v2.5.0 (XXXX-XX-XX)
-------------------
* fixed issue #1226: arangod log issues
* added additional logger if arangod is started in foreground mode on a tty
* added AQL optimizer rule "move-calculations-down"
* use exclusive native SRWLocks on Windows instead of native mutexes
* added AQL functions MD5, SHA1, and RANDOM_TOKEN.
* reduced number of string allocations when parsing certain AQL queries
parsing numbers (integers or doubles) does not require a string allocation
per number anymore
* RequestContext#bodyParam now accepts arbitrary joi schemas and rejects invalid (but well-formed) request bodies.
* enforce that AQL user functions are wrapped inside JavaScript function () declarations
AQL user functions were always expected to be wrapped inside a JavaScript function, but previously
this was not enforced when registering a user function. Enforcing the AQL user functions to be contained
inside functions prevents functions from doing some unexpected things that may have led to undefined
behavior.
v2.4.2 (2015-XX-XX)
-------------------
* improved number of results estimated for nodes of type EnumerateListNode and SubqueryNode
in AQL explain output
* added AQL explain helper:
require("org/arangodb/aql/explainer").explain(query);
* enable use of indexes for certain AQL conditions with non-equality predicates, in
case the condition(s) also refer to indexed attributes
The following queries will now be able to use indexes:
FILTER a.indexed == ... && a.indexed != ...
FILTER a.indexed == ... && a.nonIndexed != ...
FILTER a.indexed == ... && ! (a.indexed == ...)
FILTER a.indexed == ... && ! (a.nonIndexed == ...)
FILTER a.indexed == ... && ! (a.indexed != ...)
FILTER a.indexed == ... && ! (a.nonIndexed != ...)
FILTER (a.indexed == ... && a.nonIndexed == ...) || (a.indexed == ... && a.nonIndexed == ...)
FILTER (a.indexed == ... && a.nonIndexed != ...) || (a.indexed == ... && a.nonIndexed != ...)
* Fixed spuriously occurring "collection not found" errors when running queries on local
collections on a cluster DB server
* Fixed upload of Foxx applications to the server for apps exceeding approx. 1 MB zipped.
* Malformed Foxx applications will now return a more useful error when any route is requested.
In Production a Foxx app mounted on /app will display an html page on /app/* stating a 503 Service temporarily not available.
It will not state any information about your Application.
Before it was a 404 Not Found without any information and not distinguishable from a correct not found on your route.
In Development Mode the html page also contains information about the error occured.
* Unhandled errors thrown in Foxx routes are now handled by the Foxx framework itself.
In Production the route will return a status 500 with a body {error: "Error statement"}.
In Development the route will return a status 500 with a body {error: "Error statement", stack: "..."}
Before, it was status 500 with a plain text stack including ArangoDB internal routing information.
* The Applications tab in web interface will now request development apps more often.
So if you have a fixed a syntax error in your app it should always be visible after reload.
v2.4.1 (2015-01-19)
-------------------
* improved WAL recovery output
* fixed certain OR optimizations in AQL optimizer
* better diagnostics for arangoimp
* fixed invalid result of HTTP REST API method `/_admin/foxx/rescan`
* fixed possible segmentation fault when passing a Buffer object into a V8 function
as a parameter
* updated AQB module to 1.8.0.
v2.4.0 (2015-01-13)
-------------------
* updated AQB module to 1.7.0.
* fixed V8 integration-related crashes
* make `fs.move(src, dest)` also fail when both `src` and `dest` are
existing directories. This ensures the same behavior of the move operation
on different platforms.
* fixed AQL insert operation for multi-shard collections in cluster
* added optional return value for AQL data-modification queries.
This allows returning the documents inserted, removed or updated with the query, e.g.
FOR doc IN docs REMOVE doc._key IN docs LET removed = OLD RETURN removed
FOR doc IN docs INSERT { } IN docs LET inserted = NEW RETURN inserted
FOR doc IN docs UPDATE doc._key WITH { } IN docs LET previous = OLD RETURN previous
FOR doc IN docs UPDATE doc._key WITH { } IN docs LET updated = NEW RETURN updated
The variables `OLD` and `NEW` are automatically available when a `REMOVE`, `INSERT`,
`UPDATE` or `REPLACE` statement is immediately followed by a `LET` statement.
