When DownloadStrategyDetector.detect is given a second argument, and
that argument is not a symbol or an AbstractDownloadStrategy subclass,
it is silently ignored, and we fall back to guessing the strategy based
on the URL.
This means I can do
url 'http://foo.com/bar.tar.gz', :using => Class.new
and things will appear to work, even though I have clearly passed an
invalid value for :using.
A more useful behavior is to raise an exception for unknown strategy
specifications.
gunzip can only extract files in-place, so just shelling out to
gunzip was actually leaving the uncompressed file in Homebrew's cache,
not in the temporary directory. (It also destroyed the original
compressed file.)
Strip `?` and trailing characters from URL extensions and basenames.
This makes some install methods cleaner, and prevents staging of files
with `?` in the name, as that is a weird character.
Affects 2 formulae in core (though potentially externals will need to be fixed.)
Also allow to build with --HEAD by making brew's
download strategy aware of a brewed but unlined hg.
Adapted the caveats so that the procedure to brew
hg --HEAD is clear.
Mention how to config hgk in the caveats.
New `depends_on :python` Dependency.
New `depends_on :python3` Dependency.
To avoid having multiple formulae with endings -py2 and -py3,
we will handle support for different pythons (2.x vs. 3.x)
in the same formula.
Further brewed vs. external python will be transparently supported.
The formula also gets a new object `python`, which is false if
no Python is available or the user has disabled it. Otherwise
it is defined and provides several support methods:
python.site_packages # the site-packages in the formula's Cellar
python.global_site_packages
python.binary # the full path to the python binary
python.prefix
python.version
python.version.major
python.version.minor
python.xy # => e.g. "python2.7"
python.incdir # includes of python
python.libdir # the python dylib library
python.pkg_config_path # used internally by brew
python.from_osx?
python.framework?
python.universal?
python.pypy?
python.standard_caveats # Text to set PYTHONPATH for python.from_osx?
python.if3then3 # => "" for 2.x and to "3" for 3.x.
Further, to avoid code duplication, `python` takes an optional
block that is run twice if the formula defines depends_on
:python AND :python3.
python do
system python, 'setup.py', "--prefix=#{prefix}"
end

If an incomplete download exists, and the HTTP server doesn't support
byte ranges, delete the incomplete download and retry once.
Tested with freeling, whose server does not support byte ranges.

After converting to Pathname to create paths, using '+=' will result in
path concatenation by '/', which result in weird path like
'gcc--svn/-HEAD'. This patch should fix this.

We should handle this case in some predictable way, but until we do,
let's raise a more appropriate exception. It would also be good to get
rid of the duplication here.
When we are building from a tag, and that tag is already present in the
cached repository, we don't to hit the network; everything we need
already exists.
