Divide *level 1(detail)* log into *level 1(tuple level)* log and *level 2(detail)* log.

logs a little easier to read using the macro MYPRINTF() which calls myprintf().
|
|
Use macro MYLOG instead of function mylog in preparation for later changes and unify mylog() and inolog() using level parameter.
Enable the compiler to check the format string against the parameter of mylog() by adding __attribute__((format(printf,.,.))) to the declaration of mylog(GCC only).
Using this mechanism, check and fix many discordances of parameters.

Support the platforms e.g. FreeBSD which satisfies __STDC_UTF_16__ (but not satify __STDC_ISO_10646__) using mbrtoc16() and c16rtomb().
Use the functions bindpara_msg_to_utf8(), bindpara_wchar_to_msg(),
bindcol_hybrid_estimate(), bindcol_hybrid_exec(), bindcol_localize_estimate()
and bindcol_localize_exec() which hide the difference of platforms instead of
platform specific functions. They are implemented using already implemented
wstrtomsg(), msgtowstr(), wcs_to_utf8(), utf8_to_wcs_lf() and newly implemented
mbstoc16_lf(), c16tomsb(), ucs4_to_ucs2_lf(), ucs2_to_ucs4().
Add eucJP encoding case to wchar-char test.
[Minor changes]
Add conversion error check between unicode and the current locale.
Rename buf to send_buf in ResolveOneParam() so that grep or find can them find easily.
Separate "unicode_support.h" from "psqlodbc.h"
Change convert_linefeeds() from static to external.
Add AC_CHECK_FUNCS(mbrtoc16 c16rtomb) to Makefile.am.
Remove win_unicode.c from psqlsetup.vcxproj.

Check the lost connection
1. at the beginning of ODBC APIs.
2. at the beginning of FE-BE communications using extended protocol.

We haven't supported a segmented memory model for ages, probably never.
|
|
We no longer support ODBC 3.0, so these don't need to be separate anymore.
This removes some duplicated code at the bottom of each GetInfoAPI.

Older versions have been obsolete for a very long time by now. Removing the
support lets us get rid of a lot of code that no-one has in practice been
even compiling for a long time.

PostgreSQL added support for protocol version 3 in server version 7.4.
There's no need to support servers older than that. This simplifies the
code a lot, removing a lot of corner cases that haven't been properly
regression tested for a long time anyway.
Original patch by me, with some tweaks by Michael Paquier.

Make whitespace and indentation more consistent in SQL_API function
declarations.
|
|
This also changed the file permissions stored in git for a couple of header
files, removing the executable bit. Didn't realize they were different from
all the others, but apparently my editor decided to change them. Now
they're the same as all the other files, which seems good.

1. Remove pointlessly complicated AsyncThreads stuff. Instead use
_beginthread() to clean up threads.
2. Make pgenlist.dll from the structure change of ConnectionClass.
The driver dlls exports the functions described in connexp.h
which are used by pgenlist.dll.
3. Isolate the current communication path if necessary.
While an IAsyncPG object is alive, a ConnectionClass object (hereinafter
refered to as conn-obj) is assigned to it. The assignment has to be
changed in the following cases.
a) SQLDisconnect() is called for the current connection handle which
is assigned to an IAsyncPG object.
Allocate another conn-obj and move the current communication
path (*sock* member of the current conn-obj) to the new conn-obj.
The communicaation path is lost from the current conn-obj and
the new conn-obj is assigned to the IAsyncPG object.
b) Another (global) transaction is about to begin but the current
global transaction is not PREPARED yet.
Same as case a) but will open a new communication path for
the current conn-obj for the subsequent ODBC API calls.
c) Another (global) transaction is about to begin and the current
global transaction is already PREPARED.
Allocate another conn-obj and open a new communication path for
the conn-obj. The new conn-obj is assigned to the IAsyncPG
object only to issue COMMIT/ROLLBACK PREPARED command.
communication pass (*sock* member of the current ConnectionClass
object) to the new object and change the state of the current
object NOT CONNECTED. The IAsyncPG object uses new object instead
of the current object. In case b) the current object will open a
new communication path.
