What is it about Python that makes developers love fragmentation so much? Sending HTTP requests is a basic capability in the modern world, the standard library should include a friendly, fully-featured, battle-tested, async-ready client. But not in Python, stdlib only has the ugly urllib.request, and everyone is using third party stuff like requests or httpx, which aren't always well maintained. (See also: packaging)
You would think that sending HTTP requests is a basic capability, but I've had fun in many languages doing so. Long ago (2020, or not so long ago, depending on how you look at it) I was surprised that doing an HTTP request on node using no dependencies was a little awkward:
const response = await new Promise( (resolve, reject) => {
const req = https.request(url, {
}, res => {
let body = "";
res.on("data", data => {
body += data;
});
res.on('end', () => {
resolve(body);
});
});
req.end();
});
Yes, thankfully! It's amusing to read what they say about fetch on nodejs.org [1]:
> Undici is an HTTP client library that powers the fetch API in Node.js. It was written from scratch and does not rely on the built-in HTTP client in Node.js. It includes a number of features that make it a good choice for high-performance applications.
Note that node-fetch will silently ignore any overrides to "forbidden" request headers like Host, since it's designed for parity with fetch behavior in the browser. This caused a minor debugging headache for me once.
Web standards have rich support for incremental/chunked payloads, the original node APIs are designed around it. From this lens the Node APIs make sense.
AFAICT, lacking a (good) standard HTTP library is kind of the norm in popular languages. Python, Ruby, Rust, etc. all either have a lackluster standard one or are missing one. I think it sits between two many decision pressures for most languages: there are a _lot_ of different RFCs both required and implied, lots of different idioms you could pick for making requests, lots of different places to draw the line on what to support, etc.
The notable exception is Go, which has a fantastic one. But Go is pretty notable for having an incredible standard library in general.
> Sending HTTP requests is a basic capability in the modern world, the standard library should include a friendly, fully-featured, battle-tested, async-ready client.
I've noticed that many languages struggle with HTTP in the standard library, even if the rest of the stdlib is great. I think it's just difficult to strike the right balance between "easy to use" and "covers every use case", with most erring (justifiably) toward the latter.
HTTP client is at the intersection of "necessary software building block" and "RFC 2616 intricacies that are hard to implement". Has nothing to do with Python really.
> Then I found out it was broken. I contributed a fix. The fix was ignored and there was never any release since November 2024.
This seems like a pretty good reason to fork to me.
> Sending HTTP requests is a basic capability in the modern world, the standard library should include a friendly, fully-featured, battle-tested, async-ready client. But not in Python,
Or Javascript (well node), or golang (http/net is _worse_ than urllib IMO), Rust , Java (UrlRequest is the same as python's), even dotnet's HttpClient is... fine.
Honestly the thing that consistently surprises me is that requests hasn't been standardised and brought into the standard library
For the record, you're most likely not even interacting with that API directly if you're using any current framework, because most just provide automagically generated clients and you only define the interface with some annotations
Your http client setup is over-complicated. You certainly don't need `.proxy` if you are not using a proxy or if you are using the system default proxy, nor do you need `.authenticator` if you are not doing HTTP authentication. Nor do you need `version` since there is already a fallback to HTTP/1.1.
To me what makes this very "Java" is the arguments being passed, and all the OOP stuff that isn't providing any benefit and isn't really modeling real-world-ish objects (which IMHO is where OOP shines). .version(Version.HTTP_1_1) and .followRedirects(Redirect.NORMAL) I can sort of accept, but it requires knowing what class and value to pass, which is lookups/documentation reference. These are spread out over a bunch of classes. But we start getting so "Java" with the next ones. .connectTimeout(Duration.ofSeconds(20)) (why can't I just pass 20 or 20_000 or something? Do we really need another class and method here?) .proxy(ProxySelector.of(new InetSocketAddress("proxy.example.com", 80))), geez that's complex. .authenticator(Authenticator.getDefault()), why not just pass bearer token or something? Now I have to look up this Authenticator class, initialize it, figure out where it's getting the credentials, how it's inserting them, how I put the credentials in the right place, etc. The important details are hidden/obscured behind needless abstraction layers IMHO.
I think Java is a good language, but most modern Java patterns can get ludicrous with the abstractions. When I was writing lots of Java, I was constantly setting up an ncat listener to hit so I could see what it's actually writing, and then have to hunt down where a certain thing is being done and figuring out the right way to get it to behave correctly. Contrast with a typical Typescript HTTP request and you can mostly tell just from reading the snippet what the actual HTTP request is going to look like.
> but it requires knowing what class and value to pass
Unless you use a text editor without any coding capabilities, your IDE should show you which values you can pass. The alternative is to have more methods, I guess?
> why can't I just pass 20 or 20_000 or something
20 what? Milliseconds? Seconds? Minutes? While I wouldn't write the full Duration.ofSeconds(20) (you can save the "Duration."), I don't understand how one could prefer a version that makes you guess the unit.
Yes it is, can't add anything here. There's a tradeoff between "do the simple thing" and "make all things possible", and Java chooses the second here.
> .authenticator(Authenticator.getDefault()), why not just pass bearer token or something?
Because this Authenticator is meant for prompting a user interactively. I concur that this is very confusing, but if you want a Bearer token, just set the header.
Yeah this is all over Rust codebases too for good reason. The argument is that default params obfuscate behaviour and passing in a struct (in Rust) with defaults kneecaps your ability to validate parameters at compile time.
Thr comment I replied to was talking about sending a http requests. Go’s server side net/http is excellent, the client side is clunky verbose and suffers from many of the problems that Python’s urllib does.
