delete

Disable assignment.

Member Data Documentation

◆ m_active

bool Arch_Recv_Group_Info::m_active {false}

Group is active or not.

◆ m_durable

bool Arch_Recv_Group_Info::m_durable {false}

True if group is from durable archiving, false if left over from a crash during clone operation.

◆ m_file_start_index

uint Arch_Recv_Group_Info::m_file_start_index {std::numeric_limits<uint>::max()}

The file index which is part of the file name may not necessarily be 0 always.

It's possible that purge might have purged files in the group leading to the file index of the first file in the group being greater than 0. So we need this info to know the index of the first file in the group.

◆ m_group

Arch_Group* Arch_Recv_Group_Info::m_group {nullptr}

Group data.

◆ m_last_data_block

byte* Arch_Recv_Group_Info::m_last_data_block {nullptr}

Data block of the last reset file in a group.

◆ m_last_reset_block

byte* Arch_Recv_Group_Info::m_last_reset_block {nullptr}

Reset block of the last reset file in a group.

◆ m_last_reset_file

Arch_Reset_File Arch_Recv_Group_Info::m_last_reset_file

Reset file structure of the last reset file.

◆ m_last_stop_lsn

lsn_t Arch_Recv_Group_Info::m_last_stop_lsn {LSN_MAX}

Last stop LSN of the group if active, else end LSN.

◆ m_new_empty_file

bool Arch_Recv_Group_Info::m_new_empty_file {false}

True if a new empty file was present in the group directory.

This can happen in case of a crash while writing to a new file.

◆ m_num_files

uint Arch_Recv_Group_Info::m_num_files {0}

Number of archived files belonging to the group.

◆ m_reset_pos

Arch_Page_Pos Arch_Recv_Group_Info::m_reset_pos

Last reset position of the group.

◆ m_start_lsn

lsn_t Arch_Recv_Group_Info::m_start_lsn {LSN_MAX}

Start LSN of the group.

◆ m_write_pos

Arch_Page_Pos Arch_Recv_Group_Info::m_write_pos

Last write position of the group.
