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.
|
|
Give up to roll back 'internal' statements because the functionality is not effectively used.
Introduced 'external' instead of 'internal'.

SPRINTF_FIXED().

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.

Formerly the driver offered very simple bookmark support -- it is just
the current row number. Now the driver offers more verbose bookmarks which
contain KeySet informations (CTID (+ OID)). Though they consume 12bytes
(row number + CTID) or 16bytes (row number + CTID + OID), they are useful
in declare/fetch mode.
|
|
Now default isolation level is server's default instead of fixed SQL_TXN_READ_COMMITTED.
Also reduced the number of round trips using multiple commands.

A few were real bugs, although highly unlikely ones. Others were false
positives like dead code, but let's be tidy.
|
|
|
|
* Mark functions used only in same file as static.
* Remove unused 'encoding' argument from msgtowstr and wstrtoms (all
callers passed NULL).
* Silence remaining compiler warnings on 64-bit Windows about assigning
size_t to int without cast.
* Remove superfluous FORMAT_INT4/FORMAT_UINT4 defines.
* Remove useless dollar_quote argument from findTag (it was always '$'), and
add comment.
* Turn OID_NAME into a #define, to avoid a useless sprintf.
* Turn the mapFuncs array into structs, for clarity, and add comment.

It should be possible to call SQLSetConnectAttr to disable autocommit
before establishing a connection. It was incorrectly reset when the
per-datasource options were read. To fix, move autocommit_public flag from
ConnInfo struct to Connection, like we've always done with login_timeout.
Also add a test case.

Instead of speaking the frontend/backend protocol directly, use libpq's
functions for executing queries. This makes it libpq a hard dependency, but
removes direct dependencies to SSL and SSPI, and a lot of related code.
|
|
This seems more reliable.
Add a test case for SQLBulkOperations(SQL_FETCH_BY_BOOKMARK), although it's
disabled because it doesn't seem to work correctly (fetches wrong rows).
I don't have the energy to actually fix that now.

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.

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.

SQLSetStmtAttr() from (SQLUINTEGER *) to (SQLULEN *). This fixes the bug reported by Christopf Berg. Also verify similar attributes which were changed from SQL(U)INTEGER (*) to SQL(U)LEN (*) when 64bit ODBC was introduced.

cursor type which isn't supported, the driver should fall back to a
supported type, set an appropriate SQLState and return
SQL_SUCCESS_WITH_INFO.
Currently, if a SQL_ATTR_CURSOR_TYPE of SQL_CURSOR_DYNAMIC is requested,
we fall back to SQL_CURSOR_FORWARD_ONLY and no warning is given; this is
simply because we don't explicitly check for SQL_CURSOR_DYNAMIC.
A better solution is to check for SQL_CURSOR_DYNAMIC, fall back to
SQL_CURSOR_KEYSET_DRIVEN and set a warning accordingly.
Also, currently if SQL_CURSOR_KEYSET_DRIVEN is requested and only static
cursors are supported, we fall back without returning a warning.
