This information can be used for debugging compaction and unload issues. - `waitingFor`: An optional string value that contains information about which object type is at the head of the collection's cleanup queue. This information can be used for debugging compaction and unload issues. - `compactionStatus.time`: The point in time the compaction for the collection was last executed. This information can be used for debugging compaction issues. - `compactionStatus.message`: The action that was performed when the compaction was last run for the collection. This information can be used for debugging compaction issues. Note: `waitingFor` and `compactionStatus` may be empty when called on a coordinator in a cluster. * the compaction will now provide queryable status info that can be used to track its progress. The compaction status is displayed in the web interface, too. -- ArangoDB Maintainer Mon, 21 Dec 2015 16:10:00 +0000 arangodb (2.7.3-1.1) stable; urgency=low * Changed to Version 2.7.3 * fixed disappearing of documents for collections transferred via `sync` or `syncCollection` if the collection was dropped right before synchronization and drop and (re-)create collection markers were located in the same WAL file * Foxx: moved Model and Repository back to non-ES6 "classes" * fixed an issue where overwriting the system sessions collection would break the web interface when authentication is enabled -- ArangoDB Maintainer Thu, 17 Dec 2015 15:37:54 +0000 arangodb (2.7.2-1.1) stable; urgency=low * Changed to Version 2.7.2 * replication improvements: - added `autoResync` configuration parameter for continuous replication. When set to `true`, a replication slave will automatically trigger a full data re-synchronization with the master when the master cannot provide the log data the slave had asked for. Note that `autoResync` will only work when the option `requireFromPresent` is also set to `true` for the continuous replication, or when the continuous syncer is started and detects that no start tick is present. Automatic re-synchronization may transfer a lot of data from the master to the slave and may be expensive. It is therefore turned off by default. When turned off, the slave will never perform an automatic re-synchronization with the master. - added `idleMinWaitTime` and `idleMaxWaitTime` configuration parameters for continuous replication. These parameters can be used to control the minimum and maximum wait time the slave will (intentionally) idle and not poll for master log changes in case the master had sent the full logs already. The `idleMaxWaitTime` value will only be used when `adapativePolling` is set to `true`. When `adaptivePolling` is disable, only `idleMinWaitTime` will be used as a constant time span in which the slave will not poll the master for further changes. The default values are 0.5 seconds for `idleMinWaitTime` and 2.5 seconds for `idleMaxWaitTime`, which correspond to the hard-coded values used in previous versions of ArangoDB. - added `initialSyncMaxWaitTime` configuration parameter for initial and continuous replication This option controls the maximum wait time (in seconds) that the initial synchronization will wait for a response from the master when fetching initial collection data. If no response is received within this time period, the initial synchronization will give up and fail. This option is also relevant for continuous replication in case *autoResync* is set to *true*, as then the continuous replication may trigger a full data re-synchronization in case the master cannot the log data the slave had asked for. - HTTP requests sent from the slave to the master during initial synchronization will now be retried if they fail with connection problems. - the initial synchronization now logs its progress so it can be queried using the regular replication status check APIs. * fixed non-deterministic query results in some cluster queries * added missing lock instruction for primary index in compactor size calculation * fixed issue #1589 * fixed issue #1583 * fixed undefined behavior when accessing the top level of a document with the `[*]` operator * fixed potentially invalid pointer access in shaper when the currently accessed document got re-located by the WAL collector at the very same time * Foxx: optional configuration options no longer log validation errors when assigned empty values (#1495) * Foxx: constructors provided to Repository and Model sub-classes via extend are now correctly called (#1592) * Foxx: services generated with the admin frontend now use unambiguous require paths.

When replicating data from the master to the slave, the data from the master may clash with the slave's own data in the `_apps` collection. Excluding the `_apps` collection from replication avoids this. * disable replication appliers when starting in modes `--upgrade`, `--no-server` and `--check-upgrade` * more detailed output in arango-dfdb * fixed "no start tick" issue in replication applier This error could occur after restarting a slave server after a shutdown when no data was ever transferred from the master to the slave via the continuous replication * fixed problem during SSL client connection abort that led to scheduler thread staying at 100% CPU saturation * fixed potential segfault in AQL `NEIGHBORS` function implementation when C++ function -- ArangoDB Maintainer Sun, 08 Nov 2015 10:11:14 +0000 arangodb (2.7.0-1.1) stable; urgency=low * Changed to Version 2.7.0 * fixed replication with a 2.6 replication configuration and issues with a 2.6 master * raised default value of `--server.descriptors-minimum` to 1024 * allow Foxx apps to be installed underneath URL path `/_open/`, so they can be (intentionally) accessed without authentication. * added *allowImplicit* sub-attribute in collections declaration of transactions.

