Subject: [PATCH 022/674] test/sharness: fix errors

- core: daemon stdout print to cmd + daemon init checks
- core: fixed bug where the gateway was printed as "API"
- sharness/test-lib: daemon init checks
- sharness/test-lib: portable TCP port check
- sharness/init: fix test bits output
- sharness: use common hashes in one place.
- move t0100-http-gateway -> t0111-gateway-writable
- sharness: test-lib funcs for gateway config
- sharness/t0111-gateway-writable: use sh funcs
- sharness/t0111-gateway-writable: fixes
  - escape all vars (always `cmd "$VAR"` never `cmd $VAR`)
  - use $FILEPATH, not $path
  - last test seems to fail

Subject: [PATCH 023/674] logs: removed all log.Errors unhelpful to users

Let's save log.Error for things the user can take action on.
Moved all our diagnostics to log.Debug. We can ideally reduce them
even further.

Subject: [PATCH 031/674] gateway: dont cache ipns paths

ipns paths are mutable and should not be cached. this error is
a byproduct of the currently messy gateway route. We should split
the /ipfs and /ipns routes up.

Subject: [PATCH 032/674] corehttp: ServeOption supports chaining muxes

Each option now additionally returns the mux to be used by future options. If
every options returns the mux it was passed, the current behavior is unchanged.

However, if the option returns an a new mux, it can mediate requests to handlers
provided by future options:

    return func(n *core.IpfsNode, mux *http.ServeMux) (*http.ServeMux, error) {
      childMux := http.NewServeMux()
      mux.Handle("/", handlerThatDelegatesToChildMux)
      return childMux, nil
    }

Subject: [PATCH 033/674] gateway: attempt to resolve hostname to ipfs path

This allows someone to host a static site by pointing a TXT record at their
content in IPFS, and a CNAME record at an IPFS gateway.

Note that such a setup technically violates RFC1912 (section 2.4; "A CNAME
record is not allowed to coexist with any other data."), but tends to work in
practice.

We may want to consider changing the DNS->IPFS resolution scheme to allow this
scenario to be RFC-compliant (e.g. store the mapping on a well-known subdomain
to allow CNAME records on the domain itself).

Subject: [PATCH 046/674] fix for #1008 and other pinning fixes

This commit adds a new set of sharness tests for pinning, and addresses
bugs that were pointed out by said tests.

test/sharness: added more pinning tests

Pinning is currently broken. See issue #1051. This commit introduces
a few more pinning tests. These are by no means exhaustive, but
definitely surface the present problems going on. I believe these
tests are correct, but not sure. Pushing them as failing so that
pinning is fixed in this PR.

make pinning and merkledag.Get take contexts

improve 'add' commands usage of pinning

FIXUP: fix 'pin lists look good'

ipfs-pin-stat simple script to help check pinning

This is a simple shell script to help check pinning.

We ought to strive towards making adding commands this easy.
The http api is great and powerful, but our setup right now
gets in the way. Perhaps we can clean up that area.

updated t0081-repo-pinning

- fixed a couple bugs with the tests
- made it a bit clearer (still a lot going on)
- the remaining tests are correct and highlight a problem with
  pinning. Namely, that recursive pinning is buggy. At least:
  towards the end of the test, $HASH_DIR4 and $HASH_FILE4 should
  be pinned indirectly, but they're not. And thus get gc-ed out.
  There may be other problems too.

cc @whyrusleeping

fix grep params for context deadline check

fix bugs in pin and pin tests

check for block local before checking recursive pin

Subject: [PATCH 047/674] corehttp: log when server takes a long time to shut
 down

The server may stay alive for quite a while due to waiting on
open connections to close before shutting down. We should
find ways to terminate these connections in a more controlled
manner, but in the meantime it's helpful to be able to see
why a shutdown of the ipfs daemon is taking so long.

Subject: [PATCH 048/674] corehttp: ensure node closing/teardown waits for
 server termination

When closing a node, the node itself only takes care of tearing down
its own children. As corehttp sets up a server based on a node, it
needs to also ensure that the server is accounted for when determining
if the node has been fully closed.

Subject: [PATCH 049/674] corehttp: disable HTTP keep-alive when shutting down
 server

Once the server is asked to shut down, we stop accepting new
connections, but the 'manners' graceful shutdown will wait for
all existing connections closed to close before finishing.

For keep-alive connections this will never happen unless the
client detects that the server is shutting down through the
ipfs API itself, and closes the connection in response.

This is a problem e.g. with the webui's connections visualization,
which polls the swarm/peers endpoint once a second, and never
detects that the API server was shut down.

We can mitigate this by telling the server to disable keep-alive,
which will add a 'Connection: close' header to the next HTTP
response on the connection. A well behaving client should then
treat that correspondingly by closing the connection.

Unfortunately this doesn't happen immediately in all cases,
presumably depending on the keep-alive timeout of the browser
that set up the connection, but it's at least a step in the
right direction.

