./xdelta test hang in mac os x 10.4

Fergus — Wed, 13 Dec 2006 13:45:57 -0000

Have not tried other versions of mac os but it after a straight forward "make" I ran "xdelta test". It hung at the "source_decompression" step. A half hour or so later I aborted the test.

xdelta does not work on 64 bit CPUs

A C G Mennucc — Wed, 21 Jun 2006 10:38:22 -0000

in Debian Bug
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=147187
it is shown that 'xdelta' does not work correctly
on 64 bit systems.

I am working on 'debdelta' , a program
to compute delta of .deb packages. More info in
http://tonelli.sns.it/pub/mennucc1/debdelta/

Debdelta is just a wrapper that analyzes the
.deb files and prepares chunks of data to pass to
a backend; the backend may be any binary
delta difference compressor program.

As you see from that web page, I evaluated many
backends; it turns out that 'xdelta'
is one of the best choices.

So I am very interested in solving this bug.

Any help appreciated.

XD3 assertion failed

A C G Mennucc — Thu, 15 Jun 2006 08:13:11 -0000

the command

$ ./xdelta3 -s old_file new_file >/dev/null

fails with error

xdelta3.c:2979: XD3 assertion failed:
stream->unencoded_offset == inst->pos
Aborted

The command
$ ./xdelta3-O -s old_file new_file /tmp/x
does not fail, but
$ ./xdelta3-O -d -s old_file /tmp/x /tmp/new_file
fails and reports:
xdelta3: target window checksum mismatch: Invalid argument

----

my OS is Debian unstable;
$ gcc --version
gcc (GCC) 4.1.2 20060604 (prerelease) (Debian 4.1.1-2)

note that gcc reports a lot of warnings such as
"warning: pointer targets ... differ in signedness"
and
"warning: dereferencing type-punned pointer will break
strict-aliasing rules"
and
"warning: ... may be used uninitialized in this fun"

look into

xdelta3.c:2979: XD3 assertion failed

Anonymous — Thu, 06 Apr 2006 00:02:26 -0000

Hello,

I am trying to use xdelta3 to keep some rather large
files in-sync remotely by shiping the diff. The Source
and Target are in the 17GB range. After 71 minutes I
recieve a:

xdelta3.c:2979: XD3 assertion failed:
stream->unencoded_offset == inst->pos

Previous to this, I do recieve warnings along the lines of:

xdelta3: warning: target window 23493 did not copy
source: 262144 bytes, 17164773376 source size

Any idea's?

Thanks for your time!

xdelta ignores --maxmem

Anonymous — Thu, 08 Sep 2005 13:49:21 -0000

xdelta ignores the --maxmem option.

Version-Release number of selected component (if
applicable):
1.1.3

How Reproducible:
100%

Steps to Reproduce:
1. xdelta delta --maxmem=16M largefile1 largefile2
deltafile
2. See how much memory it's taking.

Actual Results:
It takes more than 16M.

Expected Results:
It takes at most 16M.

xdelta-1.1.3: Return value of successful delta not 0

Tomasz Ostrowski — Wed, 03 Dec 2003 11:42:39 -0000

I have written a script which is using xdelta to make
differential backups. And I've came up with a problem
that xdelta returns 1 on success, not 0. Most programs
return 0 - so it is easy to check if everything went OK
with something like:
program args || exit -1
with sh.

Also if xdelta will be used in cron it will report that
there was an error. And many other utilities.

Why Xdelta Fails in case of requestID 663268

vivek jain — Thu, 19 Jun 2003 12:22:31 -0000

The Xdelta checks that the files supplied for the delta
are gzipped or not. The xdelta exe does this by checking
the first two bytes of the files. If the first byte is octal
37 and second byte is octal 213 it assumes that the files
are gzipped. The file submitted by Safari conains first
two bytes as these. Hence xdelta assumes that these
are gzipped and produces the patch accordingly which is
not the case.