It should also prevent from re-compacting already merged datafiles in case not many changes were made. Compaction will also make fewer index lookups than before. * added `syncCollection()` function in module `org/arangodb/replication` This allows synchronizing the data of a single collection from a master to a slave server. Synchronization can either restore the whole collection by transferring all documents from the master to the slave, or incrementally by only transferring documents that differ. This is done by partitioning the collection's entire key space into smaller chunks and comparing the data chunk-wise between master and slave. Only chunks that are different will be re-transferred. The `syncCollection()` function can be used as follows: require("org/arangodb/replication").syncCollection(collectionName, options); e.g. require("org/arangodb/replication").syncCollection("myCollection", { endpoint: "tcp://127.0.0.1:8529", /* master */ username: "root", /* username for master */ password: "secret", /* password for master */ incremental: true /* use incremental mode */ }); * additionally allow the following characters in document keys: `(` `)` `+` `,` `=` `;` `$` `!` `*` `'` `%` * added extra AQL functions for date and time calculation and manipulation. These functions were contributed by GitHub users @CoDEmanX and @friday. A big thanks for their work! The following extra date functions are available from 2.7 on: * `DATE_DAYOFYEAR(date)`: Returns the day of year number of *date*. The return values range from 1 to 365, or 366 in a leap year respectively. * `DATE_ISOWEEK(date)`: Returns the ISO week date of *date*. The return values range from 1 to 53. Monday is considered the first day of the week. There are no fractional weeks, thus the last days in December may belong to the first week of the next year, and the first days in January may be part of the previous year's last week. * `DATE_LEAPYEAR(date)`: Returns whether the year of *date* is a leap year. * `DATE_QUARTER(date)`: Returns the quarter of the given date (1-based): * 1: January, February, March * 2: April, May, June * 3: July, August, September * 4: October, November, December - *DATE_DAYS_IN_MONTH(date)*: Returns the number of days in *date*'s month (28..31). * `DATE_ADD(date, amount, unit)`: Adds *amount* given in *unit* to *date* and returns the calculated date. *unit* can be either of the following to specify the time unit to add or subtract (case-insensitive): - y, year, years - m, month, months - w, week, weeks - d, day, days - h, hour, hours - i, minute, minutes - s, second, seconds - f, millisecond, milliseconds *amount* is the number of *unit*s to add (positive value) or subtract (negative value). * `DATE_SUBTRACT(date, amount, unit)`: Subtracts *amount* given in *unit* from *date* and returns the calculated date. It works the same as `DATE_ADD()`, except that it subtracts. It is equivalent to calling `DATE_ADD()` with a negative amount, except that `DATE_SUBTRACT()` can also subtract ISO durations. Note that negative ISO durations are not supported (i.e. starting with `-P`, like `-P1Y`). * `DATE_DIFF(date1, date2, unit, asFloat)`: Calculate the difference between two dates in given time *unit*, optionally with decimal places. Returns a negative value if *date1* is greater than *date2*. * `DATE_COMPARE(date1, date2, unitRangeStart, unitRangeEnd)`: Compare two partial dates and return true if they match, false otherwise. The parts to compare are defined by a range of time units. The full range is: years, months, days, hours, minutes, seconds, milliseconds. Pass the unit to start from as *unitRangeStart*, and the unit to end with as *unitRangeEnd*. All units in between will be compared. Leave out *unitRangeEnd* to only compare *unitRangeStart*. * `DATE_FORMAT(date, format)`: Format a date according to the given format string. It supports the following placeholders (case-insensitive): - %t: timestamp - %z: ISO date (0000-00-00T00:00:00.000Z) - %w: day of week (0..6) - %y: year (0000..9999) - %m: month (01..12) - %d: day (01..31) - %h: hour (00..23) - %i: minute (00..59) - %s: second (00..59) - %f: millisecond (000..999) - %x: day of year (001..366) - %k: ISO week date (01..53) - %l: leap year (0 or 1) - %q: quarter (1..4) - %a: days in month (28..31) - %n: English name of month (January..December) - %o: abbreviated English name of month (Jan..Dec) - %e: English name of weekday (Sunday..Saturday) - %g: abbreviated English name of weekday (Sun..Sat) - %%: literal % * new WAL logfiles and datafiles are now created non-sparse This prevents SIGBUS signals being raised when memory of a sparse datafile is accessed and the disk is full and the accessed file part is not actually disk-backed.

The only way to access such collection is to use the datafile debugger (arango-dfdb) and try to repair or truncate the datafile with it. If `--database.ignore-datafile-errors` is set to `true`, then collections will become available even if parts of their data cannot be loaded.

So the option pretended to control a lot of things which it actually didn't. Additionally, the option `--log.requests-file` was around for a long time already, also controlling request logging. Because the `--log.severity` option effectively did not control that much, it was removed. A side effect of removing the option is that 2.5 installations which used `--log.severity all` will not log requests after the upgrade to 2.6. This can be adjusted by setting the `--log.requests-file` option. * add backtrace to fatal log events * added optional `limit` parameter for AQL function `FULLTEXT` * make fulltext index also index text values contained in direct sub-objects of the indexed attribute. Previous versions of ArangoDB only indexed the attribute value if it was a string. Sub-attributes of the index attribute were ignored when fulltext indexing. Now, if the index attribute value is an object, the object's values will each be included in the fulltext index if they are strings. If the index attribute value is an array, the array's values will each be included in the fulltext index if they are strings.

If set to `false`, CRC mismatch errors in collection datafiles will lead to a collection not being loaded at all. If a collection needs to be loaded during WAL recovery, the WAL recovery will also abort (if not forced with `--wal.ignore-recovery-errors true`). Setting this flag to `false` protects users from unintentionally using a collection with corrupted datafiles, from which only a subset of the original data can be recovered. If set to `true`, CRC mismatch errors in collection datafiles will lead to the datafile being partially loaded. All data up to until the mismatch will be loaded. This will enable users to continue with a collection datafiles that are corrupted, but will result in only a partial load of the data. The WAL recovery will still abort when encountering a collection with a corrupted datafile, at least if `--wal.ignore-recovery-errors` is not set to `true`. The default value is *true*, so for collections with corrupted datafiles there might be partial data loads once the WAL recovery has finished. If the WAL recovery will need to load a collection with a corrupted datafile, it will still stop when using the default values. * INCOMPATIBLE CHANGE: make the arangod server refuse to start if during startup it finds a non-readable `parameter.json` file for a database or a collection. Stopping the startup process in this case requires manual intervention (fixing the unreadable files), but prevents follow-up errors due to ignored databases or collections from happening. * datafiles and `parameter.json` files written by arangod are now created with read and write privileges for the arangod process user, and with read and write prileges for the arangod process group.

