Beta 2.5.3 (#10776)
* ethcore/res: activate atlantis classic hf on block 8772000 (#10766)

* fix docker tags for publishing (#10741)

* fix: aura don't add `SystemTime::now()` (#10720)

This commit does the following:
- Prevent overflow in `verify_timestamp()` by not adding `now` to found faulty timestamp
- Use explicit `CheckedSystemTime::checked_add` to prevent potential consensus issues because SystemTime is platform
depedent
- remove `#[cfg(not(time_checked_add))]` conditional compilation

* Update version

Bundle protocol and packet_id together in chain sync (#10315)
Define a new `enum` where devp2p subprotocol packet ids (currently eth and par) are defined. Additionally provide functionality to query id value and protocol of a given id object.

751d15e4be fix(light-rpc): Make light_sync generic (#10238)
* fix(light-rpc): Make `light_sync` generic

The motivation behind this change is to easily mock `light-sync` to make it possible to enable `rpc-integration` tests
for the light-client.

Currently the `rpc's` requires the concrete type `sync::LightSync` which makes it very hard to do so

* Remove "SyncIO::send" and leave only "SyncIO::send_protocol"

* Adapt tests to new code.

a devp2p packet.

Fix pubsub new_blocks notifications to include all blocks (#9987)
Fix: new blocks notifications sometimes missing in pubsub RPC

Implement new struct to pass to `new_blocks()` with extra parameter - `has_more_blocks_to_import`, which was previously used to determine whether the notification should be sent. Now it's up to each implementation to decide what to do.

Updated all implementations to behave as before, except `eth_pubsub`, which will send notification even when the queue is not empty.

Update tests.

4b6ebcbb61 Fix ancient blocks sync (#9531)
* Log block set in block_sync for easier debugging

* logging macros

* Match no args in sync logging macros

* Add QueueFull error

* Only allow importing headers if the first matches requested

* WIP

* Test for chain head gaps and log

* Calc distance even with 2 heads

* Revert previous commits, preparing simple fix

This reverts commit 5f38aa885b22ebb0e3a1d60120cea69f9f322628.

* Reject headers with no gaps when ChainHead

* Reset block sync download when queue full

* Simplify check for subchain heads

* Add comment to explain subchain heads filter

* Fix is_subchain_heads check and comment

* Prevent premature round completion after restart

This is a problem on mainnet where multiple stale peer requests will
force many rounds to complete quickly, forcing the retraction.

* Reset stale old blocks request after queue full

* Revert "Reject headers with no gaps when ChainHead"

This reverts commit 0eb865539e5dee37ab34f168f5fb643300de5ace.

* Add BlockSet to BlockDownloader logging

Currently it is difficult to debug this because there are two instances,
one for OldBlocks and one for NewBlocks. This adds the BlockSet to all
log messages for easy log filtering.

* Reset OldBlocks download from last enqueued

Previously when the ancient block queue was full it would restart the
download from the last imported block, so the ones still in the queue would be
redownloaded. Keeping the existing downloader instance and just
resetting it will start again from the last enqueued block.:wq

* Ignore expired Body and Receipt requests

* Log when ancient block download being restarted

* Only request old blocks from peers with >= difficulty

https://github.com/paritytech/parity-ethereum/pull/9226 might be too
permissive and causing the behaviour of the retraction soon after the
fork block. With this change the peer difficulty has to be greater than
or euqal to our syncing difficulty, so should still fix
https://github.com/paritytech/parity-ethereum/issues/9225

* Some logging and clear stalled blocks head

* Revert "Some logging and clear stalled blocks head"

This reverts commit 757641d9b817ae8b63fec684759b0815af9c4d0e.

* Reset stalled header if useless more than once

* Store useless headers in HashSet

* Add sync target to logging macro

* Don't disable useless peer and fix log macro

* Clear useless headers on reset and comments

* Use custom error for collecting blocks

Previously we resued BlockImportError, however only the Invalid case and
this made little sense with the QueueFull error.

* Remove blank line

* Test for reset sync after consecutive useless headers

* Don't reset after consecutive headers when chain head

* Delete commented out imports

* Return DownloadAction from collect_blocks instead of error

* Don't reset after round complete, was causing test hangs

* Add comment explaining reset after useless

* Replace HashSet with counter for useless headers

* Refactor sync reset on bad block/queue full

* Add missing target for log message

* Fix compiler errors and test after merge

c1aed4af45 Fix light client deadlock (#9385)
This PR is fixing deadlock for #8918 

It avoids some recursive calls on light_sync by making state check optional for Informant.

The current behavior is to display the information when informant checks if block is major version.
This change a bit the informant behavior, but not on most cases.

To remember where and how this kind of deadlock are likely to happen (not seen with Parkinglot deadlock detection because it uses std condvar), I am adding a description of the deadlock.
Also, for the reviewers there may be better solution than modifying the informant.

### Thread1 

- ethcore/sync/light_sync/mod.rs

A call to the light handler through any Io (having a loop of rpc query running on like client makes the dead lock way more likely).
At the end of those calls we systematically call `maintain_sync` method.

Here maintain_sync locks `state` (it is the deadlock cause), with a write purpose

`maintain_sync` -> `begin_search` with the state locked open

`begin_search` -> lightcliennt `flush_queue` method

- ethcore/light/src/client/mod.rs

`flush_queue` -> `flush` on queue (HeaderQueue aka VerificationQueue of headers)

- ethcore/src/verification/queue/mod.rs

Condition there is some unverified or verifying content

`flush` wait on a condvar until the queue is empty. The only way to unlock condvar is that worker is empty and unlock it (so thread 2 is Verification worker).

### Thread2

A verification worker at the end of a verify loop (new block).

- ethcore/src/verification/queue/mod.rs

thread loops on `verify` method.

End of loop condition is_ready -> Import the block immediately 

calls `set_sync` on QueueSignal which send a BlockVerified ClientIoMessage in inner channel (IoChannel of ClientIoMessage) using `send_sync`

- util/io/src/service_mio.rs

IoChannel `send_sync` method calls all handlers with `message` method; one of the handlers is ImportBlocks IoHandler (with a single inner Client service field)

- ethcore/light/src/client/service.rs

`message` trigger inner method `import_verified`

- core/light/src/client/mod.rs

`import_verified` at the very end notify the listeners of a new_headers, one of the listeners is Informant `listener` method

- parity/informant.rs

`newHeaders` run up to call to `is_major_importing` on its target (again clinet)

-  ethcore/sync/src/light_sync/mod.rs

Here `is_major_importing` tries to get state lock (read purpose only) but cannot because of previous state lock, thus deadlock
