The reset_peak function sets the peak memory size to the current size,
representing a resetting of that metric. This allows for recording the
peak of specific sections of code, ignoring other code that may have
had a higher peak (since the most recent `tracemalloc.start()` or
tracemalloc.clear_traces()` call).
I've used this recipe a couple times and the filename editing has always
been less than useful and something I've removed. This is because many
modules end up losing which package they are located in, e.g. `util/date.py`.
Add a total_nframe field to the traces collected by the tracemalloc module.
This field indicates the original number of frames before it was truncated.
* Add most_recent_first parameter to tracemalloc.Traceback.format to allow
reversing the order of the frames in the output
* Reversed default sorting of tracemalloc.Traceback frames
* Allowed negative limit, truncating from the other side.
* Make PyTraceMalloc_Track() and PyTraceMalloc_Untrack() functions
public (remove the "_" prefix)
* Remove the _PyTraceMalloc_domain_t type: use directly unsigned
int.
* Document methods
Note: methods are already tested in test_tracemalloc.
* Wrong parameter name, 'group_by' instead of 'key_type'
* Don't round up numbers when explaining the examples. If they exactly match
what can be read in the script output, it is to easier to understand
(4.8 MiB vs 4855 KiB)
* Fix incorrect method link that was pointing to another module
Patch written by Loic Pefferkorn.
Issue #26588:
* The _tracemalloc now supports tracing memory allocations of multiple address
spaces (domains).
* Add domain parameter to tracemalloc_add_trace() and
tracemalloc_remove_trace().
* tracemalloc_add_trace() now starts by removing the previous trace, if any.
* _tracemalloc._get_traces() now returns a list of (domain, size,
traceback_frames): the domain is new.
* Add tracemalloc.DomainFilter
* tracemalloc.Filter: add an optional domain parameter to the constructor and a
domain attribute
* Sublte change: use Py_uintptr_t rather than void* in the traces key.
* Add tracemalloc_config.use_domain, currently hardcoded to 1
* Various sections were pointing to the section on the string.Formatter
class, when the section on the common format string syntax is probably more
appropriate
* Fix references to various format() functions and methods
* Nested replacement fields may contain conversions and format specifiers,
and this is tested; see Issue #19729 for instance
The concept of .pyo files no longer exists. Now .pyc files have an
optional `opt-` tag which specifies if any extra optimizations beyond
the peepholer were applied.