That includes a rewrite of the documentation as well as some code changes as listed below: * Moved Foxx applications to a different folder. The naming convention now is: /_db///APP Before it was: /databases//: This caused some trouble as apps where cached based on name and version and updates did not apply. Hence the path on filesystem and the app's access URL had no relation to one another. Now the path on filesystem is identical to the URL (except for slashes and the appended APP) * Rewrite of Foxx routing The routing of Foxx has been exposed to major internal changes we adjusted because of user feedback. This allows us to set the development mode per mountpoint without having to change pathes and hold apps at seperate locations. * Foxx Development mode The development mode used until 2.4 is gone. It has been replaced by a much more mature version. This includes the deprecation of the javascript.dev-app-path parameter, which is useless since 2.5. Instead of having two separate app directories for production and development, apps now reside in one place, which is used for production as well as for development. Apps can still be put into development mode, changing their behavior compared to production mode. Development mode apps are still reread from disk at every request, and still they ship more debug output. This change has also made the startup options `--javascript.frontend-development-mode` and `--javascript.dev-app-path` obsolete. The former option will not have any effect when set, and the latter option is only read and used during the upgrade to 2.5 and does not have any effects later. * Foxx install process Installing Foxx apps has been a two step process: import them into ArangoDB and mount them at a specific mountpoint. These operations have been joined together. You can install an app at one mountpoint, that's it. No fetch, mount, unmount, purge cycle anymore. The commands have been simplified to just: * install: get your Foxx app up and running * uninstall: shut it down and erase it from disk * Foxx error output Until 2.4 the errors produced by Foxx were not optimal. Often, the error message was just `unable to parse manifest` and contained only an internal stack trace. In 2.5 we made major improvements there, including a much more finegrained error output that helps you debug your Foxx apps. The error message printed is now much closer to its source and should help you track it down. Also we added the default handlers for unhandled errors in Foxx apps: * You will get a nice internal error page whenever your Foxx app is called but was not installed due to any error * You will get a proper error message when having an uncaught error appears in any app route In production mode the messages above will NOT contain any information about your Foxx internals and are safe to be exposed to third party users. In development mode the messages above will contain the stacktrace (if available), making it easier for your in-house devs to track down errors in the application. * added `console` object to Foxx apps. All Foxx apps now have a console object implementing the familiar Console API in their global scope, which can be used to log diagnostic messages to the database. * added `org/arangodb/request` module, which provides a simple API for making HTTP requests to external services. * added optimizer rule `propagate-constant-attributes` This rule will look inside `FILTER` conditions for constant value equality comparisons, and insert the constant values in other places in `FILTER`s. For example, the rule will insert `42` instead of `i.value` in the second `FILTER` of the following query: FOR i IN c1 FOR j IN c2 FILTER i.value == 42 FILTER j.value == i.value RETURN 1 * added `filtered` value to AQL query execution statistics This value indicates how many documents were filtered by `FilterNode`s in the AQL query. Note that `IndexRangeNode`s can also filter documents by selecting only the required ranges from the index. The `filtered` value will not include the work done by `IndexRangeNode`s, but only the work performed by `FilterNode`s. * added support for sparse hash and skiplist indexes Hash and skiplist indexes can optionally be made sparse. Sparse indexes exclude documents in which at least one of the index attributes is either not set or has a value of `null`. As such documents are excluded from sparse indexes, they may contain fewer documents than their non-sparse counterparts. This enables faster indexing and can lead to reduced memory usage in case the indexed attribute does occur only in some, but not all documents of the collection. Sparse indexes will also reduce the number of collisions in non-unique hash indexes in case non-existing or optional attributes are indexed. In order to create a sparse index, an object with the attribute `sparse` can be added to the index creation commands: db.collection.ensureHashIndex(attributeName, { sparse: true }); db.collection.ensureHashIndex(attributeName1, attributeName2, { sparse: true }); db.collection.ensureUniqueConstraint(attributeName, { sparse: true }); db.collection.ensureUniqueConstraint(attributeName1, attributeName2, { sparse: true }); db.collection.ensureSkiplist(attributeName, { sparse: true }); db.collection.ensureSkiplist(attributeName1, attributeName2, { sparse: true }); db.collection.ensureUniqueSkiplist(attributeName, { sparse: true }); db.collection.ensureUniqueSkiplist(attributeName1, attributeName2, { sparse: true }); Note that in place of the above specialized index creation commands, it is recommended to use the more general index creation command `ensureIndex`: ```js db.collection.ensureIndex({ type: "hash", sparse: true, unique: true, fields: [ attributeName ] }); db.collection.ensureIndex({ type: "skiplist", sparse: false, unique: false, fields: [ "a", "b" ] }); ``` When not explicitly set, the `sparse` attribute defaults to `false` for new indexes. This causes a change in behavior when creating a unique hash index without specifying the sparse flag: in 2.4, unique hash indexes were implicitly sparse, always excluding `null` values. There was no option to control this behavior, and sparsity was neither supported for non-unique hash indexes nor skiplists in 2.4. This implicit sparsity of unique hash indexes was considered an inconsistency, and therefore the behavior was cleaned up in 2.5. As of 2.5, indexes will only be created sparse if sparsity is explicitly requested. Existing unique hash indexes from 2.4 or before will automatically be migrated so they are still sparse after the upgrade to 2.5. Geo indexes are implicitly sparse, meaning documents without the indexed location attribute or containing invalid location coordinate values will be excluded from the index automatically. This is also a change when compared to pre-2.5 behavior, when documents with missing or invalid coordinate values may have caused errors on insertion when the geo index' `unique` flag was set and its `ignoreNull` flag was not. This was confusing and has been rectified in 2.5. The method `ensureGeoConstaint()` now does the same as `ensureGeoIndex()`. Furthermore, the attributes `constraint`, `unique`, `ignoreNull` and `sparse` flags are now completely ignored when creating geo indexes. The same is true for fulltext indexes. There is no need to specify non-uniqueness or sparsity for geo or fulltext indexes. They will always be non-unique and sparse. As sparse indexes may exclude some documents, they cannot be used for every type of query. Sparse hash indexes cannot be used to find documents for which at least one of the indexed attributes has a value of `null`. For example, the following AQL query cannot use a sparse index, even if one was created on attribute `attr`: FOR doc In collection FILTER doc.attr == null RETURN doc If the lookup value is non-constant, a sparse index may or may not be used, depending on the other types of conditions in the query. If the optimizer can safely determine that the lookup value cannot be `null`, a sparse index may be used. When uncertain, the optimizer will not make use of a sparse index in a query in order to produce correct results. For example, the following queries cannot use a sparse index on `attr` because the optimizer will not know beforehand whether the comparsion values for `doc.attr` will include `null`: FOR doc In collection FILTER doc.attr == SOME_FUNCTION(...) RETURN doc FOR other IN otherCollection FOR doc In collection FILTER doc.attr == other.attr RETURN doc Sparse skiplist indexes can be used for sorting if the optimizer can safely detect that the index range does not include `null` for any of the index attributes. * inspection of AQL data-modification queries will now detect if the data-modification part of the query can run in lockstep with the data retrieval part of the query, or if the data retrieval part must be executed before the data modification can start. Executing the two in lockstep allows using much smaller buffers for intermediate results and starts the actual data-modification operations much earlier than if the two phases were executed seperately. * Allow dynamic attribute names in AQL object literals This allows using arbitrary expressions to construct attribute names in object literals specified in AQL queries. To disambiguate expressions and other unquoted attribute names, dynamic attribute names need to be enclosed in brackets (`[` and `]`). Example: FOR i IN 1..100 RETURN { [ CONCAT('value-of-', i) ] : i } * make AQL optimizer rule "use-index-for-sort" remove sort also in case a non-sorted index (e.g. a hash index) is used for only equality lookups and all sort attributes are covered by the index. Example that does not require an extra sort (needs hash index on `value`): FOR doc IN collection FILTER doc.value == 1 SORT doc.value RETURN doc Another example that does not require an extra sort (with hash index on `value1`, `value2`): FOR doc IN collection FILTER doc.value1 == 1 && doc.value2 == 2 SORT doc.value1, doc.value2 RETURN doc * make AQL optimizer rule "use-index-for-sort" remove sort also in case the sort critieria excludes the left-most index attributes, but the left-most index attributes are used by the index for equality-only lookups. Example that can use the index for sorting (needs skiplist index on `value1`, `value2`): FOR doc IN collection FILTER doc.value1 == 1 SORT doc.value2 RETURN doc * added selectivity estimates for primary index, edge index, and hash index The selectivity estimates are returned by the `GET /_api/index` REST API method in a sub-attribute `selectivityEstimate` for each index that supports it. This attribute will be omitted for indexes that do not provide selectivity estimates. If provided, the selectivity estimate will be a numeric value between 0 and 1. Selectivity estimates will also be reported in the result of `collection.getIndexes()` for all indexes that support this. If no selectivity estimate can be determined for an index, the attribute `selectivityEstimate` will be omitted here, too. The web interface also shows selectivity estimates for each index that supports this. Currently the following index types can provide selectivity estimates: - primary index - edge index - hash index (unique and non-unique) No selectivity estimates will be provided when running in cluster mode. * 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. * Windows service uninstalling: only remove service if it points to the currently running binary, or --force was specified. * Windows (debug only): print stacktraces on crash and run minidump * Windows (cygwin): if you run arangosh in a cygwin shell or via ssh we will detect this and use the appropriate output functions. * Windows: improve process management * fix ipv6 reverse ip lookups - so far we only did ipv4 addresses. * improve join documentation, add outer join example * run jslint for unit tests too, to prevent "memory leaks" by global js objects with native code. * fix error logging for exceptions - we wouldn't log the exception message itself so far. * improve error reporting in the http client (windows & *nix) * improve error reports in cluster * Standard Errors can now contain custom messages. -- ArangoDB Maintainer Tue, 24 Feb 2015 23:30:19 +0100 arangodb (2.5.0b1-1.1) stable; urgency=low * Changed to Version 2.5.0-beta1 * front-end: dashboard tries not to (re)load statistics if user has no access * V8: Upgrade to version 3.31.74.1 * etcd: Upgrade to version 2.0 - This requires go 1.3 to compile at least. * refuse to startup if ICU wasn't initialized, this will i.e. prevent errors from being printed, and libraries from being loaded. * front-end: unwanted removal of index table header after creating new index * fixed issue #1248: chrome: applications filtering not working * fixed issue #1198: queries remain in aql editor (front-end) if you navigate through different tabs * Simplify usage of Foxx Thanks to our user feedback we learned that Foxx is a powerful, yet rather complicated concept.

