It turns out the reason we hadn't found out about the portability issues with our credential-control-message code is that almost no modern platforms use that code at all; the ones that used to need it now offer getpeereid(), which we choose first. The last holdout was NetBSD, and they added getpeereid() as of 5.0. So far as I can tell, the only live platform on which that code was being exercised was Debian/kFreeBSD, ie, FreeBSD kernel with Linux userland --- since glibc doesn't provide getpeereid(), we fell back to the control message code. However, the FreeBSD kernel provides a LOCAL_PEERCRED socket parameter that's functionally equivalent to Linux's SO_PEERCRED. That is both much simpler to use than control messages, and superior because it doesn't require receiving a message from the other end at just the right time. Therefore, add code to use LOCAL_PEERCRED when necessary, and rip out all the credential-control-message code in the backend. (libpq still has such code so that it can still talk to pre-9.1 servers ... but eventually we can get rid of it there too.) Clean up related autoconf probes, too. This means that libpq's requirepeer parameter now works on exactly the same platforms where the backend supports peer authentication, so adjust the documentation accordingly. |

Pavel Behal Revised by: Tatsuo Ishii Email: behal@opf.slu.cz Licence: The Same as PostgreSQL Sorry for my Eglish and C code, I'm not native :-) !!!!!!!!!!!!!!!!!!!!!!!!! NO WARRANTY !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Instalation: ------------ 1) Change three affected files in source directories (I don't have time to create proper patch diffs, I don't know how) [PostgreSQL 6.5.1$B$G$O$3$N%9%F%C%W$OI,MW$"$j$^$;$s!%(B-- $B@P0f(B] 2) Compile with enabled locale and multibyte set to LATIN2 3) Setup properly your instalation, do not forget to create locale variables in your profile (environment). Ex. (may not be exactly true): LC_ALL=cs_CZ.ISO8859-2 LC_COLLATE=cs_CZ.ISO8859-2 LC_CTYPE=cs_CZ.ISO8859-2 LC_MONETARY=cs_CZ.ISO8859-2 LC_NUMERIC=cs_CZ.ISO8859-2 LC_TIME=cs_CZ.ISO8859-2 4) You have to start the postmaster with locales set! 5) Try it with Czech language, it have to sort 5) Install ODBC driver for PgSQL into your M$ Windows 6) Setup properly your data source. Include this line in your ODBC configuration dialog in field "Connect Settings:" : SET CLIENT_ENCODING = 'WIN1250'; 7) Now try it again, but in Windows with ODBC. Description: ------------ - Depends on proper system locales, tested with RH6.0 and Slackware 3.6, with cs_CZ.iso8859-2 loacle - Never try to set-up server multibyte database encoding to WIN1250, always use LATIN2 instead. There is not WIN1250 locale in Unix - WIN1250 encoding is useable only for M$W ODBC clients. The characters are on thy fly re-coded, to be displayed and stored back properly Important: ---------- - it reorders your sort order depending on your LC_... setting, so don't be confused with regression tests, they don't use locale - "ch" is corectly sorted only in some newer locales (Ex. RH6.0) - you have to insert money as '162,50' (with comma in aphostrophes!) - not tested properly ------------------------------------------------------------------- $B;29M(B2$B!'(BSJIS$B%f!<%6Dj5AJ8;z(B (UDC) $B$r$I$&07$&$+$H8@$&$3$H$K$D$$$FCf>r$5$s(B (nak@email.com)$B$+$i$$$?$@$$$?LdBjDs5/$H2r@b$G$9!%(B -------------------------- $B0zMQ3+;O(B ---------------------------------- --- 1.
