- Clientbot: Fixed nick collisions between virtual clients and real users (#327)
- Fix typo in example conf that caused `log::filerotation` to become an empty, `None`-valued block. This in turn caused the `log` module to crash.
#### Feature changes
- Clientbot now uses a more specific realname fallback ("PyLink Relay Mirror Client") instead of potentially misleading text such as "PyLink Service Client". In the future, this text may be made configurable.
#### Internal fixes / improvements
- setup.py: reworded warnings if `git describe --tags` fails / fallback version is used. Also, the internal VCS version for non-Git builds is now `-nogit` instead of `-dirty`.
- Clientbot now relays text sent from service bots.
- Fixed KeyErrors in Clientbot when receiving WHO replies for clients we don't know -- these are now ignored.
- Relay now skips mode type definitions when doing reverse mode lookup. This fixes channel mode `+l` mever being relayed UnrealIRCd, because `+l` happened to be the only supported type C mode.
- protocols/nefarious: fix UnboundLocalError when no modes are given on user introduction
- fantasy: don't error when bots are removed while processing a message (e.g. on shutdown)
#### Feature changes
- Automode now limits `listacc` to opers instead of all users (with default permissions settings).
The "Badgers" release. Note: This is an **beta** build and may not be completely stable!
### Changes from 0.10-alpha1
#### Bug fixes
- Fixes for the Clientbot protocol module:
- Fix `nick()` referring to the wrong variables (and thus not working at all)
- Fix crashes caused by forced nick changes on connect
- Clientbot now only sends `CHGHOST/CHGIDENT/CHGNAME` hooks the field has actually changed
- Automode now joins the Modebot client on `setacc`, if not already present
#### Feature changes
- Irc: implement basic message queueing (1 message sent per X seconds, where X defaults to 0.01 for servers) .
- This appears to also workaround sporadic SSL errors causing disconnects (https://github.com/GLolol/PyLink/issues/246)
- relay: CLAIM is now more resistant to things like `/OJOIN` abuse<sup><sup><sup>Seriously people, show some respect for your linked networks ;)</sup></sup></sup>.
- core: New permissions system, used exclusively by Automode at this time. See `example-permissions.yml` in the Git tree for configuration options.
- relay_clientbot now optionally supports PMs with users linked via Clientbot. This can be enabled via the `relay::allow_clientbot_pms` option, and provides the following behaviour:
- Private messages and notices *TO* Clientbot users are forwarded from the Relay bot as NOTICE.
- Private messages can be sent *FROM* Clientbot users using the `rpm` command in `relay_clientbot`
- The PyLink launcher now shows the full VCS version in `pylink -v`
- Revert "relay_clientbot: always lowercase network name (stylistic choice)"
#### Internal fixes / improvements
- protocols/unreal: use umode `+xt` instead of blind `/SETHOST` when spawning users
- protocols/clientbot: handle numerics 463 (ERR_NOPERMFORHOST), 464 (ERR_PASSWDMISMATCH), and 465 (ERR_YOUREBANNEDCREEP) as fatal errors
- protocols: various fields in hook payloads are renamed for consistency:
- The `chandata` field in SQUIT payloads is renamed to `channeldata`
- The `oldchan` field in MODE payloads is renamed to `channeldata`
-`Irc.msg()` should no longer send empty text strings (which are technically illegal) in things like help strings.
- Irc: make sending of loopback hooks in `msg()` optional
- relay_clientbot: switch to `irc.msg()` for relayed text
#### Misc. changes
- Various to documentation update and installation instruction improvements.
Tagged as **0.10-alpha1** by [GLolol](https://github.com/GLolol) on 2016-08-22T00:04:34Z
The "Balloons" release. Note: This is an **alpha** build and may not be completely stable! This version includes all fixes from PyLink 0.9.2, with the following additions:
### Changes from 0.9.2
#### Bug fixes
- Improved syncing between Automode and Relay on JOINs. In other words: fixed Automode sometimes setting modes on join before all of a target's relay clones have joined corresponding relay channels on remote networks.
- protocols/inspircd now tracks required modules for vHost updating (CHGHOST/IDENT/NAME), instead of potentially sending unknown commands to the IRCd and causing a netsplit.
- changehost now explicitly forbids `$host` from being used in expansion fields, preventing vHosts from potentially being set in a loop whenever `applyhosts` is called.
