[* fuse/runtests: added --catch-up-pause option
robk-tahoe@allmydata.com**20081021002902
 
 On linux, write tests are failing because data written to fuse isn't showing
 up in tahoe by the time it's checked.  it's not clear where this is originating,
 since the fuse implementation [should be] waiting for completion of tahoe 
 operations before returning from its calls.  This adds an option to control the
 duration of a pause between the fuse write and the check of tahoe, which is by
 default set to 2s on linux, which - somewhat inexplicably - seems to 'fix' the 
 problem, in as far as it allows tests to complete.

[fuse/blackmatch: added asynchronous (background) file download
robk-tahoe@allmydata.com**20081020233333
 
 previously, upon opening a file for reading, the open() call would block
 while the entire file was retrieved from tahoe into the cache directory.
 This change adds a DownloaderWithReadQueue class, and associated plumbing,
 such that an open() will return promptly with the download initiated 'in
 the background'.  Subsequent read() operations will block until enough
 data has been downloaded to satisfy that request.  This provides a behaviour
 similar to streaming, i.e. the client application will be able to read
 data from the fuse interface while the remainder of the file is still being
 downloaded.
 
] 
[fuse/runtests: added 'read_in_random_order' test
robk-tahoe@allmydata.com**20081020232427
 
 this test uploads a test file to tahoe, and then reads the file from fuse,
 but reads the blocks of the file in a random order; this is designed to
 exercise the asynchronous download feature of blackmatch - where the file
 is downloaded from tahoe asynchronously, and rather than blocking open()
 for the entirety of the download, instead individual read() calls are
 blocked until enough of the file has been downloaded to satisfy them
] 
[fuse/runtests: added a --no-cleanup option
robk-tahoe@allmydata.com**20081020155120
 
 the code had a 'fullcleanup' flag internally which controlled whether
 working directories were cleaned up.  this promotes that to a command
 line option (negated) '--no-cleanup' defaulting to False, i.e. do cleanup

 of a test failure, but rather just dumps the start/end of the errant strings

[fuse/blackmatch: fix platform specific problems in repr_flags
robk-tahoe@allmydata.com**20081020143052
 
 the repr_flags debug/logging function had a list of fields from the os 
 module that might be passed into an open() call, but it included at 
 least one which was available on the mac but not on linux. symmetrically
 linux has numerous flags which are not present on the mac. the repr_flags
 function is now tolerant of flags not being present, and has an expanded
 list of flags

[makefile: added 'fuse-test' target to makefile, to run 'runtests'

[fuse/runtests: added a 'todo' flag, surpressing failure for implementations not expected to pass
robk-tahoe@allmydata.com**20081019131600
 
 since the current tests assume that the implementation responds to changes made
 to tahoe after mount, and impl_b prefetches and cached directory data, impl_b
 fails the current 'read' test suite.
 
 rather than reflect that problem in the overall failure of the runtests exit
 code, this adds a 'todo' flag to the implementations table, and sets the todo
 flag for impl_b.  Thus errors will therein be reported in output, but not cause
 a failing exit code.

robk-tahoe@allmydata.com**20081017030154

[fuse/blackmatch: update json handling to support simplejson v2
robk-tahoe@allmydata.com**20081017025931
 
 simplejson v2 returns strings as either unicode or str, depending upon its
 mood.  thus the interpretation of the node's json repr of a directory, and
 the serialisation of strings in the json based rpc both exploded when built
 against simplejson v2.  this makes both of these places liberal in their
 acceptance of either str or unicode.

] 
[fuse/blackmatch: add readability to some logging, fix a permissions problem
robk-tahoe@allmydata.com**20081017004421
 
 adds a couple of functions to unpack 'mode' and 'flags' for open() calls, to
 facilitate debugging.
 
 adds a fix to ensure that all tmp files created for writing are opened with
 permissions 0600 - one problem I had with testing with the Finder was that
 files were being opened write only (0200) and were then failing to upload
 to tahoe due to internal permission denied errors.
 
 there remain a variety of problems with finder access which I'm unable to
 comprehend at this time.  sometimes copies to tahoe will work fine, sometimes
 they yield "the finder cannot complete the operation because some data ...
 could not be read or written. (Error code -36)" sometimes "You may need to
 enter the name and password for an administrator on this computer to change
 the item" sometimes "The operation cannot be completed because an item with
 the name ... already exists." and sometimes "The operation cannot be completed
 because the item ... is locked."  What seems to be absent is rhyme or reason.
 
 unix operations (cp, mv) work fine, rsync works fine.

