From: Scott Worley Date: Fri, 14 Jan 2022 05:55:09 +0000 (-0800) Subject: Support restricted mode: Allow tarball access with search paths. X-Git-Tag: v3.0.6~3 X-Git-Url: http://git.scottworley.com/pinch/commitdiff_plain/436195f097c503546a7d1d80f4e82964bcdc7392 Support restricted mode: Allow tarball access with search paths. This allows 'pinch update' to create a new profile. Updating an existing profile still doesn't work because nix-env can't read the existing manifest. Also, the search path names aren't the best. Multiple links probably don't work in restricted mode. (This tool is deprecated & is receiving minimal maintenance; patches welcome.) --- diff --git a/Changelog b/Changelog index f6943ec..1bd1d9c 100644 --- a/Changelog +++ b/Changelog @@ -3,6 +3,7 @@ - Deprecate pinch. - Show the channel URL being fetched. - Use nix 2.3 because 2.4 broke . +- Support restricted mode: Allow tarball access with search paths. ## [3.0.5] - 2021-07-09 diff --git a/pinch.py b/pinch.py index 130f69a..2ba47b2 100644 --- a/pinch.py +++ b/pinch.py @@ -644,6 +644,7 @@ def pinCommand(args: argparse.Namespace) -> None: def updateCommand(args: argparse.Namespace) -> None: v = Verification() exprs: Dict[str, str] = {} + search_paths: List[str] = [] config = { section: read_pinned_config_section(section, conf) for section, conf in read_config_files( @@ -651,10 +652,12 @@ def updateCommand(args: argparse.Namespace) -> None: alias, nonalias = partition_dict( lambda k, v: isinstance(v[0], AliasSearchPath), config) - for section, (sp, pin) in nonalias.items(): + for section, (sp, pin) in sorted(nonalias.items()): assert not isinstance(sp, AliasSearchPath) # mypy can't see through assert not isinstance(pin, AliasPin) # partition_dict() tarball = sp.fetch(v, pin) + search_paths.extend(["-I", "pinch_tarball_for_%s=%s" % + (pin.release_name, tarball)]) exprs[section] = ( 'f: f { name = "%s";
