Brian,

On tracing tsql, I found the segfault coming from line 874 in convert.c :

tds_strftime( whole_date_string, sizeof(whole_date_string),
tds_ctx->locale->date_fmt, &when );

due to tds_ctx being NULL at the time.

Subject: [freetds] RE: configure.in check for long long


Hi Brian,

I grabbed those changes and did a clean build on Tru64.
The build went ok, although it now tells me I have no type __int64,
and also that __int64 is of size 0. And that I have a long long.

Testing
-------

t0004 still fails

sqsh (and tsql) still take >30 seconds to make the connection.
In the all_types query, the _text entry still comes up empty or garbage

Querying my simple "Changes" table works from sqsh, but from tsql it dumps
core, as follows:

 Segmentation fault at [tds_convert_datetime:6 +0x1c60,0x3ffbffef6a0]

Running a "select @@version" from tsql works ok.

Sorry I can't look further into this just now but I'm due somewhere else...

David

Hi all,

I've added a check for long, long long, and __int64 to configure.in and 
made the typedef in tds.h.in a substituted value based on that.

If there is no 64bit integer type on the box we default to whatever "long" 
is, so there is a potential for buffer overflows where the size of 
TDS_INT8 is assumed within the code, so I've added a HAVE_INT64 macro such 
that we can test for that and handle it gracefully (although I haven't 
modified any of the mainline code to check it yet).  Thinking about it, I 
maybe should have made the unsupported value "double" so the sizes matched 
anyway, not sure.

So, based on this and jkl's HAVE_ATOLL fixes, Tru64 should work again (I 
think).

We can turn off certain features if 64bit ints aren't supported on a 
platform (like support for SYBINT8 datatypes under TDS 8.0, or some types 
of money conversions even), but I would hope we can at least compile and 
run without crashing.

Brian

PS tsql was broken from the convert changes, i fixed it too.