>The Requests package is recommended for a higher-level HTTP client interface.
Which was fine when requests were the de-facto-standard only player in town, but at some point modern problems (async, http2) required modern solutions (httpx) and thus ecosystem fragmentation began.
Well, the reason for all the fragmentation is because the Python stdlib doesn't have the core building blocks for an async http or http2 client in the way requests could build on urllib.
The h11, h2, httpcore stack is probably the closest thing to what the Python stdlib should look like to end the fragmentation but it would be a huge undertaking for the core devs.
It's fine but it's sharp-edged, in that it's recommended to use IHttpClientFactory to avoid the dual problem of socket exhaustion ( if creating/destroying lots of HttpClients ) versus DNS caching outliving DNS ( if using a very long-lived singleton HttpClient ).
And while this article [1] says "It's been around for a while", it was only added in .NET Framework 4.5, which shows it took a while for the API to stabilise. There were other ways to make web requests before that of course, and also part of the standard library, and it's never been "difficult" to do so, but there is a history prior to HttpClient of changing ways to do requests.
For modern dotnet however it's all pretty much a solved problem, and there's only ever been HttpClient and a fairly consistent story of how to use it.
httpx has async support (much like aiohttp), whereas urllib is blocking-only. If you need to make N concurrent requests, urllib requires N threads or processes.
Everybody's got a different idea of what it means for a library to be "friendly" and "fully-featured" though. It's probably better to keep the standard library as minimal as possible in order to avoid enshrining bad software. Programming languages could have curated "standard distributions" instead that include all the commonly used "best practice" libraries at the time.
That situation should be avoided. People should have to create their own libraries until everyone empirically converges into a de facto standard that can then be made official.
I realized this the other day, and dub it Bram's Law -- Bram
Bram's Law
The easier a piece of software is to write, the worse it's implemented in practice. Why? Easy software projects can be done by almost any random person, so they are. It's possible to try to nudge your way into being the standard for an easy thing based on technical merit, but that's rather like trying to become a hollywood star based on talent and hard work. You're much better off trading it all in for a good dose of luck.
This is why HTTP is a mess while transaction engines are rock solid. Almost any programmer can do a mediocre but workable job of extending HTTP, (and boy, have they,) but most people can't write a transaction engine which even functions. The result is that very few transaction engines are written, almost all of them by very good programmers, and the few which aren't up to par tend to be really bad and hardly get used. HTTP, on the other hand, has all kinds of random people hacking on it, as a result of which Python has a 'fully http 1.1 compliant http library which raises assertion failures during normal operation.
Remember this next time you're cursing some ubiquitous but awful third party library and thinking of writing a replacement. With enough coal, even a large diamond is unlikely to be the first thing picked up. Save your efforts for more difficult problems where you can make a difference. The simple problems will continue to be dealt with incompetently. It sucks, but we'll waste a lot less time if we learn to accept this fact.
The HTTP protocol is easy to implement the basic features but hard to implement a full version that is also efficient.
I've often ended up reimplementing what I need because the API from the famous libraries aren't efficient. In general I'd love to send a million of requests all in the same packet and get the replies. No need to wait for the first reply to send the 2nd request and so on. They can all be on the same TCP packet but I have never met a library that lets me do that.
So for example while http3 should be more efficient and faster, since no library I've tried let me do this, I ended up using HTTP1.1 as usual and being faster as a result.
I spend 3 years developing Niquests, and believe me, HTTP is far from easy. Being a client means you have to speak to everyone, and no one have to speak to you (RFC are nice, but in practice never applied as-is). Once you go deep under the implementation, you'll find a thousand edge cases(...). And yes, the myth that as developer http/1 is "best" only means that the underlying scheduler is weak.
today, via a dead simple script, you'll see http/2+ beat established giant in the http/1 client landscape. see https://gist.github.com/Ousret/9e99b07e66eec48ccea5811775ec1... if you are curious.
It is indeed a shame that niquests isn't used more, I think trying to use the (c'est Français) argument to in French will bring you many initial users needed for the inertia
No Trio support yet, right? That’s the main reason to use httpx for me at least, and has been since I first typed “import httpx” some years ago.
(Also the sponsorship subscription thing in the readme gives me vague rugpull vibes. Maybe I’ve just been burned too much—I don’t mean to discourage selling support in general.)
help for getting it working is appreciated, we have it in mind.
duly noted about the sponsorship, we accept constructive criticism, and alternative can be considered.
it's the gitmoji thing, I really don't like it, it was a mistake. Thinking to stop it soon. I was inspired by fastapi in the early days. I prefer conventionalcommits.org
Please don't be too much inspired by FastAPI - at least regarding maintainer bus factor and documentation (FastAPI docs are essentially tutorial only), and requiring dozens of hoops to jump through to even open an issue.
I think that it owes its success to be first "port" of python requests to support async, that was a strong need.
But otherwise it is bad: API is not that great, performance is not that great, tweaking is not that great, and the maintainer mindset is not that great also.
For the last point, few points were referenced in the article, but it can easily put your production project to suddenly break in a bad way without valid reason.
Without being perfect, I would advise everyone to switch to Aiohttp.
I literally the other week had the choice between using requests and httpx. I chose httpx after deliberating a bit. I don't need async capabilities right now but I figured it'll be more consistent if that changes later.
aiohttp is an excellent library. very stable. I concurs, but!
it's too heavily tied to HTTP/1, and well, I am not a fan of opening thousands of TCP conn just to keep up with HTTP/2 onward. niquests easily beat aiohttp just using 10 conn and crush httpx see https://gist.github.com/Ousret/9e99b07e66eec48ccea5811775ec1...
