Feature differences from Xiph release
. FLV wrapping for mp3/aac listeners requesting it with ?type=.flv
. define a fixed number of worker threads (default 1) for processing clients
. allow for wildcards (*[] expansion) in mount-name and ban/allow files
. can limit mountpoint by outgoing bandwidth as well as a max listeners count
. can drop new listeners if server-wide bitrate is above a limit
. server xml reload, and reopen logging available via admin url
. When max-listeners reached, a HTTP 302 code can be sent to redirect
clients to alternative slave hosts.
. authenticated relays, those that match the relay user/pass, bypass the
max-listener/bandwidth check. slaves can use a different auth to listeners
. mount can filter out theora content, useful for defining a local relay
of a theora+vorbis stream to have a vorbis only stream from the same source.
. handlers setting for URL authenticator, for N requests at a time.
. allows for using seconds as a measure for the queue/min/burst sizes
. multiple ICY sources on single port
any extra tags are shown in the conf/icecast.xml.dist file
2.4.0-kh15
. Locking updates. For most, it will be no different but some platforms can be affected
. Keep consistency on the global listener count. Could of shown as very large number.
. Fix issue with fallback override of listeners. listeners being dropped
. Fix broken parameter to on-[dis]connect script on previous release.
. Small update for CORS handling.
. Fix YP updating. Long standing error flagged up on directory changes.
. Update for listeners moving between workers for load balancing.
. Small update for the FLV-aac wrapping in previous release.
. Fix up range request bug.
. Fix various log related issues.
. Some internal code cleanup
2.4.0-kh14
. Allow for using secs (eg 5s) in queue/min-queue/burst measures.
. Allow multiple icy sources on same port. Just embed in password a mountpoint:pass. The
shoutcast-mount tag still creates the +1 port and sets a default mountpoint but source
can override this.
. Fix log issue which could cause a deadlock if on-[dis]connect or auth cmd are used.
. Allow configure to accept ICY_CHARSET to set alternate in build. The default ICY
metadata is assumed to be UTF8, but some sites still have issues with setting tags or
parameters, so allow a different default if they need it.
. Regression on FLV wrapped aac metadata fixed.
. Crash/corruption fix if using stream auth and metadata updates via admin.
. Fix for glibc rwlock priority
. Added the icy-metadata in headers allowed with CORS
. Rework XFF to be earlier, useful in cases where banned IPs apply.
. Allow wildcards in XFF
. Drop the BSD NOPUSH setting for now. Have seen poor performance because of it in
certain cases
. Openssl API cleanups. eg API differences between versions.
. various small fixes, build and operational.
2.4.0-kh13
. Fix an annoying race case. memory corruption in certain cases that are hard to trigger
normally but typically involes a listener disconnecting in certain conditions.
. tightened up use-after-free cases with regard to the queue pruning.
. leak fixes with intro via auth.
. Allow seconds to be specified in burst and queue size fields. Just specify the number followed by s
eg 30s or 5s. Eventually we could make this the default so that is can apply to various
bitrates.
. small minor cleanups across the board.
2.4.0-kh12
. fix up some incorrect or stale block cases from previous release for non-ogg streams. Usually
cause by short write triggers or queue jumps.
. change default charset for non-ogg streams to utf8 instead of latin1, you ca still use
latin1 either with <charset> mount setting or charset= query param to metadata
. global listeners count could get messed up with fallback to files, also make it a regular
update stat in-line with other global stats.
. avoid possible crash case on log re-opening, not so common.
2.4.0-kh11
. fix issue with timelimited listeners and html5 players with range requests
. security fix for auth url when allowing certain headers to be passed.
. fix for mpeg block expansion handling, led to cases of parsing failures
. block scaling changes for mpeg based streams.
. internal restructure for metadata on non-ogg streams. For code maintainability.
. bounce admin mount request clients to worker with the source, reduces lock contention with lots of sources
2.4.0-kh10
. stop ID3 in streams for now, some browsers can have playback problems.
. fix memory leak case in the queue from previous release.
. fix crash bug on source timeout
. various internal changes for building, rate calculations
2.4.0-kh9
. pre-roll logging options. like access log but report client details of intros played. Can be
per-mount or global. Also allow for IP recording to prevent intro play if reconnected within
N seconds.
. add tag ssl-cafile to refer to a CA bundle other than the default. This way the cert is not
required to include it.
. allow /admin/metadata to accept param intro or preroll to change the intro file used on a source.
. split explicit mounts from list into a tree for quick lookup. speeds up updating with many mount
definitions.
