From b384d6e4fff5ac56972f76321d3871e0786b114f Mon Sep 17 00:00:00 2001 From: Ed Lu Date: Tue, 4 Jun 2024 16:12:38 -0700 Subject: [PATCH 1/9] Added Breakpad crash dump generation Fixed compiling on Windows Make crash dump printing work better on Windows Tweaked Breakpad build Fixed Breakpad build for Godot 4 Switched to WINDOWS_ENABLED Removed some non buildable files listed in the files to build Ran clang format Fixed the other formatting issues detected by CI Removed a comment and added clarifying comment on crash dump message as to why it is printed twice on Windows Make an ugly string conversion to make Windows build work Tweaked the build configuration and formatted again removed lss Add lss properly Reinitialize breakpad after mono initialization on Linux otherwise the breakpad signal handlers are not active Disable Windows crash handler on destruction similarly to Linux Renamed breakpad_enabled to use_breakpad Forgot to wrap one piece of code inside ifdef USE_BREAKPAD Updated copyright years in the added files Fix register types for breakpad Fixed dir access Removed musl and elf_reader which was the only thing seemingly depending on it Updated header guards Removed the memdelete call --- COPYRIGHT.txt | 5 + SConstruct | 4 + main/main.cpp | 8 +- modules/breakpad/SCsub | 186 + modules/breakpad/breakpad.h | 48 +

Header file. + +Several funtions are included here, forming a complete set of +conversions between the three formats. UTF-7 is not included +here, but is handled in a separate source file. + +Each of these routines takes pointers to input buffers and output +buffers. The input buffers are const. + +Each routine converts the text between *sourceStart and sourceEnd, +putting the result into the buffer between *targetStart and +targetEnd. Note: the end pointers are *after* the last item: e.g. +*(sourceEnd - 1) is the last item. + +The return result indicates whether the conversion was successful, +and if not, whether the problem was in the source or target buffers. +(Only the first encountered problem is indicated.) + +After the conversion, *sourceStart and *targetStart are both +updated to point to the end of last text successfully converted in +the respective buffers. + +Input parameters: +sourceStart - pointer to a pointer to the source buffer. +The contents of this are modified on return so that +it points at the next thing to be converted. +targetStart - similarly, pointer to pointer to the target buffer. +sourceEnd, targetEnd - respectively pointers to the ends of the +two buffers, for overflow checking only. + +These conversion functions take a ConversionFlags argument. When this +flag is set to strict, both irregular sequences and isolated surrogates +will cause an error. When the flag is set to lenient, both irregular +sequences and isolated surrogates are converted. + +Whether the flag is strict or lenient, all illegal sequences will cause +an error return. This includes sequences such as: , , +or in UTF-8, and values above 0x10FFFF in UTF-32. Conformant code +must check for illegal sequences. + +When the flag is set to lenient, characters over 0x10FFFF are converted +to the replacement character; otherwise (when the flag is set to strict) +they constitute an error. + +Output parameters: +The value "sourceIllegal" is returned from some routines if the input +sequence is malformed.

(This is used to refer to things via + // global offset table entries, program linkage table entries, or + // other tricks used in position-independent code.) + // + // There are also two options that fall outside that matrix + // altogether: the pointer may be omitted, or it may have padding to + // align it on an appropriate address boundary.