Subject: [PATCH 061/674] namesys: Add recursive resolution

This allows direct access to the earlier protocol-specific Resolve
implementations.  The guts of each protocol-specific resolver are in
the internal resolveOnce method, and we've added a new:

  ResolveN(ctx, name, depth)

method to the public interface.  There's also:

  Resolve(ctx, name)

which wraps ResolveN using DefaultDepthLimit.  The extra API endpoint
is intended to reduce the likelyhood of clients accidentally calling
the more dangerous ResolveN with a nonsensically high or infinite
depth.  On IRC on 2015-05-17, Juan said:

15:34 <jbenet> If 90% of uses is the reduced API with no chance to
  screw it up, that's a huge win.
15:34 <wking> Why would those 90% not just set depth=0 or depth=1,
  depending on which they need?
15:34 <jbenet> Because people will start writing `r.Resolve(ctx, name,
  d)` where d is a variable.
15:35 <wking> And then accidentally set that variable to some huge
  number?
15:35 <jbenet> Grom experience, i've seen this happen _dozens_ of
  times. people screw trivial things up.
15:35 <wking> Why won't those same people be using ResolveN?
15:36 <jbenet> Because almost every example they see will tell them to
  use Resolve(), and they will mostly stay away from ResolveN.

The per-prodocol versions also resolve recursively within their
protocol.  For example:

  DNSResolver.Resolve(ctx, "ipfs.io", 0)

will recursively resolve DNS links until the referenced value is no
longer a DNS link.

I also renamed the multi-protocol ipfs NameSystem (defined in
namesys/namesys.go) to 'mpns' (for Multi-Protocol Name System),
because I wasn't clear on whether IPNS applied to the whole system or
just to to the DHT-based system.  The new name is unambiguously
multi-protocol, which is good.  It would be nice to have a distinct
name for the DHT-based link system.

Now that resolver output is always prefixed with a namespace and
unprefixed mpns resolver input is interpreted as /ipfs/,
core/corehttp/ipns_hostname.go can dispense with it's old manual
/ipfs/ injection.

Now that the Resolver interface handles recursion, we don't need the
resolveRecurse helper in core/pathresolver.go.  The pathresolver
cleanup also called for an adjustment to FromSegments to more easily
get slash-prefixed paths.

Now that recursive resolution with the namesys/namesys.go composite
resolver always gets you to an /ipfs/... path, there's no need for the
/ipns/ special case in fuse/ipns/ipns_unix.go.

Now that DNS links can be things other than /ipfs/ or DHT-link
references (e.g. they could be /ipns/<domain-name> references) I've
also loosened the ParsePath logic to only attempt multihash validation
on IPFS paths.  It checks to ensure that other paths have a
known-protocol prefix, but otherwise leaves them alone.

I also changed some key-stringification from .Pretty() to .String()
following the potential deprecation mentioned in util/key.go.

Subject: [PATCH 074/674] http/gateway:

- First tab at integrating @krl's new index page

File icons are embedded in side icons.css (QmXB7PLRWH6bCiwrGh2MrBBjNkLv3mY3JdYXCikYZSwLED contains both the icons and bootstrap)

- Fix back links (..)  (fixes #1365)

Thanks @JasonWoof for the insight.  The back links now stop a t the root hash and work for links that do and dont end with a slash.

this commit adds the ability to specify arbitrary HTTP headers
for either the Gateway or the API. simply set the desired headers
on the config:

    ipfs config --json API.HTTPHeaders.X-MyHdr '["meow :)"]'
    ipfs config --json Gateway.HTTPHeaders.X-MyHdr '["meow :)"]'

Subject: [PATCH 079/674] fix API handler to respect referer + exit on CORS

this commit makes the API handler short circuit the request if the
CORS headers say its not allowed. (the CORS handler only sets the
headers, but does not short-circuit)

It also makes the handler respect the referer again. See security
discussion at https://github.com/ipfs/go-ipfs/issues/1532

Subject: [PATCH 081/674] fix cors: defaults should take the port of the
 listener

need to do it this way to avoid VERY confusing situations where
the user would change the API port (to another port, or maybe even
to :0). this way things dont break on the user, and by default,
users only need to change the API address and things should still
"just work"

Subject: [PATCH 085/674] gateway: make IPNSHostname complete

IPNSHostnameOption() touches the URL path only on the way in,
but not on the way out. This commit makes it complete by
touching the following URLs in responses:

- Heading, file links, back links in directory listings
- Redirecting /foo to /foo/ if there's an index.html link
- Omit Suborigin header

Subject: [PATCH 086/674] Localize the scope of context.WithCancel for every
 DAG.Get

Instead put it inside of DAG.Get.
The fix is applied only in the case when the context.WithCancel
before a DAG.Get is also used later on in the scope.

Subject: [PATCH 117/674] Gateway: add support for HTTP OPTIONS request type

OPTIONS is a noop request that is used by the browsers
to check if server will accept cross-site XMLHttpRequest
(indicated by the presence of CORS headers)

Before this fix user could enable CORS headers in the Gateway config,
but XHR failed due to the lack of support for OPTIONS request type
(as described in https://git.io/vzgGe)

Subject: [PATCH 132/674] gateway: enforce allowlist for path prefixes

The gateway accepts an X-Ipfs-Path-Prefix header,
and assumes that it is mounted in a reverse proxy
like nginx, at this path. Links in directory listings,
as well as trailing-slash redirects need to be rewritten
with that prefix in mind.

We don't want a potential attacker to be able to
pass in arbitrary path prefixes, which would end up
in redirects and directory listings, which is why
every prefix has to be explicitly allowed in the config.

Previously, we'd accept *any* X-Ipfs-Path-Prefix header.

