For the next reset
==================
2017-11-20 03:12:58 +04:00
[Alphanet]
- Limit the number of faucet operations at 5 per block.
2017-11-06 19:28:06 +04:00
[Client]
2017-11-20 03:12:58 +04:00
- Autocomplete scripts for bash.
2017-11-06 19:28:06 +04:00
- Smart contracts are now non spendable by default.
[Node]
2017-11-20 03:12:58 +04:00
- Prevent potential stack overflow in validation.
2017-11-06 19:28:06 +04:00
- 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
2017-11-20 03:12:58 +04:00
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
2017-11-06 19:28:06 +04:00
[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 developpers 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 2017-11-17
================
[Node]
- P2p: fix issue with data greater then 2^16 bytes
- Irmin: restore usage `git-repack`... (mistakenly removed)
2017-11-06 19:28:06 +04:00
Reset 2017-10-13
================
[Client]
- Fix missing nonce revelation at end of cycle.
- New command line analyzer and better help pages.
[Node]
- Various small fixes and error message enhancements.
[Alphanet]
- Use older leveldb-1.18 as upgrade to the newer version made the
node crash.
[Michelson]
- Split the `key` type into `key` and `key_hash` to
prevent an error raised when using an unrevealed key.
2017-09-22 00:35:33 +04:00
Reset 2017-09-21
================
[Node]
- fix a performance issue in roll storage
[Doc]
- improve scripts and documentations on how to run sandboxed node
or a local private network
[Client]
- add an option `-log-requests`. All RPC requests and responses to the
node are logged on `stderr`.
2017-11-06 19:28:06 +04:00
[Michelson]
- Split the `key` type into `key` and `key_hash` to
prevent an error raised when using an unrevealed key.
2017-09-22 00:35:33 +04:00
2017-08-10 22:10:08 +04:00
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]
2017-11-06 19:28:06 +04:00
- minor language enhancements, mostly resulting from the feedback of
2017-08-10 22:10:08 +04:00
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
2017-11-06 19:28:06 +04:00
forged more than 64 blocks in the past. As any constants set by the
2017-08-10 22:10:08 +04:00
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).
