Most notes.xml files will be updated in every release and cause
the kind of the problems described in the previous commit.

Avoid hanging waiting for other processes on other node
to commit.
|
|
Fixed a race where some parts of a transaction could
be added to the checkpoint.
There are probably more races here but this improves the current
testcases.

We don't support communicating with such old nodes anyway.

* nm/mnesia_idx_insert_speedup/OTP-11103:
Fix missing case clause for ordered_set tables
Optimize index creation for Mnesia set tables
|
|
The previous commit contained a regression that would trigger a crash
when attempting to add an index to an Mnesia table of type ordered_set.
|
|
ETS bag tables have very poor performance on insertion if you have lots
of rows with duplicate keys, since it has to check each existing record
and make sure it's not inserting any duplicates. This can lead to some
pretty drastic slowdowns when inserting lots of rows into an Mnesia
table, IF you're introducing lots of duplicate values into an indexed
column.
As it turns out, we can fix this by switching to duplicate_bag tables
for storing Mnesia indexes on tables of type 'set', and it ultimately
makes no functional difference since we will never actually attempt to
insert any duplicate records anyway. (We would have to make some bigger
changes to make this work for Mnesia bag tables though, so that is left
as a possible enhancement for the future.)

If mnesia:cleartable/1 was called during a table_load an schema event
with delete and write of that table is sent, which caused the table
to contain the schema record instead of clearing the table.

* nox/enable-silent-rules/OTP-10726:
Implement ./otp_build configure --enable-silent-rules
|
|
|
|
With silent rules, the output of make is less verbose and compilation
warnings are easier to spot. Silent rules are disabled by default and
can be disabled or enabled at will by make V=0 and make V=1.

* ao/fix_mnesia_overload_msg_format:
Fix format of mnesia overload message
OTP-10639
|
|
Using ~p in mnesia overload message could lead to wrong messages.
mnesia_tm overload message contains a list of two numbers (queue length)
example:
instead of:
Mnesia is overloaded: {mnesia_tm,message_queue_len,[100,105]}
it prints :
Mnesia is overloaded: {mnesia_tm,message_queue_len,"di"}
Replacing ~p with ~w fixes the problem as it doesn't try
to detect lists of printable characters

timer:send_interval behaves badly when resuming from sleep on some
platforms. For example, if I sleep for 10 minutes, and have a
send_interval running once per minute, when I resume, 10 messages
will be sent immediately, eliminating the benefit of only running
the work periodically. This is admittedly a separate bug with
send_interval, but the workaround is straightforward, and also
protects from messages piling up in the queue when the work takes
longer than the interval.
This patch fixes piled up error reports on resume from sleep:
** WARNING ** Mnesia is overloaded: {dump_log, write_threshold}
You'll still be warned if mnesia is overloaded, just not repeatedly.
Additionally, erlang:send_after is more efficient than using the
timer module equivalent [1]

We have to ensure that we actually delete the last object with a
given (key, index) pair before removing the index.
|
|
table index
In case of bag tables, trying to delete a non-existing object leads to
the index becoming corrupt. This happens if the non-existing object we
try to delete happens to share its key and index field value with a single
existing object in the table.
Result: The index entry corresponding to the existing object is
removed.
