* Add Elf 32 Support to Courgette.dgarrett@chromium.org2011-11-081-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Last small bit of refactoring.dgarrett@chromium.org2011-10-311-2/+2
| | | | | | | | | | | | | | | | Move the Win32X86Generator and Patcher classes to non-windows specific names since they can be reused untouched for Elf. Move them from one file to files with matching names while at it. Store the transformation kind on the generator class so that it can be know if it's PE or Elf. Unified the TransformationId and ExecutableType enums into a single enum used everywhere (defined in courgette.h since it's now part of the external API).

* Further refactoring, move ImageInfo into Disassembler/DisassemblerWin32X86.dgarrett@chromium.org2011-10-261-3/+1
| | | | | | | | | | | | | | | | This means that all PE specific knowledge is now contained in a single class which leaves us in pretty good shape for supporting ELF 32. There are still widespread assumptions about being 32 bit, but those can be addressed at a much later date.

* Start refactoring to reduce executable type knowledge.dgarrett@chromium.org2011-10-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This creates executable detection functions, a globally shared enum for describing an executable type, and reduces the number of classes and locations with executable specific knowledge. These changes, along with moving architecture specific classes into their own files should make it easier to produce special purpose clients that only contain the code required to apply their own form of patch. DisassemblerWin32EXE, ImagePE, CourgetteWin32X86PatchGenerator, and CourgetteWin32X86Patcher, and ensemble handling are all heavily affected here. This should have no effect on the behavior of the system yet, and is instead all prep-work. This is the same as an earlier CL, except that ParseHeader will now return an error for 64 bit PE executables, and resource only DLLs. This is because the detection factories depend on ParseHeader to decide if a given file is supported.

* Add a unittest for ensemble diffing.dgarrett@chromium.org2011-10-191-0/+1
| | | | | | | | | | | | | | | The courgette refactoring broke the ability to handle ensembles with 64 bit PE files, or resource only DLLs. This unittest handles patching ensembles that contain these file types to confirm my fix, and ensure I don't introduce this regression again.

That seems important, but I'm not sure how to do it without storing old client binaries in version control. Also refactors a number of unit tests to allow code sharing for reading files into memory.

* Force inclusion of build/common.gypi for all chromium gyp files.yaar@chromium.org2009-09-151-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | Why: Simpler build code. If everybody includes it, it should be included automatically. Why now: The webkit chromium builds need it be specified, since can't default to build/common.gypi. What was done: 1. build/common.gypi's contents were moved to a new file build/gyp_chromium.gypi 2. tools/gyp/gyp_chromium was moved to build/gyp_chromium and made to automatically include build/gyp_chromium.gypi. 3. lots of gyp files were fixed to not refer to build/common.gypi any more. 4. o3d which also builds independently of chrome, was fixed to have a gyp_o3d that includes gyp_chromium.gypi too. 5. build/common.gypi was left empty, because there are some external projects that still refer to it. Things that are left to do after this patch is in: 1. The following external files (in other repositories) need to stop include common.gypi ./third_party/hunspell/hunspell.gyp ./third_party/icu/icu.gyp ./v8/tools/gyp/v8.gyp 2. Once nobody refers to common.gypi anymore, delete common.gypi -or- Delete gyp_chromium.gypi and move its content back to common.gypi Tested on mac, win and linux. On win, got a few unit tests errors on chrome bookmarks, which should not be related. I'm running again with clobber to verify.
