notes about binary distributions.

28.10 mgv 2.4.3: May 1998

• Added make, bindir, and libdir to the version information which appears in the Build Options dialog and the -version output.
• Fixed an ambiguous if statement in dsc.c. Thanks to Marty Leisner for the fix.
• Moved the INSTALL file to the top directory where it should be. Thanks to Marty Leisner for telling me about this brain damage.
• Two radio buttons in the Magstep menu could be turned on if you specified a non-default initial magstep. This problem was just cosmetic but a bug is a bug. Thanks to Erik Luijten for pointing out this problem.

28.11 mgv 2.4.2: April 1998

• Removed the SGI, CDE, and Xnt stubs in the help system. I never had a chance to implement any of these and I no longer have access to an SGI or CDE system so I've removed the stubs.
• Removed all traces of Xmu from the Ghostview widget. Many people seem to have old versions of libXmu or they don't have Xmu at all so Xmu had to go.
• Turned off editres support on AIX by default.

28.12 mgv 2.4.1: April 1998

• The wlib/resource.c file wasn't supposed to exist in 2.4 but I neglected to delete a CVS tag so it was there. This caused some build problems because wlib/wlib/wlib.h didn't have the necessary prototypes for wlib/resource.c. I have now properly killed wlib/resource.c.
• Added some missing null checks to some of the resource handling. The problem (a segfault) would only show up if mgv couldn't find one of the standard print commands in your PATH environment variable.
• Andrew 0. Smith informed me that Solaris's cc prefers -xO2 instead of the usual -O2 to get level two optimizations so I fixed the "make/sys.solaris-cc.mk" makefile.

28.13 mgv 2.4: March 1998

• Added the wlInstallIcon resource to control whether or not mgv installs its own icon when it runs. If you want to use a different icon, then you can just set this resource to false and tell your window manager to use your icon. Thanks to Hans Vahlenkamp for this suggestion. SGI users can use one of the mgv.icon* files as their icon if they wish (the images are pretty cheesy, if anyone wants to donate a better one, please do).
• Made editres support configurable at run-time (via resources and switches) or compile-time. I have had reports that that HP-UX 10.20 doesn't come with editres support so I added a standard work-around. HP-UX 10.20 users (and others without editres) should set mk-editres to no in the appropriate make/sys.*.mk file before compiling.
• One more little makefile hack for FreeBSD. Thanks to Brian Handy for the patch.
• Added the Back and Forward entries to the popup menu. These additions were based on a suggestion from Erik Luijten.
• Added the ability to read a PostScript file from the standard input. You can save the standard input to a temporary file (this gives you full page navigation) or just read it as it comes in. Thanks to David Green for this suggestion.
• Increased the optimization level to -O2 on all platforms. I don't think this will cause any problems.
• Finally fixed the current page not visible in the page list bug. You used to be able to move the selected item in the page list out of the visible range (i.e. if you're page list had room for ten items and you moved to page eleven with PageDown, the eleven in the page list wouldn't be visible).
• Added support for compressing, gzipping, and bzip2ing saved files. This was a quick and simple addition so I added it even though it has dubious utility.
• Merged the Mark|Mark Current Page and Mark|Unmark Current Page menu items. The new entry (Mark|Mark/Unmark) toggles the state of the current page.
• Changed the behavior of the Mark|Mark Even Pages and Mark|Mark Odd Pages menu items so that they no longer unmark any pages. Mark Even used to mark the even pages and unmark the odd pages, now it just marks the even pages and leaves the odd pages alone. Similarly, the Mark Odd command no longer unmarks the even pages.
• Some minor hacks for RedHat 5.0 systems. There are still some outstanding linking problems (no surprises here) with commercial Motif libraries; LessTif should work though.
• Added "-W" to the compiler warning flags for all gcc setups. This gives even more warnings the "-Wall -Werror -ansi -pedantic -Wmissing-prototypes" and this is good.
• Disabled gadgets when compiling with LessTif. I only use gadgets to allow people to use funky background pixmaps with Motif 2.0+ so disabling gadgets really doesn't hurt anything (disabling gadgets was a simple, clean, isolated hack to wlib/create.c so it doesn't hurt me either).
• Updated the LessTif Problems section again.
• Fixed the error message when you try to open a non-existent file; mgv was using EPERM instead of errno so the message wasn't always accurate.
• Loosened up the DSC checks. As long as the PostScript document begins with "%!" we'll scan for the structure comments. DSC documents are supposed to start with "%!PS-Adobe-" and a version number but there are some naughty PostScript files out there.
• Fixed a couple of typos in wlib/wlib/dirtysocks.h that were causing problems on Sun machines with Sun's compiler. Thanks go to Jean-Jacques Moulis for letting me know about the problem.
• Added a warning message about unknown switches. mgv used to try to open unknown switches as PostScript files but now it ignores such things. As a side effect you'll have to do one of the standard Unix tricks (end the switches with "--" or use "./-blah") to open files which begin with a hyphen from the command line. Thanks to David Green for this suggestion.
• I've changed ISPs once again so all references to echo-on.net have been converted to the new and improved trends.net.
• Added the Document Info dialog.
• Added the splash screen. If you don't like my artwork, you're free to use your own by replacing the splash.xpm and/or splash.xbm files in the final library directory. If you don't like splash screens at all, use the -nosplash switch or set the "mgv*wlShowSplashScreen" resource to False.
• Added support for sticky dialogs. Some people don't like it when dialogs popdown just because you've hit OK (or equivalent). See the autoDismiss resource and the Sticky Dialogs section for more information. This only affects the File Save, Print, and Set Magstep dialogs. This functionality is based on a suggestion from Carl Benker.

