Re: [equinox-dev] equinox bundle akin to felix fileinstall
The closest thing is the dropins support in p2, but that is not a good comparison since felix fileinstall is a small single bundle. p2 dropins support is just a part of the whole p2 engine and requires a fair bit of the p2 engine to function. I would be curious to know what exceptions you are seeing with felix.fileinstall. Perhaps it indicates an equinox framework bug we should fix. Please open a bug against Equinox-Framework if you think it could be. I would like to make sure the felix.fileinstall works on Equinox. Tom From: Raymond Auge raymond.a...@liferay.com To: Equinox development mailing list equinox-dev@eclipse.org, Date: 06/15/2012 08:32 AM Subject:[equinox-dev] equinox bundle akin to felix fileinstall Is there such a project? I'm having issues with felix.fileinstall on equinox (exceptions on change state) and wondering if I can save myself the trouble if there is a more native implementation similar to it.

Re: [equinox-dev] equinox bundle akin to felix fileinstall
I think it's more likely that FileInstall is seeing the file and trying to install it while the external process (whatever that might be) is still writing it to the disk. Short of hooking into the OS filesystem events (which would require platform-specific native code), any Fileinstall-like bundle will have the same problem. To alleviate this problem, FileInstall has a configurable timer, i.e. it will only look at the file if it stops changing for a period of time. Maybe you just need to increase the length of that timer. Unfortunately I don't recall exactly how to do that.

separate thread which would clearly seem to violate the code in
AbstractBundle.beginStateChange which will quite clearly throw an error it
a separate thread has the bundle in a dirty state.
Perhaps there is no need for felix file install to actually force a package
refresh? Wouldn't that be automatically done by the framework itself on an
install/update/deletion?
Perhaps it's because it's trying to perform the process as a batch?
Here is the exact code in question:
// Handle deleted artifacts
// We do the operations in the following order:
// uninstall, update, install, refresh start.
Collection uninstalledBundles = uninstall(deleted);
Collection updatedBundles = update(modified);
Collection installedBundles = install(created);
Set toRefresh = new HashSet();
toRefresh.addAll( uninstalledBundles );
toRefresh.addAll(updatedBundles);
toRefresh.addAll( installedBundles );
findBundlesWithFragmentsToRefresh( toRefresh );
findBundlesWithOptionalPackagesToRefresh( toRefresh );
if (toRefresh.size() 0)
{
// Refresh if any bundle got uninstalled or updated.
*refresh((Bundle[]) toRefresh.toArray(new

}
The error results from the second last line above, but if we comment the
line as bdrawn mentions above, then it eliminates the error, but does it
leave the system in a state it shouldn't be in?

[equinox-dev] ?????? ?????? equinox bundle akin to felix fileinstall
I think the operation of refreshing for uninstalledBundles and updatedBundles
is required, but not for installBundles??And maybe there are some faults just
like what Raymond said.--
