From: Brian Warner Date: Sun, 24 Jun 2012 19:10:24 +0000 (-0700) Subject: _auto_deps: bump foolscap to >=0.6.3 to tolerate twisted-12.0.0 X-Git-Url: https://git.rkrishnan.org/?a=commitdiff_plain;h=69bd49fc57bf9e6f851c8f68458d6f518d2c8c2e;p=tahoe-lafs%2Ftahoe-lafs.git _auto_deps: bump foolscap to >=0.6.3 to tolerate twisted-12.0.0 The current Twisted release is 12.1.0, which (like 12.0.0 before it) isn't compatible with foolscap-0.6.2 and earlier. We previously required foolscap>=0.6.1, since that's all we actually need from foolscap itself. _auto_deps specifies twisted>=11.0.0, so any system that can't meet that will install the current Twisted (12.1.0), which will give them something incompatible with foolscap-0.6.1 and 0.6.2 . If we're limited to setuptools's declarative constraint language (and can't have a function which evaluates the available dependency versions and gives recommendations on which to change), then the only safe approach is to make sure that any acceptable Foolscap version will be compatible with all acceptable Twisted versions. So, bump the foolscap dependency to >=0.6.3, which covers all currently-known incompatibilities. --- diff --git a/src/allmydata/_auto_deps.py b/src/allmydata/_auto_deps.py index 8dd3898d..7cce8fc1 100644 --- a/src/allmydata/_auto_deps.py +++ b/src/allmydata/_auto_deps.py @@ -17,31 +17,36 @@ install_requires = [ # zope.interface 3.6.3 and 3.6.4 are incompatible with Nevow (#1435).
