Nathan.qian updated SVN-4907:
-----------------------------
Environment: (was: We used svnlook to transform a dynamic library for
some of our interface operations. We found that memory leaks would occur when
svn_fs_node_id (with apr_pool_t and svn_pool_destroy(pool)) was called
frequently;
The code looks shown below， we call svn_fs_node_id with apr_pool_t , and after
the call , we use svn_pool_destroy(pool) clear memory. But there is a bug : if
we use a nonexistent path call subcommand_show_revison, the memory will leak
; but if a existing path, the memory is ok, no memory leak .
int init_svncmcenter(apr_pool_t *pool,char *out_str,const char
*repos_path,const char *path,const char **path_relative,const char *rev,struct
svnlook_opt_state *opt_state,svn_fs_root_t **root,const svn_fs_id_t
**id,svnlook_ctxt_t * *c,int with_lastexist )
{
......
......
if ((svn_fs_node_id(id, *root, *path_relative, pool)) != SVN_NO_ERROR || !(*id))
{
printf("path (%s) error. Warning: svn_fs_node_id may cause memory leaks.\n",
path);
sprintf(out_str,"212 path error");
return 212;
}
return 200;
}
int subcommand_show_revison(const char *repos_path,const char *path,const char
*rev,char *out_str,int b_filesize,int with_changed_date,int with_author)
{
apr_pool_t *pool = apr_allocator_owner_get(svn_pool_create_allocator(FALSE));
......

if (init_svncmcenter(pool,out_str, repos_path,
path,&path_relative,rev,&opt_state,&root,&id,&c,1) != 200)
{
