Kevan Carstensen **20110830210141 Ignore-this: fceafbe485851ca53f2774e5a4fd8d30 Note that the downloader will still fetch a segment for a zero-length read, which is wasteful. Fixing that isn't specifically required to fix #1512, but it should probably be fixed before 1.9. ] [NEWS: added summary of all changes since 1.8.2. Needs editing.

It also fixes a couple of places where a Deferred was being dropped, which would cause two tests to run in parallel and also confuse error reporting. ] [Let Uploader retain History instead of passing it into upload().

Previously, certain webapi upload operations (like PUT /uri/$DIRCAP/newchildname) failed to pass the History object and were left out. ] [Fix mutable publish/retrieve timing status displays.

Brian Warner **20110828232221 Ignore-this: 4080ce065cf481b2180fd711c9772dd6 publish: * encrypt and encode times are cumulative, not just current-segment retrieve: * same for decrypt and decode times * update "current status" to include segment number * set status to Finished/Failed when download is complete * set progress to 1.0 when complete More improvements to consider: * progress is currently 0% or 100%: should calculate how many segments are involved (remembering retrieve can be less than the whole file) and set it to a fraction * "fetch" time is fuzzy: what we want is to know how much of the delay is not our own fault, but since we do decode/decrypt work while waiting for more shares, it's not straightforward ] [Teach 'tahoe debug catalog-shares about MDMF.

The new code always uses [k,segsize]. ] [layout.py: fix MDMF share layout documentation Brian Warner **20110828073921 Ignore-this: 3f13366fed75b5e31b51ae895450a225 ] [teach 'tahoe debug dump-share' about MDMF and offsets. refs #1507 Brian Warner **20110828073834 Ignore-this: 3a9d2ef9c47a72bf1506ba41199a1dea ] [test_mutable.Version.test_debug: use splitlines() to fix buildslaves Brian Warner **20110828064728 Ignore-this: c7f6245426fc80b9d1ae901d5218246a Any slave running in a directory with spaces in the name was miscounting shares, causing the test to fail. ] [test_mutable.Version: exercise 'tahoe debug find-shares' on MDMF. refs #1507 Brian Warner **20110828005542 Ignore-this: cb20bea1c28bfa50a72317d70e109672 Also changes NoNetworkGrid to put shares in storage/shares/ . ] [test_mutable.py: oops, missed a .todo Brian Warner **20110828002118 Ignore-this: fda09ae86481352b7a627c278d2a3940 ] [test_mutable: merge davidsarah's patch with my Version refactorings warner@lothar.com**20110827235707 Ignore-this: b5aaf481c90d99e33827273b5d118fd0 ] [Make the immutable/read-only constraint checking for MDMF URIs identical to that for SSK URIs. refs #393 david-sarah@jacaranda.org**20110823012720 Ignore-this: e1f59d7ff2007c81dbef2aeb14abd721 ] [Additional tests for MDMF URIs and for zero-length files. refs #393 david-sarah@jacaranda.org**20110823011532 Ignore-this: a7cc0c09d1d2d72413f9cd227c47a9d5 ] [Additional tests for zero-length partial reads and updates to mutable versions. refs #393 david-sarah@jacaranda.org**20110822014111 Ignore-this: 5fc6f4d06e11910124e4a277ec8a43ea ] [test_mutable.Version: factor out some expensive uploads, save 25% runtime Brian Warner **20110827232737 Ignore-this: ea37383eb85ea0894b254fe4dfb45544 ] [SDMF: update filenode with correct k/N after Retrieve. Fixes #1510. Brian Warner **20110827225031 Ignore-this: b50ae6e1045818c400079f118b4ef48 Without this, we get a regression when modifying a mutable file that was created with more shares (larger N) than our current tahoe.cfg . The modification attempt creates new versions of the (0,1,..,newN-1) shares, but leaves the old versions of the (newN,..,oldN-1) shares alone (and throws a assertion error in SDMFSlotWriteProxy.finish_publishing in the process). The mixed versions that result (some shares with e.g. N=10, some with N=20, such that both versions are recoverable) cause problems for the Publish code, even before MDMF landed. Might be related to refs #1390 and refs #1042. ] [layout.py: annotate assertion to figure out 'tahoe backup' failure Brian Warner **20110827195253 Ignore-this: 9b92b954e3ed0d0f80154fff1ff674e5 ] [Add 'tahoe debug dump-cap' support for MDMF, DIR2-CHK, DIR2-MDMF. refs #1507.
