[issue24697] Add CoroutineReturn and CoroutineExit builtin exceptions for coroutines
Nick Coghlan added the comment: My initial inclination is to agree with Stefan. At the moment, we have a slightly leaky abstraction where the exceptions used mean that coroutines still expose the fact that under the covers they're defined in terms of generator semantics. However, that leak in the abstraction reveals an underlying truth - coroutine semantics *are* derived from generator semantics, and they *do* share common underlying infrastructure. We may eventually find pragmatic reasons for wanting to plug that leak and use separately named exceptions, but unlike the situation with coroutines themselves, I'm not currently seeing a clear gain in either usability or comprehensibility as a payoff for the extra complexity. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24697 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Re: problem with selecting remote procedure calls
- Original Message - From: Irmen de Jong irmen.nos...@xs4all.nl Eric, if you're concerned about performance, Pyro4 (the source distribution) comes with several examples that do simple performance related tests. You could run these and see what figures you get on your setup to see if it's anywhere acceptable, before even building anything with Pyro yourself. sounds like a plan. I managed to get around the initial problem I had because apparently the natlink extension for NaturallySpeaking is semi-persistent. Sometimes the statically created RPC connection would work, other times it wouldn't. The current workaround is to place the RPC connection initialization in the code that activates the grammar. blockquote Interesting project btw. /blockquote it has been a long time since a project like this has made me smile ear-to-ear. For example, yesterday I had to create twelve open VPN configuration files and key pairs. With broken hands like mine, it would be an extremely painful hour to two hours to entering the data over and over again even with easy RSA. I was able to complete this task in about 10 to 15 minutes. Now that's what accessibility is all about. I believe my experiment shows that a two dimensional grid with names for both rows and columns can allow a speech recognition dependent user much faster data entry than one could have with straight speech recognition. With some enhancements, it should be possible to use this technique to remember something on the fly. ideally I'd like to take a tool like treesheets , put some Python power underneath the grid, and explore how a grid tool can help accessibility but I'd need a volunteer to make that happen. -- https://mail.python.org/mailman/listinfo/python-list

ANN: decorator-4.0.0 released
The decorator module is over ten years old, but still alive and kicking. It is used by several frameworks and has been stable for a long time. It is your best option if you want to preserve the signature of decorated functions in a consistent way across Python releases. Version 4.0 is fully compatible with the past, except for one thing: support for Python 2.4 and 2.5 has been dropped and now there is an unified code base for Python 2.6, 2.7, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5. You can download the new release from PyPI with the usual $ pip install decorator The source code and the documentation are on GitHub: https://github.com/micheles/decorator/blob/4.0.0/documentation.rst (for Python 2.X) https://github.com/micheles/decorator/blob/4.0.0/documentation3.rst (for Python 3.X) What's new - Since now there is a single manual for all Python versions, I took the occasion for overhauling the documentation. Therefore, even if you are an old time user, you may want to read the docs again, since several examples have been improved. The packaging has been improved and I am distributing the code in wheel format too. The integration with setuptools has been improved and now you can use ``python setup.py test`` to run the tests. A new utility function ``decorate(func, caller)`` has been added, doing the same job that in the past was done by ``decorator(caller, func)``. The old functionality is still there for compatibility sake, but it is deprecated and not documented anymore. Apart from that, there is a new experimental feature. The decorator module now includes an implementation of generic (multiple dispatch) functions. The API is designed to mimic the one of ``functools.singledispatch`` (introduced in Python 3.4) but the implementation is much simpler; moreover all the decorators involved preserve the signature of the decorated functions.

