Hi,
Note that one significant change to read.dcf() that happened since R
3.0.2 is the addition of support for arbitrary long lines (commit
63281), which never worked:
dcf <- paste(c("aa: ", rep(letters, length.out=10000)), collapse="")
writeLines(dcf, "test.dcf")

write.dcf/read.dcf cycle converts missing entry to "NA" (PR#9796)
Full_Name: Bill Dunlap
Version: 2.5.0
OS: Red Hat Enterprise Linux WS release 3 (Taroon Update 6)
Submission from: (NULL) (24.17.60.30)
If you read a dcf file with read.dcf(file,fields=c("Field",...))
and the file does not contain the desired field "Field",
read.dcf puts a character NA for that entry in its output
matrix. If you then call write.dcf, passing it the output
of read.dcf(), it will write the entry "Field: NA&quo...

Lack of final newline in write.dcf changes append usage
The change in r42731 eliminating the final blank line when writing DCF
files changes the way 'append' can be used in 'write.dcf' and I was
wondering if this is intentional. Basically, I want to write a data
frame to DCF format one row at a time, so I make use of repeated calls
to 'write.dcf(append = TRUE)'. However, in R 2.6.0RC the resulting...

write.dcf does not quote as Debian would like it to (PR#12816)
...The Debian Policy Manual says concerning lines in a Description field:
* Those containing a space, a full stop and some more characters. These are for
future expansion. Do not use them.
(section 5.6.13, http://www.debian.org/doc/debian-policy/ch-controlfields.html)
But for example:
> write.dcf(list(Description = 'there was a fat goat .haha'),indent=1,width=10)
Description:
there
was a
fat goat
.haha
A simple quoting scheme is to add a space in front of such full stops:

Bug in read.dcf(all = TRUE)?
Hi,
read.dcf() can modify the locale variable LC_CTYPE, and here is a
minimal example:

[1] "en_US.UTF-8"
> read.dcf(textConnection('a: b'), all = TRUE)
a
1 b
> Sys.getlocale('LC_CTYPE')
[1] "C"

segfault with readDCF on R 3.1.2 on AIX 6.1 when using install.packages
Here's an update:
I checked the ChangeLog for R, and it seems like readDCF was changed
in 3.0.2. I went on a whim and copied src/main/dcf.c from R 2.15.3
over to 3.2.2, and R compiled fine and install.packages now work for
me.
This is probably not ideal, but it at least makes R usable on AIX for
me. Would definitely like to help figure out what's wrong with the

Read.dcf with no newline ending: gzfile drops last line
I don't know if this is a bug per se, but an undesired behavior in
read.dcf. read.dcf takes a file argument and passes it to gzfile if
it's a character:
if (is.character(file)) {
file <- gzfile(file)
on.exit(close(file))
}
This gzfile connection is passed to readLines (line #39):
lines <- readLines(file)
If no newline is at the end of th...

tools:: extracting pkg dependencies from DCF
...ols package is better place, for such a fundamental
functionality, than community packages.
tools pkg seems perfect fit (having already great function write_PACKAGES).
Functionality I am asking for is already in R svn repository since 2016, in
a branch tools4pkgs. Function is called 'packages.dcf'.
Another one 'repos.dcf' would be a good functional complementary to it.
Those two simple helper functions really makes it easier for organizations
to glue together usage of their own R packages repos and CRAN repo in a
smooth way. That could possibly help to offload CRAN from new sub...

segfault on write.dcf with gzfile connection
I'm seeing a segfault on x86_64 Linux with the following code:
desc = read.dcf("BAD")
con = gzfile("test.gz", "wt")
write.dcf(desc, file=con)
close(con)
where BAD has a long field (see below for example). The crash happens
inside dummy_vfprintf. I think the issue is that the va_list ap is