[fuse/blackmatch: fix linkage problems with daemonize
robk-tahoe@allmydata.com**20081016163637
 
 the daemonize() function imported from twisted was causing problems when 
 run from a frozen (py2app) build.  I simply copied the daemonize function
 into this file, and that fixes the problem.
 
 also removed a couple of lines of debugging spam that slipped through.

 bumped the delay between mounting a filesystem and 'open'ing it in Finder to
 4s, as it seems to take a little longer to mount now the client and server
 fuse processes need to coordinate.
] 
[fuse/blackmatch: split into client/server (twisted server)
robk-tahoe@allmydata.com**20081016150846
 
 This implements a client/server split for blackmatch, where the client 
 implements the fuse_main bindings and a simple blocking rpc client mechanism.
 The server implements the other half of that rpc mechanism, and contains all
 the actual logic for interpreting fuse requests in the context of the on disk
 cache and requests to the tahoe node.  The server is based on a twisted reactor.
 
 The rpc mechanism implements a simple method dispatch including marshalling,
 using json, of basic inert data types, in a flat namespace (no objects).
 The client side is written in a blocking idiom, to interface with the threading
 model used by the fuse_main bindings, whereas the server side is written for a
 twisted reactor-based environment, intended to facilitate implementing more 
 sophisticated logic in that paradigm.  The two communicate over a unix domain
 socket, allocated within the nodedir.
 
 Command line usage is unchanged; the server is launched automatically by the
 client. The server daemonizes itself, to avoid preventing the original parent
 process (e.g. 'runtests') from waiting upon the server exiting.
 
 The client keeps open a 'keepalive' connection to the server; upon loss thereof
 the server will exit. This addresses the fact that the python-fuse bindings 
 provide no notification of exit of the client process upon unmount.
 
 The client thus provides a relatively thin 'shim' proxying requests from the
 fuse_main bindings across the rpc to the server process, which handles the 
 logic behind each request.  
 
 For the time being, a '--no-split' option is provided to surpress the splitting
 into client/server, yielding the prior behaviour.  Once the server logic gets
 more complex and more entrenched in a twisted idiom, this might be removed.
 The 'runtests' test harness currently tests both modes, as 'impl_c' and 
 'impl_c_no_split'
 
] 
[fuse/blackmatch: 'flatten' the fuse api implementation
robk-tahoe@allmydata.com**20081016143547
 
 the previous revision of blackmatch used a file_class to delegate all fuse
 api operations on files to a specific per-file class, which is an option
 given by the python-fuse bindings.
 
 this is a pre-cursor to the 'split' client/server version, which uses a
 simple, moreover flat, rpc mechanism to broker access to methods.

[fuse/runtests: disable impl_a/impl_b on mac, as they don't actually work.
robk-tahoe@allmydata.com**20081016143232] 
[fuse/runtests: added write_partial_overwrite test
robk-tahoe@allmydata.com**20081016142926
 
 this tests opening a file for update, overwriting a small part of it, and
 ensuring that the end result constitutes an overwrite of the original file.
 This tests, e.g. the implementation doesn' open a 'fresh' file but does in
 fact initialise the file to be uploaded with the contents of any extant
 file before applying updates
 
] 
[fuse/runtests: added --tests, renamed --suites
robk-tahoe@allmydata.com**20081016142836
 
 changed the --tests option to be --suites, as it takes a prefix, e.g. 'read'
 'write' (or 'all', the default) and runs those suites which are applicable to
 each implementation being tested.
 
 added a --tests option, which takes a list of tests, e.g. 'read_file_contents'
 'write_overlapping_large_writes' and runs all tests specified without regard
 to whether the implementation(s) under test are declared to support them.
 
 this is basically to allow a specific test or two to be run, saving time 
 during development and debugging by not running the entire suite
] 
[fuse/runtests: added 'random scatter' write test
robk-tahoe@allmydata.com**20081003233436
 
 this writes the test file in a randomised order, with randomly sized writes.
 also for each 'slice' of the file written, a randomly chosen overlapping
 write is also made to the file.  this ensures that the file will be written
 in its entirety in a thoroughly random order, with many overlapping writes.
] 
[fuse/runtests: add overlapping write tests
robk-tahoe@allmydata.com**20081003224833
 
 using both small and large blocksizes for writes, write a 1Mb file to fuse
 where every write overlaps another. 
 
