Change Log

All notable changes to the "PostgreSQL Hacker Helper" extension will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[1.4.5]

No changes

[1.4.4]

Add typedefs.list file preprocessing for feeding to pg_bsd_indent. Processed file saved in /tmp/pg-hacker-helper.typedefs.list file and may be reused between different sessions. Without processing raw file (downloaded from buildfarm) pg_bsd_indent produces invalid formatted code.

[1.4.3]

Add pre and post steps around running pg_bsd_indent to handle some formatting cases, like single space between type name and *. Relates to bug #3.

[1.4.2]

Fixed

Fix pg_bsd_indent Path setting not handled due to code constants misuse. Relates to bug #2.

[1.4.1]

Added

Add extension files bootstrapping: Makefile, *.c, *.sql, *.control, tests. To create extension this way need to run command Bootstrap extension from command palette.

Support for fixed size array expansion. Type of field must be in form type[size].

Fixed

Fix invalid struct detection in variables view: top level structs are not expandable.

Fix variable length arrays fields displayed as expandable. I.e. for List last field previously was displayed as expandable, but there are no elements shown.

[1.4.0]

Added

  • Support for custom PostgreSQL source code directories. It can be set using postgresql-hacker-helper.srcPath in settings. This setting is used to start searching for required files (i.e. default node tag files or pg_bsd_indent). NOTE: if custom NodeTag files are set with relative path - search start from workspace directory, not your custom srcPath.

Fixed

  • Invalid message formatting for VS Code greater than 1.74.0. Caused by incompatible (with extension's) formatting logic used.

[1.3.0]

Added

  • Formatting using pg_bsd_indent with Format Document VS Code functionality. Supported for PostgreSQL starting from 10 version.

  • Show elements to which Bitmapset and Relids points: Relids (RangeTblEntry and RelOptInfo) or index in array (show element of that array)

Changed

  • Integration with VS Code logging (output channel). Now can specify log level in Output window.

[1.2.1]

Changed

  • aliases parameter in configuration file now works for every type, not only Node types.

Fixed

  • Check breakpoint in bms_first_member function to avoid infinite loop when evaluating bms elements.
  • Add support for MemoryContext Node

[1.2.0]

Added

  • Compatibility with PostgreSQL starting from 8.0 version. This includes:

    • Linked List implementation of List
    • Bitmapset traversal using bms_first_member and temp object
    • Bitmapset handling for versions up to 16, when it was not Node type

  • Compatibility with VS Code versions starting from 1.30. But some features can be unaccessible due to API incompatibility.

    In example some versions do not have Dump Node to stdout in variables debug context menu.

  • Add more NodeTags - searched from version 8.0 to 17. Current amount - 558.

Fixed

  • Log level not updated until restart of extension (or VS Code).

  • Invalid Node casting when declared type has struct qualifier and NodeTag type do not have it.

    Example: typedef JoinPath NestJoin (for versions up to 14) - failed to show members when declared type is struct Path *.

[1.1.2]

Fixed

  • Invalid cast to List - show members of declared type, not based on tag. I.e. when Node * is declared type, but T_List real tag value - shown members were for Node (single type member).

Added

  • 137 new array special members. Total amount - 170.

  • Support for Plan structs for observing Node variables.

Changed

  • Optimize extension startup path: remove function dependencies, no depending on NodeTag files

  • NodeTags stored as constant array in extension. Reading from file is not necessary for operating.

[1.1.1]

Fixed

  • Fix Bitmapset elements not shown for postgres version below 17. Used function bms_is_valid_set was introduced in 17 version.

[1.1.0]

Added

  • Support for Bitmapset and Relids - show elements of set and it's length in $elements$ and $length$ pseudo-members.

  • User defined type alises for Node types. Roughly speaking, it specifies typedefs for types and when test for Node variable fails extension tries to substitute typename with given alias. This was introduced because of typedef Bitmapset *Relids - there is no T_Relids NodeTag.

Changed

  • Extension is activating automatically on presence of files:

    • pgsql_hacker_helper.json - extension's config file
    • src/include/node/nodes.h, src/include/node/nodetags.h - files with NodeTag values (vs code settings not checked)

  • Update config file schema to 2 version - default version. nodeTag member replaced with typeName: old behaviour was designed to support only Node variables, but now it allows any type to specify custom arrays. Also, in nodeTag leading T_ prefix was removed, new member does not do it.

  • Postgres variables view in debug container shows only when extension is activated and in debug mode.

[1.0.0]

Added

  • T_XidList to supported List subtype

Removed

  • EPQState from list of array special members - it does not have NodeTag

[0.2.0]

Added

  • More array special members. Totally - 36 special members.
  • Separate json configuration file where you can add custom special members. This file can be created manually or using command (in command palette) PgSQL: Open or create configuration file (JSON)
  • Command and button to refresh Pg variables view: command palette and refresh button on top of Pg variables view. Note: normally, you don't need to run this, but when some errors happen and variables are not refreshed you can perform this action.
  • Setting to specify log level. Default: INFO Available levels:
    • DEBUG
    • INFO
    • WARNING
    • ERROR
    • DISABLE
  • Setting to specify list of NodeTag files. Default:
    • src/include/nodes/nodes.h
    • src/include/nodes/nodetags.h

Changed

  • Real NodeTag shows up in variable name (in square brackets) if it differs from declared. This can happen when type of variable Path *, but real path is ProjectionPath, so it show Path * [ProjectionPath]

[0.1.1]

Fix

  • Only valid pointer variables are expanded in Pg variables view

[0.1.0]

Added

  • Separate view with Node * variables expanded
  • Dumping Node * to stdout using pprint function