[issue24699] TemporaryDirectory is cleaned up twice
Robert Collins added the comment: I think you may need to instrument TemporaryDirectory._cleanup to be sure, but it sounds like its being run twice. now, you're not using it like a context manager (at least as far as your code shows), so it must be happening from the weakref. https://docs.python.org/3/library/weakref.html#weakref.finalize is the relevant docs for that. The code looks ok as long as finalize triggers once and only once. Perhaps it should call the finalize() rather than manually calling _cleanup, in cleanup, but I don't see that that should make much difference. I would have thought it a deliberate attempt to avoid some bit of code (e.g. the resource warning), but since its a shared helper, thats not it. And finalize._exitfunc looks entirely sane to me. So - I suggest adding a call to print_stack in TemporaryDirectory._cleanup, to see the entire stack, and then hopefully we'll see two such printouts when this error happens, and be able to pinpoint how it's being called twice. -- nosy: +rbcollins ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24699 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Does the postgresql server and my archivedb reside globally or are they inside my archivedb virtual environment. I think globally. Your virtual environment is a Python construct only. That's where Python packages get installed, so if you don't activate it, you might not be able to use psycopg2, but as you surmise, the database itself is elsewhere on the system. To get pgAdmin3 to work, I have to have it set so that it logs in as gary ( no choice with this) and set group to root. Then in application advanced options set run as different user to root. This assumes that you are using a KDE4 desktop and have these option by right clicking the icons. pgAdmin3 data: Server Group Server(1) archivedb |_ Host name - 127.0.0.1 |_ username - archive |_ connected - no Archivedb requires a password to go deeper and takes the xx password that is in the django settings.py file. This opens up access to archivedb and lists archivedb Schema(1) public tables(10). At this point I found that all of the sequences and all of the tables are owned by root. This is probably the root (no pun intended) cause. Now what do I do about it. I'm not sure how this came about so don't know how to fix it. Ah, all owned by root. Okay! I've never actually tried this, but you might be able to directly reassign a bunch of things: http://www.postgresql.org/docs/9.4/static/sql-reassign-owned.html Make sure you have a backup. Reassigning root in this way is quite possibly a bad idea. If there aren't too many tables, you could use ALTER TABLE: http://www.postgresql.org/docs/9.4/static/sql-altertable.html ALTER TABLE tablename OWNER TO archives; But in theory, you shouldn't need to worry about owners at all - just make sure permissions are all assigned. Which you have done. So it's entirely possible none of this will change anything. :( Worst case, you may need to do an SQL dump of the entire database, then check the export, make sure ownership is correct, and reimport into a brand new database. Tedious, but it's certain to fix the problem. ChrisA pgAdmin3 showed two potential problems. The first connection listed in pg_hba.conf was: local all postgres radius. I removed this line so that the first line would be: local all all trust. Since all connections will be handled through Django? there should not be a problem with keeping loose security at this point. The second problem was that all fo the sequence and table files in archivedb showed the owner to be root. I changed them all to archive - the user listed in Django's settings.py file. Python manage.py migrate now works with no errors. Thank you for your help. I found an O'Reilly book - PosgreSQL Up Running, 2nd Edition, by Regina Obe and Leo Hsu that is very good. If I had read the book first, I would have avoided some of these problems. One of the things that I have found very frustrating is that most of the documentation is too compartmentalized. If an author is writing about Django they get sloppy with the database setup and visa versa. It now seems to me that: Postgresql should be set up first, the setup being completely disconnected from the Python / Django project All communication with the database will pass through Django with the exception of admin maintenance.

[issue24685] collections.OrderedDict collaborative subclassing
Eric Frederich added the comment: I understand that in the general case you cannot just swap the order around and get the same behaviour. This LoggingDict just prints some stuff to the screen and delegates to super and so I believe it should work wherever it is placed in a cooperative hierarchy. Do you agree? Now, I understand that OrderedDict is not cooperative. You stated that this is a design decision and I respect that choice, but you also stated that classes can be made to be cooperative by creating a wrapper. The reason I re-opened this bug is because I fail to see a way in which to create such a wrapper for Python3. Do you believe that it should be possible to create a cooperative wrapper? If it is possible (and its just my inability to create one) then I have no issue and the bug should be closed. If it is not possible, then perhaps it could be noted somewhere that its not cooperative and impossible to make it cooperative and it should be listed last when using multiple inheritance. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24685 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Re: 42**1000000 is CPU time free
As you are doing an operation on a literal, Python is computing the value at import time, which occurs before your time.clock() calls run. Basically, what you really wrote in your code is: import time a = time.clock() 42000...00 # Replace the ... with zeros until you have the actual value. b = time.clock() The computation time is still being shown in the real and user times reported by the external call. Similarly, if you were to put time.clock() calls around the import statement, you would see the time there, for the first import statement (Python caches imports, so they generally only run once per instance). The first example can measure the time as you are using a variable, which bypasses Python's literal optimization.

