From: david-sarah Date: Fri, 28 Jan 2011 05:41:50 +0000 (-0800) Subject: src/allmydata/__init__.py: fix #1339, give an indication in the --version[-and-path... X-Git-Tag: trac-5000~6 X-Git-Url: https://git.rkrishnan.org/vdrive/install-details.html?a=commitdiff_plain;h=c71a19b9ed3bafe9931cb5a4deb446ea67afa3b9;p=tahoe-lafs%2Ftahoe-lafs.git src/allmydata/__init__.py: fix #1339, give an indication in the --version[-and-path] output of when the imported setuptools is distribute, and use a separate element in _vers_and_locs_list tuples for information other than the package name and location. This also changes slightly how the sqlite version is reported. --- diff --git a/src/allmydata/__init__.py b/src/allmydata/__init__.py index 8977bac2..c6f9dceb 100644 --- a/src/allmydata/__init__.py +++ b/src/allmydata/__init__.py @@ -182,17 +182,21 @@ def get_package_versions_and_locations(): __import__(modulename) module = sys.modules[modulename] except ImportError: - packages.append((pkgname, (None, modulename))) + packages.append( (pkgname, (None, None, modulename)) ) else: if 'sqlite' in pkgname: - packages.append( (pkgname, (get_version(module, 'version'), package_dir(module.__file__))) ) - packages.append( ('sqlite', (get_version(module, 'sqlite_version'), package_dir(module.__file__))) ) + packages.append( (pkgname, (get_version(module, 'version'), package_dir(module.__file__), + 'sqlite %s' % (get_version(module, 'sqlite_version'),))) ) else: - packages.append( (pkgname, (get_version(module, '__version__'), package_dir(module.__file__))) ) + comment = None + if pkgname == 'setuptools' and hasattr(module, '_distribute'): + # distribute does not report its version in any module variables + comment = 'distribute' + packages.append( (pkgname, (get_version(module, '__version__'), package_dir(module.__file__), comment)) ) elif pkgname == 'python': - packages.append( (pkgname, (platform.python_version(), sys.executable)) ) + packages.append( (pkgname, (platform.python_version(), sys.executable, None)) ) elif pkgname == 'platform': - packages.append( (pkgname, (get_platform(), None)) ) + packages.append( (pkgname, (get_platform(), None, None)) ) return packages @@ -207,9 +211,10 @@ def check_requirement(req, vers_and_locs): raise PackagingError("no version info for %s" % (name,)) if req.strip(' ') == name: return - (actual, location) = vers_and_locs[name] + (actual, location, comment) = vers_and_locs[name] if actual is None: - raise ImportError("could not import %r for requirement %r" % (location, req)) + # comment is the module name + raise ImportError("could not import %r for requirement %r" % (comment, req)) if actual == 'unknown': return actualver = normalized_version(actual) @@ -247,25 +252,35 @@ def cross_check_pkg_resources_versus_import(): from _auto_deps import install_requires errors = [] - not_pkg_resourceable = set(['sqlite', 'sqlite3', 'python', 'platform', __appname__.lower()]) + not_pkg_resourceable = set(['sqlite3', 'python', 'platform', __appname__.lower()]) not_import_versionable = set(['zope.interface', 'mock', 'pyasn1']) - ignorable = set(['argparse', 'pyutil', 'zbase32']) + ignorable = set(['argparse', 'pyutil', 'zbase32', 'distribute']) pkg_resources_vers_and_locs = dict([(p.project_name.lower(), (str(p.version), p.location)) for p in pkg_resources.require(install_requires)]) - for name, (imp_ver, imp_loc) in _vers_and_locs_list: + for name, (imp_ver, imp_loc, imp_comment) in _vers_and_locs_list: name = name.lower() if name not in not_pkg_resourceable: if name not in pkg_resources_vers_and_locs: - errors.append("Warning: dependency %s (version %s imported from %r) was not found by pkg_resources." - % (name, imp_ver, imp_loc)) + if name == "setuptools" and "distribute" in pkg_resources_vers_and_locs: + pr_ver, pr_loc = pkg_resources_vers_and_locs["distribute"] + if not (os.path.normpath(os.path.realpath(pr_loc)) == os.path.normpath(os.path.realpath(imp_loc)) + and imp_comment == "distribute"): + errors.append("Warning: dependency 'setuptools' found to be version %s of 'distribute' from %r " + "by pkg_resources, but 'import setuptools' gave version %s [%s] from %r.
