Upgrade Breakpad to latest
This commit will upgrade breakpad to version 1.0.86
(I9957f27cd134f862b9831e4b1d90f8a014eb37b6) from
https://chromium.googlesource.com/breakpad/breakpad
Added a script(BreakpadSwiftCleanup.sh) that remove files from Breakpad's
repository that are not used by Swift.
This commit also re-applies the changes that were introduced in commit
7f0fe603be200c09c74cf9cc295a972f3c3dbdfd, that change the minidump
filename format to include version and date
Test-Information:
https://travis-ci.org/google/breakpad/builds/283789304
https://ci.appveyor.com/project/vapier/breakpad/build/job/1bu73ysmcfpwg9e4
Tested by adding some code that forces a crash to the client on Windows 10
with VS2015. Verified the name and contents of the generated crash dump.

It +// has methods for logging at different levels and uses a log writer, a log +// formatter, and a log filter to get the job done. +// +// * log writer (GTMLogWriter) - Writes a given string to some log file, where +// a "log file" can be a physical file on disk, a POST over HTTP to some URL, +// or even some in-memory structure (e.g., a ring buffer). +// +// * log formatter (GTMLogFormatter) - Given a format string and arguments as +// a va_list, returns a single formatted NSString. A "formatted string" could +// be a string with the date prepended, a string with values in a CSV format, +// or even a string of XML. +// +// * log filter (GTMLogFilter) - Given a formatted log message as an NSString +// and the level at which the message is to be logged, this class will decide +// whether the given message should be logged or not. This is a flexible way +// to filter out messages logged at a certain level, messages that contain +// certain text, or filter nothing out at all. This gives the caller the +// flexibility to dynamically enable debug logging in Release builds. +// +// This file also declares some classes to handle the common log writer, log +// formatter, and log filter cases. Callers can also create their own writers, +// formatters, and filters and they can even build them on top of the ones +// declared here. Keep in mind that your custom writer/formatter/filter may be +// called from multiple threads, so it must be thread-safe. + +#import <Foundation/Foundation.h> +#import "GTMDefines.h" + +// Predeclaration of used protocols that are declared later in this file. +@protocol GTMLogWriter, GTMLogFormatter, GTMLogFilter; + +// GTMLogger +// +// GTMLogger is the primary user-facing class for an object-oriented logging +// system. It is built on the concept of log formatters (GTMLogFormatter), log +// writers (GTMLogWriter), and log filters (GTMLogFilter). When a message is +// sent to a GTMLogger to log a message, the message is formatted using the log +// formatter, then the log filter is consulted to see if the message should be +// logged, and if so, the message is sent to the log writer to be written out. +// +// GTMLogger is intended to be a flexible and thread-safe logging solution. Its +// flexibility comes from the fact that GTMLogger instances can be customized +// with user defined formatters, filters, and writers. And these writers, +// filters, and formatters can be combined, stacked, and customized in arbitrary +// ways to suit the needs at hand. For example, multiple writers can be used at +// the same time, and a GTMLogger instance can even be used as another +// GTMLogger's writer. This allows for arbitrarily deep logging trees. +// +// A standard GTMLogger uses a writer that sends messages to standard out, a +// formatter that smacks a timestamp and a few other bits of interesting +// information on the message, and a filter that filters out debug messages from +// release builds. Using the standard log settings, a log message will look like +// the following: +// +// 2007-12-30 10:29:24.177 myapp[4588/0xa07d0f60] [lvl=1] foo=<Foo: 0x123> +// +// The output contains the date and time of the log message, the name of the +// process followed by its process ID/thread ID, the log level at which the +// message was logged (in the previous example the level was 1: +// kGTMLoggerLevelDebug), and finally, the user-specified log message itself (in +// this case, the log message was @"foo=%@", foo). +// +// Multiple instances of GTMLogger can be created, each configured their own +// way. Though GTMLogger is not a singleton (in the GoF sense), it does provide +// access to a shared (i.e., globally accessible) GTMLogger instance. This makes +// it convenient for all code in a process to use the same GTMLogger instance. +// The shared GTMLogger instance can also be configured in an arbitrary, and +// these configuration changes will affect all code that logs through the shared +// instance. + +// +// Log Levels +// ---------- +// GTMLogger has 3 different log levels: Debug, Info, and Error. GTMLogger +// doesn't take any special action based on the log level; it simply forwards +// this information on to formatters, filters, and writers, each of which may +// optionally take action based on the level. Since log level filtering is +// performed at runtime, log