* Use new overflow aware integer operations.Andres Freund2017-12-12
| | | | | | | | | | | | | | | | | A previous commit added inline functions that provide fast(er) and correct overflow checks for signed integer math. Use them in a significant portion of backend code. There's more to touch in both backend and frontend code, but these were the easily identifiable cases. The old overflow checks are noticeable in integer heavy workloads. A secondary benefit is that getting rid of overflow checks that rely on signed integer overflow wrapping around, will allow us to get rid of -fwrapv in the future. Which in turn slows down other code. Author: Andres Freund Discussion: https://postgr.es/m/20171024103954.ztmatprlglz3rwke@alap3.anarazel.de

* Make sure chr(int) can't create invalid UTF8 sequences.Tom Lane2014-05-16
| | | | | | | | | | | | | | | | | | Several years ago we changed chr(int) so that if the database encoding is UTF8, it would interpret its argument as a Unicode code point and expand it into the appropriate multibyte sequence. However, we weren't sufficiently careful about checking validity of the input. According to RFC3629, UTF8 disallows code points above U+10FFFF (note that the predecessor standard RFC2279 was more liberal). Also, both versions of the UTF8 spec agree that Unicode surrogate-pair codes should never appear in UTF8. Because our encoding validity checks follow RFC3629, our failure to enforce these restrictions in chr() means it could be used to produce text strings that will be rejected when the database is dumped and reloaded. To ensure consistency with the input functions, let's actually apply pg_utf8_islegal() to the proposed output of chr(). Per discussion, this seems like too much of a behavioral change to back-patch, but it's not too late to squeeze it into 9.4.

* Simplify and standardize conversions between TEXT datums and ordinary CTom Lane2008-03-25
| | | | | | | | | | | | | | | | | | | | strings. This patch introduces four support functions cstring_to_text, cstring_to_text_with_len, text_to_cstring, and text_to_cstring_buffer, and two macros CStringGetTextDatum and TextDatumGetCString. A number of existing macros that provided variants on these themes were removed. Most of the places that need to make such conversions now require just one function or macro call, in place of the multiple notational layers that used to be needed. There are no longer any direct calls of textout or textin, and we got most of the places that were using handmade conversions via memcpy (there may be a few still lurking, though). This commit doesn't make any serious effort to eliminate transient memory leaks caused by detoasting toasted text objects before they reach text_to_cstring. We changed PG_GETARG_TEXT_P to PG_GETARG_TEXT_PP in a few places where it was easy, but much more could be done. Brendan Jurd and Tom Lane

* Close previously open holes for invalidly encoded data to enter theAndrew Dunstan2007-09-18
| | | | | | | | | | | | | | | | | | | | | database via builtin functions, as recently discussed on -hackers. chr() now returns a character in the database encoding. For UTF8 encoded databases the argument is treated as a Unicode code point. For other multi-byte encodings the argument must designate a strict ascii character, or an error is raised, as is also the case if the argument is 0. ascii() is adjusted so that it remains the inverse of chr(). The two argument form of convert() is gone, and the three argument form now takes a bytea first argument and returns a bytea. To cover this loss three new functions are introduced: . convert_from(bytea, name) returns text - converts the first argument from the named encoding to the database encoding . convert_to(text, name) returns bytea - converts the first argument from the database encoding to the named encoding . length(bytea, name) returns int - gives the length of the first argument in characters in the named encoding
* Replace direct assignments to VARATT_SIZEP(x) with SET_VARSIZE(x, len).Tom Lane2007-02-27
| | | | | | | | | | | Get rid of VARATT_SIZE and VARATT_DATA, which were simply redundant with VARSIZE and VARDATA, and as a consequence almost no code was using the longer names. Rename the length fields of struct varlena and various derived structures to catch anyplace that was accessing them directly; and clean up various places so caught. In itself this patch doesn't change any behavior at all, but it is necessary infrastructure if we hope to play any games with the representation of varlena headers. Greg Stark and Tom Lane

Also, revert my earlier change to move installation path mashing from Makefile.global to configure. Turns out not to work well because configure script is working with unexpanded variables, and so fails to match in cases where it should match.
