MySQL 5.5.39 Overview and Highlights
+1 Vote Up -0Vote Down

MySQL 5.5.39 was recently released (it is the latest MySQL 5.5, is GA), and is available for download here:

http://downloads.skysql.com/archive/index/p/mysql/v/5.5.39

This release, similar to the last 5.5 release, is mostly uneventful.

There were two “Functionality Added or Changed” and 24 bugs fixed.

The “Functionality Added or Changed” changes are:

  • CMake support was updated to handle CMake version 3.
  • The timed_mutexes system variable has no effect and is deprecated.

Out of the 24 …

Dealing with Assertion failure in file fut0lst.ic : addr.page == FIL_NULL || addr.boffset >= FIL_PAGE_DATA
+3 Vote Up -0Vote Down

I recently wrote an article on dealing with an assertion failure in log/log0recv.c, specifically !page || (ibool)!!page_is_comp(page) == dict_table_is_comp(index->table).

I mention it because this occurred after a system outage, and I just encountered another system outage (either HDD power outage or some other serious HDD event), with a completely different assertion failure and error message. Similar to the one above, it’s also kind of obscure, so I wanted to post this so people searching for it will find this.

For reference, the first outage assertion failure was this:

Added a Table of Contents

Not a big deal, but I just added a “Table of Contents” page to my blog to make finding older articles much easier.

I noticed most of my posts are quite lengthy, and it can take a bit of searching/clicking to find an older entry. So unless you happen to recall the ‘month/year’ it was published, which I don’t even remember that, then hopefully this will help.

Really simple, and looks just like this:

Dealing with Assertion failure in log/log0recv.c – !page || (ibool)!!page_is_comp(page) == dict_table_is_comp(index->table)
+4 Vote Up -0Vote Down

This is a somewhat uncommon error, so I wanted to take a moment and post the error and an explanation in order to make it easier for those who run into this in the future.

The main error is this (full pasted below):

InnoDB: Assertion failure in thread 139838283589376 in file log/log0recv.c line 1094
InnoDB: Failing assertion: !page || (ibool)!!page_is_comp(page) == dict_table_is_comp(index->table)

Basically, this is what it can look like after a power outage. In fact, this is the only time I have seen it, but I won’t say that it is the only way you could encounter it.

How do I deal with this, you ask?

Well, the above error shows that the …
