Service Protocol:
- _clearVMTimeline (clear timeline)
- _getVMTimeline (fetch timeline)
- _setVMTimelineFlag (control recording)
- _getVMTimelineFlag (...)
- _getVMTimeline service unit test
Observatory:
- timeline page with record on/off, clear timeline, and refresh buttons.
- trace-viewer based timeline view that runs in an iframe driven by a small javascript program
Misc:
- Fix default enable logic bugs
- Add 'Debugger Pause' timeline event
- Threads can have a name and that name will be displayed in Observatory
- Tighten up locking when printing JSON

- Views for ObjectPool, Instructions, ICData.
- Allow querying retained size of non-Instances.
- References to non-Dart functions as links.
- Find ic data array from a Function.
- Fix NPE when current token position in a script inset cannot be mapped.

In JSON RPC, error results and regular results are distinguished structurally. We now do this in the service protocol instead of returning a regular result with the "Error" type.
VM:
- Add PrintError method to JSONStream. Use this to generate all errors in the service protocol.
- Fix some bugs with "limit" parameter handling.
- Change return value for heap rpcs when they find a collected/expired reference.
- Update tests.
Observatory:
- Add app.handleExceptions -- this is a widely-used exception handler that puts up a notification when there is an uncaught/unexpected exception. Added a top-level zone catch that uses this handler, as well as explicit uses of this handler at various points in the code. Most pages use this implicitly or explictly, except for the debugger page, which displays exceptions in the console.
[ General rule, when a function returns a Future, generally let the error pass through. If a function does async work but doesn't return the Future, then it should handle errors explicitly by calling app.handleExceptions, etc. ]
- Fixed notifications. They were generally broken. Some hard-coded type names needed to be fixed, some hacks needed to be removed.
- Add a new class RpcException and a variety of subclasses which capture the error cases when making an rpc.
- Redo refresh buttons so their callbacks return Futures instead of taking a "done" closure. Cleaner. Allows us to move error handling outside of the callback.
- Drop ServiceError, ServiceException and the associated views.
- Redo notifications so that event and exception notifications are supported.
- No longer null out the vm when it is disconnected.
- Remove notifications when we visit the vm-connect page. Only show the "Proceeding will lose current page" dialog when we aren't on the vm-connect page already.
- Improve error message on cpu profile page when profiling is disabled on the VM.
- Allow variables to wrap on debugger page.
- Make eval-box and eval-link tolerant of errors during rpc. Make the errors display nicely.
- When a breakpoint is marked "not possible", make sure it disappears. This got broken during script view refactor.
- Drop vm's errors and exceptions streams. No longer needed.

Service
- Remove support for old-style service requests.
- Drop 'arguments' from JsonStream and ServiceRequestHandler.
- Json-rpc inspired renaming: command->method, options->params all over.
- Implement getFlagList, setFlag, getObjectByAddress.
- Add helpers PrintMissingParamError and PrintInvalidParamError
to make our error messages more regular.
- Update tests.
- Service_SetSource removed for now. John will resurrect.
Observatory
- Drop all Deprecated 'get' functions. We now use json rpc for everything.
- Drop 'link' and 'relativeLink' from ServiceObject -- they were
ui-specific and they are no longer meaningful anyways. Use 'id' instead.
- New pages: VMPage, FlagsPage, InspectPage, ErrorPage. All urls
used by Observatory are now 'new school' and have a proper
prefix. ErrorPage is the new catch-all.
- Pages now use a Uri instead of a url String. This lets them
grab query parameters more easily.
- SimplePage replaces IsolateSuffixPage.
- We now use gotoLink() or makeLink() to make our navigation
links. gotoLink gets some optional parameters to make it
easier to construct links to ServiceObjects.
- Rework mouse clicks on the heap map to use getObjectByAddress.
- Remove the breakpoint_list. It wasn't working. I'll add it back later.
- Silence logging of getIsolateMetric/getVMMetric.

2) Move observatory from runtime/bin/vmservice/observatory to runtime/observatory
3) Add two tools scripts:
- tools/run_pub.py (runs pub before SDK is built)
- tools/obs_tool.py (helper for get, build, and deploy stages)
4) Build Observatory with runtime:
- pub get --offline
- pub build
- deploy
5) Build artifacts are now in standard output directory, for example, out/DebugIA32/observatory.
6) Add a new 'dart_boostrap' host target (no snapshot, no observatory) that can be used as the Dart executable to run pub when building Observatory. This is behind a build.py flag --use-bootstrap-for-observatory because:
- It is only necessary on older Linux distributions that are incompatible with the prebuilt Dart testing executable.
- running pub build with the boostrap Debug build is significantly slower.
7) Detect if the prebuilt executable doesn't work and automatically switch to the 'dart_bootstrap' executable. Also, warn the user and provide a Wiki link with more information.