 This serves a useful purpose - in manual testing of blackmatch some time ago
 most operations e.g. bulk copies, worked fine, but using rsync caused data 
 corruption on most files.  it turned out to be that rsync writes in 64K blocks,
 but rather than making the last block short, the last block instead overlaps
 the preceding (already written) block.  This revealed a problem where cache
 files were being opened 'append' rather than 'write' and hence the overlapping
 write to the fuse layer caused the overlapping portion of the file to be 
 duplicated in cache, leading to oversized and corrupt files being uploaded.

[fuse/runtests: remove write small file test, as it's subsumed by the tiny_file test
robk-tahoe@allmydata.com**20081003223944] 
[fuse/runtests: added linear write tests for various block sizes
robk-tahoe@allmydata.com**20081003223550
 
 unit tests to test writing contiguous blocks linearly through the file,
 for a variety of block sizes;  'tiny_file' is an entire file fitting within
 a single io block / write operation.  'linear_{small,large}_writes' test
 a 1Mb file written with each write operation containing significantly less
 or more, respecitvely, data than fuse will pass into the implementation as
 a single operation (which on the mac at least is 64Kib)
] 
[fuse/runtests: add a very simple 'write' test
robk-tahoe@allmydata.com**20081003172044
 
 this performs a very simple write through the fuse layer and confirms that
 the file is stored correctly into the tahoe mesh.  ('simple' in the sense
 that the entire file body fits trivially in a single write() operation, 
 disk block etc)
] 
[fuse/runtests: added a --web-open option
robk-tahoe@allmydata.com**20081003172026
 
 similar to the --debug-wait option which causes the test harness to
 pause at various stages of the process to facilitate debugging, this
 option simplifies that debugging by automatically opening a web browser
 to the root dir of that implementation's tests when tests are commenced.
 
 in addition, if --web-open is specfied but --debug-wait is not, the
 harness will still pause after running tests but before tearing down
 the tahoe grid - this allows all tests to run to completion, but
 provide a debugging hook to investigate the end state of the grid's
 contents thereafter.
] 
[fuse/impl_a: fix a suspected bug in caching
robk-tahoe@allmydata.com**20081003171309
 
 from my examination of the tahoe_fuse ('impl_a') code, it looks like 
 the intention is to cache the file contents in memory while it's open,
 since it does in fact do that.  however it looks like it also ignored
 that cache entirely, and made an individual tahoe webapi GET request
 for each and every read() operation regardless of the relative size of
 the read block and the file in question.
 
 this changes that to make read() use the data in memory rather than
 fetch the data over again.   if there's something more subtle going
 on, please let me know.

 a handful of code cleanup, renaming and refactoring.  basically consolidating
 'application logic' (mount/unmount fs) into the 'MacGuiApp' class (the wx.App)
 and cleaning up various scoping things around that.  renamed all references to
 'app' to refer more clearly to the 'AppContainer' or to the guiapp.
 
 globally renamed basedir -> nodedir
 
 also made the guiapp keep a note of each filesystem it mounts, and unmount
 them upon 'quit' so as to cleanup the user's environment before the tahoe node
 vanishes from out underneath the orphaned tahoe fuse processes
 
] 
[gui/macapp: make submenu of aliases for 'webopen'
robk-tahoe@allmydata.com**20080925163919
 
 this changes the 'open webroot' menu item to be a submenu listing all aliases
 defined in ~/.tahoe.  Note that the dock menu does not support submenus, so it
 only offers a single 'open webroot' option for the default tahoe: alias.
 
 I had trouble with this at first and concluded that the submenus didn't work,
 and made it a distinct 'WebUI' menu in it's own right.  on further inspection,
 there are still problems but they seem to be something like once the dock menu
 has been used, sometimes the app's main menubar menus will cease to function,
 and this happens regardless of whether submenus or plain simple menus are used.
 I have no idea what the peoblem is, but it's not submenu specific.

 imposes limits on legitimate users which we don't necessarily want to impose.