. max-listeners setting in limits for server wide limitations.
. worker balancing updates. avoid a lot of bouncing between workers for sources and allow more
listeners to be attracted to their source worker.
. clean up shutdown procedure for race handling.
. smaller SSL handling cleanup.
. log messaging update.
. mpeg parsing updates. Allows for better detection and reporting, identifies mismatches better,
and detects a few more frame types. The sync structure is also reduced so should help in caching.
. rate averaging update.
. minor tuning for intro drops, fix for 0- range requests and intros.
. delay opening intro file until stream has started up, allows for format matching.
. lessen write lock scope when reading xml.
. failing to bind a socket at startup should be a termination event, although not on a reload.
2.4.0-kh8
. Logging. An issue was reported on log cycling triggers, should be the last now. This time it
seems to stem from a cycle triggered externally where a new log is created for appending before
doing the reopen. This is now fixed.
. Expand the worker limiter when processing lots of clients in one pass. This was leading to
some seeing sources not getting cleaned up as the listeners were not getting serviced. There
is still a cap but is extermely large and can be bypassed on cleanup cases.
. Incoming worker thread added. Normally incoming clients, after passing the initial IP checks
get passed on to worker threads for subsequent pocessing. This can lead to a lot of wakeup
for the usual worker threads to process these especially if they are short (eg playlist) or
involve filtering or kicking off auth. The extreme case being a DoS type of thing, where the
wakeup often causes the worker to do a big list traversal slowing things down as it gets busy.
This new worker thread deals with the initial aspects, http parsing, initial request handling
and is only moved to the normal workers for sources, listeners and some static content.
. Add "headers" and "header_prefix" options onto auth url. To bring into line with the Xiph
build. It is possible that some sites would want to inspect certain headers passed by
clients to authenticate. We do not want to pass all of them as that can be large and for such
situations, particular headers are limited, the prime example of these is cookies. To avoid
POST tag name clashes with existing established tags passed in aurl auth, these headers are
supplied with a prefix, defaulting to "ClientHeader-"
. Stats. A number of global stats are now reported every 10 seconds or the next second if
they have changed. This reduces load on a stats link and can save on logging if you have
that level enabled.
. A small set of code cleanups
2.4.0-kh7
. fix up recent ssl update to build against openssl 1.1
. drop range requests on streams, was breaking iOS 11.
. log typo fix
2.4.0-kh6
. drop client is read channel is closed off, handles proxies better like AWS.
. Logging
better log messaging at startup if change owner used.
fixed race bug generally affecting the per-mount logs, excessive purging.
fix auto log cyclying
. Add listeners= to POST on auth url. current listener count in the stats
. internal improvement to cached entries for addresses
. SSL updates
build fix where no SSL is available
allow for DH/ECDH
allow for reading the cert before dropping privs, but keep certificate if reload is fails.
crash fix if no SSL certificate defined.
small fix for internal openssl threading.
2.4.0-kh5
. use a separate thread for logging, prevents worker stalls in certain setups.
. backward compatibile playlist archive setting fix.
. update IPv6 handling. This is really an internal update but allows for both
IPv4/IPv6 listening sockets to be created from one listen-socket block. This
allows for windows builds to have IPv6 as well.
. autodetect SSL connections on incoming sockets. No need for <ssl> in listen-socket
now but is still there for compatability.
. add <ssl-private-key> in <paths> to allow for combined PEM or for separate SSL
key/certificate files.
. select https/http URL in autogenerated m3u based on incoming request.
. minor update to windows service creation. No functional change

how long the relay will continue with no listeners.
. prevent memory leak with short send xsl requests.
. added message for excessively long duration spent going through a worker client list.
. for cached lists like banned IPs, place wildcards separately to fully specified entries,
as the matching broke in such cases. The wildcards list now separate from the tree.
. add the nodelay thing back in, normally if doesn't make a difference but in certain
cases it can affect packet scheduling and cause stalls. Seen on very high bitrates.
. added cipher list tag for compatibility with recent icecast 2.4.x builds

. introduce lazy slave stats update for updating virtual mountpoints, this reduces
the stats generated if you have many mountpoints with frequent starts and stops.
. drop PE substitution in metadata, only do the likes of &
. allow for source queue shrinkage. With the rwlock merging, the queues were left to expand to
queue-size whether listeners were lagging or not, this helps reduce unwanted parts of the queue.
. allow for listener processing to be skipped if it would stall waiting on lock.
. stats link update, like issuiing NEW commands first at connection before EVENT, not
important for most people
. Various log message updates and small scale lock range updates.
