* Add Elf 32 Support to Courgette.dgarrett@chromium.org2011-11-081-8/+24
| | | | | | | | | | | | | | | | | | | | | | | | | This change takes advantage of recent refactoring and adds support for Elf X86 32 executables to courgette. It should have no effect on handling of Windows PE executables. We have planned ahead to be able to restrict the code size of the courgette library in different cases to reduce patcher sizes, but this change does not yet take advantage of that (all platforms are supported everywhere). Also, the patcher class currently contains a very small amount of Elf/PE specific code for recreating relocation tables that cannot (currently) be compiled out. BUG=chromium-os:22149 TEST=Please verify that Chrome/Chromium patches can still be generated and work. Also, please see how much the updater executable which is downloaded to users has changed in size since R16.

* Switch out use of std::string and std::vector for large allocations for a ↵tommi@chromium.org2011-04-061-20/+40
| | | | | | | | | | | | | | | | | buffer class that doesn't throw exceptions. The new buffer class is pretty simple and relies on the MemoryAllocator class that I previously to back large allocations with mapped files when memory is scarce. That reduced the number of crashes quite a bit but we still crash on machines that are simply out of diskspace as well. So, the right thing to do is to expect and handle failures which is what this cl is all about. What we should see once this has landed is that crash dumps due to courgette running out of disk space should disappear from crash/ and instead we should see the number of users that run into this particular problem in dashboards.

* Identifying call sites that need to handle out of memory situations in ↵tommi@chromium.org2011-03-221-16/+31
| | | | | | | | | | | | | | | | | Courgette. There's no functional change here, only interface changes: * Change methods that are known to fail out in the field to return bool instead of void. * Where those methods are called, check the return value and report errors * In debug builds use a specialized template class that forces callers to check return values (this is possible at compile time in gcc, but unfortunately not in VS). The next step will be to change the implementation to not use STL containers. TEST=Run courgette tests.