Example:

We mount blog.ipfs.io (a dnslink page) at ipfs.io/blog.

nginx_ipfs.conf:

    location /blog/ {
        rewrite "^/blog(/.*)$" $1 break;
        proxy_set_header Host blog.ipfs.io;
        proxy_set_header X-Ipfs-Gateway-Prefix /blog;
        proxy_pass http://127.0.0.1:8080;
    }

.ipfs/config:

    "Gateway": {
        "PathPrefixes": ["/blog"],
        // ...
    },

dnslink:

    > dig TXT _dnslink.blog.ipfs.io
    dnslink=/ipfs/QmWcBjXPAEdhXDATV4ghUpkAonNBbiyFx1VmmHcQe9HEGd

Subject: [PATCH 141/674] Set Cache-Control immutable

Given that /ipfs/ resources never change, we can easily benefit from this
new cache control extension.

Support for this is about to land in Firefox 49:

https://bugzilla.mozilla.org/show_bug.cgi?id=1267474

For more details, there is a good blogpost about this here:

Subject: [PATCH 145/674] metrics: add transport label to p2p_peers_total

Gives us per-transport peers counts:

	ipfs_p2p_peers_total{transport="/ip4/tcp"} 25
	ipfs_p2p_peers_total{transport="/ip6/tcp"} 13
	ipfs_p2p_peers_total{transport="/ip6/udp/utp"} 17

Subject: [PATCH 155/674] gateway: clean up its surface, and remove BlockList

This patch is in preparation for the gateway's extraction.

It's interesting to trace technical debt back to its
origin, understanding the circumstances in which it
was introduced and built up, and then cutting it back
at exactly the right places.

- Clean up the gateway's surface
  The option builder GatewayOption() now takes only
  arguments which are relevant for HTTP handler muxing,
  i.e. the paths where the gateway should be mounted.
  All other configuration happens through the
  GatewayConfig object.

- Remove BlockList
  I know why this was introduced in the first place,
  but it never ended up fulfilling that purpose.
  Somehow it was only ever used by the API server,
  not the gateway, which really doesn't make sense.
  It was also never wired up with CLI nor fs-repo.
  Eventually @krl started punching holes into it
  to make the Web UI accessible.

- Remove --unrestricted-api
  This was holes being punched into BlockList too,
  for accessing /ipfs and /ipn on the API server.
  With BlockList removed and /ipfs and /ipns freely
  accessible, putting this option out of action
  is safe. With the next major release,
  the option can be removed for good.

Subject: [PATCH 173/674] bitswap: protocol extension to handle cids

This change adds the /ipfs/bitswap/1.1.0 protocol. The new protocol
adds a 'payload' field to the protobuf message and deprecates the
existing 'blocks' field. The 'payload' field is an array of pairs of cid
prefixes and block data. The cid prefixes are used to ensure the correct
codecs and hash functions are used to handle the block on the receiving
end.

Subject: [PATCH 174/674] merkledag: change 'Node' to be an interface

Also change existing 'Node' type to 'ProtoNode' and use that most
everywhere for now. As we move forward with the integration we will try
and use the Node interface in more places that we're currently using
ProtoNode.

Subject: [PATCH 194/674] gateway: remove Suborigins as it conflicts the spec

The Suborigins spec was changed and we have to adjust, the spec is still
unstable and it might change in future. Currently the only browser
supporting it (Chrome) errors out on it as it doesn't confront spec it
uses.

Subject: [PATCH 202/674] coreapi: make the interfaces path centric

The new coreiface.Path maps a path to the cid.Cid
resulting from a full path resolution.

The path is internally represented as a go-ipfs/path.Path,
but that doesn't matter to the outside.

Apart from the path-to-CID mapping, it also aims to hold all
resolved segment CIDs of the path. Right now it only exposes
Root(), and only for flat paths a la /ipfs/Qmfoo. In other cases,
the root is nil.

In the future, resolution will internally use
go-ipfs/path.Resolver.ResolvePathComponents and thus always return
the proper resolved segments, via Root(), or a future Segments() func.

- Add coreiface.Path with Cid() and Root().
- Add CoreAPI.ResolvePath() for getting a coreiface.Path.
- All functions now expect and return coreiface.Path.
- Add ParsePath() and ParseCid() for constructing a coreiface.Path.
- Add coreiface.Node and Link which are simply go-ipld-node.Node and Link.
- Add CoreAPI.ResolveNode() for getting a Node from a Path.

* Always use the fully resolved CID from api.ResolveNode
  as the ETag (also for IPNS).

* Format the result as a valid "Strong Validator"
  (double quotes around the encoded CID).

Fixes #3868

Subject: [PATCH 206/674] gateway: re-use resolved path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of resolving a node, we resolve a path. This resolved path
is then re-used for Cat and Ls. This way, a resolve operation is
only done once.

The error messages for a failed resolve is changed from `ipfs cat …`
to `ipfs resolve …` to better reflect the API calls. The test is
updated accordingly.

Subject: [PATCH 211/674] Add Suborigin header to gateway responses (#3209)

This existed before but was disabled in 630596a because the Suborigin spec
changed and it became incompatible.

This commit updates the generated Suborigin header to be conformant with the
latest spec.

