0adb99b9dc don't pprint the IO timeout message if we are a server or daemon (can 
cause recursive error messages)

f0359dd00d went back to non-blokcing IO 
it looks like ssh is willing to accept a non-blocking fd when used as
a transport, this seems to avoid the Solaris socketpair bug

8b35435f7c another hang-at-end fix. It looks like we are more sensiitive to 
these with socketpairs. The receiver now sleeps until it gets a signal
to tell it to exit

also fixed test.sh to use the current version remotely

6d7b6081ac damn! 
the last pre-release had a bug that didn't setup the multiplexing
correctly. This means that pre-release will get "unexpected tag -7"
whenm talking to the fixed code.

ff41a59f58 - switched on multiplexing for all connections, not just daemon 
connections (this fixes the stderr/stdout problem). Upped
  protocol version for backward compat
- use multiplexing on error fd
- upped minimal protocol version
- got rid of some ugly code in the write buffering

08f15335b5 switch to using socketpair instead of pipe if possible. This fixes the 
ssh clag problems as long as you also fix the same problem in sshd

removed all the old read buffering code from io.c as this was only
there to try to reduce the chance of clagging up sshd.

cbce490e13 reinstated the MAX_READ_BUFFER code. Its a nasty tradeoff - using lots 
of memory vs. ssh bugs. uggh.

8a5d6bba09 don't use stderr after we become a daemon 2000-01-24 09:19:44 +00:00
Andrew Tridgell
554e0a8dd0 added some really ugly code to allow errors to propogate to 
clients when writing to a rsync server

it works like this:

- we have an extra pipe from the receiver to the generator
- the server always runs with multiplexing on
- errors from the generator go down the multiplexed connection
- errors from the receiver go over the pipe, and from there to
  the multiplexed conn

it required some incredibly ugly code. damn.

07b7c86c06 don't write more than PIPE_BUF bytes in any one write() in io.c 
this makes sure that the write never blocks.

1f5c6343e6 removed old non-blocking fd code (a hangover from a earlier version of 
io.c). Thanks to Theo for pointing out this brokenness.

37f9805dab changed strlcat() and strlcpy() to have the same semantics as the 
OpenBSD functions of the same name.

changed slprintf() to take buffer length rather than buffer length -1

1b7c47cb55 Jason told me that's its very important for his site to log exactly 
how many bytes were needed to be transferred for each file. I added %b
and %c log format options to cover this. See the man page for details.

d730b113f4 final change needed to get rsync working on a CRAY J90 1998-10-29 05:48:11 +00:00
Andrew Tridgell
8de330a387 changes to get rsync working on a CRAY J90. This machine doesn't have 
a 4 byte integer type (short is 8 bytes). I needed to use a new md4
implementation (I used the portable one I wrote for Samba).

6e4fb64e61 added finddead target, removed dead code and made some functions

2f9af90118 removed the limit on the read buffer size until I fully understand the 
interactions with ssh. The old ssh freezes have shown up again and
some debugging (with help from James Welborn) showed that the cause
was the read buffer hitting maximum size. I think this means that ssh
must be misbehaving about blocking IO.

This change gets rid of the freezes at the expense of memory
usage. Where it would have frozen it uses more memory instead.

c46ded4621 I think I might havefinally fixed the rsync hanging bug. It was caused 
by a read during an io_flush() triggered during a readfd(). A simple
logic bug in the io code :(

8cd9fd4e8c always use a timeout to select, even if --timeout is not 
specified. This makes things easier to debug.

ssh-friendly attempt)

bf9f01689f if we get EWOULDBLOCK on a write then reduce the amount of data we are 
trying to write. This guarantees that the maximum amount of data that
can be written at any one time is written.

f7b9377863 handle non-blocking file descriptors for both read and write. Add a 
workaround for buggy systems that say there is space to write when
there isn't.

e44f9a12c4 make sure that io_flush() doesn't call writefd_unbuffered from within 
a writefd_unbuffered call!

this should fix the "decompressor lost sync" bug

- handle start of line in exclude properly

4c36ddbeec heaps of cleanup in the io code. 
we no longer use non-blocking IO, instead it uses select a lot more,
being careful to always allow for reading whenever a valid read fd is
available and chcking timeouts.

also split the file io calls into fileio.c

679e765768 fixed a multiplexing bug 1998-05-18 10:23:47 +00:00
Andrew Tridgell
8d9dc9f99d this is a large commit which adds io multiplexing, thus giving error 
messages from the server when using the socket code.

I've doen a fair bit of testing and I don't seem to have broken
anything, but it is a very complex change. More testing needed!

5dd7e03167 put a limit (default 1MB) on the read buffer size. This stops it 
growing too much if the sender is much faster than the receiver

e42c9458c2 use strlcat() strlcpy() and slprintf() whenever possible to avoid any

f0fca04e4e first vesrion of working socket based rsync. It still needs a lot of

9486289ce4 some large systematic changes to make socket conversion easier. The
