I sometimes look at a piece of software and if the man page says
"Copyright 2004", then I'm inclined to think that the project is stale
or that the authors are lazy. Neither is good publicity for us :-)
There is no need to use entropy here just to create some content that only will
be used for hashing and ignored.
This avoids a problem where dd from /dev/urandom on solaris generates too short
output.
This greatly speeds up node->rev lookups, with results that are
often user-perceptible: for instance, "hg --time log" of the node
associated with rev 1000 on a linux-2.6 repo improves from 0.3
seconds to 0.03. I have not found any instances of slowdowns.
The new perfnodelookup command in contrib/perf.py demonstrates the
speedup more dramatically, since it performs no I/O. For a single
lookup, the new code is about 40x faster.
These changes also prepare the ground for the possibility of further
improving the performance of prefix-based node lookups.
test-hup hangs on AIX. Under ksh89 on AIX (the default shell),
echo Hello; while [ ! -s not-there ]; do true; done
produces no output while the loop executes. Replacing 'true' with 'sleep 0'
fixes, as does using a less broken shell. ksh93 is fine.
Update check-code.py to look for this, and make same change in test-serve.t.
In fact test-serve works fine, probably because of additional commands between
echo and the loop, but that's a subtlety not easy to test for.
This patch contains support for Plan 9 from Bell Labs. A README is
provided in contrib/plan9 which describes the port in greater detail.
A new extension is also provided named factotum which permits the
factotum(4) authentication agent to provide credentials for HTTP
repositories. This extension is also applicable to other POSIX
platforms which make use of Plan 9 from User Space (aka plan9ports).
printf on AIX default shell ksh (89) says \1 is an invalid escape. It insists
on at least 2 digits. This causes failures in test-keyword.t and test-status.t.
check-code.py already looks out for \NNN and recommends using Python
for outputting octal values. Extend the check to \NN and \N and fix up
resulting failures.
The Mercurial ssh protocol is defined as if it was ssh-ing to a shell account on
an ordinary ssh server, and where hg was available in $PATH and it executed
the command "hg -R REPOPATH serve --stdio".
The Mercurial ssh client can in most cases just pass REPOPATH to the shell, but
if it contains unsafe characters the client will have to quote it so the shell
will pass the right -R value to hg. Correct quoting of repopaths was introduced
in 7bec00a7d7a6 and tweaked in c3194121de6c.
hg-ssh doesn't create the command via a shell and used a simple parser instead.
It worked fine for simple paths without any quoting, but if any kind of quoting
was used it failed to parse the command like the shell would do it.
This makes hg-ssh behave more like a normal shell with hg in the path would do.
