---|
108 | Wed Sep 28 02:38:57 BST 2011 david-sarah@jacaranda.org |
---|
109 | * test_system.py: incorrect arguments were being passed to the constructor for MutableDiskShare. refs #999 |

110 | |
---|
111 | Wed Sep 28 02:40:19 BST 2011 david-sarah@jacaranda.org |

---|
119 | |
---|
120 | Tue Sep 27 08:39:03 BST 2011 david-sarah@jacaranda.org |
---|
121 | * Work in progress for asyncifying the backend interface (necessary to call txaws methods that return Deferreds). This is incomplete so lots of tests fail. refs #999 |
---|
122 | |
---|
123 | Wed Sep 28 06:23:24 BST 2011 david-sarah@jacaranda.org |
---|
124 | * Use factory functions to create share objects rather than their constructors, to allow the factory to return a Deferred. Also change some methods on IShareSet and IStoredShare to return Deferreds. Refactor some constants associated with mutable shares. refs #999 |
---|
125 | |
---|
126 | Thu Sep 29 04:53:41 BST 2011 david-sarah@jacaranda.org |
---|
127 | * Add some debugging code (switched off) to no_network.py. When switched on (PRINT_TRACEBACKS = True), this prints the stack trace associated with the caller of a remote method, mitigating the problem that the traceback normally gets lost at that point. TODO: think of a better way to preserve the traceback that can be enabled by default. refs #999 |
---|
128 | |
---|
129 | Thu Sep 29 04:55:37 BST 2011 david-sarah@jacaranda.org |
---|
130 | * no_network.py: add some assertions that the things we wrap using LocalWrapper are not Deferred (which is not supported and causes hard-to-debug failures). refs #999 |
---|
131 | |
---|
132 | Thu Sep 29 04:56:44 BST 2011 david-sarah@jacaranda.org |
---|
133 | * More asyncification of tests. refs #999 |
---|
134 | |
---|
135 | Thu Sep 29 05:01:36 BST 2011 david-sarah@jacaranda.org |
---|
136 | * Make get_sharesets_for_prefix synchronous for the time being (returning a Deferred breaks crawlers). refs #999 |
---|
137 | |
---|
138 | Thu Sep 29 05:05:39 BST 2011 david-sarah@jacaranda.org |
---|
139 | * scripts/debug.py: take account of some API changes. refs #999 |
---|
140 | |
---|
141 | Thu Sep 29 05:06:57 BST 2011 david-sarah@jacaranda.org |
---|
142 | * Add some debugging assertions that share objects are not Deferred. refs #999 |
---|
143 | |
---|
144 | Thu Sep 29 05:08:00 BST 2011 david-sarah@jacaranda.org |
---|
145 | * Fix some incorrect or incomplete asyncifications. refs #999 |
---|
146 | |
---|
147 | Thu Sep 29 05:11:10 BST 2011 david-sarah@jacaranda.org |
---|
148 | * Comment out an assertion that was causing all mutable tests to fail. THIS IS PROBABLY WRONG. refs #999 |
---|
149 | |
---|
150 | Thu Sep 29 06:50:38 BST 2011 zooko@zooko.com |
---|
151 | * split Immutable S3 Share into for-reading and for-writing classes, remove unused (as far as I can tell) methods, use cStringIO for buffering the writes |
---|
152 | TODO: define the interfaces that the new classes claim to implement |
---|
153 | |
---|
154 | Thu Sep 29 08:55:44 BST 2011 david-sarah@jacaranda.org |
---|
155 | * Complete the splitting of the immutable IStoredShare interface into IShareForReading and IShareForWriting. Also remove the 'load' method from shares, and other minor interface changes. refs #999 |
---|
156 | |
---|
157 | Thu Sep 29 09:05:30 BST 2011 david-sarah@jacaranda.org |
---|
158 | * Add get_s3_share function in place of S3ShareSet._load_shares. refs #999 |
---|
159 | |
---|
160 | Thu Sep 29 09:07:12 BST 2011 david-sarah@jacaranda.org |
---|
161 | * Make the make_bucket_writer method synchronous. refs #999 |
---|
162 | |
---|
163 | Thu Sep 29 09:11:32 BST 2011 david-sarah@jacaranda.org |
---|
164 | * Move the implementation of lease methods to disk_backend.py, and add stub implementations in s3_backend.py that raise NotImplementedError. Fix the lease methods in the disk backend to be synchronous. Also make sure that get_shares() returns a Deferred list sorted by shnum. refs #999 |
---|
165 | |
---|
166 | Thu Sep 29 09:13:31 BST 2011 david-sarah@jacaranda.org |
---|
167 | * test_storage.py: fix an incorrect argument in construction of S3Backend. refs #999 |
---|
168 | |
---|
169 | Thu Sep 29 19:17:54 BST 2011 david-sarah@jacaranda.org |
---|
170 | * Implement selection of backends from tahoe.cfg options. Also remove the discard_storage parameter from the disk backend. refs #999 |
---|
171 | |
---|
172 | Thu Sep 29 19:20:16 BST 2011 david-sarah@jacaranda.org |
---|

