In [4965/ticket1306]:

src/allmydata/_auto_deps.py: Fix 'DeprecationWarning?: the sets module is deprecated'. refs #1329

[warner]

I just released foolscap-0.6.1, which removes the offending import sets, so this ticket can be resolved by increasing Tahoe's requirement to foolscap-0.6.1 .

[zooko]

-0 from me -- I would rather suppress the warning the way [20110116200112-93fa1-0397f85493a9fd0ae82ce58d7291d598a4f6e2d6]/ticket1306 attempts to do or change the test to tolerate the noise than raise the dependency requirement. But, it is just a -0. If you prefer it, go ahead.

[warner]

my main problem with [20110116200112-93fa1-0397f85493a9fd0ae82ce58d7291d598a4f6e2d6]/ticket1306 is that it involved what looked like a signficant refactoring of _auto_deps.py, so I couldn't apply just a single patch (there were more like six). But if there's a clean way to use that approach, I'm happy to go with it.

The clock is ticking, though :)

[zooko]

Replying to warner:

my main problem with [20110116200112-93fa1-0397f85493a9fd0ae82ce58d7291d598a4f6e2d6]/ticket1306 is that it involved what looked like a signficant refactoring of _auto_deps.py, so I couldn't apply just a single patch (there were more like six). But if there's a clean way to use that approach, I'm happy to go with it.

For the record, here are the patches that (from darcs's perspective) are required for [20110116200112-93fa1-0397f85493a9fd0ae82ce58d7291d598a4f6e2d6]/ticket1306:

Sat Jan  1 04:01:41 MST 2011  david-sarah@jacaranda.org
  * allmydata/__init__.py: don't use pkg_resources.require to get versions and paths. Also change pyOpenSSL to pyopenssl since that is the package name. fixes #1287
Shall I push this patch? (1/7)  [ynWsfvplxdaqjk], or ? for help: w
Sat Jan  1 13:05:02 MST 2011  david-sarah@jacaranda.org
  * allmydata/_auto_deps.py: add a comment reminding to change __init__.py when dependencies are added or removed. Clarify a comment in __init__.py. refs #1287
Shall I push this patch? (2/7)  [ynWvplxdaqjk], or ? for help: w
Sat Jan  1 12:25:59 MST 2011  david-sarah@jacaranda.org
  * test_runner: add test_import_in_repl, which uses 'bin/tahoe debug repl' to import the allmydata module and checks that it comes from the right path. Also, fix a latent bug that caused test_the_right_code to incorrectly conclude that a path mismatch was due to a Unicode path (causing a skip rather than a failure). This version of the patch avoids a confusing shadowing of 'srcfile'. refs #1258
Shall I push this patch? (3/7)  [ynWsfvplxdaqjk], or ? for help: w
Wed Jan 12 21:24:57 MST 2011  david-sarah@jacaranda.org
  * Make bb-freeze work. This also implements more robust checking of dependency requirements, as discussed in ticket:585#comment:10 . refs #585
Shall I push this patch? (4/7)  [ynWvplxdaqjk], or ? for help: w
Wed Jan 12 21:30:40 MST 2011  david-sarah@jacaranda.org
  * Move get_package_versions_and_locations from __init__.py to _auto_deps.py (because it needs to be updated when dependencies change). refs #585
Shall I push this patch? (5/7)  [ynWvplxdaqjk], or ? for help: w
Fri Jan 14 22:02:45 MST 2011  david-sarah@jacaranda.org

And below and attached is the unified diff of all seven of them coalesced.

I propose that we start by applying the first one -- see #1258.
