I just noticed some droppings on my disk from what must be a pretty weird
|
||
|
|
bug in remote CVS.
|
||
|
|
|
||
|
|
In my home directory on a repository machine I use, I find:
|
||
|

|
||
|

|

|
|

|
|
OK, so these are leftover cruft from some cvs run that got aborted.
|
||
|
|
Well, it should clean up after itself, but so what.
|
||
|
|
|
||
|
|
The last one is pretty dull; the real weirdness is the contents of the
|
||
|
|
first two directories.

Subject: Problem with rtag and the -D option
|
||
|
|
Date: Fri, 17 Mar 1995 10:53:29 -0600 (CST)
|
||
|
|
|
||
|
|
I have been trying to use the -D option to specify a date for tagging, but
|
||
|
|
rtag does not recognize the -D option. It is documented to do so and I've
|
||
|
|
tested the use of -D with cvs update and cvs diff and it works fine there.
|
||
|
|
|
||
|
|
|
||
|
|
* We need some version numbers really badly. Are there some
|
||
|
|
(and Charles Hannum is just not including them in his reports), or do
|
||
|
|
we simply have no reliable way to distinguish between the various
|
||
|
|
versions of rCVS people on the list are running?
|
||
|
|
|
||
|
|
Now that I think of it, version numbers present a problem when
|
||
|
|
people can update their sources anytime and rebuild. I think the
|
||
|
|
solution is to increment a minor version number *every* time a bug is
|
||
|
|
fixed, so we can identify uniquely what someone is running when they
|
||
|
|
submit a report. This implies recording the version increments in the
|
||
|
|
ChangeLog; that way we can just look to see where a particular version
|
||
|
|
lies in relation to the flow of changing code.
|
||
|
|
|
||
|
|
Should we be doing same with Guppy? I guess not -- it's only
|
||
|
|
important when you have people who are updating directly from your
|
||
|
|
development tree, which is the case with the remote-cvs folks.
|
||
|
|
|
||
|
|
Thoughts?

* (Charles Hannum <mycroft@ai.mit.edu>) has these bugs:
|
||
|
|
|
||
|
|
I just tossed remote CVS at a fairly large source tree that I already
|
||
|
|
had, and noticed a few problems:
|
||
|
|
|
||
|
|
1) server.c assumes that /usr/tmp is a valid default for the place to
|
||
|
|
store files uploaded from the client. There are a number of systems
|
||
|
|
that now use /var/tmp. These should probably be detected by autoconf.
|
||
|
|
|
||
|
|
2) The server deals rather ungracefully with the tmp directory
|
||
|
|
becoming full.
|
||
|
|
|
||
|
|
3) There's some oddness with relative paths in Repository files that
|
||
|
|
causes the directory prefix to be added twice; e.g. if I have CVSROOT
|
||
|
|
set to `machine:/this/dir', and I try to update in a directory whose
|
||
|
|
Repository file says `src/bin', the server looks in
|
||
|
|
`/this/dir/machine:/this/dir/src/bin'.

Subject: Serious flaw in remote CVS

|
|
Date: Wed, 22 Feb 1995 20:54:36 -0500
|
||
|
|
|
||
|
|
I just found a major flaw in the current implementation. Because the
|
||
|
|
sockets are not changed to non-blocking mode, write(2)s can hang. In
|
||
|
|
some cases, this happens on both sides at the same time, with the
|
||
|
|
socket buffers full in both directions. This causes a deadlock,
|
||
|
|
because both processes are stuck in I/O wait and thus never drain
|
||
|
|
their input queues.
|
||
|
|
|
||
|
|
Until this is fixed, I can't use it. I'll look at the problem myself
|
||
|
|
at some point, but I don't know when.

FYI, this happened because the tmp directory on the server became
|
||
|
|
full. Somehow the server started interpreting the files the client
|
||
|
|
was sending as commands, and started spewing tons of errors.
|
||
|
|
Apparently the errors are sent with blocking I/O, or something, and
|
||
|
|
thus allowed the deadlock to happen.

This is actually more serious. If you have `bar.com:/foo' as your CVS
|
||
|
|
root directory, then:
|
||
|
|
|
||
|
|
1) When you check things out, the Repository files will contain
|
||
|
|
`/foo/...' (i.e. without the machine name), which makes little sense.
|
||
|
|
|
||
|
|
2) If you instead have a relative path, when the Repository file is
|
||
|
|
read, `bar.com:/foo' is prepended. This is sent to the server, but
|
||
|
|
confuses it, because it's not expecting the machine name to be
|
||
|
|
prepended.
|
||
|
|
|
||
|
|
A slightly klugy fix would be to have the client prepend the machine
|
||
|
|
name when writing a new Repository file, and strip it off before
|
||
|
|
sending one to the server. This would be backward-compatible with the
|
||
|
|
current arrangement.

This is pretty weird:

CVS_SERVER='TMPDIR=. /usr/local/bin/cvs' ../cvs-build/src/cvs update -q
|

#define ERANGE 34 /* Result too large */
|
||

|
|

|
|
Now, getcwd fails with ERANGE when the buffer is too small. But I don't
|
||
|
|
know why that would be the case; I don't think there are exceptionally long
|
||
|
|
directory names involved. It would be robust to notice ERANGE and use a

|
bigger buffer. But I suspect something weirder is going on.
