From 929b49faae23c71f34b397b7c5a9468688e7437a Mon Sep 17 00:00:00 2001 From: Kevin Atkinson Date: Thu, 21 Apr 2016 01:00:00 -0400 Subject: [PATCH 001/195] In the measure package don't return ErrInvalidType in batch Put. None of the other methods in the measure package return this error, instead they only call RecordValue() when the value is []byte. This change makes batch Put consistent with the other methods and allows non []byte data to be passed though the measure datastore.

The datastore has an optional "advanced" datastore that handles Put requests for non []byte values, a "normal" datastore that handles all other put requests, and then any number of other datastore, some of them that can be designated read-only. Delete requests are passed on to all datastore not designed read-only. For now, querying will only work on a "normal" datastore. Note: Only tested in the case of just a "normal" datastore and the case of an "advanced" and "normal" datastore.

From f4ad3babaa3ecbf714e14a153bd1ecf59dcbad23 Mon Sep 17 00:00:00 2001 From: Kevin Atkinson Date: Fri, 6 May 2016 00:53:51 -0400 Subject: [PATCH 004/195] Basic implementation of "add --no-copy". This involved: 1) Maintaing a DataPtr in merkledag.Node and blocks.Block. The DataPtr points to the location of the data within a file on the file system. It the node is a leaf it also contains an alternative serialization of the Node or Block that does not contain the data. 3) A new datastore "filestore" that stores just the information in DataPtr. When retrieving blocks the Merkle-DAG node is reconstructed from combining AltData with the data from the file in the file system. Because the datastore needs to reconstruct the node it needs access to the Protocol Buffers for "merkledag" and "unixfs" and thus, for now, lives in go-ipfs instead of go-datastore. The filestore uses another datastore to store the protocol buffer encoded DataPtr. By default this is the leveldb datastore, as the size for the encoded DataPtr is small.

In DataObj add two fields: the file's modification time, and a flag to mark the content as invalid. If the modification time of the file is the same as the one in the DataObj, skip validation and return the cached value of the invalid flag. If the modification time differs than recheck the hash of the block and update the modification time and invalid flag accordingly. With this change retrieval of blocks from the filestore is as fast as retrieving a block from the normal datastore. Note that when a block is first added the modification time is unset so the first retrial will be slower since the contents need to be verified. After the first retrieval no additional verification needs to be done until the file changed.

In addition to checking if blocks can be read also check for other problems. (1) For each block representing a file root, check that all the blocks in the merkledag tree can be read and the contents of the file can be reconstructed. (2) Check for orphan nodes, those are nodes that are a child of another node that was not found in the filestore. (3) Check if a file was appended too as the block is still valid but no longer represents the contents of the file. The "missing" status, which was used indicate that the file is not found, is now "no-file" and "missing" is now used to indicate when a block could not be found in the datastore. The original verify behavior is still available by using the "--basic" option.

If the pin is a recursive pin that points to a valid block but some of the nodes of the merkle tree are invalid the recursive pin is converted to a direct pin and new recursive pins are created for the nodes that are still valid.

The main use of the datastore is to add content to IPFS +without duplicating the content in the IPFS datastore + +## Quick start + +To add a file to IPFS without copying the contents use `add --no-copy` +or to add a directory use `add -r --no-copy`. (Throughout this +document all command are assumed to start with `ipfs` so `add +--no-copy` really mains `ipfs add --no-copy`) + +Note: For now the daemon running must currently be offline otherwise +you will get an error: `Reader does not support setting ExtraInfo.` + +The file or directory will then be added.

