I think deltarpm's zlib patch to support 'gzip --rsyncable' is
different to the rsync patch. I've sent the patch upstream in 2005,
but got no response.
(The original --rsyncable patch was done by Rusty Russell in 2002, btw)

So... that means the custom zlib isn't necessary to the proper operation

1) Reading the existing rpm -- this should work with vanilla zlib as well
2) Compressing the deltarpm -- this should work with vanilla zlib, just
not be as kind to rsync.
No, things are a bit different. Fedora's rpm used to have a
modified copy of zlib so that the created rpms were more rsync
friendly. As deltarpm needs to recreate the same compressed
payload I also had to support this.
AFAIK the current rpm uses the system's zlib library, so the
deltarpm copy is also no longer needed for Fedora.

solv's kernel handling appears to behave a bit different than yum's
perhaps? I put the output here:

That's because the kernels aren't marked for multi-version installation.
libsatsolver supports this, but the little solv tool doesn't.

Libsatsolver is already a separate project. It also has some

how debian dependencies work).
This would be a pretty nifty tool in Fedora as well.

Well, it's just a library. Stuff like download progress bar, repository

solv is just a very small (2800 lines) and limited application to

Hmm, where's the source?
You can get the source rpm by searching for libsatsolver instead
of libsatsolver demo. The git repository is available via:
git://git.opensuse.org/projects/zypp/sat-solver.git
but we're probably moving over to gitorious.org.

By coincidence I stumbled over the same bug yesterday. The
repository code could not handle repositories where the filelist
contains no absolute files. This was the case for kde-testing-all,
as it contains only src rpms. Now fixed.
I also fixed the no repomd.xml file bug, it didn't occur to
me that the mirrorlist/metalink responses can also contain yum's
$releasever/$basearch macros. Solv now supports this.
The RPM depends on gpg2 - which I --nodeps'ed away. I have gnupg2 -
assuming that's the same?
Me bad, gpg2 is the suse name. I now use gnupg2 when building
for fedora. Version 0.14.4 should have all fixes.
Thanks for testing!

I doubt that. It's not an easy task to create software as slow
as the 10.x update stack ;-)
ISTR that SUSE was rather infamous for
very slow package manager performance before zypper came along.
To clarify: this has nothing to do with zypper. Both zypper and
YaST use libzypp, which was pretty much unusable in the 10.x
SUSE releases. That's what prompted me to create the libsatsolver
library, now used by libzypp. Thus, both zypper and YaST are fast.
(PackageKit also uses libzypp, btw.)
Using the same library has the big advantage that you get the same
results (and bugs) using all interfaces.

Michael.

Tested. Works with mirror lists atleast partially but still too slow. I
have compared it with yum
some points:
- seems like it still accesses some remote hosts
because it checks if the metadata is up-to-date. It shouldn't
do this the second time you call it, seems like it doesn't
have write access to /var/cache/solv. Please chown the directory
to your uid.
- FL access is slowing it down a bit (FL is the complete filelist).
Even worse is that it had to download the file list for the
chromium repository every time because of the missing write
access.
- Also, I've rewritten the file provides algorithm, so it should
be quite a bit faster now (packages available in an hour). It
now rewrites the cache file after the file provides have been
added.
$ echo n | ( time ./solv up )
rpm database: cached
repo 'fedora': cached
repo 'rpmfusion-free': cached
repo 'rpmfusion-free-updates': cached
repo 'updates': cached
Transaction summary:
73 upgraded packages:
[...]
install size change: -8008 K
OK to continue (y/n)? Abort.
0.248u 0.052s 0:00.32 90.6% 0+0k 0+0io 0pf+0w
As you can see, if the solv can take full advantage of the
cache (no FL loads), it's pretty fast.
But this really isn't about execution speed, but correctness
of the solver results.

Michael.

There's no real goal, I'm just trying to make the library as

So, if you have some spare time, could you give it a try and tell
me where it works well/ does stupid things/ doesn't work at all?
On Fedora 11 (x86_32)
$ sudo solv info coreutils. Keeping reading some of the metadata over
and over again instead of caching them it seems.
It doesn't cache them if it encountered errors.
It also reads the xml
files instead of sqlite databases supported more recently.
Yes, it doesn't make sense to support those, as libsatsolver doesn't
use sqlite.
Also claims
some of the repos don't have repomd.xml file while they do
http://fpaste.org/paste/20055
download error 6 means that curl exited with exit code 6, which
means Couldn't resolve host according to the man page. That's
pretty strange, because downloading repomd.xml seems to have worked,
but primary.xml.gz suddenly fails.
rpmfusion-free: is the repo configured to use a mirrorlist instead
of metalink? That's not supported yet. Should be easy to add, though.
$ sudo solv search quake3
returns nothing after reading some of the repos again for quite
sometime. Ping me in irc if you need to test specific commands more. I
am mether in freenode and usually in #fedora-devel
Probably because it couldn't read the primary.xml file because of
the download error 6 problem.
Thanks for testing!

Testing libsatsolver on Fedora
Hi folks,
I'm the author of the libsatsolver library, a library solves
package dependencies with a SAT algorithm.
This library is currently used in SUSE by YaST/zypp. I'm currently
trying to make it less SUSE specific like adding support for package
coloring and different repo handling, but I'm pretty sure I didn't
catch all things where Fedora is different from SUSE.
To test things I've written a small application called solv that
works like a very tiny package manager. It's available via:
http://software.opensuse.org/search?baseproject=Fedora:11q=libsatsolver-demo
(To get the src rpm search for libsatsolver)
The package contains just a single file, /usr/bin/solv. It can
be run as normal user, but then the transaction can't be commited.
Also, the repository metadata caching mechanism needs write access
to /var/cache/solv. If it can't write there, it still works but
downloads the metadata again every time it is called.
So, if you have some spare time, could you give it a try and tell
me where it works well/ does stupid things/ doesn't work at all?
Thanks,
Michael.