Note that the `LET` and `RETURN` statements in data-modification queries are not as
flexible as the general versions of `LET` and `RETURN`. When returning documents from
data-modification operations, only a single variable can be assigned using `LET`, and
the assignment can only be either `OLD` or `NEW`, but not an arbitrary expression. The
`RETURN` statement also allows using the just-created variable only, and no arbitrary
expressions.
v2.4.0-beta1 (2014-12-26)
--------------------------
* fixed superstates in FoxxGenerator
* fixed issue #1065: Aardvark: added creation of documents and edges with _key property
* fixed issue #1198: Aardvark: current AQL editor query is now cached
* Upgraded V8 version from 3.16.14 to 3.29.59
The built-in version of V8 has been upgraded from 3.16.14 to 3.29.59.
This activates several ES6 (also dubbed *Harmony* or *ES.next*) features in
ArangoDB, both in the ArangoShell and the ArangoDB server. They can be
used for scripting and in server-side actions such as Foxx routes, traversals
etc.
The following ES6 features are available in ArangoDB 2.4 by default:
* iterators
* the `of` operator
* symbols
* predefined collections types (Map, Set etc.)
* typed arrays
Many other ES6 features are disabled by default, but can be made available by
starting arangod or arangosh with the appropriate options:
* arrow functions
* proxies
* generators
* String, Array, and Number enhancements
* constants
* enhanced object and numeric literals
To activate all these ES6 features in arangod or arangosh, start it with
the following options:
arangosh --javascript.v8-options="--harmony --harmony_generators"
More details on the available ES6 features can be found in
[this blog](https://jsteemann.github.io/blog/2014/12/19/using-es6-features-in-arangodb/).
* Added Foxx generator for building Hypermedia APIs
A more detailed description is [here](https://www.arangodb.com/2014/12/08/building-hypermedia-apis-foxxgenerator)
* New `Applications` tab in web interface:
The `applications` tab got a complete redesign.
It will now only show applications that are currently running on ArangoDB.
For a selected application, a new detailed view has been created.
This view provides a better overview of the app:
* author
* license
* version
* contributors
* download links
* API documentation
To install a new application, a new dialogue is now available.
It provides the features already available in the console application `foxx-manager` plus some more:
* install an application from Github
* install an application from a zip file
* install an application from ArangoDB's application store
* create a new application from scratch: this feature uses a generator to
create a Foxx application with pre-defined CRUD methods for a given list
of collections. The generated Foxx app can either be downloaded as a zip file or
be installed on the server. Starting with a new Foxx app has never been easier.
* fixed issue #1102: Aardvark: Layout bug in documents overview
The documents overview was entirely destroyed in some situations on Firefox.
We replaced the plugin we used there.
* fixed issue #1168: Aardvark: pagination buttons jumping
* fixed issue #1161: Aardvark: Click on Import JSON imports previously uploaded file
* removed configure options `--enable-all-in-one-v8`, `--enable-all-in-one-icu`,
and `--enable-all-in-one-libev`.
* global internal rename to fix naming incompatibilities with JSON:
Internal functions with names containing `array` have been renamed to `object`,
internal functions with names containing `list` have been renamed to `array`.
The renaming was mainly done in the C++ parts. The documentation has also been
adjusted so that the correct JSON type names are used in most places.
The change also led to the addition of a few function aliases in AQL:
* `TO_LIST` now is an alias of the new `TO_ARRAY`
* `IS_LIST` now is an alias of the new `IS_ARRAY`
* `IS_DOCUMENT` now is an alias of the new `IS_OBJECT`
The changed also renamed the option `mergeArrays` to `mergeObjects` for AQL
data-modification query options and HTTP document modification API
* AQL: added optimizer rule "remove-filter-covered-by-index"
This rule removes FilterNodes and CalculationNodes from an execution plan if the
filter is already covered by a previous IndexRangeNode. Removing the CalculationNode
and the FilterNode will speed up query execution because the query requires less
computation.
