* MDEV-9736: Window functions: multiple cursors to read filesort resultSergei Petrunia2016-09-241-14/+134
| | | | | | | | | | Add support for having multiple IO_CACHEs with type=READ_CACHE to share the file they are reading from. Each IO_CACHE keeps its own in-memory buffer. When doing a read or seek operation on the file, it notifies other IO_CACHEs that the file position has been changed. Make Rowid_seq_cursor use cloned IO_CACHE when reading filesort result.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Addreses are not necessarily between heap_start && heap_end. Malloc calls using mmap can place pointers outside these bounds. In this case, we'll warn the user that the query pointer is potentially invalid. However, we'll attempt to print the data anyway after we're done printing everything else.

| | | | * Bug#22897202: RPL_IO_THD_WAIT_FOR_DISK_SPACE HAS OCCASIONALSujatha Sivakumar2016-04-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FAILURES Analysis: ========= Test script is not ensuring that "assert_grep.inc" should be called only after 'Disk is full' error is written to the error log. Test checks for "Queueing master event to the relay log" state. But this state is set before invoking 'queue_event'. Actual 'Disk is full' error happens at a very lower level. It can happen that we might even reset the debug point before even the actual disk full simulation occurs and the "Disk is full" message will never appear in the error log. In order to guarentee that we must have some mechanism where in after we write "Disk is full" error messge into the error log we must signal the test to execute SSS and then reset the debug point. So that test is deterministic. Fix: === Added debug sync point to make script deterministic.
| | | | * BUG#22594514: HANDLE_FATAL_SIGNAL (SIG=11) INNisha Gopalakrishnan2016-03-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UNIQUE::~UNIQUE | SQL/UNIQUES.CC:355 Analysis ======== Enabling the sort_buffer_size with a large value can cause operations utilizing the sort buffer like DELETE as mentioned in the bug report to fail. 5.5 and 5.6 versions reports OOM error while in 5.7+, the server crashes. While initializing the mem_root for the sort buffer tree, the block size for the mem_root is determined from the 'sort_buffer_size' value. This unsigned long value is typecasted to unsigned int, hence it becomes zero. Further block_size computation while initializing the mem_root results in a very large block_size value. Hence while trying to allocate a block during the DELETE operation, an OOM error is reported. In case of 5.7+, the PFS instrumentation for memory allocation, overshoots the unsigned value and allocates a block of just one byte. While trying to free the block of the mem_root, the original block_size is used. This triggers the crash since the server tries to free unallocated memory. Fix: ==== In order to restrict usage of such unreasonable sort_buffer_size, the typecast of block size to 'unsigned int' is removed and hence reports OOM error across all versions for sizes exceeding unsigned int range.
| | | | * Bug#20685029: SLAVE IO THREAD SHOULD STOP WHEN DISK ISSujatha Sivakumar2016-03-012-7/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FULL Bug#21753696: MAKE SHOW SLAVE STATUS NON BLOCKING IF IO THREAD WAITS FOR DISK SPACE Problem: ======== Currently SHOW SLAVE STATUS blocks if IO thread waits for disk space. This makes automation tools verifying server health block on taking relevant action. Finally this will create SHOW SLAVE STATUS piles. Analysis: ========= SHOW SLAVE STATUS hangs on mi->data_lock if relay log write is waiting for free disk space while holding mi->data_lock. mi->data_lock is needed to protect the format description event (mi->format_description_event) which is accessed by the clients running FLUSH LOGS and slave IO thread. Note relay log writes don't need to be protected by mi->data_lock, LOCK_log is used to protect relay log between IO and SQL thread (see MYSQL_BIN_LOG::append_event). The code takes mi->data_lock to protect mi->format_description_event during relay log rotate which might get triggered right after relay log write. Fix: ==== Release the data_lock just for the duration of writing into relay log. Made change to ensure the following lock order is maintained to avoid deadlocks. data_lock, LOCK_log data_lock is held during relay log rotations to protect the description event.
| | | | * Bug#21770366 backport bug#21657078 to 5.5 and 5.6Jon Olav Hauglid2016-01-261-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Post-push fix: The problem was that condition variable timeouts could in some cases (slow machines and/or short timeouts) be infinite. When the number of milliseconds to wait is computed, the end time is computed before the now() time. This can result in the now() time being later than the end time, leading to negative timeout. Which after conversion to unsigned becomes ~infinite. This patch fixes the problem by explicitly checking if we get negative timeout and then using 0 if this is the case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The check inserts a DWARF directive to tell stack unwinding that the bottom of the (co-routine) stack has been reached. Without this, stack traces may attempt to continue past the bottom of the stack. The GCC version check was incorrect, and failed to trigger for GCC version 5.[0123].

These are needed to ensure that we have a constant thread_id used for debugging with a THD, even if it changes thread_id (=connection_id) - Set variables.pseudo_thread_id in constructor. Removed not needed sets.
