Changelog for PyInstaller

3.6 (2020-01-09)

Important: This is the last release of PyInstaller supporting Python 2.7. Python 2 is end-of-life, many packages are about to drop support for Python 2.7 - or already did it.

Security

  • [SECURITY] (Win32) Fix CVE-2019-16784: Local Privilege Escalation caused by insecure directory permissions of sys._MEIPATH. This security fix effects all Windows software frozen by PyInstaller in “onefile” mode. While PyInstaller itself was not vulnerable, all Windows software frozen by PyInstaller in “onefile” mode is vulnerable.

    If you are using PyInstaller to freeze Windows software using “onefile” mode, you should upgrade PyInstaller and rebuild your software.

Features

  • (Windows): Applications built in windowed mode have their debug messages sent to any attached debugger or DebugView instead of message boxes. (#4288)

  • Better error message when file exists at path we want to be dir. (#4591)

Bugfix

  • (Windows) Allow usage of VSVersionInfo as version argument to EXE again. (#4381, #4539)

  • (Windows) Fix MSYS2 dll’s are not found by modulegraph. (#4125, #4417)

  • (Windows) The temporary copy of bootloader used add resources, icons, etc. is not created in –workpath instead of in %TEMP%. This fixes issues on systems where the anti-virus cleans %TEMP% immediatly. (#3869)

  • Do not fail the build when ldconfig is missing/inoperable. (#4261)

  • Fixed loading of IPython extensions. (#4271)

  • Fixed pre-find-module-path hook for distutils to be compatible with virtualenv >= 16.3. (#4064, #4372)

  • Improve error reporting when the Python library can’t be found. (#4162)

Hooks

  • Add hook for avro (serialization and RPC framework) (#4388), django-babel (#4516), enzyme (#4338), google.api (resp. google.api.core) (#3251), google.cloud.bigquery (#4083, #4084), google.cloud.pubsub (#4446), google.cloud.speech (#3888), nnpy (#4483), passlib (#4520), pyarrow (#3720, #4517), pyexcel and its plugins io, ods, ods3, odsr, xls, xlsx, xlsxw (#4305), pysnmp (#4287), scrapy (#4514), skimage.io (#3934), sklearn.mixture (#4612), sounddevice on macOS and Windows (#4498), text-unidecode (#4327, #4530), the google-cloud-kms client library (#4408), ttkwidgets (#4484), and webrtcvad (#4490).

  • Correct the location of Qt translation files. (#4429)

  • Exclude imports for pkg_resources to fix bundling issue. (#4263, #4360)

  • Fix hook for pywebview to collect all required libraries and data-files. (#4312)

  • Fix hook numpy and hook scipy to account for differences in location of extra dlls on Windows. (#4593)

  • Fix pysoundfile hook to bundle files correctly on both OSX and Windows. (#4325)

  • Fixed hook for pint to also copy metadata as required to retrieve the version at runtime. (#4280)

  • Fixed PySide2.QtNetwork hook by mirroring PyQt5 approach. (#4467, #4468)

  • Hook for pywebview now collects data files and dynamic libraries only for the correct OS (Windows). Hook for pywebview now bundles only the required ‘lib’ subdirectory. (#4375)

  • Update hooks related to PySide2.QtWebEngineWidgets, ensure the relevant supporting files required for a QtWebEngineView are copied into the distribution. (#4377)

  • Update PyQt5 loader to support PyQt >=5.12.3. (#4293, #4332)

  • Update PyQt5 to package 64-bit SSL support DLLs. (#4321)

  • Update PyQt5 to place OpenGL DLLs correctly for PyQt >= 5.12.3. (#4322)

  • (GNU/Linux) Make hook for GdkPixbuf compatible with Ubuntu and Debian (#4486).