>thread to call out Read the Docs for profiting from MkDocs without contributing back.
>They also point out that not opening up the source code goes against the principles of Open Source software development
I will never stop being amused when people have feelings like this and also choose licenses like BSD (this project). If you wanted a culture that discouraged those behaviors, why would you choose a license that explicitly allows them? Whether you can enforce it or not, the license is basically a type of CoC that states the type of community you want to have.
The reason is simple: they'd like to reap all the benefits of a permissive licence (many people and companies won't or can't touch GPL code), without any of the downsides; but these downsides are the very reason behind the rules in more 'restrictive' licenses like the GPL.
This usually doesn't work, and in the end all they can do is complain about behaviours that their license choice explicitly allowed.
Yes I agree completely. I am baffled why they choose that license in the first place. It just seems to engender drama when people actually follow the license they've chosen! Perhaps open source is actually powered by drama, where developers have more meaning from the drama they create than the actual things they create?
On one hand, that account of the attempted project takeover smelled to me like Jia Tan.
On the other hand, the comments the MkDocs author is making about perceived gender grievances feel so unhinged that I wouldn't be touching anything made by them with a barge pole.
Yes, I know you can be legit, but when you first contribute a few useful things, then jump to maintainership and want keys to the kingdom, the pattern looks similar (sans the last step which is embedding some backdoor). At least in how the article described it.
Right, my suspicion was correct. When I interacted with them a few years ago they seemed perfectly nice and friendly, but seem to have gone off the rails more recently. It's an uncomfortable situation and I've a feeling people are afraid to discuss this kind of thing but we really need to. People are a risk factor in software projects and we need to be resilient to changes they face. Forking is the right way, but places like GitHub have sold people on centralisation. We need to get back to decentralised dev.
> but places like GitHub have sold people on centralisation. We need to get back to decentralised dev.
I don’t think that’s the case. It’s more of a marketing/market incentive. It’s great pr to be associated with the most famous project, way less so to be associated with a fork, at least until the fork becomes widespread and well recognised.
GitHub does make it fairly easy to fork a project, I wouldn’t blame the situation on github.
I think that may be the first time I've seen licensing drama over something as minor as adding another author to the copyright list.
Pretty sure those are completely standard for major changes in maintainers/hostile forks/acknowledging major contributors. I've seen a lot of abandoned MIT/BSD projects add a new line for forks/maintainers being active again in order to acknowledge that the project is currently being headed by someone else.
From my "I am not a lawyer" view, Kludex is basically correct, although I suppose to do it "properly", he might need to just duplicate the license text in order to make it clear both contributors licensed under BSD 3-clause. Probably unnecessary though, given it's not a license switch (you see that style more for ie. switching from MIT to BSD or from MIT/BSD to GPL, since that's a more substantial change); the intent of the license remains the same regardless and it's hard to imagine anyone would get confused.
I suspect (given the hammering on it in responses), that Kludex asking ChatGPT if it was correct is what actually pissed off the original developer, rather than the addition of Kludex to the list in and of itself.
The original author said they were “the license holder”, specifically with a “the”, in discussions around both Starlette and MkDocs, which yes, just isn’t true even after rounding the phrase to the nearest meaningful, “the copyright holder”. This appears to be an honest misconception of theirs, so, not the end of the world, except they seem to be failing at communication hard enough to not realize they might be wrong to begin with.
Note though that with respect to Starlette this ended up being essentially a (successful and by all appearances not intentionally hostile?) project takeover, so the emotional weight of the drama should be measured with respect to that, not just an additional copyright line.
I guess you mean htmx. Same here. I read the article for a while, and was confused by "HTTPX is a very popular HTTP client for Python." and wondering "why is OpenAI using htmx", until I eventually realized what's going on.
This sounds like an ideal use case for modshim [0]
One of its intended use cases is bridging contribution gaps: while contributing upstream is ideal, maintainers may be slow to merge contributions for various reasons. Forking in response creates a permanent schism and a significant maintenance burden for what might be a small change. Modshim would allow you to create a new Python package containing only the fixes for your bugbears, while automatically inheriting the rest from upstream httpx.
Since modshim isn't money patching and appears to only be wrapping the external API of a package, if the change is deep enough inside the package, wouldn't you end up reimplementing most of the package from the outside?
Modshim does more than just wrap the external API of a package - it allows you to tweak something internal to the module while leaving its interface alone, without having to re-implement most of the package in order to re-bind new versions of objects.
There are a couple of example of this readme: (1) modifing the TextWrapper object but then use it through the textwrap library's wrap() function, and (2) modifing the requests Session object, but then just using the standard requests.get(). Without modshim (using standard monkey-patching) you would have to re-implement the wrap and get methods in order to bind the new TextWrapper / Session classes.
Always remember that open-source is an author’s gift to the world, and the author doesn’t owe anything to anyone. Thus, if you need a feature that for whatever reason can’t or won’t go upstream, forking is just about the only viable option. Fingers crossed!
If "taking part in a huge ecosystem in a foundational role" means 'other people choosing to use your FOSS software', and I can't think of what else it would mean, then no, you have no obligation to do any of that.
FOSS means the right to use and fork. That's all it means. That's all it ever meant. Any social expectations beyond that live entirely in your imagination.
There is simply no responsibility an OSS maintainer has. They can choose to be responsible, but no one can force them. Eventually OSS licensing is THE solution at heart to solve this problem. Maintainers go rogue? Fork and move on.
But surprise, who is going to fork AND maintain? Filling in all the demands from the community, for potentially no benefit?
No one can force him to take the responsibility, just like no one can force anyone else to.
