[Announce] vdr-fritzbox-0.0.13
by Joachim Wilke 29 Mar '08

29 Mar '08

Dear Fritz!Box- and VDR-Users, a new version of the Fritz!Box Plugin is available at http://joachim-wilke.de/index.htm?alias=vdr-fritz If no serious bugs appear with this release, it will get the stable plugin release 1.0.0 for VDR 1.6. Translation contributions (.po-files) are appreciated. - - - The Fritz!Box Plugin connects to your Fritz!Box to inform you about incoming calls. The plugin can automatically mute or pause VDR when a call comes in. Via VDR's main menu you can browse your Fritz!Box phone book, the call lists and initiate calls out of all lists. - - - 2008-03-30: Version 0.0.13 - updated french translations (provided by Patrice [10]) - fixed wrong dsyslog output in fritzlistener.c - fixed outputting the '#96*5*5'-hint - fixed an uninitialized socket variable in cTcpClient that caused closing sockets not created by the plugin (e.g., cKbdRemote socket) - updated russian translations (provided by neptunvasja [6]) - fixed translating the plugin description - moved call to cFritzTools::GetPhoneSettings() out of cPluginFritzbox::Initialize() to avoid blocking the main thread - cFritzTools::GetPhoneSettings() handles missing OKZ/LKZ settings in Fritz!Box correctly. If no LKZ is set, 49 is assumed. - extended cFritzListener to handle multiple lines in one message - corrected some dsyslog() calls missing the sourcecode filename - - - Regards, Joachim.

