| 2017-11-19 | zlib: Fix race condition when closing gzip ports....Fixes <https://bugs.gnu.org/29335>.
* guix/zlib.scm (close-procedure): Remove.
(make-gzip-input-port): Do (dup (fileno port)) to get a file descriptor
for 'gzdopen'. Close PORT before returning. Use 'gzclose' as the
'close' procedure of the returned port.
(make-gzip-output-port): Likewise.

| 2017-10-11 | zlib: Fix memory leak due to revealed ports not being GC'd....Fixes <https://bugs.gnu.org/28784>.
This mostly reverts 81a0f1cdf12e7bcc34c1203f034a323fa8f52cf5, which
introduced a regression: revealed ports are *never* GC'd (contrary to
what Guile's manual suggests).
In addition to the revert, 'close-procedure' now explicitly swallows
EBADF errors when 'close-port' is called.
* guix/zlib.scm (close-procedure): New procedure.
(make-gzip-input-port)[gzfile]: Use 'fileno' instead of 'port->fdes'.
Use 'close-procedure' instead of 'gzclose'.
(make-gzip-output-port): Likewise.
* tests/zlib.scm ("compression/decompression pipe"): Use 'port-closed?'
to determine whether PARENT has been closed.

| 2017-03-15 | zlib: Don't rely on EBADF being ignored by 'fport_close'....In 2.2, 'fport_close' no longer swallows EBADF and instead raises a
'system-error' for this. This commit adjusts for 2.2.
* guix/zlib.scm (close-procedure): Remove.
(make-gzip-input-port): Use 'port->fdes' instead of 'fileno'.
Use 'gzclose' instead of 'close-procedure'.
(make-gzip-output-port): Likewise.
* tests/zlib.scm ("compression/decompression pipe"): Don't check whether
PARENT is closed using 'port-closed?'. Instead, use 'seek' on the
underlying FD and check for EBADF.

| 2016-07-27 | zlib: Protect against non-empty port internal buffers....* guix/zlib.scm (make-gzip-input-port)[gzfile]: Error out
if (drain-input port) returns a non-empty string.
* guix/zlib.scm (make-gzip-output-port)[gzfile]: Call 'force-output'.

| 2016-07-27 | zlib: Clarify when 'gzread!' can return zero....* guix/zlib.scm (gzread!): Augment docstring to clarify when zero is
returned (based on reading zlib code).
(make-gzip-input-port)[read!]: Remove scary comment.

| 2016-07-19 | Add (guix zlib)....* guix/zlib.scm, tests/zlib.scm: New files.
* Makefile.am (MODULES): Add guix/zlib.scm.
(SCM_TESTS): Add tests/zlib.scm.
* m4/guix.m4 (GUIX_LIBGCRYPT_LIBDIR): New macro.
* configure.ac (LIBGCRYPT_LIBDIR): Use it. Define and substitute
'LIBZ'.
* guix/config.scm.in (%libz): New variable.
