Continuing to produce them was a maintenance burden. +* Added support for Python 3.8, and removed support for Python 3.4. +* Add low level bindings for extracting the seed and the public key + from crypto_sign_ed25519 secret key +* Add low level bindings for deterministic random generation. +* Add ``wheel`` and ``setuptools`` setup_requirements in ``setup.py`` (#485) +* Fix checks on very slow builders (#481, #495) +* Add low-level bindings to ed25519 arithmetic functions +* Update low-level blake2b state implementation +* Fix wrong short-input behavior of SealedBox.decrypt() (#517) +* Raise CryptPrefixError exception instead of InvalidkeyError when trying + to check a password against a verifier stored in a unknown format (#519) +* Add support for minimal builds of libsodium. Trying to call functions + not available in a minimal build will raise an UnavailableError + exception. To compile a minimal build of the bundled libsodium, set + the SODIUM_INSTALL_MINIMAL environment variable to any non-empty + string (e.g. ``SODIUM_INSTALL_MINIMAL=1``) for setup. + +1.3.0 2018-09-26 +---------------- + +* Added support for Python 3.7. +* Update ``libsodium`` to 1.0.16. +* Run and test all code examples in PyNaCl docs through sphinx's + doctest builder. +* Add low-level bindings for chacha20-poly1305 AEAD constructions. +* Add low-level bindings for the chacha20-poly1305 secretstream constructions. +* Add low-level bindings for ed25519ph pre-hashed signing construction. +* Add low-level bindings for constant-time increment and addition + on fixed-precision big integers represented as little-endian + byte sequences. +* Add low-level bindings for the ISO/IEC 7816-4 compatible padding API. +* Add low-level bindings for libsodium's crypto_kx... key exchange + construction. +* Set hypothesis deadline to None in tests/test_pwhash.py to avoid + incorrect test failures on slower processor architectures. GitHub + issue #370 + +1.2.1 - 2017-12-04 +------------------ + +* Update hypothesis minimum allowed version. +* Infrastructure: add proper configuration for readthedocs builder + runtime environment. + +1.2.0 - 2017-11-01 +------------------ + +* Update ``libsodium`` to 1.0.15. +* Infrastructure: add jenkins support for automatic build of + ``manylinux1`` binary wheels +* Added support for ``SealedBox`` construction. +* Added support for ``argon2i`` and ``argon2id`` password hashing constructs + and restructured high-level password hashing implementation to expose + the same interface for all hashers. +* Added support for 128 bit ``siphashx24`` variant of ``siphash24``. +* Added support for ``from_seed`` APIs for X25519 keypair generation. +* Dropped support for Python 3.3. + +1.1.2 - 2017-03-31 +------------------ + +* reorder link time library search path when using bundled + libsodium + +1.1.1 - 2017-03-15 +------------------ + +* Fixed a circular import bug in ``nacl.utils``. + +1.1.0 - 2017-03-14 +------------------ + +* Dropped support for Python 2.6. +* Added ``shared_key()`` method on ``Box``. +* You can now pass ``None`` to ``nonce`` when encrypting with ``Box`` or + ``SecretBox`` and it will automatically generate a random nonce. +* Added support for ``siphash24``. +* Added support for ``blake2b``. +* Added support for ``scrypt``. +* Update ``libsodium`` to 1.0.11. +* Default to the bundled ``libsodium`` when compiling. +* All raised exceptions are defined mixing-in + ``nacl.exceptions.CryptoError`` + +1.0.1 - 2016-01-24 +------------------ + +* Fix an issue with absolute paths that prevented the creation of wheels. + +1.0 - 2016-01-23 +---------------- + +* PyNaCl has been ported to use the new APIs available in cffi 1.0+. + Due to this change we no longer support PyPy releases older than 2.6. +* Python 3.2 support has been dropped. +* Functions to convert between Ed25519 and Curve25519 keys have been added. + +0.3.0 - 2015-03-04 +------------------ + +* The low-level API (`nacl.c.*`) has been changed to match the + upstream NaCl C/C++ conventions (as well as those of other NaCl bindings). + The order of arguments and return values has changed significantly. To + avoid silent failures, `nacl.c` has been removed, and replaced with + `nacl.bindings` (with the new argument ordering). If you have code which + calls these functions (e.g. `nacl.c.crypto_box_keypair()`), you must review + the new docstrings and update your code/imports to match the new + conventions. + + diff --git

+``Signal`` is a list of registered asynchronous callbacks. + +The signal's life-cycle has two stages: after creation its content +could be filled by using standard list operations: ``sig.append()`` +etc. + +After you call ``sig.freeze()`` the signal is *frozen*: adding, removing +and dropping callbacks is forbidden. + +The only available operation is calling the previously registered +callbacks by using ``await sig.send(data)``. + +For concrete usage examples see the `Signals + +section of the `Web Server Advanced +` chapter of the `aiohttp +documentation`_. + + +Installation +------------ +

+ + attrs + +

+ + +*attrs* is the Python package that will bring back the **joy** of **writing classes** by relieving you from the drudgery of implementing object protocols (aka [dunder methods](https://www.attrs.org/en/latest/glossary.html#term-dunder-methods)). +[Trusted by NASA](https://docs.github.com/en/account-and-profile/setting-up-and-managing-your-github-profile/customizing-your-profile/personalizing-your-profile#list-of-qualifying-repositories-for-mars-2020-helicopter-contributor-achievement) for Mars missions since 2020! + +Its main goal is to help you to write **concise** and **correct** software without slowing down your code. + + +## Sponsors + +*attrs* would not be possible without our [amazing sponsors](https://github.com/sponsors/hynek). +Especially those generously supporting us at the *The Organization* tier and higher: + + + +