2.3.3-kh6

. burst size of less than 1400 was not handled correctly with recent rwlock changes
. some memory reduction for FLV listeners.
. Missing xsl could cause a busy loop.
. fixed a crash when listener reached end of the queue. Certain assumptions about buffer
of queue accounting were changed with rwlocks, exposed a crash case.
. on some multi-processor setups, it was possible that certain listeners could trigger
a busy worker due to old (cached?) data, work around applied.
. A listener that started off a new on-demand relay could be only partially initialised
a lead to a crash later on
. report of recent flash update on FF15 when requesting non-FLV content. Expected header
identifying flash is no longer present so now we check for swf in referer.
. Add short write handler for clients requesting short ranges (eg Apple)
. The stats handle for normal file or fallback files were altered in a previous release
which prevented a lookup of listener details via admin requests. now fixed.

. missing delay for blocking file client, has an effect of higher cpu usage
. rare override failure case handled better.
. various minor fixes, including log format, memory leak and stats.
2.3.3-kh1
. Big change with rwlocks replacing mutexes. It's internal but can have a big effect
on load pattern usage. In cases with many listeners on a single mount we can now
spread clients across all workers. A number of balancing changes were done to
assist in localising related clients but may need more tweaking. A side effect
of these changes is that queues are only shrunk when there are no listeners, so
queues can take up more memory than usual but that could of happened before.
. fix bad reference for file-based content like intro/fallback with FLV
. make the minimum duration of an on-demand relay last until it would be classed as
working, any less then it could be skipped or disabled for a short time.
. skip entity decoding if none required. For cases where metadata has & causing
the libxml2 to spit out warnings like "no name".
. If no sockets are opened at the start then exit.
. Win32. standardize on format for date, back to proper timezone numbers
. Log AAC samplerate change in stream.

auth handling if disabled and busy relay restarting.
2.3.2-kh33
. Expand file open limit to match <clients> if possible, warn if less.
. Fix possible client leak. legacy code removal.
. updated mpeg parser to be more specific on bits to match for. It should increase
the tolerance for changes in the stream format (CRC, samplerate etc).
. reload forces an update of active streams, was missing from a previous update.
. Realplayer based apps fix for aac+. Assumes certain response header.
. drop requirement for matching each / in mount-name.

. Experimental. send variable block framing if requested by listener
. Experimental. allow <include>/dir/*.xml</include> in <icecast> for breaking xml up
. Experimental. webm work by David Richards
. Experimental. source client hijacking. replace existing source with another. has to
to allowed via auth url currently to prevent bouncing of clients with auto-reconnect.
. Add duration to all access, error and playlist logs, allows re-opening them after a
number of seconds elapsed, 0 by default. set size trigger to 50Meg default.

. sync up headers handled by auth cmd with auth url.
. Added missing stream format checks for certain error cases.
. speedup for icy metadata and avoid length bug on inline urls.
. A number of possible lock fixes and checks are now added for odd cases.
2.3.2-kh31
. Add generic scattered IO routines, listeners wanting FLV wrapping now use this which
saves a lot of memory copying and therefore load.
. build setup for mingw32. This should help with library updates for us, drop GUI build
. relay restarting fixes included for certain error cases. relays are treaated as
failed if they stop within 60 seconds and skip on to next server if specified.
. a better trigger for on-demand relay if fallback has listeners.
. on reload when changeowner used, allow for listening sockets to be reopend but
prevent closing priviledged ports unless missing from xml
. prevent unescape routine from creating non-printable chars
. ignore per-mount username when source is using shoutcast protocol.
. URL auth can now accept a "ice-username: ..." in the response headers for setting the
username. For setups that use query args for auth
. expand args applied to xsl requests, url encoded now.
. modify k and m in bitrates to be on 1000 not 1024
. accesslog modification to parsing, optionally set <type> in <accesslog> to CLF-ESC
to escape-encode strings instead of using "".
. if falling back to file, the bitrate used takes, in order of priority, incoming
bitrate, limit-rate and then [value] in filename eg /fallback-[128]
. fix a large ogg page bug, flac is probably the only one showing this up currently
. fix a couple of rare crash cases with file serving clients.

shared lock.
. minor log message changes.
. fix fallback trigger if source timeout occurs
. fix possible sources count inconsistency with failed relays
. entity expansion in stats conversion routines added
. fixup debug allocation code. not normally used.
2.3.2-kh30
. stats updates.
Split stats lock into global and source stats locks, reduces contention.