Bootloader

  • (OSX): Added support for appending URL to program arguments when applications is launched from custom protocol handler. (#4397, #4399)

  • (POSIX) For one-file binaries, if the program is started via a symlink, the second process now keeps the basename of the symlink. (#3823, #3829)

  • (Windows) If bundled with the application, proactivley load ucrtbase.dll before loading the Python library. This works around unresolved symbol errors when loading python35.dll (or later) on legacy Windows (7, 8, 8.1) systems with Universal CRT update is not installed. (#1566, #2170, #4230)

  • Add our own implementation for strndup and strnlen to be used on pattforms one of these is missing.

PyInstaller Core

  • Now uses hash based .pyc files as specified in PEP 552 in base_library.zip when using Python 3.7 (#4096)

  • (MinGW-w64) Fix .rc.o file not found error. (#4501, #4586)

  • Add a check whether strndup and strnlen are available.

  • Added OpenBSD support. (#4545)

  • Fix build on Solaris 10.

  • Fix checking for compiler flags in configure phase. The check for compiler flags actually did never work. (#4278)

  • Update url for public key in update-waf script. (#4584)

  • Update waf to version 2.0.19.

3.5 (2019-07-09)

Features

  • (Windows) Force --windowed option if first script is a .pyw file. This might still be overwritten in the spec-file. (#4001)

  • Add support for relative paths for icon-files, resource-files and version-resource-files. (#3333, #3444)

  • Add support for the RedHat Software Collections (SCL) Python 3.x. (#3536, #3881)

  • Install platform-specific dependencies only on that platform. (#4166, #4173)

  • New command-line option --upx-exclude, which allows the user to prevent binaries from being compressed with UPX. (#3821)

Bugfix

  • (conda) Fix detection of conda/anaconda platform.

  • (GNU/Linux) Fix Anaconda Python library search. (#3885, #4015)

  • (Windows) Fix UAC in one-file mode by embedding the manifest. (#1729, #3746)

  • (Windows\Py3.7) Now able to locate pylib when VERSION.dll is listed in python.exe PE Header rather than pythonXY.dll (#3942, #3956)

  • Avoid errors if PyQt5 or PySide2 is referenced by the modulegraph but isn’t importable. (#3997)

  • Correctly parse the --debug=import, --debug=bootloader, and --debug=noarchive command-line options. (#3808)

  • Don’t treat PyQt5 and PySide2 files as resources in an OS X windowed build. Doing so causes the resulting frozen app to fail under Qt 5.12. (#4237)

  • Explicitly specify an encoding of UTF-8 when opening all text files. (#3605)

  • Fix appending the content of datas in a spec files to binaries instead of the internal datas. (#2326, #3694)

  • Fix crash when changing from --onefile to --onedir on consecutive runs. (#3662)

  • Fix discovery of Qt paths on Anaconda. (#3740)

  • Fix encoding error raised when reading a XML manifest file which includes non-ASCII characters. This error inhibited building an executable which has non-ASCII characters in the filename. (#3478)

  • Fix inputs to QCoreApplication constructor in Qt5LibraryInfo. Now the core application’s initialization and finalization in addition to system-wide and application-wide settings is safer. (#4121)

  • Fix installation with pip 19.0. (#4003)

  • Fixes PE-file corruption during version update. (#3142, #3572)

  • In the fake ´site` module set USER_BASE to empty string instead of None as Jupyter Notebook requires it to be a ‘str’. (#3945)

  • Query PyQt5 to determine if SSL is supported, only adding SSL DLLs if so. In addition, search the path for SSL DLLs, instead of looking in Qt’s BinariesPath. (#4048)

  • Require pywin32-ctypes version 0.2.0, the minimum version which supports Python 3.7. (#3763)

  • Use pkgutil instead of filesystem operations for interacting with the modules. (#4181)

Incompatible Changes

  • PyInstaller is no longer tested against Python 3.4, which is end-of-live.

  • Functions compat.architecture(), compat.system() and compat.machine() have been replace by variables of the same name. This avoids evaluating the save several times.

  • Require an option for the --debug argument, rather than assuming a default of all. (#3737)

Hooks

Bootloader

  • Update bundled zlib library to 1.2.11 address vulnerabilities. (#3742)

Documentation

  • Update the text produced by --help to state that the --debug argument requires an option. Correctly format this argument in the Sphinx build process. (#3737)

Project & Process

  • Remove the PEP-518 “build-system” table from pyproject.toml to fix installation with pip 19.0.