+ + + + + + + + + + + +

+ + + +

+ Please consider joining them to help make attrs’s maintenance more sustainable! +

+ + + +## Example + +*attrs* gives you a class decorator and a way to declaratively define the attributes on that class: + + + +```pycon +>>> from attrs import asdict, define, make_class, Factory + +>>> @define +... class SomeClass: +... a_number: int = 42 +... list_of_numbers: list[int] = Factory(list) +... +... def hard_math(self, another_number): +... return self.a_number + sum(self.list_of_numbers) * another_number + + +>>> sc = SomeClass(1, [1, 2, 3]) +>>> sc +SomeClass(a_number=1, list_of_numbers=[1, 2, 3]) + +>>> sc.hard_math(3) +19 +>>> sc == SomeClass(1, [1, 2, 3]) +True +>>> sc != SomeClass(2, [3, 2, 1]) +True + +>>> asdict(sc) +{'a_number': 1, 'list_of_numbers': [1, 2, 3]} + +>>> SomeClass() +SomeClass(a_number=42, list_of_numbers=[]) + +>>> C = make_class("C", ["a", "b"]) +>>> C("foo", "bar") +C(a='foo', b='bar') +``` + +After *declaring* your attributes, *attrs* gives you: + +- a concise and explicit overview of the class's attributes, +- a nice human-readable `__repr__`, +- equality-checking methods, +- an initializer, +- and much more, + +*without* writing dull boilerplate code again and again and *without* runtime performance penalties. + +--- + +This example uses *attrs*'s modern APIs that have been introduced in version 20.1.0, and the *attrs* package import name that has been added in version 21.3.0. +The classic APIs (`@attr.s`, `attr.ib`, plus their serious-business aliases) and the `attr` package import name will remain **indefinitely**. + +Check out [*On The Core API Names*](https://www.attrs.org/en/latest/names.html) for an in-depth explanation! + + +### Hate Type Annotations!? + +No problem! +Types are entirely **optional** with *attrs*. +Simply assign `attrs.field()` to the attributes instead of annotating them with types: + +```python +from attrs import define, field + +@define +class SomeClass: + a_number = field(default=42) + list_of_numbers = field(factory=list) +``` + + +## Data Classes + +On the tin, *attrs* might remind you of `dataclasses` (and indeed, `dataclasses` [are a descendant](https://hynek.me/articles/import-attrs/) of *attrs*). +In practice it does a lot more and is more flexible. +For instance, it allows you to define [special handling of NumPy arrays for equality checks](https://www.attrs.org/en/stable/comparison.html#customization), allows more ways to [plug into the initialization process](https://www.attrs.org/en/stable/init.html#hooking-yourself-into-initialization), has a replacement for `__init_subclass__`, and allows for stepping through the generated methods using a debugger. + +For more details, please refer to our [comparison page](https://www.attrs.org/en/stable/why.html#data-classes), but generally speaking, we are more likely to commit crimes against nature to make things work that one would expect to work, but that are quite complicated in practice. + + +## Project Information + +- [**Changelog**](https://www.attrs.org/en/stable/changelog.html) +-

