Fixes from Jimmy Olgeni. Fixes from Hans Ulrich Niedermann. 3.2.3: ------ Fix bug when invoking with no arguments. 3.2.2: ------ Move throughput measuring end to after close(2). 3.2.1: ------ print throughput after fsync, if requested. 3.2.0: ------ -O F option (do an fsync at the end of the output file). When closing files fails, exit with an error code. 3.1.1: ------ -n was not clear to use numbers > 2 GB. I didn't notice since it worked fine if you used suffixes "K/M/G" as long as the number was < 2 G. Sorry about that. 3.1.0: ------ O_DIRECT supported for input. 3.0.0: ------ IPV6 support for IPV6 day 2011. The IPV6 support shouldn't break anything after hostname lookup succeeds. Issues might be building on older platforms if I screwed up the autoconf mechanism to not compile it in. Having said that, assorted little code cleanups are in this release, too. They shouldn't break anything but non-IPV6 things were touched. Aftermath for 2.7.4 - 2.7.6: ---------------------------- ATTENTION: I'm afraid that support for the '-B ' was clobbered in 2.7.4 or whereabouts. This one allowed you do have a reader do multiple reads before the writer could write or vice versa. Change reverted in 2.7.6. 2.7.4 and 2.7.5 do not have working -B. 2.8.0: ------ Support platforms that do not have open(2) with O_DIRECT. Such as MacOS X. 2.7.6: ------ Revert 2.7.3 which broke -B 2.7.5: ------ NetBSD and general pkgsrc compatibility. Should get rid of the only patch used in pkgsrc. 2.7.4: ------ Print the message that we switch to normal from O_DIRECT only when verbose > 0. SEE ABOVE, broke -B. CHANGE reverted 2.7.3: ------ More c flags changes for more portability. 2.7.2: ------ Fix compilation under Redhat-7.3. 2.7.1: ------ Support for $CSTREAM_AUDIO_BITRATE. 2.7.0: ------ Support for O_SYNC and O_DIRECT, but only on the output side for now. Please send mail if you want this for input. 2.6.1: ------ Timer-based throughput reports from -T will now also print what the throughput since the last report was. Useful when performance changes during runtime. 2.6.0: ------ Bandwidth limiting was not > 4 GB clean on platforms with 32 bit integers. I had lost an already existing fix here. 2.5.2: ------ Commandline options, options to -O and -I: -ON -IN which prevents cstream from interpreting filenames with ":" in them as TCP specifications. By default the presense of a colon means host:port. 2.5.1: ------ Add option -T which will print the statistics every seconds. 2.5: ---- There was a 4 GB limitation on 32 bit machines when you used bandwith limiting. Thanks to Sergey M. Serov for reporting! 2.4.1b: ------- Use SO_REUSEADDR on serving socket. 2.4: ---- Bandwidth limiting is not not only as a strict maximum at any point in time but now you can also limit for the session as a whole. Do so by giving a negative bandwidth limit. To make it clear: if the session was running below the limit for some time for other bottlenecks in the chain, then it will run above the limit to make good for it at other times when it can. 2.3: ---- Identical to 2.3b3, sigchld handling is assumed to be correct now and works with various versions of the Linux kernel. Version 2.3 has sound support, see e.g. `cstream -Oa -o /dev/dsp`. 2.3b3: ------ Further SIGCHLD fixes. 2.3b2: ------ Fix SIGCHLD handling so that stopping and continuing the child in a concurrent mode would not terminate. 