[c5c522c]1This is the latest version of the XV jumbo patches I originally created in
2February 2000 (but never distributed) and eventually updated and released in
3May 2004, prompted by a discussion on LWN (http://lwn.net/Articles/76391/).
4Information about the patches, updates to the patches, and the patches
5themselves can all be found here:

13These patches incorporate all of the fix- and enhancement-patches available
14from John's XV site (http://www.trilon.com/xv/downloads.html and
15ftp://ftp.trilon.com/pub/xv/patches/), plus a number of my own fixes and
16additions (security-related and otherwise), plus quite a few from other
17people.  They're still not fully complete, and it's probable they never
18will be, but I do plan to continue tinkering with them whenever the mood
19strikes--and I may even release them publicly on rare occasions.  (At the
20current rate, once every few years may be the best we can hope for....)
21
22Also be aware that several other people have had the same idea over the
23years.  Ones I've found, more or less by accident, include:

46This is not an exhaustive list (e.g., Jörgen Grahn also had one).  So far,
47most of the other patch-sets appear not to be as extensive or as up-to-date
48as my own, particularly now that the (very large) "Japanese extension" patches
49are incorporated--big thanks to Werner Fink of SuSE for that!
50
51Below I summarize the component patches that are encompassed by my jumbo
52bugfixes and jumbo enhancements patches, circa 2005.  (As of 2007, they're
53distributed as a single monster-patch, and the "component patches" are now
54listed in the changelog section at the bottom of this file.)  Unfortunately,
55some of my own additions never saw the light of day as standalone patches,
56but considering the number of overlaps (collisions) already implicit in the
57list, that would have been difficult to accomplish even if I'd had the time.

103patches (e.g., the jp-extension patches or within the PNG patch).
104
105Finally, please note that these patches have not been blessed by John Bradley
106in any way (although I copied him on the May 2004 announcement and wrote to
107him again in May 2005), unless you count Debian's redistribution permission
108(Daniel Kirchheimer, 5 Dec 2005).  Nor have I personally tested every change
109and feature!  (See the BIG SCARY WARNING below for further caveats.)  In other
110words, they're both completely unofficial and completely unguaranteed.  But
111they seem to work for me.  (And when they don't, I try to fix 'em--eventually,
112anyway... ;-) )

118How to build
119------------
120
121The following assumes you, the user, already have the libtiff,[1] libjpeg,[2]
122libpng,[3] zlib,[4] and JasPer[5] libraries downloaded, patched (if necessary),
123compiled, and installed, not to mention a C compiler and the bzip2,[6] tar,[7]
124patch,[8] and make[9] utilities.  You should also have downloaded the original
125XV 3.10a source distribution from the XV Downloads page[10] and be able to edit
126its Makefile and config.h files as indicated in the INSTALL file.  (Editing
127the Makefile will also allow you to disable some of the third-party libraries
128if you wish.)  Finally, you should know what a Unix(-style) command line is,
129where to find one, and how to wield it with abandon (or at least with adult
130supervision)--and preferably not as the root user until the "make install"
131step.  (A filesystem is a terrible thing to waste.)

146|                            BIG SCARY WARNING                            |
147|                                                                         |
148|  These patches work for Greg (and parts of them reportedly work for     |
149|  various other people), and so far Greg's CPU still computes and his    |
150|  hard disks haven't been wiped.  But there's no guarantee that this     |
151|  will be the case for you! In particular, not every incorporated patch  |
152|  has been explicitly tested, nor has every possible subcase of the      |
153|  explicitly tested subset. (Read that again; it's grammatical.)  Nor    |
154|  are these patches officially blessed by John Bradley in any way. In    |
155|  other words, if you use these patches, you do so at your own risk.     |
156|  (Greg doesn't believe there are any serious problems remaining, but    |
157|  then, what programmer ever does? Bugs happen.)                         |
158|                                                                         |

161Assuming you have the prerequisites out of the way and aren't scared
162off by the Big Scary Warning, here's the build procedure:
163
164      tar xvzf xv-3.10a-jumbo-patches-20070520.tar.gz
165      (or:  gzip -dc xv-3.10a-jumbo-patches-20070520.tar.gz | tar xvf - )
166
167      tar xvzf xv-3.10a.tar.gz
168
169      cd xv-3.10a
170
171      patch -p1 < ../xv-3.10a-jumbo-fix-enh-patch-20070520.txt
172
173      edit Makefile and config.h as directed in INSTALL file (in particular,
174      ensure paths to external libraries and header files are correct)
175
176      make
177
178      ./xv  your_favorite_image  your_other_favorite_image  etc.
179
180If everything seems to be working to your satisfaction, go ahead and install:
181
182      make -n install (and double-check that things will be installed
183      where you want them to be)
184
185      become root if necessary (e.g., type su)
186
187      make install
188      (or:  sudo make install)
189
190That wasn't so hard, was it?

308
309[!] Note that all six of these formats may still suffer from exploitable heap
310    overflows [*SECURITY*] when decoding images with large (possibly invalid)
311    dimensions; as a result, they are DISABLED by default.  (Search for "GRR
312    POSSIBLE OVERFLOW / FIXME" comments in xvmag.c, xvmaki.c, xvpi.c, xvpic.c,
313    xvpic2.c, and xvhips.c, but keep in mind that these may not be exhaustive.)
314    Users who choose to overlook these security issues can enable any or all
315    of them by editing config.h.