In order to create a sparse index, an object with the attribute `sparse` can be added to the index creation commands: db.collection.ensureHashIndex(attributeName, { sparse: true }); db.collection.ensureHashIndex(attributeName1, attributeName2, { sparse: true }); db.collection.ensureUniqueConstraint(attributeName, { sparse: true }); db.collection.ensureUniqueConstraint(attributeName1, attributeName2, { sparse: true }); db.collection.ensureSkiplist(attributeName, { sparse: true }); db.collection.ensureSkiplist(attributeName1, attributeName2, { sparse: true }); db.collection.ensureUniqueSkiplist(attributeName, { sparse: true }); db.collection.ensureUniqueSkiplist(attributeName1, attributeName2, { sparse: true }); Note that in place of the above specialized index creation commands, it is recommended to use the more general index creation command `ensureIndex`: ```js db.collection.ensureIndex({ type: "hash", sparse: true, unique: true, fields: [ attributeName ] }); db.collection.ensureIndex({ type: "skiplist", sparse: false, unique: false, fields: [ "a", "b" ] }); ``` When not explicitly set, the `sparse` attribute defaults to `false` for new indexes. This causes a change in behavior when creating a unique hash index without specifying the sparse flag: in 2.4, unique hash indexes were implicitly sparse, always excluding `null` values. There was no option to control this behavior, and sparsity was neither supported for non-unique hash indexes nor skiplists in 2.4. This implicit sparsity of unique hash indexes was considered an inconsistency, and therefore the behavior was cleaned up in 2.5. As of 2.5, indexes will only be created sparse if sparsity is explicitly requested. Existing unique hash indexes from 2.4 or before will automatically be migrated so they are still sparse after the upgrade to 2.5. Geo indexes are implicitly sparse, meaning documents without the indexed location attribute or containing invalid location coordinate values will be excluded from the index automatically. This is also a change when compared to pre-2.5 behavior, when documents with missing or invalid coordinate values may have caused errors on insertion when the geo index' `unique` flag was set and its `ignoreNull` flag was not. This was confusing and has been rectified in 2.5. The method `ensureGeoConstaint()` now does the same as `ensureGeoIndex()`. Furthermore, the attributes `constraint`, `unique`, `ignoreNull` and `sparse` flags are now completely ignored when creating geo indexes. The same is true for fulltext indexes. There is no need to specify non-uniqueness or sparsity for geo or fulltext indexes. They will always be non-unique and sparse. As sparse indexes may exclude some documents, they cannot be used for every type of query. Sparse hash indexes cannot be used to find documents for which at least one of the indexed attributes has a value of `null`. For example, the following AQL query cannot use a sparse index, even if one was created on attribute `attr`: FOR doc In collection FILTER doc.attr == null RETURN doc If the lookup value is non-constant, a sparse index may or may not be used, depending on the other types of conditions in the query. If the optimizer can safely determine that the lookup value cannot be `null`, a sparse index may be used. When uncertain, the optimizer will not make use of a sparse index in a query in order to produce correct results. For example, the following queries cannot use a sparse index on `attr` because the optimizer will not know beforehand whether the comparsion values for `doc.attr` will include `null`: FOR doc In collection FILTER doc.attr == SOME_FUNCTION(...) RETURN doc FOR other IN otherCollection FOR doc In collection FILTER doc.attr == other.attr RETURN doc Sparse skiplist indexes can be used for sorting if the optimizer can safely detect that the index range does not include `null` for any of the index attributes. * inspection of AQL data-modification queries will now detect if the data-modification part of the query can run in lockstep with the data retrieval part of the query, or if the data retrieval part must be executed before the data modification can start. Executing the two in lockstep allows using much smaller buffers for intermediate results and starts the actual data-modification operations much earlier than if the two phases were executed seperately. * Allow dynamic attribute names in AQL object literals This allows using arbitrary expressions to construct attribute names in object literals specified in AQL queries. To disambiguate expressions and other unquoted attribute names, dynamic attribute names need to be enclosed in brackets (`[` and `]`). Example: FOR i IN 1..100 RETURN { [ CONCAT('value-of-', i) ] : i } * make AQL optimizer rule "use-index-for-sort" remove sort also in case a non-sorted index (e.g. a hash index) is used for only equality lookups and all sort attributes are covered by the index. Example that does not require an extra sort (needs hash index on `value`): FOR doc IN collection FILTER doc.value == 1 SORT doc.value RETURN doc Another example that does not require an extra sort (with hash index on `value1`, `value2`): FOR doc IN collection FILTER doc.value1 == 1 && doc.value2 == 2 SORT doc.value1, doc.value2 RETURN doc * make AQL optimizer rule "use-index-for-sort" remove sort also in case the sort critieria excludes the left-most index attributes, but the left-most index attributes are used by the index for equality-only lookups. Example that can use the index for sorting (needs skiplist index on `value1`, `value2`): FOR doc IN collection FILTER doc.value1 == 1 SORT doc.value2 RETURN doc * added selectivity estimates for primary index, edge index, and hash index The selectivity estimates are returned by the `GET /_api/index` REST API method in a sub-attribute `selectivityEstimate` for each index that supports it. This attribute will be omitted for indexes that do not provide selectivity estimates. If provided, the selectivity estimate will be a numeric value between 0 and 1. Selectivity estimates will also be reported in the result of `collection.getIndexes()` for all indexes that support this. If no selectivity estimate can be determined for an index, the attribute `selectivityEstimate` will be omitted here, too. The web interface also shows selectivity estimates for each index that supports this. Currently the following index types can provide selectivity estimates: - primary index - edge index - hash index (unique and non-unique) No selectivity estimates will be provided when running in cluster mode. * 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. * Windows service