-`eval` now formats empty strings correctly, instead of having no visible reply. In other words, it now wraps all output with `repr()`.
- relay: fix reversed prefix mode order in bursts (e.g. `+@~UID` instead of `~@+UID`). Fortunately, this is minor detail; no noticeable adverse effects to IRCd linking was ever experienced.
#### Feature changes
- **WIP** Clientbot protocol module: allows PyLink to connect as a bot to servers, for purposes such as relay.
- Some features such as flood protection, services account tracking, and IRCv3 support are still missing.
- **For Clientbot relay support, remember to also load the `relay_clientbot` plugin!**
- Added the ability to rotate logs at certain sizes, keeping X backups for reference.
- REHASH now updates file logging settings.
- Relay now allows configuring a list of nick globs to always tag nicks (`forcetag_nicks:` block in `relay:`)
- networks: new `reloadproto` command, allowing in-place reloading of protocol modules without restart.
- Ctrl-C / KeyboardInterrupt now cleanly shuts down PyLink (in most cases).
- SSL cert file and key file are now optional.
- changehost: show more friendly errors when an expansion field is unavailable
- protocols/inspircd: add support for SAKICK, ALLTIME.
- protocols/ unreal: add support for TSCTL ALLTIME.
- Added support for `/time` requests.
#### Internal fixes / improvements
- Shutdown now cleanly quits the PyLink service bot instead of simply splitting off.
- PyLink now shows a better error if a protocol module chosen is missing.
- Config key validation is now protocol-specific.
- The `IrcUser.identified` attribute was renamed to `IrcUser.account`.
- exec: make `pylinkirc` and `importlib` accessible for easier debugging.
- SQUIT hooks get a few more arguments, such as `nicks` (affected nicks) and `serverdata` (old IrcServer object).
- Retrieving the hostname used by the current PyLink instance is now a shared function: `irc.hostname()`
- Better handling of empty lines in command help - these are now sent as a single space instead of passing invalid text like `:<UID> NOTICE <UID> :` to the IRCd (no text in the text parameter).
- protocols/ts6: handle incoming ETB (extended topic burst) and EOPMOD (partial support; op moderated +z messages are converted to forms like `@#channel`).
- protocols/unreal: explicitly declare support for ESVID, or account name arguments in service stamps. Realistically this doesn't seem to affect S2S traffic, but it is the correct thing to do.
#### Misc. changes
-`FakeIRC` and `FakeProto` are removed (unused and not updated for 0.10 internal APIs)
- Relay now treats `{}` as valid characters in nicks.
- Fixed services login tracking for older Anope services + UnrealIRCd. Previously, PyLink would incorrectly store login timestamps as the account name, instead of the user's nick.
- Relay now normalizes `/` to `.` in hostnames on IRCd-Hybrid.
- Cloaked hosts for UnrealIRCd 3.2 users are now applied instead of the real host being visible.
### *Important*, backwards incompatible changes for those upgrading from 0.8.x!
- The configuration file is now **pylink.yml** by default, instead of **config.yml**.
- PyLink now requires installing itself as a module, instead of simply running from source. Do this via `python3 setup.py install --user`.
- The `use_experimental_whois` option for InspIRCd servers and the `spawn_servers` option in Relay have been removed, as they are now implied.
### Changes from 0.9.0
#### Bug fixes
- Fixed various bugs in channel TS handling (this should reduce mode desyncs with relay).
- protocols/unreal: fixed services account support for older services (e.g. Anope <2.0)thatdon'texplicitlyuseaccountnamesforlogins(#296).
- Mode changes are no longer sorted alphabetically when relayed: sorting now only applies for displaying a list of modes, such as in WHOIS.
- Invalid autojoin channels are now ignored, instead of passing potentially invalid data to the IRCd.
#### Feature changes
-`setup.py` now explicitly forbids installing on Python 2 (#297).
- The `nefarious` protocol module now forwards MODE and KICK through servers if the sender isn't opped, preventing many mode bounces, kick failures, and HACK server notices.
#### Internal fixes / improvements
- protocols/hybrid,ts6,unreal: Casemapping-specific lowercasing is now consistently used for channel names
- Relay now catches errors on network removal and ignores them.
- Channels names are now case normalized when receiving `@#channel` messages.
### *Important*, backwards incompatible changes for those upgrading from 0.8.x
- The configuration file is now **pylink.yml** by default, instead of **config.yml**.
