From eb07238e9c1a09a640dae06e8a433d7dba77f490 Mon Sep 17 00:00:00 2001 From: Thanos Doukoudakis Date: Mon, 16 Oct 2017 12:53:42 +0100 Subject: 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.

Commit your changes to your local repo and upload them to the server. + http://dev.chromium.org/developers/contributing-code + e.g. `git commit ... && git cl upload ...` + You will be prompted for credential and a description. + +4. At https://chromium-review.googlesource.com/ you'll find your issue listed; + click on it, then “Add reviewer”, and enter in the code reviewer.

The 4 main abstractions used in this file are the +// following: +// +// * logger (GTMLogger) - The main logging class that users interact with. 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 +#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= +// +// 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 writer_; + id formatter_; + id filter_; +} + +// +// Accessors for the shared logger instance +// + +// Returns a shared/global standard GTMLogger instance.

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.