Updated internal API for using a stats handle for quick lookup when updating
several stats at once.
Make metadata_updated stat to be sent last in the initial listing, we would want
that to appear after title, useful as a trigger for updates.
make NEW also report the content type after the mountpoint
. re-work metadata insert merge with shoutcast inserts for mp3/aac, do metadata
followed by stream data instead of the other way around, reduces code.
. fix url decode crash bug with %invalid code.
. prevent yp add if required data is missing.
. allow for all args to be supplied to xsl transforms from request not just mount
. xsl transforms are written direct to refbufs, so should avoid a memory copy on
each transform, should help in cases of large data sets.
. Add redirect tag on <mount>
. change default to allow ogg matadata via url (for consistency with trunk).
. have master relays supply auth by default.
. allow for quick responses to be tried and possible close the connection, saves
rescheduling the worker for just closing the socket.

2.3.2 master.
. reduce duration of when the config write lock is held when doing reload.
. a number of tunings for rescheduling clients (source and stats mainly).
. small reworking of client_t creation and accounting.

. automatically set nofile and corefile size limits to max allowed, for debug
2.3.2-kh29
. prevent crash with very small burst size (eg 0).
. fix possible race with relay restart and headers used in stats update
. fix possible mpeg issues causing a crash or getting stuck in an allocation loop on bad input.
. An FLV listener could trigger a corruption in the metadata for non-FLV listeners. More likely
to occur when starting on-demand relays.
. relays that have only been connected for a few seconds will be treated as if it had failed to
restart and listeners will be droped or moved.
. fix possible server stall if reload requested and auth listeners were pending on auth queue
. Fix a number of cases where listeners kept a relay from restarting because of an incorrect
internal state, a stuck relay.
. revert to reserving a new relay source later in client processing. The relay is still installed
immediately (with client) but the source could clash with another already reserved.
. listener triggers wakeup of inactive on-demand relay, which allows us to reduce the scheduling
of inactive relay clients.
. when relays are updated, only wakeup workers once, not for each relay.
. stats cleanup on disabled or failed relay start
. on-demand relays minimum transfer set to 2Meg
. make rejected_mount and stream_auth work properly again for URL auth
. possible listener cleanup race if auth used at exit. We now keep listener on the worker even
if inactive until complete.
. expanded FLV metadata, double and bool settings, adds audiocodecid, audiosamplerate, stereo and
various entries from stats.
. slave relay could of been redirected, now it is marked as a slave by the master so bypassess
various limit checks.
. If auth server does not respond then disable URL requests for listeners for 60 seconds. Keeps
icecast from clogging up if link to auth server breaks. Some people use auth for non-auth
accounting or listener intro, so extra option added to allow those by default (option
presume_innocent set to yes to allow listener even if auth not active).
. Make auth refcount change based on threads holding it not clients, simplifies the shutdown or
busy startup case.
. move non-ogg metadata update code into one place, and fix-up use of inline URL parsing and
possible short write in rare cases.
. slow down listener thread (therefore reduce new incoming listeners) if relay starts up, more
so if many relays start or auth queues are full.
. increase internal settings, max auth handlers to 100, auth queue to 300 and listen queue to 64
. fix ogg stream dump-file.
. reduce frequency of rebalancing across workers with many streams, reduces lock contention
. use alloca instead of malloc for non-ogg metadata/stream merge, minor speedup
. new listeners (with queryargs or user:pass) redirected because of icecast will
have their supplied auth details added to new location.
. recreate worker pipe if it fails or else we could busy loop.
. add error code to recoverable list for accept, and prevent listener thread slow down in those
cases, seems to affect FreeBSD more than others although it could affect others.
. revert listener stat names for listclients to 2.3.2 case for now
. minor log message cleanups.
2.3.2-kh28
. fix possible short send shoutcast metadata inserts getting corrupted
. fix a few possible flv issues when metadata is missing.
. add filter routine for mpeg parsing, used for file inputs like intro or fallback
. add mpeg ts frame marker to frame alignment code.
. add min-queue-size mount setting, defaults to burst size so backward compatible.
players can request anything up to min-queue-setting with the initial-burst
header or burst= arg
. worker shutdown forces clients to process, should allow for quicker termination
or moving to another worker.
. stats client tidy up, prevent a few more stats going through to slave, report
slave auth failure properly, and initialize settings for inc/dec updates
. introduce SYNC flag to source to keep internal counts consistent when moving or
terminating listeners
. add proxy/cache avoidance headers
. drop start timer from relay as we use the more general client schedule timer
. removed the relay recheck each second as the relays are now installed and started
via the clients on the workers. saves work with many relays.