PyInstaller Core

  • Add support for folders in COLLECT and BUNDLE. (#3653)

  • Completely remove pywin32 dependency, which has erratic releases and the version on pypi may no longer have future releases. Require pywin32-ctypes instead which is pure python. (#3728, #3729)

  • modulegraph: Align with upstream version 0.17.

  • Now prints a more descriptive error when running a tool fails (instead of dumping a trace-back). (#3772)

  • Suppress warnings about missing UCRT dependencies on Win 10. (#1566, #3736)

Test-suite and Continuous Integration

  • Fix Appveyor failures of test_stderr_encoding() and test_stdout_encoding() on Windows Python 3.7 x64. (#4144)

  • November update of packages used in testing. Prevent pyup from touching test/requirements-tools.txt. (#3845)

  • Rewrite code to avoid a RemovedInPytest4Warning: Applying marks directly to parameters is deprecated, please use pytest.param(..., marks=...) instead.

  • Run Travis tests under Xenial; remove the deprecated sudo: false tag. (#4140)

  • Update the Markdown test to comply with Markdown 3.0 changes by using correct syntax for extensions.

3.4 (2018-09-09)

Features

  • Add support for Python 3.7 (#2760, #3007, #3076, #3399, #3656), implemented by Hartmut Goebel.

  • Improved support for Qt5-based applications (#3439). By emulating much of the Qt deployment tools’ behavior most PyQt5 variants are supported. However, Anaconda’s PyQt5 packages are not supported because its QlibraryInfo implementation reports incorrect values. CI tests currently run on PyQt5 5.11.2. Many thanks to Bryan A. Jones for taking this struggle.

  • --debug now allows more debugging to be activated more easily. This includes bootloader messages, Python’s “verbose imports” and store collected Python files in the output directory instead of freezing. See pyinstaller –-help for details. (#3546, #3585, #3587)

  • Hint users to install development package for missing pyconfig.h. (#3348)

  • In setup.py specify Python versions this distribution is compatible with.

  • Make base_library.zip reproducible: Set time-stamp of files. (#2952, #2990)

  • New command-line option --bootloader-ignore-signals to make the bootloader forward all signals to the bundle application. (#208, #3515)

  • (OS X) Python standard library module plistlib is now used for generating the Info.plist file. This allows passing complex and nested data in info_plist. (#3532, #3541)

Bugfix

  • Add missing warnings module to base_library.zip. (#3397, #3400)

  • Fix and simplify search for libpython on Windows, msys2, cygwin. (#3167, #3168)

  • Fix incompatibility with pycryptodome (a replacement for the apparently abandoned pycrypto library) when using encrypted PYZ-archives. (#3537)

  • Fix race condition caused by the bootloader parent process terminating before the child is finished. This might happen e.g. when the child process itself plays with switch_root. (#2966)

  • Fix wrong security alert if a filename contains ... (#2641, #3491)

  • Only update resources of cached files when necessary to keep signature valid. (#2526)

  • (OS X) Fix: App icon appears in the dock, even if LSUIElement=True. (#1917, #2075, #3566)

  • (Windows) Fix crash when trying to add resources to Windows executable using the --resource option. (#2675, #3423)

  • (Windows) Only update resources when necessary to keep signature valid (#3323)

  • (Windows) Use UTF-8 when reading XML manifest file. (#3476)

  • (Windows) utils/win32: trap invalid --icon arguments and terminate with a message. (#3126)

Incompatible Changes

  • Drop support for Python 3.3 (#3288), Thanks to Hugo and xoviat.

  • --debug now expects an (optional) argument. Thus using … --debug script.py will break. Use … script.py --debug or … --debug=all script.py instead. Also --debug=all (which is the default if no argument is given) includes noarchive, which will store all collected Python files in the output directory instead of freezing them. Use --debug=bootloader to get the former behavior. (#3546, #3585, #3587)

  • (minor) Change naming of intermediate build files and the warn file. This only effects 3rd-party tools (if any exists) relying on the names of these files.

