From f279d3c43aa7536b0f9bf46df8f4a3ef02918be0 Mon Sep 17 00:00:00 2001 From: Andrei Elkin Date: Sat, 25 Nov 2017 18:54:42 +0200 Subject: MDEV-13073. This part converts the Ali patch`s identifiers to the MariaDB standard. Also some renaming is done as well as white spaces removal. --- sql/semisync_master.h | 134 +++++++++++++++++++++++++------------------------- 1 file changed, 67 insertions(+), 67 deletions(-) (limited to 'sql/semisync_master.h') diff --git a/sql/semisync_master.h b/sql/semisync_master.h index 737ad46dd27..97c5d01a1d5 100644 --- a/sql/semisync_master.h +++ b/sql/semisync_master.h @@ -27,18 +27,18 @@ extern PSI_mutex_key key_LOCK_binlog; extern PSI_cond_key key_COND_binlog_send; #endif -struct TranxNode { +struct Tranx_node { char log_name_[FN_REFLEN]; my_off_t log_pos_; - struct TranxNode *next_; /* the next node in the sorted list */ - struct TranxNode *hash_next_; /* the next node during hash collision */ + struct Tranx_node *next_; /* the next node in the sorted list */ + struct Tranx_node *hash_next_; /* the next node during hash collision */ }; /** - @class TranxNodeAllocator + @class Tranx_node_allocator This class provides memory allocating and freeing methods for - TranxNode.
