Detailed Description

A ProcessSnapshot based on a minidump file.

Member Function Documentation

◆ AnnotationsSimpleMap()

const std::map< std::string, std::string > & crashpad::ProcessSnapshotMinidump::AnnotationsSimpleMap ( ) const
overridevirtual

Returns key-value string annotations recorded for the process, system, or snapshot producer.

This method retrieves annotations recorded for a process. 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.”

Annotations stored here may reflect the process, system, or snapshot producer. Most annotations not under the client’s direct control will be retrievable by this method. For clients such as Chrome, this includes the product name and version.

Additional per-module annotations may be obtained by calling ModuleSnapshot::AnnotationsSimpleMap().

Implements crashpad::ProcessSnapshot.

◆ ClientID()

void crashpad::ProcessSnapshotMinidump::ClientID ( UUID client_id) const
overridevirtual

Returns a UUID identifying the client that the snapshot represents.

Client identification is within the scope of the application, but it is expected that the identifier will be unique for an instance of Crashpad monitoring an application or set of applications for a user. The identifier shall remain stable over time.

If no identifier is available, this field will contain zeroes.

Implements crashpad::ProcessSnapshot.

◆ CustomMinidumpStreams()

std::vector< const MinidumpStream * > crashpad::ProcessSnapshotMinidump::CustomMinidumpStreams ( ) const

Returns a list of custom minidump streams. This routine is the equivalent of ModuleSnapshot::CustomMinidumpStreams(), except that in a minidump it is impossible to associate a custom stream to a specific module.

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

◆ Exception()

const ExceptionSnapshot * crashpad::ProcessSnapshotMinidump::Exception ( ) const
overridevirtual

Returns an ExceptionSnapshot reflecting the exception that the snapshot process sustained to trigger the snapshot being taken.

Returns
An ExceptionSnapshot object. The caller does not take ownership of this object, it is scoped to the lifetime of the ProcessSnapshot object that it was obtained from. If the snapshot is not a result of an exception, returns nullptr.

Implements crashpad::ProcessSnapshot.

◆ ExtraMemory()

std::vector< const MemorySnapshot * > crashpad::ProcessSnapshotMinidump::ExtraMemory ( ) const
overridevirtual

Returns a vector of additional memory blocks that should be included in a minidump.

Returns
An vector of MemorySnapshot objects that will be included in the crash dump. The caller does not take ownership of these objects, they are scoped to the lifetime of the ProcessSnapshot object that they were obtained from.

Implements crashpad::ProcessSnapshot.

◆ Handles()

std::vector< HandleSnapshot > crashpad::ProcessSnapshotMinidump::Handles ( ) const
overridevirtual

Returns HandleSnapshot objects reflecting the open handles in the snapshot process at the time of the snapshot.

Returns
A vector of HandleSnapshot objects.

Implements crashpad::ProcessSnapshot.

◆ Initialize()

bool crashpad::ProcessSnapshotMinidump::Initialize ( FileReaderInterface file_reader)

Initializes the object.

Parameters
[in]file_readerA file reader corresponding to a minidump file. The file reader must support seeking.
Returns
true if the snapshot could be created, false otherwise with an appropriate message logged.

◆ Memory()

const ProcessMemory * crashpad::ProcessSnapshotMinidump::Memory ( ) const
overridevirtual

Returns a ProcessMemory object that allows accessing the process' memory directly.

Returns
A ProcessMemory object. The caller does not take ownership of this object, it is scoped to the lifetime of the ProcessSnapshot object that it was obtained from.

Implements crashpad::ProcessSnapshot.

◆ MemoryMap()

std::vector< const MemoryMapRegionSnapshot * > crashpad::ProcessSnapshotMinidump::MemoryMap ( ) const
overridevirtual

Returns MemoryMapRegionSnapshot objects reflecting the regions of the memory map in the snapshot process at the time of the snapshot.