  • (minor) The destination path for --add-data and --add-binary must no longer be empty, use . instead. (#3066)

  • (minor) Use standard path, not dotted path, for C extensions (Python 3 only).

Hooks

Bootloader

  • Forward all signals to the child process if option pyi-bootloader-ignore-signals to be set in the archive. (#208, #3515)

  • Use waitpid instead of wait to avoid the bootloder parent process gets signaled. (#2966)

  • (OS X) Don’t make the application a GUI app by default, even in --windowed mode. Not enforcing this programmatically in the bootloader allows to control behavior using Info.plist options - which can by set in PyInstaller itself or in the .spec-file. (#1917, #2075, #3566)

  • (Windows) Show respectivly print utf-8 debug messages ungarbled. (#3477)

  • Fix setenv() call when HAVE_UNSETENV is not defined. (#3722, #3723)

Module Loader

  • Improved error message in case importing an extension module fails. (#3017)

Documentation

  • Fix typos, smaller errors and formatting errors in documentation. (#3442, #3521, #3561, #3638)

  • Make clear that --windowed is independent of --onedir. (#3383)

  • Mention imports using imports imp.find_module() are not detected.

  • Reflect actual behavior regarding LD_LIBRARY_PATH. (#3236)

  • (OS X) Revise section on info_plist for plistlib functionality and use an example more aligned with real world usage. (#3532, #3540, #3541)

  • (developers) Overhaul guidelines for commit and commit-messages. (#3466)

  • (developers) Rework developer’s quick-start guide.

Project & Process

  • Add a pip requirements.txt file.

  • Let pyup update package requirements for “Test – Libraries” every month only.

  • Use towncrier to manage the change log entries. (#2756, #2837, #3698)

PyInstaller Core

  • Add requirements_for_package() and collect_all() helper functions for hooks.

  • Add a explanatory header to the warn-file, hopefully reducing the number of those posting the file to the issue tracker.

  • Add module enum to base_library.zip, required for module re in Python 3.6 (and re is required by warnings).

  • Always write the warn file.

  • Apply format_binaries_and_datas() (which converts hook-style tuples into TOC-style tuples) to binaries and datas added through the hook api.

  • Avoid printing a useless exceptions in the get_module_file_attribute() helper function..

  • Don’t gather Python extensions in collect_dynamic_libc().

  • Fix several ResourceWarnings and DeprecationWarnings (#3677)

  • Hint users to install necessary development packages if, in format_binaries_and_datas(), the file not found is pyconfig.h. (#1539, #3348)

  • Hook helper function is_module_satisfies() returns False for packages not found. (#3428, #3481)

  • Read data for cache digest in chunks. (#3281)

  • Select correct file extension for C-extension file-names like libzmq.cp36-win_amd64.pyd.

  • State type of import (conditional, delayed, etc.) in the warn file again.

  • (modulegraph) Unbundle altgraph library, use from upstream. (#3058)

  • (OS X) In --console mode set LSBackgroundOnly=True in``Info.plist`` to hide the app-icon in the dock. This can still be overruled by passing info_plist in the .spec-file. (#1917, #3566)

  • (OS X) Use the python standard library plistlib for generating the Info.plist file. (#3532, #3541)

  • (Windows) Completely remove pywin32 dependency, which has erratic releases and the version on pypi may no longer have future releases. Require pywin32-ctypes instead, which is pure python. (#3141)

  • (Windows) Encode manifest before updating resource. (#3423)

  • (Windows) Make import compatible with python.net, which uses an incompatible signature for __import__. (#3574)

Test-suite and Continuous Integration

  • Add script and dockerfile for running tests in docker. (Contributed, not maintained) (#3519)

  • Avoid log messages to be written (and captured) twice.

  • Fix decorator skipif_no_compiler.