Subject: [PATCH 216/674] gateway: don't redirect to trailing slash if it's go
 get

This enables `go get` to parse go-import meta tags from index.html
files stored in IPFS. One tiny step toward whyrusleeping/gx-go#2.

For an import like `ipfs.io/ipfs/QmFoo/mypkg`, the gateway would
previously redirect to `/ipfs/QmFoo/mypkg/` (note the trailing slash),
which the `go get` tool can't deal with.

Thankfully, `go get` sets a URL query parameter (`?go-get=1`) which
we can use to switch off the redirect in this case.

Subject: [PATCH 231/674] gx: update go-stream-muxer

Introduces a new Reset method on streams that kills both sides of the
connection. Close now officially just closes the write side (what it did all
along...)

* Also pull through shiny new go-multiplexer fixes.
* Also pull in go-reuseport update.

namesys/pubsub: integrate namesys pubsub

namesys: integrate pubsub resolvers
namesys/pubsub_test: tweak delays
- trying to make travis happy.
namesys/pubsub: fix duplicate bootstraps
- subscription key is topic, not ipnskey.
namesys/pubsub: no warning needed on cancellation
namesys/pubsub: warning for receive errors
- and more informative error messages at that.
namesys/pubsub_test: smaller test
- make it work with seemingly low fdlimits in travis/macosx.
  also, more informative test failures.
namesys/pubsub: add delay to let pubsub perform handshake
namesys/pubsub: update gx imports
namesys/pubsub_test: preconnect publisher, reduce delays
- preconnects the publisher to the receivers in order to avoid bootstrap
  flakiness with connectivity problems in travis.
  reduces sleeps to 1s for flood propagation (3s seems excessive with 5 hosts).
namesys/pubsub: drop named return values in resolveOnce
- per review comment.
namesys/pubsub: check errors
namesys/pubsub: store bytes in resolver datastore
namesys/pubsub: resolver Cancel
- for canceling subscriptions, pre whyrusleeping's request.
namesys/pubsub: fix resolution without /ipns prefix
- also improve the logging a bit.
namesys/pubsub: don't resolve own keys through pubsub
namesys/pubsub: signal ErrResolveFailed on resolution failure
namesys/pubsub: use sync datastore, resolver lock only for subs
namesys/pubsub_test: coverage for Cancel

Subject: [PATCH 285/674] Feat: Separate "path" from "path/resolver"

Currently the "path" module does two very different things:

* Defines how ipfs paths look like and provides tools to parse/split etc.
* Provides a resolver to resolve paths.

This moves the resolver stuff to `path/resolver` and leaves the
path utilities in `path`.

The result is that now the IPFS `path` package just defines what a path
looks like and becomes a module that can be exported/re-used without problems.
Currently there are circular dependency cycles (resolve_test -> merkledag/utils,
merkledag->path), which the prevent the export of merkledag itself.

Subject: [PATCH 291/674] pre-populate required arguments from request body

This way, we can always assume that indexing a required argument works.

Also:

* test that the command tree doesn't have any obvious bugs (duplicate options,
  arguments in the wrong order, etc).
* simplify the usage ParseBodyArgs.
* remove unnecessary check in the get command.

fixes #4823

Subject: [PATCH 296/674] only resolve dnslinks once in the gateway

IPNS address that doesn't resolve.

fixes #4973

Subject: [PATCH 304/674] correctly handle multi-hop dnslink resolution

Namesys returns `ErrResolveRecursion` when it stops recursing due to a depth

Subject: [PATCH 315/674] wait for all connections to close before exiting on
 shutdown.

Using httpServer.Shutdown will:

1. Close the listener (preventing new connections).
2. Close each connection as outstanding requests finish.

This prevent us from shutting down before outstanding requests get a chance to
respond.

fixes #4055

Subject: [PATCH 326/674] update go-datastore to use []byte values instead of
 {}interface values

* Most of our datastores barf on non []byte values.
* We have to have a bunch of "is this a []byte" checks.
* Saves some allocations.

Subject: [PATCH 343/674] pprof: create HTTP endpoint for setting
 MutexProfileFraction

Allows to dynamically change the MutexProfileFraction to enable and
disable mutex profiling. It should be very useful for detecting
deadlocks, lock contention and general concurrency problems.

How to use:
To enable run: curl -X POST -v 'localhost:5001/debug/pprof-mutex/?fraction=10
To disable: curl -X POST -v 'localhost:5001/debug/pprof-mutex/?fraction=0'

Fraction defines which fraction of events will be profiled. Higher it is
the lower performance impact but less reliable the result.

To fetch the result use:
go tool pprof $PATH_TO_IPFS_BIN http://localhost:5001/debug/pprof/mutex

Subject: [PATCH 353/674] gx: update stuff

* go-datastore and friends: GetSize
* badger: new release, fewer allocations
* go-mplex: send fewer packets
* go-bitswap: pack multiple blocks in a single message, fewer allocations
* go-buffer-pool: replace the buffer pool from go-msgio
* yamux: fixed data race and uses go-buffer-pool for stream read-buffers to
  reduce memory and allocations.
* go-libp2p-secio: get rid of a hot-spot allocation
* go-libp2p-peerstore: reduced allocations (at the cost of some memory)

Subject: [PATCH 354/674] gx: update go-buffer-pool

Turns out that `pool.Put(buf)` had to *allocate* because we needed to turn
`[]byte` into `interface{}`. Apparently, we've never done this correctly we just
never noticed because we never really used buffer pools extensively.

