Re: innodb recovery tool - page parser and deleted rows

[Tuyra]

I find needed page files by in-file search. i can see the rows which i have been deleted. 

but constraints_parser can't parse all of them, only some of them. what causes it, any idea?

Hello,

i installed recovery tool and everything is fine. when i run the page_parser it parses all the data, everything is well.

i check the index id's with innodb_table_monitor, which table i had run "delete from table" query. the index id is 0-145 and there is no parsed files.

i can see my data in ibdata1 file when i open it with hex editor. but parser didn't parse this rows.

Where am I going wrong?

Thanks.

Hello, thanks for reply. 

I installed the latest bzr tree with fress installion. It parsed ibdata file to pages excellenly. But constraints_parser didn't parsed any rows. I copied the parsed pages and parsed rows on the 0.5 version, it parsed but not all rows again. 

Any ideas, thanks?

Do you specify -D option?
Show exact command you run and debug output.
For sake of simplicity try to fetch records from a single page only.

on the version 5.0, with -D  option or without it, it was parsing same data. but with 6.0 it worked perfect and parsed all data. 

i was trying to write regex patterns with java to parse page files. 

i'm trying to import database now.

thank you percona and all staff.