To adjust +the work factor merely pass the desired number of rounds to +``bcrypt.gensalt(rounds=12)`` which defaults to 12): + +.. code:: pycon + + >>> import bcrypt + >>> password = b"super secret password" + >>> # Hash a password for the first time, with a certain number of rounds + >>> hashed = bcrypt.hashpw(password, bcrypt.gensalt(14)) + >>> # Check that a unhashed password matches one that has previously been + >>> # hashed + >>> if bcrypt.checkpw(password, hashed): + ... print("It Matches!") + ... else: + ... print("It Does not Match :(") + + +Adjustable Prefix +~~~~~~~~~~~~~~~~~ + +Another one of bcrypt's features is an adjustable prefix to let you define what +libraries you'll remain compatible with. To adjust this, pass either ``2a`` or +``2b`` (the default) to ``bcrypt.gensalt(prefix=b"2b")`` as a bytes object. + +As of 3.0.0 the ``$2y$`` prefix is still supported in ``hashpw`` but deprecated. + +Maximum Password Length +~~~~~~~~~~~~~~~~~~~~~~~ + +The bcrypt algorithm only handles passwords up to 72 characters, any characters +beyond that are ignored. To work around this, a common approach is to hash a +password with a cryptographic hash (such as ``sha256``) and then base64 +encode it to prevent NULL byte problems before hashing the result with +``bcrypt``: + +.. code:: pycon + + >>> password = b"an incredibly long password" * 10 + >>> hashed = bcrypt.hashpw( + ... base64.b64encode(hashlib.sha256(password).digest()), + ... bcrypt.gensalt() + ... ) + +Compatibility +------------- + +This library should be compatible with py-bcrypt and it will run on Python +3.8+ (including free-threaded builds), and PyPy 3. + +Security +-------- + +``bcrypt`` follows the `same security policy as cryptography`_, if you +identify a vulnerability, we ask you to contact us privately. + +.. _`same security policy as cryptography`: https://cryptography.io/en/latest/security.html +.. _`standard library`: https://docs.python.org/3/library/hashlib.html#hashlib.scrypt +.. _`argon2_cffi`: https://argon2-cffi.readthedocs.io +.. _`cryptography`: https://cryptography.io/en/latest/hazmat/primitives/key-derivation-functions/#cryptography.hazmat.primitives.kdf.scrypt.Scrypt diff --git a/platform/dataops/dto/.venv/lib/python3.12/site-packages/bcrypt-4.3.0.dist-info/RECORD b/platform/dataops/dto/.venv/lib/python3.12/site-packages/bcrypt-4.3.0.dist-info/RECORD new file mode 100644 index 0000000000000000000000000000000000000000..717568c9a1571282617a1797e11a4dd89d2ca4ed --- /dev/null +++ b/platform/dataops/dto/.venv/lib/python3.12/site-packages/bcrypt-4.3.0.dist-info/RECORD @@ -0,0 +1,11 @@ +bcrypt-4.3.0.dist-info/INSTALLER,sha256=zuuue4knoyJ-UwPPXg8fezS7VCrXJQrAP7zeNuwvFQg,4 +bcrypt-4.3.0.dist-info/LICENSE,sha256=gXPVwptPlW1TJ4HSuG5OMPg-a3h43OGMkZRR1rpwfJA,10850 +bcrypt-4.3.0.dist-info/METADATA,sha256=95qX7ziIfmOF0kNM95YZuWhLVfFy-6EtssVvf1ZgeWg,10042 +bcrypt-4.3.0.dist-info/RECORD,, +bcrypt-4.3.0.dist-info/WHEEL,sha256=XlovOtcAZFqrc4OSNBtc5R3yDeRHyhWP24RdDnylFpY,111 +bcrypt-4.3.0.dist-info/top_level.txt,sha256=BkR_qBzDbSuycMzHWE1vzXrfYecAzUVmQs6G2CukqNI,7 +bcrypt/__init__.py,sha256=cv-NupIX6P7o6A4PK_F0ur6IZoDr3GnvyzFO9k16wKQ,1000 +bcrypt/__init__.pyi,sha256=ITUCB9mPVU8sKUbJQMDUH5YfQXZb1O55F9qvKZR_o8I,333 +bcrypt/__pycache__/__init__.cpython-312.pyc,, +bcrypt/_bcrypt.abi3.so,sha256=oMArVCuY_atg2H4SGNfM-zbfEgUOkd4qSiWn2nPqmXc,644928 +bcrypt/py.typed,sha256=47DEQpj8HBSa-_TImW-5JCeuQeRkm5NMpJWZG3hSuFU,0 diff --git a/platform/dataops/dto/.venv/lib/python3.12/site-packages/bcrypt-4.3.0.dist-info/WHEEL b/platform/dataops/dto/.venv/lib/python3.12/site-packages/bcrypt-4.3.0.dist-info/WHEEL new file mode 100644 index 0000000000000000000000000000000000000000..dd95e91e56353446a5e2171dc18f4a69b79987d4 --- /dev/null +++ b/platform/dataops/dto/.venv/lib/python3.12/site-packages/bcrypt-4.3.0.dist-info/WHEEL @@ -0,0 +1,5 @@ +Wheel-Version: 1.0 +Generator: setuptools (75.8.2) +Root-Is-Purelib: false +Tag: cp39-abi3-manylinux_2_34_x86_64 + diff --git a/platform/dataops/dto/.venv/lib/python3.12/site-packages/bcrypt-4.3.0.dist-info/top_level.txt b/platform/dataops/dto/.venv/lib/python3.12/site-packages/bcrypt-4.3.0.dist-info/top_level.txt new file mode 100644 index 0000000000000000000000000000000000000000..7f0b6e759aaaf6034eb8451960128a353d92c29f --- /dev/null +++ b/platform/dataops/dto/.venv/lib/python3.12/site-packages/bcrypt-4.3.0.dist-info/top_level.txt @@ -0,0 +1 @@ +bcrypt diff --git a/platform/dataops/dto/.venv/lib/python3.12/site-packages/bcrypt/__init__.py b/platform/dataops/dto/.venv/lib/python3.12/site-packages/bcrypt/__init__.py new file mode 100644 index 0000000000000000000000000000000000000000..81a92fd42513254ea6580d66df6006a0a887be21 --- /dev/null +++ b/platform/dataops/dto/.venv/lib/python3.12/site-packages/bcrypt/__init__.py @@ -0,0 +1,43 @@ +# Licensed under the Apache License, Version 2.0 (the "License");

We ensure that we offer the best (reasonable) BC result possible. + +See the docs for advanced usage : [readthedocs.io](https://charset-normalizer.readthedocs.io/en/latest/) + +## 😇 Why + +When I started using Chardet, I noticed that it was not suited to my expectations, and I wanted to propose a +reliable alternative using a completely different method. Also! I never back down on a good challenge! + +I **don't care** about the **originating charset** encoding, because **two different tables** can +produce **two identical rendered string.** +What I want is to get readable text, the best I can. + +In a way, **I'm brute forcing text decoding.** How cool is that ? 😎 + +Don't confuse package **ftfy** with charset-normalizer or chardet. ftfy goal is to repair Unicode string whereas charset-normalizer to convert raw file in unknown encoding to unicode. + +## 🍰 How + + - Discard all charset encoding table that could not fit the binary content. + - Measure noise, or the mess once opened (by chunks) with a corresponding charset encoding. + - Extract matches with the lowest mess detected. + - Additionally, we measure coherence / probe for a language. + +**Wait a minute**, what is noise/mess and coherence according to **YOU ?** + +*Noise :* I opened hundred of text files, **written by humans**, with the wrong encoding table. **I observed**, then +**I established** some ground rules about **what is obvious** when **it seems like** a mess (aka. defining noise in rendered text). + I know that my interpretation of what is noise is probably incomplete, feel free to contribute in order to + improve or rewrite it. + +*Coherence :* For each language there is on earth, we have computed ranked letter appearance occurrences (the best we can). So I thought +that intel is worth something here. So I use those records against decoded text to check if I can detect intelligent design. + +## ⚡ Known limitations + + - Language detection is unreliable when text contains two or more languages sharing identical letters. (eg. HTML (english tags) + Turkish content (Sharing Latin characters)) + - Every charset detector heavily depends on sufficient content. In common cases, do not bother run detection on very tiny content. + +## ⚠️ About Python EOLs + +**If you are running:** + +- Python >=2.7,<3.5: Unsupported +- Python 3.5: charset-normalizer < 2.1 +- Python 3.6: charset-normalizer < 3.1 +- Python 3.7: charset-normalizer < 4.0 + +Upgrade your Python interpreter as soon as possible. + +## 👤 Contributing + +Contributions, issues and feature requests are very much welcome.

