Some elf files (e.g. created by rust compiler) have INTERP header despite
their magic header denotes shared object instead of executable.
We should relocate the interpreter elf files as long as they have INTERP header.
This should fix the broken bottles for rust based formulae.
This is a developer-only feature, so it's gated via `HOMEBREW_DEVELOPER`.
This is intended to enable testing of macOS 10.15; users building software
manually to test compatibility of early betas need to be able to build
software from source instead of via pouring 10.14 bottles. This isn't
intended to be a general-purpose `HOMEBREW_BUILD_FROM_SOURCE` replacement,
and has no effect on released versions of macOS.
- I tried to install `keybase`, thinking I'd get the CLI. On Linux,
casks don't work, yet I was still prompted to `brew cask install
keybase`. When I tried that (just to make sure), I got the "casks are
only supported on MacOS" error.
- This change makes it so we don't prompt people to install casks if
they're on platforms other than MacOS.
Before:
```
╭─issyl0@grus /home/linuxbrew/.linuxbrew/Homebrew ‹master›
╰─ $ brew install keybase
Error: No available formula with the name "keybase"
Found a cask named "keybase" instead.
```
After:
```

- Accelerate provides more than just BLAS and LAPACK functionality, see
https://developer.apple.com/documentation/accelerate
- Veclibfort exists only to wrap Accelerate's BLAS/LAPACK
- LAPACK is a slow, seldom updated reference implementation
- Encourage usage of OpenBLAS
- Reverts PR #6130
- veclibfort exists soley to wrap Apple's accelerate and provide BLAS/LAPACK
access to Accelerate
- Improve the help message for that audit to mention veclibfort
Recent commit 36dbad3922 to default to frozen string literals (via `frozen_string_literal`) broke `check_for_unsupported_macos()` on outdated releases--due to attempted modification of a frozen string literal.
This breaks `install` and `doctor`.
It's like the change wasn't tested on an unsupported outdated release or something... :D
Adding a `+` prefix is apparently one way around this issue according to https://stackoverflow.com/questions/37799296/what-does-the-comment-frozen-string-literal-true-do#37799399. The change worked for me.
Combined with https://github.com/Homebrew/homebrew-test-bot/pull/247
this will test Homebrew's use of frozen strings in CI. After this we
will then enable it for Homebrew developers and eventually all Homebrew
users.
This restores the original file uid, gid and permissions separately.
(ActiveSupport does it in a single step - atomically. This is not
useful in our use case because it may lead to ACL changes.)
Fixes#5916
Integration tests are useful in detecting breakages but much slower so
let's only use one per command and install formula outside the
integration test framework (which is also slow).