. possible crash point on relay details change, or xml reload
. offset in file serving was always 0 even if range was requested.
. add in the 7.xsl hack for compatability
. A few internal code and log message cleanups.
2.3.2-kh27
. use the tree locks instead of stats lock, this should lessen contention with many
stats updates, typicaly of setups with many streams.
. rework previous non-ogg metadata short-write fix, was not complete.
. previous non-ogg metadata fix exposed problem if file fallback used.
. remove possible race waking up a worker, could result in crash.
. add <max-stream-duration> to <mount> (in seconds), could even be used to cycle
dump files on a relay.
. leave public setting as-is when on-demand relay stops.
. minor legacy code cleanup
2.3.2-kh26
. fix possible content corruption on shoutcast metadata inserted streams if a short
send occurs during metadata sending.
. do not list non-hidden streams in /admin/stream[list|streams] and make sure auth
applies to /admin/streams.
. allow for the so-sndbuf option per-mount as well as on all connections.
. old style bind-address setting (not listen-socket) was not working
. allow a negative ban-client value to use the internal deny block of IPs to prevent
more than 1 IP connecting at the same time.
. small code changes for main worker thread
2.3.2-kh25
. FLV clients could skip frames on a truncated write, leading to playback problems.
. various client scheduling tunings, allows quicker reschedule when only some data
was written. This seems to affect win32 more than others, especially with burst
. fix shoutcast-inline metadata bug involving a URL
. per listener mpeg checking only verifies 1 frame as queue is already checked
. set non-ogg intial blocksize to 1400 again, now that blocks can be more flexible
in size
. filter out multiple / in requests
. the 2.3 log archive setting wasn't handled correctly.
. certain relay configuration (multiple addresses) could leak a file descriptor
on failure.
. possible NULL pointer crash in metadata update.
. possible sources count not decreased if relay fails.
. fix for possible relay change restart
. worker lock changes, now we only take the lock when adding clients. This reduces
some lock order complexity when moving clients around and means that no locking
is done for most of the time.
. relay changes are tagged and changed by the client functions.
. compile cleanups
2.3.2-kh24
. Allow for per-listener wrapping of existing mp3/aac streams when requested with
a type=.flv as a query arg. The actual trigger could be anything we want but this
allows for using the existing mountpoint, with easy mapping for URL auth and for
matching an extension in the player. Works with intro and fallback handling.
. mpeg parser is more complete, handles more cases, avoiding bad input cases
. fix possible bad pointer in ogg headers case.
. fix for shoutcast-style metadata writes being truncated.
. fixes for non-ogg buffer alignment causing resync or stalled streams.
. prevent a failed stream list request from dropping current relays
. handle relay startup shutdown better for memory usage and listeners
. use Host header if available for buildm3u
2.3.2-kh23
. if an inactive on-demand relay detects listeners on fallback then start relay
but do not move listeners until the connection is complete.
. fix race condition with restarting non-ogg relays and stats being generated
. make auth queue limit 150 before rejection.
. A number of relay related fixes. these typically occur when a relay is either
restarted or was removed (eg disappeared from a master). There is also a
possible case of long held locking that is now gone.
. add <ban-client>N</ban-client> mount option to add client IP to the internal
banned list for N seconds. subsequent attempts that have not timed out extend
the ban period. A stat count of banned entries is produced each second
. reload from admin page was not restarting listen thread if signalfd used.
. increase default queue block size on non-ogg streams to 2900
. mpeg parsing fix for odd cases. This could appear as corrupt or stalled streams
. fix listing of stats and listener details on fallback files
. fix Location header reference from auth url
2.3.2-kh22
. Add mp3/aac sync marker alignment code. This makes the internal buffers contain
whole frames. allows for better transistion when moving listeners.
. The number of logs is not limited to 25 now
. small changes to client scheduling
. removed format url lock, source lock is always taken, so this is not needed
. Add <skip-accesslog> boolean to per-mount settings. Prevents logging listener
client details to access log
. evaluate bandwidth usage when adding to the global bitrate, and change throttle
indicator if max bandwidth specified. listeners have varying degrees of
scheduling limits applied. lagging listeners get delayed first, then all do.
. fix long standing bug which could cause a crash on a bad xsl.
. report line numbers on xml errors.
. small work-around to handle odd handling of ICY response for mpc and expected
the content-type header for shoutcast relay and streamtranscoder.
. kh21a. kh20 introduced a bug which could occur with listeners being moved between
workers.
