Detailed Description

A ModuleSnapshot of a code module (binary image) loaded into a running (or crashed) process on a Windows system.

Member Function Documentation

◆ AnnotationObjects()

std::vector< AnnotationSnapshot > crashpad::internal::ModuleSnapshotWin::AnnotationObjects ( ) const

overridevirtual

Returns the typed annotation objects recorded in the module.

This method retrieves annotations recorded in a module. These annotations are intended for diagnostic use, including crash analysis. Annotation objects are strongly-typed name-value pairs. The names are not unique.

For macOS snapshots, these annotations are found by interpreting the __DATA,crashpad_info section as CrashpadInfo. Clients can use the Crashpad client interface to store annotations in this structure. Most annotations under the client’s direct control will be retrievable by this method. For clients such as Chrome, this includes the process type.

The annotations returned by this method do not duplicate those returned by AnnotationsVector() or AnnotationsSimpleMap().

Implements crashpad::ModuleSnapshot.

◆ AnnotationsSimpleMap()

std::map< std::string, std::string > crashpad::internal::ModuleSnapshotWin::AnnotationsSimpleMap ( ) const

overridevirtual

Returns key-value string annotations recorded in the module.

This method retrieves annotations recorded in a module. These annotations are intended for diagnostic use, including crash analysis. “Simple annotations” are structured as a sequence of key-value pairs, where all keys and values are strings. These are referred to in Chrome as “crash keys.”

For macOS snapshots, these annotations are found by interpreting the __DATA,crashpad_info section as CrashpadInfo. Clients can use the Crashpad client interface to store annotations in this structure. Most annotations under the client’s direct control will be retrievable by this method. For clients such as Chrome, this includes the process type.

The annotations returned by this method do not duplicate those returned by AnnotationsVector() or AnnotationObjects(). Additional annotations related to the process, system, or snapshot producer may be obtained by calling ProcessSnapshot::AnnotationsSimpleMap().

Implements crashpad::ModuleSnapshot.

◆ AnnotationsVector()

std::vector< std::string > crashpad::internal::ModuleSnapshotWin::AnnotationsVector ( ) const

overridevirtual

Returns string annotations recorded in the module.

This method retrieves annotations recorded in a module. These annotations are intended for diagnostic use, including crash analysis. A module may contain multiple annotations, so they are returned in a vector.

For macOS snapshots, these annotations are found by interpreting the module’s __DATA,__crash_info section as crashreporter_annotations_t. System libraries using the crash reporter client interface may reference annotations in this structure. Additional annotations messages may be found in other locations, which may be module-specific. The dynamic linker (dyld) can provide an annotation at its _error_string symbol.

The annotations returned by this method do not duplicate those returned by AnnotationsSimpleMap() or AnnotationObjects().

Implements crashpad::ModuleSnapshot.

◆ BuildID()

std::vector< uint8_t > crashpad::internal::ModuleSnapshotWin::BuildID ( ) const

overridevirtual

Returns the module’s build ID.

On ELF platforms, the build ID is a variable-length byte stream that identifies a library uniquely, and is usually used to look up its debug symbols when stored separately. This will return an empty vector if it is unsupported.

BuildID() and UUIDAndAge() are never available in the same place. When UUIDAndAge() is unavailable, it will be filled out with the contents of BuildID() (either 0-padded or truncated) and age will be zero.

See also: UUIDAndAge()

Implements crashpad::ModuleSnapshot.

◆ CustomMinidumpStreams()

std::vector< const UserMinidumpStream * > crashpad::internal::ModuleSnapshotWin::CustomMinidumpStreams ( ) const

overridevirtual

Returns a list of custom minidump stream specified in the module to be included in the crash dump.

Returns: The caller does not take ownership of the returned objects, they are scoped to the lifetime of the ModuleSnapshot object that they were obtained from.

Implements crashpad::ModuleSnapshot.

◆ DebugFileName()

std::string crashpad::internal::ModuleSnapshotWin::DebugFileName ( ) const

overridevirtual

Returns the module’s debug file info name.

On Windows, this references the PDB file, which contains symbol information held separately from the module itself. On other platforms, this is normally the basename of the module, because the debug info file’s name is not relevant even in split-debug scenarios.

See also: UUIDAndAge()

Implements crashpad::ModuleSnapshot.

◆ FileVersion()

void crashpad::internal::ModuleSnapshotWin::FileVersion	(	uint16_t *	version_0,
		uint16_t *	version_1,
		uint16_t *	version_2,
		uint16_t *	version_3
	)		const

overridevirtual

Returns the module’s file version in the version_* parameters.

If no file version can be determined, the version_* parameters are set to 0.

For macOS snapshots, this is taken from the module’s LC_ID_DYLIB load command for shared libraries, and is 0 for other module types.

Implements crashpad::ModuleSnapshot.

◆ GetCrashpadOptions()

void crashpad::internal::ModuleSnapshotWin::GetCrashpadOptions ( CrashpadInfoClientOptions * options )

Returns options from the module's CrashpadInfo structure.

Parameters

[out] options Options set in the module's CrashpadInfo structure.

◆ Initialize()

bool crashpad::internal::ModuleSnapshotWin::Initialize	(	ProcessReaderWin *	process_reader,
		const ProcessInfo::Module &	process_reader_module
	)

Initializes the object.

Parameters

[in]	process_reader	A ProcessReaderWin for the process containing the module.
[in]	process_reader_module	The module within the ProcessReaderWin for which the snapshot should be created.

Returns: true if the snapshot could be created, false otherwise with an appropriate message logged.

◆ Size()

uint64_t crashpad::internal::ModuleSnapshotWin::Size ( ) const

overridevirtual

Returns the size that the module occupies in the snapshot process’ address space, starting at its base address.

For macOS snapshots, this method only reports the size of the __TEXT segment, because segments may not be loaded contiguously.

Implements crashpad::ModuleSnapshot.

◆ SourceVersion()

void crashpad::internal::ModuleSnapshotWin::SourceVersion	(	uint16_t *	version_0,
		uint16_t *	version_1,
		uint16_t *	version_2,
		uint16_t *	version_3
	)		const

overridevirtual

Returns the module’s source version in the version_* parameters.

If no source version can be determined, the version_* parameters are set to 0.

For macOS snapshots, this is taken from the module’s LC_SOURCE_VERSION load command.

Implements crashpad::ModuleSnapshot.

◆ Timestamp()

time_t crashpad::internal::ModuleSnapshotWin::Timestamp ( ) const

overridevirtual

Returns the module’s timestamp, if known.

The timestamp is typically the modification time of the file that provided the module in time_t format, seconds since the POSIX epoch. If the module’s timestamp is unknown, this method returns 0.

Implements crashpad::ModuleSnapshot.

◆ UUIDAndAge()

void crashpad::internal::ModuleSnapshotWin::UUIDAndAge	(	crashpad::UUID *	uuid,
		uint32_t *	age
	)		const

overridevirtual

Returns the module’s UUID in the uuid parameter, and the age of that UUID in age.

A snapshot module’s UUID is taken directly from the module itself. If the module does not have a UUID, the uuid parameter will be zeroed out.

age is the number of times the UUID has been reused. This occurs on Windows with incremental linking. On other platforms age will always be 0.
