not converting event type when trying undelete

[n0099]

Run

sudo python2 ~/MyUndelete/MyUndelete.py -b binlog.000117 -s 148418658 -e 484776616

only gives me the following error in mysql error log:

[ERROR] [MY-010584] [Repl] Replica SQL: Could not execute Delete_rows event on table db.table; Can't find record in 'table', Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event's source log FIRST, end_log_pos 148425162, Error_code: MY-001032

but it's able to replace the event type with the original awk script in http://thenoyes.com/littlenoise/?p=307:

BEGIN { regexp = "$^" }

/^BINLOG/ {
  print;
  getline;
  regexp = "^" substr($0, 1, 5) "[CSiy][ABCD]" substr($0, 8, 4);
}

$0 ~ regexp {
  n = $0;
  $0 = substr(n, 1, 5)
  $0 = $0 substr("BRhx", index("CSiy", substr(n, 6, 1)), 1)
  $0 = $0 substr("4567", index("ABCD", substr(n, 7, 1)), 1)
  $0 = $0 substr(n, 8) ;
}

{ print; }

sudo mysqlbinlog --start-position=148418658 --stop-position=484776616 binlog.000117 | awk -f undelete.awk | mysql

[n0099]

and there's another warn by gawk KittyKatt/screenFetch#627 in the stdout of python2:

awk: cmd. line:1: warning: regexp escape sequence `\;' is not a known regexp operator

can be fix by change this line

MyUndelete/MyUndelete.py

Line 106 in 5ccd99c

c2 = ['awk', '/\/*!*\/\;/{flag=0}flag;/^BINLOG /{flag=1}']

to

- c2 = ['awk', '/\/*!*\/\;/{flag=0}flag;/^BINLOG /{flag=1}'] 
+ c2 = ['awk', '/\/*!*\/;/{flag=0}flag;/^BINLOG /{flag=1}']

I've find out some slideshow made by you about this approach to undelete:

Hello this is a very old program that I didn't maintain.
I do have in mind something better to handle this, but not much time.
