[issue39539] Improve Keccak support in hashlib including KangarooTwelve
New submission from Gilles Van Assche : Dear all, I think it would be nice if hashlib would include the support of Keccak with a chosen suffix, as well as the fast instance KangarooTwelve (K12). 1) Currently, hashlib's interface for Keccak only supports the 6 instances of FIPS 202 (SHA3-* and SHAKE*). However, the instances in NIST SP 800-185 (cSHAKE, KMAC, …) use a different suffix and therefore cannot be instantiated on top of the aforementioned 6 instances. Instead, simply adding the suffix as an argument to the constructor would enable a user to instantiate plain Keccak (as in Ethereum) or the SP 800-185 instances. 2) K12 is an alternative hash function (and XOF) in the Keccak family. It is fast, parallelizable and it benefits directly from the cryptanalysis on the (unchanged) underlying permutation since 2008. This would be IMHO a valuable addition to hashlib. Among others, implementations of K12 can be found in the XKCP on GitHub. Kind regards, Gilles (co-designer of Keccak and K12) -- components: Library (Lib) messages: 361280 nosy: gvanas priority: normal severity: normal status: open title: Improve Keccak support in hashlib including KangarooTwelve type: enhancement versions: Python 3.9 ___ Python tracker <https://bugs.python.org/issue39539> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Thanks Mark,
multipart is close to what I need and will give me some inpiration.
Unfortunately, it works for multipart/form-data server-side handling, when I'm
searching for a multipart/mixed client side handling of a response. In
addition, it does not yield the headers specific to each data chunk from the
response, and I need those headers.
To be more specific, I'm buiding with the excellent requests lib and Python
2.7 (sorry, I can't go to Python 3.x at the moment) a client library for the
documents database MarkLogic 8 that provides some APIs with multipart/mixed
responses like this one:
http://docs.marklogic.com/REST/POST/v1/eval
In other words I need something that may be used like this :
response = requests.post(some_uri, params=some_params, stream=True)
if response.headers['content-type'].startswith('multipart/mixed'):
boundary = parse_boundary(response.headers['content-type'])
generator = iter_multipart_response(response, boundary)
for part_headers, part_body in generator:
# I'm consuming parsed headers and bodies from response
# In my application code

Stopping a wsgiref server programmatically
Hi, I made a small / minimal wsgiref HTTP server dedicated to unittest stubs (testing custom REST client and other likes) that works pretty good in a separate thread. https://gist.github.com/glenfant/7369894 Feel free to reuse it in your own unittest stubs/mocks. But it only works like a charm in an Unix box, due to the use of a control pipe ( https://gist.github.com/glenfant/7369894#file-pipetestserver-py-L118 ) that's checked with select.select ( https://gist.github.com/glenfant/7369894#file-pipetestserver-py-L133 ) and can be stopped on request when writing in that pipe ( https://gist.github.com/glenfant/7369894#file-pipetestserver-py-L173 ).

=
Internal Server Error: The server encountered an internal error or

Iterating over files of a huge directory
Hi, I have googled but did not find an efficient solution to my problem. My customer provides a directory with a hge list of files (flat, potentially 10+) and I cannot reasonably use os.listdir(this_path) unless creating a big memory footprint. So I'm looking for an iterator that yields the file names of a directory and does not make a giant list of what's in. i.e : for filename in enumerate_files(some_directory): # My cooking...

Question about long-running web scripts
Hello I'd like to check something about running Python web applications. Generally speaking, the reason scripts run faster when called through FastCGI or the mod_* modules, is because the interpreter is already up and running.

OTOH, Python web scripts can be written as long-running scripts: In this case, what is the added-value of using FastCGI?

I need to get the big picture about the different solutions to run a Python web application. From what I read, it seems like this is the way things involved over the years: CGI : original method. Slow because the server has to spawn a new process to run the interpreter + script every time a script is run. mod_python : Apache module alternative to CGI. The interpreter is loaded once, and running a script means just handling the script mod_wsgi : mod_python is no longer developped, and mod_wsgi is its new reincarnation FastCGI and SCGI: Faster alternativees to CGI; Run as independent programs, and communicate with the web server through either a Unix socket (located on the same host) or a TCP socket (remote host) Is this correct?

Running Python web apps on shared ASO servers?
Hello I use A Small Orange (ASO) as my web provider. Asking the question in their forum so far didn't work, so I figured I might have a faster answer by asking here. Support replied this in an old thread: Just a CGI option. We don't have enough users to justify adding mod_python support. http://forums.asmallorange.com/topic/4672-python-support/page__hl__python http://forums.asmallorange.com/topic/4918-python-fcgi-verses-mod-python/ Does it mean that ASO only supports writing Python web apps as long-running processes (CGI, FCGI, WSGI, SCGI) instead of embedded Python à la PHP? If that's the case, which smallest tool would you recomment to write basic apps, eg. handling forms, etc.? Thank you. -- http://mail.python.org/mailman/listinfo/python-list

Using a CMS for small site?
Hello Someone I know with no computer knowledge has a studio appartment to rent in Paris and spent four months building a small site in Joomla to find short-time renters. The site is just... - a few web pages that include text (in four languages) and pictures displayed in a Flash slide show - a calendar to show availability - a form to send e-mail with anti-SPAM support - (ASAP) online payment Out of curiosity, are there CMS/frameworks in Python that can do this? Django? Other? Is a full-fledged CMS even needed for something like that? Thank you. -- http://mail.python.org/mailman/listinfo/python-list

It's the non-magic way of doing things. Also, it plays very nicely with the MUD style of process, which is something I do a lot with Pike. Plus, if you manage it right, you have a guarantee that you can never be in a half-updated state - that's somewhat tricky when you have inter-dependencies in PHP code and the file system itself manages things. What happens if a request comes in while you're half-way through uploading new code to the server? By default, you could use half old code and half new code. Keeping everything in memory makes it easier to prevent that. Thanks for the input. -- http://mail.python.org/mailman/listinfo/python-list

I have a couple more questions: 1. Today what is the recommended way to connect a long-running Python web application with a web server running in the front? FastCGI? WSGI? Other? 2. Which solid web server is recommended to connect to Python web applications in the back? 3.
