fix for bug: if a crash happened right after writing a REDO like this:
REDO - UNDO - REDO*, then recovery would ignore the last REDO* (ok),
rollback: REDO - UNDO - REDO* - REDO - CLR, and a next recovery would
thus execute REDO* instead of skipping it again. Recovery now logs
LOGREC_INCOMPLETE_GROUP when it meets REDO* for the first time,
to draw a boundary and ensure it is always skipped. Tested by hand.
Note: ma_test_all fails "maria_chk: error: Key 1 - Found too many records"
not due to this patch (failed before).
BitKeeper/triggers/post-commit:
no truncation of the commit mail, or how to review patches?
mysql-test/include/maria_verify_recovery.inc:
let caller choose the statement used to crash (sometimes we
want the crash to happen at special places)
mysql-test/t/maria-recovery.test:
user of maria_verify_recovery.inc now specifies statement which the
script should use for crashing.
storage/maria/ma_bitmap.c:
it's easier to search for all places using functions from the bitmap
module (like in ma_blockrec.c) if those exported functions all start
with "_ma_bitmap": renaming some of them.
Assertion that when we read a bitmap page, overwriting bitmap->map,
we are not losing information (i.e. bitmap->changed is false).
storage/maria/ma_blockrec.c:
update to new names. Adding code (disabled, protected by a #ifdef)
that I use to test certain crash scenarios (more to come).
storage/maria/ma_blockrec.h:
update to new names
storage/maria/ma_checkpoint.c:
update to new names
storage/maria/ma_extra.c:
update to new names
storage/maria/ma_loghandler.c:
new LOGREC_INCOMPLETE_GROUP
storage/maria/ma_loghandler.h:
new LOGREC_INCOMPLETE_GROUP
storage/maria/ma_recovery.c:
When at the end of the REDO phase we have identified some transactions
with incomplete REDO groups (REDOs without an UNDO or CLR_END),
for each of them we log LOGREC_INCOMPLETE_GROUP. This way, the
upcoming UNDO phase can write more records for such transaction,
a future recovery won't pair the incomplete group with the
CLR_END (as there is LOGREC_INCOMPLETE_GROUP to draw a boundary).
of bugfix made to maria_repair() yesterday.
Fail "bk delta" (and thus "bk citool") if an added or modified line
of a C/C++ file has white space at end of line
BitKeeper/triggers/pre-delta:
detection gave false alarm on added newline
storage/maria/ma_check.c:
propagation to maria_repair_by_sort() and maria_repair_parallel()
of bugfix made to maria_repair() yesterday. No effect now as
those two repair variants are never used with BLOCK_RECORD.

Showstopper and regression against 5.0.24.
Previously, we ignored seek() errors (see Bug#22828) and let seek()s
against pipes fail. Now, since we check that a seek didn't fail,
and return without reading, this bug popped up.
This restores the behavior for file-ish objects that could never be
seek()ed.
mysys/mf_iocache.c:
If we detect early that the file is not tell()able, then we should
assume that it's also not seek()able and therefore we should never
set the (poorly named) "seek_not_done" flag so that we don't immedi-
ately try to seek() when reading later.
The problem was that tell() was returning -1, so when we read later,
we needlessly tried to seek to position (unsigned long) -1 .
Also, if we think we're supposed to seek to a position in a file and
the file is un-tell()able, then abort.

Thirty five seconds is entirely too short of a period to wait for a server

give up after a very long period (arbitrarily chosen as 15 minutes).
In addition, if we're being asked to restart the server, then don't try
to start again if trying to stop the server failed.

Bits higher than 2**31 were impossible to set on THD::options. It's

Manual merge.
When only one row was present, the subtraction of nearly the same number
resulted in catastropic cancellation, introducing an error in the
VARIANCE calculation near 1e-15. That was sqrt()ed to get STDDEV, the
error was escallated to near 1e-8.
The simple fix of testing for a row count of 1 and forcing that to yield
0.0 is insufficient, as two rows of the same value should also have a
variance of 0.0, yet the error would be about the same.
So, this patch changes the formula that computes the VARIANCE to be one
that is not subject to catastrophic cancellation.
In addition, it now uses only (faster-than-decimal) floating point numbers
to calculate, and renders that to other types on demand.

sql/item_sum.cc:
Serg's suggestion: Force all VARIANCE calculations to be done with floating-
point types. It's faster, and the SQL standard says we may implement these
functions any way we want.
Additionally, use a form of variance calculation that is not subject to
catastrophic cancellation.