Right, frustration about the no strings attached sentiment for OSS devs. Of course you've no obligations for support or maintenance, but with increasing exposure responsibility grows as de facto ever more projects, people, softwares depend on you.
This doesn't come over night and this is a spectrum and a choice. From purely personal side project over exotic Debian package to friggin httpx with 15k Github stars and 100 million downloads a week the 46th most downloaded PyPI package!
If this shall work reasonably in any way, hou have to step up. Take money (as they do, https://github.com/sponsors/encode), search fellow maintainers or cede involvement - even if only temporarily.
I feel there should be support from the ecosystem to help with that. OpenJS Foundation seems doing great: https://openjsf.org/projects. The Python Software Foundation could not only host PyPI but offer assistance for the most important packages.
>> Of course you've no obligations for support or maintenance, but with increasing exposure responsibility grows as de facto ever more projects, people, softwares depend on you.
This is an oxymoron. Either you have obligations, or you don't. There's no such thing as having "no obligations" but also "growing responsibility".
I don't understand how you can possibly conclude that just because you've chosen to become dependent on some FOSS library, they owe you anything. You don't get to somehow impose obligations on other people by your choices. They get none of your profits, but they're somehow responsible to you for your business risks? Nonsense.
It is a condition of your use of the code that you've accepted its license, and FOSS licenses are CRYSTAL CLEAR (ALL CAPS) on what obligations or responsibilities the authors have towards you - none whatsoever. Your use of the software is contingent on your acceptance of that license.
If that lack of warranty poses an unacceptable business risk to you, go buy support. Pay a dev to fix the issues you're having, rather than inventing some fictitious responsibility they have to you to do it for free.
No. Even if it’s a central piece of infrastructure, any and all maintainership effort is still a token of good will of the maintainer – and needs to be appreciated, rather than expected.
If you need stronger guarantees, pay someone to deliver them.
A (hypothetical) professional propriety project at same scale would probably feed a handful of people, with much less stress. FOSS version is zero cash and exaggerated community demands. Dream job.
The lack of a well-maintained async HTTP client in Python's stdlib has been a pain point for a while. Makes sense someone eventually took it into their own hands
An async HTTP client in the stdlib would also be great for tools like pip, which could really benefit from doing more async work. One of the reasons that uv is much faster is precisely this.
I'm not a lawyer, but are there any potential trademark issues? AFAIK in general you HAVE to change the name to something clearly different. I consider it morally OK, and it's probably fine, but HTTPXYZ is cutting it close. It's too late for a rebrand, but IMO open-source people often ignore this topic a bit too much.
There are unregistered trademarks as well as registered ones. Usually the "TM" symbol is applied to unregistered trademarks, and the ® symbol for registered ones. Both enjoy protection, although it's generally an easier time in court when your trademark is registered.
Whether actively defending your trademark is actually required is a bit of a nuanced topic. Generally, trademarks can be lost through genericide (the mark becomes a generic term for the type of product) or abandonment. Abandonment happens when either the mark owner stops using the mark itself, or takes an action that weakens the mark. The question, then, is whether failing to defend infringing use constitutes a weakening action. Courts differ on this, and there is a large gray area between "we didn't immediately sue a local mom-and-pop shop" and "we allowed a rival company to use the mark erroneously across several states for years without taking action."
He would probably win in a legal case, but is he actually going to take it to court? I doubt it. Also I wouldn't be too offended about the name if I were him and for users it's better because it makes the link clearer.
I think if had named it HTTPX2 or HTTPY, that would be much worse because it asserts superiority without earning it. But he didn't.
Do you see yourself taking over httpcore as well as it's likely to have the same maintainership problem? It would certainly instill more confidence that this is a serious fork.
This certainly wouldn't be the first time an author of a popular library got a little too distracted on the sequel to their library that the current users are left to languish a bit.
It's a shame, httpx has so much potential to be the default Python http library. It's crazy that there isn't one really. I contributed some patches to the project some years ago now and it was a nice and friendly process. I was expecting a v1 release imminently. It looks like the author is having some issues which seem to afflict so many in this field for some reason. I notice they've changed their name since I last interacted with the project...
You try to touch low level HTTP with Python, and once you dive into both RFC2616 and Python deep enough, your brain is cooked, basically. Look at what happened to the author of requests, a textbook example.
Or maybe it is that your brain is cooked already, or is on the brink, and your condition attracts you to HTTP and Python, after which it basically has you.
The only way to not go bonkers is to design a library by commitee, so that the disease spreads evenly and doesn't hit any one individual with full force. The result will be ugly, but hopefully free of drama.
Yeah, it's a shame because otherwise the library is really nice and could have become the default HTTP library, but it feels like someone will manage to inject some weird behaviour soon and half the planet will be compromised

Yes it is, can't add anything here. There's a tradeoff between "do the simple thing" and "make all things possible", and Java chooses the second here.

Because this Authenticator is meant for prompting a user interactively. I concur that this is very confusing, but if you want a Bearer token, just set the header.
> why can't I just pass 20 or 20_000 or something? Do we really need another class and method here?
If you've ever dealt with time, you'll be grateful it's a duration and not some random int.
The boilerplate of not having sane defaults. .NET is much simpler:
Yeah, so much simpler,
"Common IHttpClientFactory usage issues"
https://learn.microsoft.com/en-us/dotnet/core/extensions/htt...
"Guidelines for using HttpClient"
https://learn.microsoft.com/en-us/dotnet/fundamentals/networ...
And this doesn't account for all gotchas as per .NET version, than only us old timers remember to cross check.