Retrieving blocks from +the filestore takes about the same time when the hash is not +recomputed, when it is retrieval is slower. + +## Verifying blocks + +To list the contents of the filestore use the command `filestore ls`. +See `--help` for additional information. + +Note that due to a known bug, datastore keys are sometimes mangled +(see [go-ipfs issue #2601][1]). Do not be alarmed if you see keys +like `6PKtDkh6GvBeJZ5Zo3v8mtXajfR4s7mgvueESBKTu5RRy`. The block is +still valid and can be retrieved by the unreported correct hash. +(Filestore maintenance operations will still function on the mangled +hash, although operations outside the filestore might complain of an +`invalid ipfs ref path`). + +[1]: https://github.com/ipfs/go-ipfs/issues/2601 + +To verify the contents of the filestore use `filestore verify`. +See `--help` for additional info. + +## Maintenance + +Invalid blocks will cause problems with various parts of ipfs and +should be cleared out on a regular basis. For example, `pin ls` will +currently abort if it is unable to read any blocks pinned (to get +around this use `pin ls -t direct` or `pin ls -r recursive`). Invalid +blocks may cause problems elsewhere. + +Currently no regular maintenance is done and it is unclear if this is +a desirable thing as I image the filestore will primary be used in +conjunction will some higher level tools that will automatically +manage the filestore. + +All maintenance commands should currently be run with the daemon +offline. Running them with the daemon online is untested, in +particular the code has not been properly audited to make sure all the +correct locks are being held. + +## Removing Invalid blocks + +The `filestore clean` command will remove invalid blocks as reported +by `filstore verify`. You must specify what type of invalid blocks to +remove. This command should be used with some care to avoid removing +more than is intended. For help with the command use +`filestore clean --help` + +Removing `changed` and `no-file` blocks (as reported by `filestore verify` +is generally a safe thing to do. When removing `no-file` blocks there +is a slight risk of removing blocks to files that might reappear, for +example, if a filesystem containing the file for the block is not +mounted. + +Removing `error` blocks runs the risk of removing blocks to files that +are not available due to transient or easily correctable (such as +permission problems) errors. + +Removing `incomplete` blocks is generally a good thing to do to avoid +problems with some of the other ipfs maintenance commands such as the +pinner. However, note that there is nothing wrong with the block +itself, so if the missing blocks are still available elsewhere +removing `incomplete` blocks is immature and might lead to lose of +data. + +Removing `orphan` blocks like `incomplete` blocks runs the risk of +data lose if the root node is found elsewhere. Also `orphan` blocks +do not cause any problems, they just take up a small amount of space. + +## Fixing Pins + +When removing blocks `filestore clean` will generally remove any pins +associated with the blocks. However, it will not handle `indirect` +pins. For example if you add a directory using `add -r --no-copy` and +some of the files become invalid the recursive pin will become invalid +and needs to be fixed. + +One way to fix this is to use `filestore fix-pins`. This will +remove any pines pointing to invalid non-existent blocks and also +repair recursive pins by making the recursive pin a direct pin and +pinning any children still valid. + +Pinning the original root as a direct pin may not always be the most +desirable thing to do, in which case you can use the `--skip-root` +to unpin the root, but still pin any children still valid. + +## Pinning and removing blocks manually. + +The desirable behavior of pinning and garbage collection with +filestore blocks is unclear. For now filestore blocks are pinned as +normal when added, but unpinned blocks are not garbage collected and +need to be manually removed. + +To list any unpinned objects in the filestore use `filestore +unpinned`. This command will list unpinned blocks corresponding to +whole files. You can either pin them by piping the output into `pin +add` or manually delete them. + +To manually remove blocks use `filestore rm`. By default only blocks +representing whole files can be removed and the removal will be +recursive. Direct and recursive pins will be removed along with the +block but `filestore rm` will abort if any indirect pins are detected. +To allow the removal of files with indirect pins use the `--force` +option. Individual blocks can be removed with the `--direct` option. + +## Duplicate blocks. + +If a block is already in the datastore when adding and then readded +with `--no-copy` the block will be added to the filestore but the now +duplicate block will still exists in the normal datastore. +Furthermore, since the block is likely to be pinned it will not be +removed when `repo gc` in run. This is nonoptimal and will eventually +be fixed. For now, you can remove duplicate blocks by running +`filestore rm-dups`.

Instead of using a multi-datastore, mount each datastore under a different mount point and use a multi-blockstore to check each mount point for the block. The first mount checked of the multi-blockstore is considered the "cache", all others are considered read-only. This implies that the garbage collector only removes block from the first mount. This change also factors out the pinlock from the blockstore into its own structure. Only the multi-datastore now implements the GCBlockstore interface. In the future this could be separated out from the blockstore completely. For now caching is only done on the first mount, in the future this could be reworked. The bloom filter is the most problematic as the read-only mounts are not necessary immutable and can be changed by methods outside of the blockstore.

This method will use the (also new) LinkService if it is available to retrieving just the links for a MerkleDAG without necessary having to retrieve the underlying block. For now the main benefit is that the pinner will not break when a block becomes invalid due to a change in the backing file. This is possible because the metadata for a block (that includes the Links) is stored separately and thus always available even if the backing file changes.

Maintenance commands are run on a snapshot of the database that is guaranteed to be in a consistent state. Basically a snapshot is taken before a file is added. To avoid a race condition when deleting a block that has since become valid, the value of the snapshot is compared with the current value in the database and if they don't match then the block is not deleted.

Fix that bug by using Iterators instead when that field is required. Iterators are more efficient than channels anyway.

The orignal "clean" command worked by doing up to three separate passes and removing problem blocks after each pass. The three-pass approach depended on the blocks being deleted from the previous pass. The change introduced in "Filestore: Fix maintenance commands so they are safe to run Online" broke this by using a single snapshot for all passes. This commit reworks the "verify" command so that the three-pass approach is no longer required. Blocks are now normally only reported "incomplete" when one the child nodes is missing, if a child node is just unreadable the status is now reported as "problem". The flag "incomplete-when" can change this behavior. This change eliminates the need for the second (incomplete) pass. To eliminate the need for the thired (orphan) pass in clean, a new "verify-post-orphan" command is created. This command works like "verify" but in addition checks for orphans that would be created if "incomplete" blocks are removed. Also add more comprehensives tests of the "clean" command to the sharness tests to make sure the "clean" does not break again. Other various changes to the "verify" command including adding of a "--no-obj-info" flag that only reports the status and hash. Also fix special "append" status so that it is reported correctly.