* AQL: added optimizer rule "remove-sort-rand"
This rule removes a `SORT RAND()` expression from a query and moves the random
iteration into the appropriate `EnumerateCollectionNode`. This is more efficient
than individually enumerating and then sorting randomly.
* AQL: range optimizations for IN and OR
This change enables usage of indexes for several additional cases. Filters containing
the `IN` operator can now make use of indexes, and multiple OR- or AND-combined filter
conditions can now also use indexes if the filters are accessing the same indexed
attribute.
Here are a few examples of queries that can now use indexes but couldn't before:
FOR doc IN collection
FILTER doc.indexedAttribute == 1 || doc.indexedAttribute > 99
RETURN doc
FOR doc IN collection
FILTER doc.indexedAttribute IN [ 3, 42 ] || doc.indexedAttribute > 99
RETURN doc
FOR doc IN collection
FILTER (doc.indexedAttribute > 2 && doc.indexedAttribute < 10) ||
(doc.indexedAttribute > 23 && doc.indexedAttribute < 42)
RETURN doc
* fixed issue #500: AQL parentheses issue
This change allows passing subqueries as AQL function parameters without using
duplicate brackets (e.g. `FUNC(query)` instead of `FUNC((query))`
* added optional `COUNT` clause to AQL `COLLECT`
This allows more efficient group count calculation queries, e.g.
FOR doc IN collection
COLLECT age = doc.age WITH COUNT INTO length
RETURN { age: age, count: length }
A count-only query is also possible:
FOR doc IN collection
COLLECT WITH COUNT INTO length
RETURN length
* fixed missing makeDirectory when fetching a Foxx application from a zip file
* fixed issue #1134: Change the default endpoint to localhost
This change will modify the IP address ArangoDB listens on to 127.0.0.1 by default.
This will make new ArangoDB installations unaccessible from clients other than
localhost unless changed. This is a security feature.
To make ArangoDB accessible from any client, change the server's configuration
(`--server.endpoint`) to either `tcp://0.0.0.0:8529` or the server's publicly
visible IP address.
* deprecated `Repository#modelPrototype`. Use `Repository#model` instead.
* IMPORTANT CHANGE: by default, system collections are included in replication and all
replication API return values. This will lead to user accounts and credentials
data being replicated from master to slave servers. This may overwrite
slave-specific database users.
If this is undesired, the `_users` collection can be excluded from replication
easily by setting the `includeSystem` attribute to `false` in the following commands:
* replication.sync({ includeSystem: false });
* replication.applier.properties({ includeSystem: false });
This will exclude all system collections (including `_aqlfunctions`, `_graphs` etc.)
from the initial synchronisation and the continuous replication.
If this is also undesired, it is also possible to specify a list of collections to
exclude from the initial synchronisation and the continuous replication using the
`restrictCollections` attribute, e.g.:
replication.applier.properties({
includeSystem: true,
restrictType: "exclude",
restrictCollections: [ "_users", "_graphs", "foo" ]
});
The HTTP API methods for fetching the replication inventory and for dumping collections
also support the `includeSystem` control flag via a URL parameter.
* removed DEPRECATED replication methods:
* `replication.logger.start()`
* `replication.logger.stop()`
* `replication.logger.properties()`
* HTTP PUT `/_api/replication/logger-start`
* HTTP PUT `/_api/replication/logger-stop`
* HTTP GET `/_api/replication/logger-config`
* HTTP PUT `/_api/replication/logger-config`
* fixed issue #1174, which was due to locking problems in distributed
AQL execution
* improved cluster locking for AQL avoiding deadlocks
* use DistributeNode for modifying queries with REPLACE and UPDATE, if
possible
v2.3.6 (2015-XX-XX)
-------------------
* fixed AQL subquery optimization that produced wrong result when multiple subqueries
directly followed each other and and a directly following `LET` statement did refer
to any but the first subquery.