[gui/macapp: rough cut of ui tweaks; configurability, auto-mount
robk-tahoe@allmydata.com**20080925141224
 
 chatting with peter, two things the mac gui needed were the ability to mount
 the 'allmydata drive' automatically upon launching the app, and open the
 Finder to reveal it.  (also a request to hide the debug 'open webroot' stuff)
 
 this (somewhat rough) patch implements all the above as default behaviour
 
 it also contains a quick configuration mechanism for the gui - rather than a 
 preferences gui, running with a more 'tahoe' styled mechanism, the contents
 of a few optional files can modify the default behaviour, specifically file
 in ~/.tahoe/gui.conf control behaviour as follows:
 
 auto-mount (bool): if set (the default) then the mac app will, upon launch
 automatically mount the 'tahoe:' alias with the display name 'Allmydata'
 using a mountpoint of ~/.tahoe/mnt/__auto__
 
 auto-open (bool): if set (the default) then upon mounting a file system
 (including the auto-mount if set) finder will be opened to the mountpoint
 of the filesystem, which essentially reveals the newly mounted drive in a
 Finder window
 
 show-webopen (bool): if set (false by default) then the 'open webroot'
 action will be made available in both the dock and file menus of the app 
 
 daemon-timout (int): sets the daemon-timeout option passed into tahoe fuse
 when a filesystem is mounted. this defaults to 5 min
 
 files of type (int) much, naturally contain a parsable int representation.
 files of type (bool) are considered true if their (case-insensitive) contents
 are any of ['y', 'yes', 'true', 'on', '1'] and considered false otherwise.

[fuse/impl_c: UNDO --auto-fsid option
robk-tahoe@allmydata.com**20080925134730
 
 rolling back:
 
 Thu Sep 25 14:42:23 BST 2008  robk-tahoe@allmydata.com
   * fuse/impl_c: add --auto-fsid option
   
   this was inspired by reading the fuse docs and discovering the 'fsid' option
   to fuse_main, and was _intended_ to support a sort of 'stability' to the 
   filesystem (specifically derived from the root-uri mounted, whether directly
   or via an alias) to support mac aliases across unmount/remount etc.
   
   some experimentation shows that that doesn't actually work, and that, at
   least for mac aliases in my testing, they're tied to path-to-mountpoint and
   not to the fsid - which seems to have no bearing.  perhaps the 'local' flag
   is causing weirdness therein.
   
   at any rate, I'm recording it simply for posterity, in case it turns out to
   be useful after all somewhere down the road.

[fuse/impl_c: move mac tahoefuse impl out into contrib/fuse
robk-tahoe@allmydata.com**20080925014214
 
 For a variety of reasons, high amongst them the fact that many people 
 interested in fuse support for tahoe seem to have missed its existence,
 the existing fuse implementation for tahoe, previously 'mac/tahoefuse.py'
 has been renamed and moved.
 
 It was suggested that, even though the mac build depends upon it, that
 the mac/tahoefuse implementation be moved into contrib/fuse along with
 the other fuse implementations.  The fact that it's not as extensively
 covered by unit tests as mainline tahoe was given as corroboration.
 
 In a bid to try and stem the confusion inherent in having tahoe_fuse,
 tfuse and tahoefuse jumbled together (not necessarily helped by 
 referring to them as impl_a, b and c respectively) I'm hereby renaming
 tahoefuse as 'blackmatch'  (black match is, per wikipedia "a type of 
 crude fuse" hey, I'm a punny guy)  Maybe one day it'll be promoted to
 be 'quickmatch' instead...
 
 Anyway, this patch moves mac/tahoefuse.py out to contrib/fuse/impl_c/
 as blackmatch.py, and makes appropriate changes to the mac build process
 to transclude blackmatch therein.  this leaves the extant fuse.py and
 fuseparts business in mac/ as-is and doesn't attempt to address such
 issues in contrib/fuse/impl_c.
 
 it is left as an exercise to the reader (or the reader of a message
 to follow) as to how to deal with the 'fuse' python module on the mac.
 
 as of this time, blackmatch should work on both mac and linux, and
 passes the four extant tests in runtests.  (fwiw neither impl_a nor
 impl_b have I managed to get working on the mac yet)
 
 since blackmatch supports a read-write and caching fuse interface to
 tahoe, some write tests obviously need to be added to runtests.