exploited to write outside the bounds of the string buffer and potentially
achieve code execution. The issue can be triggered by performing a large
substitution that overflows the arithmetic used in mymemreplace() to calculate
the size of the new string:
static char *
mymemreplace(const char *str, Py_ssize_t len, /* input string */
const char *pat, Py_ssize_t pat_len, /* pattern string to
find */
const char *sub, Py_ssize_t sub_len, /* substitution string
*/
Py_ssize_t count, /* number of
replacements */
Py_ssize_t *out_len)
{
[...]
new_len = len + nfound*(sub_len - pat_len); Unchecked arithmetic can
overflow here.
if (new_len == 0) {
/* Have to allocate something for the caller to free(). */
out_s = (char *)PyMem_MALLOC(1);
if (out_s == NULL)
return NULL;
out_s[0] = '\0';
}
else {
assert(new_len 0);
new_s = (char *)PyMem_MALLOC(new_len); An allocation is performed
using overflowed value.
if (new_s == NULL)
return NULL;
out_s = new_s;
for (; count 0 len 0; --count) { Memory is copied to new_s
using len, which can be greater than the overflowed new_len value.
/* find index of next instance of pattern */
offset = mymemfind(str, len, pat, pat_len);
if (offset == -1)
break;
/* copy non matching part of input string */
memcpy(new_s, str, offset);
str += offset + pat_len;
len -= offset + pat_len;
/* copy substitute into the output string */
new_s += offset;
memcpy(new_s, sub, sub_len);
new_s += sub_len;
}
/* copy any remaining values into output string */
if (len 0)
memcpy(new_s, str, len);
}
[...]
}
The following script demonstrates the issue:
import strop
strop.replace(\x75*0xEAAA,\x75,AA*0x)
When run under a debugger, it produces the following exception:

ANN: tsWxGTUI_PyVx 0.0.0 (pre-alpha) has been released.
ANN: tsWxGTUI_PyVx 0.0.0 (pre-alpha) has been released. What is it? === tsWxGTUI_PyVx is a foundation for developing, operating and troubleshooting Python and Python Curses based application programs embedded in local and remote 32-/64-bit computer systems used to monitor and control mission critical equipment. The architecture features Python 2x Python 3x based Command Line Interfaces (CLI) and Python Curses-based wxPython-style, Graphical-Text User Interfaces (GUI). The tsWxGTUI_PyVx Application Programming Interface (API) for the CLI and GUI are identical for the Python 2x and Python 3x versions. There are only minor internal differences in the source code. With it, you get that cross-platform, pixel-mode wxPython feeling on character-mode 8-/16-color (xterm-family) non-color (vt100-family) terminals and terminal emulators. What's new in version 0.0.0? Though the repository is extractable from its zip file after download, only the two Site-Packages in its Source-Distribution are installable. The extensive engineering notebook documention and two Developer-Sand- boxes are not installable because they are provided only to facilitate software development, maintenance and troubleshooting. The two Site-Packages may be installed and verified via the approprite install commands: 1. Example for installing and verifying the Python 2.x site-package: a. cd ./tsWxGTUI_PyVx_Repository/SourceDistributions/ Site-Packages/tsWxGTUI_PyVx/Python-2x b. python2.7 setup.py install c. Follow the demonstration and test instructions in: ./tsWxGTUI_PyVx_Repository/Documents/Demo.txt 2. Example for installing and verifying the Python 3.x site-package: a. cd ./tsWxGTUI_PyVx_Repository/SourceDistributions/ Site-Packages/tsWxGTUI_PyVx/Python-3x b. python3.4 setup.py install c. Follow the demonstration and test instructions in: ./tsWxGTUI_PyVx_Repository/Documents/Demo.txt Features: = 1. Launching from command line interface mode 2. Frames, Dialogs, Scrolled Windows 3. Panels 4. Buttons, CheckBoxes, Radio Boxes/Buttons 5. Text Entry and Password Entry (still under development) 6. Splash Screen display constructed or re-used during launch 7. 