Raw Blame History

PyLink 2.0-alpha1

The “Eclectic” release. This release includes all changes from 1.2.1, plus the following:

New features

  • Login blocks can now be limited by network, user hostname, and IRCop status: see the new “require_oper”, “hosts”, and “networks” options in the example config.
  • Added support for ngIRCd, ChatIRCd, and beware-ircd (via protocol modules ngircd, ts6, p10 respectively)
  • Add support for extbans in protocols and relay: this is supported on UnrealIRCd, Charybdis (and derivatives), InspIRCd, and Nefarious P10.
    • Yes, this means you can finally mute bothersome relay users.
  • Clientbot is now more featureful:
    • Added support for IRCv3 caps account-notify, account-tag, away-notify, chghost, extended-join, and userhost-in-names
    • Configurable alternate / fallback nicks are now supported: look for the pylink_altnicks option in the example config.
    • Added support for WHOX, to complement IRCv3 account-notify and account-tag.
    • Relay_clientbot can now relay mode changes as text.
    • Clientbot can now optionally sync ban lists when it joins a channel, allowing Relay modesync to unset bans properly. See the fetch_ban_lists option in the example config.
  • PyLink received a new launcher, which now checks for stale PID files (when psutil is installed) and supports shutdown/restart/rehash via the command line.
  • New commands for the opercmds plugin, including:
    • chghost, chgident, and chgname, for IRCds that don’t expose them as commands.
    • massban, masskill, massbanre, and masskillre - these commands allow setting kickbans, kills, or glines on users matching a PyLink mask (n!u@h mask/exttarget) or regular expression. The hope is that these tools can help opers actively fight botnets as they are connected, similar to atheme’s clearchan and Anope’s chankill commands.
    • checkbanre - a companion to checkban, using regex matching
  • Better support for (pre-defined) U-lined services servers in relay:
    • CLAIM restrictions are relaxed for service bots, which may now join with ops and set simple modes. This prevents mode floods when features such as DEFCON are enabled, and when a channel is accidentally registered on a network not on the CLAIM list.
    • DEFCON modes set by services are ignored by Relay instead of bounced, and do not forward onto other networks unless the setting network is also in the channel’s CLAIM list.
    • To keep the spirit of CLAIM alive, opped services not in a channel’s CLAIM list are still not allowed to kick remote users, set prefix modes (e.g. op) on others, or set list modes such as bans.
  • Service bots’ hostnames and real names are now fully configurable, globally and per network.
  • Added per-network configuration of relay server suffixes.
  • Added IRC /STATS support via the stats plugin (/stats c, u, and o are supported so far)
  • PyLink’s connection time is now displayed when WHOISing service bots. This info can be turned off using the pylink:whois_show_startup_time option.
  • More specific permissions for the remote command, which now allows assigning permissions by target network, service bot, and command.
  • New $service exttarget which matches service bots by name.

Backwards incompatible changes

  • Signal handling on Unix was updated to use SIGUSR1 for rehash and SIGHUP for shutdown - this changes PyLink to be more in line with foreground programs, which generally close with the owning terminal.
  • Some options were deprecated and renamed:
    • The p10_ircd option for P10 servers is now named ircd, though the old option will still be read from.
    • The use_elemental_modes setting on ts6 networks has been deprecated and replaced with an ircd option targeting charybdis, elemental-ircd, or chatircd. Supported values for ircd include charybdis, elemental, and chatircd.
  • PID file checking is now enabled by default, along with checks for stale PID files only when psutil is installed. Users upgrading from PyLink < 1.1-dev without psutil installed will need remove PyLink’s PID files before starting the service.
  • The fml command in the games plugin was removed.

