Removed the mention of "package index options" in the docs, because they don't all fit that category anymore. Not even --no-binary and --only-binary do; they're "install options".
We purposely keep it off the CLI for now. optparse isn't really geared to expose interspersed args and options, so a more heavy-handed approach will be necessary to support things like `pip install SomePackage --sha256=abcdef... OtherPackage --sha256=012345...`.
This adds constraints files. Like requirements files constraints files
control what version of a package is installed, but unlike
requirements files this doesn't itself choose to install the package.
This allows things that aren't explicitly desired to be constrained if
and only if they are installed.
and adjust the logic to match; the result is simpler.
2) Due to #1, we can remove some hairy "format_control" hacks
3) Due to #1, we have to relax the parsing and allow:
- multiple options per line
- any supported option on a line with a requirement (not just
--install-option/--global-option, although they are the only
options that are passed into a requirement)
Using --install-options, --build-options, --global-options changes
the way that setup.py behaves, and isn't honoured by the wheel code.
The new wheel autobuilding code made this very obvious - disable
the use of wheels when these options are supplied.
With wheel autobuilding in place a release blocker is some granular
way to opt-out of wheels for known-bad packages. This patch introduces
two new options: --no-binary and --only-binary to control what
archives we are willing to use on both a global and per-package basis.
This also closes#2084
Wheel cache lookups become more complex when we wish to allow binary
blacklisting. Rather than passing more parameters around, replace
cache_root with wheel_cache, and create a wheel cache in all the
relevant command entry points.
two major changes:
1) re-use the optparse options in pip.cmdoptions instead of maintaining
a custom parser
2) as a result of #1, simplify the call stack
from: parse_requirements -> parse_content -> parse_line
to: parse_requirements -> process_line
beyond #1/#2, minor cosmetics and adjusting the tests to match
This allows lines such as the following to exist in requirements files:
INITools==0.2 --install-options="--prefix=/opt"
virtualenv>=1 --global-options="--no-user-cfg"
In addition, the requirements file parser was overhauled with simplicity
and clarity in mind.
- no need to check for startswith('#') since the regex removed all
comments
- make sure the regex removes all spaces before the comment
- remove all long prefixes the same way
- only lstrip short options since the line has already been stripped
