* Move jsonapi.c and jsonapi.h to src/common.Robert Haas2020-01-29
| | | | | | | | | | | To make this work, (1) makeJsonLexContextCstringLen now takes the encoding to be used as an argument; (2) check_stack_depth() is made to do nothing in frontend code, and (3) elog(ERROR, ...) is changed to pg_log_fatal + exit in frontend code. Mark Dilger, reviewed and slightly revised by me. Discussion: http://postgr.es/m/CA+TgmoYfOXhd27MUDGioVh6QtpD0C1K-f6ObSA10AWiHBAL5bA@mail.gmail.com
* Move some code from jsonapi.c to jsonfuncs.c.Robert Haas2020-01-27
| | | | | | | | | | | | | | Specifically, move those functions that depend on ereport() from jsonapi.c to jsonfuncs.c, in preparation for allowing jsonapi.c to be used from frontend code. A few cases where elog(ERROR, ...) is used for can't-happen conditions are left alone; we can handle those in some other way in frontend code. Reviewed by Mark Dilger and Andrew Dunstan.

* Adjust pg_parse_json() so that it does not directly ereport().Robert Haas2020-01-27
| | | | | | | | | | | | | | | | | | | | | Instead, it now returns a value indicating either success or the type of error which occurred. The old behavior is still available by calling pg_parse_json_or_ereport(). If the new interface is used, an error can be thrown by passing the return value of pg_parse_json() to json_ereport_error(). pg_parse_json() can still elog() in can't-happen cases, but it seems like that issue is best handled separately. Adjust json_lex() and json_count_array_elements() to return an error code, too. This is all in preparation for making the backend's json parser available to frontend code. Reviewed and/or tested by Mark Dilger and Andrew Dunstan. Discussion: http://postgr.es/m/CA+TgmoYfOXhd27MUDGioVh6QtpD0C1K-f6ObSA10AWiHBAL5bA@mail.gmail.com
* Split JSON lexer/parser from 'json' data type support.Robert Haas2020-01-24
| | | | | | | | | | | | | | | | | | | | Keep the code that pertains to the 'json' data type in json.c, but move the lexing and parsing code to a new file jsonapi.c, a name I chose because the corresponding prototypes are in jsonapi.h. This seems like a logical division, because the JSON lexer and parser are also used by the 'jsonb' data type, but the SQL-callable functions in json.c are a separate thing. Also, the new jsonapi.c file needs to include far fewer header files than json.c, which seems like a good sign that this is an appropriate place to insert an abstraction boundary. I took the opportunity to remove a few apparently-unneeded includes from json.c at the same time. Patch by me, reviewed by David Steele, Mark Dilger, and Andrew Dunstan. The previous commit was, too, but I forgot to note it in the commit message. Discussion: http://postgr.es/m/CA+TgmoYfOXhd27MUDGioVh6QtpD0C1K-f6ObSA10AWiHBAL5bA@mail.gmail.com
* Adjust src/include/utils/jsonapi.h so it's not backend-only.Robert Haas2020-01-24
| | | | | | | | | | | | | | | The major change here is that we no longer include jsonb.h into jsonapi.h. The reason that was necessary is that jsonapi.h included several prototypes functions in jsonfuncs.c that depend on the Jsonb type. Move those prototypes to a new header, jsonfuncs.h, and include it where needed. The other change is that JsonEncodeDateTime is now declared in json.h rather than jsonapi.h. Taken together, these steps eliminate all dependencies of jsonapi.h on backend-only data types and header files, so that it can potentially be included in frontend code.

* Allow datetime values in JsonbValueAlexander Korotkov2019-09-25
| | | | | | | | | | | | | | | | | | | | SQL/JSON standard allows manipulation with datetime values. So, it appears to be convinient to allow datetime values to be represented in JsonbValue struct. These datetime values are allowed for temporary representation only. During serialization datetime values are converted into strings. SQL/JSON requires writing timestamps with timezone in the same timezone offset as they were parsed. This is why we allow storage of timezone offset in JsonbValue struct. For the same reason timezone offset argument is added to JsonEncodeDateTime() function. Extracted from original patch by Nikita Glukhov, Teodor Sigaev, Oleg Bartunov. Revised by me.

* Add json(b)_to_tsvector functionTeodor Sigaev2018-04-07
| | | | | | | | | | | | | | | | Jsonb has a complex nature so there isn't best-for-everything way to convert it to tsvector for full text search. Current to_tsvector(json(b)) suggests to convert only string values, but it's possible to index keys, numerics and even booleans value. To solve that json(b)_to_tsvector has a second required argument contained a list of desired types of json fields. Second argument is a jsonb scalar or array right now with possibility to add new options in a future.

* Centralize json and jsonb handling of datetime typesAndrew Dunstan2018-01-16
| | | | | | | | | | | | | The creates a single function JsonEncodeDateTime which will format these data types in an efficient and consistent manner. This will be all the more important when we come to jsonpath so we don't have to implement yet more code doing the same thing in two more places. This also extends the code to handle time and timetz types which were not previously handled specially. This requires exposing the time2tm and timetz2tm functions. Patch from Nikita Glukhov

* Phase 3 of pgindent updates.Tom Lane2017-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | Don't move parenthesized lines to the left, even if that means they flow past the right margin. By default, BSD indent lines up statement continuation lines that are within parentheses so that they start just to the right of the preceding left parenthesis. However, traditionally, if that resulted in the continuation line extending to the right of the desired right margin, then indent would push it left just far enough to not overrun the margin, if it could do so without making the continuation line start to the left of the current statement indent. That makes for a weird mix of indentations unless one has been completely rigid about never violating the 80-column limit. This behavior has been pretty universally panned by Postgres developers. Hence, disable it with indent's new -lpl switch, so that parenthesized lines are always lined up with the preceding left paren. This patch is much less interesting than the first round of indent changes, but also bulkier, so I thought it best to separate the effects.