messages are typically not filtered out at compile +// time. The exception to this rule is that calls to the GTMLoggerDebug() macro +// *ARE* filtered out of non-DEBUG builds. This is to be backwards compatible +// with behavior that many developers are currently used to. Note that this +// means that GTMLoggerDebug(@"hi") will be compiled out of Release builds, but +// [[GTMLogger sharedLogger] logDebug:@"hi"] will NOT be compiled out. +// +// Standard loggers are created with the GTMLogLevelFilter log filter, which +// filters out certain log messages based on log level, and some other settings. +// +// In addition to the -logDebug:, -logInfo:, and -logError: methods defined on +// GTMLogger itself, there are also C macros that make usage of the shared +// GTMLogger instance very convenient. These macros are: +// +// GTMLoggerDebug(...) +// GTMLoggerInfo(...) +// GTMLoggerError(...) +// +// Again, a notable feature of these macros is that GTMLogDebug() calls *will be +// compiled out of non-DEBUG builds*. +// +// Standard Loggers +// ---------------- +// GTMLogger has the concept of "standard loggers". A standard logger is simply +// a logger that is pre-configured with some standard/common writer, formatter, +// and filter combination. Standard loggers are created using the creation +// methods beginning with "standard". The alternative to a standard logger is a +// regular logger, which will send messages to stdout, with no special +// formatting, and no filtering. +// +// How do I use GTMLogger? +// ---------------------- +// The typical way you will want to use GTMLogger is to simply use the +// GTMLogger*() macros for logging from code. That way we can easily make +// changes to the GTMLogger class and simply update the macros accordingly. Only +// your application startup code (perhaps, somewhere in main()) should use the +// GTMLogger class directly in order to configure the shared logger, which all +// of the code using the macros will be using. Again, this is just the typical +// situation. +// +// To be complete, there are cases where you may want to use GTMLogger directly, +// or even create separate GTMLogger instances for some reason. That's fine, +// too. +// +// Examples +// -------- +// The following show some common GTMLogger use cases. +// +// 1. You want to log something as simply as possible. Also, this call will only +// appear in debug builds. In non-DEBUG builds it will be completely removed. +// +// GTMLoggerDebug(@"foo = %@", foo); +// +// 2. The previous example is similar to the following. The major difference is +// that the previous call (example 1) will be compiled out of Release builds +// but this statement will not be compiled out. +// +// [[GTMLogger sharedLogger] logDebug:@"foo = %@", foo]; +// +// 3. Send all logging output from the shared logger to a file. We do this by +// creating an NSFileHandle for writing associated with a file, and setting +// that file handle as the logger's writer. +// +// NSFileHandle *f = [NSFileHandle fileHandleForWritingAtPath:@"/tmp/f.log" +// create:YES]; +// [[GTMLogger sharedLogger] setWriter:f]; +// GTMLoggerError(@"hi"); // This will be sent to /tmp/f.log +// +// 4. Create a new GTMLogger that will log to a file. This example differs from +// the previous one because here we create a new GTMLogger that is different +// from the shared logger. +// +// GTMLogger *logger = [GTMLogger standardLoggerWithPath:@"/tmp/temp.log"]; +// [logger logInfo:@"hi temp log file"]; +// +// 5. Create a logger that writes to stdout and does NOT do any formatting to +// the log message. This might be useful, for example, when writing a help +// screen for a command-line tool to standard output. +// +// GTMLogger *logger = [GTMLogger logger]; +// [logger logInfo:@"%@ version 0.1 usage", progName]; +// +// 6. Send log output to stdout AND to a log file. The trick here is that +// NSArrays function as composite log writers, which means when an array is +// set as the log writer, it forwards all logging messages to all of its +// contained GTMLogWriters. +// +// // Create array of GTMLogWriters +// NSArray *writers = [NSArray arrayWithObjects: +// [NSFileHandle fileHandleForWritingAtPath:@"/tmp/f.log" create:YES], +// [NSFileHandle fileHandleWithStandardOutput], nil]; +// +// GTMLogger *logger = [GTMLogger standardLogger]; +// [logger setWriter:writers]; +// [logger logInfo:@"hi"]; // Output goes to stdout and /tmp/f.log +// +// For futher details on log writers, formatters, and filters, see the +// documentation below. +// +// NOTE: GTMLogger is application level logging. By default it does nothing +// with _GTMDevLog/_GTMDevAssert (see GTMDefines.h). An application can choose +// to bridge _GTMDevLog/_GTMDevAssert to GTMLogger by providing macro +// definitions in its prefix header (see GTMDefines.h for how one would do +// that). +// +@interface GTMLogger : NSObject { + @private + id<GTMLogWriter> writer_; + id<GTMLogFormatter> formatter_; + id<GTMLogFilter> filter_; +} + +// +// Accessors for the shared logger instance +// + +// Returns a shared/global standard GTMLogger instance.

