Not quite a mass replacement as I've used OS X and Mac OS X where
describing specific older versions and added compatibility methods
for things in the DSL.
Migrate a HOMEBREW_REPOSITORY and HOMEBREW_PREFIX of `/usr/local` so
that the HOMEBREW_REPOSITORY is now in `/usr/local/Homebrew`. This gives
us more flexibility on changing the repository layout in future and
avoids putting junk in `/usr/local` when not necessary (e.g. our
`README.md`).
`name` is passed as argument to Formulary.factory which could later be
downcased at formulary.rb:349, but Pathname doesn't have a downcase
method. Converting `name` to String as it should be fixes the problem.
Fixes#1000.
Ensure that `brew update` always runs the LinkedKegs migration if needed
as it may not have been run by `brew update` if it was using `--preinstall` or
a `git pull` etc.
Also, if the old paths still exist: just use them instead.
Finally, always try to unlink/unpin before link/pin.
Fixes https://github.com/Homebrew/homebrew-core/issues/4918.
Software that tries to print different things (e.g. ANSI color) based on
different termcaps often relies on the TERM environment variable, and
could fail without it. This results in confusing test issues where
certain tests can be successfully run by users testing locally with TERM
set, but choke up on our CI.
Always setting TERM to dumb leads to better consistency between local
tests and CI tests, and saves much probing in certain cases.
OS X Travis CI is particularly error-prone, slow and unnecessary for
us when we're already running (fast) OS X builds on Jenkins so use it
just for Linux testing.
These definitions are scattered throughout the codebase which makes it
hard to refactor them later (my goal is to move them outside of
HOMEBREW_LIBRARY). Unify their definitions for clearer code and easier
movement later.
The GNU Autotools tests for whether a given symbol is defined are
reliably coming to incorrect conclusions on 10.11 with the 10.12 SDK
in Xcode 8. This overrides its decisions by forcing the right answer
in superenv using ac_cv_func_* environment variables and setting them to
"no" on 10.11. The list of problematic symbols is from
grep 'weak$os10.11' MacOSX.sdk/usr/lib/system/libsystem_c.tbd
Building gcc with --HEAD results in most of the executables not having a
version suffix, e.g. Building/installing gcc 6 would result in gcc-6,
g++-6, etc. being installed, while building/installing gcc --HEAD would
result in gcc-, g++-, etc. being installed.
The lack of a version suffix prevented brew from recognizing a valid gcc
install, resulting in brew instructing users to install gcc before
building certain formulae even though gcc is installed.
A patch to the gcc formula makes the version number for --HEAD builds
the major version number of the stable version + 1 (7 at this time).
This patch teaches brew to recognize current --HEAD builds as valid
compilers.
