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.
By default, toJSON won't convert objects with classes that aren't registered
explicitly. This caused errors when converting html_dependency objects.
Setting this option causes jsonlite to convert all objects, including
html_dependency objects.
- Unhandled observer error no longer stops flushReact in mid-flush
- Observer errors are now warnings that include the observer label
- Session is explicitly being closed by Shiny instead of by httpuv
Also:
- session$close() is now public and closes the session
This reverts commit 8d4b9076f7.
The main concern for the previous reversion was the Glimmer/Spark servers (Rcpp requires R >= 3.0.0). We are able to install Rcpp/httpuv under R 2.15.3 (https://gist.github.com/yihui/43a68d811dade1d9e828), so it is possible to upgrade Rcpp/httpuv/shiny on Glimmer/Spark. On the other hand, we are going to shut down Glimmer/Spark by the end of this year anyway, and move to ShinyApps.io, which makes this R 3.x issue even less of concern.
This reverts commit e4239c924b.
I totally forgot the problems this causes with R 2.15 and thus
glimmer/spark. httpuv 1.2.2 requires Rcpp 0.11 which requires
R 3.0. So existing installs (like glimmer/spark) that are
running just fine with httpuv 1.2.0 will be forced to upgrade,
which is hard to do when you don't know the provenance of
all the packages installed by your users.
- per @jcheng5's suggestion, RJSONIO::fromJSON(encoding = 'UTF-8') actually works (no longer need my markUTF8 function)
- removed the global option 'shiny.transcode.json'
also added a new method shinysession$registerDataObj(), which was designed to be a general data retrieval method: we can store arbitrary data objects as "downloads", and return arbitrary http response based on the filter function; see renderDataTable() and updateSelectizeInput() for two examples