That's just an example. It does have defaults: https://docs.oracle.com/en/java/javase/11/docs/api/java.net.... (search for "If this method is not invoked")
Yeah this is all over Rust codebases too for good reason. The argument is that default params obfuscate behaviour and passing in a struct (in Rust) with defaults kneecaps your ability to validate parameters at compile time.
It does have defaults, the above example manually sets everything to show people reading the docs what that looks like.
What's wrong with Go's? I've never had any issues with it. Go has some of the best http batteries included of any language
I guess he never used Fiber's APIs lol
The stdlib may not be the best, but the fact all HTTP libs that matter are compatible with net/http is great for DX and the ecosystem at large.
Thr comment I replied to was talking about sending a http requests. Go’s server side net/http is excellent, the client side is clunky verbose and suffers from many of the problems that Python’s urllib does.
>Honestly the thing that consistently surprises me is that requests hasn't been standardised and brought into the standard library
Instead, official documentation seems comfortable with recommending a third party package: https://docs.python.org/3/library/urllib.request.html#module...
>The Requests package is recommended for a higher-level HTTP client interface.
Which was fine when requests were the de-facto-standard only player in town, but at some point modern problems (async, http2) required modern solutions (httpx) and thus ecosystem fragmentation began.
Well, the reason for all the fragmentation is because the Python stdlib doesn't have the core building blocks for an async http or http2 client in the way requests could build on urllib.
The h11, h2, httpcore stack is probably the closest thing to what the Python stdlib should look like to end the fragmentation but it would be a huge undertaking for the core devs.
Node now supports the Fetch API.
> dotnet's HttpClient is... fine.
Yes, and it's in the standard library (System namespace). Being Microsoft they've if anything over-featured it.
It's fine but it's sharp-edged, in that it's recommended to use IHttpClientFactory to avoid the dual problem of socket exhaustion ( if creating/destroying lots of HttpClients ) versus DNS caching outliving DNS ( if using a very long-lived singleton HttpClient ).
And while this article [1] says "It's been around for a while", it was only added in .NET Framework 4.5, which shows it took a while for the API to stabilise. There were other ways to make web requests before that of course, and also part of the standard library, and it's never been "difficult" to do so, but there is a history prior to HttpClient of changing ways to do requests.
For modern dotnet however it's all pretty much a solved problem, and there's only ever been HttpClient and a fairly consistent story of how to use it.
[1] https://learn.microsoft.com/en-us/dotnet/core/extensions/htt...
>"It's been around for a while"
is 14 years not a while?
requests is some janky layer onto of other janky layers. last thing you want in the stdlib.
it's called the STD lib for a reason...
Don't think it's Python-specific, it's humanity-specific and Python happens to be popular so it happens more often/ more publicly in Python packages.
httpx has async support (much like aiohttp), whereas urllib is blocking-only. If you need to make N concurrent requests, urllib requires N threads or processes.
I think the python maintainers are still feeling burnt by the consequences of the "batteries included" approach from the old times.
Most Python developers these days weren't even programming when the 2 -> 3 split happened. Unless you're referencing something else.
the batteries included approach is the stdlib that can do everything. turns out it’s hard to maintain and make good.
Python doesn't have a big company behind it
Everybody's got a different idea of what it means for a library to be "friendly" and "fully-featured" though. It's probably better to keep the standard library as minimal as possible in order to avoid enshrining bad software. Programming languages could have curated "standard distributions" instead that include all the commonly used "best practice" libraries at the time.
https://xkcd.com/927/
That situation should be avoided. People should have to create their own libraries until everyone empirically converges into a de facto standard that can then be made official.

Python makes everything so easy.

Bram's Law
The easier a piece of software is to write, the worse it's implemented in practice. Why? Easy software projects can be done by almost any random person, so they are. It's possible to try to nudge your way into being the standard for an easy thing based on technical merit, but that's rather like trying to become a hollywood star based on talent and hard work. You're much better off trading it all in for a good dose of luck.
This is why HTTP is a mess while transaction engines are rock solid. Almost any programmer can do a mediocre but workable job of extending HTTP, (and boy, have they,) but most people can't write a transaction engine which even functions. The result is that very few transaction engines are written, almost all of them by very good programmers, and the few which aren't up to par tend to be really bad and hardly get used. HTTP, on the other hand, has all kinds of random people hacking on it, as a result of which Python has a 'fully http 1.1 compliant http library which raises assertion failures during normal operation.
Remember this next time you're cursing some ubiquitous but awful third party library and thinking of writing a replacement. With enough coal, even a large diamond is unlikely to be the first thing picked up. Save your efforts for more difficult problems where you can make a difference. The simple problems will continue to be dealt with incompetently. It sucks, but we'll waste a lot less time if we learn to accept this fact.
The HTTP protocol is easy to implement the basic features but hard to implement a full version that is also efficient.
I've often ended up reimplementing what I need because the API from the famous libraries aren't efficient. In general I'd love to send a million of requests all in the same packet and get the replies. No need to wait for the first reply to send the 2nd request and so on. They can all be on the same TCP packet but I have never met a library that lets me do that.
So for example while http3 should be more efficient and faster, since no library I've tried let me do this, I ended up using HTTP1.1 as usual and being faster as a result.
I spend 3 years developing Niquests, and believe me, HTTP is far from easy. Being a client means you have to speak to everyone, and no one have to speak to you (RFC are nice, but in practice never applied as-is). Once you go deep under the implementation, you'll find a thousand edge cases(...). And yes, the myth that as developer http/1 is "best" only means that the underlying scheduler is weak. today, via a dead simple script, you'll see http/2+ beat established giant in the http/1 client landscape. see https://gist.github.com/Ousret/9e99b07e66eec48ccea5811775ec1... if you are curious.
the http landscape is rather scary lately in Python. instead of forking join forces... See Niquests https://github.com/jawah/niquests
I am trying to resolve what you've seen. For years of hard work.