v2.3.5 (2015-01-16)
-------------------
* fixed intermittent 404 errors in Foxx apps after mounting or unmounting apps
* fixed issue #1200: Expansion operator results in "Cannot call method 'forEach' of null"
* fixed issue #1199: Cannot unlink root node of plan
v2.3.4 (2014-12-23)
-------------------
* fixed cerberus path for MyArangoDB
v2.3.3 (2014-12-17)
-------------------
* fixed error handling in instanciation of distributed AQL queries, this
also fixes a bug in cluster startup with many servers
* issue #1185: parse non-fractional JSON numbers with exponent (e.g. `4e-261`)
* issue #1159: allow --server.request-timeout and --server.connect-timeout of 0
v2.3.2 (2014-12-09)
-------------------
* fixed issue #1177: Fix bug in the user app's storage
* fixed issue #1173: AQL Editor "Save current query" resets user password
* fixed missing makeDirectory when fetching a Foxx application from a zip file
* put in warning about default changed: fixed issue #1134: Change the default endpoint to localhost
* fixed issue #1163: invalid fullCount value returned from AQL
* fixed range operator precedence
* limit default maximum number of plans created by AQL optimizer to 256 (from 1024)
* make AQL optimizer not generate an extra plan if an index can be used, but modify
existing plans in place
* fixed AQL cursor ttl (time-to-live) issue
Any user-specified cursor ttl value was not honored since 2.3.0.
* fixed segfault in AQL query hash index setup with unknown shapes
* fixed memleaks
* added AQL optimizer rule for removing `INTO` from a `COLLECT` statement if not needed
* fixed issue #1131
This change provides the `KEEP` clause for `COLLECT ... INTO`. The `KEEP` clause
allows controlling which variables will be kept in the variable created by `INTO`.
* fixed issue #1147, must protect dispatcher ID for etcd
v2.3.1 (2014-11-28)
-------------------
* recreate password if missing during upgrade
* fixed issue #1126
* fixed non-working subquery index optimizations
* do not restrict summary of Foxx applications to 60 characters
* fixed display of "required" path parameters in Foxx application documentation
* added more optimizations of constants values in AQL FILTER conditions
* fixed invalid or-to-in optimization for FILTERs containing comparisons
with boolean values
* fixed replication of `_graphs` collection
* added AQL list functions `PUSH`, `POP`, `UNSHIFT`, `SHIFT`, `REMOVE_VALUES`,
`REMOVE_VALUE`, `REMOVE_NTH` and `APPEND`
* added AQL functions `CALL` and `APPLY` to dynamically call other functions
* fixed AQL optimizer cost estimation for LIMIT node
* prevent Foxx queues from permanently writing to the journal even when
server is idle
* fixed AQL COLLECT statement with INTO clause, which copied more variables
than v2.2 and thus lead to too much memory consumption.
This deals with #1107.
* fixed AQL COLLECT statement, this concerned every COLLECT statement,
only the first group had access to the values of the variables before
the COLLECT statement. This deals with #1127.
* fixed some AQL internals, where sometimes too many items were
fetched from upstream in the presence of a LIMIT clause. This should
generally improve performance.
v2.3.0 (2014-11-18)
-------------------
* fixed syslog flags. `--log.syslog` is deprecated and setting it has no effect,
`--log.facility` now works as described. Application name has been changed from
`triagens` to `arangod`. It can be changed using `--log.application`. The syslog
will only contain the actual log message. The datetime prefix is omiited.
* fixed deflate in SimpleHttpClient
* fixed issue #1104: edgeExamples broken or changed
* fixed issue #1103: Error while importing user queries
* fixed issue #1100: AQL: HAS() fails on doc[attribute_name]
* fixed issue #1098: runtime error when creating graph vertex
* hide system applications in **Applications** tab by default
Display of system applications can be toggled by using the *system applications*
toggle in the UI.
