Particularly in attached bug browser process can't allocate 250Mb to accept data from renderer Mapping smaller blocks is workaround.

* The correct type for the size of a chunk of memory is size_t.cevans@chromium.org2013-01-101-2/+8
| | | | | | | | | | | | | | | | | | By using uint32, we have bugs on 64-bit platforms: callers passing in a size_t, will have their size truncated, potentially allocating a smaller chunk than requested. There are a few places this happens, including on the receiving ends of IPCs(!) However, coversely, other callers of the API might directly assign the memory chunk's length to uint32, leading to a different possible truncation problem. This is guaraded against by limiting operations internally to std::numeric_limits<uint32_t> in size for now. There's some minor cascade effects that make the CL look larger than it is.

* Advertise a minimum alignment for SharedMemory::Map().dalecurtis@chromium.org2012-08-181-0/+2
| | | | | | | | | | | | | | | | | No real changes, just adds a DCHECK() and unit test for a minimum alignment that callers can count on from Map(). Map() is already returning addresses which are aligned to the platform page size. Necessary for a media use case in which a wrapped shared memory object is passed around and is expected to have a certain alignment. BUG=none TEST=unittests, try bots.

* Give base::SharedMemory::CreateAnonymous an executable flagmcgrathr@chromium.org2011-12-011-12/+8
| | | | | | | | | | | | | | | | | | | | | NaCl on Mac and Linux needs to create a shared memory object that it can later make executable with mprotect. Express this need in the interface it uses. Add a test that pages mapped from such an object can later be passed to mprotect with PROT_EXEC. This lays the groundwork for a later change that will sometimes use a different method to allocate an object on Linux when it needs to be executable. On some Linux distributions, shm_open yields objects whose mappings cannot be made executable.

* POSIX: Transfer network data using shared memoryagl@chromium.org2009-02-111-0/+9
| | | | | | | | | | | | | | | | | | | | | | This patch adds the long planned support for sharing memory on POSIX by transporting file descriptors. It largely builds on the shared memory cleanup work by jrg. We move FileDescriptor out of chrome/common/file_descriptor_posix.h and into base/file_descriptor_posix.h. Since all that's left in the chrome/common verion is the DescriptorSet, those files are renamed to descriptor_set.[h|cc]. The SharedMemoryHandle on POSIX then becomes a typedef to a FileDescriptor and thus can be serialised over IPC. After that, it's mostly a case of cleaning up those snippets of code which considered SharedMemoryHandles to be scaler values.
