Simple repro:
>curl -vI --http1.1 https://example.com/[1-3] -H"Connection:close"
output of the old CURL version contains "* SSL re-using session ID";
output of 7.77.0 does not. Wireshark confirms that the old version
sent PSK in client hello, the new version did not.
curl 7.77 downloaded here:
Hello,
Would it be a good time to start a stable (long-term support) version?
Like in, version 7 would still get bug fixes, but no new features, and
would be maintained until version 9 (or 10) goes out.

Daniel

Well then, I'd vote in favor of not allowing pause when
CURLMOPT_PIPELINING is set to anything other than CURLPIPE_NOTHING.
I'm not a fan of changes that may negatively impact performance, as
you may guess. And I never used pause anyway.
Regards,
Daniel
Sounds like the problem HPN-SSH tried to solve:
https://www.psc.edu/index.php/hpn-ssh/638
I like their approach, but I'm not sure how they got hold of the
current TCP receive window size; the only value I could find was
receive buffer size, which is not necessarily relevant here.

Hi all,
I see that libcurl supports SSL session ID cache already, unless
CURLOPT_SSL_SESSIONID_CACHE is cleared. However, I'm having a hard
time finding information about the scope of session ID reuse:
- Are session IDs reused only within an easy handle or globally for
all handles within the

7.65 will be fine. Actually the first version with that feature was
7.61.1, but any version since then should be good.

Taras,
Thanks for pointing that out. The function looks good.
Buffer autotuning was only introduced in curl 7.61, so the app using
7.57 will use the default (slow) buffer sizes. You shouldn't need to
set UPLOAD_BUFFERSIZE to get good upload speeds on 7.65.1.
As for the connection timeout, it

I see. What's the performance of curl on the same connection?

I like that; if we had the sftp_write function acknowledge data as
soon as it is put in socket buffer, we could get much faster
transfers. In
Ok, so let's put Linux to a test.
0. Patch CURL:
#define UPLOAD_BUFSIZE (1<<19)
1. Create a large file. 1 TB looks good:
dd if=/dev/zero of=testfile bs=1 count=0 seek=1T
The file is sparse, so disk operations won't block us.
2. Upload to /dev/null:
curl -u user:pass -k sftp://127.0.0.1/dev/null -T

I don't think any URL parsing library cares about = beyond the first
one. Which is why = in name may pose a problem, but in value probably
won't. I'd skip all.

Well assuming we want to use the API to build URL based on HTML form
with GET action, curl_url_query_append suggested by Geoff would be
much nicer. In particular, I

Windows builds use schannel (Windows SSL implementation) by default;
with that you don't need CA bundle. Are you building with OpenSSL?