* added HTTP REST API for managing tasks (`/_api/tasks`)
* allow passing character lists as optional parameter to AQL functions `TRIM`,
`LTRIM` and `RTRIM`
These functions now support trimming using custom character lists. If no character
lists are specified, all whitespace characters will be removed as previously:
TRIM(" foobar\t \r\n ") // "foobar"
TRIM(";foo;bar;baz, ", "; ") // "foo;bar;baz"
* added AQL string functions `LTRIM`, `RTRIM`, `FIND_FIRST`, `FIND_LAST`, `SPLIT`,
`SUBSTITUTE`
* added AQL functions `ZIP`, `VALUES` and `PERCENTILE`
* made AQL functions `CONCAT` and `CONCAT_SEPARATOR` work with list arguments
* dynamically create extra dispatcher threads if required
* fixed issue #1097: schemas in the API docs no longer show required properties as optional
v2.3.0-beta2 (2014-11-08)
-------------------------
* front-end: new icons for uploading and downloading JSON documents into a collection
* front-end: fixed documents pagination css display error
* front-end: fixed flickering of the progress view
* front-end: fixed missing event for documents filter function
* front-end: jsoneditor: added CMD+Return (Mac) CTRL+Return (Linux/Win) shortkey for
saving a document
* front-end: added information tooltip for uploading json documents.
* front-end: added database management view to the collapsed navigation menu
* front-end: added collection truncation feature
* fixed issue #1086: arangoimp: Odd errors if arguments are not given properly
* performance improvements for AQL queries that use JavaScript-based expressions
internally
* added AQL geo functions `WITHIN_RECTANGLE` and `IS_IN_POLYGON`
* fixed non-working query results download in AQL editor of web interface
* removed debug print message in AQL editor query export routine
* fixed issue #1075: Aardvark: user name required even if auth is off #1075
The fix for this prefills the username input field with the current user's
accout name if any and `root` (the default username) otherwise. Additionally,
the tooltip text has been slightly adjusted.
* fixed issue #1069: Add 'raw' link to swagger ui so that the raw swagger
json can easily be retrieved
This adds a link to the Swagger API docs to an application's detail view in
the **Applications** tab of the web interface. The link produces the Swagger
JSON directly. If authentication is turned on, the link requires authentication,
too.
* documentation updates
v2.3.0-beta1 (2014-11-01)
-------------------------
* added dedicated `NOT IN` operator for AQL
Previously, a `NOT IN` was only achievable by writing a negated `IN` condition:
FOR i IN ... FILTER ! (i IN [ 23, 42 ]) ...
This can now alternatively be expressed more intuitively as follows:
FOR i IN ... FILTER i NOT IN [ 23, 42 ] ...
* added alternative logical operator syntax for AQL
Previously, the logical operators in AQL could only be written as:
- `&&`: logical and
- `||`: logical or
- `!`: negation
ArangoDB 2.3 introduces the alternative variants for these operators:
- `AND`: logical and
- `OR`: logical or
- `NOT`: negation
The new syntax is just an alternative to the old syntax, allowing easier
migration from SQL. The old syntax is still fully supported and will be.
* improved output of `ArangoStatement.parse()` and POST `/_api/query`
If an AQL query can be parsed without problems, The return value of
`ArangoStatement.parse()` now contains an attribute `ast` with the abstract
syntax tree of the query (before optimizations). Though this is an internal
representation of the query and is subject to change, it can be used to inspect
how ArangoDB interprets a given query.
* improved `ArangoStatement.explain()` and POST `/_api/explain`
The commands for explaining AQL queries have been improved.
* added command-line option `--javascript.v8-contexts` to control the number of
V8 contexts created in arangod.
Previously, the number of V8 contexts was equal to the number of server threads
(as specified by option `--server.threads`).
However, it may be sensible to create different amounts of threads and V8
contexts. If the option is not specified, the number of V8 contexts created
will be equal to the number of server threads. Thus no change in configuration
is required to keep the old behavior.
If you are using the default config files or merge them with your local config
files, please review if the default number of server threads is okay in your
environment. Additionally you should verify that the number of V8 contexts
created (as specified in option `--javascript.v8-contexts`) is okay.