However, since migrating yamux to a buffer-pool backed buffer, this started
showing up in allocation profiles.

Subject: [PATCH 386/674] [http_proxy_over_p2p] httputil.ReverseProxy

Reimplement http-request proxying ala httputil.ReverseProxy.

NB: this is proxies the request synchronously (sends all request-body
before reading any response).

fixes #5138 -- always add user-agent to access-control-allow-headers.
fixes #5888 -- same with content-type.
fixes #5892 -- extend user-provided headers instead of overriding them.

Subject: [PATCH 421/674] show hash if not in original url

Change the template handler to pass the hash to the directory listing template if the original url doesn't contain the hash. The directory listing template will display the hash in grey under the original url if the hash is passed to it.

Subject: [PATCH 473/674] fix and improve the writable gateway

1. Fix handling of PUT. The simple implementation was the correct
   implementation, I have no idea what was going on here.
2. Use MFS everywhere to reduce code duplication and add support for sharded
   directories.
3. _Correctly_ block IPNS.
4. Remove the dependency on `core.IpfsNode`.
5. Remove support for putting empty directories with a well-known CID. It was
   useless as directories are automatically created.

Subject: [PATCH 497/674] fix(gateway): better seeking/sized

1. Require files to have known sizes. We can add support for unknown sizes
_later_ but we can't use ServeContent for those files.
2. Replace the `sizeReadSeeker` with a `lazySeeker`. This one makes no
assumptions about how it's used so we're less likely to run into weird bugs.

We've deprecated this system and have yet to move to a new system. We might as
well remove everything, switch to a new system, then deliberately trace the
entire system.

Subject: [PATCH 509/674] gateway: simplify/improve dnslink rewrite handling

Instead of adding a new fake header (that could be spoofed by the client...),
just read the original request URI from the request object.

This also removes support for suborigins. They have never been implemented in
browsers and it looks like efforts have stalled. We can add support back if we
need it but, well, maintaining support was going to be more trouble than it was
worth.

Subject: [PATCH 511/674] fix(gateway): curl without redirect on localhost

When request is sent to http://localhost:8080/ipfs/$cid response has
HTTP 301 status code and "Location" header with redirect destination at
$cid.ipfs.localhost:8080

Redirect is followed by browsersi, but not by commandline tools.
Status 301 is ignored by curl in default mode: it will print response
and won't follow redirect, user needs to add -L for that.

To fix curl, we return correct payload in body of HTTP 301 response,
but set Clear-Site-Data header to ensure Origin sandbox can't be abused.

This requires a surgical workaround:
If Location header is present in ResponseWriter's Header map,
we ensure http.ServeContent() returns HTTP 301

Subject: [PATCH 512/674] HTTP API: Disallow GET requests on API

This commit upgrades go-ipfs-cmds and configures the commands HTTP API Handler
to only allow POST/OPTIONS, disallowing GET and others in the handling of
command requests in the IPFS HTTP API (where before every type of request
method was handled, with GET/POST/PUT/PATCH being equivalent).

The Read-Only commands that the HTTP API attaches to the gateway endpoint will
additional handled GET as they did before (but stop handling PUT,DELETEs).

By limiting the request types we address the possibility that a website
accessed by a browser abuses the IPFS API by issuing GET requests to it which
have no Origin or Referrer set, and are thus bypass CORS and CSRF protections.

This is a breaking change for clients that relay on GET requests against the
HTTP endpoint (usually :5001). Applications integrating on top of the
gateway-read-only API should still work (including cross-domain access).

Subject: [PATCH 524/674] Gateway renders pretty 404 pages if available

In the same way that an `index.html` file is rendered, if one is present, when the
requested path is a directory, now an `ipfs-404.html` file is rendered if
the requested file is not present within the specified IPFS object.

`ipfs-404.html` files are looked for in the directory of the requested path and each
parent until one is found, falling back on the well-known 404 error message.

Subject: [PATCH 526/674] fix(gateway): ensure directory listings have
 Content-Type text/html

Files already have an explicit Content-Type set. Be sure to do this for
directory listings as well to avoid a fallback to autodetection in
net/http. That fallback fails when a ResponseWriter is installed that
performs compression.

Subject: [PATCH 527/674] fix: support directory listings even if a 404 page is
 present

fixes https://github.com/ipfs/go-ipfs/pull/4233#issuecomment-631454543

Basically, there's a trade-off here:

1. We can support directory listings while supporting 404 pages (this PR).
2. If a 404 page is present, directory listings don't work.

Given that option 1 is more flexible and users shouldn't be _too_ confused if
they land on a directory with no index.html page, I've gone with that option.

Subject: [PATCH 528/674] Include the git blob id of the dir-index bundle in
 the ETag

While the content of raw files retrieved via the gateway should never
change, the look and feel of the directory index can and will change
between versions of go-ipfs.

Incorporate the hash of assets/bindata.go into the ETag when appropriate

Subject: [PATCH 537/674] feat: support ED25519 libp2p-key in subdomains

This:

- adds subdomain gateway support for ED25519 CIDs in a way that fits in
  a single DNS label to enable TLS for every IPNS website.

- cleans up subdomain redirect logic and adds more explicit error
  handling.

