* Change MDCVInfoELF into something usable.Ted Mielczarek2016-02-104-45/+313
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes MDCVInfoELF (which is currently unused, apparently a vestigal bit of code landed as part of Solaris support) into a supported CodeView format that simply contains a build id as raw bytes. Modern ELF toolchains support build ids nicely: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Developer_Guide/compiling-build-id.html It would be useful to have the original build ids of loaded modules in Linux minidumps, since tools like Fedora's darkserver allow querying by build id and the current Breakpad code truncates the build id to the size of a GUID, which loses information: https://darkserver.fedoraproject.org/ A follow-up patch will change the Linux minidump generation code to produce MDCVInfoELF in minidumps instead of MDCVInfoPDB70. This patch should be landed first to ensure that crash processors are able to handle this format before dumps are generated containing it. The full build id is exposed as the return value of Minidump::code_identifier(), which currently just returns "id" for modules in Linux dumps. For backwards-compatibility, Minidump::debug_identifier() continues to treat the build id as a GUID, so debug identifiers for existing modules will not change.

* Fix usage of deprecated method sendSynchronousRequest:returningResponse:error:.Sylvain Defresne2016-02-081-3/+43
| | | | | | | | | | | | | The method -[NSURLConnection sendSynchronousRequest:returningResponse:error:] has been deprecated in 10.11 OS X SDK and 9.0 iOS SDK without replacement. So emulate a synchronous request by using an asynchronous request and waiting on a semaphore for the request completion.

* Improvements to GYP buildPavel Labath2016-01-293-3/+10
| | | | | | | | | | | | | | | | | | | | | | This updates the GYP build for the processor component (on windows). - adds/removes references to files which were added or removed from the repository - includes build/common.gypi in the gyp files: needed to correctly detect the OS (I think, the generated MSVC solutions were broken without it) - conditionally compiles code platform-specific code for the given platform After this minidump processor nearly compiles with VS2013: the generated project is correct, but some files still have compilation errors.

* only build dump_syms_mac for x86 hostsMike Frysinger2016-01-274-27/+62
| | | | | | | | | | | | | | | | | | | The dump_syms_mac tool only works for the system it is being built for (it doesn't support running on ELFs for a diff target), and it builds only for x86 currently. If you look at the mac header: src/third_party/mac_headers/mach/machine/vm_types.h it will #error for non x86/arm systems, and the arm header is not in our source tree.

* test: stop building tons of copies of gtest/gmock objectsMike Frysinger2016-01-252-1667/+378
| | | | | | | | | | | | | | | | | | | | The current makefile ends up building ~17 copies of the gtest/gmock objects -- every test that refers to the cc files directly will have its own copy. This is because the build doesn't know if CFLAGS and such have changed between each target (and in some cases, they are). Create a new libtesting.a target to hold a single copy of these files and update all of the unittests to link that in. This speeds up the build a bit especially when you aren't using ccache. This does mean we can no longer build gtest/gmock with unique flags, but we haven't wanted that so far, so clearly no one wants that.

CL 1563223004 introduces two bugs on iOS. - Encoding the minidump name with extra percent causing crash server to fail processing the file. - Using a released pointer causing random crashes on upload.

It might be less efficient but this is probably less of an issue on SD cards. It is much better than not getting crash reports.