  • Fix the test for the “W” run-time Python option to verify module warnings can actually be imported. (#3402, #3406)

  • Fix unicode errors when not capturing output by pytest.

  • Run pyinstaller -h to verify it works.

  • test_setuptools_nspkg no longer modifies source files.

  • Appveyor:

    • Add documentation for Appveyor variables used to appveyor.yml.

    • Significantly clean-up appveyor.yml (#3107)

    • Additional tests produce > 1 hour runs. Split each job into two jobs.

    • Appveyor tests run on 2 cores; therefore, run 2 jobs in parallel.

    • Reduce disk usage.

    • Split Python 2.7 tests into two jobs to avoid the 1 hour limit.

    • Update to use Windows Server 2016. (#3563)

  • Travis

    • Use build-stages.

    • Clean-up travis.yml (#3108)

    • Fix Python installation on OS X. (#3361)

    • Start a X11 server for the “Test - Libraries” stage only.

    • Use target python interpreter to compile bootloader to check if the build tool can be used with that this Python version.

Bootloader build

  • Print invoking python version when compiling.

  • Update waf build-tool to 2.0.9 and fix our wscript for waf 2.0.

  • (GNU/Linux) When building with --debug turn of FORTIFY_SOURCE to ease debugging.

Known Issues

  • Anaconda’s PyQt5 packages are not supported because its QlibraryInfo implementation reports incorrect values.

  • All scripts frozen into the package, as well as all run-time hooks, share the same global variables. This issue exists since v3.2 but was discovered only lately, see #3037. This may lead to leaking global variables from run-time hooks into the script and from one script to subsequent ones. It should have effects in rare cases only, though.

  • Data-files from wheels, unzipped eggs or not ad egg at all are not included automatically. This can be worked around using a hook-file, but may not suffice when using --onefile and something like python-daemon.

  • The multipackage (MERGE) feature (#1527) is currently broken.

  • (OSX) Support for OpenDocument events (#1309) is broken.

  • (Windows) With Python 2.7 the frozen application may not run if the user-name (more specifically %TEMPDIR%) includes some Unicode characters. This does not happen with all Unicode characters, but only some and seems to be a windows bug. As a work-around please upgrade to Python 3 (#2754, #2767).

  • (Windows) For Python >= 3.5 targeting Windows < 10, the developer needs to take special care to include the Visual C++ run-time .dlls. Please see the section Platform-specific Notes in the manual. (#1566)

3.3.1 (2017-12-13)

Hooks

  • Fix imports in hooks accessible_output and sound_lib (#2860).

  • (aarch64) Use correct bootloader for 64-bit ARM (#2873).

  • (OS X) Fix replacement of run-time search path keywords (@… ) (#3100).

  • Modulegraph

    • Fix recursion too deep errors cause by reimporting SWIG-like modules (#2911, #3040, #3061).

    • Keep order of imported identifiers.

Test-suite and Continuous Integration

  • In Continuous Integration tests: Enable flake8-diff linting. This will refuse all changed lines not following PEP 8.

  • Enable parallel testing on Windows,

  • Update requirements.

  • Add more test cases for modulegraph.

  • Fix a test-case for order of module import.

  • Add test-cases to check scripts do not share the same global vars (see Known Issues).

Documentation

  • Add clarification about treatment of options when a spec-file is provided (#3039).

  • Add docs for running PyInstaller with Python optimizations (#2905).

Known Issues

  • All scripts frozen into the package, as well as all run-time hooks, share the same global variables. This issue exists since v3.2 but was discovered only lately, see #3037. This may lead to leaking global variables from run-time hooks into the script and from one script to subsequent ones. It should have effects in rare cases only, though.

  • Further see the Known Issues for release 3.3.

3.3 (2017-09-21)

  • Add Support for Python 3.6! Many thanks to xiovat! (#2331, #2341)

  • New command line options for adding data files (--datas, #1990) and binaries (--binaries, #703)

  • Add command line option ‘–runtime-tmpdir’.

  • Bootloaders for Windows are now build using MSVC and statically linked with the run-time-library (CRT). This solved a lot of issues related to .dlls being incompatible with the ones required by python.dll.

