ANN: Django-Compat-Patcher0.4
by Pascal Chambon 20 Jan '19

20 Jan '19

Dear pythoneers, I'm pleased to announce version 0.4 Django-Compat-Patcher, which adds forwards/backwards compatibility shims for Django1.10 and Django 1.11: https://pypi.org/manage/project/django-compat-patcher/release/0.4/ The goal of this project is to vastly improve the compatibility of different Django versions, so that different applications and plugins of its ecosystem can be used together without creating dependency hells. Django-Compat-Patcher also showcases a shim management system which could be ported to other frameworks, to separate compatibility shims from (clean) codebase, and apply them automatically only when needed. It has been used successfully on the Pychronia roleplay portal (https://github.com/ChrysalisTeam/pychronia).

ANN: RsFile 2.2 released
by Pascal Chambon 20 Jan '19

20 Jan '19

Dear pythoneers, I'm pleased to announce version 2.2 of RSFile I/O Library, which adds support for python3.6 and python3.7, and fixes some corner cases when using PIPEs. RSFile provides pure-python drop-in replacements for the classes of the io module, and for the open() builtin. Its goal is to provide a cross-platform, reliable, and comprehensive synchronous file I/O API, with advanced features like fine-grained opening modes, shared/exclusive file record locking, thread-safety, cache synchronization, file descriptor inheritability, and handy stat getters (size, inode, times…). Locking is performed using actual file record locking capabilities of the OS, not by using separate files/directories as locking markers, or other fragile gimmicks. Unix users might particularly be interested by the workaround that this library provides, concerning the weird semantic of fcntl() locks (when any descriptor to a disk file is closed, the process loses ALL locks acquired on this file through any descriptor). Possible use cases for this library: concurrently writing to logs without ending up with garbled data, manipulating sensitive data like disk-based databases, synchronizing heterogeneous producer/consumer processes when multiprocessing semaphores aren’t an option… Tested on python2.7 and python3.5+, on windows and unix-like systems. Should work with IronPython/Jython/PyPy too, since it uses stdlib utilities and ctypes bridges. regards, Pascal Chambon

NumPy 1.16.0 released.
by Charles R Harris 14 Jan '19

14 Jan '19

Hi All, On behalf of the NumPy team I'm pleased to announce the release of NumPy 1.16.0. This is the last NumPy release to support Python 2.7 and will be maintained as a long term release with bug fixes until 2020. This release has seen a lot of refactoring and features many bug fixes, improved code organization, and better cross platform compatibility. Not all of these improvements will be visible to users, but they should help make maintenance easier going forward. Highlights are Experimental support for overriding numpy functions in downstream projects. - The matmul function is now a ufunc and can be overridden using __array_ufunc__. - Improved support for the ARM, POWER, and SPARC architectures. - Improved support for AIX and PyPy. - Improved interoperation with ctypes. - Improved support for PEP 3118. The supported Python versions are 2.7 and 3.5-3.7, support for 3.4 has been dropped. The wheels on PyPI are linked with OpenBLAS v0.3.4+, which should fix the known threading issues found in previous OpenBLAS versions. Downstream developers building this release should use Cython >= 0.29.2 and, if linking OpenBLAS, OpenBLAS > v0.3.4. Wheels for this release can be downloaded from PyPI <https://pypi.org/project/numpy/1.16.0/>, source archives are available from Github <https://github.com/numpy/numpy/releases/tag/v1.16.0>. *Contributors* A total of 113 people contributed to this release.