uninstalling: only remove service if it points to the currently running binary, or --force was specified. * Windows (debug only): print stacktraces on crash and run minidump * Windows (cygwin): if you run arangosh in a cygwin shell or via ssh we will detect this and use the appropriate output functions. * Windows: improve process management * fix ipv6 reverse ip lookups - so far we only did ipv4 addresses. * improve join documentation, add outer join example * run jslint for unit tests too, to prevent "memory leaks" by global js objects with native code. * fix error logging for exceptions - we wouldn't log the exception message itself so far. * improve error reporting in the http client (windows & *nix) * improve error reports in cluster * Standard Errors can now contain custom messages. -- ArangoDB Maintainer Fri, 20 Feb 2015 14:16:23 +0100 arangodb (2.5.0a4-1.1) stable; urgency=low * Changed to Version 2.5.0-alpha4 * front-end: unwanted removal of index table header after creating new index * fixed issue #1248: chrome: applications filtering not working * fixed issue #1198: queries remain in aql editor (front-end) if you navigate through different tabs * Simplify usage of Foxx Thanks to our user feedback we learned that Foxx is a powerful, yet rather complicated concept. With this release we tried to make it less complicated while keeping all its strength. That includes a rewrite of the documentation as well as some code changes as listed below: * Moved Foxx applications to a different folder. The naming convention now is: /_db///APP Before it was: /databases//: This caused some trouble as apps where cached based on name and version and updates did not apply. Hence the path on filesystem and the app's access URL had no relation to one another. Now the path on filesystem is identical to the URL (except for slashes and the appended APP) * Rewrite of Foxx routing The routing of Foxx has been exposed to major internal changes we adjusted because of user feedback. This allows us to set the development mode per mountpoint without having to change pathes and hold apps at seperate locations. * Foxx Development mode The development mode used until 2.4 is gone. It has been replaced by a much more mature version. This includes the deprecation of the javascript.dev-app-path parameter, which is useless since 2.5. Instead of having two separate app directories for production and development, apps now reside in one place, which is used for production as well as for development. Apps can still be put into development mode, changing their behavior compared to production mode. Development mode apps are still reread from disk at every request, and still they ship more debug output. * Foxx install process Installing Foxx apps has been a two step process: import them into ArangoDB and mount them at a specific mountpoint. These operations have been joined together. You can install an app at one mountpoint, that's it. No fetch, mount, unmount, purge cycle anymore. The commands have been simplified to just: * install: get your Foxx app up and running * uninstall: shut it down and erase it from disk * Foxx error output Until 2.4 the errors produced by Foxx were not optimal. Often, the error message was just `unable to parse manifest` and contained only an internal stack trace. In 2.5 we made major improvements there, including a much more finegrained error output that helps you debug your Foxx apps. The error message printed is now much closer to its source and should help you track it down. Also we added the default handlers for unhandled errors in Foxx apps: * You will get a nice internal error page whenever your Foxx app is called but was not installed due to any error * You will get a proper error message when having an uncaught error appears in any app route In production mode the messages above will NOT contain any information about your Foxx internals and are safe to be exposed to third party users. In development mode the messages above will contain the stacktrace (if available), making it easier for your in-house devs to track down errors in the application. * added `console` object to Foxx apps. All Foxx apps now have a console object implementing the familiar Console API in their global scope, which can be used to log diagnostic messages to the database. * added `org/arangodb/request` module, which provides a simple API for making HTTP requests to external services. * added optimizer rule `propagate-constant-attributes` This rule will look inside `FILTER` conditions for constant value equality comparisons, and insert the constant values in other places in `FILTER`s. For example, the rule will insert `42` instead of `i.value` in the second `FILTER` of the following query: FOR i IN c1 FOR j IN c2 FILTER i.value == 42 FILTER j.value == i.value RETURN 1 * added `filtered` value to AQL query execution statistics This value indicates how many documents were filtered by `FilterNode`s in the AQL query. Note that `IndexRangeNode`s can also filter documents by selecting only the required ranges from the index. The `filtered` value will not include the work done by `IndexRangeNode`s, but only the work performed by `FilterNode`s. * added support for sparse hash and skiplist indexes Hash and skiplist indexes can optionally be made sparse. Sparse indexes exclude documents in which at least one of the index attributes is either not set or has a value of `null`. As such documents are excluded from sparse indexes, they may contain fewer documents than their non-sparse counterparts. This enables faster indexing and can lead to reduced memory usage in case the indexed attribute does occur only in some, but not all documents of the collection. Sparse indexes will also reduce the number of collisions in non-unique hash indexes in case non-existing or optional attributes are indexed. In order to create a sparse index, an object with the attribute `sparse` can be added to the index creation commands: db.collection.ensureHashIndex(attributeName, { sparse: true }); db.collection.ensureHashIndex(attributeName1, attributeName2, { sparse: true }); db.collection.ensureUniqueConstraint(attributeName, { sparse: true }); db.collection.ensureUniqueConstraint(attributeName1, attributeName2, { sparse: true }); db.collection.ensureSkiplist(attributeName, { sparse: true }); db.collection.ensureSkiplist(attributeName1, attributeName2, { sparse: true }); db.collection.ensureUniqueSkiplist(attributeName, { sparse: true }); db.collection.ensureUniqueSkiplist(attributeName1, attributeName2, { sparse: true }); When not explicitly set, the `sparse` attribute defaults to `false` for new indexes.

