Ignore design docs in shards db in couch scanner

Ignore design docs in shards db in couch scanner

Sometimes eunit tests leave design docs behind and the scanner would crash with
a case clause error. Test cleanup was fixed in another commit, however it's
possible for users to have their own design documents, so we should handle that
case anyway.

Add QuickJS as a Javascript engine option

Author: Nick Vatamaniuc
Author Date: 2022-11-26 05:14:01 UTC

Add QuickJS as a Javascript engine option

https://bellard.org/quickjs

Some benefits over SM:

 * Small. We're using 6 or so C files vs 700+ SM91 C++ files.

 * Built with Apache CouchDB as opposed having to maintain a separate SM
   package, like for RHEL9, for instance, where they dropped support for SM
   already. (see https://github.com/apache/couchdb/issues/4154).

 * Embedding friendly. Designed from ground-up for embedding. SM has been
   updating the C++ API such that we have to keep copy-pasting new versions of
   our C++ code every year or so. (see
   https://github.com/apache/couchdb/pull/4305).

 * Easy to modify to accept Spidermonkey 1.8.5 top level functions for
   map/reduce code so we don't have have to parse the JS, AST transform it, and
   then re-compile it.

 * Configurable runtime feature set - can disable workers, promises and other
   API and features which may not work well in a backend JS environment. Some
   users may want more, some may want to disable even Date(time) features to
   hedge again Spectre-style attacks (spectreattack.com).

 * Allows granular time (reduction) tracking if we wanted to provide a runtime
   allowance for each function.

 * Better sandboxing. Creating a whole JSRuntime takes only 300 microseconds, so
   we can afford to do that on reset. JSRuntimes cannot share JS data or object
   between them.

 * Seems to be faster in preliminary benchmarking with small
   concurrent VDU and view builds:
     https://gist.github.com/nickva/ed239651114794ebb138b1f16c5f6758
   Results seem promising:
     - 4x faster than SM 1.8.5
     - 5x faster than SM 91
     - 6x reduced memory usage per couchjs process (5MB vs 30MB)

 * Allows compiling JS bytecode ahead of time a C array of bytes.

QuickJS can be built alongside Spidermonkey and toggled on/off at runtime:

```
./configure --dev --js-engine=quickjs
```

This makes it the default engine. But Spidermonkey can still be set in the
config option.

```
[couchdb]
js_engine = spidermonkey | quickjs
```

To test individual views, without switching the default use the
`javascript_quickjs` language in the design docs. To keep using Spidermonkey
engine after switching the default, can use `javascript_spidermonkey` language
in design docs. However, language selection will reset the view and the view
will have to be rebuilt.

It's also possible to build without Spidermonkey support completely by using:
```
./configure --disable-spidermonkey
```

mango: fix $beginsWith range

Author: Will Holley
Author Date: 2023-11-02 09:26:11 UTC

mango: fix $beginsWith range

In the intial implementation of $beginsWith, the range calculation
for json indexes mistakenly appends an integer with the size of
8 bits which gets maxed out at FF, rather than building a binary
with an extra 3 bytes at the end.

This commit fixes the `mango_idx_view:range/5` by correctly appending
the `U+FFFF` code point to create a utf-8 encoded binary. Additionally,
the Erlang `utf8` binary type ensures the result
is a valid utf8 string. If `Arg` is not a utf8 binary, this will
throw a badarg error.

We expect `Arg` strings to be a valid utf8 but, to be safe,
`mango_selector:norm_ops/1` is enhanced to verify
that any argument to `$beginsWith` is a utf8 string.

Author: Robert Newson
Author Date: 2023-08-22 12:21:40 UTC

A _find request can run for a very long time (on large databases when the
selector matches no index) and this continues even if the client disconnects.

We want to stop the fabric work when there is no client to receive the
result. fabric_streams already kills the workers if the coordinating process
dies but in this circumstance it does not.

this commit enhances (and renames) the existing cleanup process to be a watchdog. If
enabled, the watchdog needs to be kicked regularly (by whatever activity we
think indicates its worth continuing) or it will terminate the process it is
watching, and kill the worker processes also.

Currently only mango_httpd:handle_find_req enables the watchdog and it only
kicks the watchdog when it enqueues a row to be returned (i.e, only on selector
matches).

support Websocket protocol for continuous response

This isn't full Websocket protocol as mochiweb doesn't have
the plumbing but it's still useful.

The endpoint will not return a pong if the client sends a ping
but if the heartbeat parameter is used the server will send pongs
at that right as a keep-alive.

If the server encounters an error it sends a Close message with
the reason before closing the socket.

docs(mango): match description of `$mod` with reality

The remainder argument for the `$mod` operator can be zero, while
its documentation suggests otherwise. It actually covers a very
realistic use case where divisibility is expressed.

