SaxonC 11.99 crashes with the following error:
muitithreading example with preview of SaxonC 12: Fatal error: StackOverflowError: Enabling the yellow zone of the stack did not make any stack space available
The failures happen under flask, but will try to reproduce it outside of flask. See example code below:
from flask import Flask
from flask import g
from saxonc import *
def get_saxon():
if 'saxon' not in g:
g.saxon = PySaxonProcessor(license = False)
return g.saxon
app = Flask(__name__)
@app.route('/')
def hello_world(): # put application's code here
return 'Hello World!'
@app.route('/saxontest2')
def saxontest2():
"""Returns result from Saxon XQuery evaluation"""
return get_saxon().new_xquery_processor().run_query_to_string(query_text = '"Hello from Saxon: " || current-dateTime()')
@app.teardown_appcontext
def teardown_saxonc_thread(exception):
saxon = g.pop('saxon', None)
if saxon is not None:
saxon.detach_current_thread
if __name__ == '__main__':
app.run()
Another example code which does not require flask:
import threading
import time
from saxonc import *
exitFlag = 0
class myThread(threading.Thread):
def __init__(self, threadID, name, counter, proc, xquery_processor):
threading.Thread.__init__(self)
self.threadID = threadID
self.name = name
self.counter = counter
self.xquery_processor = xquery_processor
self.proc = proc
def run(self):
print("Starting " + self.name)
example(self.name, self.counter, 5, self.proc, self.xquery_processor)
print("Exiting " + self.name)
def example(threadName, delay, counter, proc, xquery_processor):
while counter > 0:
if exitFlag:
threadName.exit()
time.sleep(delay)
result = xquery_processor.run_query_to_string(query_text='"Hello from SaxonC: " || current-dateTime()')
if result is None:
threadName.exit()
print("%s : %s" % (threadName, result))
counter -= 1
proc.detach_current_thread
def example2(threadName, delay, counter, xquery_processor):
while counter > 0:
if exitFlag:
return
time.sleep(delay)
result = xquery_processor.run_query_to_string(query_text='"Hello from SaxonC: " || current-dateTime()')
if result is None:
return
print("%s : %s" % (threadName, result))
counter -= 1
saxon_proc = PySaxonProcessor(license=False)
# Create new threads
thread1 = myThread(1, "Thread-1", 1, saxon_proc, saxon_proc.new_xquery_processor())
thread2 = myThread(2, "Thread-2", 2, saxon_proc, saxon_proc.new_xquery_processor())
# Start new Threads
thread1.start()
thread2.start()
thread1.join()
thread2.join()
print("Exiting Main Thread")

Some updates here, trying to run my Python Flask code using SaxonC (now the HE 12.0 release) continues to fail under WSL Ubuntu Linux on the very first attempt to use an SaxonC feature like XPath or XQuery or XSLT; here is an example stack on trying to evaluate XPath current-dateTime() with the REST API:

The full output is rather longish and I can't interpret much of it but for completeness I paste it below as well; what is more interesting, however, is that I also tried to upload the app to an azure Linux app service to see whether there on a server (probably in a docker container) it crashes that often and is kind of unusable as well but to my surprise it show a lot more stability there than on my attempts to run the app locally under WSL Linux. I don't know what is the difference so far, whether the "production WSGI server" they probably use on the azure app service is so much more stable than the development server Flask uses locally or what kind of settings do make the difference.

Fatal error: StackOverflowError: Enabling the yellow zone of the stack did not make any stack space available. Possible reasons for that: 1) A call from native code to Java code provided the wrong JNI environment or the wrong IsolateThread; 2) Frames of native code filled the stack, and now there is not even enough stack space left to throw a regular StackOverflowError; 3) An internal VM error occurred.

Fatal error: StackOverflowError: Enabling the yellow zone of the stack did not make any stack space available. Possible reasons for that: 1) A call from native code to Java code provided the wrong JNI environment or the wrong IsolateThread; 2) Frames of native code filled the stack, and now there is not even enough stack space left to throw a regular StackOverflowError; 3) An internal VM error occurred.

Some further investigation: as the app on azure runs Debian while I tried Ubuntu I have also tried to run WSL Linux Debian and Flask, but with the same result as long Flask uses its internal web server: the very first attempt to serve a HTTP request trying to use SaxonC HE doing XPath or XSLT or XQuery results in that crash.
Then I have investigated what a "production WSGI server" might be and how to use it and it turns out you can just do e.g. pip install gunicorn and then instead of running flask you run e.g. gunicorn -b 0.0.0.0:8000 app:app; and interestingly enough in the first few tests I have run now SaxonC doesn't crash the web server, it seems to run similar to the test app I installed on azure.
I still don't understand what makes the difference but that is at least a promising result, with a "production WSGI server" like that gunicorn you can run SaxonC HE Python with some responsiveness and stability and it looks as if without those dreaded "StackOverflowError: ... yellow zone .. crashes".

Hi, I have reproduced this crash using flask. Now investigating
Updated by Martin Honnen almost 2 years ago
I am currently running my code with Python 3.9 and Flask 2.2 on macOS 13 with a Mac Mini M1 and interestingly enough here the development server Werkzeug/2.2.2 Python/3.9.6 seems to run fine and stable, no crashes so far.
So my experience so far:
Under Windows with the Flask development server, you are able to run a couple of requests using SaxonC to do XPath and/or XSLT and/or XQuery, but at some point it crashes the server.
Under Linux (at least the WSL editions I use) any request trying to use SaxonC with the development server crashes directly but if you switch to a "production server" like gunicorn all runs fine and stable. I have also for a test deployed to app to an Azure server with Linux and gunicorn and there it also runs stable.
On MacOS it looks as even the development server runs fine and stable.
Perhaps that helps anyone else trying to use SaxonC with Python in a Flask web app.

- Status changed from New to In Progress
I have finally managed to solve this bug issue. A call to the attachCurrentThread() method is required in the SaxonProcessor C++ constructor.

I have been using FastAPI webserver for testing which is working as expected.

I'm impacted by this bug while working on SaxonC HE from python under Linux. Great news that you managed to solve the bug. How can be benefit from the fix? Should we wait for a new release (12.1) ?