Bug fixes

  • Relay should stop bursting channels multiple times on startup now. (initialize_channel now skips execution if another thread is currently initializing the same channel)
  • Fixed a long standing bug where fantasy responses would relay before a user’s original command if the fantasy plugin was loaded before relay. (Bug #123)

Internal changes

  • API Break: The protocol module layer is completely rewritten, with the Irc and Protocol-derived classes combining into one. Porting will be needed for old protocol modules and plugins targetting 1.x; see the new (WIP) protocol specification for details.
  • API Break: Channels are now stored in two linked dictionaries per IRC object: once in irc._channels, and again in irc.channels. The main difference is that irc._channels implicitly creates new channels when accessing them if they didn’t previously exist (prefer this for protocol modules), while irc.channels does not raises and raises KeyError instead (prefer this for plugins).
  • API Break: Most methods in utils and classes were renamed from camel case to snake case. log, conf, and others will be ported too before the final 2.0 release.
  • API Break: IRC protocol modules’ server introductions must now use post_connect() instead of connect() to prevent name collisions with the base connection handling code.
  • Channels are now stored case insensitively internally, so protocol modules and new plugins no longer need to manually coerse names to lowercase.
  • Plugins can now bind hooks as specific priorities via an optional priority option in utils.add_hook. Hooks with higher priorities will be called first; the default priority value us 500.
  • Commands can now be properly marked as aliases, so that duplicates don’t show in the list command.
  • Added basic GLINE/KLINE support for most IRCds; work is ongoing to polish this off.
  • PyLink accounts are now implicitly matched: i.e. user1 is now equivalent to $pylinkacc:user1
  • Added complete support for “Network Administrator” and “Network Service” as oper types on IRCds using user modes to denote them (e.g. UnrealIRCd, charybdis).
  • User and server hop counts are now tracked properly instead of being hardcoded as 1.
  • protocols/p10 now bursts IPv6 IPs to supported uplinks.
  • Fixed compatibility with ircd-hybrid trunk after commit 981c61e (EX and IE are no longer sent in the capability list)

PyLink 1.2.1

The “Dancer” release. Changes from 1.2.0:

Bug fixes

  • unreal: fix TypeError when relaying prefix modes via mode()
  • Fix wrong database and PID filenames if the config file name includes a period (“.”)
  • automode: don’t send empty mode lines if no users match the ACL
  • networks: check in “remote” that the remote network is actually connected
  • Fix commonly reported crashes on logging: config syntax errors (49136d5)
  • Backported fixes from 2.0-dev:
    • p10: fix wrong hook name for user introduction
    • clientbot: warn when an outgoing message is blocked (e.g. due to bans) (#497)
    • ts6: fix setting real host of users to ‘None’ if it wasn’t given

Misc changes

  • Removed incorrect descriptions regarding P10 extended_accounts. Both X3 and atheme support extended accounts, and this needs to match your IRCd settings regardless.
  • Updated definitions in channel/user-modes.csv.

Internal improvements

  • Backported improvements from 2.0-dev:
    • Fix support for Hybrid 8.x trunk
    • Minor logging cleanup for relay and Irc.matchHost().
    • Fix cmode +p mapping on TS6 networks.

PyLink 1.2.0

The “Dragons” release. Changes since 1.2.0-rc1:

Feature changes

  • Make relay nick tagging configurable per-network; backported from 2.0-dev (#494)

Bug fixes

  • Fix extraneous removal of PID files even when -n/--no-check-pid was set or if the PID file already existed on launch (PyLink would quit and delete the old PID file in these cases)
  • servprotect: bump default threshold up to 10 hits/10 seconds, as the old limit was too prone to false positives
  • Fix extraneous queue threads not being stopped when a network disconnects (0d5afd2)
  • Fix relay errors on disconnect due to race conditions in network handling (a0a295f)

Misc changes

  • Updated example config and FAQ.

For a summary of major changes since 1.1.x, see the changelog for 1.2.0-rc1.