Colorama makes this work on +Windows, too, by wrapping ``stdout``, stripping ANSI sequences it finds (which +would appear as gobbledygook in the output), and converting them into the +appropriate win32 calls to modify the state of the terminal. On other platforms, +Colorama does nothing. + +This has the upshot of providing a simple cross-platform API for printing +colored terminal text from Python, and has the happy side-effect that existing +applications or libraries which use ANSI sequences to produce colored output on +Linux or Macs can now also work on Windows, simply by calling +``colorama.just_fix_windows_console()`` (since v0.4.6) or ``colorama.init()`` +(all versions, but may have other side-effects – see below). + +An alternative approach is to install ``ansi.sys`` on Windows machines, which +provides the same behaviour for all applications running in terminals. Colorama +is intended for situations where that isn't easy (e.g., maybe your app doesn't +have an installer.) + +Demo scripts in the source code repository print some colored text using +ANSI sequences. Compare their output under Gnome-terminal's built in ANSI +handling, versus on Windows Command-Prompt using Colorama: + +.. image:: https://github.com/tartley/colorama/raw/master/screenshots/ubuntu-demo.png + :width: 661 + :height: 357 + :alt: ANSI sequences on Ubuntu under gnome-terminal. + +.. image:: https://github.com/tartley/colorama/raw/master/screenshots/windows-demo.png + :width: 668 + :height: 325 + :alt: Same ANSI sequences on Windows, using Colorama. + +These screenshots show that, on Windows, Colorama does not support ANSI 'dim +text'; it looks the same as 'normal text'. + +Usage +----- + +Initialisation +.............. + +If the only thing you want from Colorama is to get ANSI escapes to work on +Windows, then run: + +.. code-block:: python + + from colorama import just_fix_windows_console + just_fix_windows_console() + +If you're on a recent version of Windows 10 or better, and your stdout/stderr +are pointing to a Windows console, then this will flip the magic configuration +switch to enable Windows' built-in ANSI support. + +If you're on an older version of Windows, and your stdout/stderr are pointing to +a Windows console, then this will wrap ``sys.stdout`` and/or ``sys.stderr`` in a +magic file object that intercepts ANSI escape sequences and issues the +appropriate Win32 calls to emulate them. + +In all other circumstances, it does nothing whatsoever. Basically the idea is +that this makes Windows act like Unix with respect to ANSI escape handling. + +It's safe to call this function multiple times. It's safe to call this function +on non-Windows platforms, but it won't do anything. It's safe to call this +function when one or both of your stdout/stderr are redirected to a file – it +won't do anything to those streams. + +Alternatively, you can use the older interface with more features (but also more +potential footguns): + +.. code-block:: python + + from colorama import init + init() + +This does the same thing as ``just_fix_windows_console``, except for the +following differences: + +- It's not safe to call ``init`` multiple times; you can end up with multiple + layers of wrapping and broken ANSI support. + +- Colorama will apply a heuristic to guess whether stdout/stderr support ANSI, + and if it thinks they don't, then it will wrap ``sys.stdout`` and + ``sys.stderr`` in a magic file object that strips out ANSI escape sequences + before printing them. This happens on all platforms, and can be convenient if + you want to write your code to emit ANSI escape sequences unconditionally, and + let Colorama decide whether they should actually be output. But note that + Colorama's heuristic is not particularly clever. + +- ``init`` also accepts explicit keyword args to enable/disable various + functionality – see below. + +To stop using Colorama before your program exits, simply call ``deinit()``. +This will restore ``stdout`` and ``stderr`` to their original values, so that +Colorama is disabled. To resume using Colorama again, call ``reinit()``; it is +cheaper than calling ``init()`` again (but does the same thing). + +Most users should depend on ``colorama >= 0.4.6``, and use +``just_fix_windows_console``. The old ``init`` interface will be supported +indefinitely for backwards compatibility, but we don't plan to fix any issues +with it, also for backwards compatibility. + +Colored Output +.............. + +Cross-platform printing of colored text can then be done using Colorama's +constant shorthand for ANSI escape sequences. These are deliberately +rudimentary, see below. + +.. code-block:: python + + from colorama import Fore, Back, Style + print(Fore.RED + 'some red text') + print(Back.GREEN + 'and with a green background') + print(Style.DIM + 'and in dim text') + print(Style.RESET_ALL) + print('back to normal now') + +...or simply by manually printing ANSI sequences from your own code: + +.. code-block:: python + + print('\033[31m' + 'some red text') + print('\033[39m') # and reset to default color + +...or, Colorama can be used in conjunction with existing ANSI libraries +such as the venerable `Termcolor `_ +the fabulous `Blessings `_, +or the incredible `_Rich `_. + +If you wish Colorama's Fore, Back and Style constants were more capable, +then consider using one of the above highly capable libraries to generate +colors, etc, and use Colorama just for its primary purpose: to convert +those ANSI sequences to also work on Windows: + +SIMILARLY, do not send PRs adding the generation of new ANSI types to Colorama. +We are only interested in converting ANSI codes to win32 API calls, not +shortcuts like the above to generate ANSI characters. + +.. code-block:: python + + from colorama import just_fix_windows_console + from termcolor import colored + + # use Colorama to make Termcolor work on Windows too + just_fix_windows_console() + + # then use Termcolor for all colored text output + print(colored('Hello, World!', 'green', 'on_red')) + +Available formatting constants are:: + + Fore: BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE, RESET. + Back: BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE, RESET. + Style: DIM, NORMAL, BRIGHT, RESET_ALL + +``Style.RESET_ALL`` resets foreground, background, and brightness. Colorama will +perform this reset automatically on program exit. + +These are fairly well supported, but not part of the standard:: + + Fore: LIGHTBLACK_EX, LIGHTRED_EX, LIGHTGREEN_EX, LIGHTYELLOW_EX, LIGHTBLUE_EX, LIGHTMAGENTA_EX, LIGHTCYAN_EX, LIGHTWHITE_EX + Back: LIGHTBLACK_EX, LIGHTRED_EX, LIGHTGREEN_EX, LIGHTYELLOW_EX, LIGHTBLUE_EX, LIGHTMAGENTA_EX, LIGHTCYAN_EX, LIGHTWHITE_EX + +Cursor Positioning +.................. + +ANSI codes to reposition the cursor are supported. See ``demos/demo06.py`` for +an example of how to generate them. + +Init Keyword Args +................. + +``init()`` accepts some ``**kwargs`` to override default behaviour. + +init(autoreset=False): + If you find yourself repeatedly sending reset sequences to turn off color + changes at the end of every print, then ``init(autoreset=True)`` will + automate that: + + .. code-block:: python + + from colorama import init + init(autoreset=True) + print(Fore.RED + 'some red text') + print('automatically back to default color again') + +init(strip=None): + Pass ``True`` or ``False`` to override whether ANSI codes should be + stripped from the output. The default behaviour is to strip if on Windows + or if output is redirected (not a tty). + +init(convert=None): + Pass ``True`` or ``False`` to override whether to convert ANSI codes in the + output into win32 calls. The default behaviour is to convert if on Windows + and output is to a tty (terminal). + +init(wrap=True): + On Windows, Colorama works by replacing ``sys.stdout`` and ``sys.stderr`` + with proxy objects, which override the ``.write()`` method to do their work. + If this wrapping causes you problems, then this can be disabled by passing + ``init(wrap=False)``. The default behaviour is to wrap if ``autoreset`` or + ``strip`` or ``convert`` are True. + + When wrapping is disabled, colored printing on non-Windows platforms will + continue to work as normal. To do cross-platform colored output, you can + use Colorama's ``AnsiToWin32`` proxy directly: + + .. code-block:: python + + import sys + from colorama import init, AnsiToWin32 + init(wrap=False) + stream = AnsiToWin32(sys.stderr).stream + + # Python 2 + print >>stream, Fore.BLUE + 'blue text on stderr' + + # Python 3 + print(Fore.BLUE + 'blue text on stderr', file=stream) + +Recognised ANSI Sequences +......................... + +ANSI sequences generally take the form:: + + ESC [ ; ... + +Where ```` is an integer, and ```` is a single letter. Zero or +more params are passed to a ````. If no params are passed, it is +generally synonymous with passing a single zero. No spaces exist in the +sequence; they have been inserted here simply to read more easily. + +The only ANSI sequences that Colorama converts into win32 calls are:: + + ESC [ 0 m # reset all (colors and brightness) + ESC [ 1 m # bright + ESC [ 2 m # dim (looks same as normal brightness) + ESC [ 22 m # normal brightness + + # FOREGROUND: + ESC [ 30 m # black + ESC [ 31 m # red + ESC [ 32 m # green + ESC [ 33 m # yellow + ESC [ 34 m # blue + ESC [ 35 m # magenta + ESC [ 36 m # cyan + ESC [ 37 m # white + ESC [ 39 m # reset + + # BACKGROUND + ESC [ 40 m # black + ESC [ 41 m # red + ESC [ 42 m # green + ESC [ 43 m # yellow + ESC [ 44 m # blue + ESC [ 45 m # magenta + ESC [ 46 m # cyan + ESC [ 47 m # white + ESC [ 49 m # reset + + # cursor positioning + ESC [ y;x H # position cursor at x across, y down + ESC [ y;x f # position cursor at x across, y down + ESC [ n A # move cursor n lines up + ESC [ n B # move cursor n lines down + ESC [ n C # move cursor n characters forward + ESC [ n D # move cursor n characters backward + + # clear the screen + ESC [ mode J # clear the screen + + # clear the line + ESC [ mode K # clear the line + +Multiple numeric params to the ``'m'`` command can be combined into a single +sequence:: + + ESC [ 36 ; 45 ; 1 m # bright cyan text on magenta background + +All other ANSI sequences of the form ``ESC [ ; ... `` +are silently stripped from the output on Windows. + +Any other form of ANSI sequence, such as single-character codes or alternative +initial characters, are not recognised or stripped. It would be cool to add +them though. Let me know if it would be useful for you, via the Issues on +GitHub. + +Status & Known Problems +----------------------- + +I've personally only tested it on Windows XP (CMD, Console2), Ubuntu +(gnome-terminal, xterm), and OS X. + +Some valid ANSI sequences aren't recognised. + +If you're hacking on the code, see `README-hacking.md`_. ESPECIALLY, see the +explanation there of why we do not want PRs that allow Colorama to generate new +types of ANSI codes. + +See outstanding issues and wish-list: +https://github.com/tartley/colorama/issues + +If anything doesn't work for you, or doesn't do what you expected or hoped for, +I'd love to hear about it on that issues list, would be delighted by patches, +and would be happy to grant commit access to anyone who submits a working patch +or two. + +.. _README-hacking.md: README-hacking.md + +License +------- + +Copyright Jonathan Hartley & Arnon Yaari, 2013-2020.

