* Add Elf 32 Support to Courgette.dgarrett@chromium.org2011-11-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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.org2011-10-311-3/+3
| | | | | | | | | | | | | | | | 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). BUG=chromium-os:22149 TEST=Unittests Review URL: http://codereview.chromium.org/8417045 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@108019 0039d316-1c4b-4281-b951-d872f2087c98
* Further refactoring, move ImageInfo into Disassembler/DisassemblerWin32X86.dgarrett@chromium.org2011-10-261-3/+11
| | | | | | | | | | | | | | | | 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.org2011-10-211-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Code changes to get the code to compile under GCC.sra@google.com2009-07-181-5/+8
| | | | | | | | | | | | Courgette still only knows how to compress Windows x86 executables. But now you can compress them on linux. BUG=none TEST=none Review URL: http://codereview.chromium.org/149597 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@21042 0039d316-1c4b-4281-b951-d872f2087c98
* Improvements to Courgette's version of bsdiffsra@chromium.org2009-05-181-1/+1
| | | | | | | | | | | | | | * Store 'diff' bytes by run-length encoding zeros. This reduces the memory needed to store the zeros by ~30MB for chrome.7z. * Store the control tuple elements in separate streams. The 'extra_bytes' counts are often zero so this brings all the zeros together. The uncompressed patch file is much smaller due to the run-length encoded zeros. It is slightly smaller (3-8%) after compression with lzma.