PyLink 1.2.0-rc1

The “Droplet” release. Changes since 1.2-beta1:

Bug fixes

  • relay: fix channel claim disabling (i.e. “CLAIM #channel -” was broken since 1.2-alpha1)
  • IRCS2SProtocol: fix UnboundLocalError in “message coming from wrong way” error
  • ts6: fix parsing of the INVITE command’s ts argument
  • automode: fix formatting and examples in setacc help text
  • p10: fix rejoin-on-kick relaying by also acknowledging kicks sent from PyLink to its clients with a PART

Major changes since 1.1.x

  • Added support for snircd, ircu, and other (generic) P10 variants. The target IRCd can be chosen using the new server-specific p10_ircd option; see the example config for details (#330).
  • The nefarious protocol module was renamed to p10, as it is no longer Nefarious-specific. You should update your configuration to use the new name!
  • Certain configuration options were renamed / deprecated:
    • The bot: configuration block was renamed to pylink:, with the old name now deprecated.
    • logging:stdout is now logging:console (the previous name was a misnomer since text actually went to stderr).
    • The bot:prefix option is deprecated: you should instead define the prefixes setting in a separate config block for each service you wish to customize (e.g. set automode:prefix and games:prefix)
  • Using new-style accounts exclusively (i.e. specifying things under login:accounts) now requires a permissions: block for PyLink to start (#413).
  • New stats (uptime info) and global (global announcement) plugins.
  • Plugins and protocol modules can now be loaded from any directory, using the new plugin_dirs and protocol_dirs options. (#350)
    • The pylink-contribdl utility was dropped as it is now it obsolete.
  • Relay message formatting became more flexible, and messages from servers (e.g. spurious invite announcements) can now be dropped: look for the relay_weird_senders and accept_weird_senders options.
  • Relay now forbids linking to channels where the home network is down, which previously caused errors due to unreliable target TS (#419). This, along with the regular TS check, can be overridden with a new link --force option.
  • The remote command now routes replies back to the caller network, and supports service bots that aren’t the main PyLink bot via a --service option.
  • Service bot spawning can now be disabled via the global spawn_services and per-service spawn_service options; doing so will merge the relevant commands into the main PyLink bot.
  • Added a pylink::show_unknown_commands option to optionally disable “unknown command” errors. This option can also be overridden per-server and per-service (#441).
  • Added a pylink::prefer_private_replies option to default to private command replies (#409).
  • Relay can now announce to leaf channels when the home network disconnects; see the relay::disconnect_announcement option (#421).

For a full list of changes since 1.1.x, consult the changelogs for the 1.2.x beta and alpha releases below.

PyLink 1.2-beta1

The “Dynamo” release. This release includes all fixes from 1.1.2, plus the following:

Feature changes

  • Added configurable encoding support via the encoding option in server config blocks (#467).
  • Certain configuration options were renamed / deprecated:
    • The bot: configuration block was renamed to pylink:, with the old name now deprecated.
    • logging:stdout is now logging:console (the previous name was a misnomer since text actually went to stderr).
    • The bot:prefix option is deprecated: you should instead define the prefixes setting in a separate config block for each service you wish to customize (e.g. set automode:prefix and games:prefix)
  • Added new $and and $network exttargets - see the new exttargets documentation page for how to use them.
  • Hostmasks can now be negated in ban matching: e.g. !*!*@localhost now works. Previously, this negation was limited to exttargets only.
  • relay_clientbot no longer colours network names by default. It is still possible to restore the old behaviour by defining custom clientbot styles.
  • relay_clientbot no longer uses dark blue as a random colour choice, as it is difficult to read on clients with dark backgrounds.

Bug fixes

  • Fix service respawn on KILL not working at all - this was likely broken for a while but never noticed…
  • Fix kick-on-rejoin not working on P10 IRCds when joinmodes is set. (a.k.a. acknowledge incoming KICKs with a PART per the P10 specification)
  • servprotect: only track kills and saves to PyLink clients, not all kills on a network!
  • Fix ~#channel prefix messages not working over relay on RFC1459-casemapping networks (#464).
  • Show errors when trying to use showchan on a secret channel in the same way as actually non-existent channels. Previously this error response forced replies as a private notice, potentially leaking the existence of secret/private channels.
  • example-conf: fix reversed description for the password encryption setting.

Internal changes

  • Portions of the IRC/relay stack were refactored to prevent various hangs on shutdown.
  • Performance improvements for outgoing message queuing: the queue system now blocks when no messages are in the queue instead of polling it multiple times a minute.
  • Logging fixes: startup warnings (e.g. from config deprecations) now log to files as well as the console.

