2004-05-07Solve the 'Turkish problem' with undesirable locale behavior for caseTom Lane
conversion of basic ASCII letters. Remove all uses of strcasecmp and strncasecmp in favor of new functions pg_strcasecmp and pg_strncasecmp; remove most but not all direct uses of toupper and tolower in favor of pg_toupper and pg_tolower. These functions use the same notions of case folding already developed for identifier case conversion. I left the straight locale-based folding in place for situations where we are just manipulating user data and not trying to match it to built-in strings --- for example, the SQL upper() function is still locale dependent. Perhaps this will prove not to be what's wanted, but at the moment we can initdb and pass regression tests in Turkish locale.

2004-01-19Repair problem identified by Olivier Prenant: ALTER DATABASE SET search_pathTom Lane
should not be too eager to reject paths involving unknown schemas, since it can't really tell whether the schemas exist in the target database. (Also, when reading pg_dumpall output, it could be that the schemas don't exist yet, but eventually will.) ALTER USER SET has a similar issue. So, reduce the normal ERROR to a NOTICE when checking search_path values for these commands. Supporting this requires changing the API for GUC assign_hook functions, which causes the patch to touch a lot of places, but the changes are conceptually trivial.

2003-07-27Error message editing in utils/adt. Again thanks to Joe Conway for doingTom Lane
the bulk of the heavy lifting ...
2003-02-06Create a GUC variable REGEX_FLAVOR to control the type of regularTom Lane
expression accepted by the regex operators, per discussion yesterday. Along the way, reduce deadlock_timeout from PGC_POSTMASTER to PGC_SIGHUP category. It is probably best to insist that all backends share the same setting, but that doesn't mean it has to be frozen at startup.
2003-02-05Replace regular expression package with Henry Spencer's latest versionTom Lane
(extracted from Tcl 8.4.1 release, as Henry still hasn't got round to making it a separate library). This solves a performance problem for multibyte, as well as upgrading our regexp support to match recent Tcl and nearly match recent Perl.
2002-09-22Bring SIMILAR TO and SUBSTRING into some semblance of conformance withTom Lane
the SQL99 standard. (I'm not sure that the character-class features are quite right, but that can be fixed later.) Document SQL99 and POSIX regexps as being different features; provide variants of SUBSTRING for each.

2002-06-15Search the existing regular expression cache as a ring buffer.Thomas G. Lockhart
Will optimize the case for repeated calls for the same expression, which seems to be the most common case. Formerly, always searched from the first entry. May want to look at the least-recently-used algorithm to make sure it is identifying the right slots to reclaim. Seems silly to do math when it seems that we could simply use an incrementing counter...
2002-06-11Implement SQL99 OVERLAY(). Allows substitution of a substring in a string.Thomas G. Lockhart
Implement SQL99 SIMILAR TO as a synonym for our existing operator "~". Implement SQL99 regular expression SUBSTRING(string FROM pat FOR escape). Extend the definition to make the FOR clause optional. Define textregexsubstr() to actually implement this feature. Update the regression test to include these new string features. All tests pass. Rename the regular expression support routines from "pg95_xxx" to "pg_xxx". Define CREATE CHARACTER SET in the parser per SQL99. No implementation yet.

2000-07-07Fix misuse of StrNCpy to copy and add null to non-null-terminated data.Tom Lane
Does not work since it fetches one byte beyond the source data, and when the phase of the moon is wrong, the source data is smack up against the end of backend memory and you get SIGSEGV. Don't laugh, this is a fix for an actual user bug report.
2000-07-06Functions on 'text' type updated to new fmgr style. 'text' isTom Lane
now TOAST-able.
2000-07-05Update textin() and textout() to new fmgr style. This is just phaseTom Lane
one of updating the whole text datatype, but there are so dang many calls of these two routines that it seems worth a separate commit.
