197 This can be useful if one of the ones that he has already begun downloading fails. See #287 for discussion. This fixes part of #287 which part was a regression caused by #928, namely this fixes fail-over in case a share is corrupted (or the server returns an error or disconnects). This does not fix the related issue mentioned in #287 if a server hangs and doesn't reply to requests for blocks.

243 Ignore-this: c855355a40d96827e1d0c469a8d8ab3f
244 This should put an end to the phenomenon I've been seeing that a single hung server can cause all downloads on a grid to hang.  Also it should speed up all downloads by (a) not-waiting for responses to queries that it doesn't need, and (b) downloading shares from the servers which answered the initial query the fastest.
245 Also, do not count how many buckets you've gotten when deciding whether the download has enough shares or not -- instead count how many buckets to *unique* shares that you've gotten.  This appears to improve a slightly weird behavior in the current download code in which receiving >= K different buckets all to the same sharenumber would make it think it had enough to download the file when in fact it hadn't.
246 This patch needs tests before it is actually ready for trunk.

553 Ignore-this: ef1a367b93e4d01298c2b1e6ca59c492
554 
555 Mutable servermap updates and the immutable checker, when run with
556 add_lease=True, send both the do-you-have-block and add-lease commands in
557 parallel, to avoid an extra round trip time. Many older servers have problems
558 with add-lease and raise various exceptions, which don't generally matter.
559 The client-side code was catching+ignoring some of them, but unrecognized
560 exceptions were passed through to the DYHB code, concealing the DYHB results
561 from the checker, making it think the server had no shares.
562 
563 The fix is to separate the code paths. Both commands are sent at the same
564 time, but the errback path from add-lease is handled separately. Known
565 exceptions are ignored, the others (both unknown-remote and all-local) are
566 logged (log.WEIRD, which will trigger an Incident), but neither will affect
567 the DYHB results.
568 
569 The add-lease message is sent first, and we know that the server handles them
570 synchronously. So when the checker is done, we can be sure that all the
571 add-lease messages have been retired. This makes life easier for unit tests.

616 The webapi has been looking for an Accept header since 1.4.0, but it treats a

618 modifies our CLI tools to ask for "text/plain, application/octet-stream",
619 which seems roughly correct (we either want a plain-text traceback or error
620 message, or an uninterpreted chunk of binary data to save to disk). Some day
621 we'll figure out how JSON fits into this scheme.

1057[setup: remove a convenience copy of figleaf, to ease inclusion into Ubuntu Karmic Koala
1058zooko@zooko.com**20090924053215

1060 We need to carefully document the licence of figleaf in order to get Tahoe-LAFS into Ubuntu Karmic Koala.  However, figleaf isn't really a part of Tahoe-LAFS per se -- this is just a "convenience copy" of a development tool.  The quickest way to make Tahoe-LAFS acceptable for Karmic then, is to remove figleaf from the Tahoe-LAFS tarball itself.  People who want to run figleaf on Tahoe-LAFS (as everyone should want) can install figleaf themselves.  I haven't tested this -- there may be incompatibilities between upstream figleaf and the copy that we had here...

(Nattraverso was not assigned to allmydata.com -- it was LGPL'ed -- but I checked and src/allmydata/util/iputil.py was completely rewritten and doesn't contain any line of code from nattraverso.)  Add notes to misc/debian/copyright about licensing on files that aren't just allmydata.com-licensed.

1108 That version of darcsver emits a scary error message when the darcs executable or the _darcs subdirectory is not found.
1109 This error is hidden (unless the --loud option is passed) in darcsver >= 1.3.1.
1110 Fixes #788.

1115 This makes it more obvious that the Helper currently generates leases with
1116 the Helper's own secrets, rather than getting values from the client, which
1117 is arguably a bug that will likely be resolved with the Accounting project.
