Nuts and Bolts

Nuts and Bolts is held regularly at 1700Z on Tuesdays and Fridays. You can attend the Hangout at the following Hangout URL.

Friday, 01/29/16

Attendees: Brian Warner, David Stainton, Leif Ryge, meejah, Patrick R McDonald, Zooko Wilcox

There was a large amount of discussion centered tradeoffs between reliability/availability vs the ability to revoke or unshare something. Leif and David brought up the excellent point that once you provide another person which a cap, you currently do not have a reliable method to revoke access to the data associated with that cap. This may be one of the reasons for the slowness in Tahoe-LAFS' adoption. Users have trouble understanding that access controls in Tahoe-LAFS are not handled by a third party to allow for easy revocation.

Tuesday, 02/02/16

Attendees: Brian Warner, Chris Wood, Daira Hopwood, David Stainton, Leif Ryge, meejah, Patrick R McDonald, Zooko Wilcox

Account creation on Tahoe Trac is resolved thanks to Brian. Hopefully it will remain resistant to spammers for awhile.

Zooko will merge github.com/zooko/pycryptopp master and github.com/tahoe-lafs/pycryptopp master and version and tag it as 0.7.1

A large amount of time was spent on ticket triage. Below are the results of the triage.

  • #2534 - The problem will be resolved by either an upgrade of Foolscap or an upgrade to Tahoe-LAFS 1.10.3. Brian will the latest Foolscap a dependency (#2722) of Tahoe-LAFS.
  • #1949 and #2137 appear to have the same underlying cause
  • #2543 - To be resolved for 1.10.3
  • #2709 - Moved out of the release
  • #517, #1007 and #1010 - Are moved to the 1.11.0
  • #1349 - Brian and Leif will work to resolve this
  • #2045 - Adding 1.11

After the meeting, Daira fixed #2724, #1949, #2137, and #2543.

The buildbot is mostly red right now. The failures (and steps-to-resolve) are:

  • "Daira Win7-64": failing tests because of windows lacking time.tzset, Daira is investigating
  • "FreeStorm CentOS6": using py2.6 (no longer supported), Brian will remove
  • "MM netbsd5": using py2.6, Brian will remove
  • "Marcus Cygwin WinXP": using py2.6, Brian will remove
  • "Ubuntu trusty 14.04": cffi version mismatch, Daira might spin up VM to reproduce
  • "clean", "memcheck-32": same (runs on same vm)
  • "Warner OS-X 10.11": current pycryptopp won't compile, Zooko will make new release of pycryptopp to fix
  • "memcheck-64": build fails, looking for obsolete distribution "twisted-web", Brian will investigate * known bug in recent Debian packaging: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=811392

After the meeting, the following updates were made:

  • py2.6 builders removed
  • cffi mismatch resolved (added a virtualenv to isolate tahoe tests from host packages)
  • memcheck-64 Debian bug fixed, waiting for new package to appear on mirrors, should be installed on 02/04/2016
