asyncio-context 0.0.1

Description:

asynciocontext 0.0.1

asyncio-context
Tool for store data within asyncio task (for example, in all coroutines across handling aiohttp request) and enrich logging record with this data.
Small, nice-looking and with annotations.
Install
pip install asyncio-context
Example
It can be used for logging trace id and other info about request:
...
'formatters': {
'standard': {
'format': '[trace_id:%(trace_id)s] [user_id:%(user_id)s]:%(message)s'
},
},
'filters': {
'context2record': {
'()': 'asyncio_context.logging.Context2Record',
'ctx_name': 'ViewsCtx'
},
},
...

from asyncio_context import Context

class ViewsCtx(Context):
user_id: str = 'UNKNOWN'
trace_id: str = 'NO_TRACE'

ctx = ViewsCtx()
log = logging.getLogger()

class MyView(web.View):
async def get(self):

ctx.trace_id = self.request.headers.get('X-Trace-Id', str(uuid.uuid4()))
# or
ViewsCtx().user_id = self.request.match_info.get('user_id')

log.info('Test request')
# GET http://localhost:8080/user/123
# [trace_id:ea38e89d-fba1-40a3-899e-297c6cd76732] [user_id:123]:Test request

Context can be copied to another asyncio task:
task = asyncio.get_running_loop().create_task(another_task())
ViewsCtx.copy_to_task(task)
