Description

This is what I get when I try to upgrade PHP from 7.4.26 to 7.4.27 using FreeBSD ports:

=> php-7.4.27.tar.xz doesn't seem to exist in /usr/ports/distfiles//.
=> Attempting to fetch https://www.php.net/distributions/php-7.4.27.tar.xz
fetch: https://www.php.net/distributions/php-7.4.27.tar.xz: Service Unavailable
=> Attempting to fetch http://distcache.FreeBSD.org/ports-distfiles/php-7.4.27.tar.xz
fetch: http://distcache.FreeBSD.org/ports-distfiles/php-7.4.27.tar.xz: Not Found
=> Couldn't fetch it - please try to retrieve this
=> port manually into /usr/ports/distfiles// and try again.

FreeBSD ports uses "fetch" to download https://www.php.net/distributions/php-7.4.27.tar.xz but looks like www.php.net web-server blocks user agent "fetch libfetch/2.0" and returns "Service Unavailable".

Can you whitelist this user agent?

PHP Version

PHP 7.4

Operating System

curl -A "fetch libfetch/2.0" --output php-7.4.27.tar.xz https://www.php.net/distributions/php-7.4.27.tar.xz works for me. What am I missing?

Is this possibly certificate related?

I can confirm:

❯ fetch https://www.php.net/distributions/php-7.4.27.tar.xz
fetch: https://www.php.net/distributions/php-7.4.27.tar.xz: Service Unavailable

fetch -vvvv https://www.php.net/distributions/php-7.4.27.tar.xz - doesn't. It successfully establishes connection and then fails:

Ah, so this would be a systems issue. Maybe @saschaschumann can have a look?

Fix fetch for php*
529117f 
- Primary hosting provider of php has introduced some sort of checking
  which is blocking fetch although curl/wget works perfectly. fetch with
  other --user-agent is also not working at the moment. An issue has been
  opened with the upstream which can be found at:
  php/web-php#483
- Untill this is fixed add php Github distributions URL to MASTER_SITES
- Modify MASTER_SITES for php[73|74|80] and remove SUBDIR as it affects
  DIST_SUBDIR
- Add DIST_SUBDIR as Github is IPv4 only which affects IPv6 only
  builders. In case someone is running IPv6 only builders distcache will
  pickup and serve.
- Although distinfo has been updated as we have added DIST_SUBDIR but
  SHA256 and SIZE are unchanged. In case someone needs to verify those
  are available from https://www.php.net/downloads
- We might have done some drastic changes but we are on the brink of
  quarterly build and we do not want to start a new year and a new
  quarter with BROKEN php and thousands of other ports.

In case someone is already investigating I believe the problem is with http1.1 vs http2. In case we try curl with --http1.1 it also fails with the same errors.