- PyLink now requires installing itself as a module, instead of simply running from source. Do this via `python3 setup.py install --user`.
----
### Changes from 0.9-alpha1
##### Added / changed / removed features
- The `use_experimental_whois` option for InspIRCd servers is removed, and is now implied.
- New config option `bot: whois_show_extensions_to_bots`, which optionally disables extended WHOIS replies for users marked as a bot (+B).
- This increases security when relay is enabled, for bots that look for services logins in WHOIS.
- Automode has new `clearacc` and `syncacc` commands, for clearing and syncing access lists respectively.
- Relay now allows nick tagging to be turned off by default, via the option `relay: tag_nicks` (#116)
- This is experimental, and nick tagging is still enabled by default.
- Any attempts to KILL or SVSNICK a relay client are treated to force tag a nick, so things like `/ns release`, `/ns ghost`, and `/ns regain` should work with network services.
- Automode now only sends one MODE command per sync, to prevent changes from flooding channels.
- Relay separators can now be configured globally (`relay: separator` option), with server-specific overriding that value if given.
##### Bug fixes
- corecommands: fix `unload` failing to remove hooks and commands (0.9.x regression).
- protocols/nefarious: only send EOB_ACK to the direct uplink, preventing stray "acknowledged end of net.burst" messages from showing up. Thanks to Speakz on Evilnet IRC for reporting.
- protocols/unreal: fix server name of the uplink server not being saved (#268)
- Channel prefixes are now sorted in WHOIS output (i.e. no more wrong `@~#channel`), and only the highest prefix shown
- Fixed issues in internal channel mode tracking (c1cd6f4 58d71b0)
- WHOIS requests to the PyLink server for clients that aren't PyLink bots now work (syntax: `/raw whois pylink.server somenick`). "No such nick" errors are also sent when the target is missing, instead of raising warnings.
- These WHOIS responses were previously sent from the wrong source (the server that the client was on, instead of the PyLink server), causing them to be ignored if they were going the wrong way.
- Automode now treat channels case insensitively in `delacc`.
-`ascii` and `rfc1459` case mappings now treat Unicode case sensitively, in the same way an IRCd would.
##### Internal improvements
- Removed inaccurate references to signon time in WHOIS and elsewhere.
- Changes to user timestamps are now tracked on NICK and SAVE commands
- Relay now creates relay clones with the current time as nick TS, instead of the origin user's TS.
- This has the effect of purposely losing nick collisions against local users, so that it's easier to reclaim nicks.
Tagged as **0.9-alpha1** by [GLolol](https://github.com/GLolol) on 2016-07-09T07:27:47Z
### Summary of changes from 0.8.x
##### Backwards incompatible changes
- Configuration file is now **pylink.yml** by default, instead of **config.yml**.
- PyLink now requires installing itself as a module, instead of simply running from source. Do this via `python3 setup.py install --user`.
##### Added / changed / removed features
- New **`ctcp`** plugin, handling CTCP VERSION and PING ~~(and perhaps an easter egg?!)~~
- New **`automode`** plugin, implementing basic channel ACL by assigning prefix modes like `+o` to hostmasks and exttargets.
- New exttarget support: see https://github.com/GLolol/PyLink/blob/0.9-alpha1/coremods/exttargets.py#L15 for a list of supported ones.
- Relay can now handle messages sent by users not in a target channel (e.g. for channels marked `-n`)
- Relay subserver spawning is now always on - the `spawn_servers` option is removed
- Relay can now optionally show netsplits from remote networks, using a `show_netsplits` option in the `relay:` block
- The `channels` configuration option in `server:` blocks is now optional, and defaults to no channels if not specified
- The `maxnicklen` configuration option is also now optional, with a default value of 30 characters.
-`--version`, `--no-pid`, and `--help` are now implemented by PyLink's command line script
- Test cases were dropped - they were broken and poorly maintained.
- CPUlimit wrapper scripts were removed.
- Service bots now allow plugins to define service descriptions and mark commands as featured when adding them.
- Command replies for services bots are now consolidated into core. In general, FANTASY commands now reply in channel as PRIVMSG, while all commands sent in PM reply as private notices.
- protocols/inspircd: new `use_experimental_whois` server option, which forces PyLink to handle WHOIS requests locally. This allows relay WHOIS extensions like account name and origin server name (`whois_show_*` options) to actually work on InspIRCd networks.