2.3b1: ------ Version 2.3 has sound support, see e.g. `cstream -Oa -o /dev/dsp` version 2.2: ------------ TCP/IP socket support. Linux glibc 64 bit files. Version 2.1: ------------ - Add audio mode: -O a/-I a try to switch output file into CD-quality 16bit 44100Hz stereo mode. If input is just generated, a sine wave of 440 Hz will be played. - Add tee-fd mode. -O t will copy the stream to file descriptor 3 (which must already be opened by parent process). Version 2.0: ------------ - Add -c flag for concurrent mode. - Add -B flag (buffering of multiple input blocks before output blocks are written). - Add -l flag (statistics will include line count). - If input data is just 'generated', use a buffer that remotely resembles ASCII text with a line length of 76 chars and has a newline at the end of data. - Number of bytes transferred is also displayed in GB/MB/KB, if appriopriate. - Change throughput report to be shorter. - Add automatic tests `make check`. - Througput reporting on signals got the wrong time when cstream was not called with -v > 0. - Use SIGINFO for throughput report. - Use more values from configure script. - Throughput report is now asynchronous, not after next read() or write(). - Throughput report will report buffer fillage if -B is in use. Version 1.4: ------------ - Fix Linux compilation problems. - The -b and -t options now also recognize 'k', 'm', 'g' for kilo-, mega-, gigabyte like the -n option did. - The signal for shutdown is now SIGUSR2, not SIGHUP. Version 1.3: ------------ - Fix permissions of created files - You can now specify the input file without using a switch (if it is the last argument) - Improve messages Version 1.2: ------------ - Argument checking for -v was broken, fixed. Version 1.1: ------------ - Fix version number reporting, introduce -V switch. - Fix usage() typos. Version 1.0: ------------ - Initial version. cstream-4.0.0/tests/000755 000765 000024 00000000000 14354371124 015247 5ustar00cracauerstaff000000 000000 cstream-4.0.0/INSTALLATION000644 000765 000024 00000000465 07236041724 015737 0ustar00cracauerstaff000000 000000 cstream follows the usual GNU configure building process: ./configure --prefix=/usr/local make make install The following compile-time options are supported: ------------------------------------------------- --enable-notcp Leave out TCP/IP socket code --enable-nosound Leave out audio control code cstream-4.0.0/cstream.c000644 000765 000024 00000136454 14354370772 015734 0ustar00cracauerstaff000000 000000 /* * Copyright 1998, 1999, 2000, 2001 Martin Cracauer * * See the file COPYRIGHT in the distribution package for copying terms. */ #ifndef HAVE_STRUCT_ITIMERVAL #error no itimerval #define NOTIMER #endif #define WITH_RESOLV /* * Control glibc, especially to get 64 bit file offsets */ #ifdef __linux /* * Don't use this unless I have to: * #define _GNU_SOURCE */ /* * Let me see if I get that straight: * -first enable "some" additional calls */ #define _LARGEFILE_SOURCE /* * -then enable the 64 bits variants of traditional calls, on seperate names */ #define _LARGEFILE64_SOURCE /* * and now make the 64 bit variants shadow the old calls */ #define _FILE_OFFSET_BITS 64 #endif #include #include #include #include #include #include #if HAVE_UNISTD_H || CRAENV #include #endif #include #if TIME_WITH_SYS_TIME || CRAENV #include #include #else /* TIME_WITH_SYS_TIME */ #if HAVE_SYS_TIME_H #include #else #include #endif #endif /* TIME_WITH_SYS_TIME */ #include #include #ifdef HAVE_WINSOCK2_H #include #endif #ifdef __linux #define __USE_GNU #endif #include #include #ifdef HAVE_SYS_UIO_H #include #endif #include #if HAVE_SYS_WAIT_H || CRAENV #include #endif #if HAVE_POLL_H #include #ifndef POLLRDNORM #define POLLRDNORM 0 #endif #ifndef POLLWRNORM #define POLLWRNORM 0 #endif #ifndef INFTIM #define INFTIM -1 #endif #endif /* HAVE_POLL_H */ #ifdef HAVE_SYS_STATVFS_H #include #endif #ifndef NOSOUND #ifdef HAVE_MACHINE_SOUNDCARD_H #include #define WANT_SOUND 1 #else #ifdef HAVE_SYS_SOUNDCARD_H #include #define WANT_SOUND 1 #else #ifdef HAVE_LINUX_SOUNDCARD_H #include #define WANT_SOUND 1 #include #endif /* linux/soundcard.h */ #endif /* either soundcard.h */ #endif /* either soundcard.h */ #endif /* ndef NOSOUND */ #ifndef HAVE_SYS_SOCKET_H #define NOTCP #endif #ifdef NOTCP #define NORESOLV 1 #endif #ifndef NOTCP #ifdef HAVE_SYS_SOCKET_H #include #endif #ifdef HAVE_NETINET_IN_H #include #endif #ifdef HAVE_ARPA_INET_H #include #endif #ifndef HAVE_NETDB_H #define NORESOLV #endif /* Solaris needs this */ #ifndef INADDR_NONE #define INADDR_NONE 0xffffffff #endif #ifndef NORESOLV #include #endif #if !defined(HAVE_SOCKLEN_T) && !defined(NORESOLV) typedef u_int32_t socklen_t; #endif #ifndef INADDR_NONE #define INADDR_NONE -1 #endif #endif /* NOTCP */ #ifdef O_SYNC # define MY_O_SYNC O_SYNC #else # ifdef O_FSYNC # define MY_O_SYNC O_FSYNC # endif #endif #ifdef HAVE_LIBJACK #include #endif volatile sig_atomic_t stopit; volatile sig_atomic_t signal_report; volatile sig_atomic_t n_sighups; volatile sig_atomic_t childpid = 0; int pagesize = -1; struct pmalloc { void *data; void *allocated; size_t n_bytes; }; struct options { int v; long long n; int t; char *i; char *o; char *I; char *O; char *p; int l; int B; int c; int w; int S; int T; int user_specified_blocksize; int six; }; void malloc_page_aligned(const struct options *o, struct pmalloc * pmalloc); struct progstate { int b; /* Blocksize, to be changed to separate input and output sizes */ int ifd; int ofd; long long bytes_transferred; /* How many bytes transferred so far */ int bytes_firsttransfer; /* How many bytes were transferred at the * first read/write pair?

Featues: Sane commandline switch syntax. Exact throughput limiting, on the incoming side. Timing variance in previous reads are counterbalanced in the following reads. Precise throughput reporting. Either at the end of the transmission or everytime SIGUSR1 is received. Quite useful to ask lengthy opertions how much data has been transferred yet, i.e. when writing tapes. Reports are done in bytes/sec and if appropriate in KB/sec or MB/sec, where 1K = 1024. SIGUSR2 causes a clean shutdown before EOF on input, timing informating is displayed. Build-in support to write its PID to a file, for painless sending of these signals. Build-in support for fifos. Example usage is a 'pseudo-device', something that sinks or delivers data at an appropriate rate, but looks like a file, i.e. if you test soundcard software. See the manpage for examples. Built-in data creation and sink, no more redirection of /dev/null and /dev/zero. These special devices speed varies greatly amoung operating systems, redirecting from it isn't appropriate benchmarking and a waste of resources anyway. Accepts 'k', 'm' and 'g' character after number for "kilo, mega, giga" bytes for overall data size limit. "gcc -Wall" clean source code, serious effort taken to avoid undefined behaviour in ANSI C or POSIX, except long long is required. Limiting and reporting works on data amounts > 4 GB. cstream was written by Martin Cracauer in 1998.

"Since first transfer" should also exclude the last write (or at least the close, important on tapes). Support -B option to set blocksize for writes, if not already set by -b, which will continue to set both unless -B has been used before. In concurrent mode, who is going to report what? Parent is easier handling-wise, but it cannot report output throughput without having an upward pipe. But we may need such a pipe soon anyway. Don't use the required blocksize for the pipe in concurrent mode. This can easily be done if read and write block size are specified seperately and then just set obs in the parent and ibs in the child to a useful value (maybe even to be specified by the user, cause it's a space vs. number of syscalls tradeoff).

