libpipeline 1.5.7 (13 November 2022)
====================================
* Add notes to libpipeline(3) of when functions were added.
* Transferred Git repository to https://gitlab.com/libpipeline/libpipeline.
* Make `socketpair` tests used by `./configure --enable-socketpair-pipe`
compatible with C23.
libpipeline 1.5.6 (24 April 2022)
=================================
* Fix handling of leading whitespace in `pipecmd_new_argstr` and
`pipecmd_argstr`.
libpipeline 1.5.5 (3 January 2022)
==================================
* Move release process to GitLab CI.
libpipeline 1.5.4 (7 November 2021)
===================================
* Move Git repository to GitLab (https://gitlab.com/cjwatson/libpipeline).
* Building libpipeline now requires Autoconf >= 2.64.
libpipeline 1.5.3 (13 August 2020)
==================================
* Fix implementation-defined behaviour while handling read/write errors.
* Port tests to the modern Check API.
libpipeline 1.5.2 (1 January 2020)
==================================
* `pipecmd_exec` now calls `_exit` rather than `exit`, to avoid bugs such
as functions registered using `atexit` being called multiple times.
* Document that standard FDs must be open before calling `pipeline_start`.
libpipeline 1.5.1 (27 January 2019)
===================================
* Building libpipeline now requires Autoconf >= 2.63 and Automake >=
1.11.2.
* Various portability improvements, via Gnulib.
libpipeline 1.5.0 (14 November 2017)
====================================
* Add `pipecmd_pre_exec` to install a pre-exec handler for a single
command.
libpipeline 1.4.2 (10 July 2017)
================================
* Fix EOF detection in `get_line`.
libpipeline 1.4.1 (17 August 2015)
==================================
* Fix test failure with Check 0.10.0.
libpipeline 1.4.0 (25 October 2014)
===================================
* Various portability fixes for Solaris, mostly suggested by Peter Bray.
This includes a `PIPELINE_QUIET` environment variable which suppresses
the error message normally emitted when a subprocess is terminated by a
signal.
* Add `pipecmd_fchdir`, which is analogous to `pipecmd_chdir` but takes an
open file descriptor rather than a path.
libpipeline 1.3.1 (22 September 2014)
=====================================
* Fix test failures on Cygwin.
* Fix build on systems with neither `setenv` nor `clearenv`, e.g. Solaris
8.
libpipeline 1.3.0 (26 March 2014)
=================================
* Add `pipecmd_chdir` to run a command with a different working directory.
libpipeline 1.2.6 (18 December 2013)
====================================
* Fix `test_pump_tee` to wait for its child processes before testing their
output, since otherwise not all their output might be flushed.
libpipeline 1.2.5 (3 December 2013)
===================================
* `pipeline_want_infile` and `pipeline_want_outfile` now take copies of
their file name arguments.
* Restore compatibility with Automake 1.10.
* Build with large file support on systems where it is available.
libpipeline 1.2.4 (6 June 2013)
===============================
* Provide a replacement `clearenv` function in order to support non-glibc
systems. Now tested on FreeBSD.
libpipeline 1.2.3 (24 April 2013)
=================================
* Don't read uninitialised memory when testing for the end of long lines
(over 4096 bytes).
* Flush stdio before starting a sequence.
libpipeline 1.2.2 (17 September 2012)
=====================================
* Make `pipeline_start` flush stdio after emitting debugging output.
* Build fixes for glibc 2.16 and Automake 1.12.
libpipeline 1.2.1 (2 March 2012)
================================
* Retry reads and writes on `EINTR`.
* Fix opening of output files requested by `pipeline_want_outfile`; these
are now created if they do not already exist, and truncated if they do.
* `<pipeline.h>` is now wrapped in `extern "C"` when used in a C++
compilation unit.
libpipeline 1.2.0 (18 March 2011)
=================================
* Add `pipeline_get_pid` to get the process ID of a command in a started
pipeline.
libpipeline 1.1.0 (11 December 2010)
====================================
* Add `pipecmd_exec` to execute a single command, replacing the current
process; this is analogous to `execvp`.
* Add `pipecmd_clearenv` to clear a command's environment; this is
analogous to `clearenv`.
* Add `pipecmd_get_nargs` to get the number of arguments to a command.
libpipeline 1.0.0 (29 October 2010)
===================================
This is a new C library for pipeline manipulation, broken out from man-db
2.5.8.