PyLink 1.2-alpha1

The “Darkness” release. This release includes all fixes from 1.1.2, plus the following summary of changes:

Feature changes

  • Added support for snircd, ircu, and other (generic) P10 variants. The target IRCd can be chosen using the new server-specific p10_ircd option; see the example config for details (#330).
  • The nefarious protocol module was renamed to p10 - you should update your configuration to use the new name!
  • Plugins and protocol modules can now be loaded from any directory, making pylink-contrib 20% more useful! Look for the plugin_dirs and protocol_dirs options in the example config. (#350)
    • The pylink-contribdl utility was dropped as this makes it obsolete.
  • Relay now forbids linking to channels where the home network is down, which previously caused errors due to unreliable target TS (#419). This, along with the regular TS check, can be overridden with a new link --force option.
  • SASL timeout for clientbot is now configurable, with the default raised to 15 seconds
  • New-style accounts (i.e. anything under login:accounts) now require a permissions: block for PyLink to start (#413).
  • New stats (uptime info) and global (global announcement) plugins
  • Improvements to the remote command of the networks plugin:
    • Plugin replies are now routed back to the sender’s network.
    • Added an optional --service option to call commands for service bots other than the main PyLink service.
  • servprotect KILL/SAVE limits and expiry time are now configurable (#417)
  • Added the pylink::show_unknown_commands option to optionally disable “unknown command” errors. This option can also be overridden per-server and per-service (#441).
  • Added the pylink::prefer_private_replies option to default to private command replies (#409)
  • Relay message formatting became more flexible, and messages from user-less senders can now be dropped (fa30d3c c03f2d7)
  • Added global and per-service spawn_service(s) options to optionally disable service bot spawning
  • The bots plugin now allows specifying channel prefixes (e.g. @+) in join
  • exec: Added iexec, ieval, peval, pieval: i* commands run code in an isolated, persistent local scope, while p* commands evaluate expressions while pretty-printing the output
  • Relay: implement optional network disconnect announcements (see the relay::disconnect_announcement option; #421)

Bug fixes

  • Service bots no longer throw errors when attempting to call empty commands via fantasy.
  • Protocol modules now send PONG immediately instead of queuing it, which should prevent ping timeouts at times of very high activity.

Internal improvements

  • Protocols now verify that incoming messages originate from the right direction (#405)
  • Irc.matchHost now supports matching CIDR ranges (#411)
  • Added an utils.IRCParser class based off argparse, for flexible argument parsing (#6).
  • Rewrote outgoing message queues to use queue.Queue (#430), and support a limit to the amount of queued lines (#442)
    • Also, added a clearqueue command to force clear the queue on a network.
  • PyLink protocol capabilities were introduced, reducing the amount of protocol name hardcoding in plugins (#337)
  • Service bots no longer create stubs on Clientbot networks, and instead route replies through the main bot (#403)
  • The default throttle time was halved from 0.01s to 0.005s.
  • ServiceBot is now more flexible in help formatting, fixing indented lines and consecutive newlines not showing on IRC.
  • Configuration validation no longer uses skippable asserts (#414)
  • inspircd: better support for OPERTYPE on InspIRCd 3.x
  • Clientbot now tracks channel modes and channel TS on join.
  • Clientbot now generates PUIDs/PSIDs with the nick or server name as prefix, and checks to make sure incoming senders don’t clash with one.
  • commands: showchan now shows TS on connections without the has-ts protocol capability as well, even though this value may be unreliable

Misc changes

  • The bot: config block is renamed to pylink:. Existing configurations will still work, as the bot and pylink blocks are always merged together (#343).
  • Added better documentation for generic options available to all service bots (nick, ident, prefix for fantasy, etc.)
  • Irc.botdata, Irc.conf, Irc.checkAuthenticated() have been deprecated: use conf.conf['pylink'], conf.conf, and the permissions API respectively instead!

PyLink 1.1.2

The “Calamari” release.