[macapp: changes to support aliases, updated tahoefuse command line options
robk-tahoe@allmydata.com**20080925010128
 
 the tahoefuse command line options changed to support the runtests harness,
 and as part of that gained support for named aliases via --alias
 
 this changes the mac app's invocation of tahoefuse to match that, and also
 changes the gui to present the list of defined aliases as valid mounts
 
 this replaces the previous logic which examined the ~/.tahoe/private directory
 looking for files ending in '.cap' - an ad-hoc alias mechanism.
 
 if a file is found matching ~/.tahoe/private/ALIASNAME.icns then that will still
 be passed to tahoefuse as the icon to display for that filesystem. if no such
 file is found, the allmydata icon will be used by default.
 
 the '-olocal' option is passed to tahoefuse.  this is potentially contentious.
 specifically this is telling the OS that this is a 'local' filesystem, which is
 intended to be used to locally attached devices.  however leopard (OSX 10.5)
 will only display non-local filesystems in the Finder's side bar if they are of
 fs types specifically known by Finder to be network file systems (nfs, cifs, 
 webdav, afp)  hence the -olocal flag is the only way on leopard to cause finder
 to display the mounted filesystem in the sidebar, but it displays as a 'device'.
 there is a potential (i.e. the fuse docs carry warnings) that this may cause
 vague and unspecified undesirable behaviour.

[fuse/impl_c: reworking of mac/tahoefuse, command line options, test integration
robk-tahoe@allmydata.com**20080925001535
 
 a handful of changes to the tahoefuse implementation used by the mac build, to 
 make command line option parsing more flexible and robust, and moreover to 
 facilitate integration of this implementation with the 'runtests' test harness
 used to test the other two implementations.
 
 this patch includes;
 - improvements to command line option parsing [ see below ]
 - support for 'aliases' akin to other tahoe tools
 - tweaks to support linux (ubuntu hardy)
 
 the linux support tweaks are, or at least seem to be, a result of the fact that
 hardy ships with fuse 0.2pre3, as opposed to the fuse0.2 that macfuse is based
 upon.  at least the versions I was working with have discrepencies in their
 interfaces, but on reflection this is probably a 'python-fuse' version issue
 rather than fuse per se.  At any rate, the fixes to handling the Stat objects
 should be safe against either version, it's just that the bindings on hardy
 lacked code that was in the 'fuse' python module on the mac...
 
 command line options:
 
 the need for more flexible invocation in support of the runtests harness led
 me to rework the argument parsing from some simple positional hacks with a
 pass-through of the remainder to the fuse binding's 'fuse_main' to a system
 using twisted.usage to parse arguments, and having just one option '-o' being
 explicitly a pass-through for -o options to fuse_main. the options are now:
 
 --node-directory NODEDIR : this is used to look up the node-url to connect
 to if that's not specified concretely on the command line, and also used to
 determine the location of the cache directory used by the implementation,
 specifically '_cache' within the nodedir.  default value: ~/.tahoe
 
 --node-url NODEURL : specify a node-url taking precendence over that found
 in the node.url file within the nodedir
 
 --alias ALIAS : specifies the named alias should be mounted. a lookup is
 performed in the alias table within 'nodedir' to find the root dir cap
 the named alias must exist in the alias table of the specified nodedir
 
 --root-uri ROOTURI : specifies that the given directory uri should be mounted
 
 at least one of --alias and --root-uri must be given (which directory to mount
 must be specified somehow)  if both are given --alias takes precedence.
 
 --cache-timeout TIMEOUTSECS : specifies the number of seconds that cached
 directory data should be considered valid for.  this tahoefuse implementation
 implements directory caching for a limited time; largely because the mac (i.e.
 the Finder in particular) tends to make a large number of requests in quick 
 successsion when browsing the filesystem.  on the flip side, the 'runtests'
 unit tests fail in the face of such caching because the changes made to the
 underlying tahoe directories are not reflected in the fuse presentation.  by 
 specifying a cache-timeout of 0 seconds, runtests can force the fuse layer
 into refetching directory data upon each request.
 
 any number of -oname=value options may be specified on the command line,
 and they will all be passed into the underlying fuse_main call.
 
 a single non-optional argument, the mountpoint, must also be given.