2.3.2-kh21
. Fix possible stall bug when a source exits and when adding a listener, only
keep the source_tree lock held until a source lock can be acquired.
. tighten up where the certain locks are held/released.
. win32 stat return code fix
. added a few internal checks and some log messages.
. fixes from moo, #1646, status response header first always, #1648, return ICY
response for mpc
. make fh_node use tree for quick lookup
. zero out format structure, remove previous stats for restarting relays
. NULL pointer fix in cases where a relay was being cleared of listeners without
a fallback mount, eg being disabled or removed from slave list or reread XML
2.3.2-kh20
. fix possible lock imbalance bug if mutliple workers set
. make sure listeners are not paused if relay is not running
. fix memory leak on each source disconnection.
. fix double free corruption bug if listener_remove used.
. on server shutdown, prevent auth of new listeners only. other auth requests
can continue which allows client details to clean up properly
. relocate where the source count is increased. For source clients it is just
before where it used to be but for relays it is increased before a relay
connection is attempted. Bug in kh19 meant sources kept increasing on relay
restart
. fix possible stalling bug in auth command method.
. listener_connections stat could have a random data bug
. Do not force a master relay recheck on stream start/stop
. build fix on certain platforms.
. small internal code cleanups.
2.3.2-kh19
. add 7.xsl processing to present stats for a shoutcast /7.html request, requires
alias of /7.html to /7.xsl
. avl tree of listeners is back in, workers process lists of clients but the tree
enables a quick listener lookup from a source.
. the admin arg require handler left a lock held if not specified.
. make sure the allow/deny/useragent files reload properly
. initialisation bug for auth, more likely to affect win32 gui.
. content-type has to be lower case for shoutcast to recognise the mime type.
. per-mount access log. <accesslog> <name>/file.log</name> ....
. update to the source shutdown process. reduces code in relay shutdown, no point
in duplication. allow listeners to be placed in a waiting state if source is
waiting to start up.
. do not dump stream stats on on-demand relay failure.
. allow for reporting xml parser warnings to stderr at startup
. fix possible auth related corruption with disconnected clients on slow auth
. type fixup on lag calculation on 32bit systems.
. if streamlist fails then drop all slave relays.
2.3.2-kh18
. for people who use ICE_MUTEX_ABORT (environment var) to trap for long held
locks, change the name to ICE_LOCK_ABORT
. fix possible memory corruption case in stats and threading
. fix vorbis stream bandwidth increase when certain source clients connect
. avoid any ::ffff: in IPs
. YP thread now started from worker as required instead of once per second
. shutdown order and other internal code cleanups
. use signalfd if available for processing signals in connection thread, saves
waking up the thread.
. make sure the auth mountpoint returned is used instead of the listener
supplied one. Allows for redirecting listeners to alternative mounts
. update command auth, works in a similar way to url auth now.
. stats clients work better under much heavier load. stats notifications
are grouped together if possible before sending, this reduces writes in the
many streams case
2.3.2-kh17
. fix possible memory corruption when using multiple workers
. a few minor timing changes, nothing major.
. fix possible race case in multiple file handle close
. kh16b. fix possible crash case with relay failing
. kh16a. some fserve changes exposed a crash bug with flash clients.
2.3.2-kh16
. you can now fallback to file if the initial mountpont is not available as long
as there is a limit-rate set at some point within the fallback chain.
. A header from url listener add "icecast-auth-user: withintro" indicates that
the response contains intro data to be sent to the this listener. Anything
else indicates the previous behaviour.
. allow source clients to be limited by duration, set by time limit header in
url stream auth
. internal changes to average bitrate calculations. blocks are now removed based
on the timestamp not the block count.
. fix possible race with url auth'd listener getting a 404 response
. try throttle file sending based on duration/bytes sent on file handle and split the
file sending function into two (throttled/unthrottled). reduces memory.
. merge in compile-time allocation counters
. Added some stats for fallback files, and metadata_updated for sources
. minor cleanups for internal API. log message cleanups.
. kh15b. fix possible crash on url listener failing.
. kh15a
- fix memory corruption when clients are referring to the same file.
- log buffering on win32 enabled
2.3.2-kh15
. lock mismatch identified, could cause a stall in the worker.
. relay connection timeout was not being set in all cases
. Don't fallback listeners on relay fail if server shutting down
. minor code cleanups.
2.3.2-kh14
. Allow stats/listclients/killclient work with file references
. Add timeout parameter to relay. number of seconds for connect to complete.
. fixes for restarting of relays, especially where changes are detected and
where fallback to files were set.
