Could you upgrade the documentation (Doc/library/profile.rst) and add a ..versionadded:: 3.8 ?

Thanks! addressed

Updated, let me know how it looks for you @matrixise. If the wording and structure looks ok we can see if any core developer is interested in this. It is a "nice to have change" as it is mainly useful for people not having cProfile available but not really urgent. |
|
Thanks for your review @matrixise ;) |
|
no problem, but I am not a core dev, you have to wait and see with a core review, maybe there will an other point to fix, but in this case, it's good adventure ;-) thanks again ;-) |

As a note for the reviewer, this follows the same implementation as the one in This, therefore, includes by default the functions of using The change (if desired) to move to use the source directly can be done either in this PR or in a different one, but that will require either hitting the private API in runpy, see #5474 as an example. |

@ncoghlan we stalled this PR based on one where we were going to refactor part of the logic to extract the module details in runpy, but we agreed here that it probably makes no sense to do so. Do you want to proceed with this PR as is? Let me know if you think it is not worth or any change should be done. I am happy to close it otherwise if you want. (really, no hard feelings I promise I am also happy to have a look to the issue that this implementation brings as commented in [here]#5132 (comment)) in a latter PR. And "fix" both cProfile and profile if desired. But I'd prefer to leave that conversation for a different issue + PR. Same goes about #5134 |
|
@mariocj89 Yeah, let's go ahead with updating the existing PRs and at least offering the functionality, even if it interacts a bit differently with the interpreter level "-i" switch when compared to the directly executing a path. |
The new option in the CLI of the profile module allow to profile executable modules. This change follows the same implementation as the one already present in `cProfile`.
As the argument is now present on both modules, move the tests to the common test case to be run with profile as well.

@ncoghlan, updated per previous comment, let me know of any change that needs to be done here :) Thanks! I've also updated #5134 |

@ncoghlan: Please replace |
Port of #4297 to the pure python profile module.
The patch adds a new option -m that allows the profile CLI to run modules as scripts.