A few examples are shown in [this article](http://jsteemann.github.io/blog/2015/01/28/using-custom-visitors-in-aql-graph-traversals/). * improved number of results estimated for nodes of type EnumerateListNode and SubqueryNode in AQL explain output * added AQL explain helper to explain arbitrary AQL queries The helper function prints the query execution plan and the indexes to be used in the query. It can be invoked from the ArangoShell or the web interface as follows: 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 != ...

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.

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. -- ArangoDB Maintainer Tue, 13 Jan 2015 00:53:47 +0100 arangodb (2.4.0b1-1.1) stable; urgency=low * Changed to Version 2.4.0-beta1 * 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 * 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.

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 * 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. However, the default configuration files shipped with ArangoDB have been changed. The number of server threads has been increased in the configuration files, and the number of V8 contexts is now explicitly set in the configuration files (to the same value as the number of server threads was set to in 2.2). If you are using the default config files or merge them with your local config files, please review if the higher 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. * 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("

some HTML

"); 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 -- ArangoDB Maintainer Sat, 08 Nov 2014 00:09:03 +0100 arangodb (2.3.0b1-1.1) stable; urgency=low * Changed to Version 2.3.0-beta1 * added command-line option `--javascript.v8-contexts` to control the number of V8 contexts created in arangod.

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.

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 -- ArangoDB Maintainer Fri, 08 Aug 2014 12:26:37 +0200 arangodb (2.2.2r1-1.1) stable; urgency=low * Changed to Version 2.2.2-rc1 * 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 -- ArangoDB Maintainer Wed, 06 Aug 2014 11:21:54 +0200 arangodb (2.2.1-1.1) stable; urgency=low * Changed to Version 2.2.1 * fixed issue with --check-version: when creating a new database the check failed * issue #947 Foxx applicationContext missing some properties * added startup option `--wal.suppress-shape-information` Setting this option to `true` will reduce memory and disk space usage and require less CPU time when modifying documents or edges. It should therefore be turned on for standalone ArangoDB servers. However, for servers that are used as replication masters, setting this option to `true` will effectively disable the usage of the write-ahead log for replication, so it should be set to `false` for any replication master servers.

Data changes are logged into the write-ahead log in ArangoDB 2.2, and not separately by the replication logger. The replication logger object is still there in ArangoDB 2.2 to ensure backwards-compatibility, however, logging cannot be started, stopped or configured anymore. Using any of these methods will do nothing. This also affects the following HTTP API methods: - `PUT /_api/replication/logger-start` - `PUT /_api/replication/logger-stop` - `GET /_api/replication/logger-config` - `PUT /_api/replication/logger-config` Using any of these methods is discouraged from now on as they will be removed in future versions of ArangoDB. * INCOMPATIBLE CHANGE: replication of transactions has changed. Previously, transactions were logged on a master in one big block and shipped to a slave in one block, too. Now transactions will be logged and replicated as separate entries, allowing transactions to be bigger and also ensure replication progress. This change also affects the behavior of the `stop` method of the replication applier. If the replication applier is now stopped manually using the `stop` method and later restarted using the `start` method, any transactions that were unfinished at the point of stopping will be aborted on a slave, even if they later commit on the master. In ArangoDB 2.2, stopping the replication applier manually should be avoided unless the goal is to stop replication permanently or to do a full resync with the master anyway. If the replication applier still must be stopped, it should be made sure that the slave has fetched and applied all pending operations from a master, and that no extra transactions are started on the master before the `stop` command on the slave is executed. Replication of transactions in ArangoDB 2.2 might also lock the involved collections on the slave while a transaction is either committed or aborted on the master and the change has been replicated to the slave. This change in behavior may be important for slave servers that are used for read-scaling. In order to avoid long lasting collection locks on the slave, transactions should be kept small. The `_replication` system collection is not used anymore in ArangoDB 2.2 and its usage is discouraged. * INCOMPATIBLE CHANGE: the figures reported by the `collection.figures` method now only reflect documents and data contained in the journals and datafiles of collections. Documents or deletions contained only in the write-ahead log will not influence collection figures until the write-ahead log garbage collection kicks in. The figures for a collection might therefore underreport the total resource usage of a collection. Additionally, the attributes `lastTick` and `uncollectedLogfileEntries` have been added to the result of the `figures` operation and the HTTP API method `PUT /_api/collection/figures` * added `insert` method as an alias for `save`. Documents can now be inserted into a collection using either method: db.test.save({ foo: "bar" }); db.test.insert({ foo: "bar" }); * added support for data-modification AQL queries * added AQL keywords `INSERT`, `UPDATE`, `REPLACE` and `REMOVE` (and `WITH`) to support data-modification AQL queries. Unquoted usage of these keywords for attribute names in AQL queries will likely fail in ArangoDB 2.2. If any such attribute name needs to be used in a query, it should be enclosed in backticks to indicate the usage of a literal attribute name. For example, the following query will fail in ArangoDB 2.2 with a parse error: FOR i IN foo RETURN i.remove and needs to be rewritten like this: FOR i IN foo RETURN i.`remove` * disallow storing of JavaScript objects that contain JavaScript native objects of type `Date`, `Function`, `RegExp` or `External`, e.g. db.test.save({ foo: /bar/ }); db.test.save({ foo: new Date() }); will now print Error: cannot be converted into JSON shape: could not shape document Previously, objects of these types were silently converted into an empty object (i.e. `{ }`).