It is indeed a shame that niquests isn't used more, I think trying to use the (c'est Français) argument to in French will bring you many initial users needed for the inertia
ahah, "en effet"! je m'en souviendrai.
more seriously, all that is needed is our collective effort. I've done my part by scarifying a lot of personal time for it.
I saw there are almost no bugs or things to contribute, are there other ways to help ?
yes, plenty! testing it extensively, finding edge bugs, (...) and of course: spread the word on other project to help increasing adoption.
No Trio support yet, right? That’s the main reason to use httpx for me at least, and has been since I first typed “import httpx” some years ago.
(Also the sponsorship subscription thing in the readme gives me vague rugpull vibes. Maybe I’ve just been burned too much—I don’t mean to discourage selling support in general.)
help for getting it working is appreciated, we have it in mind. duly noted about the sponsorship, we accept constructive criticism, and alternative can be considered.
We have switched to niquests in my company and yes I can confirm that it's 10x better than httpx :)
Did you have any warts when switching? httpx has been "fine" for me but this thread has me seriously considering changing to niquests.
nice to hear :)
Is it knee-quests or nigh-quests?
I've started seeing these emoji-prefixed commits lately now too, peculiar
it's the gitmoji thing, I really don't like it, it was a mistake. Thinking to stop it soon. I was inspired by fastapi in the early days. I prefer conventionalcommits.org
Please don't be too much inspired by FastAPI - at least regarding maintainer bus factor and documentation (FastAPI docs are essentially tutorial only), and requiring dozens of hoops to jump through to even open an issue.
agreed. as I said, it was a mistake from my end. and clearly looking to better myself.
There is a series of extensions for Vscode that add this functionality like https://github.com/ugi-dev/better-commits
ah ok, I am familiar with and not exactly against (non-emoji) commit message prefixes
I better start seeing some caterpillar emojis in your next commits or we're gonna have a real problem!
nee-quests, I am French native.
niquests as in "niquer" ?
J'aime bien, j'aime bien
I guess kind of obvious now noticing the rhyme
The basis of httpx is not very good at all.
I think that it owes its success to be first "port" of python requests to support async, that was a strong need.
But otherwise it is bad: API is not that great, performance is not that great, tweaking is not that great, and the maintainer mindset is not that great also. For the last point, few points were referenced in the article, but it can easily put your production project to suddenly break in a bad way without valid reason.
Without being perfect, I would advise everyone to switch to Aiohttp.
I literally the other week had the choice between using requests and httpx. I chose httpx after deliberating a bit. I don't need async capabilities right now but I figured it'll be more consistent if that changes later.
I started using the ports and adapters pattern and protocol for any packages that have replacements or concerns.
Basically treating HTTP requests as an orthogonal, or cross-cutting concern.
It is sometimes hard to tell if these upstream packages are stable or abandoned.
I should probably document my methodology so it can help others or at least have the chance to find out what mistakes or limitations they might have.
aiohttp is an excellent library. very stable. I concurs, but! it's too heavily tied to HTTP/1, and well, I am not a fan of opening thousands of TCP conn just to keep up with HTTP/2 onward. niquests easily beat aiohttp just using 10 conn and crush httpx see https://gist.github.com/Ousret/9e99b07e66eec48ccea5811775ec1...
fwiw, HTTP/2 is twelve years old, just saying.
aiohttp is for asynchronous contexts only
Thanks, I'll link to your project
Thank you. Appreciated, you're welcome here anytime.
Can confirm, more features, a breeze to switch.
Half-melded side projects just pollute PyPI more, you get less grief long-term by biting the bullet and shipping a fork that owns its tradeoffs.
More related drama: The Slow Collapse of MkDocs (https://fpgmaas.com/blog/collapse-of-mkdocs/)
>thread to call out Read the Docs for profiting from MkDocs without contributing back.
>They also point out that not opening up the source code goes against the principles of Open Source software development
I will never stop being amused when people have feelings like this and also choose licenses like BSD (this project). If you wanted a culture that discouraged those behaviors, why would you choose a license that explicitly allows them? Whether you can enforce it or not, the license is basically a type of CoC that states the type of community you want to have.
The reason is simple: they'd like to reap all the benefits of a permissive licence (many people and companies won't or can't touch GPL code), without any of the downsides; but these downsides are the very reason behind the rules in more 'restrictive' licenses like the GPL.
This usually doesn't work, and in the end all they can do is complain about behaviours that their license choice explicitly allowed.
Yes I agree completely. I am baffled why they choose that license in the first place. It just seems to engender drama when people actually follow the license they've chosen! Perhaps open source is actually powered by drama, where developers have more meaning from the drama they create than the actual things they create?
On one hand, that account of the attempted project takeover smelled to me like Jia Tan.
On the other hand, the comments the MkDocs author is making about perceived gender grievances feel so unhinged that I wouldn't be touching anything made by them with a barge pole.
> On one hand, that account of the attempted project takeover smelled to me like Jia Tan.
Oleh was basically the sole maintainer for many years, and the development basically stopped when he left.
Yes, I know you can be legit, but when you first contribute a few useful things, then jump to maintainership and want keys to the kingdom, the pattern looks similar (sans the last step which is embedding some backdoor). At least in how the article described it.
Oh i recognised one of the involved people immediately, drama person.
I still think that hijacking the mkdocs package was the wrong way to go though.
