* bpo-30618: add readlink to pathlib.Path (GH-8285)Girts2019-10-231-0/+1
| | | | | | | | | | | This adds a "readlink" method to pathlib.Path objects that calls through to os.readlink. https://bugs.python.org/issue30618 Automerge-Triggered-By: @gpshead

* bpo-27657: Fix urlparse() with numeric paths (#661)Tim Graham2019-10-181-0/+2
| | | | | | | | | | * bpo-27657: Fix urlparse() with numeric paths Revert parsing decision from bpo-754016 in favor of the documented consensus in bpo-16932 of how to treat strings without a // to designate the netloc. * bpo-22891: Remove urlsplit() optimization for 'http' prefixed inputs.
* bpo-33604: Raise TypeError on missing hmac arg. (GH-16805)Gregory P. Smith2019-10-181-0/+3
| | | | | | | | | | Also updates the documentation to clarify the situation surrounding the digestmod parameter that is required despite its position in the argument list as of 3.8.0 as well as removing old python2 era references to "binary strings". We indavertently had this raise ValueError in 3.8.0 for the missing arg. This is not considered an API change as no reasonable code would be catching this missing argument error in order to handle it.

* bpo-13153: Use OS native encoding for converting between Python and Tcl. ↵Serhiy Storchaka2019-10-041-0/+4
| | | | | | | | | | | | | (GH-16545) On Windows use UTF-16 (or UTF-32 for 32-bit Tcl_UniChar) with the "surrogatepass" error handler for converting to/from Tcl Unicode objects. On Linux use UTF-8 with the "surrogateescape" error handler for converting to/from Tcl String objects. Converting strings from Tcl to Python and back now never fails (except MemoryError).

This bug has affected many people and in some cases has been a dealbreaker to the adoption of the otherwise wonderful pathlib and PEP519. https://stackoverflow.com/questions/33625931/copy-file-with-pathlib-in-python. This adds the outstanding test request from that PR @vstinner (https://github.com/python/cpython/pull/5393). Test fails without the change, passes with it, along with every other test in test_shutil.

I'm not sure if the idea is for all these modules to strictly avoid circular dependencies. They are already using os.path which is just as much a citizen in 3.8 as pathlib right? e.g. `real_dst = os.path.join(dst, _basename(src))` becomes `real_dst = Path(dst) / Path(src).name` I've looked around and familiarized myself, and I now think importing pathlib here is fine. My only remaining concern is that of performance. Here's the performance difference for this step. ``` In [46]: %timeit real_dst = os.path.join("a/b/c", _basename('b/')) 2.71 µs ± 62.6 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each) In [47]: %timeit real_dst = Path("a/b/c") / Path('b/').name 12.4 µs ± 65.3 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each) ``` Is 10us significant or insignificant compared to the least expensive operation this function will do? I don't know. Let's find out. ``` In [55]: %timeit os.rename('/tmp/a/a.txt', '/tmp/a/b.txt'); os.rename('/tmp/a/b.txt', '/tmp/a/a.txt') 124 µs ± 2.18 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each) ``` 62us to rename. 10us seems significant enough that we wouldn't want to favor the Path sugar suggestion. 16% speed decrease from adding the 10us. What do people think? I was hoping to get to use pathlib.Path here, but I suspect for this low level move, it should be as fast as possible, and 16% is not worth one line of sugary code to me. https://bugs.python.org/issue32689 Automerge-Triggered-By: @gvanrossum

| | | | | | | | | | Document that lnotab can contain invalid bytecode offsets (because of terrible reasons that are difficult to fix). Make dis.findlinestarts() ignore invalid offsets in lnotab. All other uses of lnotab in CPython (various reimplementations of addr2line or line2addr in Python, C and gdb) already ignore this, because they take an address to look for, instead. Add tests for the result of dis.findlinestarts() on wacky constructs in test_peepholer.py, because it's the easiest place to add them.
* bpo-38216, bpo-36274: Allow subclasses to separately override validation and ↵Jason R. Coombs2019-09-281-0/+4

Also, don't use the := operator to make backporting easier. * Add a news entry. * _prepare_path_encoding -> _encode_prepared_path() * Once again separate the path validation and request encoding, drastically simplifying the behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | * Raise the limit of maximum path depth to actual recursion limit * Add posibilities to adjust a path compiled in .pyc file. Now, you can: - Strip a part of path from a beggining of path into compiled file example "-s /test /test/build/real/test.py" → "build/real/test.py" - Append some new path to a beggining of path into compiled file example "-p /boo real/test.py" → "/boo/real/test.py" You can also use both options in the same time. In that case, striping is done before appending. * Add a possibility to specify multiple optimization levels Each optimization level then leads to separated compiled file. Use `action='append'` instead of `nargs='+'` for the -o option. Instead of `-o 0 1 2`, specify `-o 0 -o 1 -o 2`. It's more to type, but much more explicit. * Add a symlinks limitation feature This feature allows us to limit byte-compilation of symbolic links if they are pointing outside specified dir (build root for example).
