guppy3's Issues

python.exe crashed on hpy.heap() after Import Official Dropbox SDK for Python

Hi @zhuyifei1999,

Happened in Windows OS.

Installed Official Dropbox SDK from https://pypi.org/project/dropbox/.
pip install dropbox

Ran Python Interpreter
python

Python 3.8.10 (default, May 19 2021, 13:12:57) [MSC v.1916 64 bit (AMD64)] :: Anaconda, Inc. on win32

import dropbox

If skip importing Dropbox SDK or hpy().heap(), there is no issue.

It is a showstopper issue to me as I'm looking forward for both dropbox and guppy module to work together.

Idea: Save the entire reference graph (to make profile browsers more useful)

Right now it just saves all the rows in the stats. That's someone one could use .all and just save the string.

Deal with upcoming per-interpreter GIL

Per-interpreter GIL might be coming to Python 3.9 [1]. We have zero thread-safety and rely on GIL to make sure other threads don't modify stuffs when we are accessing them. With per-interpreter GIL, traversing across interpreter boundary is unsafe... ideas?

The reference chains seem to contain unexpected values.

If the tracer / profiler is completely C then it works fine (try using profile and cProfile to profile the tests).

@svenil found that this is probably related to the use of PyFrame_FastToLocalsWithError in call_trampoline, and test.test_sys.SysModuleTest.test_refcount & test.support.refcount_test may explain the reason.

Idea: by 'producer' / by 'line of allocation' classifier?

Quote the thesis:

A producer profile classifies cells by the program components that created them.

Of these, the producer profile would require special instrumentation of the Python interpreter to record the call stack when allocating objects, and is therefore outside the current scope of Heapy.

But we no longer need special instrumentation now that Python 3 supports it natively:

  File "/usr/lib/python3.7/tracemalloc.py", line 235
    def get_object_traceback(obj):

We could probably somehow use tracemalloc instead of hook into python memory allocator to avoid reinventing the wheel. However, this has a non-negligible memory overhead so we probably don't want to enable it as default and show a message if no object would be classified this way.

Similarly, it would be nice if we could get the trace of a single object with some convenient attribute access on an identityset. Though, admittedly, reference graphs are far more useful.

How should this classifier be called? byprod? bytrace? byalloc?

rlcompleter on a heap is super expensive

Not sure if this is fixable on our side, but I should document this:

$ python -i -c 'hp = __import__("guppy").hpy()'
>>> h = hp.heap()
>>> h.[TAB][TAB][HANGS]

Usage with JAX

I would like to dive deeper into the memory consumption of a program using JAX's numpy. However, with guppy I am unfortunately not able to get out any information since the formatting of the result fails during stringifying and printing the result. One can easily reproduce the error using the following simple program:

from jax import numpy as jnp

from guppy import hpy

a = jnp.linspace(0.0, 1.0)

h = hpy()  # succeeds
print(h.heap())

I know it might be quite a stretch to ask guppy to support custom libraries like JAX so I would already be happy about insights into how to resolve it myself or at least how to work-around it.

Remote monitor mode not available for python >3.8 ?

Hi, I'm using python 3.10 in one of my projects and wanted to use the remote monitoring mode from guppy3. However, after adding
import guppy.heapy.RM I get an error saying AttributeError: module 'guppy.heapy.heapyc' has no attribute 'interpreter'.

After some digging, I found that the interpreter is not available for python version above 3.8 (found here)

Is there any specific reason for this ? In the Readme, it's specified that the package works with python 3.9, 3.10 and 3.11.

Any help here would be appreciated :)

Question: How to analyze guppy heap files

Thank you for porting guppy to the latest and greatest Py3. I am wondering how to analyze guppy heap files that has been dump to files with some UI/console tools?

Add support to release aarch64 wheels

Problem

On aarch64, pip install guppy3 builds the wheels from source code and then install it. It requires user to have development environment installed on his system. also, it take some time to build the wheels than downloading and extracting the wheels from pypi.

Resolution

On aarch64, pip install guppy3 should download the wheels from pypi

@zhuyifei1999 , Please let me know your interest on releasing aarch64 wheels. I can help in this.

[Question] How does `theone` return the Python object?

I am trying to understand the inner workings of guppy. I am curious how the following method in IdentitySetSingleton actually works to return the actual Python object:

    def _get_theone(self):
        return self._node

Looking through the C extension code in hv.c, I see in hv_heap() function that it calls hv_heap_rec() which in turn calls NyNodeSet_setobj(). In NyNodeSet_setobj(), Py_INCREF() is called to increase the reference count of each obj. But in the code, I don't see where obj is stored in a node?

Thank you for your explanation.

str() doesn't work on .more though repr() does (in the .byid case at least)

Example:

>>> from guppy import hpy
>>> h=hpy()
>>> x=h.idset(range(100)).byid
>>> print(repr(x.more))

Stack overflow on long linked list during traversal

This bug was first reported at:
https://sourceforge.net/p/guppy-pe/bugs/20/

Can we do something about it? It is probably a stack overflow. It would be better if we could check for stack size and report an exception instead of trigging a segmentation fault.