The foss landscape has become way too much fork-phobic.
Just fork mkdocs and go over your merry way.
Right, my suspicion was correct. When I interacted with them a few years ago they seemed perfectly nice and friendly, but seem to have gone off the rails more recently. It's an uncomfortable situation and I've a feeling people are afraid to discuss this kind of thing but we really need to. People are a risk factor in software projects and we need to be resilient to changes they face. Forking is the right way, but places like GitHub have sold people on centralisation. We need to get back to decentralised dev.
Who are they?
> but places like GitHub have sold people on centralisation. We need to get back to decentralised dev.
I don’t think that’s the case. It’s more of a marketing/market incentive. It’s great pr to be associated with the most famous project, way less so to be associated with a fork, at least until the fork becomes widespread and well recognised.
GitHub does make it fairly easy to fork a project, I wouldn’t blame the situation on github.
Drama around Starlette. Drama around httpx. Drama around MkDocs. I just hope that DRF is not next, I still have some projects that depend on it.
Per TFA, there’s similarly-shaped low-key drama around DRF too[1] although issues and discussions have been reënabled since then.
[1] https://github.com/orgs/encode/discussions/11#discussioncomm...
What's the drama around starlette? (Can't find anything)
https://github.com/Kludex/starlette/issues/3180 and before that https://github.com/Kludex/starlette/issues/3042
I think that may be the first time I've seen licensing drama over something as minor as adding another author to the copyright list.
Pretty sure those are completely standard for major changes in maintainers/hostile forks/acknowledging major contributors. I've seen a lot of abandoned MIT/BSD projects add a new line for forks/maintainers being active again in order to acknowledge that the project is currently being headed by someone else.
From my "I am not a lawyer" view, Kludex is basically correct, although I suppose to do it "properly", he might need to just duplicate the license text in order to make it clear both contributors licensed under BSD 3-clause. Probably unnecessary though, given it's not a license switch (you see that style more for ie. switching from MIT to BSD or from MIT/BSD to GPL, since that's a more substantial change); the intent of the license remains the same regardless and it's hard to imagine anyone would get confused.
I suspect (given the hammering on it in responses), that Kludex asking ChatGPT if it was correct is what actually pissed off the original developer, rather than the addition of Kludex to the list in and of itself.
(Not a lawyer either but—)
The original author said they were “the license holder”, specifically with a “the”, in discussions around both Starlette and MkDocs, which yes, just isn’t true even after rounding the phrase to the nearest meaningful, “the copyright holder”. This appears to be an honest misconception of theirs, so, not the end of the world, except they seem to be failing at communication hard enough to not realize they might be wrong to begin with.
Note though that with respect to Starlette this ended up being essentially a (successful and by all appearances not intentionally hostile?) project takeover, so the emotional weight of the drama should be measured with respect to that, not just an additional copyright line.
If this would be a tv show I probably would view it, but wow what a drama.
Somehow I confused httpx with htmlx
I guess you mean htmx. Same here. I read the article for a while, and was confused by "HTTPX is a very popular HTTP client for Python." and wondering "why is OpenAI using htmx", until I eventually realized what's going on.
And also htmlx with htmx I guess?
I've been reading the whole article wrong too.
Same! Only just realized it thanks to your comment.
I thought your comment was starting with "Samuel". Plenty of people on sick leave as of late - must be difficult for many to focus their sight.
This sounds like an ideal use case for modshim [0]
One of its intended use cases is bridging contribution gaps: while contributing upstream is ideal, maintainers may be slow to merge contributions for various reasons. Forking in response creates a permanent schism and a significant maintenance burden for what might be a small change. Modshim would allow you to create a new Python package containing only the fixes for your bugbears, while automatically inheriting the rest from upstream httpx.
[0] https://github.com/joouha/modshim
Since modshim isn't money patching and appears to only be wrapping the external API of a package, if the change is deep enough inside the package, wouldn't you end up reimplementing most of the package from the outside?
Modshim does more than just wrap the external API of a package - it allows you to tweak something internal to the module while leaving its interface alone, without having to re-implement most of the package in order to re-bind new versions of objects.
There are a couple of example of this readme: (1) modifing the TextWrapper object but then use it through the textwrap library's wrap() function, and (2) modifing the requests Session object, but then just using the standard requests.get(). Without modshim (using standard monkey-patching) you would have to re-implement the wrap and get methods in order to bind the new TextWrapper / Session classes.

Congratulations on forking!
Always remember that open-source is an author’s gift to the world, and the author doesn’t owe anything to anyone. Thus, if you need a feature that for whatever reason can’t or won’t go upstream, forking is just about the only viable option. Fingers crossed!
This is not merely open-source, but taking part in a huge package ecosystem in a foundational role in an XKCD 2347 type of way for HTTP requests.
Put your side project on your personal homepage and walk away - fine.
Make it central infrastructure - respond to participants or extend or cede maintainership.
If "taking part in a huge ecosystem in a foundational role" means 'other people choosing to use your FOSS software', and I can't think of what else it would mean, then no, you have no obligation to do any of that.
FOSS means the right to use and fork. That's all it means. That's all it ever meant. Any social expectations beyond that live entirely in your imagination.
I guess frustration speaks here?
There is simply no responsibility an OSS maintainer has. They can choose to be responsible, but no one can force them. Eventually OSS licensing is THE solution at heart to solve this problem. Maintainers go rogue? Fork and move on. But surprise, who is going to fork AND maintain? Filling in all the demands from the community, for potentially no benefit?
No one can force him to take the responsibility, just like no one can force anyone else to.
