libfixposix's Introduction

The purpose of libfixposix is to offer replacements for parts of POSIX whose behaviour is inconsistent across *NIX flavours.

Compilation

If you've downloaded this library through git, you'll first need to generate the ./configure script; in order to do that you need to have at least autoconf-2.67, automake-1.10, libtool-2.2.6b, pkg-config and check (for the test suite: see http://check.sf.net) then run this inside the top directory:

autoreconf -i -f

For best results use a dedicated build directory instead of running the configure script directly in the source tree:

mkdir build ; cd build ../libfixposix/configure make make install

On Linux, you might need to run «ldconfig» as superuser after installing, otherwise the *nix linker won't be able to find the library

Installation through distro repositories

For a certain number of Linux distributions, there are officially supported repositories. You can find the instructions to configure the binary repository at https://software.opensuse.org/download.html?project=home:sionescu&package=libfixposix. Just click on your distribution, if present.

http://article.gmane.org/gmane.lisp.iolib.devel/422 also has a set of older instructions about installing on Debian-based distros.

libfixposix's Issues

Fails to build in DragonFlyBSD

I was trying to compile LFP for JRuby/Ruby SubSpawn on DragonFlyBSD, but it errored out.

The only issue is that sys/termios.h isn't present, in favor of just termios.h.

Modifying

libfixposix/configure.ac

Line 84 in 16f524a

LFP_REQUIRE_DECL([TIOCSCTTY], [sys/ioctl.h sys/termios.h])

to remove the sys/ prefix on termios.h, I can compile on DFBSD, but this obviously isn't the correct solution.

Incorrect use of ^ operator

I don't think this is right:

    tp->tv_sec  = attributes[0] / 10^9;
    tp->tv_nsec = attributes[0] % 10^9;

10^9 equals 3, not 1000000000

bitset.h is missing from the release (v0.4.0) tarball

Not sure if you're aware, but the release tarball is missing bitset.h, which causes build failure:

how to generate the libfixposix.so file

hi, Sionescu
As my title, how can I generate the libfixposix.so file ? configure --enable-shared will not work.

Sorry, I find it already.

Termux install

I'm trying to install it on Termux, but my experience with C is little to none.

I need to install it so that I can use another of your libraries iolib.

Here's the output I'm getting:

Add rlimit lfp_spawn attribute

See jruby/jruby#6552.

MacOSX runtime error with memory allocations

This patch is still needed to be able to use libfixposix on MacOSX. Can it be included as is, or do you think more work is required?

Investigate using setgroups()

A lint check in OBS gives this message:

W: missing-call-to-setgroups-before-setuid /usr/lib64/libfixposix.so.3.0.0
This executable is calling setuid and setgid without setgroups or initgroups.
There is a high probability this means it didn't relinquish all groups, and
this would be a potential security issue to be fixed. Seek POS36-C on the web
for details about the problem.

I get error

Debian package "libfixposix0" does not work with iolib

I used "apt-get install libfixposix-dev" on debian 8 to install libfixposix, and then I used quicklisp to install CLWS (websockets library) which depends on iolib. However, trying to run a websockets server crashed somewhere in iolib with an "unhandled memory fault".

Cloning the git repo for libfixposix and installing it manually fixed the problem. This is pretty easy to do, so perhaps you could put a note in the README for iolib that if problems arise with the debian package, building and installing it manually may help.

configure error on CentOS 5.8 Final 64bit

cd libfixposix-master
./configure --prefix=/usr/local

Error message here:

./configure: line 12195: syntax error near unexpected token `CHECK,'
./configure: line 12195: `    PKG_CHECK_MODULES(CHECK, check >= 0.9.4)'

Note: I compiled and installed check v0.10.0(because CentOS 5 is too old that yum only installed check-devel-0.9.3-5.fc6):

cd check-0.10.0
./configure --prefix=/usr/local
make && sudo make install

without any Error.

Note2: autoreconf -i -f without any Error.

Use clone() to spawn the new process in lfp_spawn()

Details in https://blog.famzah.net/2009/11/20/a-much-faster-popen-and-system-implementation-for-linux/

Add lfp_spawn() attribute to set the terminal process group

See https://twitter.com/ridiculous_fish/status/1232889396107431937 and https://www.mail-archive.com/[email protected]/msg00718.html.

packaging clarification

Stelian,

could you please add either an INSTALL file or extend the README with some words on how to install the packaged version and what is its status in the main distributions?

as far as i understand lfp reached the repos of the main distros, but there's only and old (2011) version in those repos. your repo (http://download.opensuse.org/repositories/home:/sionescu/Ubuntu_Trusty/) seems to have 0.3.0 which seems to be newer. BTW, this repo is also not mentioned in the README.

if you can squeeze in the time needed then a short update of the README could greatly simplify the users' lives.

thanks for your work!

lfp3 debian 8 package broken?

i just installed lfp from

deb http://download.opensuse.org/repositories/home:/sionescu/Debian_8/ ./

and this is the file list in the libfixposix3 package:

/.
/usr
/usr/share
/usr/share/doc
/usr/share/doc/libfixposix3
/usr/share/doc/libfixposix3/README.md
/usr/share/doc/libfixposix3/changelog.gz
/usr/share/doc/libfixposix3/copyright

i.e. the .so is not included? (the error that made me to look was that
the .so was not found by SBCL)

is it something i do, or the package is indeed broken?

Add umask lfp_spawn attribute