[fuse/tests: slew of changes to fuse 'runtests'
robk-tahoe@allmydata.com**20080924183601
 
 This patch makes a significant number of changes to the fuse 'runtests' script
 which stem from my efforts to integrate the third fuse implementation into this
 framework.  Perhaps not all were necessary to that end, and I beg nejucomo's
 forebearance if I got too carried away.
 
 - cleaned up the blank lines; imho blank lines should be empty
 
 - made the unmount command switch based on platform, since macfuse just uses
 'umount' not the 'fusermount' command (which doesn't exist)
 
 - made the expected working dir for runtests the contrib/fuse dir, not the 
 top-level tahoe source tree - see also discussion of --path-to-tahoe below
 
 - significantly reworked the ImplProcManager class.  rather than subclassing
 for each fuse implementation to be tested, the new version is based on 
 instantiating objects and providing relevant config info to the constructor.
 this was motivated by a desire to eliminate the duplication of similar but
 subtly different code between instances, framed by consideration of increasing
 the number of platforms and implementations involved. each implementation to
 test is thus reduced to the pertinent import and an entry in the 
 'implementations' table defining how to handle that implementation. this also
 provides a way to specify which sets of tests to run for each implementation,
 more on that below.
 
 
 - significantly reworked the command line options parsing, using twisted.usage;
 
 what used to be a single optional argument is now represented by the 
 --test-type option which allows one to choose between running unittests, the
 system tests, or both.
 
 the --implementations option allows for a specific (comma-separated) list of
 implemenations to be tested, or the default 'all'
 
 the --tests option allows for a specific (comma-separated) list of tests sets
 to be run, or the default 'all'.  note that only the intersection of tests
 requested on the command line and tests relevant to each implementation will
 be run. see below for more on tests sets.
 
 the --path-to-tahoe open allows for the path to the 'tahoe' executable to be
 specified. it defaults to '../../bin/tahoe' which is the location of the tahoe
 script in the source tree relative to the contrib/fuse dir by default.
 
 the --tmp-dir option controls where temporary directories (and hence 
 mountpoints) are created during the test.  this defaults to /tmp - a change
 from the previous behaviour of using the system default dir for calls to 
 tempfile.mkdtemp(), a behaviour which can be obtained by providing an empty
 value, e.g. "--tmp-dir=" 
 
 the --debug-wait flag causes the test runner to pause waiting upon user
 input at various stages through the testing, which facilitates debugging e.g.
 by allowing the user to open a browser and explore or modify the contents of
 the ephemeral grid after it has been instantiated but before tests are run,
 or make environmental adjustments before actually triggering fuse mounts etc.
 note that the webapi url for the first client node is printed out upon its
 startup to facilitate this sort of debugging also.
 
 
 - the default tmp dir was changed, and made configurable. previously the 
 default behaviour of tempfile.mkdtemp() was used.  it turns out that, at least
 on the mac, that led to temporary directories to be created in a location
 which ultimately led to mountpoint paths longer than could be handled by 
 macfuse - specifically mounted filesystems could not be unmounted and would
 'leak'. by changing the default location to be rooted at /tmp this leads to
 mountpoint paths short enough to be supported without problems.
 
 - tests are now grouped into 'sets' by method name prefix.  all the existing
 tests have been moved into the 'read' set, i.e. with method names starting
 'test_read_'. this is intended to facilitate the fact that some implementations
 are read-only, and some support write, so the applicability of tests will vary
 by implementation. the 'implementations' table, which governs the configuration
 of the ImplProcManager responsible for a given implementation, provides a list
 of 'test' (i.e test set names) which are applicable to that implementation.
 note no 'write' tests yet exist, this is merely laying the groundwork.
 
 - the 'expected output' of the tahoe command, which is checked for 'surprising'
 output by regex match, can be confused by spurious output from libraries.
 specfically, testing on the mac produced a warning message about zope interface
 resolution various multiple eggs.  the 'check_tahoe_output()' function now has
 a list of 'ignorable_lines' (each a regex) which will be discarded before the
 remainder of the output of the tahoe script is matched against expectation.
 