Right, frustration about the no strings attached sentiment for OSS devs. Of course you've no obligations for support or maintenance, but with increasing exposure responsibility grows as de facto ever more projects, people, softwares depend on you.
This doesn't come over night and this is a spectrum and a choice. From purely personal side project over exotic Debian package to friggin httpx with 15k Github stars and 100 million downloads a week the 46th most downloaded PyPI package!
If this shall work reasonably in any way, hou have to step up. Take money (as they do, https://github.com/sponsors/encode), search fellow maintainers or cede involvement - even if only temporarily.
An example of a recent, successful transition is UniGetUI https://github.com/Devolutions/UniGetUI/discussions/4444
I feel there should be support from the ecosystem to help with that. OpenJS Foundation seems doing great: https://openjsf.org/projects. The Python Software Foundation could not only host PyPI but offer assistance for the most important packages.
>> Of course you've no obligations for support or maintenance, but with increasing exposure responsibility grows as de facto ever more projects, people, softwares depend on you.
This is an oxymoron. Either you have obligations, or you don't. There's no such thing as having "no obligations" but also "growing responsibility".
I don't understand how you can possibly conclude that just because you've chosen to become dependent on some FOSS library, they owe you anything. You don't get to somehow impose obligations on other people by your choices. They get none of your profits, but they're somehow responsible to you for your business risks? Nonsense.
It is a condition of your use of the code that you've accepted its license, and FOSS licenses are CRYSTAL CLEAR (ALL CAPS) on what obligations or responsibilities the authors have towards you - none whatsoever. Your use of the software is contingent on your acceptance of that license.
If that lack of warranty poses an unacceptable business risk to you, go buy support. Pay a dev to fix the issues you're having, rather than inventing some fictitious responsibility they have to you to do it for free.
No. Even if it’s a central piece of infrastructure, any and all maintainership effort is still a token of good will of the maintainer – and needs to be appreciated, rather than expected.
If you need stronger guarantees, pay someone to deliver them.
A foundational role in a huge open-source package ecosystem? I wonder what such an esteemed position pays.
A (hypothetical) professional propriety project at same scale would probably feed a handful of people, with much less stress. FOSS version is zero cash and exaggerated community demands. Dream job.

"So what is the plan now?" - "Move a little faster and not break things"
The lack of a well-maintained async HTTP client in Python's stdlib has been a pain point for a while. Makes sense someone eventually took it into their own hands
An async HTTP client in the stdlib would also be great for tools like pip, which could really benefit from doing more async work. One of the reasons that uv is much faster is precisely this.
I'm not a lawyer, but are there any potential trademark issues? AFAIK in general you HAVE to change the name to something clearly different. I consider it morally OK, and it's probably fine, but HTTPXYZ is cutting it close. It's too late for a rebrand, but IMO open-source people often ignore this topic a bit too much.
Don't you need to register and actively defend you trademark for it to apply?
There are unregistered trademarks as well as registered ones. Usually the "TM" symbol is applied to unregistered trademarks, and the ® symbol for registered ones. Both enjoy protection, although it's generally an easier time in court when your trademark is registered.
Whether actively defending your trademark is actually required is a bit of a nuanced topic. Generally, trademarks can be lost through genericide (the mark becomes a generic term for the type of product) or abandonment. Abandonment happens when either the mark owner stops using the mark itself, or takes an action that weakens the mark. The question, then, is whether failing to defend infringing use constitutes a weakening action. Courts differ on this, and there is a large gray area between "we didn't immediately sue a local mom-and-pop shop" and "we allowed a rival company to use the mark erroneously across several states for years without taking action."
In this case, the name is already so generic that you might even be denied a trademark in the first place.
I don't think HTTPX is a registered trademark.
Is httpx trademarked? I couldn't find anything indicating it was.
He would probably win in a legal case, but is he actually going to take it to court? I doubt it. Also I wouldn't be too offended about the name if I were him and for users it's better because it makes the link clearer.
I think if had named it HTTPX2 or HTTPY, that would be much worse because it asserts superiority without earning it. But he didn't.
Another abandoned project hurting users: https://github.com/benweet/stackedit
Do you see yourself taking over httpcore as well as it's likely to have the same maintainership problem? It would certainly instill more confidence that this is a serious fork.
This certainly wouldn't be the first time an author of a popular library got a little too distracted on the sequel to their library that the current users are left to languish a bit.
Hi Michiel!
Just a small headsup: clicking on the Leiden Python link in your About Me page give not the expected results.
And a small nitpick: it's "Michiel's" in English (where it's "Michiels" in Dutch).
Thanks for devoting time to opensource... <3
thanks, I hope I fixed the https://pythonleiden.nl website now
It's a shame, httpx has so much potential to be the default Python http library. It's crazy that there isn't one really. I contributed some patches to the project some years ago now and it was a nice and friendly process. I was expecting a v1 release imminently. It looks like the author is having some issues which seem to afflict so many in this field for some reason. I notice they've changed their name since I last interacted with the project...
You try to touch low level HTTP with Python, and once you dive into both RFC2616 and Python deep enough, your brain is cooked, basically. Look at what happened to the author of requests, a textbook example.
Or maybe it is that your brain is cooked already, or is on the brink, and your condition attracts you to HTTP and Python, after which it basically has you.
The only way to not go bonkers is to design a library by commitee, so that the disease spreads evenly and doesn't hit any one individual with full force. The result will be ugly, but hopefully free of drama.
smells like supply chain attack
Yeah, it's a shame because otherwise the library is really nice and could have become the default HTTP library, but it feels like someone will manage to inject some weird behaviour soon and half the planet will be compromised
