Bumps the minimum required libcurl version to 7.61.0.
Please also see #4917, which bumped minimum libcurl version to the current >= 7.29.0.
This bumps the minimum requirement to Curl 7.61.0 (released 2018 Sept).
Ubuntu, Debian, RHEL, and RHEL derivatives have major and LTS version bumps this year. Following are the
libcurl-dev/libcurl-devel versions available in the oldest supported (LTS or otherwise) in major OSs.
- Debian buster: [7.64](https://packages.debian.org/buster/libcurl4-openssl-dev)
- Ubuntu 20.04: [7.68](https://packages.ubuntu.com/focal/libcurl-dev)
- CentOS/RHEL 7: 7.29
- RHEL 8/Rocky 8/EL 8: 7.61
- Fedora 38: 7.87
RHEL/CentOS 7 reaches EOL mid 2024, so for PHP 8.4 scheduled towards the end of this year, we can safely
bump the minimum libcurl version.
7.61.0 was selected as the new minimum because RHEL and derivatives have libcurl-devel version 7.61. RHEL 8 is
a current and supported RHEL version.
The `sync_constants.php` file uncovers constants present in libcurl source, but\
not present in PHP ext/curl source. There is a regular expression to match
Curl constants, but to it did not previously include `CURLE_*` and `CURLINFO_*`
constants, which PHP should expose as constants.
This updates the `sync_constants.php` file's constant filter regex to expose those
constants patterns as well. The new missing constants will be added in a later PR.
`CURLOPT_XFERINFOFUNCTION` is available as of cURL 7.32.0, and
supersedes `CURLOPT_PROGRESSFUNCTION` which is still supported by
latest cURL, though.
Closes GH-7823.
This patch makes several scripts and PHP development tools files
executable and adds more proper shebangs to the PHP scripts.
The `#!/usr/bin/env php` shebang provides running the script via
`./script.php` and uses env to find PHP script location on the system.
At the same time it still provides running the script with a user
defined PHP location using `php script.php`.
The existence of the following functions is now guaranteed:
* curl_escape()
* curl_unescape()
* curl_multi_setopt()
libcurl 7.15.5 has been released 11.5 years ago and is available
even in RHEL 5.
