cURL different behaviour between PHP 8.2.15 and PHP 8.2.16

[VinceT]

Just downloaded latest version of cURL (https://curl.se/windows/dl-8.6.0_2/curl-8.6.0_2-win64-mingw.zip).
Unfortunately for you, it works perfectly...

We did update the curl version for the Windows builds because of upstream security patches.
PHP 8.2.15 would have used libcurl 8.4 and PHP 8.2.16 uses libcurl 8.6.
Can you confirm you are using libcurl 8.6 and can you check whether you can reproduce the issue with the curl command line?

Hi,
I don't know how to check libcurl version. I guess I use the "php_curl.dll" which is packaged with each version. "Properties" of the files are not useful. The only difference is the file size : 8.2.15 = 665k vs 8.2.16 = 675k.
Both files (renamed) are attached in a zip file.
php_curl.zip

I launched the following curl command in a DOS console :
curl "http://localhost:8100/analytique" -I -H "Prefer: count=exact" -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJyb2xlIjoicGdiYW5xdWUifQ.HtTypposHWuwOhg0EIJy90GlrMo-xQnJPizF1Se3n4c"
And the result is (as expected) :
HTTP/1.1 200 OK
Date: Thu, 29 Feb 2024 15:18:35 GMT
Server: postgrest/12.0.2 (a4e00ff)
Content-Range: 0-36/37
Content-Location: /analytique
Content-Type: application/json; charset=utf-8
Preference-Applied: count=exact

The line that I parse to get the number of records is "Content-Range: 0-36/37"

Stupid me ! phpinfo gives the following for 8.2.15 :

cURL Information | 8.4.0

and for 8.2.16 :

cURL Information | 8.6.0

[VinceT]

PHP 8.2.16 + cURL 8.4.0 works like a charm.

[nielsdos]

PHP 8.2.16 + cURL 8.4.0 works like a charm.

Then it's either a curl problem or something wrong with our build.

Some questions :-)
When you tried the curl command in the DOS console, did you try version 8.4 or 8.6?
Does it not work all the time or only sometimes?
Are you able to set up a reproducing script?

1/ curl -V
curl 8.4.0 (Windows) libcurl/8.4.0 Schannel WinIDN
Release-Date: 2023-10-11
Protocols: dict file ftp ftps http https imap imaps pop3 pop3s smtp smtps telnet tftp
Features: AsynchDNS HSTS HTTPS-proxy IDN IPv6 Kerberos Largefile NTLM SPNEGO SSL SSPI threadsafe Unicode UnixSockets

2/ I guess it's only about PHP, not Windows.
8.4.0 : always OK (totals and details),
8.6.0 : details always OK, totals ("Prefer: count=exact") always KO.

3/ No idea of how to do that. Sorry.

[nielsdos]

Thanks for the answer. So you now tested it with curl 8.4 command line, which works. Can you test with curl 8.6 command line? If that doesn't work then it's not a problem at our side but a regression at curl and we should report it there then.

[nielsdos]

Okay thanks for checking.
I see the error gets emitted from inside libcurl, I'd have to try to reproduce the issue to figure out what's wrong.
