It is dangerous to set this on a per-process basis. If we even
still want the ability to have observer errors not kill the
session (debatable) we should do so by having an option on the
session object that is set when the shiny server function runs.
Not only does this remove support for the option, but now we
will refuse to connect and will abort the session if the option
is set to a non-NULL value. This is to prevent apps from moving
forward with the assumption that their option will work, when
it really won't. (I doubt anyone is using it anyway, it's so
obscure...)
- More selective removal of frames at end of call stack
- Add withLogErrors, printError, stripStackTrace convenience funcs
- Properly capture/log errors for various levels of unhandled errors
- Unhide stacks for flush/flushed/sessionended callbacks
The session$makeScope function was not correctly taking the session's
own namespace into account (i.e. all makeScope() method calls were
being performed against the root session).
Instead of showing the code, try to just show the name
of the reactive/output. Uses a fairly flaky algorithm
for determining the name of the reactive; will only
work in cases where the definition of the reactive
begins with "foo <- reactive({".
- Need to carefully review ShinySession, think about
each and every public method and whether it should
be passthrough or do something different for a
namespaced session.
- It would be nice if we do the namespace splitting
at the server.R level and actually have numerous
reactivevalues objects for inputs, one for each
namespace. This will make the reactive hooks for
names() and reactiveValuesToList() correct, as
right now they will oversubscribe if you're in a
namespaced session. Also it would prevent outer
sessions from seeing the values of their child
namespaces. (Though is that good or bad...?)
This reverts commits deffc90, ab4dc64, and 0755579, returning to RJSONIO.
The purpose of this is to prepare for a maintenance release for 0.11
without the switch to jsonlite, to reduce the risk of new bugs.