+[![Docs](https://readthedocs.org/projects/filesystem-spec/badge/?version=latest)](https://filesystem-spec.readthedocs.io/en/latest/?badge=latest) + +A specification for pythonic filesystems. + +## Install + +```bash +pip install fsspec +``` + +would install the base fsspec. Various optionally supported features might require specification of custom +extra require, e.g. `pip install fsspec[ssh]` will install dependencies for `ssh` backends support. +Use `pip install fsspec[full]` for installation of all known extra dependencies. + +Up-to-date package also provided through conda-forge distribution: + +```bash +conda install -c conda-forge fsspec +``` + + +## Purpose + +To produce a template or specification for a file-system interface, that specific implementations should follow, +so that applications making use of them can rely on a common behaviour and not have to worry about the specific +internal implementation decisions with any given backend. Many such implementations are included in this package, +or in sister projects such as `s3fs` and `gcsfs`. + +In addition, if this is well-designed, then additional functionality, such as a key-value store or FUSE +mounting of the file-system implementation may be available for all implementations "for free". + +## Documentation + +Please refer to [RTD](https://filesystem-spec.readthedocs.io/en/latest/?badge=latest) + +## Develop + +fsspec uses GitHub Actions for CI. Environment files can be found +in the "ci/" directory. Note that the main environment is called "py38", +but it is expected that the version of python installed be adjustable at +CI runtime. For local use, pick a version suitable for you. + +```bash +# For a new environment (mamba / conda). +mamba create -n fsspec -c conda-forge python=3.9 -y +conda activate fsspec + +# Standard dev install with docs and tests. +pip install -e ".[dev,doc,test]" + +# Full tests except for downstream +pip install s3fs +pip uninstall s3fs +pip install -e .[dev,doc,test_full] +pip install s3fs --no-deps +pytest -v + +# Downstream tests. +sh install_s3fs.sh +# Windows powershell. +install_s3fs.sh +``` + +### Testing + +Tests can be run in the dev environment, if activated, via ``pytest fsspec``. + +The full fsspec suite requires a system-level docker, docker-compose, and fuse +installation. If only making changes to one backend implementation, it is +not generally necessary to run all tests locally. + +It is expected that contributors ensure that any change to fsspec does not +cause issues or regressions for either other fsspec-related packages such +as gcsfs and s3fs, nor for downstream users of fsspec. The "downstream" CI +run and corresponding environment file run a set of tests from the dask +test suite, and very minimal tests against pandas and zarr from the +test_downstream.py module in this repo. + +### Code Formatting + +fsspec uses [Black](https://black.readthedocs.io/en/stable) to ensure +a consistent code format throughout the project. +Run ``black fsspec`` from the root of the filesystem_spec repository to +auto-format your code. Additionally, many editors have plugins that will apply +``black`` as you edit files. ``black`` is included in the ``tox`` environments. + +Optionally, you may wish to setup [pre-commit hooks](https://pre-commit.com) to +automatically run ``black`` when you make a git commit. +Run ``pre-commit install --install-hooks`` from the root of the +filesystem_spec repository to setup pre-commit hooks. ``black`` will now be run +before you commit, reformatting any changed files. You can format without +committing via ``pre-commit run`` or skip these checks with ``git commit +--no-verify``. + +## Support + +Work on this repository is supported in part by: + +"Anaconda, Inc. -

