Re: [PATCH] Optimize json_lex_string by batching character copying

[Zhihong Yu]

Hi,
Looking at the patch,

+           if (copyable_characters_length)
+           {
+               /* flush copyable characters */
+               appendBinaryStringInfo(
+                                      lex->strval,
+                                      s - copyable_characters_length,
+                                      copyable_characters_length);
+
+           }
            break;

I wonder why copyable_characters_length is not reset after flushing.

Cheers
