VDR 1.5.15 on Gentoo: random and silent crash at startup
by Ville Aakko 30 Mar '08

30 Mar '08

Hi! Since VDR 1.5.10 (or thereabouts) VDR has had this weird problem - and now that the 1.6 RC is near, I decided to report it (also I've been a bit busy so I wouldn't had had the time to look into this before myself). VDR dies at startup randomly, at around 5 seconds after the startup (the Gentoo init script detects this fail, and so watchdog is newer started). Just as randomly (~50% of the times) it start without errors and is stable (as rock) in my working environment =). When it crashes, I can sometimes see the "Welcome to VDR" in my VFD, sometimes even on the output of my DXR3 (if not always but I don't have my TV turned on always), but right at that point the gentoo-vdr-scripts decide they have waited enough. This could be a gentoo-vdr-scripts bug, too. btw., this is what I run in my root crontab to work around this: ---- START VDRpurkkakoira.sh ---- #!/bin/bash while true ; do /etc/init.d/vdr start if [ $? -gt 0 ] ; then ### punch the VDR sleep 5s else sleep 30m fi done ---- END ---- This also works as an additional layer of a watchdog; hence the script name =) Usually it needs 1-5 punches (but sometimes none). I believe some plugin is to blame. At VDR upgrade (when no plugin is loaded as they usually need a recompile) VDR has never died this way. I have my suspicions but I'm not going to tell them before I do some more testing, to not to upset developers for nothing =) Here are my plugins: dxr3 femon osdteletext mplayer undelete streamdev-server lcdproc control externalplayer epgsearchonly text2skin epgsearch quickepgsearch burn So, I'm going to do some testing by disabling plugins, but in the meantime, has anyone run into the same problem? Or does anyone have any suggestions I should try? Also, I'll provide the syslog of my VDR in case someone is interested - though it didn't provide anything to me that would tell why it fails (and why it doesn't, when it doesn't). - Ville -- Ville Aakko - ville.aakko(a)gmail.com

Missing EPG entry @ MTV3 now!
by Ville Aakko 29 Mar '08

29 Mar '08

Hello VDR users, Is there a bug in VDR or is there a fault in the EPG data sent by MTV3? There is no Abyss in the EPG on my VDR box, even though it most certainly should be there, 22..25-01.05 EET (sat-sun). Is this a DST bug? I haven't noticed any errors on other channels. I'm using VDR 1.6.0 on Gentoo. -- Ville Aakko - ville.aakko(a)gmail.com

[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);