In +// particular: +// +// - CompilationUnit calls Dwarf2Handler's member functions to report +// every attribute's value, regardless of what sort of DIE it is. +// As a result, the ProcessAttributeX functions end up looking like +// this: +// +// switch (parent_die_tag) { +// case DW_TAG_x: +// switch (attribute_name) { +// case DW_AT_y: +// handle attribute y of DIE type x +// ... +// } break; +// ... +// } +// +// In C++ it's much nicer to use virtual function dispatch to find +// the right code for a given case than to switch on the DIE tag +// like this. +// +// - Processing different kinds of DIEs requires different sets of +// data: lexical block DIEs have start and end addresses, but struct +// type DIEs don't. It would be nice to be able to have separate +// handler classes for separate kinds of DIEs, each with the members +// appropriate to its role, instead of having one handler class that +// needs to hold data for every DIE type. +// +// - There should be a separate instance of the appropriate handler +// class for each DIE, instead of a single object with tables +// tracking all the dies in the compilation unit. +// +// - It's not convenient to take some action after all a DIE's +// attributes have been seen, but before visiting any of its +// children. The only indication you have that a DIE's attribute +// list is complete is that you get either a StartDIE or an EndDIE +// call. +// +// - It's not convenient to make use of the tree structure of the +// DIEs. Skipping all the children of a given die requires +// maintaining state and returning false from StartDIE until we get +// an EndDIE call with the appropriate offset. +// +// This interface tries to take care of all that. (You're shocked, I'm sure.) +// +// Using the classes here, you provide an initial handler for the root +// DIE of the compilation unit. Each handler receives its DIE's +// attributes, and provides fresh handler objects for children of +// interest, if any. The three classes are: +// +// - DIEHandler: the base class for your DIE-type-specific handler +// classes. +// +// - RootDIEHandler: derived from DIEHandler, the base class for your +// root DIE handler class. +// +// - DIEDispatcher: derived from Dwarf2Handler, an instance of this +// invokes your DIE-type-specific handler objects. +// +// In detail: +// +// - Define handler classes specialized for the DIE types you're +// interested in. These handler classes must inherit from +// DIEHandler. Thus: +// +// class My_DW_TAG_X_Handler: public DIEHandler { ... }; +// class My_DW_TAG_Y_Handler: public DIEHandler { ... }; +// +// DIEHandler subclasses needn't correspond exactly to single DIE +// types, as shown here; the point is that you can have several +// different classes appropriate to different kinds of DIEs. +// +// - In particular, define a handler class for the compilation +// unit's root DIE, that inherits from RootDIEHandler: +// +// class My_DW_TAG_compile_unit_Handler: public RootDIEHandler { ... }; +// +// RootDIEHandler inherits from DIEHandler, adding a few additional +// member functions for examining the compilation unit as a whole, +// and other quirks of rootness. +// +// - Then, create a DIEDispatcher instance, passing it an instance of +// your root DIE handler class, and use that DIEDispatcher as the +// dwarf2reader::CompilationUnit's handler: +// +// My_DW_TAG_compile_unit_Handler root_die_handler(...); +// DIEDispatcher die_dispatcher(&root_die_handler); +// CompilationUnit reader(sections, offset, bytereader, &die_dispatcher); +// +// Here, 'die_dispatcher' acts as a shim between 'reader' and the +// various DIE-specific handlers you have defined. +// +// - When you call reader.Start(), die_dispatcher behaves as follows, +// starting with your root die handler and the compilation unit's +// root DIE: +// +// - It calls the handler's ProcessAttributeX member functions for +// each of the DIE's attributes. +// +// - It calls the handler's EndAttributes member function. This +// should return true if any of the DIE's children should be +// visited, in which case: +// +// - For each of the DIE's children, die_dispatcher calls the +// DIE's handler's FindChildHandler member function. If that +// returns a pointer to a DIEHandler instance, then +// die_dispatcher uses that handler to process the child, using +// this procedure recursively. Alternatively, if +// FindChildHandler returns NULL, die_dispatcher ignores that +// child and its descendants. +// +// - When die_dispatcher has finished processing all the DIE's +// children, it invokes the handler's Finish() member function, +// and destroys the handler. (As a special case, it doesn't +// destroy the root DIE handler.) +// +// This allows the code for handling a particular kind of DIE to be +// gathered together in a single class, makes it easy to skip all the +// children or individual children of a particular DIE, and provides +// appropriate parental context for each die. + +#ifndef COMMON_DWARF_DWARF2DIEHANDLER_H__ +#define COMMON_DWARF_DWARF2DIEHANDLER_H__ + +#include + +#include +#include + +#include "common/dwarf/types.h" +#include "common/dwarf/dwarf2enums.h" +#include "common/dwarf/dwarf2reader.h" +#include "common/using_std_string.h" + +namespace google_breakpad { + +// A base class for handlers for specific DIE types.

