Embeddable CouchDB

[Zdravko Gligic <zg...@gmail.com>]

Folks,

I am building an Adobe AIR application and it really hurts even to
think about using its embedded SQLite, instead of CouchDB because of
the app's need for client/server replication. Then I read how CouchDB
is avilable on Android and mobile devices and right of simplicity of
installation comes to mind - being deployed to such non geekish
masses.  Then I read something about Jan's CouchDBX.

So, just how difficult would it be to come up with a set of command
prompt runnable utilities that I could invoke from Adobe AIR or any
desktop application, that would kickstart an install of CouchDB if it
is not already installed and then would start whatever [service]
processes are required to keep it running and usable from my AIR app ?

Can CouchDB be installed to any Windows folder?
Are there any registries or anything else that is updated?
What about Erlang and its installation?
What else is happening in current CouchOne binary install?

Thanks a log,
Teslan

The current size of the android build is 4.2MB (that includes erlang,
spidermonkey and couch, but not icu) so building an installer within
reasonable size limits should be possible.

its definitely something I want to look at but probably wont have time to
until the android build is finalised, I would also keep an eye on benoitc's
refuge project as he has said that is also a goal

Cheers

Hi Teslan/Dave,

Thanks for starting this thread. I am also working on creating an AIR app which 
has a strong need for online/offline synchronization. I want to create a 
standalone AIR installer, which installs the app as well as couch DB all in one 
go...without bothering the end user. Now, I still need to identify how I am I 
going to do this, but I guess I can use things like Install Jammer for creating 
the complete package. But my key concern is that if I bundle couchDB installer 
along with the app installer, then does it greatly increases the size of the 
installer? (just comparing with SQLite DB.....the job is quite easy there....but 
I miss out on all the power of shared database that couch DB provides).

Hi Teslan,
If there is a sample app that you have already created, would you mind sharing 
it? Also, if you have been able to establish a process, can you please 
share that as well? It would greatly help.

Hi Teslan

I can't answer your other questions but for CouchDB install on
windows. Let me know if you need more info.

> Can CouchDB be installed to any Windows folder?

- yes it can - there are silent install options using the inno5 installer
    http://www.jrsoftware.org/isinfo.php & http://www.jrsoftware.org/ishelp/
you'll end up with something like this:
setup.exe /silent /dir="c:\relaxing\folder"

caveats - if the Visual C++ runtime needs updating this might in some
cases require a reboot.

> Are there any registries or anything else that is updated?

there's no significant registry entries - just enough to drive the
uninstaller. All the later config settings happen in the couchdb ini
files in %installdir%\etc\couchdb\

If you install as a service then there are other requirements
obviously like any service you'll need to have sufficient permissions
to do so.

> What about Erlang and its installation?

ditto as above. The main thing is that erlang runs install.exe
post-install to ensure it is in the "right" directory - updating 2
copies (yup 2) of erl.ini.

> What else is happening in current CouchOne binary install?

I've not looked at this but I think the intent was to provide an
install that can be unpacked in your home folder & "just works". Let
us know what you find out when you try it.