28.14 mgv 2.3.1: February 1998

• Modified the makefiles to know about and use ranlib if necessary. As far as I know, only FreeBSD (version 2.X at least) needs ranlib. This change also has the bonus side effect of allowing "make -j" to be used in the wlib directory (this may not matter to you but it is a big win on my K6-200); the only disadvantage is a slight increase in disk space when you're compiling.

28.15 mgv 2.3: February 1998

• Added a work-around for a bug in Motif 1.2.3. If you moved one of the main scrollbars out of the default position and left it out of the default position, a File|Close would cause a segmentation fault deep inside Motif. The problem was that mgv was trying to move the scrollbars in a widget that was in the process of dying, newer versions of Motif don't mind this but 1.2.3 was missing a check for this state. Some versions of Motif 1.2.5 also appear to have this problem.
• Updated the LessTif Problems section; mgv and LessTif; almost get along perfectly now.
• Added the gunzip and bunzip resources. These resources replace the decompress resource but decompress remains as an alias for gunzip. These changes were made so that mgv could deal with bzip2ed files, bzip2 is much slower than gzip but offers better compression on many files. You can get bzip2 from the bzip2 homepage or the bzip2 US mirror; you can also get bzip2 anywhere that you can get the Gimp.
• The resetScrollBars resource has been expanded to offer control over the horizontal and vertical scrollbars separately; this just means that you can have only the vertical scrollbar reset on page changes if you want. The old boolean values, true and false, have been retained as aliases. Thanks to Dmitri Kulginov for this feature.
• Page list updates (during Mark All and Show Page Labels for example) should be much faster now.
• Added -D_XOPEN_SOURCE_EXTENDED to the compiler flags for AIX. I hear that AIX 4.3 needs this rather than -D_XOPEN_SOURCE so I'll try it out with both defined and hope for the best (will the madness of -D_POSIX_SOURCE, -D_XOPEN_SOURCE, -D_BSD_SOURCE, etc... ever end?). Thanks to Lukasz Dutkiewicz for telling me about this new piece of vendor/standards brilliance.

28.16 mgv 2.2.1: December 1997

• Fixed a buffer overflow problem in the printing. The bug was a really dumb mistake, sorry for the brain damage.