. repeat fallback file
. tuneup client scheduling for file sending
. added a few validation checks, useragent chars, xml config port ranges
. log message cleanups.
2.3.2-kh13
. on source exit, listeners do not need to be moved to the file serving engine,
just release any shared data and delete client if not on worker. saves process
work at source exit
. fix possible crash bug with long lock held detection.
. allow listener_add response to include intro content
. merge connection_t into client_t, and shrunk connection_t, reduces memory used
. improve some of the internal client scheduling.
. the reading of the mime types file was done too early
. admin/fallback now updates the mount details if available.
. more source lock cleanups. nothing major
. change the order of the header routines, the format specific routine now calls
the general routine.
2.3.2-kh12
. xml based relays could cause a crash on server exit or xml reload
. avoid memory/fd leak on active relay restart.
. cleaner worker thread shutdown.
. win32 update. Prevent Esc closing the GUI. Make the service work better and
is now able to take an alternative xml as parameter. Update libogg in the
build to 1.1.4 and refer to the current directory for dependent DLLs.
2.3.2-kh11
. busy looping caused by truncation on 32bit setups
. avoid possible deadlock between file release and open
. relay client handles were not being cleaned up fully.
. send Host: header on relay connects.
2.3.2-kh10
. big internal thread change. instead of one thread per stream, we now have a fixed number
of worker threads, each processing a set of clients (sources/relays/listeners etc).
- no source or fserve threads now. auth still has thread(s) as the API for libcurl
is blocking
- worker threads with no clients sleep for long durations.
- defaults to 1 worker thread, overridden by <workers> in <limits>
- listeners get moved to the worker thread running the source, helps caching
- sources get moved to a less busy thread if it would help
- each client has a timestamp to indicate when it wants service. The sleep duration
for the worker is based on the next client to be serviced.
. if fallback to file is specified and the requested mount is not active then a 404
response is returned instead of the file contents.
. fserve engine can handle bandwidth limiting per client. Fallback to file uses this
by using the average incoming bitrate of the source stream as the target limit.
. file serving uses an internal cache of open files, so that 1000 listerners do not
suddenly open 1000 files if a fallback to file occurs.
. move listeners admin request can specify another source or file.
. relay changes
- the client structure is always allocated now, instead of when the relay is started.
- listeners stay on relay if switching to another relay master. Only when they all
have failed does the fallback apply.
. post-kh9 fixes
- fix for possible race with rejected new listeners going through auth
- make mp3-metadata-interval 0 work again
- auth htpasswd checks for details provided like user:pass@host:port/mount and if not
then checks as host:port/mount?user=a&pass=b
2.3.2-kh9
. allow shoutcast source client auth work via stream_auth url
. allow for a flash policy file.
. internal cleanup to help merging into trunk
. fix vorbis metadata update via url, broken in recent releases. cleanup some metadata
updating/logging
. drop vorbis stream rebuilding back to flush evert half second, in sync with trunk
. stop false reports of 'not null' in debug logging. no other effect on server
. limit how often the relay mountpoint "already exists" logs.
. minor tweaking to the average bitrate calculation
. remove the internal global time caching, although prevent several time calls if in
succession.
2.3.2-kh8
. fix memory corruption which affected ogg streams.
. fix for unsupported FBSD/win32 spin locking options. abort on initialisation failure.
. win32 fix from kh7 causing stalling source threads. fallout from kh7 build failure
2.3.2-kh7
. merge fix for bug report on trunk for skeleton
. fix for build failure with recent glibc
. fix for admin.cgi metdata updates not applying (kh5 bug).
. minor locking cleanup
. win32 fixes. server restart could cause relay details to become corrupted
. win32 update. updated libxml2/libxslt
2.3.2-kh6
. some source stats were not being reported on the xsl pages.
. win32 access log timestamps should now to correct.
2.3.2-kh5
. stats fixes, crash case in stats handling, and hidden attribute was not honoured
on xsl pages with recent stats changes.
. if requesting /admin/streams via stats method then allow auth via relay user/pass
or mountpoint auth. receives only stats for slaves
. allow url= tag on metadata update for non-ogg streams, adds StreamUrl.
. fixed possible crash with skeleton stream handling
. actually prevent metadata updates if there is a stream already running from a
different IP.
. fix build bug on FBSD7
. allow optional queue-len tag in listen-socket, default is 10
2.3.2-kh4
. Where's the brown paper bag. boolean settings in the xml were being ignored due
to an incorrect test.
