The reason was that a couple of variables that hold number of rows that was used to calculate buffers was uint and caused an overflow.
Fixed by changing variables that could hold number of rows from uint to ulong and also added a cast for this test.
include/heap.h:
Reorder to get better alignment. Changed variables that could hold number of rows from uint to ulong
mysql-test/suite/heap/heap.result:
Added test case
mysql-test/suite/heap/heap.test:
Added test case
mysql-test/suite/plugins/t/server_audit.test:
Added sleep as we want to have disconnect logged before we try a new connect
storage/heap/ha_heap.cc:
Changed variables that could hold number of rows from uint to ulong
Limit number of rows to 4G (as most of the variables that holds rows are ulong anyway)
reset records_changed when key_stat_version is changed to not cause increments for every row changed
storage/heap/ha_heap.h:
changed records_changed to ulong as this can get big
storage/heap/hp_create.c:
Changed variables that could hold number of rows from uint to ulong
Added cast (fixed the original bug)
storage/heap/hp_delete.c:
Changed variables that could hold number of rows from uint to ulong
storage/heap/hp_open.c:
Removed not needed cast
storage/heap/hp_write.c:
Changed variables that could hold number of rows from uint to ulong
support-files/compiler_warnings.supp:
Removed extra : from supression
Allow "rpm -q --whatprovides mysql-server" to return more than one row.
(all rows should be identical though)
support-files/rpm/server-prein.sh:
don't use "head -1" or "uniq" to avoid introducing new dependencies.
"sed" is already used in this script.
don't use mysql-5.6 change.
correct fix: zero-out rounded tail after the number was shifted because
of the carry digit (otherwise the carry digit will be zeroed out too).
MDEV-5763 libmyodbc.so: undefined symbol: int2str
MDEV-5739 Symbol missing in libmysqlclient.so.18 (make_scrambled_password)
pam_mysql and especially myodbc need tons of internal symbols on Debian, argh!
Don't try to be smart about --socket.
Assume that if user has set up a non-standard location for a socket,
she did it consistently for both a server and clients
(otherwise most clients won't work anyway).
The RTLD_DEFAULT value on Labrador machine is not NULL,
so the dlsym() commands in the server_audit just fail
to bind the necessary functions.
Fixed by using RTLD_DEFAULT explicitly.
when compressed tables are used.
Analysis: Number of flushed pages is incorrectly calculated at
buf_do_LRU_batch. This leads to problem when utility function
flushes dirty blocks from the end of the flush list of
all buffer pool instances in a loop until enough pages are flushed
or time limit is reached. As number of flushed pages is incorrectly
calculated, the loop mostly try to flush until time limit is
reached because the number of pages limit is not reached.
Fix: Fix the calculation of flushed pages (very short). This fix
was provided by Alexey Stroganov (Percona).
In parallel replication, there was an error case where we could call
my_error() in-between events. This causes the assertion, as the previous event
has reported ok status, but the following event has not yet reset the
diagnostics area. This happened when a worker thread detects that the SQL
driver thread is aborting, and when it gets an error from a prior commit at
the same time in wait_for_prior_commit().
Since this is already an error case, the code should be using
unregister_wait_for_prior_commit() instead of wait_for_prior_commit(). But
unregister is already done a bit later (from finish_event_group()), so just
removing the redundant call to wait_for_prior_commit() fixes the issue.
- MDEV-5689 ExtractValue(xml, 'substring(/x,/y)') crashes
- MDEV-5709 ExtractValue() with XPath variable references returns wrong result.
Description:
1. The main problem was that that nodeset_func->fix_fields() was
called in Item_func_xml_extractvalue::val_str() and
Item_func_xml_update::val_str(), which led in some cases to
execution of the XPath engine *before* having a parsed XML value.
Moved to Item_xml_str_func::fix_fields().
2. Cleanup: added a new method Item_xml_str_func::fix_fields() and moved
most of the code from Item_xml_str_func::fix_length_and_dec()
to Item_xml_str_func::fix_fields(), to follow the usual Item layout.
3. Cleanup: a parsed XML value is useless without the raw XML value
it was built from.
Previously the parsed and the raw values where stored in separate String
instances. It was hard to follow how they are synchronized.
Added a helper class XML which contains both parsed and raw values.
Makes things easier to read and modify.
4. MDEV-5709: const_item() could incorrectly return a "true"
result when XPath expression contains users/SP variable references.
Now nodeset_func->const_item() is also taken into account to
catch such cases.
5. Minor code enhancements.