TL;DR on router logic:

When CID is longer than 63 characters, router at /ipfs/* and /ipns/*
converts to Base36, and if that does not help, returns a human readable
400 Bad Request error.

Addressing code review:
https://github.com/ipfs/go-ipfs/pull/7441#pullrequestreview-440043209

refactor: use b36 for all libp2p-keys in subdomains

Subject: [PATCH 540/674] feat: wildcard support for public gateways

Add support for one or more wildcards in the hostname definition
of a public gateway. This is useful for example to support easily
multiples environment.

Wildcarded hostname are set in the config as for example "*.domain.tld".

Subject: [PATCH 541/674] test(gateway): IPNS cleanup and implicit defaults fix

This ensures implicit defaults are always present, even when
Gateway.PublicGateways is defined in the config.

User still can disable them, but needs to do it per hostname.

Subject: [PATCH 546/674] feat(gateway): ?filename with download=true

This implements 'attachment' mode triggered then
?filename parameter is accompanied with &download=true

When Content-Disposition: attachment is detected by a modern browser
it will skip rendering and immediately open the "save as" dialog,
making this useful feature for using IPFS gateway as target of
"Download" links on various websites.

Parameter name was suggested in:
https://github.com/ipfs/go-ipfs/pull/4177#issuecomment-414870327

Subject: [PATCH 553/674] test(gw): add t0115-gateway-dir-listing.sh to
 sharness

This adds proper end-to-end tests for directory listing on Gateway port
that protects us against regressions oni each gw type:
- path gateway
- subdomain gateway
- dnslink website gateway

Tests cover:
- etag/unicode support
- breadcrumbs
- file name column
- hash column

This adds localhost ipv6 addresses to the allowlist for use in browser
context and fixes WebUI on ipv6-only deployments: http://[::1]:5001/webui

We were missing CORS/Origin tests for API port so I've added basic ones
and included localhost/127.0.0.1/::1 variants.

Subject: [PATCH 563/674] feat(gw): support inlined DNSLink names with TLS

Problem statement and rationale for doing this can be found under
"Option C" at: https://github.com/ipfs/in-web-browsers/issues/169

TLDR is:

`https://dweb.link/ipns/my.v-long.example.com` can be loaded from a
subdomain gateway with a wildcard TLS cert if represented as a single
DNS label: `https://my-v--long-example-com.ipns.dweb.link`

This kinda enables to run their custom DNS resolver with custom
tlds/names that are independent from the public DNS network.

Subject: [PATCH 566/674] feat: support requests from registerProtocolHandler

This commit adds support for requests produced by navigator.registerProtocolHandler on gateways. Now one can register `dweb.link` as an URI handler for `ipfs://`:

```
navigator.registerProtocolHandler('ipfs', 'https://dweb.link/ipfs/?uri=%s', 'ipfs resolver')
```

Then opening `ipfs://QmbWqxBEKC3P8tqsKc98xmWNzrzDtRLMiMPL8wBuTGsMnR` will produce an HTTP GET call to:

```
https://dweb.link/ipfs?uri=ipfs%3A%2F%2FQmbWqxBEKC3P8tqsKc98xmWNzrzDtRLMiMPL8wBuTGsMnR
```

The query parameter `uri` will now be parsed and the given content identifier resolved via:

`https://dweb.link/ipfs/QmbWqxBEKC3P8tqsKc98xmWNzrzDtRLMiMPL8wBuTGsMnR`

Subject: [PATCH 570/674] fix: remove use of Clear-Site-Data

We used Clear-Site-Data to cushion transition period for local gateway
exposed at http://localhost while we were still figuring out
security-related details.

In the final implementation subdomain gateways are not tied to a
hostname explicitly, which removes the risk of cookies leaking,
removing the need for the header.

Turns out it causes issues for Firefox users, so let's just remove it.

Closes https://github.com/ipfs-shipyard/ipfs-companion/issues/977

Subject: [PATCH 573/674] Extract the namesys and the keystore submodules

Namesys is a very useful submodule. Given a ValueStore and a Datastore it can
resolve and publish /ipns/ paths.

This functionality does not need to be sequestered inside go-ipfs as it can
and should be used without IPFS, for example, for implementing lightweight
IPNS publishing services or for resolving /ipns/ paths.

"keystore" extraction was necessary, as there is a dependency to it in
namesys. Keystore is also a useful module by itself within the stack.

Fixes #6537

Subject: [PATCH 591/674] fix: abort when we fail to resolve CIDs

can't, there's probably something wrong with the directory.

Subject: [PATCH 598/674] add more logging to flaky TestPeersTotal

Cannot reproduce the flakiness at the moment. The report suggests that connections are established on different transports. Adding logging to show what these transports are.

Subject: [PATCH 602/674] feat: go-libp2p 0.16, UnixFS autosharding and
 go-datastore with contexts (#8563)

* plumb through go-datastore context changes

* update go-libp2p to v0.16.0
* use LIBP2P_TCP_REUSEPORT instead of IPFS_REUSEPORT
* use relay config
* making deprecation notice match the go-ipfs-config key
* docs(config): circuit relay v2
* docs(config): fix links and headers
* feat(config): Internal.Libp2pForceReachability

This switches to config that supports setting and reading
Internal.Libp2pForceReachability OptionalString flag

* use configuration option for static relays

* chore: go-ipfs-config v0.18.0

https://github.com/ipfs/go-ipfs-config/releases/tag/v0.18.0

* feat: circuit v1 migration prompt when Swarm.EnableRelayHop is set (#8559)
* exit when Swarm.EnableRelayHop is set
* docs: Experimental.ShardingEnabled migration

This ensures existing users of global sharding experiment get notified
that the flag no longer works + that autosharding happens automatically.