* the number of server.threads specified is now the minimum of threads
started. There are situation in which threads are waiting for results of
distributed database servers. In this case the number of threads is
dynamically increased.
* removed index type "bitarray"
Bitarray indexes were only half-way documented and integrated in previous versions
of ArangoDB so their benefit was limited. The support for bitarray indexes has
thus been removed in ArangoDB 2.3. It is not possible to create indexes of type
"bitarray" with ArangoDB 2.3.
When a collection is openend that contains a bitarray index definition created
with a previous version of ArangoDB, ArangoDB will ignore it and log the following
warning:
index type 'bitarray' is not supported in this version of ArangoDB and is ignored
Future versions of ArangoDB may automatically remove such index definitions so the
warnings will eventually disappear.
* removed internal "_admin/modules/flush" in order to fix requireApp
* added basic support for handling binary data in Foxx
Requests with binary payload can be processed in Foxx applications by
using the new method `res.rawBodyBuffer()`. This will return the unparsed request
body as a Buffer object.
There is now also the method `req.requestParts()` available in Foxx to retrieve
the individual components of a multipart HTTP request.
Buffer objects can now be used when setting the response body of any Foxx action.
Additionally, `res.send()` has been added as a convenience method for returning
strings, JSON objects or buffers from a Foxx action:
res.send("<p>some HTML</p>");
res.send({ success: true });
res.send(new Buffer("some binary data"));
The convenience method `res.sendFile()` can now be used to easily return the
contents of a file from a Foxx action:
res.sendFile(applicationContext.foxxFilename("image.png"));
`fs.write` now accepts not only strings but also Buffer objects as second parameter:
fs.write(filename, "some data");
fs.write(filename, new Buffer("some binary data"));
`fs.readBuffer` can be used to return the contents of a file in a Buffer object.
* improved performance of insertion into non-unique hash indexes significantly in case
many duplicate keys are used in the index
* issue #1042: set time zone in log output
the command-line option `--log.use-local-time` was added to print dates and times in
the server-local timezone instead of UTC
* command-line options that require a boolean value now validate the
value given on the command-line
This prevents issues if no value is specified for an option that
requires a boolean value. For example, the following command-line would
have caused trouble in 2.2, because `--server.endpoint` would have been
used as the value for the `--server.disable-authentication` options
(which requires a boolean value):
arangod --server.disable-authentication --server.endpoint tcp://127.0.0.1:8529 data
In 2.3, running this command will fail with an error and requires to
be modified to:
arangod --server.disable-authentication true --server.endpoint tcp://127.0.0.1:8529 data
* improved performance of CSV import in arangoimp
* fixed issue #1027: Stack traces are off-by-one
* fixed issue #1026: Modules loaded in different files within the same app
should refer to the same module
* fixed issue #1025: Traversal not as expected in undirected graph
* added a _relation function in the general-graph module.
This deprecated _directedRelation and _undirectedRelation.
ArangoDB does not offer any constraints for undirected edges
which caused some confusion of users how undirected relations
have to be handled. Relation now only supports directed relations
and the user can actively simulate undirected relations.
* changed return value of Foxx.applicationContext#collectionName:
Previously, the function could return invalid collection names because
invalid characters were not replaced in the application name prefix, only
in the collection name passed.
Now, the function replaces invalid characters also in the application name
prefix, which might to slightly different results for application names that
contained any characters outside the ranges [a-z], [A-Z] and [0-9].
* prevent XSS in AQL editor and logs view
* integrated tutorial into ArangoShell and web interface
* added option `--backslash-escape` for arangoimp when running CSV file imports
* front-end: added download feature for (filtered) documents
* front-end: added download feature for the results of a user query
* front-end: added function to move documents to another collection
* front-end: added sort-by attribute to the documents filter
* front-end: added sorting feature to database, graph management and user management view.