Neither related restrictions could be identified in the sources
[1] nor MongoDB forbids this [2]. Tests also seem to exercise this
specific case [3]. Thanks @iilyak for checking on these.

Maybe return bad_content_type on _session POST

Currently, when POSTing to `/_session` with a Content-Type header
other than either `application/x-www-form-urlencoded` or
`application/json`, the error response can be surprising.

Database Encryption Support

CouchDB can optionally encrypt databases and views.

We use AES in Counter Mode, which ensures we can encrypt and decrypt
any section of the file without padding or alignment. The ciphertext
is the same length as the plaintext. This mode provides
confidentiality but not authentication.

Key management is configurable, a system administrator can write a
module implementing the couch_encryption_manager behaviour with any
implementation.

Integrate raft algorithm (WIP)

Integrate raft algorithm (WIP)

couch_raft.erl is a complete implementation of the raft algorithm but
currently only manages an in-memory state machine and log.

Preliminary work is also here to add a new btree inside the `.couch`
files, which will be the real raft log. The intent is that log entries
can be removed from this log and applied to by_id and by_seq trees
atomically.

raft log is preserved over compaction in the same manner as local
docs, all entries are slurped into memory and written in one
pass. This should be fine as the log should stay short, committed
entries can be promptly removed. It's probably not fine for local
docs, though...

Anyway, it's progress and hopefully we're going somewhere cool.

Autodetect spidermonkey version in ./configure

I have struggled with this point when building
couchDB, because it's written nowhere in the documentation
that you need to configure the version properly.

It seems that other people had the problem as well:
https://couchdb.slack.com/archives/C49LEE7NW/p1632249155263400

The updated configure script automatically finds
out the installed library version. It also introduces
a dependency on `sed`, `ldconfig` and `head`,
and remove the default to version 1.8.5 which is old
and not in most distributions anymore.

The argument was also removed from the CI scripts
because it does not exist anymore.

fix case_clause when HitId and DocId do not match when include_docs=true

Author: Tony Sun
Author Date: 2021-10-21 00:07:06 UTC

fix case_clause when HitId and DocId do not match when include_docs=true

Sometimes, a clouseau index may become out of sync with the db or
become corrupt under certain conditions (heap exhaustion, garbage collection).
This leads to certain HitIds that get returned which may not exist
in the current db. Before this fix, we assume the Hit's Id will
automatically match an Id return from:

fabric:all_docs(DbName, fun callback/2, [], [{keys, DocIds}, {include_docs, true}]).

When the document does not exist, {error, false} is returned for the row.
This fix accounts for this scenario and possible other scenarios
by returning an error to the user and also logging the error when the
Hit Id does not match what is returned from the _all_docs call.

feat(views): cache function compilation. Closes #3517.

Since supporting SpiderMonkey versions > 1.8.5 we compile design
doc functions of the form `function(args) { /* impl */ }` into a
form that is recognise by newer JS engines.

For reduce views, this means a transpilation happens on each
reduce call over the couchjs protocol, which is once for every
level in the b+tree plus one final rereduce across all shards.

down reduce view indexing/querying.

This patch adds caching to the compilation function. This is
implemented by way of producing a SHA-256 hash of all incoming
JS functions and caching them in a global object in the memory
of a `couchjs` process.

The cache is cleared when a `add_fun` message is received, which
happens before new map functions from a new ddoc are loaded into
`couchjs`. This ensures that only functions from a single view &
security context are ever loaded into the cache.

SHA-256 was chosen because it is producing collisions that are
also valid JS functions is unlikley.

This specific SHA-256 implementation was chosen because:
- it is favourably licensed (MIT)
- taken from the Deno (https://deno.land) project, (h/t Martin
  Sonnenholzer for the tip)so we can be reasonably assured this
  has been tested thoroughly.

error.

Require subscribers to wait until indexer finishes

Author: Adam Kocoloski
Author Date: 2021-03-03 03:17:47 UTC

Require subscribers to wait until indexer finishes

This clause allowed a subscriber to start reading a view as soon as the
indexer made it past the sequence of interest. The trouble with that
approach is the resulting view is not directly related to any snapshot
of the underlying DB. Waiting until the indexer finishes allows us to
provide better semantics, where the view observes a consistent snapshot
of the database at some point in time >= the requested sequence.

In order to see this work through the view reader should explicitly set
the read version of FDB to match the commit version introduced by the
indexer, to avoid seeing partial results from a follow-on indexing job.

In this case we should return the field as is without any attempt to
decompress or decode it. This PR brings the approach we use in `chttpd`
into `couch_httpd`.
