2019-01-02splice: fix missing F_NONBLOCK flag for single output
This fixes hanging when using a single audio output for Linux users using splice.
2019-01-02dtas 0.16.0 v0.16.0
A bunch of minor fixes and cleanups accumulating for the past two years since the last release. It's tough to remember to make releases when I'm always running the latest version from git :x Most notably, "io_splice" is no longer used for dtas-linux users since "sleepy_penguin" includes all the functionality we use. This is to reduce memory overhead from extra DSOs(*) There's also some deprecation warning fixes for the still-undocumented "dtas-mlib" command. 12 changes since v0.15.0 (2017-04-07): pipeline: new module for running process pipelines console: ensure time calculations are done in UTC Rakefile: update path for uploads player: support guessing encodings for comments get rid of Windows-31J regexps mlib: compatibility with Sequel 5.x mlib: remove redundant tag massaging and encoding mlib: use flock to get around SQLite busy errors mlib: ignore files with nil times dtas/watchable: check SystemCallError mlib: fix unused variable warning use sleepy_penguin 3.5+ for splice and tee support (*) https://udrepper.livejournal.com/8790.html
2019-01-02use sleepy_penguin 3.5+ for splice and tee support
Eliminate loading of the io_splice RubyGem to reduce memory overhead. Extra DSOs are wasteful and io_splice is being phased oiut for sleepy_penguin, which encapsulates more Linux-specific functionality anyways. cf. https://udrepper.livejournal.com/8790.html
2017-01-02buffer/splice: remove MAX_SIZE constant
We do not need it at runtime, only for testing on Linux-like systems
2016-12-27http -> https, and relocate homepage to https://80x24.org/dtas/
HTTPS allows some level of security(*) and we've actually supported it on 80x24.org for many months, now. So, point new readers to it. Moving away from hostname-based homepages will allow us to save on subjectAltName space (and bandwith) when negotiating an HTTPS connection. We'll also have an .onion mirror for Tor users, soon, too; in case we can't afford to pay ICANN in the future. (assuming TLS libraries don't have any more Heartblead-level bugs in them, CAs aren't compromised, MITM HTTPS stripping proxies don't get in your way, and your certificate bundle isn't compromised).
2016-01-02copyright updates for 2016
Using the 'update-copyright' script from gnulib[1]: git ls-files | UPDATE_COPYRIGHT_HOLDER='all contributors' \ UPDATE_COPYRIGHT_USE_INTERVALS=2 \ xargs /path/to/gnulib/build-aux/update-copyright [1] git://git.savannah.gnu.org/gnulib.git
2015-12-25enable "frozen_string_literal: true"
While we're in the area, make a wording change from "GPLv3 or later" to "GPL-3.0+", as the latter is favored by SPDX.org
2015-09-06use a common /dev/null
This allows us to avoid wasting time reopening the same device over and over again.
2015-02-04buffer: allow limiting the amount of bytes output tfx-pu
This will aid in allowing us to create effects which affect only a certain part of a track.
2015-02-04buffer/splice: prepare for IO::Splice::WAITALL removal
This feature in the io_splice was probably a bad idea and slated for removal at some point in the future. Anyways, do not rely on it since it is undocumented.
2015-01-20doc: describe most classes a bit
Hopefully this makes the code less daunting to newcomers
2015-01-19update copyright years and links to mailing list archives
The documentation part is managed by the new Documentation/update-copyright script. For the future, the rest may be managed by the update-copyright tool in gnulib
2014-06-06update copyrights and email address for 2014
I'm still normal, and still trolling, but 80x24.org will be epic :)
2013-12-27merge some select calls for splice users
Avoid an additional select syscall in the splice path by injecting the target checks into the main loop. We can do this because we always process writers before readers. This adds additional userspace processing, but it avoids one potentially expensive (and potentially task-switching) syscall in many cases; so it should be worth it to avoid skipping with small buffer. This should avoid buffer underuns with mixed-sized buffers when using multiple sinks. This could work for the read_write path, too, but I don't use that enough and this change may still be buggy even for splice users.
2013-12-27buffer/splice: favor &:method for blocks
This is slightly easier-to-read and avoids capturing local variables.
2013-10-12IO#nread compatibility for Rubinius (Linux-only)
We don't deal with user-space buffers, so we should be fine using this compatibility layer and only checking the kernel buffers (until rbx implements a proper solution).
2013-10-06buffer: remove ioctl syscall in common paths
We do not need this for single sink situations (the common case) at all. We also do not need to check IO#nread for splice, either; we can just do non-blocking I/O. The only common path where we might still need it is the non-splice case with multiple sinks.
2013-08-29remove "encoding: binary" header use
We don't need it since IO#read(bytes, buf) will convert to ASCII-8BIT anyways. Everywhere else, we ensure path names are already binary. We do this mainly at the client layer before using Shellwords to escape the paths. We also must be careful about parsing output from soxi/avprobe which can show us metadata in whatever encoding is in the file. We must still handle data from parsing command output as binary, as the encoding of file metadata tends to vary. This also should buy us Syck compatibility for Ruby 1.9.3 users on Debian systems where Ruby 1.9.3 still uses Syck.
2013-08-28add license/copyright headers/footers to all files
All files we distribute in the tarball need to have a copyright/license specified for Savannah. We don't need the example state file anymore.
2013-08-25more cleanups for packaging and documentation v0.0.0
Rename COPYRIGHT -> COPYING, as that seems to be the more common name for the GPLv3 license file. Kill all rdoc, since I don't agree with HTML documentation and we do not expose any Ruby APIs.