Bug fixes

  • Multiple fixes for the unreal protocol module when using UnrealIRCd 3.2 links:
    • fccec3a Fix crashes on processing SJOIN when a user behind a 3.2 server has a nick starting with a symbol
    • 8465edd Fix kicks to Unreal 3.2 users (PUIDs) not updating the internal state - this would’ve caused odd prefix mode desyncs if a user was kicked and rejoined.
    • df4acbf Fix prefix modes not being set on Unreal 3.2 users (affects Automode, etc.)
  • Backported SASL fixes from 1.2-dev:
    • b14ea4f Send CAP LS before NICK/USER so that we consistently get a SASL response before connect - this fixes SASL on networks like freenode, where connections can often complete before a SASL response from services is ever received.
    • 84448e9 22ceb3f The above commit rewrites SASL to depend on a timely response from the server, so a configurable timeout for SASL/CAP is also introduced. (#424)

Feature changes

  • 22ceb3f Added the sasl_timeout option for Clientbot networks (this defaults to 15 seconds if not set).

Internal improvements

  • Backported stability improvements from 1.2-dev:
    • d70ca9f Rewrite connection error handling to include RuntimeError and SystemExit (#438)

PyLink 1.1.1

The “Crush” release. Changes from 1.1.0:

Bug fixes

  • The pylink-mkpasswd program is actually installed now when using pip (PyPI) or setup.py.
  • Backported protocol module fixes from 1.2-dev:
    • unreal: fix crashes when receiving SJOIN with only a prefix and no UID
    • inspircd: work around extraneous letters sent in FJOIN timestamps (Anope 1.8.x bug)
    • nefarious: fix a typo causing crashes on user mode changes
  • Relay: in claim, show a less ambiguous error when a relay channel doesn’t exist on the caller’s network.
  • corecommands: removed extraneous irc.checkAuthenticated() call

Feature changes

  • pylink-mkpasswd now supports interactive password input via getpass, which is more secure than passing passwords raw on the command line.

Misc changes

  • More prominent migration notes regarding permissions and new accounts system.

PyLink 1.1.0

The “Calico” release. This is mostly a cleanup and documentation update from 1.1-beta2, with the following additional change: - Made passlib an optional dependency (password hashing will be disabled if passlib isn’t installed), simplifying the upgrade process.

For a full list of changes since 1.0.x, see the release notes for the 1.1 alpha & beta series. Summary of major changes since 1.0.x:

  • 🔐 Redone authentication configuration, now supporting multiple accounts, hashed passwords, and fine-tuned permissions.
    • Old configurations using login:user and login:password will still work, but are now deprecated. Consider migrating to the new login: block in the example config.
    • This also adds a new optional dependency of passlib (https://passlib.readthedocs.io/en/stable/), which is required for the password hashing portion.
  • Protocol modules now wrap long messages (SJOIN and MODE) to prevent cutoff shenanigans from happening.
    • This fixes a particularly nasty bug that can corrupt the TS on UnrealIRCd channels if a MODE command sets more than 12 modes at once (#393).
  • Added utilities to download contrib modules (pylink-contribdl) and hash passwords for the new accounts configuration (pylink-mkpasswd).
  • Most plugins were ported to the permissions API.
  • Clientbot now supports mode syncing, SASL (with optional reauth), and IRCv3 multi-prefix.
  • Services bots now support setting modes on themselves on join: see “joinmodes” in the example conf
  • Changehost gained a few new features, including optional (per network) vHost enforcement.
  • Added a bindhost option in server blocks, for multi-homed hosts.
  • PID file checking was implemented - Run PyLink with the --check-pid argument in order to turn it on.
  • The ts6 protocol module now supports KICK without arguments and legacy UID introduction (for older servers / services).
  • Relay: added a purge command to remove all relays involving a network.
  • Added support for ircd-ratbox (ratbox protocol module).
  • Changing the console log level via REHASH now works.
  • New servermaps plugin, displaying network /map’s from the PyLink server’s perspective.

