LOCK_THREAD_COUNT
When using the performance schema file io instrumentation in MySQL 5.5,
a thread would loop forever inside lf_pinbox_put_pins, when disconnecting.
It would also hold LOCK_thread_count while doing so, effectively killing the
server.
The root cause of the loop in lf_pinbox_put_pins() is a leak of LF_PINS,
when used with the filename_hash LF_HASH table in the performance schema.
This fix contains the following changes:
1)
Added the missing call to lf_hash_search_unpin(), to prevent the leak.
2)
In mysys/lf_alloc-pin.c, there was some extra debugging code
(MY_LF_EXTRA_DEBUG) written to detect precisely this kind of issues,
but it was never used.
Replaced MY_LF_EXTRA_DEBUG with DBUG_OFF, so that leaks similar to this one
can be always detected in regular debug builds.
3)
Backported the fix for the following bug, from 5.6 to 5.5:
Bug#13417446 - 63339: INCORRECT FILE PATH IN PEFORMANCE_SCHEMA ON WINDOWS
Before this fix, a thread instrumented for the performance schema,
that would perform file io operations, could crash inside the LF_HASH
implementation, in cases when my_thread_init is not called.
The crash itself has not been reported in 5.5 but similar crashes have
been found in 5.6-based development branches, using LF_HASH for
more instrumentation.
The possibility of a crash in 5.5 is confirmed by code analysis.
The problem is that, when my_thread_init() is not called,
which can happen for threads in storage engines or thirs party code,
my_thread_var is NULL.
Using my_thread_var->stacks_ends_here in mysys/lf_alloc-pin.c is unsafe.
Given that my_thread_var is used:
- only for stacks_ends_here
- only on platform with HAVE_ALLOCA
- only when there is enough room on the stack
and given that the LF_HASH implementation has a fallback
algorythm implemented already when using alloca is not possible,
using my_thread_var->stacks_ends_here is in fact not a strict requirement,
and can be relaxed.
The fix is to:
- test explicitly if my_thread_var is NULL, to account for cases
when my_thread_init() is not used by the calling thread.
- not use alloca in this case, and rely on the fall back code already in place.
so that the LF_HASH can be supported even without my_thread_init().
The implementation of mysys/lf_alloc-pin.c has been fixed to support this new usage.
The units tests in unittest/mysys/lf-t.c have been adjusted accordingly.
Essentially, the problem is that safemalloc is excruciatingly
slow as it checks all allocated blocks for overrun at each
memory management primitive, yielding a almost exponential
slowdown for the memory management functions (malloc, realloc,
free). The overrun check basically consists of verifying some
bytes of a block for certain magic keys, which catches some
simple forms of overrun. Another minor problem is violation
of aliasing rules and that its own internal list of blocks
is prone to corruption.
Another issue with safemalloc is rather the maintenance cost
as the tool has a significant impact on the server code.
Given the magnitude of memory debuggers available nowadays,
especially those that are provided with the platform malloc
implementation, maintenance of a in-house and largely obsolete
memory debugger becomes a burden that is not worth the effort
due to its slowness and lack of support for detecting more
common forms of heap corruption.
Since there are third-party tools that can provide the same
functionality at a lower or comparable performance cost, the
solution is to simply remove safemalloc. Third-party tools
can provide the same functionality at a lower or comparable
performance cost.
The removal of safemalloc also allows a simplification of the
malloc wrappers, removing quite a bit of kludge: redefinition
of my_malloc, my_free and the removal of the unused second
argument of my_free. Since free() always check whether the
supplied pointer is null, redudant checks are also removed.
Also, this patch adds unit testing for my_malloc and moves
my_realloc implementation into the same file as the other
memory allocation primitives.
