Re: how can I use "pg_basebackup" and not include pg_log of master ?

[lin <jluwln@xxxxxxx>]

Can I modify "sendDir"  function to skip the log_direction (default is "pg_log") ?

the sendDir function is :

static int64

sendDir(char *path, int basepathlen, bool sizeonly, List *tablespaces)

{

DIR   *dir;

struct dirent *de;

char pathbuf[MAXPGPATH];

struct stat statbuf;

int64 size = 0;

dir = AllocateDir(path);

while ((de = ReadDir(dir, path)) != NULL)

{

/* Skip special stuff */

              if (strcmp(de->d_name, ".") == 0 || strcmp(de->d_name, "..") == 0)  

continue;

.......

--if (strcmp(de->d_name, ".") == 0 || strcmp(de->d_name, "..") == 0) 

++ if (strcmp(de->d_name, ".") == 0 || strcmp(de->d_name, "..") == 0 || strcmp(de->d_name, "pg_log"))    

Is there something wrong ? 

  Thanks,
