Andrew Dunstan	5f8b4319b9	Use correct length to convert json unicode escapes. Bug reported on IRC - fix due to Andrew Gierth.	13 years ago
Andrew Dunstan	a570c98d7f	Add new JSON processing functions and parser API. 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.	13 years ago
Andrew Dunstan	38fb4d978c	JSON generation improvements. This adds the following: json_agg(anyrecord) -> json to_json(any) -> json hstore_to_json(hstore) -> json (also used as a cast) hstore_to_json_loose(hstore) -> json The last provides heuristic treatment of numbers and booleans. Also, in json generation, if any non-builtin type has a cast to json, that function is used instead of the type's output function. Andrew Dunstan, reviewed by Steve Singer. Catalog version bumped.	13 years ago
Bruce Momjian	bd61a623ac	Update copyrights for 2013 Fully update git head, and update back branches in ./COPYRIGHT and legal.sgml files.	13 years ago
Alvaro Herrera	c219d9b0a5	Split tuple struct defs from htup.h to htup_details.h This reduces unnecessary exposure of other headers through htup.h, which is very widely included by many files. I have chosen to move the function prototypes to the new file as well, because that means htup.h no longer needs to include tupdesc.h. In itself this doesn't have much effect in indirect inclusion of tupdesc.h throughout the tree, because it's also required by execnodes.h; but it's something to explore in the future, and it seemed best to do the htup.h change now while I'm busy with it.	13 years ago
Tom Lane	fa188b5ef5	Remove inappropriate semicolons after function definitions. Solaris Studio warns about this, and some compilers might think it's an outright syntax error.	14 years ago
Tom Lane	80edfd7659	Revisit error message details for JSON input parsing. Instead of identifying error locations only by line number (which could be entirely unhelpful with long input lines), provide a fragment of the input text too, placing this info in a new CONTEXT entry. Make the error detail messages conform more closely to style guidelines, fix failure to expose some of them for translation, ensure compiler can check formats against supplied parameters.	14 years ago
Tom Lane	f871ef74a5	Minor code review for json.c. Improve commenting, conform to project style for use of ++ etc. No functional changes.	14 years ago
Robert Haas	36b7e3da17	Mark JSON error detail messages for translation. Per gripe from Tom Lane.	14 years ago
Bruce Momjian	927d61eeff	Run pgindent on 9.2 source tree in preparation for first 9.3 commit-fest.	14 years ago
Tom Lane	3dd8e59681	Fix bogus handling of control characters in json_lex_string(). The original coding misbehaved if "char" is signed, and also made the extremely poor decision to print control characters literally when trying to complain about them. Report and patch by Shigeru Hanada. In passing, also fix core dump risk in report_parse_error() should the parse state be something other than what it expects.	14 years ago
Peter Eisentraut	f1f6737e15	Fix incorrect logic in JSON number lexer Detectable by gcc -Wlogical-op. Add two regression test cases that would previously allow incorrect values to pass.	14 years ago
Andrew Dunstan	0c9e5d5e0d	Correctly handle NULLs in JSON output. Error reported by David Wheeler.	14 years ago
Andrew Dunstan	6b044cb810	Fix typo, noticed by Will Crawford.	14 years ago
Andrew Dunstan	83fcaffea2	Fix a couple of cases of JSON output. First, as noted by Itagaki Takahiro, a datum of type JSON doesn't need to be escaped. Second, ensure that numeric output not in the form of a legal JSON number is quoted and escaped.	14 years ago
Andrew Dunstan	39909d1d39	Add array_to_json and row_to_json functions. Also move the escape_json function from explain.c to json.c where it seems to belong. Andrew Dunstan, Reviewd by Abhijit Menon-Sen.	14 years ago
Robert Haas	5384a73f98	Built-in JSON data type. Like the XML data type, we simply store JSON data as text, after checking that it is valid. More complex operations such as canonicalization and comparison may come later, but this is enough for not. There are a few open issues here, such as whether we should attempt to detect UTF-8 surrogate pairs represented as \uXXXX\uYYYY, but this gets the basic framework in place.	14 years ago
