Changes in 0.6.0, released on 2015-01-18:
* This release contains a SECURITY FIX for a command injection vulnerability
that was found and reported by Alexandre Rebert:
The previous handling of metadata placeholders allowed for arbitrary shell
commands to be trivially injected and executed as the ezstream user, via
malicious media files.
This vulnerability depends on both a configuration using metadata
placeholders and the user streaming media files from untrusted sources
without noticing `commands` or $(commands) in artist or title fields.
While the group of actually affected users may be limited, all users are
advised to upgrade.
* This release requires users to ADJUST their CONFIGURATION:
To protect against the injection vulnerability above, metadata is now
properly quoted and escaped from the shell. This means that any extra
quoting must be removed from configuration files.
Remove all quoting from metadata placeholders in <encode/> and <decode/>
commands, e.g. replace "@M@" with @M@, and "@T@" with @T@, etc. Without
these changes, stream metadata will look both wrong and the injection
vulnerability may be re-introduced.
Configuration examples have been adjusted accordingly.
* src/ezstream.c:
- [FIX] Prevent certain characters from being interpreted by the shell.
- [FIX] Prevent ezstream from entering an infinite loop when stopping to
send data to standard input. From gquintard.
(Ticket #2045)
* various:
- [NEW] Add new <metadata_refreshinterval/> feature from Matthew Adams
(with minor changes plus documentation.) This allows for recurring
and custom metadata updates in between song changes via
<metadata_progname/>.
- [NEW] Add new command line option `-m' to disable any active metadata
updates. Idea from Richard Thomas.
(Ticket #1620)
Changes in 0.5.6, released on 2009-08-31:
* ezstream-file.sh:
- [NEW] Add and install ezstream-file.sh, a new convenience shell script
that generates configuration and playlist from a template and
command line, respectively. (Bourne shell and POSIX utilities
required.)
See ezstream-file.sh(1) for details.
* src/ezstream.c:
- [MISC] Be more tolerant towards faulty playlists and similar issues.
Failure to open a resource (e.g. a media file) is no longer fatal
and operation will continue until 100 subsequent errors. Based on
an idea from dhorton.
(Ticket #1585)
- [NEW] New command line option -s: Make ezstream function as a line-
based shuffling utility.
* src/playlist.c:
- [MISC] Consider no output from a playlist program to be equivalent to an
empty line, indicating that the end of the playlist is reached.
- [FIX] Do not complain when receiving an empty line from a playlist
program.
* examples/:
- [NEW] Add a real-world example playlist script with logging feature.
Changes in 0.5.5, released on 2009-08-01:
* win32/config.h:
- [FIX] Re-enable TagLib support in MSVC build. Found by Roman Donchenko.
(Ticket #1535)
* various:
- [NEW] New optional <sourceuser/> configuration option, to change the
username used in authentication with Icecast. Suggested by
Akos Veres.
- [MISC] Further improvements and minor fixes in the build system.
Changes in 0.5.4, released on 2009-03-28:
* compat/sys/tree.*:
- [MISC] Update the tree macros to a newer version. The manual, shipped for
reference, now has a more friendly 2-clause BSD license.
* various:
- [FIX] Add a missing metadata charset conversion, and add charset
conversions for filenames. From Roman Donchenko.
- [FIX] Fix build on MinGW. From Roman Donchenko.
- [MISC] Overhaul and modernize the build system. Ezstream is now expected
to build "out of the box" on more systems without configuration
tweaks.
- [FIX] Adjust the build system to better handle optional dependencies.
It is now possible to choose between TagLib and libvorbis for
reading Ogg Vorbis metadata, or no Vorbis metadata support at
all. (Ticket #1398)
- [MISC] Miscellaneous code maintenance and a bit of cleaning up.
Changes in 0.5.3, released on 2007-12-01:
* src/ezstream.c:
- [FIX] Prevent (very) long-running ezstream processes from dying without
error message by ignoring SIGPIPE where available.
Changes in 0.5.2, released on 2007-11-04:
* src/ezstream.c:
- [FIX] Fix a crash that occurs when streaming from standard input without
using a script or program that supplies metadata information.
(Ticket #1247)
- [FIX] Similar to the fix for #1247, properly initialize another
variable. The result is a cosmetic fix for the "real-time" status
line when streaming from standard input.
- [MISC] Provide a useful error message when there's no more data to read
from standard input instead of talking about scary, bad file
descriptors.
- [MISC] Further prettify the output to make more sense when streaming from
standard input.
* src/xalloc.c:
- [FIX] A rare, possible crash has been fixed in an error path.
* examples/*:
- [NEW] Add an example configuration for streaming from standard input.
- [MISC] Improve reencoding examples to make them more easily usable with
fewer changes.
- [MISC] Reenconding example files have been renamed.
Changes in 0.5.1, released on 2007-09-16:
* src/playlist.c:
- [FIX] Fix a segmentation fault in playlist_*_next() when trying to
access empty playlists. (Ticket #1240)
* src/ezstream.c:
- [MISC] Issue a warning in verbose mode when dealing with an empty
playlist file. This also makes it more obvious what is going on
when a user makes ezstream spin on an empty playlist with
<stream_once/> set to 0.
Changes in 0.5.0, released on 2007-08-31:
* src/ezstream.c:
- [FIX] The special case of streaming MP3 files without reencoding had
been lost, causing such streams to have no metadata. This has
been fixed. (Ticket #1225)
- [MISC] Handle SIGINT and SIGTERM to perform a clean shutdown.
