system2 doesn't quote stdin on unix, unlike stdout, stderr & input and on Windows
Hi again! While investigating the bug report [*] I found out that on unix, system2 does not quote its `stdin` argument while preparing the command line to launch. It does shQuote the `stdout` and `stderr` arguments, and also the `f <- tmpfile()` variable (which is used if `input` argument is provided), which seems to set a precedent. On Windows, stdin, stdout, and stderr are handled independently of t...

[RFC] [tools] Changing Behavior of LLVM binutils When No File Is Specified
Some binutils, nm comes to mind, when to input file is specified will default to a.out. Others do not do this and read from stdin by default. The rest of this email will be specifically referencing these which read from stdin, and not the tools which for various reasons do things differently. I propose that we change the behavior of these tools to use a.out when appropriate. By appropriate I mean firstly, no input file speci...

readLines function with R >= 3.5.0
Hi: I have also just stumbled into this bug. Unfortunately, I can not change the data my program receives from stdin. My code runs in a larger system and stdin is sent to a Docker container running my R code. The protocol is I read a line, readLines("stdin", n=1), do some actions, send output on stdout, and wait for the next set of data. I don't have control over this protocol, so I can't use t...

Asterisk 1.4.30 is slow sending STDIN to AGI script
...() returned error: Broken pipe I have tracked it down to a perl AGI script which performs our own CDR recording. It is called before the start of the call, once answered and again when the call is hungup. It works fine when called before dialing and the AGI debugging shows asterisk sending the STDIN to the script very fast. When called after answering and at the end of the call asterisk is much slower sending the STDIN and I can see the debug scrolling up the screen and this is what is causing the error as the AGI script finished and exits before all the STDIN is sent. Even if I add a paus...

[RFC] [tools] Changing Behavior of LLVM binutils When No File Is Specified
...m-objdump defaulting to a.out, but llvm-readelf giving this warning message. My guess is that moving away from using a.out by default for llvm-objdump, llvm-nm and others whose gnu counter parts do this would be more disruptive than my proposal. As Jake pointed out we use "-" to describe stdin/stdout, GNU's tools do not do this, so I think there is some precedence for us slightly modifying behavior when we can reasonably say things will not happen, like the file "-" existing.

server: Fix reading passwords interactively.
https://bugzilla.redhat.com/show_bug.cgi?id=1842440 Patches 1 and 2 address fairly obvious bugs in how we handle reading passwords from stdin. There are other ways we may consider fixing these bugs: - Should password=- always open /dev/tty and ignore stdin entirely? - Should we make password=-0/-1/-2 work by skipping the close? Or perhaps reopen the file descriptors on /dev/null after reading the password? (This seems over-c...

[nbdkit PATCH v2 2/3] server: Sanitize stdin/out before running plugin code
As shown in the previous patch, plugins may choose to use stdin or stdout during .config. But from .get_ready onwards, well-written plugins shouldn't be needing any further use of stdin/out. We already swapped stdin/out to /dev/null while daemonizing, but did not do do during -f or --run, which leads to some surprising inconsistency when trying to debug a...

Bug 17432 in readLines with R >= 3.5.0 still a problem
Bug 17432 (https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=17432) is still a problem when using pipes for IPC. The bug is evident when calling R from another process and trying to communicate via StdIn. R will buffer the input and not read lines until the buffer is exceeded or StdIn is closed by the sending process. This prevents interactive communication between a calling process and a child R process. >From a quick look at the source code, it looks like the bug is caused by only disabling...

ices2 + stdin + metadata
Hi, does anybody know some info about posting metadata to ices2 via stdin? My system is based on a PHP-script wich sends PCM-data from the player (mpg123 or ogg123) over a pipe to ices2. As i understand the documentation, metadata is sent as normal clear text within the PCM-data when using stdin. I tried the following format: \n artist=foo\n title=bar\n (\n is, of cours...