The write-ahead log is a set of append-only logfiles, and it is used in case of a crash recovery and for replication. Data from the write-ahead log will eventually be moved into the journals or datafiles of collections, allowing the server to remove older write-ahead log logfiles. Figures of collections will be updated when data are moved from the write-ahead log into the journals or datafiles of collections. Cross-collection transactions in ArangoDB should benefit considerably by this change, as less writes than in previous versions are required to ensure the data of multiple collections are atomcially and durably committed. All data-modifying operations inside transactions (insert, update, remove) will write their operations into the write-ahead log directly, making transactions with multiple operations also require less physical memory than in previous versions of ArangoDB, that required all transaction data to fit into RAM. The `_trx` system collection is not used anymore in ArangoDB 2.2 and its usage is discouraged. The data in the write-ahead log can also be used in the replication context. The `_replication` collection that was used in previous versions of ArangoDB to store all changes on the server is not used anymore in ArangoDB 2.2. Instead, slaves can read from a master's write-ahead log to get informed about most recent changes. This removes the need to store data-modifying operations in both the actual place and the `_replication` collection. * removed startup option `--server.disable-replication-logger` This option is superfluous in ArangoDB 2.2. There is no dedicated replication logger in ArangoDB 2.2. There is now always the write-ahead log, and it is also used as the server's replication log. Specifying the startup option `--server.disable-replication-logger` will do nothing in ArangoDB 2.2, but the option should not be used anymore as it might be removed in a future version. * changed behavior of replication logger There is no dedicated replication logger in ArangoDB 2.2 as there is the write-ahead log now. The existing APIs for starting and stopping the replication logger still exist in ArangoDB 2.2 for downwards-compatibility, but calling the start or stop operations are no-ops in ArangoDB 2.2. When querying the replication logger status via the API, the server will always report that the replication logger is running. Configuring the replication logger is a no-op in ArangoDB 2.2, too. Changing the replication logger configuration has no effect. Instead, the write-ahead log configuration can be changed. * removed MRuby integration for arangod ArangoDB had an experimental MRuby integration in some of the publish builds. This wasn't continuously developed, and so it has been removed in ArangoDB 2.2. This change has led to the following startup options being superfluous: - `--ruby.gc-interval` - `--ruby.action-directory` - `--ruby.modules-path` - `--ruby.startup-directory` Specifying these startup options will do nothing in ArangoDB 2.2, but the options should be avoided from now on as they might be removed in future versions. * reclaim index memory when last document in collection is deleted Previously, deleting documents from a collection did not lead to index sizes being reduced. Instead, the already allocated index memory was re-used when a collection was refilled. Now, index memory for primary indexes and hash indexes is reclaimed instantly when the last document from a collection is removed. * inlined and optimized functions in hash indexes * added AQL TRANSLATE function This function can be used to perform lookups from static lists, e.g. LET countryNames = { US: "United States", UK: "United Kingdom", FR: "France" } RETURN TRANSLATE("FR", countryNames) * fixed datafile debugger * fixed check-version for empty directory * moved try/catch block to the top of routing chain * added mountedApp function for foxx-manager * fixed issue #883: arango 2.1 - when starting multi-machine cluster, UI web does not change to cluster overview * fixed dfdb: should not start any other V8 threads * cleanup of version-check, added module org/arangodb/database-version, added --check-version option * fixed issue #881: [2.1.0] Bombarded (every 10 sec or so) with "WARNING format string is corrupt" when in non-system DB Dashboard * specialized primary index implementation to allow faster hash table rebuilding and reduce lookups in datafiles for the actual value of `_key`. * issue #862: added `--overwrite` option to arangoimp * removed number of property lookups for documents during AQL queries that access documents * prevent buffering of long print results in arangosh's and arangod's print command this change will emit buffered intermediate print results and discard the output buffer to quickly deliver print results to the user, and to prevent constructing very large buffers for large results * removed sorting of attribute names for use in a collection's shaper sorting attribute names was done on document insert to keep attributes of a collection in sorted order for faster comparisons.

Changing the replication logger configuration has no effect. Instead, the write-ahead log configuration can be changed. * removed MRuby integration for arangod ArangoDB had an experimental MRuby integration in some of the publish builds. This wasn't continuously developed, and so it has been removed in ArangoDB 2.2. This change has led to the following startup options being superfluous: - `--ruby.gc-interval` - `--ruby.action-directory` - `--ruby.modules-path` - `--ruby.startup-directory` Specifying these startup options will do nothing in ArangoDB 2.2, but the options should be avoided from now on as they might be removed in future versions. * reclaim index memory when last document in collection is deleted Previously, deleting documents from a collection did not lead to index sizes being reduced.

Data from the write-ahead log will eventually be moved into the datafiles of collections, allowing the server to remove older write-ahead log logfiles. Cross-collection transactions in ArangoDB should benefit considerably by this change, as less writes than in previous versions is required to ensure the data of multiple collections are atomcially and durably committed. All data-modifying operations inside transactions (insert, update, remove) will write their operations into the write-ahead log directly, making transactions with multiple operations also require less physical memory than in previous versions of ArangoDB, where most parts of transactions were handled in RAM first.