PyLink 1.1-beta2

The “Conscience” release. Changes from 1.1-beta1:

Bug fixes

  • Protocol modules now wrap longer messages (SJOIN and MODE) to prevent cutoff shenanigans from happening.
    • This fixes a particularly nasty bug that can corrupt the TS on UnrealIRCd channels if a MODE command sets more than 12 modes at once (#393).
  • Pong handling is a lot less strict now (it just makes sure the sender is the uplink). In other words, fix issues on UnrealIRCd where PONGs get ignored if the argument doesn’t match the server name exactly (e.g. different case).
  • Clientbot protocol fixes:
    • Fix SASL PLAIN auth on Python 3.4 (TypeError with bytes formatting with %b).
    • Don’t repeat KICK hooks if the source is internal: this prevents KICK events from being relayed twice to Clientbot links, when the kicked user is also a Clientbot user.
    • Clientbot now explicitly sends /names after join, to guarantee a response.
    • Fix message recognition treating nick prefixes without ident@host as servers (this polluted the state)
    • Fix prefix mode changes for unknown/missing users in /who causing KeyError crashes
  • ts6: fix setting mode -k * not working due to wrongly ordered logic (1.1-dev regression)
  • ts6: fix handling of KICK without a reason argument
  • Automode: remove some repeated “Error:” text in error messages
  • IrcChannel no longer assumes +nt on new channels, as this is not necessarily correct

Feature changes

  • Changing the console log level via REHASH is now supported.
  • Added a bind host option for multi-homed hosts.

Internal improvements

  • updateTS now ignores any broken TS values lower than 750000, instead of propagating them (e.g. over relay) and making the problem worse.
  • The UnrealIRCd protocol module was updated to actually use extended SJOIN (SJ3). This should make bursts/startup more efficient, as modes, users, and bans are now sent together.

PyLink 1.1-beta1

The “Crunchy” release. This release includes all bug fixes from PyLink 1.0.4, along with the following:

Changes from 1.1-alpha1

Feature changes

  • Most plugins were ported to use the permissions API, meaning multiple accounts are actually useful now!
    • Having a PyLink login with new style accounts no longer implies access to everything on the PyLink daemon. See the updated example conf regarding the new permissions: block.
    • Logins implying admin access is limited to old accounts ONLY (i.e. logins defined via login:user/password)
    • The commands plugin now has permissions checks for echo, showuser, showchan, and status. The latter three are granted to all users (*!*@*) by default, while echo is restricted.
  • Clientbot now supports IRCv3 SASL (with optional reauth!) and multi-prefix. See the example conf for details on the former (the latter is enabled automatically when available).
  • PID file checking is now disabled by default for better migration from 1.0.x. Run PyLink with --check-pid in order to turn it on.
  • commands: add a new logout command (#370)
  • The list command now supports optionally filtering commands by plugin.

Bug fixes

  • The permission to use servermaps is now servermaps.map instead of servermap.map.
  • networks: fix the remote command to work with permissions (i.e. override the correct account name)
  • relay: add missing permissions check on the linked command

Internal fixes / improvements

  • relay: rewrite host normalization to whitelist instead of blacklist characters. This should improve compatibility with IRCds as previously untested characters are introduced.
  • relay_clientbot: faster colour hashing using built-in hash() instead of md5
  • opercmds: removed the source argument from kick and kill; it’s confusing and isn’t very useful

Misc. changes

  • Documentation updates: add a permissions reference, document advanced relay config, etc.

PyLink 1.0.4

Tagged as 1.0.4 by GLolol

The “Bonfire” release.

Bug fixes

  • protocols: implement basic nick collision detection in UID handlers. This fixes users potentially going missing on UnrealIRCd networks, if the remote IRCd introduces a user of the same nick after PyLink does. Thanks to kevin for reporting!
  • relay: strip underscores (_) from hosts on ts6 and ratbox, fixing possible invalid user@host errors
  • Backported fixes from 1.1.x / devel:
    • Demote “unknown user” warnings in mode handling to DEBUG, suppressing warnings when old services like Anope 1.8 set modes on users as they quit.
    • Fix irc.matchHost() confusing the realhost boolean to be the same as ip.
    • changehost: add missing permissions check to applyhosts; it now requires the changehost.applyhost permission.

