Detailed Description

The writer for a MINIDUMP_HANDLE_DATA_STREAM stream in a minidump and its contained MINIDUMP_HANDLE_DESCRIPTOR s.

As we currently do not track any data beyond what MINIDUMP_HANDLE_DESCRIPTOR supports, we only write that type of record rather than the newer MINIDUMP_HANDLE_DESCRIPTOR_2.

Note that this writer writes both the header (MINIDUMP_HANDLE_DATA_STREAM) and the list of objects (MINIDUMP_HANDLE_DESCRIPTOR), which is different from some of the other list writers.

Member Function Documentation

◆ Children()

std::vector< internal::MinidumpWritable * > crashpad::MinidumpHandleDataWriter::Children ( )

overrideprotectedvirtual

Returns the object’s children.

Note: Valid in kStateFrozen or any subsequent state.

Reimplemented from crashpad::internal::MinidumpWritable.

◆ Freeze()

bool crashpad::MinidumpHandleDataWriter::Freeze ( )

overrideprotectedvirtual

Transitions the object from kStateMutable to kStateFrozen.

The default implementation marks the object as frozen and recursively calls Freeze() on all of its children. Subclasses may override this method to perform processing that should only be done once callers have finished populating an object with data. Typically, a subclass implementation would call RegisterRVA() or RegisterLocationDescriptor() on other objects as appropriate, because at the time Freeze() runs, the in-memory locations of RVAs and location descriptors are known and will not change for the remaining duration of an object’s lifetime.

Returns: true on success. false on failure, with an appropriate message logged.

Reimplemented from crashpad::internal::MinidumpWritable.

◆ InitializeFromSnapshot()

void crashpad::MinidumpHandleDataWriter::InitializeFromSnapshot ( const std::vector< HandleSnapshot > & handle_snapshots )

Adds a MINIDUMP_HANDLE_DESCRIPTOR for each handle in handle_snapshot to the MINIDUMP_HANDLE_DATA_STREAM.

Parameters

[in] handle_snapshots The handle snapshots to use as source data.

Note: Valid in kStateMutable.

◆ SizeOfObject()

size_t crashpad::MinidumpHandleDataWriter::SizeOfObject ( )

overrideprotectedvirtual

Returns the amount of space that this object will consume when written to a minidump file, in bytes, not including any leading or trailing padding necessary to maintain proper alignment.

Note: Valid in kStateFrozen or any subsequent state.

Implements crashpad::internal::MinidumpWritable.

◆ StreamType()

MinidumpStreamType crashpad::MinidumpHandleDataWriter::StreamType ( ) const

overrideprotectedvirtual

Returns an object’s stream type.

Note: Valid in any state.

Implements crashpad::internal::MinidumpStreamWriter.

◆ WriteObject()

bool crashpad::MinidumpHandleDataWriter::WriteObject ( FileWriterInterface * file_writer )

overrideprotectedvirtual

Writes the object’s content.

Parameters

[in] file_writer The file writer to receive the object’s content.

Returns: true on success. false on error, indicating that the content could not be written to the minidump file.

Note: Valid in kStateWritable. The object will transition to kStateWritten after this method returns.

Implements crashpad::internal::MinidumpWritable.
