From: Brian Warner Date: Sat, 27 Aug 2011 19:50:48 +0000 (-0700) Subject: Add 'tahoe debug dump-cap' support for MDMF, DIR2-CHK, DIR2-MDMF. refs #1507. X-Git-Url: https://git.rkrishnan.org/vdrive/nxhtml.html?a=commitdiff_plain;h=482a7dd3f11a19d0fc6e22524736f744deb1ce88;p=tahoe-lafs%2Ftahoe-lafs.git Add 'tahoe debug dump-cap' support for MDMF, DIR2-CHK, DIR2-MDMF. refs #1507. This also adds tests for all those cases, and fixes an omission in uri.py that broke parsing of DIR2-MDMF-Verifier and DIR2-CHK-Verifier. --- diff --git a/src/allmydata/scripts/debug.py
