Alphanet changelog

|
==================
|
|
|
|
For the next reset
|
|
------------------
|
|
|
|
[Alpha]
|
|
|
|
- Do not allow revealing the same endorsement twice.
|
|
|
|
- Tez values now have 6 decimals instead of two. The syntax used by
|
|
the client and Michelson use comma separators every three
|
|
digits, before and after the dot. For instance, 3 million tez and 10
|
|
µtez is written `3,000,000.000,01`. The syntax in JSON is the raw
|
|
amount in µtez, either as a number without decimals or as a decimal
|
|
string, for the same example we would get `"3000000000010"`.
|
|
|
|
[Node]
|
|
|
|
- Rewrite of the RPC library to handle content types, to enable binary
|
|
RPCs and proper HTTP verbs. The next version will probably break the
|
|
HTTP API.
|
|
|
|
- Now that we don't use the git backend anymore, we finally updated
|
|
the context hashing function from SHA1 to Blake2B.
|
|
|
|
[Michelson]
|
|
|
|
- Set a maximum type size, as a simple solution to avoid some type
|
|
checker abuses where types can grow exponentially.
|
|
|
|
- Annotations are now correctly handled by macros.
|
|
|
|
[Build]
|
|
|
|
- Split the code base into separate OPAM packages.
|
|
|
|

Reset 2017-11-20
|
|
------------------
|
|
|
|
[Alphanet]
|
|
|
|
- Limit the number of faucet operations at 5 per block.
|
|
|
|
[Client]
|
|
|
|
- Autocomplete scripts for bash.
|
|
|
|
- Smart contracts are now non spendable by default.
|
|
|
|
- Add a debug command to list invalid blocks.
|
|
|
|
[Node]
|
|
|
|
- Prevent potential stack overflow in validation.
|
|
|
|
- Fix concurrency issue where operations were cleared from
|
|
memory before being used.
|
|
|
|
- Continue background work on the multipass validator:
|
|
cleanup and document data structures, better logging
|
|
of resource requests, enhance requests for the same piece
|
|
of data to multiple peers, split the code in smaller
|
|
simpler components.
|
|
|
|
- P2p: fix issue with data greater than 2^16 bytes
|
|
|
|
- Irmin: use an experimental LevelDB backend
|
|
|
|
[Build]
|
|
|
|
- Refactor the economic protocol amendment code. Protocols are
|
|
now compiled to functors, taking the type signature of their
|
|
runtime environment as parameter. This simplifies the
|
|
dependencies, and will allow third party developers to
|
|
instanciate economic protocols in other contexts than the node.
|
|
|
|
- Switch from Makefiles to jbuilder, yay!
|
|
|
|
- Rename (hopefully) all occurences of "mining" into "baking".
|
|
|
|
[Michelson]
|
|
|
|
- Introduce Micheline, the (now independent) IR of Michelson.
|
|
The parser and printer should now be used on their own, outside
|
|
of the client or node.
|
|
|
|
- Implement a basic semantics of annotations.
|
|
The typechecker now propagates annotations on types througout the
|
|
code, and tagging instructions with an annotation allows the
|
|
programmer to reannotate the element produced by the instruction.
|
|
The emacs mode displays propagated annotations.
|
|
|
|
- Add a version of `ITER` that takes a static code block and expects
|
|
a colletion on the initial stack, and works like a `LOOP`, pushing
|
|
the element of the collection one at a time on the stack. This is
|
|
like `REDUCE` but using a static code block instead of a dynamic
|
|
lambda. In the same vein, `MAP` can take a code block.
|
|
|
|
- Add `LOOP_LEFT` that uses a different type for the accumulator and
|
|
the return value. Continues while the top of the stack is `Left 'a`
|
|
and stops on `Right 'b`.
|
|
|
|
- Change timestamps to be arbitrary precision relative integers.
|
|
|
|
- Add `SIZE` on lists.

Reset 2017-08-10
|
|
----------------
|
|
|
|
This update includes changes in the on-disk state of the node and in
|
|
the format of blocks and operations. It thus requires a chain reset.
|
|
|
|
Main changes includes:
|
|
|
|
[Doc]
|
|
|
|
- The documentation previously available on the Slack channel is now
|
|
available at:
|
|
|
|
https://raw.githubusercontent.com/tezos/tezos/alphanet/README.md
|
|
|
|
- The `alphanet` branch of the github repository is now automaticaly
|
|
synchronized with `alphanet` docker image. And the latest version of
|
|
the `alphanet.sh` is available at:
|
|
|
|
https://raw.githubusercontent.com/tezos/tezos/alphanet/scripts/alphanet.sh
|
|
|
|
No need to update manually though, the script auto-update itself
|
|
when running:
|
|
|
|
./alphanet.sh restart
|
|
|
|
Or:
|
|
|
|
./alphanet.sh update_script
|
|
|
|
|
|
[Michelson]
|
|
|
|
- minor language enhancements, mostly resulting from the feedback of
|
|
Milo's daily challenge:
|
|
|
|
http://www.michelson-lang.com/
|
|
|
|
- the alphanet scripts now understands a container: prefix wherever a
|
|
file: prefix is accepted, temporarily copying the file into the
|
|
container, and the emacs-mode is aware of that
|
|
|
|
[Node]
|
|
|
|
- Operations now include a block hash in their header. Such an
|
|
operation could only be included in a successor of this block.
|
|
|
|
- The economics protocol now refuses blocks that includes an operation
|
|
forged more than 64 blocks in the past. As any constants set by the
|
|
economic protocol, it is amendable by a vote.
|
|
|
|
- Header of blocks now includes a hash of the "context" that result
|
|
from its validation. This is currently the SHA1 of the git commit,
|
|
but this will be changed in a near future for a safer cryptographic
|
|
hash.
|
|
|
|
- The node does not need anymore to maintain a full index of the
|
|
operation to operate. This greatly reduce the memory and disk usage.
|
|
|
|
- The node now builds against `irmin.1.3` where some of our code and
|
|
optimizations were upstreamed. We were previously stuck to
|
|
irmin.0.12.
|
|
|
|
|
|
[CI]
|
|
|
|
- This is not directly visible in the alphanet, but our CI
|
|
infrastrucre is now ready for open development.
|
|
More about that soon (or later).
