documentation outputs. Apparently they were the predecessors of
setup-net.xml and cygwin-ug-net.xml. I don't know if for a time there
were parallel versions of the manuals and one fork died, or if the cutover
was clean and the old versions were just never removed. Either way,
they're dead junk now.
printed it.
- Removed obsolete utils.sgml
- Added a ChangeLog entry for this replacement, which partially took
place days ago. This checkin formalizes the switch from SGML to
DocBook XML for this file.
INFINITE amount of time. Instead default to 1/10 second.
(fhandler_pty_slave::open): Just default to INFINITE wait rather than
(now) waiting longer than previously.
include. You can't mix the two fragment inclusion mechanisms within
a single document because of the way it interacts with autoconf "build
in separate tree" mechanism. Either work separately, but they fail when
you try to use them together due to the way doctool chooses output
directories for its generated files.

handling. Move comment closer to code it is commenting on.
effect is to move away from DocBook SGML and DJ Delorie's doctool and
toward pure DocBook XSL. (There remains just one use of doctool, and
we have plans for replacing it, too.) See ChangeLog for details.

sig_dispatch_pending to flush signal queue when we can finally do something
with signals.
* exceptions.cc (sigpacket::process): Avoid attempting to handle signals if we
haven't finished initializing. Rely on the fact that find_tls will do mask
checking and don't do it again. Delete ill-named 'dummy' variable.

setting retry whenever this function is called.
(sig_send): Reorganize to wait for SIGHOLD at bottom. Always add signal to
pending queue and work on whole queue rather than just the one signal. Loop
when sigq.retry is set. Fix long-broken check for SIGCHLD after queued
signals.
follow Linux.
* fhandler_socket.cc: Change UNIX_PATH_LEN to UNIX_PATH_MAX throughout.
(fhandler_socket::recv_internal): Don't return prematurely in case of
successful return. For AF_LOCAL sockets, overwrite returned AF_INET
name with AF_LOCAL name.
filename length to allow non-NUL terminated strings within namelen
bytes. Copy over sun_path to local array sun_path to have a
NUL-terminated string for subsequent function calls. Move path_conv
check before OS bind call to not bind the socket before being sure
the file doesn't exist. Add and fix comments.
