Hmm, now that I got this far I do bother :)

Okay, I figured it out! Not sure how the Tests/ directory would matter.
The tarball has a top-level directory of xmlconf/ inside. And something
in runxmlconf.exe is looking for this directory. The directory tree I
used is as follows:

$ cd /usr/local/src/libxml2/libxml2-2.8.0/xstc
$ ls -1F
Makefile
Makefile.am
Makefile.in
runxmlconf.log
runxmlconf.zip
xmlconf/
xmlts20080827.tar.gz
xmlts20080827.txt
xstc.py*
xstc-to-python.xsl*

$ ls -1F xmlconf/ # contents of the tarball
eduni/
files/
ibm/
japanese/
oasis/
sun/
testcases.dtd*
xmlconf.xml*
xmltest/

I then called the testsuite from inside xstc/ :

Re: Release candidate 1 of libxml2 2.8.0

Daniel Veillard — 2012-05-16T15:20:28

  okay, that solves the problem :-)


  Just extract it under xstc I have:

paphio:~/XML -> ls xstc
fixup-tests.py  Makefile.in  xstc.pyc
xsts-2004-01-14.tar.gz
Makefile        Tests        xstc-to-python.xsl
Makefile.am     xstc.py      xsts-2002-01-16.tar.gz
paphio:~/XML -> 

  Tests was created by extracting xsts-2004-01-14.tar.gz tarball there.
then runxmlconf should just grab data from there, if that doesn't work
don't bother :-)

  thanks !

And it isn't any prettier on a UTF-8 terminal. I think it doesn't matter
because perl on Cygwin doesn't have EBCDIC either, so why should libxml?

  Thanks everybody for the set of tests feedback on the prerelease,
keep them coming :-) !


  okay,


  I would guess the ebcdic encoding support is limited, it would be
interesting to just try out for example 
   xmllint --encode UTF-8 test/ebcdic_566012.xml
and see if it outputs something okay or an error


  Hum, that's weird, the only thing I can think of is doing vaidity
  testing of XHTML which may load the DTDs, I have a local cache because
the XHTML1 DTDs are loaded in the XML catalog on my machines. I'm
surprizer because I sometimes run "make check" on machines without
any IP connection.


  it's a good thing to run runxmlconf but here it just relies on
2 tarballs installed under the xstc directory:
  xsts-2002-01-16.tar.gz and xsts-2004-01-14.tar.gz
I guess the later is actually used and extracted as a Tests/ subtree
under xstc. If needed I can put those 2 tarballs somewhere on
xmlsoft.org (and maybe change the test to load from there)

  thanks !

 Yes you should have libxml2-2.7.6-8.el6 or something close. This
 includes all the needed security patches on top of 2.7.6.

This tests gets firewalled by the W3.ORG servers, I checked using
netstat. So I interrupted it. The source file testapi.c is huge.
Is there an easy way to instruct the program not to go the W3.ORG
servers like with xmllint --nonet?

./testchar.exe - ok

./testdict.exe - ok

./runxmlconf.exe - http://www.w3.org/XML/Test/xmlts20080827.tar.gz

I didn't run this test suite. Would it matter running it on Cygwin?

not MSXML, which itself is already COM and available on Windows,

Hi Shultz,

RedHat packages libxml2, just run "yum info libxml2" and it will tell
you what version is available (for me I have libxml2 version 2.7.6),
and "yum install libxml2" will install it.

Release candidate 1 of libxml2 2.8.0

Daniel Veillard — 2012-05-15T12:48:12

  I finally managed to go though all the patches which accumulated in
Gnome bugzilla and do the various necessary cleanups to try to get a
release. There is however *many* changes, especially on the portability
side which I just can't test myself (including many changes on various
Windows toolchains). So I just made a release candidate of 2.8.0

   ftp://xmlsoft.org/libxml2/

look for libxml2-2.8.0-rc1.tar.gz, there is also rpms generated on my
Fedora 16 box for those interested.
The code seems to work okay, I have been running with the changes as
I added them and my system didn't blew up, it passes valgrind, there
doesn't seems to be leaks at least on the main paths, so I think it's
time for more general testing.
 Please give it a try, I will make other rc release if needed, and
will try to shoot for a final 2.8.0 release a week from now ! I know a
number of people waited for an official release, please help me finish
by testing it and report problems if you find some :-)

  thanks in advance,

Daniel

  Okay, great :-)

[PATCH] Use a hybrid allocation scheme in xmlNodeSetContent.

Conrad Irwin — 2012-05-13T08:46:08

Heh, I thought that too. Actually you're looking at the result with XML_ALLOC_EXACT! This
is because EXACT adds 10bytes "spare" on each alloc, and that interestingly wastes about the
same amount of space as XML_ALLOC_DOUBLEIT on this example (see below).

So it turns out that the default realloc() on my system actually handles this case really
well — and I guess that all the time in xmlRealloc() was actually in xmlStrlen, not the
underlying realloc() after all (sorry for misleading you). If you replace the realloc()
with a bad one (like valgrind's), then the performance degrades severely.

This patch implements a HYBRID allocator which has the behaviour you describe (it's
like EXACT to start with, though without the spare 10 bytes; and switches to DOUBLEIT
after 4kb) — that gets the memory back down to 12755657, with no noticeable impact on the
performance of the synthetic pathological example under valgrind.

In summary:

     max_memory on ./xmllint --noout doc/libxml2-api.xml,
     valgrind time on h