wxPython 4.0.4
by Robin Dunn 06 Jan '19

06 Jan '19

Announcing wxPython 4.0.4 ========================= PyPI: https://pypi.org/project/wxPython/4.0.4 Extras: https://extras.wxPython.org/wxPython4/extras/ Pip: ``pip install wxPython==4.0.4`` Changes in this release include the following: * Fixed an issue where wx.lib.intctrl would erroneously attempt to use long on Python3. (#898) * Include the MSVC runtime DLLs for Python 3.7 builds too. * Clear LIBPATH_PYEXT and LIB_PYEXT for linux builds too. (#904) * Added a dependency on the Pillow package since it's used in some wx.lib.agw modules. (PR #908) * Add flag to hide page in wx.lib.agw.aui.notebook. (#895) * Switch wx.lib.plot to issue deprecation warnings with PlotPendingDeprecation so it doesn't have to enable all warnings to get them to be shown by default. (#902) * Added a Python 3.7 builder on Fedora 28. (#925) * Fix the object ownership transfer for wx.Menu.Insert() (#931) * Added wx.Treebook.GetTreeCtrl, wx.Listbook.GetListView and wx.Choicebook.GetChoiceCtrl. (#918) * Removed the wx.BookCtrlBase.RemovePage workaround as it was causing problems and doesn't seem to be necessary any more. The existing wxWidgets assertions are catching the out of range error just fine, however if wxWidgets was built without the debug helpers turned on then it could still cause a crash. (#888) * Reverted the changes which removed the content of the wx.lib.pubsub package and encouraged users to switch to the real PyPubSub package instead. Removing it caused more issues than were expected so it has been restored and the code updated to PyPubSub v3.3.0. Version 4.0.0 is available upstream, but it is not compatible with Python 2.7. Now, wx.lib.pubsub is actually deprecated instead of just trying to pass control over to the upstream PyPubSub library. (#932) * Improve calltip stability in pyshell. (#941) * Fix TypeError in wx.lib.throbber. (#924) * Fix missing parameter tool_id in wx.lib.agw.ribbon.toolbar.RibbonToolBar.AddToggleTool. (#947) * Add a step to wx.Config.ReadInt to attempt converting from long to int under python2. (#384) * Add virtual behavior for wx.RichTextCtrl and wx.TextCtrl's Copy/Cut/Paste methods and their Can* counterparts. (#954) * Fix IO type in wx.lib.agw.thumbnailctrl (#959) * Fix type error that would occur using pycolourchooser. (#957) * Optimize line drawing in HyperTreeList. (#973) * Add wrapper for wx.StaticBox.GetBordersForSizer and use it in the demo to do platform-specific layout of the items in the StaticBox. (#974) * Update wx.Point, wx.RealPoint, and wx.Size to use floating point arithmetic when conducting scalar multiplication (#971) * Fix load/save bugs in PySlices (PR#978) * Replace deprecated PIL.Image.tostring (PR#1005) * Fix rendering and mouse sensitivity in UltimateListCtrl when adding HyperText items. (#1010) * Added a parameter to lib.agw.CustomTreeCtrl.SetItemWindow(), to allow positioning the Window (a small image) on the left of text in a CustomTreeItem. (#PR886). * Declared DeleteAllPages in the notebook subclasses, so the proper C++ implementation will be called. (#972) * Removed wx.lib.floatbar, which has been deprecated forever and probably hasn't been working in nearly as long. (#976) * Updated SIP to version 4.19.13. * Fix an issue in wx.lib.agw.aui.AuiManager where the orientation of an AuiToolBar would not be updated when calling LoadPerspective. (#917) * Fixed a bug in wx.FileSystemHandler.OpenFile where the object ownership was not being transferred correctly, causing a crash after a premature object deletion. (#926) * Fixed wx.ListCtrl.Append when wx.LC_SORT style is used, so appending items out of order does not lose the data for the remaining columns. (#906) * Add wx.Accessible, it's Windows-only, will raise a NotImplementedError exception on the other platforms. (#958) * Added the ability to generate stub classes for use when optional wxWidgets features are not part of the build. So far, stubs are available for wx.Accessible, wx.FileSystemWatcher, wx.glcanvas, wx.media and wx.html2. * Moved the wxpy_api.h file into the wx package at wx/include/wxPython so it will be included in the wheel file. (#961) * Fixed how string data is added to a virtual file-like object in wx.MemoryFSHandler. All strings are now added to the file as utf-8 encoded data, in both Python2 and Python3, and will be read from the virtual file the same way. If you need to use some other encoding for some reason you can first convert the text to a bytesarray or other buffer protocol compatible object and then create the virtual file from that data. (#969) * Performance update for wx.lib.agw.customtreectrl (#1049) * Ensure that colours set in wx.lib.agw.customtreectrl.TreeItemAttr are instances of wx.Colour. (#1032) * Fix drawing of ticks in wx.lib.agw.speedmeter when there are negative bounds values. (#1013) * wxWidgets for Mac includes the wxJoystick class now, also update the demo. (#997) * Fix wx.html.HtmlPrintout to not be seen as an abstract class, so it can be instantiated. (#1060) * Fix wx.aui.AuiNotbook.SetArtProvider to properly transfer ownership of the art object from Python to C++. This possible double-deletion and related crashing problems. (#1061) * Fixed the wrappers for wx.html.HtmlWindow.OnOpeningURL to properly handle the redirect output parameter. (#1068) This is a backwards-incompatible change, please see the Migration Guide for details. * TabNavigatorWindow works similarly to other programs now. It's resizable and draggable so if user has tons of files with long names, it isn't an irritation anymore plastered right in the middle of the screen and can't be worked with easily and ESC now cancels the popup with a proper returnId. (#1096) * Added missing methods in wx.ListBox, SetItemForegroundColour, SetItemBackgroundColour and SetItemFont. (#1095) * Backported a fix in wxWidgets that avoids crashing in hhctrl.ocx when using context sensitive help in 64-bit builds on Windows. (#1104) What is wxPython? ----------------- wxPython is a cross-platform GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a set of Python extension modules that wrap the GUI components of the popular wxWidgets cross platform library, which is written in C++. Supported platforms are Microsoft Windows, Mac OS X and macOS, and Linux or other unix-like systems with GTK2 or GTK3 libraries. In most cases the native widgets are used on each platform to provide a 100% native look and feel for the application. What is wxPython Phoenix? ------------------------- wxPython's Project Phoenix is a new from-the-ground-up implementation of wxPython, created with the intent of making wxPython “better, stronger, faster than he was before.” In other words, this new implementation is focused on improving speed, maintainability and extensibility of wxPython, as well as removing most of the cruft that had accumulated over the long life of Classic wxPython. The project has been in development off and on, mostly behind the scenes, for many years. For the past few years automated snapshot builds have been available for those adventurous enough to try it, and many people eventually started using the snapshots in their projects, even for production releases. While there are still some things on the periphery that need to be completed, the core of the new wxPython extension modules which wrap the wxWidgets code has been stable for a long time now. Due to some things being cleaned up, reorganized, simplified and dehackified wxPython Phoenix is not completely backwards compatible with wxPython Classic. This is intended. In general, however, the API differences tend to be minor and some applications can use Phoenix with slight, or even with no modifications. In some other cases the correct way to do things was also available in Classic and it's only the wrong way that has been removed from Phoenix. For more information there is a Migration Guide document available at: https://docs.wxpython.org/MigrationGuide.html The new wxPython API reference documentation, including all Python-specific additions and customizations, and docs for the wx.lib package, is located at: https://docs.wxpython.org/ -- Robin Dunn Software Craftsman http://wxPython.org
