Subject: E: Dynamic MMap ran out of room.

Date: Tue, 30 Jun 2009 20:22:35 +0200

Package: apt
Version: 0.7.21
Severity: wishlist

Hi,

the default dynamic MMap in apt is getting too small again. Since
ia32-apt-get adds i386 Packages.gz to the mix, thereby doubling the
number of packages, even a conservative sources.list results in:

Reading package lists... Error!
E: Dynamic MMap ran out of room. Please increase the size of APT::Cache-Limit. Current value: 25165824. (man 5 apt.conf)

I would welcome it if the default value could be increased again.

MfG
	Goswin

Subject: Close: E: Dynamic MMap ran out of room.

Version: 0.7.26~exp8

The error is gone as the MMap is now able to grow automatically
as needed at runtime on all architectures (by falling back to a char[]
on e.g. kfreebsd systems which do not have mremap).

  * apt-pkg/pkgcachegen.{cc,h}:
    - make the used MMap moveable (and therefore dynamic resizeable) by
      applying (some) mad pointer magic (Closes: #195018)
