Damn where is the error! In between I changed something that breaks the hole shit.

Code:
import portage_db_template
import os
import os.path
import cPickle
import cdb


class database(portage_db_template.database):

    def module_init(self):
        self.addList = {}
        self.delList = []
        self.modified = False
        self.cdbName = os.path.join(self.path, self.category) + ".cdb"
        self.cdbObject = None
        self.__openCDB()
       
    def has_key(self, key):
        self.check_key(key)
        retVal = 0

        if self.cdbObject.get(key) is not None:
            retVal = 1

        if self.modified:
            if key in self.delList:
                retVal = 0
            if key in self.addList:
                retVal = 1
           
        return retVal

    def keys(self):
        myKeys = self.cdbObject.keys()

        if self.modified:
            for k in self.delList:
                myKeys.remove(k)
            for k in self.addList.iterkeys():
                if k not in myKeys:

What's up now?
I'm waiting for a version that speeds up the sync and works when I want to merge something. :D

Look at the starting message. I've updated it to a version that works.

Hei
I have just followed the procedure on page one of this thread. I have no errors as such, but in /var/cache/edb/dep/usr/ I have /local/portage containing the .cdb files, ie not /portage ref your earlier comments.

I have the following results which look ok.
Code:
# time emerge metadata
skipping sync
>>> Updating Portage cache:  100%
real    0m40.862s
user    0m22.223s
sys     0m6.366s

Btw, I use the following in make.conf..
Code:
PORTDIR="/mnt/hdb9/portage"
DISTDIR="/mnt/hdb9/portage/distfiles"
PKGDIR="/mnt/hdb9/portage/packages"

regards

Edit: Its OK, I found the .cdb files in /var/cache/edb/dep/mnt/hdb9/portage!
Well, I assume its OK!?

seems to imply it can't find the module at all. have you checked the path and spelling and everything?

After creating /usr/lib/portage/pym/portage_db_cdb.py and dropping in the script, did you check if it was executable?

I got an amazing speed up.
Really great work. Hope you can
maintain it though.

Thanks a lot!

There should be no need to make the source file executable. But anyway it runs now :P ! Hope you like it all. Anybody knows to whom I have to talk to include it in portage? :twisted:

for first step, submit a bugreport explaining what your app does and attaching an ebuild
(and let us know the result, great extension!!)

IRC on to irc.freenode.org, and see what people in #gentoo-portage think of it.

So, I went to #gentoo-portage, and carpaski was nice enough to explain to me the issues with this module:
Code:
13:23 < chaosite> What do you guys think about this CDB-portage interface ... ?
13:23 < chaosite> http://forums.gentoo.org/viewtopic-t-261580-postdays-0-postorder-asc-start-0.html
13:24 <@carpaski> Constant DB ?
13:25 < chaosite> Dunno what it stands for...
13:25 < chaosite> It does have a webpage here: http://cr.yp.to/cdb.html
13:27 <@carpaski> cdb modules have been around a while...
13:27 <@carpaski> Someone hacked it in once...
13:27 <@carpaski> Didn't like that hack.
13:28 <@carpaski> First I've seen of an actual module for it though.
13:28 <@carpaski> Anything that relies on an external app that uses C calls is subject to Segfaults.
13:28 <@carpaski> This is why we don't use anydbm by default.
13:29 <@carpaski> flat and cpickle are python... So unless python explodes, portage works.
13:29 <@carpaski> Saves headaches.
13:29 < chaosite> So, basically, you're saying that this adds more runtime dependencies to portage, which might fail?
13:30 <@carpaski> Potentially, yep.
13:30 <@carpaski> If it works for you, great...
13:30 <@carpaski> But I wouldn't have any expectation of it being a default.
13:30 < chaosite> Alright.
13:31 <@carpaski> The major kicker is that segfaults outside of python segfault the entire process.
13:31 <@carpaski> Otherwise it wouldn't be a problem.
13:31 <@carpaski> Seeing this is really disturbing:
13:31 <@carpaski> emerge -e world
13:31 <@carpaski> Segmentation Fault
13:32 < chaosite> Yeah, that won't be any fun...
13:33 < chaosite> Mind if I post this to the forums?
13:33 <@carpaski> Have at it.
13:33 < chaosite> Thanks :)
13:33 <@carpaski> The module can circulate, no problem with that... it could even get included at some point.
13:33 <@carpaski> It just has pretty much no chance of being default.


So there :)

Sure, no problem :)

It would be great if you guys tried out the ebuild and said "This works for me" or something like that.

Question:
did
Code:
 time emerge --searchdesc mencode,
real: 1m16.127s
user: 0m20.659s
sys: 0m7.377s


would that thing here give me a speedup on AMD 2400XP+, 512MB RAM, complete Reiser4-Fs, pure udev?

Maybe.

Try it and tell us :wink:

It did give me a speedup on a Pentium 4, 512MB, /usr/portage on reiser4, and udev.

Well emerge metadata took
real 1m40
user 0m16
sys 0m9

the emerge --searchdesc mencode:
Code:
real 0m47.228s
user 0m29.326s
sys 0m4.086s


So well it did speed up a little ;) although emerge metadata was a bit slow.. mightbe that is because it was the first time i did it?

Code:
xBox xb0x # touch /usr/lib/portage/pym/portage_db_cdb.py
xBox xb0x # nano -w /usr/lib/portage/pym/portage_db_cdb.py  // <---pasted the script
xBox xb0x # touch /etc/portage/modules
xBox xb0x # nano -w /etc/portage/modules // <---pasted the script
xBox xb0x # env-update
Traceback (most recent call last):

SyntaxError: invalid syntax

-rw-r--r-- 1 root root 5698 Mar 9 12:52 portage_db_cdb.py
Code:
Portage 2.0.51.19 (default-linux/x86/2004.3, gcc-3.4.3-20050110, glibc-2.3.4.20050125-r0, 2.6.11-nitro0 i686)
