Version 0.2.6 on SVN can now run as a daemon and be controlled by command line or JSON-RPC.
On Linux it needs libgtk2.0-0 installed, but does not need a GUI running. Hopefully gtk can be installed without having a windowing system installed.
The command to start as a daemon is:
bitcoin -daemon [switches...]
Or, to run the UI normally and also be able to control it from command line or JSON-RPC, use the "-server" switch.
bitcoin -server [switches...]
With either switch, it runs an HTTP JSON-RPC server that accepts local socket connections on 127.0.0.1:8332. The port is bound to loopback and can only be accessed from the local machine, but from any account, not just the user it's running under.
To control it from the command line, the interface is a command name without any switches, followed by parameters if any.
bitcoin <command> [params...]
For example:
bitcoin getinfo
bitcoin getdifficulty
bitcoin setgenerate true
bitcoin stop
It's a simple JSON-RPC client and prints the JSON result. Look at rpc.cpp for the list of commands.
Web apps or anything automated will normally use JSON-RPC directly, not command line. There are JSON-RPC libraries for all the major languages. In script languages like PHP and Python the syntax is as natural as calling a local function.

Oh thank you!
You have no idea how badly I needed something like this.
I will have a payment library built in no time.

Will this requirement be removed sometime? I'd rather not have to deal with GTK.
Re: Command Line and JSON-RPC
Gtk is required by the GUI, so it must be linked if you want to use the same binary. Making a separate binary is another option, dunno how much code tweaking and ifdeffing that would take.

Re: Command Line and JSON-RPC
*NIX peoples are "purists" of sorts. They don't like to pollute their OS installs with libraries that shouldn't be necessary.
A million ifdefs are not the answer either. Hmm.. more thought to this may be required.

Re: Command Line and JSON-RPC
I'm using Linux From Scratch, so installing a dependency-ridden package like GTK would be a bit of a pain. Why should I add a dozen additional packages and hundreds of megabytes to my system when BitCoin doesn't even use them?
Re: Command Line and JSON-RPC
Why would you install them? Because you currently have to. I know the feeling. I run minimalist FreeBSD servers and to clutter them with X libraries is a pain.
However, installing them onto a X workstation is totally fine -- you usually have all of the correct dependancies already.

Re: Command Line and JSON-RPC
This is strange... When I start Bitcoin as a daemon on my 64 bit Linux server, it eats up all the 250MB of remaining RAM, 700MB of swap and eventually crashes. On my 32 bit Ubuntu desktop, it works fine and stays at 15MB of memory usage. The server is running a 64 bit build of Bitcoin. Maybe there's something wrong with the build or something.
Re: Command Line and JSON-RPC
When and how fast did memory usage increase? Right away, slowly over a long time, or starting at some later event?
I have -daemon running on ubuntu 9.10 64-bit and memory usage is steady.
It has to be something about the difference on the server besides 64-bit. Maybe some malfunction from the lack of GUI. A memory leak debug tool could give a clue.

Re: Command Line and JSON-RPC
It started increasing right away. I'll see if valgrind can help me.
Re: Command Line and JSON-RPC
OK, I made a build target bitcoind that only links wxBase and does not link GTK. Version 0.2.7 on SVN.
I split out the init and shutdown stuff from ui.cpp into init.cpp, so now ui.cpp is pure UI. ui.h provides inline stubs if wxUSE_GUI=0. We only have four functions that interface from the node to the UI. In the bitcoind build, we don't link ui.o or uibase.o.
Another way to debug would be to run in gdb, wait until everything is quiet and all threads should be idle, and break it and see which thread is busily doing something and what it's doing.
I suspect bitcoind will probably work fine, but I hope you can still debug the problem.

Sure feels like it could be something in wxWidgets retrying endlessly because some UI thing failed or something wasn't inited correctly. Our hack to ignore the initialize failure and run anyway means we're in uncharted territory. We're relying on the fact that we hardly use wx in this mode. We do still use a few things like wxGetTranslation and wxMutex.Another way to debug would be to run in gdb, wait until everything is quiet and all threads should be idle, and break it and see which thread is busily doing something and what it's doing.

Re: Command Line and JSON-RPC
I'm getting errors when trying to compile with just wxBase.
Clipbrd.h isn't installed with wxBase. Moving wxWidgets-2.9.0/include/wx/clipbrd.h to my include directory just eliminates those two "no such file" lines.
Code:

Re: Command Line and JSON-RPC
wx/clipbrd.h isn't used, move it inside the #if wxUSE_GUI.
Updated headers.h on SVN.
Sorry, I linked to wxbase but I had full wxWidgets on my computer.
The db.h:140 class Db no member named "exisits" is stranger. pdb->get, pdb->put, pdb->del compiled before that. Do you have version 4.7.25 of Berkeley DB?
Db::exists()

http://www.oracle.com/technology/documentation/berkeley-db/db/api_reference/CXX/dbexists.html
I suppose they might have added exists recently, using get before that.

I'm using Berkeley DB 4.5.20.

Using DB-4.7.25 fixed that problem.

Re: Command Line and JSON-RPC
Are you using wxWidgets 2.9.0? I don't recommend using anything other than 2.9.0.
It looks like they've got a reference in the wx headers (arrstr.h) to something outside of wxBase.
Removing -D__WXDEBUG__ from bitcoin's makefile would probably solve it.
If that doesn't work and you just want to get it working, you could edit wxWidgets include/wx/arrstr.h, line 167 and comment out the wxASSERT_MSG.

Re: Command Line and JSON-RPC
The headless mode is incredibly usefull. Finally I can start generating on my servers in the night
Re: Command Line and JSON-RPC
Cool; it works! Thanks for your help!
I am using 2.9.0.
(No memory issues for me.)

That wchar thing was what I was stuck on for the OSX build.
Glad to see it is ironed out. I'll keep hacking away now.

sirius-m debugged this, it was 64-bit related. The fix is now available on SVN, file util.cpp.