7055 | +==================================================== |
---|
7056 | +Storing Shares in Amazon Simple Storage Service (S3) |
---|
7057 | +==================================================== |
---|
7058 | + |
---|
7059 | +S3 is a commercial storage service provided by Amazon, described at |
---|
7060 | +`<https://aws.amazon.com/s3/>`_. |
---|
7061 | + |
---|
7062 | +The Tahoe-LAFS storage server can be configured to store its shares in |
---|
7063 | +an S3 bucket, rather than on local filesystem. To enable this, add the |
---|
7064 | +following keys to the server's ``tahoe.cfg`` file: |
---|
7065 | + |
---|
7066 | +``[storage]`` |
---|
7067 | + |
---|
7068 | +``backend = s3`` |
---|
7069 | + |
---|
7070 | + This turns off the local filesystem backend and enables use of S3. |
---|
7071 | + |
---|
7072 | +``s3.access_key_id = (string, required)`` |
---|
7073 | +``s3.secret_access_key = (string, required)`` |
---|
7074 | + |
---|
7075 | + These two give the storage server permission to access your Amazon |
---|
7076 | + Web Services account, allowing them to upload and download shares |
---|
7077 | + from S3. |
---|
7078 | + |
---|
7079 | +``s3.bucket = (string, required)`` |
---|
7080 | + |
---|
7081 | + This controls which bucket will be used to hold shares. The Tahoe-LAFS |
---|
7082 | + storage server will only modify and access objects in the configured S3 |
---|
7083 | + bucket. |
---|
7084 | + |
---|
7085 | +``s3.url = (URL string, optional)`` |
---|
7086 | + |
---|
7087 | + This URL tells the storage server how to access the S3 service. It |
---|
7088 | + defaults to ``http://s3.amazonaws.com``, but by setting it to something |
---|
7089 | + else, you may be able to use some other S3-like service if it is |
---|
7090 | + sufficiently compatible. |
---|
7091 | + |
---|
7092 | +``s3.max_space = (str, optional)`` |
---|
7093 | + |
---|
7094 | + This tells the server to limit how much space can be used in the S3 |
---|
7095 | + bucket. Before each share is uploaded, the server will ask S3 for the |
---|
7096 | + current bucket usage, and will only accept the share if it does not cause |
---|
7097 | + the usage to grow above this limit. |
---|
7098 | + |
---|
7099 | + The string contains a number, with an optional case-insensitive scale |
---|
7100 | + suffix like "K" or "M" or "G", and an optional "B" or "iB" suffix. So |
---|
7101 | + "100MB", "100M", "100000000B", "100000000", and "100000kb" all mean the |
---|
7102 | + same thing. Likewise, "1MiB", "1024KiB", and "1048576B" all mean the same |
---|
7103 | + thing. |
---|
7104 | + |
---|
7105 | + If ``s3.max_space`` is omitted, the default behavior is to allow |
---|
7106 | + unlimited usage. |
---|
7107 | + |
---|
7108 | + |
---|
7109 | +Once configured, the WUI "storage server" page will provide information about |
---|
7110 | +how much space is being used and how many shares are being stored. |
---|
7111 | + |

7129 | +==================================== |
---|
7130 | +Storing Shares on a Local Filesystem |
---|
7131 | +==================================== |
---|
7132 | + |
---|
7133 | +The "disk" backend stores shares on the local filesystem. Versions of |
---|
7134 | +Tahoe-LAFS <= 1.9.0 always stored shares in this way. |
---|
7135 | + |
---|
7136 | +``[storage]`` |
---|
7137 | + |
---|
7138 | +``backend = disk`` |
---|
7139 | + |
---|
7140 | + This enables use of the disk backend, and is the default. |
---|
7141 | + |
---|
7142 | +``reserved_space = (str, optional)`` |
---|
7143 | + |
---|
7144 | + If provided, this value defines how much disk space is reserved: the |
---|
7145 | + storage server will not accept any share that causes the amount of free |
---|
7146 | + disk space to drop below this value. (The free space is measured by a |
---|
7147 | + call to statvfs(2) on Unix, or GetDiskFreeSpaceEx on Windows, and is the |
---|
7148 | + space available to the user account under which the storage server runs.) |
---|
7149 | + |
---|
7150 | + This string contains a number, with an optional case-insensitive scale |
---|
7151 | + suffix like "K" or "M" or "G", and an optional "B" or "iB" suffix. So |
---|
7152 | + "100MB", "100M", "100000000B", "100000000", and "100000kb" all mean the |
---|
7153 | + same thing. Likewise, "1MiB", "1024KiB", and "1048576B" all mean the same |
---|
7154 | + thing. |
---|
7155 | + |
---|
7156 | + "``tahoe create-node``" generates a tahoe.cfg with |
---|
7157 | + "``reserved_space=1G``", but you may wish to raise, lower, or remove the |
