# PyLink 0.9-beta1
Tagged as **0.9-beta1** by [GLolol](https://github.com/GLolol)

### *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.

### 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
- protocols/nefarious: fix wrong variable in "/join 0" handling causing crashes
- 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()`

# [PyLink 0.6.1-dev](https://github.com/GLolol/PyLink/releases/tag/0.6.1-dev)
Tagged as **0.6.1-dev** by [GLolol](https://github.com/GLolol) on 2016-03-02T05:15:22Z

* Bug fix release.
    - unreal: fix handing of users connecting via IPv4 3c3ae10
    - ts6: fix incorrect recording of null IPs as 0 instead of 0.0.0.0 fdad7c9
    - inspircd, ts6: don't crash when receiving an unrecognized UID 341c208
    - inspircd: format kill reasons like `Killed (sourcenick (reason))` properly.

# [PyLink 0.6.0-dev](https://github.com/GLolol/PyLink/releases/tag/0.6.0-dev)
Tagged as **0.6.0-dev** by [GLolol](https://github.com/GLolol) on 2016-01-23T18:24:10Z

Notable changes in this release:

- New "opercmds" plugin:
    - This merges some functionality from the bots plugin, but also adds new commands such as `jupe`, `kill`, `topic`, and `checkban`.
- New "changehost" plugin - Automated configurable vHost setting on connect.
- Some core changes will **break** protocol modules and plugins written for older PyLink versions:
    - Some functions have been renamed:
        - `utils.nickToUid(irc, nick)` -> `irc.nickToUid(nick)`
        - `utils.isInternalClient(irc, uid)` -> `irc.isInternalClient(uid)`
        - `utils.isInternalServer(irc, uid)` -> `irc.isInternalServer(uid)`
        - `utils.clientToServer(irc, uid)` -> `utils.getServer(uid)`
        - `utils.getProtoModule(...)` -> `utils.getProtocolModule(...)`
    - Protocol specification is rewritten, with "Client" and "Server" dropped from the suffix of most outgoing commands: see acdd7dbb782765f581...2fd0a8ae741a663d.
- exec plugin: add `inject` and `raw` commands (4e7396b).
- exec plugin: support newline (and other) escapes in `exec` (375dbe8).
- protocols: allow changing remote users' hosts in updateClient (741fed9).
- Speed up and clean up shutdown sequence, fixing hangs due to sockets not shutting down cleanly (#152).
- protocols/unreal: Support cloaking with user mode `+x` (#136).
- Various bug fixes - see https://github.com/GLolol/PyLink/compare/0.5-dev...0.6.0-dev for a full diff.

# [PyLink 0.5-dev](https://github.com/GLolol/PyLink/releases/tag/0.5-dev)
Tagged as **0.5-dev** by [GLolol](https://github.com/GLolol) on 2015-12-06T17:54:02Z

The "We're getting somewhere..." release.

### Changes
- *Bug fixes, all the bug fixes*.

#### Core
- Support IPv6 connections in config.
- The offending hook data is now logged whenever a hook function errors, for more convenient debugging.
- Add sanity checks for autoconnect - delay has to be at least 1 second now, to prevent connect floods that go on without any delay in between!
- Add `irc.reply()` to send command replies to callers in the right context (channel or PM).
- More base commands are in `coreplugin` instead of `commands.py` now, making the latter reloadable without restart.
- Don't crash when REHASH loads a config file that's invalid.
- utils: Replace imp (deprecated) with importlib.

#### Plugins
- commands: Add a command to set log level (#124).
- commands: Update `irc.botdata` (`bot:` data in config) in REHASH.
- fantasy: Support nick prefixes (e.g. `PyLink: help`), along with a configurable prefix.

#### Protocols
- protocols/TS6: Fix SQUIT handling and introduction of SID-less servers (i.e. atheme's `/os JUPE`) (#119)
- protocols/unreal: **Add (experimental) support for UnrealIRCd 4.0.x!**
- plugins: More complete INFO logging: plugin loading/unloading, unknown commands called, successful operups

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)
- ts6: fix `JOIN` handling and `parse_as` key handling in hooks (ddefd38)

# [PyLink 0.2.0-dev](https://github.com/GLolol/PyLink/releases/tag/0.2.0-dev)
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).
- inspircd: remove `RSQUIT` command handler (3494d4f).

And of course, many, many bug fixes! (relay should now work properly with more than 2 networks, for example...)

### Bug fixes and improvements from 0.1.5-dev

- Irc.send: catch `AttributeError` when `self.socket` doesn't exist; i.e. when initial connection fails (b627513)
- Log output to `log/pylink.log`, along with console (#52, 61804b1 fbc2fbf)
- main/coreplugin: use `log.exception()` instead of `traceback.print_exc()`, so logs aren't only printed to screen (536366d)
- relay: don't relay messages sent to the PyLink client (688675d)
- relay: add a `save` command, and make rescheduling optional in `exportDB()` (c00da49)
- utils: add `getHostmask()` (1b09a00)
- various: Log command usage, `exec` usage, successful logins, and access denied errors in `admin.py`'s commands (57e9bf6)

# [PyLink 0.1.5-dev](https://github.com/GLolol/PyLink/releases/tag/0.1.5-dev)
Tagged as **0.1.5-dev** by [GLolol](https://github.com/GLolol) on 2015-07-18T20:01:39Z

### New features

- Hooks for `CHGHOST`, `CHGIDENT`, and `CHGNAME` (f9d8215 35f1c88)
- IrcUser: Implement user channel tracking via an `IrcUser.channels` attribute (d97fce8)
- Send PING to our uplink periodically, and quit if we don't get a response (#42, #57)
    - New server `pingfreq` option is introduced to set the time between PINGs.
- relay: Only spawn clients if they share a channel, and quit them when they leave all shared channels (cf32461)
- Support autoreconnecting to networks! A new `autoconnect` server setting is added to set autoconnect delay. 
- New `PYLINK_DISCONNECT` hook to keep track of network disconnections (3f6f78b)
- relay: add a `LINKED` command (#65, bbcd70b)
- commands: add a `HELP` command (#8, 6508cb3 4553eda)

### Bug fixes
- relay: don't spawn tagged clones for the internal PyLink client (40fd9e3)
- relay: don't send empty `MODE` commands if there are no supported modes left after filtering (2a586a6)
- protocol/inspircd: don't raise KeyError when removing channel from user fails (73c625a)
- relay: only join PyLink to channels & set topics if there's actually a relay on the network (49943a7)
- relay: fix the wrong modes being propagated to the wrong channels on `LINK` (#53, ccf7596)
- relay: fix "RuntimeError: dictionary changed size during iteration" in `handle_part` (d30890c)
- relay: Only allow messaging users in common channels / channels that you're in (#62, 024ac16)

### Misc. changes
- Move client/server spawning, hook calling, command handling, and KILL/KICK detection outside the protocol module (0aa2f98 fdea348)
- Fix fakeirc and tests for relay (#56, a51cfcb)

### Removed features
- commands: remove `debug` command; it's useless now that `exec`, `showchan`, and `showuser` exist (50665ec)
- admin: `tell` command has been removed. Rationale: limited usefulness; doesn't wrap long messages properly. (4553eda)
