Fix typo 2019-03-29 20:16:26 -07:00
Evan Tschannen a44ffd851e fix: the shared tlog could fail to update a stopped tlog’s queueCommitVersion to version if a second tlog registered before it could issue the first commit for the tlog 2019-03-29 20:11:30 -07:00
Evan Tschannen b6008558d3 renamed BinaryWriter.toStringRef() to .toValue(), because the function now returns a Standalone<StringRef>()

eliminated an unnecessary copy from buffered peek cursor

Evan Tschannen 1c6ad6d307 fix: change the location where stopped is checked, because a yield could cause cause stopped to be set after the existing check 2019-03-20 19:33:09 -07:00
Alex Miller b11ecb3210 Remove random bits of code that were either unneeded or leftover from debugging. 2019-03-18 15:47:20 -07:00
Alex Miller 37ea71b117 Implement limiting how many bytes recovery will read.
This time, track what location in the DiskQueue has been spilled in
persistent state, and then feed it back into the disk queue before
recovery.

This also introduces an ASSERT that recovery only reads exactly the
bytes that it needs to have in memory.

Alex Miller 29ab7370cd Clear versionLocation when spilling, and pop DQ separately.
Popping the disk queue now requires potentially recovering the location
to which we can pop from the spilled data itself, and for each tag we
must maintain the first location with relevant data.

The previous queue we had to represent the ordering, queueOrder, was
used by spilling, and popped when a TLog had been spilled.  This means
that as soon as a TLog has been fully spilled, we have no idea how it
relates in order to other fully spilled TLogs.

Instead, use queueOrder to keep track of all the TLog UIDs until they're
removed, and use spillOrder to keep track of the order only for
spilling.

Alex Miller 7f5bc2981f Checksum DiskQueue pages on read, but at a lower priority.
If a server has its data spilled, then it's behind the 5s window.
Feeding it data is less important than committing, so we can hide the
extra CPU usage from checksumming the read amplified disk queue pages.

Alex Miller ee4721a63f Make checking or ignoring checksums part of the IDiskQueue::read API. 2019-03-15 21:01:18 -07:00
Alex Miller 81c59e88a8 Persist the protocol version of a TLog instance when it is created.
This allows us to do easy upgrades of SpilledData in the future, if the
need arises, because we then have a protocol version to compare against.

Alex Miller 686b097397 Remove verification code from DiskQueue and TLogServer. 2019-03-15 21:01:15 -07:00
Alex Miller 77f596743f Bump persistFormat in TLogServer to differ from OldTLogServer*
Though this format is being deprecated in favor of an eventual plumbing
through of TLogVersion, we should probably bump it anyway.

And also remove the fallback to OldTLogServer code.  It should never be
executed, as OldTLogServer_6_0 is entirely relied upon to execute
OldTLogServer_4_6.

Alex Miller c6a65389ae Remove noexcept macro and replace with BOOST_NOEXCEPT.
BOOST_NOEXCEPT does what the noexcept macro was supposed to do, but in a
way that is correctly maintained over time.

Alex Miller 244903a9de Spill txsTag by value under TagMsg/ and not TagMsgRef/
There's not a tremendous reason as to why this matters now, but I feel
like I might regret sometime later not keeping the same schema under the
same key.

2019-02-26 18:00:04 -08:00
Alex Miller 2dc57568cb Change many things about log_version.
* log_version in the database (`/conf/log_version`) is now a hint that gets
  rounded to the nearest supported version.
* fdbcli and FDB enforce that only a valid log_version can be configured to
* TLogVersion is persisted in CoreTLogSet (and LogSet and TLogSet)
* Some comments here and there
* Add an assert on filename length to make sure KV-pairs in filename
  don't exceed a maximum length.

Evan Tschannen 3247d59498 partially restored an optimization on remote storage servers where a behind storage server will keep less data in memory.

Jingyu Zhou 7897616164 Fix wait failure bug on cluster controller
The setDistributor() sets an AsyncVar and then runs waitFailureClient. This
ordering is wrong because the AsyncVar::set triggers the other loop to run
first, which will wait on Never(). The correct code should wait on the Future
returned by the waitFailureClient.