2.3.2-kh3
. fixed master not informing slaves of streams bug. caused by missed setting in
the kh2 stats update
. more xml checks for badly formed xml files.
. log files can now be sections not just a single filename ie <errorlog> can
contain <name> <archive> <display> and <level>, accesslog can contain <name>
<ip> and <archive>, playlistlog can contain <name> <archive> <display>. In each
case, name is a filename, archive is a true/false setting for using timestamps
on a reopened file, display is the number of lines to show in the admin page.
2.3.2-kh2
. more stats work. Clients are now processed as needed instead of a dedicated
thread per stats client.
. don't allow raw metadata updates if not from the same IP address as the source
client unless it is from the admin user. For some reason some source client
issue updates even though they are rejected.
. missing lock on streamlist master/slave update, could cause memory corruption.
. update to average bitrate handling.
. allow strftime expansion on dump filename, applies at the time the stream has
started
. removed debian directory, it's not maintained really so leave it to the debian
people to deal with it themselves.
. experimental theora keyframe as png patch added. not built by default
. minor memory leak plugged in fserve
2.3.2-kh1
. remove stats thread. Stats clients still have their own thread and queue.
. fix low bandwidth theora stream problem.
. failing on-demand relays were not being recovered as they should of.
. encode xml entity data for clients useragent/username
. reduce memory usage in avl nodes, seems to benefit win32 more because of the
unused lock handling
. minor patch for kate detection applied. ogg.k.ogg.k
. minor type cleanup for off_t in fserve
2.3-kh34
. Added Kate/Skeleton codec handling within Ogg streams. patch by ogg.k.ogg.k
. small changes for stream directory handling, mostly for error cases.
. added /admin/reset?mount=/mountpoint&setting=x to reset stats for that mountpoint.
without setting= all resetable stats are reset. x can specify peak,read or send
or a combination of them (comma deliminated)
. /admin/streamlist.txt uses the same routine as /admin/streams so does not have
a limit on how much is sent back.
. updated win32 code, windows service should be ok again. service name now
includes version to help multiple installs but windows may require a reboot
between removing a service and installing that same service again.
. fix possible crash on reload of xml with bad tags
. small update of web pages
. added per-mount stat for total mbytes sent
2.3-kh33
. master/slave update.
slave mode only issues a streamlist.txt request if the /admin/streams request
fails. /admin/streams also acts as an mountpoint for the slave relays by
passing a mount= arg and auth.
You can now define a <mount> for /admin/streams to define how slave
authentication is done eg url (listener_add) or htpasswd.
Once authenticated, the slave can bypass any limits like max listeners etc.
The slave also allows for defining a <master> tag block instead of <master-*>
tags allowed are <username> <password> <server> <port> <redirect> <bind>
auth url can take an "icecast-slave: 1" header, which makes client act as a
slave and bypass mount limits.
. build fixups for OpenBSD and cases where IPV6_V6ONLY is missing
. move 'clients' limit check to after admin request check, means admin commands
can work even if the limit is reached. removes a lock taken as well.
. drop connections to known slave relays if we find that the destination source
is a fallback to file, as this would cause high bandwidth usage.
. stats fix for inactive on-demand relay stats without a mount definition.
. added some minor consistency checks.
2.3-kh32
. crash fix for a failing on-demand relay.
. incorrect logfile settings for timestamp setting, for playlist and access.log
. update for win32 build and initialization.
2.3-kh31
. hard to trigger but possible race condition on source startup.
. long standing bug identified with many descriptors (eg > 1024 listeners)
. allow YP thread to skip a non-responsive server.
2.3-kh30
. crash fix if no user/pass supplied when stream_auth in use.
. the admin=1 was not passed in POST for stream_auth on metadata updates
2.3-kh29
. some small code re-organisation in kh28 caused auth htpasswd to fail new
listeners
. work around FBSD issue with listening on IPv4/IPv6 sockets
2.3-kh28
. race fix in yp thread startup.
. manageauth userlist page was blank due to a NULL check, fixed.
. add rejected_mount auth option to redirect unathenticated listeners to an
alternative mountpoint. eg subscription stream redirected to low bitrate
. Allow for url auth to handle 'Mountpoint: ' header for redirecting listeners
if they are to be rejected to an alternative mountpoint on the same server.
This is as opposed to the Location: header which gets a player to redirect,
maybe to an alternative server.
2.3-kh27
. fix potential fserve thread race
. merge listener inline shoutcast metadata into previous block write. It is
very common and saves writing a very short packet per listener at metadata.
. reduce log memory usage when caching lines for web display
