zlib: Fix race condition when closing gzip ports.

2017-11-19T22:09:01Z

Fixes . * 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.

zlib: Fix memory leak due to revealed ports not being GC'd.

Fixes . 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.

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.

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'.

zlib: Clarify when 'gzread!' can return zero.

2016-07-27T10:45:01Z

* 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.

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.
