[Bug 12315] New: Shiny's Sacrifice (Demo): Too much swap / ulimit problem

http://bugs.winehq.org/show_bug.cgi?id=12315

Summary: Shiny's Sacrifice (Demo): Too much swap / ulimit problem
           Product: Wine
           Version: 0.9.58.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: loader
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Hi there,

I wanted to make some D3D/DDraw tests with the demo version of Shiny's
Sacrifice on a system where I don't have root access.

The problem is that the system has 512MB physical memory installed and 8GB of
swap configured. This is too much for Sacrifice and seems to trigger an (32bit
?) integer overflow.

The error message from Sacrifice is:
"Insufficient pagefile space. Please ensure that virtual memory is enabled and
that you have more than 128MB of disk space free on your pagefile drive before
running Sacrifice."

I did a search on Google for that problem and it also appears on Windows if the
system has a large amount of memory (or swap) installed, that triggers the
overflow.

So I was going to use ulimit -v to restrict memory usage by wine, but that does
not seem to work:

user@yui09:~/.wine/drive_c/Program Files/Shiny/Sacrifice Demo$ wine
"Sacrifice.exe"
preloader: Warning: failed to reserve range 00000000-60000000
wine: failed to initialize: /homes/user/local//lib/wine/ntdll.dll.so: failed to
map segment from shared object: Cannot allocate memory

I have tried values for ulimit -v of 64MB, 128MB, 256MB and up to 2GB. Always
the same problem with the preloader and the failed initialization.

Wine doesn't seem to respect the limits set by ulimit. I would really like to
make some tests on this system. Maybe someone can take a look at this ulimit
problem?

Greetings from Germany,
Tobias Jakobi

Tested demo available from here. 
http://cdn.gamezone.com/pub/gamezone/14/0/69/sacrificedemo.exe

This is definitely a dupe of bug 10844, I confirmed this by changing the value
at 0x158 from 04 to 03 which causes wine to limit the avail pagefile value,
after which the demo runs.

Which value? The value of the sacrifice executable at offset ...?

However wine should work with ulimit, right?

yes.

re ulimit, no, wine reads /proc/meminfo for GlobalMemoryStatus*.  Please mark
this as a duplicate of bug 10844.

Thanks to Jeff, marking this as a duplicate.

I still think that ulimits should be respected though.

I think you might misunderstand what ulimit is.  If you set certain limits,
described in the setrlimit linux man page, such as the maximum size of the
process's virtual memory, as would happen when using bash's builtin ulimit
command, requests for allocation of memory beyond the limit will fail.

It doesn't change the reporting of available memory, it would in most cases
lead to the offending process being terminated once it had requested enough
memory beyond the set limit.

Forgot to close this one.

Thanks to Jeff for the ulimit explanation! :-)