The current user is the username that was specified in the `Authorization` HTTP header of the request. If authentication is turned off or the query was executed outside a request context, the function will return `null`. * fixed issue #796: Searching with newline chars broken? fixed slightly different handling of backslash escape characters in a few AQL functions. Now handling of escape sequences should be consistent, and searching for newline characters should work the same everywhere * added OpenSSL version check for configure It will report all OpenSSL versions < 1.0.1g as being too old. `configure` will only complain about an outdated OpenSSL version but not stop. * require C++ compiler support (requires g++ 4.8, clang++ 3.4 or Visual Studio 13) * less string copying returning JSONified documents from ArangoDB, e.g. via HTTP GET `/_api/document//` * issue #798: Lower case http headers from arango This change allows returning capitalized HTTP headers, e.g. `Content-Length` instead of `content-length`. The HTTP spec says that headers are case-insensitive, but in fact several clients rely on a specific case in response headers. This change will capitalize HTTP headers if the `X-Arango-Version` request header is sent by the client and contains a value of at least `20100` (for version 2.1). The default value for the compatibility can also be set at server start, using the `--server.default-api-compatibility` option. * simplified usage of `db._createStatement()` Previously, the function could not be called with a query string parameter as follows: db._createStatement(queryString); Calling it as above resulted in an error because the function expected an object as its parameter. From now on, it's possible to call the function with just the query string. * make ArangoDB not send back a `WWW-Authenticate` header to a client in case the client sends the `X-Omit-WWW-Authenticate` HTTP header. This is done to prevent browsers from showing their built-in HTTP authentication dialog for AJAX requests that require authentication. ArangoDB will still return an HTTP 401 (Unauthorized) if the request doesn't contain valid credentials, but it will omit the `WWW-Authenticate` header, allowing clients to bypass the browser's authentication dialog. * added REST API method HTTP GET `/_api/job/job-id` to query the status of an async job without potentially fetching it from the list of done jobs * fixed non-intuitive behaviour in jobs API: previously, querying the status of an async job via the API HTTP PUT `/_api/job/job-id` removed a currently executing async job from the list of queryable jobs on the server. Now, when querying the result of an async job that is still executing, the job is kept in the list of queryable jobs so its result can be fetched by a subsequent request. * use a new data structure for the edge index of an edge collection. This improves the performance for the creation of the edge index and in particular speeds up removal of edges in graphs. Note however that this change might change the order in which edges starting at or ending in a vertex are returned. However, this order was never guaranteed anyway and it is not sensible to guarantee any particular order. * provide a size hint to edge and hash indexes when initially filling them this will lead to less re-allocations when populating these indexes this may speed up building indexes when opening an existing collection * don't requeue identical context methods in V8 threads in case a method is already registered * removed arangod command line option `--database.remove-on-compacted` * export the sort attribute for graph traversals to the HTTP interface * add support for arangodump/arangorestore for clusters -- ArangoDB Maintainer Mon, 12 May 2014 19:29:58 +0200 arangodb (2.1.0a9-1.1) stable; urgency=low * Changed to Version 2.1.0-alpha9 * added server-side periodic task management functions: - require("org/arangodb/tasks").register(): registers a periodic task - require("org/arangodb/tasks").unregister(): unregisters and removes a periodic task - require("org/arangodb/tasks").get(): retrieves a specific tasks or all existing tasks the previous undocumented function `internal.definePeriodic` is now deprecated and will be removed in a future release. * decrease the size of some seldomly used system collections on creation.

Now handling of escape sequences should be consistent, and searching for newline characters should work the same everywhere * added OpenSSL version check for configure It will report all OpenSSL versions < 1.0.1g as being too old. `configure` will only complain about an outdated OpenSSL version but not stop. * require C++ compiler support (requires g++ 4.8, clang++ 3.4 or Visual Studio 13) * less string copying returning JSONified documents from ArangoDB, e.g. via HTTP GET `/_api/document//` * issue #798: Lower case http headers from arango This change allows returning capitalized HTTP headers, e.g. `Content-Length` instead of `content-length`. The HTTP spec says that headers are case-insensitive, but in fact several clients rely on a specific case in response headers. This change will capitalize HTTP headers if the `X-Arango-Version` request header is sent by the client and contains a value of at least `20100` (for version 2.1). The default value for the compatibility can also be set at server start, using the `--server.default-api-compatibility` option. * simplified usage of `db._createStatement()` Previously, the function could not be called with a query string parameter as follows: db._createStatement(queryString); Calling it as above resulted in an error because the function expected an object as its parameter. From now on, it's possible to call the function with just the query string. * make ArangoDB not send back a `WWW-Authenticate` header to a client in case the client sends the `X-Omit-WWW-Authenticate` HTTP header. This is done to prevent browsers from showing their built-in HTTP authentication dialog for AJAX requests that require authentication. ArangoDB will still return an HTTP 401 (Unauthorized) if the request doesn't contain valid credentials, but it will omit the `WWW-Authenticate` header, allowing clients to bypass the browser's authentication dialog. * added REST API method HTTP GET `/_api/job/job-id` to query the status of an async job without potentially fetching it from the list of done jobs * fixed non-intuitive behaviour in jobs API: previously, querying the status of an async job via the API HTTP PUT `/_api/job/job-id` removed a currently executing async job from the list of queryable jobs on the server. Now, when querying the result of an async job that is still executing, the job is kept in the list of queryable jobs so its result can be fetched by a subsequent request. * use a new data structure for the edge index of an edge collection.

For example, the following queries will be affected by change: FOR doc IN docs FILTER doc.value < { foo: "bar" } RETURN doc FOR doc IN docs FILTER doc.value >= [ 1, 2, 3 ] RETURN doc The following queries will not be affected by the change: FOR doc IN docs FILTER doc.value == 1 RETURN doc FOR doc IN docs FILTER doc.value == "foo" RETURN doc FOR doc IN docs FILTER doc.value == [ 1, 2, 3 ] RETURN doc FOR doc IN docs FILTER doc.value == { foo: "bar" } RETURN doc * INCOMPATIBLE CHANGE: removed undocumented method `collection.saveOrReplace` this feature was never advertised nor documented nor tested. * INCOMPATIBLE CHANGE: removed undocumented REST API method `/_api/simple/BY-EXAMPLE-HASH` this feature was never advertised nor documented nor tested. * added explicit startup parameter `--server.reuse-address` This flag can be used to control whether sockets should be acquired with the SO_REUSEADDR flag. Regardless of this setting, sockets on Windows are always acquired using the SO_EXCLUSIVEADDRUSE flag. * removed undocumented REST API method GET `/_admin/database-name` * added user validation API at POST `/_api/user/` * slightly improved users management API in `/_api/user`: Previously, when creating a new user via HTTP POST, the username needed to be passed in an attribute `username`. When users were returned via this API, the usernames were returned in an attribute named `user`. This was slightly confusing and was changed in 1.5 as follows: - when adding a user via HTTP POST, the username can be specified in an attribute `user`. If this attribute is not used, the API will look into the attribute `username` as before and use that value. - when users are returned via HTTP GET, the usernames are still returned in an attribute `user`. This change should be fully downwards-compatible with the previous version of the API. * added AQL SLICE function to extract slices from lists * removed check-server binary * made module loader more node compatible * the startup option `--javascript.package-path` for arangosh is now deprecated and does nothing.
