Here's the Exec rewrite patch that compiles on WIN32 too. With a
fake NUL (link to /dev/null) it even passed the test suite. :-)
Sat Sep 9 07:52:04 CEST 2006 Eric Kow <[EMAIL PROTECTED]>
* Fix Windows stderr non-redirection.
(It was consistently redirecting to stdout.)
Also make the exec code more readable/transparent.
Mon Sep 11 12:29:33 CEST 2006 Tommy Pettersson <[EMAIL PROTECTED]>
* rewrite Exec.lhs, new exec interface with Redirects
Make the code structure a bit simpler and easier to understand.
Only one (fancy) version of exec.
Mon Sep 11 12:32:16 CEST 2006 Tommy Pettersson <[EMAIL PROTECTED]>
* update all usages of exec (and exec_fancy) to new interface

Redirection of stdin and stdout breaks putty, which uses these to
interact with the user. Quiet mode, and redirecting stderr are good
enough for making ssh silent.

[overhaul the darcs.net front page.
Mark Stosberg <[EMAIL PROTECTED]>**20060820191415
The themes to this change are:
- Focus on the key benefits of darcs:
Distributed. Interactive. Smart.
- Recognize that the wiki is the central resource,
and remove some information that is duplicated here
and reference the wik instead.
I can post a demo of this HTML for easy comparison if you'd like.

[Reimplement --disable-ssh-cm flag (issue239).
Eric Kow <[EMAIL PROTECTED]>**20060812134856
My patch to "Only launch SSH control master on demand" accidentally
removed the ability to disable use of SSH ControlMaster. Also, the
way it was implemented is not compatible with launching on demand.
This implementation relies on a notion of global variables using
unsafe IORefs.

Eric Kow <[EMAIL PROTECTED]>**20060812121943]
[Rename AtExit module to Global.
Eric Kow <[EMAIL PROTECTED]>**20060812121925
The goal is to capture some broad "global" notions like exit handlers
and global variables. Note the GPL header thrown in for good measure.

[Fix issue 185: don't combine AddFile and RmFile in the same patch
[EMAIL PROTECTED]
For unknown reason (a possibly previous version of) darcs allows a
single patch to Add and Remove the same file in a single patch. The
"changes" command used to combine them, showing just a Remove. This
prevents combining those two events and shows two distinct actions.

[Read sftp batch file in from stdin (part of issue237).
Eric Kow <[EMAIL PROTECTED]>**20060812143113
Passing the batch file in from stdin allows for sftp to be used with
password-based authentication. According to the sftp user manual regarding
the -b switch:
Since it lacks user interaction it should be
used in conjunction with non-interactive authentication
Credit for this idea goes to Ori Avtalion.

[fix negation of result in test
Tommy Pettersson <[EMAIL PROTECTED]>**20060806104215
Negation with ! "uses" the result and thus there is no "failure", so the

- Add exec_ function, which does the same thing as exec,
but allows redirection on stderr, and also allows us
to NOT redirect stdin/stderr

no need to deal with the details of launching or exiting the control
master.
