abcb24f4de [Dynamo][Better Engineering] Add typing annotations to guard and source (#158397) 
As part of better engineering week, we would like to improve out type support to improve dev experience in dynamo

This PR adds strict typing support to a critical set of files for dynamo, `source.py` and the base `_guards.py`

Running
```
mypy torch/_dynamo/source.py torch/_guards.py --linecount-report /tmp/coverage_log
```

b1a0c34dd3 [pt2 event logging] add configurable prefix (#157678) 
Summary:
# Why

make experiments easier to find

# What

- dynamo config to provide a prefix
- use the prefix when sending data to scuba through the self.id_ field

Test Plan:
```
# code edited to set the prefix as `coconutruben-02`
buck2 run mode/opt scripts/coconutruben/torchmm:experiment 2>&1 | tee /tmp/epx040
```

22920c9138 Grab bag of (mostly) typing improvements (#158075) 
Collects some scattershot improvements made while attempting to enable training for AOTInductor. Non-typing changes are:

1. Swapping a few custom searches for the output node in an FX graph for calling `graph.output_node()`.
2. Removing two unused parameters from `torch.export._unlift._unlift`.
3. Switching handles to constants in `cpp_wrapper_cpu` to use C++ references for memory efficiency.
4. Cleaning out unused, unexported imports from `torch/export/__init__.py`, and adding one missing export to `__all__`.

94995eba07 [Log] add a hook for recompile user context (#157961) 
Users may want compile-related but customized logging info to dynamo_compile. One example is to logging the current training iteration index when recompilation happens. In general, current training iteration index is not available to compiler, since the same compiled function may be called multiple times in the same training iteration. The user could provide the training iteration index in a user hook where torch.compile logs it when recompilation happens.

b2fc9cfea1 [precompile] Add CompilePackage to serialize dynamo states. (#155118) 
Adding a per torch.compile() object CompilePackage which tracks dynamo artifact. CompilePackage is considered a low level component and should not be directly exposed to end users. It has the following interface:

1. `CompilePackage.__init__()` which optionally takes previously serialized dynamo states.
     a. when `dynamo` argument is None, it will contruct a brand new CompilePackage object.
     b. when `dynamo` argument is not None, it will load a pre-compiled dynamo state.
2. `package.save()` which dumps the dynamo states into _DynamoCacheEntry.
3. `package.install(backends)` which will handle all the side-effectful global scope updates with compiled functions and resume functions.

This diff focus on making the low level mechanism for precompile. It will be left to upper level interface to use these API to build more user-facing frontend.

c4b93e6579 Replace frame_traced_fn hook with get_traced_code() util (#155249) 
#153622 introduced a hook for getting the relevant code objects after frame tracing. The idea is to have vLLM use this instead of monkey-patching `inline_call_()` to determine the source code files to hash. Unfortunately, the hook runs too late; the vLLM backend needs access to the set of source code filenames while it's running.

This PR replaces the newly-added hook with a utility function that a backend can call to get this information. I've made the change in vLLM and can verify that this allows the information to be queried at the right time.

```
import torch
from torch._dynamo.utils import CHROMIUM_EVENT_LOG
class Foo:
  pass
torch._dynamo.utils.CHROMIUM_EVENT_LOG =  Foo()

print(CHROMIUM_EVENT_LOG) # None
```

Change logging.error to logging.exception to log additional information when relevant.  A few places have slipped in logging.errors in try except since I last did a clean up here and the rule is stabilized so I am enabling it codebase wide. I have NOQA'd much of our custom exception stack trace handling for RPC calls and distributed and tried to a fix a few errors based on whether we immediately reraised it or if we didn't print any exception handling where it could be useful.
