#curl

Did you know that YOU can sponsor this year's #curl up? curl up is the annual curl developers meetup, this year taking place in May in Prague.

You can have your company name associated with the event while at the same time funding critical Internet infrastructure and one of the world's most widely used software components.

Just saying.

I had forgotten this. Six years ago I researched the Refresh HTTP header field and came to the conclusion that #curl doesn't need to bother.

Looking for the Refresh header

The other day someone filed a bug on curl that we don't support redirects with the Refresh header. This took me down a rabbit hole of Refresh header research and I've returned to share with you what I learned down there.

Two years since the big #curl 25 year celebration I'm looking at project numbers from back then and compare them with current ones.

19,800 more lines of code

23 additional man pages

428 new test cases

83 more CI jobs

229 new authors

30,800 USD more in bug bounties

18 new command line options

14 more operating systems

4557 commits more

We're not slowing down.

I like #curl. I am using curl on the command-line while working on software projects and Hammer curl turing workout.

Raised an issue to discuss how to improve curl's MQTT message output.

github.com/curl/curl/issues/16…

Comments and insight requested to plan a possible PR as I can't see a way to fix it without it being a breaking change to current behaviour.

#curl #MQTT


No way to parse multiple MQTT messages from the output stream · Issue #16633 · curl/curl

I did this I ran curl mqtt://test.mosquitto.org/curl/test --output test.out -N Then in a different terminal curl mqtt://test.mosquitto.org/curl/test -d "helloWorld" curl mqtt://test.mosquitto.org/c...

Remember: when you run #curl shipped by Apple with the --cacert flag it won't behave like #curl does everywhere else. As I wrote about last year. I think they're doing it wrong. They think its fine.

the Apple curl security incident 12604

tldr: Apple thinks it is fine. I do not. On December 28 2023, bugreport 12604 was filed in the curl issue tracker. We get a lot issues filed most days so this fact alone was hardly anything out of the ordinary.

There was a question posed on the #curl IRC channel whether there's ever going to be a need to raise addressing or offsets from 64-bit to something larger, such as 128-bit.

I argue there is no need to do this. 64-bit can already address a very large amount of data. For example, many operating systems and filesystems have a limit of 2**64 for file sizes. But it is difficult to wrap your head around this; how much data can such a file really hold?

Some estimates (*) say that there's going to be around 181 ZB (zettabytes) of data in the world by the end of 2025.

This is only 9812 files if each file holds 2**64 bytes.

Big data statistics: How much data is there in the world?

Data is growing at a faster rate than ever before. 90% percent of the world’s data was created in the last two years. And every two years, the volume of data across the world doubles in size.

Ten years ago on this day we went full GitHub model in #curl: pull-request style development. We have since handled over 10,700 PRs in an increasing amount of activity.

created issues + pull-requests on GitHub per months since 2015, showing a growing trend

curl: embracing github more

Pull requests and issues filed on github are most welcome! The curl project has been around for a long time by now and we've been through several different version control systems.

@thomas_klopf sometimes you must really want to get something done and put in the extra effort to make sure it happens. Being captain of the #curl ship takes me to many such places...

Today is also two years since "the nuget story" where I struggled to get a ten year old and vulnerable #curl version delisted:

The curl nuget story

If you use a curl built with GnuTLS (debian sid, for example), specifying --ciphers now does nothing.

But some people have need of that option to work. Here you can chime in on how it should be supported:

TLS ciphers and GnuTLS priorities · curl curl · Discussion #16364

Some people migrating from curl+openssl to a curl+gnutls notice that their --ciphers arguments simply are ignored. First, this is documented and not a bug. Fine. But some of these users have a need...

@wolf480pl I'm neutral on this. I'm mostly observing and thinking about how this will/should impact #curl if it gets adopted for real.