For people who NEED to keep the old behavior (eg. have no time to
migrate today) there is a note about restoring it with
`UnixFSShardingSizeThreshold`.

* chore: add dag-jose code to the cid command output

* add support for setting automatic unixfs sharding threshold from the config
* test: have tests use low cutoff for sharding to mimic old behavior
* test: change error message to match the current error
* test: Add automatic sharding/unsharding tests (#8547)
* test: refactored naming in the sharding sharness tests to make more sense

* ci: set interop test executor to convenience image for Go1.16 + Node
* ci: use interop master

Subject: [PATCH 610/674] fix: allow ipfs-companion browser extension to access
 RPC API (#8690)

* fix: add companion ids to allow origins

- fixes #8689
- Adds the chrome-extension ids for ipfs-companion and
ipfs-companion-beta to the allowed origins list, this
allows us to accesss ipfs api from a manifest v3 extension.
- added tests in t0401-api-browser-security.sh

* fix: companion when custom CORS *-Origin is set

Companion extension should be able to access RPC API even when custom
Access-Control-Allow-Origin is set

Subject: [PATCH 611/674] feat(gateway): Block and CAR response formats (#8758)

* feat: serveRawBlock implements ?format=block
* feat: serveCar implements ?format=car
* feat(gw): ?format= or Accept HTTP header

- extracted file-like content type responses to separate .go files
- Accept HTTP header with support for application/vnd.ipld.* types

* fix: use .bin for raw block content-disposition

.raw may be handled by something, depending on OS, and .bin
seems to be universally "binary file" across all systems:
https://en.wikipedia.org/wiki/List_of_filename_extensions_(A%E2%80%93E)

* refactor: gateway_handler_unixfs.go

- Moved UnixFS response handling to gateway_handler_unixfs*.go files.
- Removed support for X-Ipfs-Gateway-Prefix (Closes #7702)

* refactor: prefix cleanup and readable paths

- removed dead code after X-Ipfs-Gateway-Prefix is gone
  (https://github.com/ipfs/go-ipfs/issues/7702)
- escaped special characters in content paths returned with http.Error
  making them both safer and easier to reason about (e.g. when invisible
  whitespace Unicode is used)

Subject: [PATCH 612/674] feat: add gateway histogram metrics (#8443)

* feat(gw): response type histogram metrics

- response-type agnostic firstContentBlockGetMetric which counts the
  latency til the first content block.

- car/block/file/gen-dir-index duration histogram metrics that show how
  long each response type takes

* docs: improve metrics descriptions
* feat: more gw histogram buckets

0.05, 0.1, 0.25, 0.5, 1, 2, 5, 10, 30, 60 secs
as suggested in reviews at https://github.com/ipfs/go-ipfs/pull/8443

Subject: [PATCH 613/674] fix(gw): validate requested CAR version (#8835)

* fix(gw): validate requested CAR version

This adds validation of 'application/vnd.ipld.car;version=n' passed
in the Accept header by HTTP clients to align Gateway behavior with
the spec submitted to IANA.

* test: fix comment in test/sharness/t0118-gateway-car.sh

Subject: [PATCH 614/674] feat: add basic gateway tracing (#8595)

* add deprecation warning when tracer plugins are loaded
* add response format attribute to span in gateway handler
* add note about tracing's experimental status in godoc
* add nil check for TTL when adding name span attrs
* add basic sharness test for integration with otel collector
* add nil check in UnixFSAPI.processLink
* test: sharness check all json objs for swarm span
* add env var docs to docs/environment-variables.md
* chore: pin the otel collector version
* add tracing spans per response type (#8841)
* docs: tracing with jaeger-ui

Subject: [PATCH 615/674] fix(gw): update metrics only when payload data sent
 (#8827)

* fix: report gateway http metrics only when response is successful
* fix(gw): 304 Not Modified as no-op

This fix ensures we don't do any additional work when Etag match
what user already has in their own cache.

This ensures that child contexts are passed around between
the handlers so that traces show the call hierarchy correctly.

Subject: [PATCH 618/674] Remove gobindata

Since go1.16, there are built in tools that allow for embeding
filesystem inside the binary. We now make use of the `embed` package to
have all files put into the binary, removing the need to generate the
files and removes dependencies

Subject: [PATCH 621/674] feat(gw): improved If-None-Match support (#8891)

Improves the way we handle If-None-Match header:
- Support for more than one Etag passed in If-None-Match
- Match both strong and weak Etags to maximize caching across
  various HTTP clients and libraries (some send weak Etags by default)
- Support for wildcard '*'
- Tests for If-None-Match behavior

Subject: [PATCH 622/674] feat(gateway): Gateway.FastDirIndexThreshold (#8853)

* fix(core/gateway): option to limit directory size listing

* feat(gw): HTMLDirListingLimit

This is alternative take on the way we limit the HTML listing output.
Instead of a hard cut-off, we list up to HTMLDirListingLimit.
When a directory has more items than HTMLDirListingLimit we show
additional header and footer informing user that only $HTMLDirListingLimit
items are listed. This is a better UX.