Misc changes

  • networks: update help for disconnect to reflect how it now always disables autoconnect.

PyLink 1.1-alpha1

The “Candescent” release.

Changes from 1.0.3

Feature changes

  • Clientbot now supports optional mode syncing 🎉 See the example conf for how to configure it (look for “modesync”).
  • PID file checking has been implemented and is turned on by default. ⚠️ When upgrading from 1.0.x, remove pylink.pid before starting!
  • Revamped login configuration system, which now supports multiple accounts and hashed passwords
    • ⚠️ login:user and login:password are now deprecated and may be removed in a future release. Consider migrating to the new login: block in the example config.
    • Hashing new passwords can be done using the mkpasswd command via IRC, or the new command line utility pylink-mkpasswd.
  • Services bots now support setting modes on themselves on join: see “joinmodes” in the example conf
  • Added a contrib module downloader (pylink-contribdl)
  • Relay now uses the PyLink permission system. The following permissions are now available:
    • Granted to opers by default:
      • relay.create
      • relay.destroy
      • relay.claim
      • relay.link
      • relay.delink
      • relay.linkacl.view
      • relay.linkacl
    • Granted to all users by default:
      • relay.linked
    • And the following which is not explicitly granted:
      • relay.savedb
  • Relay: added a purge command to remove all relays involving a network
  • Automode now supports remote channel manipulation in the form netname#channel (#352)
  • protocols/ts6 now supports legacy UID introduction, for older servers / services
  • Changehost gained a few new features (look for “changehost:” in the example conf):
    • Optional (per network) vHost enforcement: now you can create spoofs like freenode without using their IRCd!
    • Enforcement exceptions for the feature above
    • Options to enable/disable matching users by IP and real host
  • New protocol support for ircd-ratbox, based off ts6
  • New servermaps plugin, displaying network /map’s from the PyLink server’s perspective. Relay links can be expanded as well to make this more detailed!
  • Oper status tracking is now a network-specific option, for better security. Look for “track_oper_statuses” in the example config.
  • The PyLink launcher now sets the terminal title on launch (Windows & POSIX)
  • relay: implement a complementary showchan command, showing a list of relay links

Bug fixes

  • Relay is potentially less crashy when PyLink is split off while it tries to introduce users (#354).
  • The bots plugin now allows JOIN/NICK/PART on all service bots
  • Relay: skip channel TS check for Clientbot (some users had this as a sporadic issue)
  • Irc: explicitly kill connect loop threads after an Irc object has been removed. This fixes various freezing issues caused by ghosted connections after a network splits (#351).
  • Relay: don’t error when removing a channel from a network that isn’t connected. (AttributeError on removeChannel() if irc.pseudoclient isn’t set)

Internal fixes / improvements

  • Server ID and service client name (if applicable) are now stored inside IrcUser objects, removing the need for some expensive reverse lookups
  • Relay and Automode now use a centralized DataStore (backwards compatible) in structures for their database implementation
  • Docstring rewrapping is now supported for neater, wrappable docstrings! (#307)
  • Irc.error() was added for easier error replies; it is a simple wrapper around Irc.reply()
  • Relay now uses locks in DB read/writes, for thread safety
  • Most camel case functions in Relay were renamed to lowercase with underscores (PEP 8)

Misc. changes

  • exec: Drop raw text logging to DEBUG to prevent information leakage (e.g. passwords on Clientbot)
  • Removed update.sh (my convenience script for locally building + running PyLink)

PyLink 1.0.3

Tagged as 1.0.3 by GLolol on 2016-11-20T04:51:11Z

The “Buoyant” release.

Changes from 1.0.2

Bug fixes

  • Fixed invalid database names such as “automode-/tmp/test.db” from being generated when PyLink is started with an absolute path to its config.
  • Backported fixes from 1.1-dev:
    • relay: skip channel TS checks for Clientbot, preventing possible “channel too old” errors on link.