PathsIter missing next method

When doing the following we get an exception. It seems Python3 needs the next method for iterator not the "_ next _" method. When I define the next method in PathsIter in guppy/heapy/Path.py it works. I have tested in the Guppy3-3.0.3 release as well as latest trunk as of today 10 sep 2019.

Feature: monitor external python process, possibly by injecting a stub?

Hello @zhuyifei1999,

I wanted to learn if I can use guppy to monitor an external process? My use case is that a python process is already running. I want to monitor the heap size over hours/days. It is a daemon, a long-running process, and based on how to use the guppy3, it seems I need to be inside that process to query the heap, this is not desirable for my use case.

Could you help to share your thoughts with me?
Thank you

Is it possible to dump the memory snapshot for offline analysis?

Hi,

I got this question after checking out #24 .

In fact, I have some memory issues with my Django server, but the online environment is not quite reachable for some reason.

Therefore, I wonder whether guppy3 provides any approaches to dump the memory/heap snapshot so that I can retrieve the snapshot via an API and do the rest of the analysis offline.

Thanks.

Performance hit when classifying many dicts (non-GC-tracked and with no owner)

This occured in commit 6373998 which was apparently after V3.0.6 was released.

In hv_cli_dictof_update_new_method in src/hv_cli_dictof.c, the call to hv_get_objects was replaced with a call to gc_get_objects. This was to be faster because of an easier way to find objects and they were also fewer. However, we didn't get non-gc-collected objects such as simple dicts with non-gc-collected members. This made the hv_cli_dictof_update method be called each time we tried to classify such dicts, from hv_cli_dictof_classify, because we didn't store any information about those dicts in the nodegraph self->owners. The classifier thought it needed more information each time.

Code classifying an idset() of a list of 5000 empty dicts went from about 0.3 seconds (with the change reverted) to 9 seconds in Python 3 with the modification mentioned.

# dictofno.py
from guppy import hpy
h=hpy()
d=[{} for i in range(5000)]
print (h.idset(d))

Checking in the debugger revealed that the update function was called many times.

It has been suggested (by the author of Guppy 3, YiFei Zhu) that the hv_cli_dictof_classify function should call the update method only once.

I presume this means only once during the lifetime of the classifier. I think this would work if the classifier is allocated together with the set it classifies, because those sets are immutable so the classification would not change. I think this is the current situation.

However, if we would turn to have memoized classifiers in the Heapy guppy.hpy() structure, (to speed things up) then there might be the case that new dicts are created that should require to update the dict ownership graph.

Then it would require many calls to update during the lifetime of the classifier. I don't know if this will be a reality but it may be something to consider.

guppy.heapy.test.test_gsl: FileNotFoundError (docexample.gsl)

Hi,

I pulled the last checkin after v3.0.6 from Master, installed it and tested it. Unfortunately, it seems to be something wrong with how the test skips the test in main() of SpecNodes.py.

There is a check for file not found in SpecNodes.py:

        if not root.os.path.exists(main_dt_name):
            print('%s does not exist, skipping test' % main_dt_name)

However, it seems to be missing a return statement there. I get:

FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/lib/python3.6/dist-packages/guppy3-3.0.6-py3.6-linux-i686.egg/guppy/gsl/../../specs/docexample.gsl'

I put a return after the print above and then the test was skipped and it could continue with the other tests.

As a side note, would it be a bad idea to install the specs/*.gsl files?
I see that I am also not installing those files in Guppy-PE/0.1.11.
But maybe we could consider installing them?

Regards
Sverker

AttributeError with guppy.heapy.UniSet.IdentitySetMulti.partition

When trying to print heap, I got an AttributeError. I tweaked the code a bit in UniSet.py to report the types of self and a as well as b:

raise AttributeError(f"{type(self)}.{type(a)}.{b}")
AttributeError: <class 'guppy.heapy.UniSet.IdentitySetFamily'>.<class 'guppy.heapy.UniSet.IdentitySetMulti'>.partition

Is this expected?

Thanks.

Getting text output from tool

Hi! Thanks for this tool. I'm trying to figure out why some Django Gunicorn processes are so large.

I'd like to either log the heap or even possibly make the heap into a view in Django so I can see the heap -- but I can't figure out how to get a textual representation of the output instead of the interactive one.

Is this possible?

The offending module is a tuple:

which has no dict attribute.

Would you accept a PR to look for the dict attribute in View.py and skip anything that doesn't have that attribute?

Thanks

Feature: replace/patch an imported class at runtime

Suppose we have the following file structure：

files/
    a.py
    b.py
main.py

And each file contains codes like:

# a.py
class A():
    pass

# b.py
from .a import A
class B():
    self.some_attrs = A()

# main.py
from files import B

obj = B()

Is this possible to replace the imported class A with another class using guppy3? And then when execute obj = B(), the new class will be constructed and attached to self.some_attrs

Provide `guppy.version`

Dubious assignment to be a check in hv_cli_and.c

This assignment that will be a check is dubious. It is the same for the two cases. Suggest to fix and also have a test case that catches it, if possible. Does the code in nodetuple_richcompare work as intended? I don't understand it after these years.

hv_cli_and.c, lines 235-236

       vi = (Py_ssize_t)vt->ob_item[i];
       **wi = (Py_ssize_t)vt->ob_item[i];**
