* Update copyright for 2014Bruce Momjian2014-01-07
| | | | | Update all files in head, and files COPYRIGHT and legal.sgml in all back branches.
* Properly detect invalid JSON numbers when generating JSON.Andrew Dunstan2013-12-27
| | | | | | | | | | | Instead of looking for characters that aren't valid in JSON numbers, we simply pass the output string through the JSON number parser, and if it fails the string is quoted. This means among other things that money and domains over money will be quoted correctly and generate valid JSON. Fixes bug #8676 reported by Anderson Cristian da Silva. Backpatched to 9.2 where JSON generation was introduced.
* Use cstring_to_text_with_len when length is known.Robert Haas2013-11-18
| | | | | | This avoids a potentially-expensive extra call to strlen(). David Rowley
* Fix whitespace issues found by git diff --check, add gitattributesPeter Eisentraut2013-11-10
| | | | | Set per file type attributes in .gitattributes to fine-tune whitespace checks. With the associated cleanups, the tree is now clean for git
* Get rid of more cases of the "must detoast before output function" meme.Tom Lane2013-11-03
| | | | | I missed that json.c was doing this too, because for some bizarre reason it wasn't doing it adjacent to the output function call.
* json_typeof function.Andrew Dunstan2013-10-10
| | | | Andrew Tipton.
* Message punctuation and pluralization fixesPeter Eisentraut2013-08-09

* 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.
* Avoid reading past datum end when parsing JSON.Noah Misch2013-06-12
| | | | | | | Several loops in the JSON parser examined a byte in memory just before checking whether its address was in-bounds, so they could read one byte beyond the datum's allocation. A SIGSEGV is possible. New in 9.3, so no back-patch.
* Fix unescaping of JSON Unicode escapes, especially for non-UTF8.Andrew Dunstan2013-06-12
| | | | | | | | | | Per discussion on -hackers. We treat Unicode escapes when unescaping them similarly to the way we treat them in PostgreSQL string literals. Escapes in the ASCII range are always accepted, no matter what the database encoding. Escapes for higher code points are only processed in UTF8 databases, and attempts to process them in other databases will result in an error. \u0000 is never unescaped, since it would result in an impermissible null byte.
* Handle Unicode surrogate pairs correctly when processing JSON.Andrew Dunstan2013-06-08
| | | | | | | | | | | | | In 9.2, Unicode escape sequences are not analysed at all other than to make sure that they are in the form \uXXXX. But in 9.3 many of the new operators and functions try to turn JSON text values into text in the server encoding, and this includes de-escaping Unicode escape sequences. This processing had not taken into account the possibility that this might contain a surrogate pair to designate a character outside the BMP. That is now handled correctly. This also enforces correct use of surrogate pairs, something that is not done by the type's input routines. This fact is noted in the docs.
* pgindent run for release 9.3Bruce Momjian2013-05-29
| | | | | This is the first run of the Perl-based pgindent script. Also update pgindent instructions.
* Use correct length to convert json unicode escapes.Andrew Dunstan2013-05-01
| | | | Bug reported on IRC - fix due to Andrew Gierth.
* 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.
* JSON generation improvements.Andrew Dunstan2013-03-10
| | | | | | | | | | | | | | | | | | 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.
* Update copyrights for 2013Bruce Momjian2013-01-01
| | | | | Fully update git head, and update back branches in ./COPYRIGHT and legal.sgml files.
* Split tuple struct defs from htup.h to htup_details.hAlvaro Herrera2012-08-30
| | | | | | | | | | | | 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.
* Remove inappropriate semicolons after function definitions.Tom Lane2012-06-30
| | | | | Solaris Studio warns about this, and some compilers might think it's an outright syntax error.
* Revisit error message details for JSON input parsing.Tom Lane2012-06-13
| | | | | | | | | 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.
* Minor code review for json.c.Tom Lane2012-06-12
| | | | | Improve commenting, conform to project style for use of ++ etc. No functional changes.
* Mark JSON error detail messages for translation.Robert Haas2012-06-12
| | | | Per gripe from Tom Lane.
* Run pgindent on 9.2 source tree in preparation for first 9.3Bruce Momjian2012-06-10
| | | | commit-fest.
* Fix bogus handling of control characters in json_lex_string().Tom Lane2012-06-04
| | | | | | | | | 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.
* Fix incorrect logic in JSON number lexerPeter Eisentraut2012-05-20
| | | | | | | Detectable by gcc -Wlogical-op. Add two regression test cases that would previously allow incorrect values to pass.
* Correctly handle NULLs in JSON output.Andrew Dunstan2012-02-23
| | | | Error reported by David Wheeler.
* Fix typo, noticed by Will Crawford.Andrew Dunstan2012-02-21
|
* Fix a couple of cases of JSON output.Andrew Dunstan2012-02-20
| | | | | | 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.
* Add array_to_json and row_to_json functions.Andrew Dunstan2012-02-03
| | | | | | | Also move the escape_json function from explain.c to json.c where it seems to belong. Andrew Dunstan, Reviewd by Abhijit Menon-Sen.
* Built-in JSON data type.Robert Haas2012-01-31
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.