* various:
- [NEW] A new convenience feature has been added, to allow automatic
normalization of metadata strings. Useful if the majority of
files come from a broken encoder/tagging program. Disabled
by default, this feature can be enabled with the new `-n'
command line parameter.
- [NEW] Enable Unicode support in TagLib and convert metadata strings
to the current locale (LC_CTYPE) before displaying them on the
console. Unsupported characters are displayed as '?', which
does not affect the actual metadata. This feature requires
iconv() via libc, if available, or GNU libiconv.
- [NEW] Support gettimeofday() functionality on all platforms, including
Windows. The "real-time status line" when using the -q and -v
parameters is now complete everywhere.
- [MISC] Add new --enable-debug configuration option to the configure
script, which enables (also new) memory debugging features.
(Not interesting for non-developers.)
- [MISC] Various small code cleanups.
* The Windows build of ezstream now supports reading metadata from files
with TagLib.
Changes in 0.4.3, released on 2007-07-24:
* src/ezstream.c:
- [FIX] Plug the file descriptor leak, partially fixed in version 0.4.1,
for good - it affected more than just the -q use case.
Changes in 0.4.2, released on 2007-07-17:
* src/ezstream.c:
- [FIX] Make <stream_once/> work with playlists, too. Problem found by
Geoff Shang <geoff at quitelikely dot com>.
Changes in 0.4.1, released on 2007-07-15:
* src/ezstream.c:
- [FIX] Plug a file descriptor leak when using the -q parameter.
* Documentation:
- [FIX] Minor spelling/consistency fixes.
Changes in 0.4.0, released on 2007-03-11:
* src/util.*:
- [FIX] The xfree() function did not work as intended due to a programming
error. Found, and fix suggested, by Karl Heyes.
* src/playlist.*:
- [FIX] An error compareable to the one about xfree() in src/util.* has
been fixed.
- [MISC] Refuse to execute a group- or world-writeable playlist script or
program.
* src/compat.c:
- [NEW] Implement a basename() function for Windows that behaves like the
ones used on Unix systems.
* win32/:
- [MISC] Remove the rather ugly HTML version of the man page from the
distribution, and provide a much better PDF version instead.
* various:
- [NEW] Allow ezstream to use TagLib for reading metadata from media
files. TagLib (libtag_c) is now an optional dependency.
- [NEW] When built with TagLib support, include the song length in the
"real-time" information line, if available.
- [NEW] New <metadata_progname> configuration option, which causes
metadata to be read from the output of an external program or
script.
- [NEW] New runtime control via the SIGUSR2 signal, which triggers reading
of fresh metadata information from <metadata_progname> (metadata
is always read at song changes.)
- [NEW] New <metadata_format> configuration option, to customize metadata
strings when used with the new <metadata_progname> feature.
- [NEW] New '@a@' and '@t@' placeholders for separate artist and title
metadata in de-/encoder commands.
Changes in 0.3.0, released on 2007-03-05:
* The original author, Ed Zaleski, hands over ezstream maintainership to
Moritz Grimm.
* New features:
- Playlist shuffling support, enabled via the new <shuffle> configuration
option.
- Playlist scripting support: Indicate that the executable in <filename>
should be run each time to get a new media filename to stream, by setting
the new <playlist_program> configuration option to 1.
- New <stream_once> configuration option, which makes ezstream play a media
file or playlist once and then exit.
- New <reconnect_tries> option to restrict the number of reconnection
attempts to a server in case the connection goes down.
- Add feature to skip the currently streaming track, done by sending the
SIGUSR1 signal to the ezstream process.
- New command line option `-q': Suppress standard error output from external
de-/encoders.
- New command line option `-v': Produce more verbose output.
- New "real-time" status display of the stream when both -q and -v are given
on the command line.
- Thorough configuration file checks with helpful error messages.
- The @M@ metadata placeholder is now supported in <decode>.
- Playlists may now have the '.txt' filename extension in addition to
'.m3u'.
* Fixes:
- At least one stack and one heap overflow have been fixed.
- Several memory leaks have been fixed.
- Strict checking of the configuration file prevents unexpected behavior and
adds another safeguard to prevent crashes.
- Fixed and more portable signal handling.
* Miscellaneous, user-visible changes:
- Improved documentation. Ezstream now has a comprehensive man page and the
README file has been rewritten.
- Consistency improvements in the configuration examples. The examples are
now also installed.
- The <format/> and <match/> configuration elements, as well as filename
extension matching to detect playlists in the <filename> element, are
now case insensitive.
- Various improvements in the build system and portability fixes.
- Consistent and more helpful messages from ezstream. By default, ezstream
no longer clutters the screen with lots of output (some information that
used to be available needs to be enabled with the new `-v' command line
parameter.)
- Tweaked metadata string generation: no more lone " - " dashes at the
beginning or end of the string.
- New command line option `-V': Print the version number and exit.
Changes in 0.2.1, released on 2005-12-14:
* src/ezstream.c:
- [FIX] Prevent a heap overflow with large ID3v1 tags.
- [FIX] Use pclose() on FILE* handles that were opened with popen().

Changes in 0.1.2, released on 2004-04-21:
* src/ezstream.c:
- [ADD] Add feature to reread the playlist after the currently streaming
track, done by sending the SIGHUP signal to the ezstream process.