* issue #989: front-end: Databases view not refreshing after deleting a database
* issue #991: front-end: Database search broken
* front-end: added infobox which shows more information about a document (_id, _rev, _key) or
an edge (_id, _rev, _key, _from, _to). The from and to attributes are clickable and redirect
to their document location.
* front-end: added edit-mode for deleting multiple documents at the same time.
* front-end: added delete button to the detailed document/edge view.
* front-end: added visual feedback for saving documents/edges inside the editor (error/success).
* front-end: added auto-focusing for the first input field in a modal.
* front-end: added validation for user input in a modal.
* front-end: user defined queries are now stored inside the database and are bound to the current
user, instead of using the local storage functionality of the browsers. The outcome of this is
that user defined queries are now independently usable from any device. Also queries can now be
edited through the standard document editor of the front-end through the _users collection.
* front-end: added import and export functionality for user defined queries.
* front-end: added new keywords and functions to the aql-editor theme
* front-end: applied tile-style to the graph view
* front-end: now using the new graph api including multi-collection support
* front-end: foxx apps are now deleteable
* front-end: foxx apps are now installable and updateable through github, if github is their
origin.
* front-end: added foxx app version control. Multiple versions of a single foxx app are now
installable and easy to manage and are also arranged in groups.
* front-end: the user-set filter of a collection is now stored until the user navigates to
another collection.
* front-end: fetching and filtering of documents, statistics, and query operations are now
handled with asynchronous ajax calls.
* front-end: added progress indicator if the front-end is waiting for a server operation.
* front-end: fixed wrong count of documents in the documents view of a collection.
* front-end: fixed unexpected styling of the manage db view and navigation.
* front-end: fixed wrong handling of select fields in a modal view.
* front-end: fixed wrong positioning of some tooltips.
* automatically call `toJSON` function of JavaScript objects (if present)
when serializing them into database documents. This change allows
storing JavaScript date objects in the database in a sensible manner.
v2.2.7 (2014-11-19)
-------------------
* fixed issue #998: Incorrect application URL for non-system Foxx apps
* fixed issue #1079: AQL editor: keyword WITH in UPDATE query is not highlighted
* fix memory leak in cluster nodes
* fixed registration of AQL user-defined functions in Web UI (JS shell)
* fixed error display in Web UI for certain errors
(now error message is printed instead of 'undefined')
* fixed issue #1059: bug in js module console
* fixed issue #1056: "fs": zip functions fail with passwords
* fixed issue #1063: Docs: measuring unit of --wal.logfile-size?
* fixed issue #1062: Docs: typo in 14.2 Example data
v2.2.6 (2014-10-20)
-------------------
* fixed issue #972: Compilation Issue
* fixed issue #743: temporary directories are now unique and one can read
off the tool that created them, if empty, they are removed atexit
* Highly improved performance of all AQL GRAPH_* functions.
* Orphan collections in general graphs can now be found via GRAPH_VERTICES
if either "any" or no direction is defined
* Fixed documentation for AQL function GRAPH_NEIGHBORS.
The option "vertexCollectionRestriction" is meant to filter the target
vertices only, and should not filter the path.
* Fixed a bug in GRAPH_NEIGHBORS which enforced only empty results
under certain conditions
v2.2.5 (2014-10-09)
-------------------
* fixed issue #961: allow non-JSON values in undocument request bodies
* fixed issue 1028: libicu is now statically linked
* fixed cached lookups of collections on the server, which may have caused spurious
problems after collection rename operations
v2.2.4 (2014-10-01)
-------------------
* fixed accessing `_from` and `_to` attributes in `collection.byExample` and
`collection.firstExample`
These internal attributes were not handled properly in the mentioned functions, so
searching for them did not always produce documents
* fixed issue #1030: arangoimp 2.2.3 crashing, not logging on large Windows CSV file
* fixed issue #1025: Traversal not as expected in undirected graph
* fixed issue #1020
This requires re-introducing the startup option `--database.force-sync-properties`.
This option can again be used to force fsyncs of collection, index and database properties
stored as JSON strings on disk in files named `parameter.json`. Syncing these files after
a write may be necessary if the underlying storage does not sync file contents by itself
in a "sensible" amount of time after a file has been written and closed.
