This is an implementation of syslog with some OpenBSD extensions.
There is no syslogd support (so it only logs to dbgprintf/stderr),
but otherwise is functional.
Many weird defines are always present, because some syslog users in
the wild check for their existence.
Serenity is really not production ready; I shouldn't have to warn
you not to trust the RNG here. This is for compatibility with
software expecting the interface.
arc4random does expose an annoying flaw with the syscall I want
to discuss with Kling though.
These are basically copy and pasted from the regular string version.
Also add some more multi-byte/wide conversion stub.
libarchive wanted these. There's a lot more, but we can add them
one at a time.
Seems POSIX is odd and unistd also defines SEEK_SET if stdio.h
This simply follows the pattern several other C libraries take of setting
these macros to the same values in stdio if that header is not included.
Made getsockopt() and setsockopt() virtual so we can handle them in the
various Socket subclasses. The subclasses map kinda nicely to "levels".
This will allow us to implement things like "traceroute", although..
I spent some time trying to do that, but then hit a wall when it turned
out that the user-mode networking in QEMU doesn't preserve TTL in the
ICMP packets passing through.
The fchdir() function is equivalent to chdir() except that the
directory that is to be the new current working directory is
specified by a file descriptor.
MAXPATHLEN defines the longest permissable path length after expanding
symbolic links. It is used to allocate a temporary buffer from the buffer
pool in which to do the name expansion, hence should be a power of two.
On UNIX MAXPATHLEN has the same size as PATH_MAX.
After some very confused debugging, I discovered that GNU make has a
main() function with this signature:
int main(int argc, char** argv, char** envp)
Apparently this is a non-standard but widely supported thing, so let's
do the same in Serenity so make works as expected.
This fixes an issue where you had to do "make PATH=..." instead of make
just picking up PATH from the environment. :^)
Now that the kernel supports thread-local storage, we can declare errno
with the __thread keyword, which causes it to be per-thread.
This should fix all the stupid issues that happen when many threads use
the same errno. :^)
We were already borrowing a getopt() from the BSD family until the day
we write our own. This patch borrows a slightly more modern one so we
also get getopt_long().
Fixes#190.
See also #91 for the desire to eventually NIH our own getopt()..
This was a workaround to be able to build on case-insensitive file
systems where it might get confused about <string.h> vs <String.h>.
Let's just not support building that way, so String.h can have an
objectively nicer name. :^)
Rewrite this function to go from left-to-right instead of right-to-left
since this allows us to accumulate valid characters before encountering
any invalid ones.
This fixes parsing of strings emitted by GCC, like "1, %0|%0, %1}". :^)
