What Hacker News says
7 sourcesThe number of patches is going down with time and many are trivial one liners, e.g. uvloop
https://github.com/oracle/graalpython/blob/b907353de1b72a14e...
- self.cython_always = False
+ self.cython_always = True
That's the entire patch. Others are working around bugs in the C extensions themselves that a different implementation happens to expose, and can be upstreamed:
https://github.com/oracle/graalpython/blob/b907353de1b72a14e...
Still others exist for old module versions, but are now obsolete:
https://github.com/oracle/graalpython/blob/b907353de1b72a14e...
# None of the patches are needed since 43.0, the pyo3 patches have been upstreamed
And finally, some are just general portability improvements. Fork doesn't exist on Windows. Often it can be replaced with just starting a sub-process.
So the patching situa

tion has been getting much better over time, partly due to the GraalPy team actively getting involved with and improving the Python ecosystem as a whole.
I think GraalPython does have a GIL, see https://github.com/oracle/graalpython/blob/master/docs/contr... - and if by "there is no such thing on those platforms" you mean JVM/CLR not having a GIL, C also does not have a GIL but CPython does.
In GraalPy – A high-performance embeddable Python 3 runtime for JavaI'm wondering whats the state of GraalPy - seems it support many of pip extensions.

In FastHTML – Modern web applications in pure PythonThose are bridges to native CPython.
There is also GraalPy (https://github.com/oracle/graalpython),
which is a standalone implementation more similar to Jython.
It seems already quite compatible with Python 3.
I have tested the latest version graalpy-community-23.1.2 as a regular Python interpreter from the command line (i.e., not through a Java program).
It was able to run my standard library-only Python scripts,
as well as a script that made async HTTP requests with the external library HTTPX.
It couldn't run a TUI program that used the Python Prompt Toolkit (`AttributeError: module 'signal' has no attribute 'siginterrupt'`).
I am curious about your experience if you have used GraalPy more than I have.