It has a more traditional commandline syntax, support for precise bandwidth limiting and reporting and support for FIFOs. Data limits and throughput rate calculation will work for files > 4 GB. .Pp .Nm Cstream reads from the standard input and writes to the standard output, if no filenames are given. It will also 'generate' or 'sink' data if desired. .Pp Options: .Bl -tag -width "-l num " .It Fl b Ar num Set the block size used for read/write to .Ar num . The default is 8192 bytes. .It Fl B Ar num Buffer input up to .Ar num bytes before writing. The default is the blocksize. It is an error to set this to anything below the blocksize. Useful when writing tapes and similar that prefer few large writes of many small. .It Fl c Ar num Concurrent operation. Use a separate process for output. This is especially useful in combination with the -B option. .Bl -tag -compact -width " " .It 0 = use one process only (default) .It 1 = read process will buffer .It 2 = write process will buffer .It 3 = both processes will buffer. In combination with a large buffer size this will often load your memory heavily, every time the reader transfers the buffer it collected to the writer. If you use -c 3 and have a buffer size of 128 Megabytes 256 MB of memory will be touched at once. .El .It Fl i Ar num .It Fl o Ar num Set the file names to use for input or output, respectively. If the output file name is "-", data will just be discarded. If the input file name is "-", data will be generated 'out of the void'. If these options aren't given, stdin/stout will be used. If you need to give .Fl o or .Fl i options and want stdin/stdout, specify the empty string, like this: .Pp cstream -i'' .Pp If TCP support has been compiled in (default), hostname:portnumber will try to connect to the specified host at the specified port and :portnumber will open a TCP socket on the local machine and wait for a connection to arrive. SECURITY NOTE: cstream includes no mechanism to restrict the hosts that may connect to this port. Unless your machine has other network filters, anyone will be able to connect. .It Fl I Ar string .It Fl O Ar string Specify the type of input and output file, respectively. .Bl -tag -compact -width " " .It If string includes 'f', a fifo will be created. .It If string includes 'F', a rsync(2) will be issued before closing the output file. .It If string includes 'a', the file will be assumed to be a opensound-compatible audio device and will be switched to CD-like settings. .It If string includes 't', a copy of the stream will be sent to file descriptor 3. .It If string includes 'N', TCP will not be used for that file even if the name has a ":". .El .It Fl l Include line count in statistics. .It Fl n Ar num Limit the total amount of data to .Ar num . If there is more input available, it will be discarded, .Nm cstream will exit after the limit has been reached. If there is less input, the limit will not be reached and no error will be signaled. .Pp .Ar num may have a trailing 'k', 'm' or 'g' which means Kilobytes, Megabytes or Gigabytes (where Kilo = 1024). This applies to all numeric options. .It Fl p Ar filename Write the process id of cstream to .Ar filename . If cstream uses a separate writer process (option -c), this is the pid of the parent (reader) process. .It Fl t Ar num Limit the throughput of the data stream to .Ar num bytes/second. Limiting is done at the input side, you can rely on cstream not accepting more than this rate. If the number you give is positive, cstream accumulates errors and tries to keep the overall rate at the specified value, for the whole session. If you give a negative number, it is an upper limit for each read/write system call pair. In other words: the negative number will never exceed that limit, the positive number will exceed it to make good for previous underutilization. .It Fl T Ar num Report throughput every num seconds. .It Fl v Ar num Set verbose level to .Ar num . By default, it is set to 0, which means no messages are displayed as long as no errors occur. A value of 1 means that total amount of data and throughput will be displayed at the end of program run. A value of 2 means the transfer rate since the end of the first read/write pair will also be reported (useful when there is an initial delay). A value of 3 means there will also be separate measurements for read and write. This option is resource-consuming and currently isn't implemented. A value of 4 means that notices about each single read/write will be displayed. High values include all message types of lower values. .It Fl V Print version number to stdout and exit with 0. .It Ar filename A single filename as the last argument without an option switch will be used as input file if -i has not been used. .It Ic SIGUSR1 .It Ic SIGINFO Sending SIGUSR1 (or SIGINFO, which is usually mapped to Control-T on you keyboard) to cstream causes it to display throughput rates to stderr. The stream will continue as if nothing happened. .It Ic SIGUSR2 Exit and report throughput rates, if requested. .It Ic SIGHUP I found myself sending SIGHUP accidentally too often. But ignoring or misusing SIGHUP is not an option for me. Thus, when .Nm cstream received SIGHUP, it will wait 5 seconds for another SIGHUP, to give users a chance to correct a possible mistake. If no additional SIGHUP