- PyLink can now optionally protect its services clients by setting servprotect modes (InspIRCd umode `+k`, `+S` elsewhere). The option for this is `protect_services` in the `bot:` block.
- The `networks` now deletes IRC objects when `disconnect` is used. To reconnect all disconnected networks, use the `rehash` command.
- Relay now hides disconnected leaf networks from LINKED output.
##### Bug fixes
- Services bots will now ignore unhandled CTCP requests, instead of responding with "Unknown command"
- The `sid` field for TS6 servers now accepts unquoted numeric SIDs (integers) by normalize the SID to a string
- The PyLink bot now rejoins relay channels when it is killed
- protocols/ts6: fix wrong args in TB handling
##### Internal improvements
-`coreplugin.py` is split into `coremods/`, with many different submodules for easier maintenance.
- Rewritten channel TS handling to be more concise and reusable
- protocols/unreal: warn about mode bounces instead of fighting with the uplink
- protocols/ts6, protocols/nefarious: use protocol-specific ban bursting instead of sending a regular MODE
-`Irc.parseModes()` now handles strings given as the mode list properly, instead of only accepting a list of modestring arguments
-`SQUIT` handlers now return an `uplink` field with the SID of the server that the target was split from
- protocols/ts6: send 12 users (SJOIN) and 10 modes (TMODE) per line, instead of 10 and 9 respectively
- Relay is now slightly more careful when normalizing nicks: they can't have invalid characters, start with a hyphen (-), etc.
- Modes are now sorted when joined. You'll now see things like `+Hiow` instead of `+wHoi`
- protocols/inspircd: services clients with mode +k now have the "Network Service" oper type, in WHOIS replies and elsewhere
- SQUIT and KILL handling are moved into a protocols/ircs2s.py module, as the handling is basically the same on both TS6 and P10.
- protocols/nefarious,ts6,unreal: KILL handling (inbound & outbound) now supports kill paths and formats kill reasons properly
- protocols: encapsulated (ENCAP) commands are now implicitly expanded, so protocol modules no longer need to bother with IF statement chains in a `handle_encap()`

Tagged as **0.2.3-dev** by [GLolol](https://github.com/GLolol) on 2015-07-26T06:11:20Z
The "prevent PyLink from wrecking my server's CPU" release.
Mostly bug fixes here, with a couple of scripts added (`start-cpulimit.sh` and `kill.sh`) added to assist running PyLink under the protection of [CPUlimit](https://github.com/opsengine/cpulimit). :)
#### New features
- relay: Block most duplicate modes from being relayed (#71)
- main: write a PID file to `pylink.pid` (f85fbd934bb2001122079da9e37e2fd1f9041a18)
- ts6: support `+AOS` charybdis extension modes, warning if the IRCd doesn't support them (146ab5e)
#### Fixes
- relay: quit users who aren't on any shared channels after KICK (71a3464)
- Use RFC1459 for case mapping on InspIRCd (01220b3)
- relay: Fix handling of local `SAVE` (e4da670) and `KILL` (a4da9b5) commands
- relay: fix nick collision loop on `SAVE` + when both tagged (i.e. _42XAAAAAA) and untagged (42XAAAAAA) versions of a UID nick exist (e354ada)
- relay: Fix command arguments of `DELINK` on home networks (c07cfb1)
- relay: `SJOIN` users once, and only once (#71, b681a67)
- main.Irc: catch `OSError` (bad file descriptor) errors and disconnect
- ts6: add QS as a required capability (69e16e5)

Tagged as **0.2.0-dev** by [GLolol](https://github.com/GLolol) on 2015-07-23T04:44:17Z
Many changes in this development release, including:
- **New `ts6` protocol module, for charybdis 3.x.**
- relay: add nick collision handling via `SAVE` (#61).
- relay: trivial tasks like `TOPIC`, `MODE`, `KICK` and `PART` no longer spawn new clients for their senders, and are routed through the pseudoserver when applicable instead (e76d31d c0f8259).
- Irc: be safer against `UnicodeDecodeError` caused by `socket.recv()` cutoff, by decoding each individual line instead (06d17d5).
- relay: make the `nick/net` separator a per-network config option. (ad34f6c).
- relay: Use a whitelist when it comes to relaying modes (#54), and strip out bans that don't match `nick!user@host` syntax (#55).
- relay: Handle user mode changes (#64).
- Support different case mappings for nicknames (RFC1459 vs ASCII) (#75).