[PATCH] Direct I/O support v1
by Artur Skawina 27 Mar '08

27 Mar '08

This change makes vdr write the video stream directly to disk, bypassing OS caches. O_DIRECT is used if it is supported, falling back to "normal" I/O and fadvise() if not. Only recording is affected, playback remains unchanged. I did this to see if using direct i/o made sense for vdr, wasn't convinced before. Avoiding all the fadvise hacks and especially the fdatasyncs on close seems to be worth it though. Only lightly tested, but seems to work, i tried a few recordings on both ext3 and NFS and didn't notice any missing data yet ;) Upgraded all vdrs and will keep testing for some time, but in case anyone else would like to try (or even better improve) it, patch is below. This patch is based on top of the one I posted in the "Problems playing ongoing recordings?" thread, so you'll need to apply that one before applying this one. Should work on both 1.4 and 1.6. artur diff --git a/tools.c b/tools.c index a14f799..b7281b0 100644 --- a/tools.c +++ b/tools.c @@ -1054,6 +1054,11 @@ bool cSafeFile::Close(void) // --- cUnbufferedFile ------------------------------------------------------- #define USE_FADVISE +#define USE_DIRECTIO + +// O_DIRECT can have various alignment restrictions, usually at most +// the block size of the filesystem. 4096 bytes should be enough. +#define ALIGN_DIO 4096 //#define dfsyslog dsyslog // uncomment to turn on fadvise related logging #define dfsyslog(a...) do {} while (0) @@ -1071,7 +1076,17 @@ cUnbufferedFile::~cUnbufferedFile() int cUnbufferedFile::Open(const char *FileName, int Flags, mode_t Mode) { Close(); - fd = open(FileName, Flags, Mode); +#ifdef USE_DIRECTIO + if (Flags&(O_WRONLY|O_RDWR)) { + fd = open(FileName, Flags|O_DIRECT, Mode); + directio = 1; + } +#endif + if (fd==-1) { + directio = 0; + fd = open(FileName, Flags, Mode); + } + dsyslog("Using %s IO to access %s", directio?"DIRECT":"normal", FileName); curpos = 0; #ifdef USE_FADVISE lastpos = 0; @@ -1101,7 +1116,7 @@ int cUnbufferedFile::Close(void) free(wbuf); } #ifdef USE_FADVISE - if (fd >= 0) { + if (fd >= 0 || !directio) { if (totwritten) // if we wrote anything make sure the data has hit the disk before fdatasync(fd); // calling fadvise, as this is our last chance to un-cache it. posix_fadvise(fd, 0, 0, POSIX_FADV_DONTNEED); @@ -1243,7 +1258,36 @@ ssize_t cUnbufferedFile::Read(void *Data, size_t Size) ssize_t cUnbufferedFile::WriteBuf(const void *Data, size_t Size) { if (fd >=0) { - ssize_t bytesWritten = safe_write(fd, Data, Size); + ssize_t bytesWritten; + +#ifdef USE_DIRECTIO + if (directio) { + // write properly sized buffers directly. + if ((Size & (ALIGN_DIO-1)) == 0) { + bytesWritten = safe_write(fd, Data, Size); + curpos += bytesWritten; + return bytesWritten; + } + // in the unlikely case of a short write (inevitable when closing) + // pad the data with zeros, write it, then truncate the file. + int padding = ALIGN_DIO - (Size & (ALIGN_DIO-1)); + memset((char *)Data+Size, 0, padding); + bytesWritten = safe_write(fd, Data, Size+padding); + + padding = bytesWritten - Size; + if (padding<0) + padding = 0; + bytesWritten -= padding; + curpos += bytesWritten; + + lseek(fd, -padding, SEEK_CUR); + ftruncate(fd, curpos); + // note: past this point the file offset is likely unaligned + // so further directio shouldn't happen. + return min(bytesWritten, (ssize_t)Size); + } +#endif + bytesWritten = safe_write(fd, Data, Size); //dsyslog("WRIT: fd:%3d %9zd .. %9zd SIZE: %6zd", fd, curpos, curpos+Size, Size); #ifdef USE_FADVISE if (bytesWritten > 0) { @@ -1296,18 +1340,23 @@ ssize_t cUnbufferedFile::Write(const void *Data, size_t Size) { if (!wbuf) { wbuf_chunk = cutting?MEGABYTE(8):MEGABYTE(4); - wbuf = MALLOC(uchar,wbuf_chunk); - if (!wbuf) + if (posix_memalign(&wbuf, ALIGN_DIO, wbuf_chunk)) { + directio = 0; return WriteBuf(Data, Size); + } wbuf_len = 0; } if (Size <= wbuf_chunk-wbuf_len) { memcpy(wbuf+wbuf_len, Data, Size); wbuf_len += Size; } else { - WriteBuf(wbuf, wbuf_len); - memcpy(wbuf, Data, Size); - wbuf_len = Size; + unsigned l = wbuf_chunk-wbuf_len; + if (l) + memcpy(wbuf+wbuf_len, Data, l); + WriteBuf(wbuf, wbuf_chunk); + + memcpy(wbuf, (char *)Data+l, Size-l); + wbuf_len = Size-l; } return Size; } diff --git a/tools.h b/tools.h index ce7283c..c2ff493 100644 --- a/tools.h +++ b/tools.h @@ -255,6 +255,7 @@ private: size_t written; size_t totwritten; int cutting; + int directio; size_t writebuffer; int FadviseDrop(off_t Offset, off_t Len); int FadviseRead(off_t Offset, off_t Len);

vdr 1.6.0
by Tony Grant 27 Mar '08

27 Mar '08

OK I now have the following set up: - hush with VIA Epia M10000 - Fedora Core 8 up to date except libX11* - xine-lib 1.2 from hg today 27/03/2008 - vdr 1.6.0 - vdr-xine 0.8.2 - femon 1.2.4 - vdradmin-am-3.6.1 *In order to use xine with xxmc hardware acceleration I have downgraded libX11 to the version from Fedora Core 7 - bug libX11 with xcb support xine still locks up if I change desktops to check my mail or if I try to use the right click configuration menu when running with vdr. Fine when running xine with other media files. I am now able to use pulseaudio in xine - recent updates of alsa and pulseaudio probably fixed the issues I was having. Sound can still be crappy when watching an avi file... Cheers Tony --

Reinhard, I decided to try vdr 1.6.0 and vdr-xine 0.8.2 and have ran into the XINE VDR VERSION MISMATCH in INSTALL issue. I am running xine-lib 1.2 pulled from the xine site pkg-config --cflags libxine -I/usr/local/include I can't see what is wrong Cheers Tony --
