By default, profilers are disabled. To enable profiling, set the environment variable `PYQTGRAPHPROFILE` to a comma-separated list of fully-qualified names of profiled functions. Calling a profiler registers a message (defaulting to an increasing counter) that contains the time elapsed since the last call. When the profiler is about to be garbage-collected, the messages are passed to the outer profiler if one is running, or printed to stdout otherwise. If `delayed` is set to False, messages are immediately printed instead. Example: def function(...): profiler = Profiler() ... do stuff ... profiler('did stuff') ... do other stuff ... profiler('did other stuff') # profiler is garbage-collected and flushed at function end If this function is a method of class C, setting `PYQTGRAPHPROFILE` to "C.function" (without the module name) will enable this profiler. For regular functions, use the qualified name of the function, stripping only the initial "pyqtgraph." prefix from the module.

This class is very useful for tracking memory leaks. The class goes to great (but not heroic) lengths to avoid tracking its own internal objects. Example: ot = ObjTracker() # takes snapshot of currently existing objects ... do stuff ... ot.diff() # prints lists of objects created and deleted since ot was initialized ... do stuff ... ot.diff() # prints lists of objects created and deleted since last call to ot.diff() # also prints list of items that were created since initialization AND have not been deleted yet # (if done correctly, this list can tell you about objects that were leaked) arrays = ot.findPersistent('ndarray') ## returns all objects matching 'ndarray' (string match, not instance checking) ## that were considered persistent when the last diff() was run describeObj(arrays[0]) ## See if we can determine who has references to this array Nci|_i|_i|_i|_i|_dt j t|<|j|j|j|j|j|jg|_ |jj|j|jD]}dt j t|< |jyr;) startRefs startCountrpersistentRefsobjTypesrQallObjsrrrr3r?r+vs rr,zObjTracker.__init__s   '+ 2d8$]]DNNDOOT\\SWSfSfhlhuhuv  # -A(,J  r!u % - r$c:|j|j|S)zZReturn all objects matching regex that were considered 'new' when the last diff() was run.) findTypesrr+rs rfindNewzObjTracker.findNews~~dllE22r$c:|j|j|S)zaReturn all objects matching regex that were considered 'persistent' when the last diff() was run.)r[rUr\s rfindPersistentzObjTracker.findPersistents~~d11599r$c|j\}}}|jD] }|j|j|"|jj|jj ||D]}|j ||j j|j j |y)z Remember the current set of objects as the comparison for all future calls to diff() Called automatically on init, but can be called manually as well.