is received, .Nm cstream kills itself with SIGHUP. .El .Sh EXAMPLES .Bl -tag -width indent .It Ic "cstream -o tmpfile -v 1 -n 384m -i -" Writes 384 Megabytes of unspecified data to file .Pa tmpfile and display verbose throughput rate. Makes a good benchmark, the speed of .Pa /dev/null varies too much from system to system. .It Ic "cstream -i tmpfile -v 1 -n 384m -o -" Read the same file back in and discard data. .It Ic "cstream -b 2000 -t 10000 /var/log/messages" Will display the file in a more or less watchable speed. .It Ic "dump 0sf 400000 - / | cstream -v 1 -b 32768 -o /dev/rst0 -p pidfile" .It Ic kill \-USR1 `cat pidfile` Write the output from dump(1) to tape. Each time the signal is sent, the throughput and data rate so far will be displayed. .It Ic "cstream -t 176400 -i /dev/dsp0 -I f -o -" Makes kind of a soundcard emulator which may be used to test audio applications that need something to write to that limits the data rate as a real soundcard does. This obviously doesn't work when the application tries to write data using mmap(2) and the application has to ignore errors when it tries to set soundcard parameters using ioctl(2). .It Ic "cstream -t 176400 -i /dev/dsp0 -I f -o /dev/dsp1 -O f" Similar soundcard emulator, except that it allows you to grab the data your applications sends to it from the other fifo, while still having precise timing. .It Ic "cstream -Oa -o /dev/dsp0 myhost.mydomain.com:17324" Connects port 3333 on host myhost.mydomain.com and whatever data it finds there will be sent to the soundcard, with appropriate settings for CD quality stereo play. .It Ic "cstream -i myaudiofile.raw -o :17324" This will open a TCP server on port 17324 and waits until someone connects (for example, the commandline from the previous example). Then it will send the contents of myaudiofile.raw down the TCP stream (for the previous audio example, typically a CD audio track like you get from the tosha or cdparanoia utilities). .It Ic "cstream -OD -o myfile" Write to file myfile with O_DIRECT. That usually means that the filesystem buffer cache will not try to cache this file. You can use that to prevent copying operations from eating up physical memory. Note that when cstream encounters a write error it will switch the output file from O_DIRECT to a normal file and write all further blocks without O_DIRECT if writes without O_DIRECT succeed. In practice that usually means that your last block, if not a multiple of the filesystem block size, will still be written into the file (the maximum amount of data written without O_DIRECT is your blocksize minus one). That way cstream ensures that the output file has the length of the input, however odd the length was and no matter what restrictions your OS places on O_DIRECT output. Again, cstream will *not* pad the output to the block size, you get the same file and file size as if not using O_DIRECT, at the cost of switching to non-O_DIRECT whenever a block is not the right size. .It Ic cstream -i :3333 | dd obs=8192 | ./cstream -omyfile -v7 -OD This is what you need to do to buffer TCP input, so that the last cstream will not switch away from O_DIRECT prematurely because of short reads. If your input can do short reads (e.g. from TCP), and you want to ensure that O_DIRECT stays in effect, you need a buffer between the TCP stream and the O_DIRECT stream. Since cstream does not yet support different input and output block sizes, dd is suitable here. Note that this is only necessary if the OS requires multiples of the filesystem block size for O_DIRECT. At the time of this writing this construct is needed on Linux for using TCP streams with O_DIRECT, but it is not needed on FreeBSD. .It Ic "cstream -OS -o myfile" Writes to file myfile with O_SYNC. This means by the time the system call returns the data is known to be on disk. This is not the same thing as O_DIRECT. O_DIRECT can do its own buffering, with O_SYNC there is no buffering at all. At the time of this writing, O_SYNC on both Linux and FreeBSD is very slow (1/5th to 1/10th of normal write) and O_DIRECT is reasonably fast (1/4th to 1/2 of normal write). You can combined O_SYNC and O_DIRECT. .El .Sh ERRORS .Bl -tag -width "-l num " .It Exit code 0 means success. .It Exit code 1 means a commandline syntax usage error. .It Exit code 2 means other errors, especially system errors. .El .Sh Bugs There should be an option to begin writing directly after the first read ended and then fill the buffer with reads in the background. Right now writing will not begin before the reader has filled the buffer completely for the first time. .Pp Not a bug: the code to do O_DIRECT is reasonably sophisticated. It will fall back to normal I/O on errors. But before doing that it knows about both filesystem blocksize requirements (will default I/O blocksize to whatever the filesystem of the output file is in) and page alignment requirements (I/O will happen from a page-aligned buffer). However, the combination of concurrent read/writes (-c options) and O_DIRECT has not been tested beyond basic verification that it gets some tests right. .Sh SEE ALSO .Xr dd 1 , .Xr mkfifo 2 .Sh HISTORY .Nm cstream was initially written by Martin Cracauer in 1998.

In other projects, it is set to # '$srcdir', '$srcdir/..', or '$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.
