evanhempel / python-flamegraph Goto Github PK

=_=

python-flamegraph should be available on PyPi, pip install python-flamegraph works.

i cannot start it because No module named flamegraph.

but i have installed: pip install git+https://github.com/evanhempel/python-flamegraph.git

what can i do here?

I have a simple python web program which uses jinja2 and Quart, when I run python server_async.py, everything is fine. But when I run python -m flamegraph -o perf.log server_async.py, it reports errors:

...
File "server_async.py", line 254, in index
template = await render_template('index.html')
...
jinja2.exceptions.TemplateNotFound: index.html

I guess this is because flamegraph does not work with Quart and jinja2, right?

Would you mind terribly uploading python-flamegraph to PyPI? It's a simple process:

• sign up for an account
• run python setup.py sdist register upload
• enter the username and password when asked

(People will tell you to run twine upload instead, because distutils do not verify SSL certificates, but I think that means you need to register the project manually via some web form, instead of having setup.py register take care of everything.)

The sdist package at PyPI is missing LICENSE file.

I'm getting an error running this. Seems to work fine on Python 3.7, but on 3.8, I get the following.

Traceback (most recent call last):

At least for time.clock(), it seems like there are alternatives in 3.8.

Hi there!

Thanks for sharing this, I'm really looking forward to putting your tool to good work :-)

I got here looking for a way to profile pip install because it's much slower on some machines than others. I was hoping to profile it using flamegraph pip install ..., but I take it that flamegraph expects its first argument to be a file.

The coverage tool supports this (ref for inspiration). Would you be willing to accept a contribution that adds something similar?

Now only the functions in the script that is profiled are added to the log. It would be really great to also know what takes time in functions from other modules imported by the profiled script.

I would like to be able to pip install the latest version from PyPI with your awesome changes. :)

i.e. how to get a log for an individual request?

https://github.com/evanhempel/python-flamegraph/blob/master/flamegraph/flamegraph.py#L90 has a string that's split over multiple lines, but this is a syntax error for me. Easy fix is probably to just add some singlequotes to use the python parser's implicit string concatenation.