* fix: 0 disables Gateway.HTMLDirListingLimit

* refactor: Gateway.FastDirIndexThreshold

see explainer in docs/config.md

* refactor: prealoc slices

* docs: Gateway.FastDirIndexThreshold

* refactor: core/corehttp/gateway_handler.go

https://github.com/ipfs/go-ipfs/pull/8853#discussion_r851437088

* docs: apply suggestions from code review

Subject: [PATCH 624/674] fix: JS caching via Access-Control-Expose-Headers
 (#8984)

This fix safelists additional headers allowing JS running on websites to
read them when IPFS resource is downloaded via Fetch API.

These headers provide metadata necessary for making smart caching
decisions when IPFS resources are downloaded via Service Worker or a
similar middleware on the edge.

Subject: [PATCH 642/674] fix(gw): ensure dir URLs have trailing slash

This fixes a regression around directory listing and index.html hosting.
Seems that during one of recent refactors code changed and we no longer
check for trailing slash in HTTP request path, but look at content path
instead.

This cleans this up and also ensures dir behavior is the same for
both index.html hosting and dir-index-html (generated listing).

It also adds more tests so we catch any future regressions.

+// Resolving a UnixFS path involves determining if the provided `path.Path` exists and returning the `path.Resolved`
+// corresponding to that path. For UnixFS, path resolution is more involved.
+//
+// When a path under requested CID does not exist, Gateway will check if a `_redirects` file exists
+// underneath the root CID of the path, and apply rules defined there.
+// See sepcification introduced in: https://github.com/ipfs/specs/pull/290
+//
+// Scenario 1:
+// If a path exists, we always return the `path.Resolved` corresponding to that path, regardless of the existence of a `_redirects` file.
+//
+// Scenario 2:
+// If a path does not exist, usually we should return a `nil` resolution path and an error indicating that the path
+// doesn't exist.  However, a `_redirects` file may exist and contain a redirect rule that redirects that path to a different path.
+// We need to evaluate the rule and perform the redirect if present.
+//
+// Scenario 3:
+// Another possibility is that the path corresponds to a rewrite rule (i.e. a rule with a status of 200).
+// In this case, we don't perform a redirect, but do need to return a `path.Resolved` and `path.Path` corresponding to
+// the rewrite destination path.
+//
+// Note that for security reasons, redirect rules are only processed when the request has origin isolation.

Subject: [PATCH 662/674] fix(gateway): JSON when Accept is a list

Block/CAR responses always had single explicit type, and we did not bother
with implementing/testing lists.

With the introduction of JSON people may start passing a list.
This is the most basic fix which will return on the first matching
type (in order). This does not implements weights (can be added in
future, if needed).

Closes #9520

Subject: [PATCH 664/674] fix(gateway): undesired conversions to dag-json and
 friends (#9566)

* fix(gateway): do not convert unixfs/raw into dag-* unless explicit
* fix(gateway): keep only dag-json|dag-cbor handling
* fix: allow requesting dag-json as application/json
- adds bunch of additional tests including JSON file on UnixFS
- fix: dag-json codec (0x0129) can be returned as plain json
- fix: json codec (0x0200) cna be retrurned as plain json
* fix: using ?format|Accept with CID w/ codec works
* docs(changelog): cbor and json on gateway

Subject: [PATCH 665/674] fix(gateway): JSON when Accept is a list

Block/CAR responses always had single explicit type, and we did not bother
with implementing/testing lists.

With the introduction of JSON people may start passing a list.
This is the most basic fix which will return on the first matching
type (in order). This does not implements weights (can be added in
future, if needed).

Closes #9520

Subject: [PATCH 667/674] fix(gateway): undesired conversions to dag-json and
 friends (#9566)

* fix(gateway): do not convert unixfs/raw into dag-* unless explicit
* fix(gateway): keep only dag-json|dag-cbor handling
* fix: allow requesting dag-json as application/json
- adds bunch of additional tests including JSON file on UnixFS
- fix: dag-json codec (0x0129) can be returned as plain json
- fix: json codec (0x0200) cna be retrurned as plain json
* fix: using ?format|Accept with CID w/ codec works
* docs(changelog): cbor and json on gateway

+# Required Assets for the Gateway
+
+> DAG and Directory HTML for HTTP gateway
+
+## Updating
+
+When making updates to the templates, please note the following:
+
+1. Make your changes to the (human-friendly) source documents in the `src` directory.
+2. Before testing or releasing, go to `assets/` and run `go generate .`.
+
+## Testing
+
+1. Make sure you have [Go](https://golang.org/dl/) installed
+2. Start the test server, which lives in its own directory:
+
+```bash
+> cd test
+> go run .
+```
+
+This will listen on [`localhost:3000`](http://localhost:3000/) and reload the template every time you refresh the page. Here you have two pages:
+
+- [`localhost:3000/dag`](http://localhost:3000/dag) for the DAG template preview; and
+- [`localhost:3000/directory`](http://localhost:3000/directory) for the Directory template preview.
+
+If you get a "no such file or directory" error upon trying `go run .`, make sure you ran `go generate .` to generate the minified artifact that the test is looking for.
