2  * immutable: download from the first servers which provide at least K buckets instead of waiting for all servers to reply
3  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.

343 
344 Mutable servermap updates and the immutable checker, when run with
345 add_lease=True, send both the do-you-have-block and add-lease commands in
346 parallel, to avoid an extra round trip time. Many older servers have problems
347 with add-lease and raise various exceptions, which don't generally matter.
348 The client-side code was catching+ignoring some of them, but unrecognized
349 exceptions were passed through to the DYHB code, concealing the DYHB results
350 from the checker, making it think the server had no shares.
351 
352 The fix is to separate the code paths. Both commands are sent at the same
353 time, but the errback path from add-lease is handled separately. Known
354 exceptions are ignored, the others (both unknown-remote and all-local) are
355 logged (log.WEIRD, which will trigger an Incident), but neither will affect

405 The webapi has been looking for an Accept header since 1.4.0, but it treats a
406 missing header as equal to */* (to honor RFC2616). This change finally
407 modifies our CLI tools to ask for "text/plain, application/octet-stream",
408 which seems roughly correct (we either want a plain-text traceback or error
409 message, or an uninterpreted chunk of binary data to save to disk). Some day
410 we'll figure out how JSON fits into this scheme.

854 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...
