Description

vere-v3.1 is a a minor runtime release with the following highlighted features:

• Rebinding eyre HTTP cache entires.
• The runtime now automatically tries to open the Ames port on a home network using the NAT-PMP protocol. This will improve connectivity on self-hosted setups.
• Restore the ctrl+z functionality to instantly force kill the urbit process.
• Plug memory leaks related to DNS queries. This has resulted in significant uptime improvements for select Urbit Foundation infrastructure ships.
• More reliable lockfile and replay error handling.
• Miscellaneous error message improvements.

Description

During pre-release testing of vere-v3.1-rc3 we discovered that replaying in a subprocess introduced a failure case in Native Planet lockfile handling heuristics.

Vere lockfile handling is meant to prevent multiple vere processes from starting the same pier at the same time. Unfortunately this lockfile handling has historically been poor and sometimes the lockfile sticks around after a vere process exits abnormally. Native Planet was using PID heuristics to delete these lingering lockfiles, but this method was broken after #654.

This release candidate contains #697 that uses advisory locking syscalls to significantly improve lockfile reliability. The fix has also been tested to work across the Docker host -> container barrier.

What's Changed

• docs: add autoconf-archive to installation instructions by @matthew-levan in #692
• vere: use fcntl advisory locks on pidfile by @joemfb in #697

Description

During pre-release testing of vere-v3.1-rc2 it was discovered that informal pinging was broken. This remained undetected because informal pinging falls back to formal pinging when malfunctioning. This release candidate includes #694 to fix the issue.

What's Changed

• stun: fix stun by @pkova in #694

Description

During pre-release testing of vere-v3.1-rc1 we discovered that a PR for improving error messages when the disk is full was mistakenly not included. This release candidate includes #636 with the improved error messages.

Full Changelog: vere-v3.0...vere-v3.1

Description

The big ticket items for this vere release include the epoch system, support for persistent nock caching, informal pings and MDNS local routing. The epoch system is functional immediately after upgrading to vere-v3.0, the other features are reliant on the 411k release slated for ~2024.3.18.

This release is not backwards compatible with vere-v2.12 and earlier. A ship cannot be downgraded after upgrading to vere-v3.0.

Epoch System

The epoch system cuts the previously uniform event log into "epochs" associated with a specific runtime version. The epochs are represented as directories in the file system. Here is an example of epochs under the Foundation galaxy ~deg that has been running the vere-v3.0 pre-release for a while:

ls ./deg/.urb/log/
0i0  0i95419173  0i98550959  0i99182407  0i99543593  data.mdb  lock.mdb

Each epoch folder is identified by an event number and includes a snapshot and a part of the event log. If the snapshot of a ship gets corrupted the ship may have to replay; the epoch system makes this process more pleasant since the ship no longer has to replay the entire event log. A replay can be initiated from the latest valid epoch, significantly speeding up the process.

The latest snapshot for a ship is situated in the latest epoch, 0i99543593 in the above case. All other epochs are safe to relocate elsewhere or even delete.

The default behavior for the epoch system is to create a new epoch every time the vere runtime version changes. A user may also manually create a new epoch by using the urbit roll command.

The urbit chop command now deletes all epochs except for the last two.

Description

During pre-release testing of vere-v3.0-rc4 the ship ~dinleb-rambep experienced loom corruption caused by the refcount of a jet registration noun being off by one. We were unable to reproduce the issue but decided to revert #538 out of an abundance of caution. We also added the --gc-early subcommand to recover the potentially existing ships that had been running release candidate with the issue.

What's Changed

• Revert "u3: restore old-style, efficient reap to u3m_love()" by @pkova in #612
• vere: adds --gc-early flag to pack and meld subcommands by @pkova in #615

Full Changelog: vere-v3.0-rc4...vere-v3.0-rc5

Description

During pre-release testing of vere-v3.0-rc3 a bug was discovered with the free list migration. This bug caused spurious "loom: corrupt" warnings for some ships when upgrading from vere-v2.12 to vere-v3.0. Another bug was discovered in error handling of the urbit chop command, causing problems if the ship crashed exactly during a chop.

This release candidate includes #602 and #608 to fix these bugs.

What's Changed

• vere: fix epoc lifecycle error handling, enforce invariants by @joemfb in #602
• http: do not double free scry cache path by @pkova in #606
• v3-migrate: ream before reclaiming bytecode caches by @pkova in #608

Full Changelog: vere-v3.0-rc3...vere-v3.0-rc4

Description

During pre-release testing of vere-v3.0-rc2 a bug was discovered with LMBD initialization where if your ship does not fit in a direct atom certain migration scenarios could crash. We also noticed a regression in the chop command. This release candidate fixes those issues in addition to some typos in ames czar printfs.

What's Changed

• ames: fix ames czar prints by @yosoyubik in #595
• epoc: fix log metadata write bug, make pre-release repair more robust by @joemfb in #596
• vere: fix chop by @joemfb in #599

Full Changelog: vere-v3.0-rc2...vere-v3.0-rc3

Description

During pre-release testing of vere-v3.0-rc1 a bug was discovered in situations where a ship would crash exactly when performing the migration to the epoch system. This scenario together with an attempt to downgrade back to vere-v2.12 would result in the pier being left in a broken state. #592 fixes this problem.

This release candidate also includes a fix for MDNS to distinguish between fake ships and real ships on the local network.

What's Changed

• mdns: distinguish fake ships in the mdns namespace by @pkova in #584
• bazel: bump zlib by @pkova in #590
• fix epoch migration bug by @matthew-levan in #592