It consists of two streams, each of them a vector 2-tuples. +// The OMAPTO stream contains tuples of the form +// +// (RVA in transformed image, RVA in original image) +// +// while the OMAPFROM stream contains tuples of the form +// +// (RVA in original image, RVA in transformed image) +// +// The entries in each vector are sorted by the first value of the tuple, and +// the lengths associated with a mapping are implicit as the distance between +// two successive addresses in the vector. + +// Consider a trivial 10-byte function described by the following symbol: +// +// Function: RVA 0x00001000, length 10, "foo" +// +// Now consider the same function, but with 5-bytes of instrumentation injected +// at offset 5. The OMAP streams describing this would look like: +// +// OMAPTO : [ [0x00001000, 0x00001000], +// [0x00001005, 0xFFFFFFFF], +// [0x0000100a, 0x00001005] ] +// OMAPFROM: [ [0x00001000, 0x00001000], +// [0x00001005, 0x0000100a] ] +// +// In this case the injected code has been marked as not originating in the +// source image, and thus it will have no symbol information at all. However, +// the injected code may also be associated with an original address range; +// for example, when prepending instrumentation to a basic block the +// instrumentation can be labelled as originating from the same source BB such +// that symbol resolution will still find the appropriate source code line +// number. In this case the OMAP stream would look like: +// +// OMAPTO : [ [0x00001000, 0x00001000], +// [0x00001005, 0x00001005], +// [0x0000100a, 0x00001005] ] +// OMAPFROM: [ [0x00001000, 0x00001000], +// [0x00001005, 0x0000100a] ] +// +// Suppose we asked DIA to lookup the symbol at location 0x0000100a of the +// instrumented image. It would first run this through the OMAPTO table and +// translate that address to 0x00001005. It would then lookup the symbol +// at that address and return the symbol for the function "foo". This is the +// correct result. +// +// However, if we query DIA for the length and address of the symbol it will +// tell us that it has length 10 and is at RVA 0x00001000. The location is +// correct, but the length doesn't take into account the 5-bytes of injected +// code. Symbol resolution works (starting from an instrumented address, +// mapping to an original address, and looking up a symbol), but the symbol +// metadata is incorrect. +// +// If we dump the symbols using DIA they will have their addresses +// appropriately transformed and reflect positions in the instrumented image. +// However, if we try to do a lookup using those symbols resolution can fail. +// For example, the address 0x0000100a will not map to the symbol for "foo", +// because DIA tells us it is at location 0x00001000 (correct) with length +// 10 (incorrect). The problem is one of order of operations: in this case +// we're attempting symbol resolution by looking up an instrumented address +// in the table of translated symbols. +// +// One way to handle this is to dump the OMAP information as part of the +// breakpad symbols. This requires the rest of the toolchain to be aware of +// OMAP information and to use it when present prior to performing lookup. The +// other option is to properly transform the symbols (updating length as well as +// position) so that resolution will work as expected for translated addresses. +// This is transparent to the rest of the toolchain. + +#include "common/windows/omap.h" + +#include <atlbase.h> + +#include <algorithm> +#include <cassert> +#include <set> + +#include "common/windows/dia_util.h" + +namespace google_breakpad { + +namespace { + +static const wchar_t kOmapToDebugStreamName[] = L"OMAPTO"; +static const wchar_t kOmapFromDebugStreamName[] = L"OMAPFROM"; + +// Dependending on where this is used in breakpad we sometimes get min/max from +// windef, and other times from algorithm.