* Phase 2 of pgindent updates.Tom Lane2017-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change pg_bsd_indent to follow upstream rules for placement of comments to the right of code, and remove pgindent hack that caused comments following #endif to not obey the general rule. Commit e3860ffa4dd0dad0dd9eea4be9cc1412373a8c89 wasn't actually using the published version of pg_bsd_indent, but a hacked-up version that tried to minimize the amount of movement of comments to the right of code. The situation of interest is where such a comment has to be moved to the right of its default placement at column 33 because there's code there. BSD indent has always moved right in units of tab stops in such cases --- but in the previous incarnation, indent was working in 8-space tab stops, while now it knows we use 4-space tabs. So the net result is that in about half the cases, such comments are placed one tab stop left of before. This is better all around: it leaves more room on the line for comment text, and it means that in such cases the comment uniformly starts at the next 4-space tab stop after the code, rather than sometimes one and sometimes two tabs after. Also, ensure that comments following #endif are indented the same as comments following other preprocessor commands such as #else. That inconsistency turns out to have been self-inflicted damage from a poorly-thought-through post-indent "fixup" in pgindent. This patch is much less interesting than the first round of indent changes, but also bulkier, so I thought it best to separate the effects.

* Support JSON negative array subscripts everywhereAndrew Dunstan2015-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, there was an inconsistency across json/jsonb operators that operate on datums containing JSON arrays -- only some operators supported negative array count-from-the-end subscripting. Specifically, only a new-to-9.5 jsonb deletion operator had support (the new "jsonb - integer" operator). This inconsistency seemed likely to be counter-intuitive to users. To fix, allow all places where the user can supply an integer subscript to accept a negative subscript value, including path-orientated operators and functions, as well as other extraction operators. This will need to be called out as an incompatibility in the 9.5 release notes, since it's possible that users are relying on certain established extraction operators changed here yielding NULL in the event of a negative subscript. For the json type, this requires adding a way of cheaply getting the total JSON array element count ahead of time when parsing arrays with a negative subscript involved, necessitating an ad-hoc lex and parse. This is followed by a "conversion" from a negative subscript to its equivalent positive-wise value using the count. From there on, it's as if a positive-wise value was originally provided. Note that there is still a minor inconsistency here across jsonb deletion operators. Unlike the aforementioned new "-" deletion operator that accepts an integer on its right hand side, the new "#-" path orientated deletion variant does not throw an error when it appears like an array subscript (input that could be recognized by as an integer literal) is being used on an object, which is wrong-headed. The reason for not being stricter is that it could be the case that an object pair happens to have a key value that looks like an integer; in general, these two possibilities are impossible to differentiate with rhs path text[] argument elements. However, we still don't allow the "#-" path-orientated deletion operator to perform array-style subscripting. Rather, we just return the original left operand value in the event of a negative subscript (which seems analogous to how the established "jsonb/json #> text[]" path-orientated operator may yield NULL in the event of an invalid subscript). In passing, make SetArrayPath() stricter about not accepting cases where there is trailing non-numeric garbage bytes rather than a clean NUL byte. This means, for example, that strings like "10e10" are now not accepted as an array subscript of 10 by some new-to-9.5 path-orientated jsonb operators (e.g. the new #- operator). Finally, remove dead code for jsonb subscript deletion; arguably, this should have been done in commit b81c7b409. Peter Geoghegan and Andrew Dunstan

* Fix hstore_to_json_loose's detection of valid JSON number values.Andrew Dunstan2014-12-01
| | | | | | | | | | We expose a function IsValidJsonNumber that internally calls the lexer for json numbers. That allows us to use the same test everywhere, instead of inventing a broken test for hstore conversions. The new function is also used in datum_to_json, replacing the code that is now moved to the new function. Backpatch to 9.3 where hstore_to_json_loose was introduced.

* Introduce jsonb, a structured format for storing json.Andrew Dunstan2014-03-23
| | | | | | | | | | | | | | | | | | | | | | The new format accepts exactly the same data as the json type. However, it is stored in a format that does not require reparsing the orgiginal text in order to process it, making it much more suitable for indexing and other operations. Insignificant whitespace is discarded, and the order of object keys is not preserved. Neither are duplicate object keys kept - the later value for a given key is the only one stored. The new type has all the functions and operators that the json type has, with the exception of the json generation functions (to_json, json_agg etc.) and with identical semantics. In addition, there are operator classes for hash and btree indexing, and two classes for GIN indexing, that have no equivalent in the json type. This feature grew out of previous work by Oleg Bartunov and Teodor Sigaev, which was intended to provide similar facilities to a nested hstore type, but which in the end proved to have some significant compatibility issues.

* Clean up new JSON API typedefsPeter Eisentraut2013-07-20
| | | | | | | The new JSON API uses a bit of an unusual typedef scheme, where for example OkeysState is a pointer to okeysState. And that's not applied consistently either. Change that to the more usual PostgreSQL style where struct typedefs are upper case, and use pointers explicitly.

* Add new JSON processing functions and parser API.Andrew Dunstan2013-03-29
The JSON parser is converted into a recursive descent parser, and exposed for use by other modules such as extensions. The API provides hooks for all the significant parser event such as the beginning and end of objects and arrays, and providing functions to handle these hooks allows for fairly simple construction of a wide variety of JSON processing functions. A set of new basic processing functions and operators is also added, which use this API, including operations to extract array elements, object fields, get the length of arrays and the set of keys of a field, deconstruct an object into a set of key/value pairs, and create records from JSON objects and arrays of objects. Catalog version bumped. Andrew Dunstan, with some documentation assistance from Merlin Moncure.
