2.0.0-alpha.6 - 2022-05-05

Breaking changes

• Previously, specifying an empty projection array for Model database methods (e.g. find, findById) would behave the same as specifying no projection at all. This change adjusts that behavior so that specifying an empty projection array will instead return no data. (#86)

Fixed

• Corrected an issue with saving subdocument arrays defined with multipart paths where the resulting saved data would be formatted incorrectly in the database (#85)
• Added missing @babel/runtime dependency (#105)
• If a database value cannot be transformed, log the original value and not the value after a transformation attempt (#106)

2.0.0-alpha.5 - 2022-04-19

Added

• Allow user defined properties in Model methods. These will be stored in the S$MVOM named common area. (#76)
• Validate database server query limits prior to execution of query (#79)

2.0.0-alpha.4 - 2022-04-12

Breaking changes

• Change database I/O for records to use delimited strings instead of arrays (#60)
  • A new non-enumerable _originalRecordString property now exists on the Model instance
  • Model instances can no longer be constructed from arrays. Delimited strings can be used instead.
  • The Document constructor is now protected and should not be instantiated directly. Use of the static createDocumentFromRecordString should be used instead.

Added

• Allow http/s agent to be passed to Connection (#45)
• Allow type information to be specified for dictionaries that are not part of the data definitions (#53)

2.0.0-alpha.3 - 2022-03-22

Fixed

• Fixed an issue where the time transformations were returning the incorrect value on the date a daylight saving time transition occurred (#42)
• Fixed an issue where property descriptors were being added unnecessarily to properties on the Document class which had been migrated to JS private syntax (#41)
• Fixed an issue where the default dbFormat of 'ms' for ISOCalendarDateTime schema types was not properly passing the defaulted format to the ISOTime constructor. This led to incorrect transformations of the time component of the ISOCalendarDateTime. (#50)

Changed

• moment was replaced with date-fns for use in date and time conversions since moment is in maintenance mode. (#42)
• Logging behaviors were changed to have a different severity level for many log events. Additionally, all logs now include the account name in the emitted log message. (#44)

Added

• When an MVIS connection times out, a new TimeoutError will be emitted instead of MvisError. Additionally, a new UnknownError could possibly be emitted if the caught error is not of type AxiosError (from axios library). (#43)

2.0.0-alpha.2 - 2022-03-17

Fixed

• The findById and findByIds database features were returning empty string when a record was not found. However, the types for the responses were anticipating null to be returned in this scenario. The handling code was anticipating null and was returning an empty Model instance instead of returning null as expected. Use of null is a better pattern and the database code was adjusted to return null instead of empty string. (#37)
• The unibasic path for db server feature deployments was resolving to the incorrect file system location (#37)
• The Document and Model constructors were incorrectly only allowing an option of either record or data to be supplied. It is valid syntax to supply both so the restrictions on the constructor options were relaxed. (#37)

2.0.0-alpha.1 - 2022-03-14

Breaking Changes

• The encrypt and decrypt functions are no longer overloaded to accept or return arrays and no longer accept or return null. All handling of arrays and null values has been internalized. (#29)

Fixed

• The _id property of Model instances was inadvertently not enumerable. This fix ensures that the _id property will be enumerable. (#31)

2.0.0-alpha.0 - 2022-03-11

Breaking Changes

• Minimum Node version is now 14.19.0
• The Schema constructor definitions no longer accept constructors for the type property in schema property definitions. Instead, the type will be string literals indicating the property's type (e.g. 'string').
• Several exported types have been improved or renamed
• There is no longer a default export from the library. The main export now includes named exports Connection, Document, Schema, and the various Error classes.
• createConnection has been changed from a standalone exported function to a static method on the Connection class. This is now the only supported mechanism for instiantiating a Connection.
• ConnectionManagerError has been renamed as MvisError and its properties similarly renamed since the official Rocket product is "MVIS"

Changed

• Migrated library from BitBucket to GitHub
• Update repository URL in package.json (#3)
• Update all dependencies to latest version
• Library has been completely converted to TypeScript (#14, #18, #20, #22, and #23)
• Uses STORIS published eslint, prettier, and typescript configurations
• Convert changelog to the Keep-a-Changelog standard

Added

• Use GitHub actions for CI (#1)
• Use Renovate to keep dependencies up to date (#2)

