Copy of the C comment:
Perform basic peephole optimizations to components of a code object.
The consts object should still be in list form to allow new constants

To keep the optimizer simple, it bails out (does nothing) for code that
has a length over 32,700, and does not calculate extended arguments.
That allows us to avoid overflow and sign issues. Likewise, it bails when
the lineno table has complex encoding for gaps >= 255. EXTENDED_ARG can
appear before MAKE_FUNCTION; in this case both opcodes are skipped.
EXTENDED_ARG preceding any other opcode causes the optimizer to bail.
Optimizations are restricted to simple transformations occuring within a
single basic block. All transformations keep the code size the same or
smaller. For those that reduce size, the gaps are initially filled with
NOPs. Later those NOPs are removed and the jump addresses retargeted in
a single pass. Code offset is adjusted accordingly.

another one (ie `next_block` is set)
- the required stack from the stack if we went through all the instructions

In the first case, the calling function is then responsible for creating a

determine the stacksize required by the block and resuming this function

It's possible to overcome this limitation by using `ForkSafeLock.acquire` and

remove the key when it's garbage-collected), so, we can get into a recursion.

This may mean a number of things:
- This evaluation is really slow and this is expected.
In this case it's possible to silence this error by raising the timeout, setting the
PYDEVD_WARN_EVALUATION_TIMEOUT environment variable to a bigger value.
- The evaluation may need other threads running while it's running:
In this case, it's possible to set the PYDEVD_UNBLOCK_THREADS_TIMEOUT
environment variable so that if after a given timeout an evaluation doesn't finish,
other threads are unblocked or you can manually resume all threads.
Alternatively, it's also possible to skip breaking on a particular thread by setting a
`pydev_do_not_trace = True` attribute in the related threading.Thread instance
(if some thread should always be running and no breakpoints are expected to be hit in it).
- The evaluation is deadlocked:
In this case you may set the PYDEVD_THREAD_DUMP_ON_WARN_EVALUATION_TIMEOUT
environment variable to true so that a thread dump is shown along with this message and
optionally, set the PYDEVD_INTERRUPT_THREAD_TIMEOUT to some value so that the debugger
tries to interrupt the evaluation (if possible) when this happens.

Based on the python xreload.
Changes
======================
1. we don't recreate the old namespace from new classes. Rather, we keep the existing namespace,
load a new version of it and update only some of the things we can inplace. That way, we don't break
things such as singletons or end up with a second representation of the same class in memory.
2. If we find it to be a __metaclass__, we try to update it as a regular class.
3. We don't remove old attributes (and leave them lying around even if they're no longer used).
4. Reload hooks were changed
These changes make it more stable, especially in the common case (where in a debug session only the
contents of a function are changed), besides providing flexibility for users that want to extend
on it.
Hooks
======================
Classes/modules can be specially crafted to work with the reload (so that it can, for instance,
update some constant which was changed).
1. To participate in the change of some attribute:
In a module:
__xreload_old_new__(namespace, name, old, new)
in a class:
@classmethod
__xreload_old_new__(cls, name, old, new)
A class or module may include a method called '__xreload_old_new__' which is called when we're
unable to reload a given attribute.
2. To do something after the whole reload is finished:
In a module:
__xreload_after_reload_update__(namespace):
In a class:
@classmethod
__xreload_after_reload_update__(cls):
A class or module may include a method called '__xreload_after_reload_update__' which is called
after the reload finishes.
Important: when providing a hook, always use the namespace or cls provided and not anything in the global
namespace, as the global namespace are only temporarily created during the reload and may not reflect the
actual application state (while the cls and namespace passed are).
Current limitations
======================
- Attributes/constants are added, but not changed (so singletons and the application state is not
broken -- use provided hooks to workaround it).
- Code using metaclasses may not always work.
- Functions and methods using decorators (other than classmethod and staticmethod) are not handled
correctly.
- Renamings are not handled correctly.
- Dependent modules are not reloaded.
- New __slots__ can't be added to existing classes.
Info
======================
Original: http://svn.python.org/projects/sandbox/trunk/xreload/xreload.py
Note: it seems https://github.com/plone/plone.reload/blob/master/plone/reload/xreload.py enhances it (to check later)
Interesting alternative: https://code.google.com/p/reimport/
Alternative to reload().
This works by executing the module in a scratch namespace, and then patching classes, methods and
functions in place. This avoids the need to patch instances. New objects are copied into the
target namespace.

This may mean a number of things:
- This evaluation is really slow and this is expected.
In this case it's possible to silence this error by raising the timeout, setting the
PYDEVD_WARN_EVALUATION_TIMEOUT environment variable to a bigger value.
- The evaluation may need other threads running while it's running:
In this case, you may need to manually let other paused threads continue.
Alternatively, it's also possible to skip breaking on a particular thread by setting a
`pydev_do_not_trace = True` attribute in the related threading.Thread instance
(if some thread should always be running and no breakpoints are expected to be hit in it).
- The evaluation is deadlocked:
In this case you may set the PYDEVD_THREAD_DUMP_ON_WARN_EVALUATION_TIMEOUT
environment variable to true so that a thread dump is shown along with this message and
optionally, set the PYDEVD_INTERRUPT_THREAD_TIMEOUT to some value so that the debugger
tries to interrupt the evaluation (if possible) when this happens.

omniverse-code/kit/exts/omni.kit.debug.python/debugpy/_vendored/pydevd/_pydevd_bundle/pydevd_comm.py | ''' pydevd - a debugging daemon
This is the daemon you launch for python remote debugging.
Protocol:
each command has a format:
id\tsequence-num\ttext
id: protocol command number
sequence-num: each request has a sequence number. Sequence numbers
originating at the debugger are odd, sequence numbers originating
at the daemon are even. Every response uses the same sequence number
as the request.
payload: it is protocol dependent. When response is a complex structure, it
is returned as XML. Each attribute value is urlencoded, and then the whole
payload is urlencoded again to prevent stray characters corrupting protocol/xml encodings
Commands:

r"""Utilities to compile possibly incomplete Python source code.
This module provides two interfaces, broadly similar to the builtin
function compile(), which take program text, a filename and a 'mode'
and:
- Return code object if the command is complete and valid
- Return None if the command is incomplete
- Raise SyntaxError, ValueError or OverflowError if the command is a
syntax error (OverflowError and ValueError can be produced by
malformed literals).
Approach:
First, check if the source consists entirely of blank lines and
comments; if so, replace it with 'pass', because the built-in
parser doesn't always do the right thing for these.
Compile three times: as is, with \n, and with \n\n appended. If it
compiles as is, it's complete. If it compiles with one \n appended,
we expect more. If it doesn't compile either way, we compare the
error we get when compiling with \n or \n\n appended. If the errors
are the same, the code is broken. But if the errors are different, we
expect more. Not intuitive; not even guaranteed to hold in future
releases; but this matches the compiler's behavior from Python 1.4
through 2.2, at least.
Caveat:
It is possible (but not likely) that the parser stops parsing with a
successful outcome before reaching the end of the source; in this
case, trailing symbols may be ignored instead of causing an error.
For example, a backslash followed by two newlines may be followed by
arbitrary garbage. This will be fixed once the API for the parser is
better.
The two interfaces are:
compile_command(source, filename, symbol):
Compiles a single command in the manner described above.
CommandCompiler():
Instances of this class have __call__ methods identical in
signature to compile_command; the difference is that if the
instance compiles program text containing a __future__ statement,
the instance 'remembers' and compiles all subsequent program texts
with the statement in force.
The module also provides another class:
Compile():
Instances of this class act like the built-in function compile,
but with 'memory' in the sense described above.