Thus, the row for func+0 +// describes the state before we allocate the stack frame. In the +// next row, the formula for computing the CFA has changed, +// reflecting that allocation. +// +// - The other entries are written in terms of the CFA; this allows +// them to remain unchanged as the stack pointer gets bumped around. +// For example, the rule for recovering the return address (the "ra" +// column) remains unchanged throughout the function, even as the +// stack pointer takes on three different offsets from the return +// address. +// +// - Although we haven't shown it, most calling conventions designate +// "callee-saves" and "caller-saves" registers. The callee must +// preserve the values of callee-saves registers; if it uses them, +// it must save their original values somewhere, and restore them +// before it returns. In contrast, the callee is free to trash +// caller-saves registers; if the callee uses these, it will +// probably not bother to save them anywhere, and the CFI will +// probably mark their values as "unrecoverable". +// +// (However, since the caller cannot assume the callee was going to +// save them, caller-saves registers are probably dead in the caller +// anyway, so compilers usually don't generate CFA for caller-saves +// registers.) +// +// - Exactly where the CFA points is a matter of convention that +// depends on the architecture and ABI in use. In the example, the +// CFA is the value the stack pointer had upon entry to the +// function, pointing at the saved return address. But on the x86, +// the call frame information generated by GCC follows the +// convention that the CFA is the address *after* the saved return +// address. +// +// But by definition, the CFA remains constant throughout the +// lifetime of the frame. This makes it a useful value for other +// columns to refer to. It is also gives debuggers a useful handle +// for identifying a frame. +// +// If you look at the table above, you'll notice that a given entry is +// often the same as the one immediately above it: most instructions +// change only one or two aspects of the stack frame, if they affect +// it at all. The DWARF format takes advantage of this fact, and +// reduces the size of the data by mentioning only the addresses and +// columns at which changes take place. So for the above, DWARF CFI +// data would only actually mention the following: +// +// insn cfa r0 r1 ... ra +// ======================================= +// func+0: sp cfa[0] +// func+1: sp+16 +// func+2: cfa[-4] +// func+11: sp+20 +// func+21: r0 +// func+22: sp +// +// In fact, this is the way the parser reports CFI to the consumer: as +// a series of statements of the form, "At address X, column Y changed +// to Z," and related conventions for describing the initial state. +// +// Naturally, it would be impractical to have to scan the entire +// program's CFI, noting changes as we go, just to recover the +// unwinding rules in effect at one particular instruction. To avoid +// this, CFI data is grouped into "entries", each of which covers a +// specified range of addresses and begins with a complete statement +// of the rules for all recoverable registers at that starting +// address. Each entry typically covers a single function. +// +// Thus, to compute the contents of a given row of the table --- that +// is, rules for recovering the CFA, RA, and registers at a given +// instruction --- the consumer should find the entry that covers that +// instruction's address, start with the initial state supplied at the +// beginning of the entry, and work forward until it has processed all +// the changes up to and including those for the present instruction. +// +// There are seven kinds of rules that can appear in an entry of the +// table: +// +// - "undefined": The given register is not preserved by the callee; +// its value cannot be recovered. +// +// - "same value": This register has the same value it did in the callee. +// +// - offset(N): The register is saved at offset N from the CFA. +// +// - val_offset(N): The value the register had in the caller is the +// CFA plus offset N. (This is usually only useful for describing +// the stack pointer.) +// +// - register(R): The register's value was saved in another register R. +// +// - expression(E): Evaluating the DWARF expression E using the +// current frame's registers' values yields the address at which the +// register was saved. +// +// - val_expression(E): Evaluating the DWARF expression E using the +// current frame's registers' values yields the value the register +// had in the caller. + +class CallFrameInfo { + public: + // The different kinds of entries one finds in CFI.

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.