Returns
A vector of MemoryMapRegionSnapshot objects. The caller does not take ownership of these objects, they are scoped to the lifetime of the ProcessSnapshot object that they were obtained from.

Implements crashpad::ProcessSnapshot.

◆ Modules()

std::vector< const ModuleSnapshot * > crashpad::ProcessSnapshotMinidump::Modules ( ) const
overridevirtual

Returns ModuleSnapshot objects reflecting the code modules (binary images) loaded into the snapshot process at the time of the snapshot.

Returns
A vector of ModuleSnapshot objects. The caller does not take ownership of these objects, they are scoped to the lifetime of the ProcessSnapshot object that they were obtained from.

Implements crashpad::ProcessSnapshot.

◆ ProcessCPUTimes()

void crashpad::ProcessSnapshotMinidump::ProcessCPUTimes ( timeval *  user_time,
timeval *  system_time 
) const
overridevirtual

Returns the snapshot process’ CPU usage times in user_time and system_time.

Parameters
[out]user_timeThe time that the process has spent executing in user mode.
[out]system_timeThe time that the process has spent executing in system (kernel) mode.

Implements crashpad::ProcessSnapshot.

◆ ProcessStartTime()

void crashpad::ProcessSnapshotMinidump::ProcessStartTime ( timeval *  start_time) const
overridevirtual

Returns the time that the snapshot process was started in start_time.

Normally, process uptime in wall clock time can be computed as SnapshotTime()ProcessStartTime(), but this cannot be guaranteed in cases where the real-time clock has been set during the snapshot process’ lifetime.

Parameters
[out]start_timeThe time that the process was started.

Implements crashpad::ProcessSnapshot.

◆ ReportID()

void crashpad::ProcessSnapshotMinidump::ReportID ( UUID client_id) const
overridevirtual

Returns a UUID identifying the event that the snapshot describes.

This provides a stable identifier for a crash even as the report is converted to different formats, provided that all formats support storing a crash report ID. When a report is originally created, a report ID should be assigned. From that point on, any operations involving the same report should preserve the same report ID.

If no identifier is available, this field will contain zeroes.

Implements crashpad::ProcessSnapshot.

◆ SnapshotTime()

void crashpad::ProcessSnapshotMinidump::SnapshotTime ( timeval *  snapshot_time) const
overridevirtual

Returns the time that the snapshot was taken in snapshot_time.

Parameters
[out]snapshot_timeThe time that the snapshot was taken. This is distinct from the time that a ProcessSnapshot object was created or initialized, although it may be that time for ProcessSnapshot objects representing live or recently-crashed process state.

Implements crashpad::ProcessSnapshot.

◆ System()

const SystemSnapshot * crashpad::ProcessSnapshotMinidump::System ( ) const
overridevirtual

Returns a SystemSnapshot reflecting the characteristics of the system that ran the snapshot process at the time of the snapshot.

Returns
A SystemSnapshot object. The caller does not take ownership of this object, it is scoped to the lifetime of the ProcessSnapshot object that it was obtained from.

Implements crashpad::ProcessSnapshot.

◆ Threads()

std::vector< const ThreadSnapshot * > crashpad::ProcessSnapshotMinidump::Threads ( ) const
overridevirtual

Returns ThreadSnapshot objects reflecting the threads (lightweight processes) existing in the snapshot process at the time of the snapshot.

Returns
A vector of ThreadSnapshot objects. The caller does not take ownership of these objects, they are scoped to the lifetime of the ProcessSnapshot object that they were obtained from.

Implements crashpad::ProcessSnapshot.

◆ UnloadedModules()

std::vector< UnloadedModuleSnapshot > crashpad::ProcessSnapshotMinidump::UnloadedModules ( ) const
overridevirtual

Returns UnloadedModuleSnapshot objects reflecting the code modules the were recorded as unloaded at the time of the snapshot.

Returns
A vector of UnloadedModuleSnapshot objects.

Implements crashpad::ProcessSnapshot.
