These are the latest versions of the XV jumbo patches I originally created
|
||
|
in February 2000 (but never distributed) and eventually updated and released
|
||
|
in May 2004, prompted by a discussion on LWN (http://lwn.net/Articles/76391/).
|
||
|
Information about the patches, updates to the patches, and the patches
|
||
|
themselves can all be found here:
|
||
|
|
||
|
http://pobox.com/~newt/greg_xv.html
|
||
|
http://freshmeat.net/projects/xvjumbopatches/
|
||
|
|
||
|
(Use the "Subscribe to new releases" link on the latter page if you want to
|
||
|
be notified of new versions automatically; trivial registration required.)
|
||
|
|
||
|
These two patches incorporate all of the fix- and enhancement-patches
|
||
|
available from John's XV site (http://www.trilon.com/xv/downloads.html
|
||
|
and ftp://ftp.trilon.com/pub/xv/patches/), plus a number of my own fixes
|
||
|
and additions, plus quite a few from other people--though not all of the
|
||
|
ones I'd intended to, due to lack of time after dealing with the latest
|
||
|
set of security issues (one of which I discovered, sigh). They're still
|
||
|
not fully complete, and it's possible they never will be, but I do plan
|
||
|
to continue tinkering with them whenever the mood strikes--and I may even
|
||
|
release them publicly on rare occasions. (At the current rate, it looks
|
||
|
like once a year may be the best we can hope for...we'll see.)
|
||
|
|
||
|
Also be aware that several other people have had the same idea over the
|
||
|
years. Ones I've found, more or less by accident, include:

I very much doubt that this is an exhaustive list. So far, most of the
|
||
|
other patch-sets appear not to be as extensive or as up-to-date as my own,
|
||
|
particularly now that the (very large) "Japanese extension" patches are
|
||
|
incorporated--big thanks to Werner Fink of SuSE for that!
|
||
|
|
||
|
Below I summarize the component patches that are encompassed by my jumbo
|
||
|
bugfixes and jumbo enhancements patches. Unfortunately, some of my own
|
||
|
additions never saw the light of day as standalone patches, but considering
|
||
|
the number of overlaps (collisions) already implicit in this list, it would
|
||
|
have been difficult to accomplish even if I'd had the time.
|
||
|

Other credits are as listed on the XV Downloads page or in the respective
|
||
|
patches (e.g., the jp-extension patches or within the PNG patch).
|
||
|
|
||
|
Finally, please note that these patches have not been blessed by John Bradley
|
||
|
in any way (although I copied him on the May 2004 announcement--no response
|
||
|
at that time). Nor have I personally tested every change and feature! (See
|
||
|
the BIG SCARY WARNING below for further caveats.) In other words, they're
|
||
|
both completely unofficial and completely unguaranteed. But they seem to
|
||
|
work for me. (And when they don't, I fix 'em. Eventually, anyway... ;-) )
|
||
|
|
||
|
One further "final" note: as of this release, I am no longer updating the
|
||
|
fixes patch; new stuff (including fixes) now appears only in the enhancements
|
||
|
one. It simply became too much of a timesink to maintain parallel trees--not
|
||
|
to mention parallel makefiles (generic/public vs. local/personal, old vs.
|
||
|
new libjpeg/libtiff) and xv.h (unregistered/public vs. registered/personal),
|
||
|
particularly when some fixes came about while working on an enhancement and
|
||
|
others were provided by third parties relative to the previous fix+enh state.
|
||
|
Hence the mismatched "20050410" date on the fixes patch.

How to build
|
||
|
------------
|
||
|
|
||
|
The following assumes you, the user, already have the libtiff,[1]
|
||
|
libjpeg,[2] libpng,[3] and zlib[4] libraries downloaded, patched (if
|
||
|
necessary), compiled, and installed, not to mention a C compiler and
|
||
|
the bzip2,[5] tar,[6] patch,[7] and make[8] utilities. You should also
|
||
|
have downloaded the original XV 3.10a source distribution from the XV
|
||
|
Downloads page[9] and be able to edit its Makefile and config.h files
|
||
|
as indicated in the INSTALL file. Finally, you should know what a
|
||
|
Unix(-style) command line is, where to find one, and how to wield it
|
||
|
with abandon (or at least with adult supervision)--and preferably not
|
||
|
as the root user until the make install step. (A filesystem is a
|
||
|
terrible thing to waste.)

|
| BIG SCARY WARNING |
|
||
|
| |
|
||
|
| These patches work for Greg (and parts of them apparently work for |
|
||
|
| various other people), and so far Greg's CPU still computes and his |
|
||
|
| hard disks haven't been wiped. But there's no guarantee that that |
|
||
|
| will be the case for you! In particular, not every incorporated patch |
|
||
|
| has been explicitly tested, nor has every possible subcase of the |
|
||
|
| explicitly tested subset. (Read that again; it's grammatical.) Nor are |
|
||
|
| these patches officially blessed by John Bradley in any way. In other |
|
||
|
| words, if you use these patches, you do so at your own risk. (Greg |
|
||
|
| doesn't believe there are any serious problems remaining, but then, |
|
||
|
| what programmer ever does? Bugs happen.) |
|
||
|
| |
|
||
|
+-------------------------------------------------------------------------+
|
||
|
|
||
|
Assuming you have the prerequisites out of the way and aren't scared
|
||
|
off by the Big Scary Warning, here's the build procedure:
|
||
|
|
||
|
bzip2 -dc xv-3.10a-jumbo-patches-20050501.tar.bz2 | tar xvf -
|
||
|
(or tar xvzf xv-3.10a-jumbo-patches-20050501.tar.gz)
|
||
|
|
||
|
tar xvzf xv-3.10a.tar.gz
|
||
|
|
||
|
cd xv-3.10a
|
||
|
|
||
|
patch -p1 < ../xv-3.10a-jumbo-fix-patch-20050410.txt
|
||
|
|
||
|
[optional] patch -p1 < ../xv-3.10a-jumbo-enh-patch-20050501.txt
|
||
|
|
||
|
edit Makefile and config.h as directed in INSTALL file (in particular,
|
||
|
ensure paths to external libraries and header files are correct)
|
||
|
|
||
|
make
|
||
|
|
||
|
./xv your_favorite_image your_other_favorite_image etc.
|
||
|
|
||
|
If everything seems to be working to your satisfaction, go ahead and install:
|
||
|
|
||
|
make -n install (and double-check that things will be installed
|
||
|
where you want them to be)
|
||
|
|
||
|
become root if necessary (e.g., type su)
|
||
|
|
||
|
make install
|
||
|
|
||
|
That wasn't so hard, was it?

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

not finished (and/or even started ;-) ):
|
||
|
|
||
|
- fix xvpng.c not to use direct struct access

||
|

|
||
|

||
|
- fix for spacebar-for-next-image getting stuck at first text file
|
||
|
- fix for .ppm.gz "disk leak" [can't reproduce...already fixed?]
|
||
|
(maybe occurs only if filesystem is already nearly full? bad .gz?)
|
||
|
|
||
|
- transparency support for TIFF, XPM and TGA images
