* swarm/api: url scheme bzz-hash to get hashes of swarm content (#15238)
Update URI to support bzz-hash scheme and handle such HTTP requests by
responding with hash of the content as a text/plain response.
* swarm/api: return hash of the content for bzz-hash:// requests
* swarm/api: revert "return hash of the content for bzz-hash:// requests"
Return hashes of the content that would be returned by bzz-raw
request.
* swarm/api/http: handle error in TestBzzGetPath
* swarm/api: remove extra blank line in comment
* swarm/api: url scheme bzz-list for getting list of files from manifest
Replace query parameter list=true for listing all files contained
in a swarm manifest with a new URL scheme bzz-list.
* swarm: replaace bzzr and bzzi schemes with bzz-raw and bzz-immutable
New URI Shemes are added and old ones are deprecated, but not removed.
Old Schemes bzzr and bzzi are functional for backward compatibility.
* swarm/api: completely remove bzzr and bzzi schemes
Remove old schemes in favour of bzz-raw and
bzz-immutable.
* swarm/api: revert "completely remove bzzr and bzzi schemes"
Keep bzzr and bzzi schemes for backward compatibility. At least
until 0.3 swarm release.
This commit adds a TOML configuration option to swarm. It reuses
the TOML configuration structure used in geth with swarm
customized items.
The commit:
* Adds a "dumpconfig" command to the swarm executable which
allows printing the (default) configuration to stdout, which
then can be redirected to a file in order to customize it.
* Adds a "--config <file>" option to the swarm executable which will
allow to load a configuration file in TOML format from the
specified location in order to initialize the Swarm node The
override priorities are like follows: environment variables
override command line arguments override config file override
default config.
If the file already existed, the WriteResponse.Size was being set
as the length of the entire file, not just the amount that was
written to the existing file.
Fixes#15216
bmt is a new package that provides hashers for binary merkle tree hashes on
size-limited chunks. the main motivation is that using BMT hash as the chunk
hash of the swarm hash offers logsize inclusion proofs for arbitrary files on a
32-byte resolution completely viable to use in challenges on the blockchain.
Previously, NewManifest was asynchronous so subsequent code which tried
to use the returned manifest could error as the manifest was not yet
persisted.
The previous attempt to use --ethapi as a fallback if --ens-api is not
set does not work because --ens-api has a default value, and also
setting --ens-api to "" is the suggested way to disable ENS lookups.

The code looked for /usr/bin/diskutil on darwin, but it's actually
located in /usr/sbin. Fix that by not specifying the absolute path.
Also remove weird timeout construction and extra whitespace.
This PR adds a Swarm development environment which can be run in a
Docker container and provides scripts for building binaries and running
Swarm clusters.
Previously, resolve errors were being swallowed and the returned error
was a generic "not a content hash" which isn't helpful.
This updates the Resolve function to fail fast rather than only
returning an error at the end, and also adds test coverage.
- Moved fuse related code in a new package, swarm/fuse
- Added write support
- Create new files
- Delete existing files
- Append to files (with limitations)
- More test coverage
This PR deprecates the file related RPC calls in favour of an improved HTTP API.
The main aim is to expose a simple to use API which can be consumed by thin
clients (e.g. curl and HTML forms) without the need for complex logic (e.g.
manipulating prefix trie manifests).
This adds a swarm ls command which lists files and directories stored in a
manifest. Rather than listing all files, it uses "directory prefixes" in case there are a
lot of files in a manifest but you just want to traverse it.
This also includes some refactoring to the tests and the introduction of a
swarm/api/client package to make things easier to test.
* swarm/api: fix build/tests on unsupported platforms
Skip FUSE tests if FUSE is unavailable and change build constraints so
the 'lesser' platforms aren't mentioned explicitly. The test are
compiled on all platforms to prevent regressions in _fallback.go
Also gofmt -w -s because why not.
* internal/web3ext: fix swarmfs wrappers
Remove inputFormatter specifications so users get an error
when passing the wrong number of arguments.
* swarm/api: improve FUSE-related logging and APIs
The API now returns JSON objects instead of strings.
Log messages for invalid arguments are removed.
There is no need to depend on the old context package now that the
minimum Go version is 1.7. The move to "context" eliminates our weird
vendoring setup. Some vendored code still uses golang.org/x/net/context
and it is now vendored in the normal way.
This change triggered new vet checks around context.WithTimeout which
didn't fire with golang.org/x/net/context.
* common/math: optimize PaddedBigBytes, use it more
name old time/op new time/op delta
PaddedBigBytes-8 71.1ns ± 5% 46.1ns ± 1% -35.15% (p=0.000 n=20+19)
name old alloc/op new alloc/op delta
PaddedBigBytes-8 48.0B ± 0% 32.0B ± 0% -33.33% (p=0.000 n=20+20)
* all: unify big.Int zero checks
Various checks were in use. This commit replaces them all with Int.Sign,
which is cheaper and less code.
eg templates:
func before(x *big.Int) bool { return x.BitLen() == 0 }
func after(x *big.Int) bool { return x.Sign() == 0 }
func before(x *big.Int) bool { return x.BitLen() > 0 }
func after(x *big.Int) bool { return x.Sign() != 0 }
func before(x *big.Int) int { return x.Cmp(common.Big0) }
func after(x *big.Int) int { return x.Sign() }
* common/math, crypto/secp256k1: make ReadBits public in package math
* swarm/network: integrity on incoming known chunks
* swarm/network: fix integrity check for incoming chunks
* swarm/storage: imrpoved integrity checking on chunks
* dbstore panics on corrupt chunk entry an prompts user to run cleandb
* memstore adds logging for garbage collection
* dbstore refactor item delete. correct partial deletes in Get
* cmd/swarm: added cleandb subcommand