Depending on GEOS +requires any data conversion bug fixes to happen upstream, which takes time +and effort. Ultimately, this was the inspiration to create a more +lightweight, pure-Python conversion library as an alterntive tool for +reliably converting data between various geospatial formats. + +The name "GeoMet" was inspired by "met", the German word for +[mead](http://en.wikipedia.org/wiki/Mead). It is also a shortened version of +the word "geometry". + +## Limitations + +### Outputing "empty" geometries to binary formats is not supported + +Attempting to output an empty geometry to a binary format will result in an exception: `ValueError: Empty geometries cannot be represented in WKB. Reason: The dimensionality of the WKB would be ambiguous.` There are a few reasons for this this limitation: +- Any `EMTPY` geometry (e.g., `POINT EMPTY`, `MULTIPOLYGON EMPTY`, etc.) cannot be converted into binary format because binary formats such as WKB require an explicit dimension type (2d, Z, M, or ZM). This means that some objects cannot be reliably converted to and from different formats in a [bijective](https://en.wikipedia.org/wiki/Bijection) manner. +- The [GeoJSON standard](https://www.rfc-editor.org/rfc/rfc7946) does have a way of representing empty geometries; however, details are minimal and the dimensionality of such an object remains ambiguous. +- Representing some geometry types (such as points and lines) as "empty" is [deeply flawed to begin with](http://aleph0.clarku.edu/~djoyce/elements/bookI/defI1.html). For example, a point can represent any location in 2d, 3d, or 4d space. However, a point is infinitesimally small (it has no size) and it can't contain anything (it can't be "full"), therefore, it doesn't make sense for a point to be "empty". + +As a result, GeoMet has chosen to not attempt to address these problems, and +simply raise an exception instead. + +Example: + + >>> import geomet + >>> import geomet.wkt as wkt + >>> import geomet.wkb as wkb + >>> pt = wkt.loads('POINT EMPTY') + >>> pt + {'type': 'Point', 'coordinates': []} + >>> wkb.dumps(pt) + Traceback (most recent call last): + File "", line 1, in + File "/home/jdoe/geomet/geomet/wkb.py", line 216, in dumps + return _dumps(obj, big_endian) + File "/home/jdoe/geomet/geomet/wkb.py", line 238, in _dumps + raise ValueError( + ValueError: Empty geometries cannot be represented in WKB.