The default value is `true` so collection, index and database properties will always be
synced to disk immediately. This affects creating, renaming and dropping collections as
well as creating and dropping databases and indexes. Each of these operations will perform
an additional fsync on the `parameter.json` file if the option is set to `true`.
It might be sensible to set this option to `false` for workloads that create and drop a
lot of collections (e.g. test runs).
Document operations such as creating, updating and dropping documents are not affected
by this option.
* fixed issue #1016: AQL editor bug
* fixed issue #1014: WITHIN function returns wrong distance
* fixed AQL shortest path calculation in function `GRAPH_SHORTEST_PATH` to return
complete vertex objects instead of just vertex ids
* allow changing of attributes of documents stored in server-side JavaScript variables
Previously, the following did not work:
var doc = db.collection.document(key);
doc._key = "abc"; // overwriting internal attributes not supported
doc.value = 123; // overwriting existing attributes not supported
Now, modifying documents stored in server-side variables (e.g. `doc` in the above case)
is supported. Modifying the variables will not update the documents in the database,
but will modify the JavaScript object (which can be written back to the database using
`db.collection.update` or `db.collection.replace`)
* fixed issue #997: arangoimp apparently doesn't support files >2gig on Windows
large file support (requires using `_stat64` instead of `stat`) is now supported on
Windows
v2.2.3 (2014-09-02)
-------------------
* added `around` for Foxx controller
* added `type` option for HTTP API `GET /_api/document?collection=...`
This allows controlling the type of results to be returned. By default, paths to
documents will be returned, e.g.
[
`/_api/document/test/mykey1`,
`/_api/document/test/mykey2`,
...
]
To return a list of document ids instead of paths, the `type` URL parameter can be
set to `id`:
[
`test/mykey1`,
`test/mykey2`,
...
]
To return a list of document keys only, the `type` URL parameter can be set to `key`:
[
`mykey1`,
`mykey2`,
...
]
* properly capitalize HTTP response header field names in case the `x-arango-async`
HTTP header was used in a request.
* fixed several documentation issues
* speedup for several general-graph functions, AQL functions starting with `GRAPH_`
and traversals
v2.2.2 (2014-08-08)
-------------------
* allow storing non-reserved attribute names starting with an underscore
Previous versions of ArangoDB parsed away all attribute names that started with an
underscore (e.g. `_test', '_foo', `_bar`) on all levels of a document (root level
and sub-attribute levels). While this behavior was documented, it was unintuitive and
prevented storing documents inside other documents, e.g.:
{
"_key" : "foo",
"_type" : "mydoc",
"references" : [
{
"_key" : "something",
"_rev" : "...",
"value" : 1
},
{
"_key" : "something else",
"_rev" : "...",
"value" : 2
}
]
}
In the above example, previous versions of ArangoDB removed all attributes and
sub-attributes that started with underscores, meaning the embedded documents would lose
some of their attributes. 2.2.2 should preserve such attributes, and will also allow
storing user-defined attribute names on the top-level even if they start with underscores
(such as `_type` in the above example).
* fix conversion of JavaScript String, Number and Boolean objects to JSON.
Objects created in JavaScript using `new Number(...)`, `new String(...)`, or
`new Boolean(...)` were not converted to JSON correctly.
* fixed a race condition on task registration (i.e. `require("org/arangodb/tasks").register()`)
this race condition led to undefined behavior when a just-created task with no offset and
no period was instantly executed and deleted by the task scheduler, before the `register`
function returned to the caller.
* changed run-tests.sh to execute all suitable tests.
* switch to new version of gyp
* fixed upgrade button
v2.2.1 (2014-07-24)
-------------------
* fixed hanging write-ahead log recovery for certain cases that involved dropping
databases
* fixed issue with --check-version: when creating a new database the check failed
* issue #947 Foxx applicationContext missing some properties
* fixed issue with --check-version: when creating a new database the check failed
* added startup option `--wal.suppress-shape-information`