68-color palette (mapped into 8-/16-color Curses palette) 8. Logging to Screen and Files 9. Event Handling (not yet general purpose) 10. Task Bar (not yet capable of changing focus) 11. Position and dimensions accepted in Pixel (default) or Character (option) cell units. Capabilities: = 1. A library of general-purpose, re-usable building block modules for embedded systems. The building blocks: a. Provides both Command Line and Graphical-style User Interfaces that enable application developers to focus on the application specific functionality and not waste effort reinventing the functionality typical of Command Line and Graphical User Interfaces. b. Can operate in an isolated system (Stand-Alone mode) or in a networked system (Stand-Among mode). c. Are implemented in Python 2.x. d. Are ported to Python 3.x using a Python program (2to3) which reads Python 2.x source code and applies a series of fixers to transform it into valid Python 3.x code. Debugging of the Python 3.x code may be required to identify and resolve such runtime issues as decoding the type of data returned by Python curses modules. 2. Cross-platform designs run, without change, on Linux, Mac OS X and Microsoft Windows (the latter requires Cygwin, a Linux-like command line interface and GNU tool add-on from Red Hat). 3. Command Line Interface includes building blocks that create a sophisticated POSIX-/ Unix-like terminal interface. It features: a. Command line keyword/value pair option and positional argument parsing (using the most recent Python argparse, optparse or getopt package that is available). Default parser supports typical options: -h/--help, -a/--about, -d/--debug, -v/--version -V/--Verbose; b. Error/exception handling displays messages on console and returns Unix-style 8-bit exit code to coordinate a sequence of multiple applications. c. Event logging to application designated terminals, files or devices. d. Launching, event dispatching and terminating of the Graphical-style User Interface. e. Wrapper used to ensure that each application termin- ates with the exit code and message appropriate for co-ordination of a sequence of multiple applications. f. Tool to scan an operator designated directory tree and strip lines of source code of any superfluous trailing blank characters. g. Tool to create a copy of an operator designated directory tree after stripping comments and doc strings from Python source code to reduce required

ANN: Scipy 0.16.0 release
Hi all, On behalf of the Scipy development team I'm pleased to announce the availability of Scipy 0.16.0. This release contains some exciting new features (see release notes below) and more than half a years' worth of maintenance work. 93 people contributed to this release. This release requires Python 2.6, 2.7 or 3.2-3.4 and NumPy 1.6.2 or greater. Sources, binaries and release notes can be found at https://github.com/scipy/scipy/releases/tag/v0.16.0 Enjoy, Ralf -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 == SciPy 0.16.0 Release Notes == SciPy 0.16.0 is the culmination of 7 months of hard work. It contains many new features, numerous bug-fixes, improved test coverage and better documentation. There have been a number of deprecations and API changes in this release, which are documented below. All users are encouraged to upgrade to this release, as there are a large number of bug-fixes and optimizations. Moreover, our development attention will now shift to bug-fix releases on the 0.16.x branch, and on adding new features on the master branch. This release requires Python 2.6, 2.7 or 3.2-3.4 and NumPy 1.6.2 or greater. Highlights of this release include: - - A Cython API for BLAS/LAPACK in `scipy.linalg` - - A new benchmark suite. It's now straightforward to add new benchmarks, and they're routinely included with performance enhancement PRs. - - Support for the second order sections (SOS) format in `scipy.signal`. New features Benchmark suite - --- The benchmark suite has switched to using `Airspeed Velocity http://spacetelescope.github.io/asv/`__ for benchmarking. You can run the suite locally via ``python runtests.py --bench``. For more details, see ``benchmarks/README.rst``. `scipy.linalg` improvements - --- A full set of Cython wrappers for BLAS and LAPACK has been added in the modules `scipy.linalg.cython_blas` and `scipy.linalg.cython_lapack`. In Cython, these wrappers can now be cimported from their corresponding modules and used without linking directly against BLAS or LAPACK. The functions `scipy.linalg.qr_delete`, `scipy.linalg.qr_insert` and `scipy.linalg.qr_update` for updating QR decompositions were added. The function `scipy.linalg.solve_circulant` solves a linear system with a circulant coefficient matrix. The function `scipy.linalg.invpascal` computes the inverse of a Pascal matrix. The function `scipy.linalg.solve_toeplitz`, a Levinson-Durbin Toeplitz solver, was added. Added wrapper for potentially useful LAPACK function ``*lasd4``. It computes the square root of the i-th updated eigenvalue of a positive symmetric rank-one modification to a positive diagonal matrix. See its LAPACK documentation and unit tests for it to get more info. Added two extra wrappers for LAPACK least-square solvers. Namely, they are ``*gelsd`` and ``*gelsy``. Wrappers for the LAPACK ``*lange`` functions, which calculate various matrix norms, were added. Wrappers for ``*gtsv`` and ``*ptsv``, which solve ``A*X = B`` for tri-diagonal matrix ``A``, were added. `scipy.signal` improvements - --- Support for second order sections (SOS) as a format for IIR filters was added. The new functions are: * `scipy.signal.sosfilt` * `scipy.signal.sosfilt_zi`, * `scipy.signal.sos2tf` * `scipy.signal.sos2zpk` * `scipy.signal.tf2sos` * `scipy.signal.zpk2sos`. Additionally, the filter design functions `iirdesign`, `iirfilter`, `butter`, `cheby1`, `cheby2`, `ellip`, and `bessel` can return the filter in the SOS format. The function `scipy.signal.place_poles`, which provides two methods to place poles for linear systems, was added. The option to use Gustafsson's method for choosing the initial conditions of the forward and backward passes was added to `scipy.signal.filtfilt`. New classes ``TransferFunction``, ``StateSpace`` and ``ZerosPolesGain`` were added. These classes are now returned when instantiating `scipy.signal.lti`. Conversion between those classes can be done explicitly now. An exponential (Poisson) window was added as `scipy.signal.exponential`, and a Tukey window was added as `scipy.signal.tukey`. The function for computing digital filter group delay was added as `scipy.signal.group_delay`. The functionality for spectral analysis and spectral density estimation has been significantly improved: `scipy.signal.welch` became ~8x faster and the functions `scipy.signal.spectrogram`, `scipy.signal.coherence` and `scipy.signal.csd` (cross-spectral density) were added. `scipy.signal.lsim` was rewritten - all known issues are fixed, so this function can now be used instead of ``lsim2``; ``lsim`` is orders of magnitude faster than ``lsim2`` in most cases. `scipy.sparse` improvements - --- The function `scipy.sparse.norm`, which computes sparse matrix norms, was added. The function `scipy.sparse.random`, which allows to draw random variates

[issue24711] Document getpass.getpass behavior on ^C
New submission from Markus Unterwaditzer: getpass.getpass doesn't enter a newline when the user aborts input with ^C, while input/raw_input does. This behavior is surprising and can lead to mis-formatting of subsequent output. However, since this behavior exists since 2.7 and applications may have started to rely on it, I'd add a note to the documentation. -- assignee: docs@python components: Documentation messages: 247302 nosy: docs@python, untitaker priority: normal severity: normal status: open title: Document getpass.getpass behavior on ^C versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4, Python 3.5, Python 3.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24711 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

scalar vs array and program control
Hello, I'm fairly new to Python, struggling to write in a more object-oriented, functional style. I just wrote a function that takes two arrays representing sine (y) and cosine (x) angle coordinates, and returns the angle in degrees. I had initially written the function to take array-like arguments x/y, but I'd like to generalize and take scalars as well. However, the function has a subsetting operations, which don't work with scalars: vmag = np.sqrt((x ** 2) + (y ** 2)) ang = np.arctan2(y, x) ang[ang 0] = ang[ang 0] + (2 * np.pi) # output range 0 - 2*pi ang[vmag == 0] = 0 # when magnitude is 0 the angle is also 0 ang[ang == 0] = 2 * np.pi # convention If I want to take scalars x/y, I naively thought about implementing an if/else statement right before the subsetting operations. However, my intuition tells me there must be a proper object-oriented solution to this. Any tips appreciated. Cheers, -- Seb -- https://mail.python.org/mailman/listinfo/python-list