1.0.0 - 2022-02-22

No changes; only publish 1.0.0 stable release

1.0.0-rc.1 - 2021-10-19

Fixed

• Fix projection error on schemaless models

1.0.0-rc.0 - 2021-10-18

Breaking changes

• Node 12 is now minimum version

Added

• Allow explicit $and operator for queries
• Improve Query unit tests
• Allow schematically defined foreign key validations
• Allow projection operators to be passed to queries to limit returned data from data server and transformations
• Allow reading binary files as Base64 encoded

Changed

• Update dependencies to remove security warnings

0.9.4 - 2021-06-30

Changed

• Update all dependencies
• Format the ISOCalendarDateTime type to have the time component left padded with zeroes

0.9.3 - 2021-05-07

Changed

• Update production dependencies to remedy high vulnerability security issues

0.9.2 - 2020-11-19

Fixed

• Several properties on the Document instance were intended to not be enumerable and were not getting configured properly to ensure that. This change ensures that the transformDocumentToRecord, _transformRecordToDocument, and validate properties are not configurable, not enumerable, and not writable. Since Model inherits from Document, this will affect instances of that class as well.

0.9.1 - 2020-05-22

Fixed

• When a document's property is a schema type of Array or NestedArray, required validation will fail when the property is not defined. This is because during validation the undefined property gets cast to null and then the array gets cast to [null] during validation which fails. The issue is that undefined and null values are not cast to arrays prior to validation in the same way that DocumentArrays are. This change casts null and undefined properties to [] and scalars to an array of that scalar during property validation.

0.9.0 - 2020-05-18

Breaking changes

• Eliminate implicit required validation of primitive arrays that was occurring if the primitive's schema definition indicated it was required. This effectively made it so that arrays must have a length greater than 0 if the contents of the array were required. This caused the required flag to effectively serve double-duty -- preventing null/undefined contents of arrays and enforcing that arrays contained contents.

0.8.0 - 2020-04-21

Added

• Add support to encrypt and decrypt strings and ISO calendar dates. String and ISOCalendarDate type fields can be marked as encrypted. The Schema constructor now accepts optional encrypt and decrypt functions. If a field is marked as encrypted these provided functions will be run.

0.7.0 - 2020-04-03

Changed

• Update to fix dependency vulnerabilities
• Expose the Document constructor and allow a record to be passed in the constructor without having fetched it from the DB

0.6.2 - 2020-03-24

Fixed

• Fix a deployment issue introduced in 0.6.0. Make sure that all features needed for the deploy feature are deployed as part of a bootstrap step
• Add temporary workarounds for several issues identified in UniQuery
  • Using the returning clause on a query where a query limit is exceeded causes an abort (proposed to be fixed in UniData 8.2.2)
  • Exceeding the sentence length limit does to set an error condition in @system.return.code therefore returning incorrect results instead of an error.

0.6.1 - 2020-03-13

Added

• Allow for regular expression pattern matching for strings and ids. Strings will accept a property named match in the schema definition for any string type. Document ids can be matched by providing an idMatch property to the Schema constructor options.

Changed

• Update some vulnerable dependencies

0.6.0 - 2020-03-03

Breaking changes

• Add new setup and teardown features which will run before and after a subroutine feature to setup and teardown the environment. While configurable, the initial implementation creates and clears a named common block called S$MVOM, which includes one variable called S$MVOM.PROCESS set to true. UniBasic programs can check for this variable to determine if they were initiated by MVIS. This may be necessary when code not shipped through MVOM is run like in a database trigger or virtual dictionary.

UniBasic programs should include the below to use this new variable:

COM /S$MVOM/ S$MVOM.PROCESS

• Enhance the save action to support clearing all attributes before writing out the record. This fixes an issue with schemaless documents where the record being written has less attributes than what is already on disk. This is automatically set when working with schemaless files.

0.5.2 - 2020-02-25

Added

• Allow for null schemas passed to the model constructor. When schemas are null, no mapping of the record to a document (and vice versa) will occur. Instead, a property named _raw will be added to the document which contains an array of the record contents. When saving, this array will overwrite the entire record.