Feature changes

  • Backported features from 1.1-dev:
    • Relay: allow configuring custom relay server suffixes

Misc. changes

  • Various spelling/grammar fixes in the example config.

PyLink 1.0.2

Tagged as 1.0.2 by GLolol on 2016-10-15T05:52:37Z

The “Baluga” release.

Changes from 1.0.1

Bug fixes

  • 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.

PyLink 1.0.1

Tagged as 1.0.1 by GLolol on 2016-10-06T02:13:42Z

The “Beam” release.

Changes from 1.0.0

Bug fixes

  • Fix PyLink being uninstallable via PyPI due to missing VERSION and README.md
  • ts6: don’t crash when CHGHOST target is a nick instead of UID
  • relay: clobber colour codes in hosts
  • bots: allow JOIN/NICK/QUIT on ServiceBot clients

PyLink 1.0.0

Tagged as 1.0.0 by GLolol on 2016-09-17T05:25:51Z

The “Benevolence” release.

Changes from 1.0-beta1

Bug fixes

  • 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).

Internal fixes / improvements

  • Fixed incomplete hook payload keys from 1.0-beta1 (oldchan/chandata -> channeldata)
  • services_support: hack away nick clashes between service clients & real users from Clientbot networks
  • clientbot: downgrade bad updateClient() calls to warning

Misc. changes

  • Documentation updates: Automode+permissions guide, README refresh, others.
  • Example configuration changes:
    • Automode’s bot nick now defaults to “Automode” instead of “ModeBot” for consistency.
    • Added a debug log example because nobody knew how to turn it on
    • Fix inverted option description for Relay’s show_netsplits option.

PyLink 1.0-beta1

Tagged as 1.0-beta1 by GLolol on 2016-09-03T07:49:12Z

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) .
  • relay: CLAIM is now more resistant to things like /OJOIN abuseSeriously people, show some respect for your linked networks ;).
  • 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.

PyLink 0.10-alpha1

Tagged as 0.10-alpha1 by 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)

PyLink 0.9.2

Tagged as 0.9.2 by GLolol on 2016-08-21T23:59:23Z

The “Acorn” release.

Changes from 0.9.1

Bug fixes

  • 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.

PyLink 0.9.1

Tagged as 0.9.1 by GLolol on 2016-08-07T03:05:01Z

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) that don’t explicitly use account names for logins (#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.

Misc. changes

  • Minor example configuration updates, including a mention of passwordless UnrealIRCd links by setting recvpass and sendpass to *.

PyLink 0.9.0

Tagged as 0.9.0 by GLolol on 2016-07-25T05:49:55Z

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-beta1

Added / changed / removed features
  • PyLink is now slightly more descriptive if you try to start it with missing dependencies or a missing conf file.
  • The PyLink API reference is now at https://pylink.github.io/ instead of in docs/technical.
  • The exec and eval commands now have access to the pylinkirc and importlib imports by default.
  • jupe from the opercmds plugin now requires the admin login instead of just oper.
  • opercmds: kick now treat channels case insensitively.
  • Documentation update: there are now guides to Automode and PyLink’s Services API.
Bug fixes
  • Fixed the reload command (again).
  • Fixed compatibility with ircmatch 1.2: PyLink previously used features that were only available in the unreleased Git version.
  • The identify command now responds with NOTICE instead of PM, behaving like any other command. Thanks to @Techman- for pointing this out.
  • The identify command must be called in private again.
  • Relay now shows secret channels in linked to those inside the channel, regardless of whether they’re opered.
  • $channel:#channel:prefixmode exttarget matching no longer raises errors if the target isn’t in the specified channel.
Internal improvements
  • Redone version handling so __init__.py isn’t committed anymore.
  • update.sh now passes arguments to the pylink launcher.

PyLink 0.9-beta1

Tagged as 0.9-beta1 by GLolol on 2016-07-14T02:11:07Z

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.

PyLink 0.9-alpha1

Tagged as 0.9-alpha1 by 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
  • 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()

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