This is the latest version of +the protocol and is sometimes referred to as “IDNA 2008”. + +This library also provides support for Unicode Technical +Standard 46, `Unicode IDNA Compatibility Processing +`_. + +This acts as a suitable replacement for the “encodings.idna” +module that comes with the Python standard library, but which +only supports the older superseded IDNA specification (`RFC 3490 +`_). + +Basic functions are simply executed: + +.. code-block:: pycon + + >>> import idna + >>> idna.encode('ドメイン.テスト') + b'xn--eckwd4c7c.xn--zckzah' + >>> print(idna.decode('xn--eckwd4c7c.xn--zckzah')) + ドメイン.テスト + + +Installation +------------ + +This package is available for installation from PyPI: + +.. code-block:: bash + + $ python3 -m pip install idna + + +Usage +----- + +For typical usage, the ``encode`` and ``decode`` functions will take a +domain name argument and perform a conversion to A-labels or U-labels +respectively. + +.. code-block:: pycon + + >>> import idna + >>> idna.encode('ドメイン.テスト') + b'xn--eckwd4c7c.xn--zckzah' + >>> print(idna.decode('xn--eckwd4c7c.xn--zckzah')) + ドメイン.テスト + +You may use the codec encoding and decoding methods using the +``idna.codec`` module: + +.. code-block:: pycon + + >>> import idna.codec + >>> print('домен.испытание'.encode('idna2008')) + b'xn--d1acufc.xn--80akhbyknj4f' + >>> print(b'xn--d1acufc.xn--80akhbyknj4f'.decode('idna2008')) + домен.испытание + +Conversions can be applied at a per-label basis using the ``ulabel`` or +``alabel`` functions if necessary: + +.. code-block:: pycon + + >>> idna.alabel('测试') + b'xn--0zwm56d' + +Compatibility Mapping (UTS #46) ++++++++++++++++++++++++++++++++ + +As described in `RFC 5895 `_, the +IDNA specification does not normalize input from different potential +ways a user may input a domain name. This functionality, known as +a “mapping”, is considered by the specification to be a local +user-interface issue distinct from IDNA conversion functionality. + +This library provides one such mapping that was developed by the +Unicode Consortium. Known as `Unicode IDNA Compatibility Processing +`_, it provides for both a regular +mapping for typical applications, as well as a transitional mapping to +help migrate from older IDNA 2003 applications. Strings are +preprocessed according to Section 4.4 “Preprocessing for IDNA2008” +prior to the IDNA operations. + +For example, “Königsgäßchen” is not a permissible label as *LATIN +CAPITAL LETTER K* is not allowed (nor are capital letters in general). +UTS 46 will convert this into lower case prior to applying the IDNA +conversion. + +.. code-block:: pycon + + >>> import idna + >>> idna.encode('Königsgäßchen') + ... + idna.core.InvalidCodepoint: Codepoint U+004B at position 1 of 'Königsgäßchen' not allowed + >>> idna.encode('Königsgäßchen', uts46=True) + b'xn--knigsgchen-b4a3dun' + >>> print(idna.decode('xn--knigsgchen-b4a3dun')) + königsgäßchen + +Transitional processing provides conversions to help transition from +the older 2003 standard to the current standard. For example, in the +original IDNA specification, the *LATIN SMALL LETTER SHARP S* (ß) was +converted into two *LATIN SMALL LETTER S* (ss), whereas in the current +IDNA specification this conversion is not performed. + +.. code-block:: pycon + + >>> idna.encode('Königsgäßchen', uts46=True, transitional=True) + 'xn--knigsgsschen-lcb0w' + +Implementers should use transitional processing with caution, only in +rare cases where conversion from legacy labels to current labels must be +performed (i.e. IDNA implementations that pre-date 2008). For typical +applications that just need to convert labels, transitional processing +is unlikely to be beneficial and could produce unexpected incompatible +results. + +``encodings.idna`` Compatibility +++++++++++++++++++++++++++++++++ + +Function calls from the Python built-in ``encodings.idna`` module are +mapped to their IDNA 2008 equivalents using the ``idna.compat`` module. +Simply substitute the ``import`` clause in your code to refer to the new +module name. + +Exceptions +---------- + +All errors raised during the conversion following the specification +should raise an exception derived from the ``idna.IDNAError`` base +class. + +More specific exceptions that may be generated as ``idna.IDNABidiError`` +when the error reflects an illegal combination of left-to-right and +right-to-left characters in a label; ``idna.InvalidCodepoint`` when +a specific codepoint is an illegal character in an IDN label (i.e. +INVALID); and ``idna.InvalidCodepointContext`` when the codepoint is +illegal based on its positional context (i.e. it is CONTEXTO or CONTEXTJ +but the contextual requirements are not satisfied.) + +Building and Diagnostics +------------------------ + +The IDNA and UTS 46 functionality relies upon pre-calculated lookup +tables for performance. These tables are derived from computing against +eligibility criteria in the respective standards. These tables are +computed using the command-line script ``tools/idna-data``. + +This tool will fetch relevant codepoint data from the Unicode repository +and perform the required calculations to identify eligibility. There are +three main modes: + +* ``idna-data make-libdata``. Generates ``idnadata.py`` and + ``uts46data.py``, the pre-calculated lookup tables used for IDNA and + UTS 46 conversions. Implementers who wish to track this library against + a different Unicode version may use this tool to manually generate a + different version of the ``idnadata.py`` and ``uts46data.py`` files. + +* ``idna-data make-table``. Generate a table of the IDNA disposition + (e.g. PVALID, CONTEXTJ, CONTEXTO) in the format found in Appendix + B.1 of RFC 5892 and the pre-computed tables published by `IANA + `_. + +* ``idna-data U+0061``. Prints debugging output on the various + properties associated with an individual Unicode codepoint (in this + case, U+0061), that are used to assess the IDNA and UTS 46 status of a + codepoint. This is helpful in debugging or analysis. + +The tool accepts a number of arguments, described using ``idna-data +-h``. Most notably, the ``--version`` argument allows the specification +of the version of Unicode to be used in computing the table data. For +example, ``idna-data --version 9.0.0 make-libdata`` will generate +library data against Unicode 9.0.0. + + +Additional Notes +---------------- + +* **Packages**. The latest tagged release version is published in the + `Python Package Index `_. + +* **Version support**. This library supports Python 3.6 and higher. + As this library serves as a low-level toolkit for a variety of + applications, many of which strive for broad compatibility with older + Python versions, there is no rush to remove older interpreter support. + Removing support for older versions should be well justified in that the + maintenance burden has become too high. + +* **Python 2**. Python 2 is supported by version 2.x of this library. + Use "idna<3" in your requirements file if you need this library for + a Python 2 application. Be advised that these versions are no longer + actively developed. + +* **Testing**. The library has a test suite based on each rule of the + IDNA specification, as well as tests that are provided as part of the + Unicode Technical Standard 46, `Unicode IDNA Compatibility Processing + `_. + +* **Emoji**. It is an occasional request to support emoji domains in + this library. Encoding of symbols like emoji is expressly prohibited by + the technical standard IDNA 2008 and emoji domains are broadly phased + out across the domain industry due to associated security risks. For + now, applications that need to support these non-compliant labels + may wish to consider trying the encode/decode operation in this library + first, and then falling back to using `encodings.idna`. See `the Github + project `_ for more discussion. + diff --git a/platform/dataops/dto/.venv/lib/python3.12/site-packages/idna-3.10.dist-info/RECORD

