-This file is a simple placeholder for forcing the appveyor build cache
-to invalidate itself since appveyor.yml changes more frequently then
-the cache needs updating.  Note, the versions list here can be
-different than what is indicated in appveyor.yml.
-
-To invalidate the cache, update this file and check it into git.
-
-
-Currently used modules built in the cache:
-
- OPENSSL_VERSION: 1.1.1r
- POSTGRES_VERSION: 15.0
-
-
-NOTE: to zap the cache manually you can also use:
-
-	curl -X DELETE -H "Authorization: Bearer $APPVEYOR_TOKEN" -H "Content-Type: application/json" https://ci.appveyor.com/api/projects/psycopg/psycopg2/buildcache
-
-with the token from https://ci.appveyor.com/api-token

Brénainn Woodsend	d0bc154f31	build(macos): Enable cross compiling libpq across macOS architectures The GitHub Actions runners look like they're only 1 year away from the last macOS x86_64 platform being removed. Get ahead of the game and build x86_64 on arm64.	2025-01-05 20:44:25 +01:00

Brénainn Woodsend	d43e5fe092	ci(macos): Avoid linking against homebrew Homebrew binaries are always compiled for exactly the version they're installed on making them very un-portable. When a wheel is "repaired" by cibuildwheel, delocate-wheel pulls in _psycopg's dependencies (libpq.dylib, libssl.dylib and libcrypto.dylib) which, on a GitHub Actions macOS 14 runner, are provided by Homebrew and are therefore only macOS >= 14 compatible. The resultant wheel is therefore incompatible with all but the latest macOS versions. Build all dependencies from source so that we can set the deployment target to something sensible. Fixes #1753.	2025-01-04 21:23:15 +01:00
