Bug Description

Binary package hint: libreoffice

running this:

soffice "--accept=socket,host=localhost,port=2002;urp;"

and also this:

#!/usr/bin/python

import uno

class test():
    def __init__(self):
        localContext = uno.getComponentContext()
        resolver = localContext.ServiceManager.createInstanceWithContext(
                        "com.sun.star.bridge.UnoUrlResolver", localContext )
        ctx = resolver.resolve(
"uno:socket,host=localhost,port=2002;urp;StarOffice.ComponentContext" )
        smgr = ctx.ServiceManager
        print 'smgr'
        desktop = smgr.createInstanceWithContext(
"com.sun.star.frame.Desktop",ctx)
        print 'desktop'
        model = desktop.getCurrentComponent()

vcl =
smgr.createInstance("com.sun.star.resource.VclStringResourceLoader")
print vcl
# vcl.setValue("FileName", "test")

if __name__ == "__main__":
print 'test'
test()

fails nastily :-) like this (different line numbers)

The basic problem seems to be (put a break in 'shutdown') that we close the connection while we would still rather be reading & writing to it ;-) - magically, from another thread; thus:

which occurs just before the main thread gets its answer back and we get the exception. That seems a bit enthusiastic of thread 4.

Do we -really- want to terminate the bridge after each 'run' call ? Surely we can re-use the socket.

238	void Bridge::terminate() {
239	    rtl::Reference< Reader > r;
240	    rtl::Reference< Writer > w;
241	    Listeners ls;
242	    {

244	        if (terminated_) {
(gdb) 
245	            return;
246	        }
247	        std::swap(reader_, r);
248	        std::swap(writer_, w);
249	        ls.swap(listeners_);
250	        terminated_ = true;
251	    }
252	    try {
253	        connection_->close();
254	    } catch (css::io::IOException & e) {

All looks most odd to me :-)

following the discussion at http://nabble.documentfoundation.org/python-XInvocation-snafu-td2961502.html I had a look at VclStringResourceLoader and it is broken beyond repair.

With commit
http://cgit.freedesktop.org/libreoffice/components/commit/?h=feature/gsoc2011_wizards&id=264c9ed93f3d338f6aee84310135569710705783

I removed the broken service and implemented a org.libreoffice.extensions.resource.ResourceStringIndexAccess service as a replacement.

Here is a piece of Basic code that shows how to use it (inspired by http://opengrok.libreoffice.org/xref/components/wizards/com/sun/star/wizards/common/TerminateWizardException.java ):

Sub Main
dim xSM
dim xContext
dim xRSIA as Object

dim aArgs(0)
aArgs(0) = "dbw"

xSM = GetProcessServiceManager()
xContext = xSM.DefaultContext
xRSIA = xSM.createInstanceWithArguments("org.libreoffice.resource.ResourceStringIndexAccess", aArgs)
msgbox xRSIA.getByIndex(1006)
end sub

I commited the change to the feature branch gsoc2011_wizards as this change would break master because I have not yet changed the clients of VclStringResourceLoader to use ResourceStringIndexAccess instead.

Because in some places also StringLists are needed as resources, I had to change the API has to take care of that too. Here is an updated example:

Sub Main

dim xStringIndexAccess as Object
dim xStringListIndexAcess as Object
dim pv() as Object

dim aArgs(0)
aArgs(0) = "svt"

xSM = GetProcessServiceManager()
xResourceIndexAccess = xSM.createInstanceWithArguments( _

xStringListIndexAccess = xResourceIndexAccess.getByName("StringList")
pv = xStringListIndexAccess.getByIndex(16633)
msgbox pv(0).Name
msgbox pv(0).Value
xStringIndexAccess = xResourceIndexAccess.getByName("String")
msgbox xStringIndexAccess.getByIndex(16390)