parser module +having a unique set of features: + +* maintains order of sections and entries +* supports multi-line values with or without line-continuations +* supports "#" comments everywhere +* raises errors with proper line-numbers +* no bells and whistles like automatic substitutions +* iniconfig raises an Error if two sections have the same name. + +If you encounter issues or have feature wishes please report them to: + + https://github.com/RonnyPfannschmidt/iniconfig/issues + +Basic Example +=================================== + +If you have an ini file like this: + +.. code-block:: ini + + # content of example.ini + [section1] # comment + name1=value1 # comment + name1b=value1,value2 # comment + + [section2] + name2= + line1 + line2 + +then you can do: + +.. code-block:: pycon + + >>> import iniconfig + >>> ini = iniconfig.IniConfig("example.ini") + >>> ini['section1']['name1'] # raises KeyError if not exists + 'value1' + >>> ini.get('section1', 'name1b', [], lambda x: x.split(",")) + ['value1', 'value2'] + >>> ini.get('section1', 'notexist', [], lambda x: x.split(",")) + [] + >>> [x.name for x in list(ini)] + ['section1', 'section2'] + >>> list(list(ini)[0].items()) + [('name1', 'value1'), ('name1b', 'value1,value2')] + >>> 'section1' in ini + True + >>> 'inexistendsection' in ini + False diff --git

Special +placeholders in the template allow writing code similar to Python +syntax. Then the template is passed data to render the final document. + +It includes: + +- Template inheritance and inclusion. +- Define and import macros within templates. +- HTML templates can use autoescaping to prevent XSS from untrusted + user input. +- A sandboxed environment can safely render untrusted templates. +- AsyncIO support for generating templates and calling async + functions. +- I18N support with Babel. +- Templates are compiled to optimized Python code just-in-time and + cached, or can be compiled ahead-of-time. +- Exceptions point to the correct line in templates to make debugging + easier. +- Extensible filters, tests, functions, and even syntax. + +Jinja's philosophy is that while application logic belongs in Python if +possible, it shouldn't make the template designer's job difficult by +restricting functionality too much. + + +## In A Nutshell + +```jinja +{% extends "base.html" %} +{% block title %}Members{% endblock %} +{% block content %} + +{% endblock %} +``` + +## Donate + +The Pallets organization develops and supports Jinja and other popular +packages.