 - cleaned up a typo, and a few spurious imports caught by pyflakes

 specifically change the expectation of the code to be such that the node-url

 moreover read the node-url from the 'node.url' file found in the node 'basedir'
 and only if that doesn't exist, then fall back to reading the 'webport' file
 from therein and assuming localhost.  This then supports the general tahoe 
 pattern that tools needing only a webapi server can be pointed at a directory
 containing the node.url file, which can optionally point to another server,
 rather than requiring a complete node dir and locally running node instance.

[fuse/impl_b: tweaks from testing on hardy
robk-tahoe@allmydata.com**20080924180738
 
 from testing on linux (specifically ubuntu hardy) the libfuse dll has a
 different name, specifically libfuse.so.2. this patch tries libfuse.so
 and then falls back to trying .2 if the former fails.
 
 it also changes the unmount behaviour, to simply return from the handler's
 loop_forever() loop upon being unmounted, rather than raising an EOFError,
 since none of the client code I looked at actually handled that exception,
 but did seem to expect to fall off of main() when loop_forever() returned.
 Additionally, from my testing unmount typically led to an OSError from the
 fuse fd read, rather than an empty read, as the code seemed to expect.
 
 also removed a spurious import pyflakes quibbled about.

[CLI: rework webopen, and moreover its tests w.r.t. path handling
robk-tahoe@allmydata.com**20080924164523
 
 in the recent reconciliation of webopen patches, I wound up adjusting
 webopen to 'pass through' the state of the trailing slash on the given
 argument to the resultant url passed to the browser.  this change 
 removes the requirement that arguments must be directories, and allows
 webopen to be used with files.  it also broke the tests that assumed
 that webopen would always normalise the url to have a trailing slash.
 
 in fixing the tests, I realised that, IMHO, there's something deeply
 awry with the way tahoe handles paths; specifically in the combination
 of '/' being the name of the root path within an alias, but a leading
 slash on paths, e.g. 'alias:/path', is catagorically incorrect. i.e.
  'tahoe:' == 'tahoe:/' == '/' 
 but 'tahoe:/foo' is an invalid path, and must be 'tahoe:foo'
 
 I wound up making the internals of webopen simply spot a 'path' of
 '/' and smash it to '', which 'fixes' webopen to match the behaviour
 of tahoe's path handling elsewhere, but that special case sort of
 points to the weirdness.
 
 (fwiw, I personally found the fact that the leading / in a path was
 disallowed to be weird - I'm just used to seeing paths qualified by
 the leading / I guess - so in a debate about normalising path handling
 I'd vote to include the /)

[rewrite parts of the Makefile in setup.py. Add 'build_tahoe' and 'trial' subcommands.
warner@allmydata.com**20080912010321
 
 The 'make build' target now runs 'setup.py build_tahoe', which figures out
 where the target 'supportlib' directory should go, and invokes 'setup.py
 develop' with the appropriate arguments.
 
 The 'make test' target now runs 'setup.py trial', which manages sys.path and
 runs trial as a subroutine instead of spawning an external process. This
 simplifies the case where Twisted was built as a dependent library (and thus
 the 'trial' executable is not on PATH).
 
 setup.py now manages sys.path and PYTHONPATH for its internal subcommands, so
 the $(PP) prefix was removed from all Makefile targets that invoke setup.py .
 For the remaining ones, the 'setup.py -q show_pythonpath' subcommand was
 added to compute this prefix with python rather than with fragile
 shell/Makefile syntax.

[setup: require secure_connections from foolscap
zooko@zooko.com**20080730021041
 This causes a problem on debian sid, since the pyOpenSSL v0.6 .deb doesn't come
 with .egg-info, so setuptools will not know that it is already installed and
 will try to install pyOpenSSL, and if it installs pyOpenSSL v0.7, then this
 will trigger the bug in Twisted v8.1.0 when used with pyOpenSSL v0.7.
 
 http://twistedmatrix.com/trac/ticket/3218
 
 Now the comments in twisted #3218 suggest that it happens only with the select
 reactor, so maybe using --reactor=poll will avoid it.