0.5.1 - 2019-11-21

Changed

• Rollback fs-extra version to avoid memory leak

0.5.0 - 2019-11-11

Breaking changes

• Fix simple and document array handling so they can be cleared using an empty array syntax and also update correctly when changing the length
• Change exported error names so they contain an Error suffix for clarity

Changed

• Update dependencies and begin conversion to TypeScript

0.4.0 - 2019-07-18

Breaking changes

• String types with an enumeration of empty string will return empty string instead of null from the database

Changed

• Improve the Model class in the typescript declaration

0.3.5 - 2019-06-03

Fixed

• Correct static members on Model class in TS declaration file

0.3.4 - 2019-05-30

Added

• Add TypeScript declaration file

0.3.3 - 2019-05-16

Fixed

• Ensure that the count property returned from findAndCount is numeric

0.3.2 - 2019-05-13

Added

• Add new findByIds static model method which finds a list of documents by id.
• Add new findAndCount static model method which returns both the documents matching the query as well as the count of all documents matching the query irrespective of skip and limit

0.3.1 - 2018-12-21

Fixed

• Fix an issue where enum validation returns a data validation error on null values on non-required fields

0.3.0 - 2018-12-17

Breaking changes

• Correctly format an attribute that only contains subvalued data. Previously this returned a string with embedded subvalue delimiters. This now returns a nested array.

Changed

• Improve the performance of the server-side formatDocument routine on large records by switching to REMOVE and udoAppendArrayItem
• Fix an abort from the U2 digest function when reading or overwriting a previously empty record

0.2.1 - 2018-10-22

Added

• The constant values for queries will now be converted from the external schema format to the internal u2 format. This affects the date/time types as well as Booleans.
• Add support for specifying allowed enum values in the schema for string types

0.2.0 - 2018-09-18

Breaking changes

• Connections now accept a timeout parameter which will override the default of no timeout. The default remains to be no timeout.
• The request and response properties of the ConnectionManager error object have now been renamed so they do not appear to be errors that directly came from axios. They are now connectionManagerRequest and connectionManagerResponse respectively.
• The Connection class is no longer exported. Connections should be established via the createConnection method which now accepts all parameters that the Connection class accepts
• mvom will no longer create a default winston logger if one is not passed to the connection constructor. All consumers who wish to have mvom provide logging should pass in their own logger (such as winston) which provides methods conforming to the npm log levels.

Changed

• Nearly all dependencies and devDependencies have been updated to the latest versions
• Db server tier errors can now be cast to error class instances. Errors due to record locking will now be cast to RecordLockedError and errors due to record version mismatches will be cast to RecordVersionError
• Db server errors occurring during save will now enrich the error object with the filename and record id in the error object's other property
• All errors thrown from mvom will now contain a source property with a value of mvom

0.1.0 - 2018-08-10

Breaking changes

We've graduated from Alpha to Beta! Semver has been updated so breaking vs. non-breaking changes can be more easily identified go forward.

Fixed

• A bug was discovered where a subdocument array could not reference a multi-part path. That is, the subdocument array had a path in the format of x.y indicating the data was located at a particular attribute and value and the array should iterate across the subvalue. In this structure, the properties in the subdocument arrays would end up empty. This has been corrected.

0.0.10 - 2018-06-12

Changed

• An object in the Schema is now only considered to be a "data definition" if it contains both a type and a path property. If an object doesn't contain both of these properties, it will be treated as a subdocument object instead of a data definition. The upshot of this is that type can now be used as a data-describing property in a Schema definition, provided that it does not appear alongside a path property in that same definition.

0.0.9 - 2018-06-07

Added

• Connection instances now expose getDbDate, getDbDateTime, and getDbTime functions. These can be used to calculate the date and time values as represented at the database layer since it is likely to differ from the layer running mvom. This will allow consumers to get these values so they can be provided in the data. Note: This information is cached with a tunable time period (default 1 hour) in order to provide low latency feedback but also reasonably handle shifts in the database time (e.g. daylight saving time, server migrations, etc.)

0.0.8 - 2018-05-30

Breaking changes

• Document constructor no longer accepts "record" -- instead it accepts an object of data
• Plain objects can now be used with subdocuments, enabling far easier use of these structures

0.0.7 - 2018-05-07

Breaking changes

• Use array of arrays for sort criteria to preserve sequencing; can no longer be specified as object

0.0.6 - 2018-04-19

Added

• Provide default dictionary of @ID for _id property

0.0.5 - 2018-04-17

Breaking changes

• Do not treat missing records as an error condition - instead return null from findById

0.0.4 - 2018-04-16

Breaking changes

• Partially revert changes to default export -- continue to export as named exports as well

0.0.3 - 2018-04-16

Added

• When a query property is equal to an array, automatically convert to $in query
• Change default export from library to include Connection, Errors, and Schema

0.0.2 - 2018-04-09

Added

• Connection is now exported from main module
• __v is now an accessible property in model instances
• Connection instances now have a status

Fixed

• Models cannot be created from connection instances that have not been opened

0.0.1 - 2018-03-19

Initial alpha release of this library! Thanks for using it!