  • Bootloaders for GNU/Linux are now officially no LSB binaries. This was already the case since release 3.1, but documented the other way round. Also the build defaults to non-LSB binaries now. (#2369)

  • We improved and stabilized both building the bootloaders and the continuous integration tests. See below for details. Many thanks to all who worked on this.

  • To ease solving issues with packages included wrongly, the html-file with a cross-reference is now always generated. It’s visual appearance has been modernized (#2765).

Incompatible changes

  • Command-line option obsoleted several version ago are not longer handled gracefully but raise an error (#2413)

  • Installation: PyInstaller removed some internal copies of 3rd-party packages. These are now taken from their official releases at PyPI (#2589). This results in PyInstaller to no longer can be used from just an unpacked archive, but needs to be installed like any Python package. This should effect only a few people, e.g. the developers.

  • Following PEP 527, we only release one source archive now and decided to use .tar.gz (#2754).

Hooks

  • New and Updated hooks: accessible_output2 (#2266), ADIOS (#2096), CherryPy (#2112), PySide2 (#2471, #2744) (#2472), Sphinx (#2612, 2708) (#2708), appdir (#2478), clr (#2048), cryptodome (#2125), cryptography (#2013), dclab (#2657), django (#2037), django migrations (#1795), django.contrib (#2336), google.cloud, google.cloud.storage, gstreamer (#2603), imageio (#2696), langcodes (#2682), libaudioverse (#2709), mpl_toolkits (#2400), numba, llvmlite (#2113), openpyxl (#2066), pylint, pymssql, pyopencl, pyproj (#2677), pytest (#2119), qtawesome (#2617), redmine, requests (#2334), setuptools, setuptools (#2565), shapely (#2569), sound_lib (#2267), sysconfig, uniseg (#2683), urllib3, wx.rc (#2295),

      • Fix hooks for PyGObject on windows platform (#2306)

  • Fixed hooks: botocore (#2384), clr (#1801), gstreamer (#2417), h5py (#2686), pylint, Tix data files (#1660), usb.core (#2088), win32com on non-windows-systems (#2479)

  • Fix multiprocess spawn mode on POSIX OSs (#2322, #2505, #2759, #2795).

Bootloader

  • Add tempdir option to control where bootloader will extract files (#2221)

  • (Windows) Add workaround for a Python 3 issue http://bugs.python.org/issue29778 (#2496, #2844)

  • (OS X): Use single process for –onedir mode (#2616, #2618)

  • (GNU/Linux) Compile bootloaders with –no-lsb by default (#2369)

  • (GNU/Linux) Fix: linux64 bootloader requires glibc 2.14 (#2160)

  • (GNU/Linux) set_dynamic_library_path change breaks plugin library use (#625)

Bootloader build

The bootloader build was largely overhauled. In the wscript, the build no longer depends on the Python interpreter’s bit-size, but on the compiler. We have a machine for building bootloaders for Windows and cross-building for OS X. Thus all mainteriner are now able to build the bootloaders for all supported platforms.

Known Issues

  • Data-files from wheels, unzipped eggs or not ad egg at all are not included automatically. This can be worked around using a hook-file, but may not suffice when using --onefile and something like python-daemon.

  • The multipackage (MERGE) feature (#1527) is currently broken.

  • (OSX) Support for OpenDocument events (#1309) is broken.

  • (Windows) With Python 2.7 the frozen application may not run if the user-name (more specifically %TEMPDIR%) includes some Unicode characters. This does not happen with all Unicode characters, but only some and seems to be a windows bug. As a work-around please upgrade to Python 3 (#2754, #2767).

  • (Windows) For Python >= 3.5 targeting Windows < 10, the developer needs to take special care to include the Visual C++ run-time .dlls. Please see the section Platform-specific Notes in the manual. (#1566)

  • For Python 3.3, imports are not thread-safe (#2371#). Since Python 3.3 is end of live at 2017-09-29, we are not going to fix this.