28.17 mgv 2.2: November 1997

• Added support for non-default color depths, non-default visuals, and private color maps. This didn't have that much impact on the application but it is a cool enough increase in functionality to warrant an increase in the minor version number rather than just the patch level. Thanks to Hans Vahlenkamp for hassling me about this lacking feature (okay, hassling is probably a little strong).
• Fixed a bug in zoom window destruction. If you zoomed on a zoom and killed the first zoom before the zoomed zoom, you used to get death but now you don't.
• Fixed the menu accelerators to avoid duplication; the following accelerators were changed:
  • The Magstep menu is now activated with Alt+T instead of Alt+G.
  • The Options menu is now activated with Alt+S instead of Alt+O (this was taken).
  • The Set entry in the Magstep menu no longer has an accelerator, I couldn't think of anything sensible that wasn't already taken by something that gets more use.
  • The Enable Smooth Scrolling entry in the Options menu is now activated with Alt+L instead of the old Alt+O.
  If anyone doesn't like this, you can change them through the resource database to whatever you want.
• Fixed up the code that deals with (depth one) bitmaps for icons. The old code was causing a BadMatch error on some systems because a copy was attempted from a depth one Pixmap to a Window with a different depth.
• Added the wlUseColorIcon resource so you can tell mgv to use or not use a color icon at run-time.
• Fixed the spelling of Matthew's name in various places (I thought there was only one "t").
• Added a couple of minor (and harmless) changes to the resources for LessTif. These changes don't affect Motif versions of mgv.
• Added some notes on the Ghostview widget resources to the Application Resources section of the manual. I was sure the resources were already listed but I was wrong.
• Added the -portrait, -landscape, -seascape, and -upsidedown switches to control the initial page orientation.
• Extended the FreeBSD 2.2.2 support to deal with FreeBSD 3 with Motif 1.2.

28.18 mgv 2.1: October 1997

• Reversed the order of History list.
• Removed the Printer Name text field from the print dialog. The print command now holds both the command to use and the printer name. The resources (printer and printCommand are still separate, you can forget about printer and put it all in printCommand if you want).
• Fixed the GhostviewSendPS prototype. The old prototype had a long where it should have had an off_t. Apparently HP-UX 10.20's off_t isn't a long like it is on all the other machines (otherwise the compilers would have complained long ago). This was reported and fixed by Karl Storck.
• Small fixes to the makefiles and dirtysocks.h for Solaris 2.6/Intel. Thanks to Thanh Ma for the patch.
• I've changed ISPs once again (I'm on my third one this year), lglobal.com just got swallowed by echo-on.net so I've updated everything for this. I think it is time I forked out the cash for a virtual host somewhere.
• Some minor hacks were added to allow mgv and LessTif to get along a little better. There are still a number of problems with using LessTif but most things work. I've only tested things with the lesstif-current from 1997-10-02 so the current release might still be broken. You might also want to check my homepage for any updates on mgv and LessTif.
• A preliminary port to FreeBSD 2.2.2 was supplied by Christopher Yoder. The initial attempt was done with LessTif so I don't know how well this works yet (I don't expect any problems).

28.19 mgv 2.0.2: August 1997

• Always scroll the scrolled window back to the top when closing a file. Sometimes the scrolled window would get confused about where its child was when opening a new file; this only appears to happen if you are scrolled down near the bottom and then you open a new file in the same window. The confusion only happens with some files (the exact conditions are unknown but this scrolling-back-to-the-top trick makes the problem go away).

28.20 mgv 2.0.1: August 1997

• Fixed an auto-sizing bug. Any auto-sizing will now take effect if you hide the page list, menubar, or status line.
• Trying to open a non-existent file from the command line will now produce a warning message. Doing "mgv not-there.ps" used to just give an empty window.

28.21 mgv 2.0: August 1997

• Help system extended to deal with Netscape's remote protocol and Mosaic's CCI protocol. CDE help, and SGI help are still coming. The helpSuffix resource has been replaced with helpType.
• Added palette changing menu items.
• Changed the float resources in the Ghostview widget to integers to avoid alignment problems on the DEC Alpha (unaligned access).
• Freeing unallocated memory bugs in Ghostview.c fixed (some resources were getting copied by SetValues() and freed by Destroy() but not copied by Initialize()). These bugs were caused by some modifications that I made to the Ghostview widget. All of the String resources for the Ghostview widget are now copied as God intended them to be.
• You can now save a document without marking pages.
• Fixed two orientation bugs so that you no longer get forced back to the first page when changing orientation and changing the orientation from the menus will always work (in some cases, mgv would switch to the orientation in the document when you tried to change orientations).
• Added a ghost to the icon (hey, this is reason enough to upgrade isn't it?).
• Added the mgvMark action to the page list to make marking pages easier (maybe).
• Cleaned up the keyboard handling in the main viewing window so that the cursor keys do the right thing; the new mgvScroll action was added to facilitate this.
• Support for multiple top level windows added.
• On-the-fly decompression of compressed files added.
• All dialogs now make use of the defaultButton and cancelButton resources for better compliance with the Motif Style Guide. The zooming is now attached to mouse button one (used to be button two but Motif wants button two for drag-and-drop operations). If you want the old bindings back you just have to change the baseTranslations for the Ghostview widget to:

          MGv*Ghostview.baseTranslations: #replace         \n\
                  <Key>osfHelp:        wlHelpContext()          \n\
                  <Message>:   gvMessage()              \n\
                  !<Btn2Down>: mgvZoom(begin)           \n\
                  !<Btn2Motion>:       mgvZoom(extend)          \n\
                  !<Btn2Up>:   mgvZoom(end)             \n\
                  !<Btn1Down>: mgvZoom(begin)           \n\
                  !<Btn1Motion>:       mgvZoom(extend)          \n\
                  !<Btn1Up>:   mgvZoom(end)             \n\
                  <EnterWindow>:       gvNotify(0)              \n\
                  <LeaveWindow>:       gvNotify(0)              \n\
                  <MotionNotify>:      gvNotify(0)              \n\
                  <Key>osfUp:  mgvScroll(up,   magical) \n\
                  <Key>osfDown:        mgvScroll(down, magical) \n\
                  <Key>osfLeft:        mgvScroll(left)          \n\
                  <Key>osfRight:       mgvScroll(right)
          
  

  These bindings will give you zooming with either button one or button two.
• Added the magic scrolling based on a suggestion and patch from Brian Dowling. This introduced the magicScrolling and magicResistance resources.
• Modified the magstep menu based on a suggestion and patch from Brian Dowling. The old magstep menu let you choose from -5 through +5, the new one lets you increase and decrease it as desired.
• Added the Auto Size, Auto Height, and Auto Width buttons to the Page menu; the autoHeight and autoWidth application resources were also added. Thanks go to Brian Dowling for suggesting this.
• Added MP-RAS support to the makefiles.
• Added some screen shots to the documentation.
• The Reopen command will now try and reset the page number.
• Added support for libhelp online help (see http://www.informatik.uni-stuttgart.de/ipvr/bv/personen/mache/libhelp for the libhelp sources).
• Added smooth scrolling options.
• Added the magstep resource and the -magstep switch to make setting the initial magstep easier. Andy Polyakov pointed out this feature that got lost between Ghostview and mgv.
• Put the quick access -5 through +5 magstep entries back on the Magstep menu (a user thought all the clicking and typing and screen re-drawing was inconvenient and since I agreed, I put the radio buttons back). Erik Luijten liked the old -5 through +5 options so they came back.
• Made explicit page orientations persist through reopens. Credit for this behavior belongs to Erik Luijten.
• Hacked the new auto sizing stuff to, optionally, stay within the screen dimensions. I think mwm does this for us but mwm is an evil window manager (if you like mwm, go ahead and disagree with me, or kill me, or not). Since there is no sane way to determine how large the window manager decorations are, the wmWidth and wmHeight resources were added so you can tell mgv how big they are (you may notice that Ghostview uses pretty much the same hack). Added the -smartsizing, -wmwidth, and -wmheight switches to control these settings from the command line. I also added the Enable Smart Sizing button to the Options menu. This stuff was based on a suggestion from Andy Polyakov.
• Added the applicationVersion resource to help detect app-defaults files with the wrong version. I also expanded the installation documentation to cover this situation. This stuff was added based on problems experienced by Erik Luijten. After adding this, I moved it to wlib since it was too useful to duplicate in my other (as yet unpublished) projects.
• The Close All Zooms entry in the Window menu is now only sensitive if there are zoom windows.
• Change the default dirMask of the file-open dialog to *.*ps* (it was *.ps and then *.ps* to get gzipped/compressed files) to try and pick up .eps files too.
• Converted the menu bar widget tree to the standard (and highly idiotic, nonsensical, brain damaged, ...) Motif way. This allows mgv to work better with Motif 2.0.0 and perhaps some other old versions of Motif (Motif 1.2.2 on AIX 3.2.5 is one of them).
• Keyboard scrolling (the mgvScroll() action) cleaned up. I added the scrollPercentage resource to let users decide how much of the screen should be scrolled (the default of 90% yields a little bit of overlap for context). This little change should make scrolling (including the smooth kind) nicer.
• Fixed Mosaic-cci help. This got broken sometime (I don't know when since I almost never use this). The CCI stuff was trying to get a hostname out of "file:///path/to/x/blah.html" without realizing that file:// means localhost.
• Lots of internal changes that shouldn't be visible to the user.

28.22 mgv 1.0: September 1996

• First release.
