This is implemented by folding up every branch of depth 2 or more,

then not dealing with them, plausibly leading to a loop. Works for me,

it'll let you see an identifier (SHGFP_TYPE_CURRENT) referenced since r7082.

Morally, this should be defined for all toolchains, not just MinGW/Cygwin, but I'll leave that to people who have those toolchains.

takes a third argument which is TRUE if the file is being opened for
writing and wants to be created in such a way that it's readable
only to the owner. This is used when saving private keys.
While I'm here, I also use this option when writing session logs, on
the general principle that they probably contain _something_
sensitive.
The new argument is only supported on Unix, for the moment. (I think
writing owner-accessible-only files is the default on Windows.)

Application Data directory in preference to the old-fashioned
attempt to find the user's home directory, and use the _local-
machine_ Application Data directory in preference even to that.
SHGetFolderPath() is called via GetProcAddress, so this degrades
gracefully on old Windowses. (Tested myself on Win95.)
As part of this change, we now search for a location for the seed
file separately for reading and writing, so that installing the new
PuTTY should cause a seamless migration as the old seed file is read
from the old location and then a new one written to the new location.
`putty -cleanup' attempts to delete the seed file from _all_
affected locations.
Naturally, a user-specified seed file path in the Registry still
takes priority over all other means of finding the location.

caused by the MessageBox() internal message loop eating WinSock
FD_READ notifications, which then don't reappear afterwards because
you have to explicitly prod a socket in order to get a repeat
notification on it.
Hence, here's a piece of infrastructure which seems to sort it out:
a new winnet.c function called socket_reselect_all(), whose function
is to go through all currently active sockets and re-run
WSAAsyncSelect() on them, causing repeat notifications for anything
we might have missed. I call this after every call to MessageBox(),
and that seems to solve the problem.
(The problem was actually masked in very recent revisions, probably
by the reinstatement of pending_netevent in r7071. However, I don't
believe that was a complete fix. This should be.)

suite. In a dramatic break with tradition, I'm actually checking in
the resulting icon files as well as the script that generates them,
because the script requires Python and ImageMagick and I don't think
it's reasonable to require that much extra infrastructure on
everyone checking out from Subversion.
The new icons should be _almost_ indistinguishable from the old
ones, at least at the 32x32 resolution. The immediately visible
change is that all the icons now come in 16x16, 32x32 and 48x48
formats, in both 16 colours and monochrome, instead of an ad-hoc
mixture of whichever ones I could be bothered to draw.
The same code can also be adapted to generate icons for the GTK port
(although icons for the running programs don't seem to be supported
by GTK 1 - another reason to upgrade to GTK 2!).

and various calls to WinHelp() have been centralised into a new file
winhelp.c, which in turn has been modified to detect a .CHM file as
well as .HLP and select between them as appropriate. It explicitly
tries to load HHCTRL.OCX and use GetProcAddress, meaning that it
_should_ still work correctly on pre-HTML-Help platforms, falling
gracefully back to WinHelp, but although I tested this by
temporarily renaming my own HHCTRL.OCX I haven't yet been able to
test it on a real HTML-Help-free platform.
Also in this checkin: a new .but file and docs makefile changes to
make it convenient to build the sources for a .CHM. As yet, owing to
limitations of Halibut's CHM support, I'm not able to write a .CHM
directly, more's the pity.

easily manage, by adopting a hybrid approach to Unicode text
display. The old approach of simply calling ExtTextOutW provided
font linking without us having to lift a finger, but didn't do the
right thing when it came to bidirectional or Arabic-shaped text.
Arabeyes' replacement exact_textout() supported the latter, but
turned out to break the former (with no warning from the Windows API
documentation, so it's not their fault).
So now I've got a second wrapper layer called general_textout(),
which splits the input string into substrings based on bidi
character class. Any character liable to cause bidi or shaping
behaviour if fed straight to ExtTextOutW is instead fed through
Arabeyes' exact_textout(), but the rest is fed straight to
ExtTextOutW as it used to be.
The effect appears to be that font linking is restored for all
characters _except_ Arabic and other bidi scripts, which means in
particular that we are no longer in a state of regression over 0.57.
(0.57 would have done font linking on Arabic as well, but would also
have misbidied it, so we've merely exchanged one failure mode for
another slightly less harmful one in that situation.)

behave like a pointer. In particular, the right thing to set a
HANDLE to to indicate that it's invalid is INVALID_HANDLE_VALUE, not
NULL. Crack down on sloppy use of NULL HANDLEs across all Windows
code.
(There is one oddity, which is that {Create,Open}FileMapping are
documented to return a NULL HANDLE instead of INVALID_HANDLE_VALUE
on failure. Shrug. If MS want to be inconsistent, I suppose I have
to live with it.)

unfriendly in an interactive session, because at 19200 baud it takes
nearly two seconds to receive that much data, and as long as the
data is flowing continuously Windows waits until it has a full
buffer. So here's another annoying flag in the winhandl API, which
restricts reads to length 1 so that serial output shows up as it
appears.
(I tried this yesterday, but without the OVERLAPPED fix in r6826 it
behaved very erratically. It now seems solid.)

channel to be replaced with a direct-tcpip connection to the
specified destination. This feature is mainly designed for use as a
local proxy: setting your local proxy command to `plink %proxyhost

fuss. Works on all platforms.

in place of making a network connection. This has involved a couple
of minor infrastructure changes:
- New dlg_label_change() function in the dialog.h interface, which
alters the label on a control. Only used, at present, to switch
the Host Name and Port boxes into Serial Line and Speed, which
means that any platform not implementing serial connections (i.e.
currently all but Windows) does not need to actually do anything
in this function. Yet.
- New small piece of infrastructure: cfg_launchable() determines
whether a Config structure describes a session ready to be
launched. This was previously determined by seeing if it had a
non-empty host name, but it has to check the serial line as well
so there's a centralised function for it. I haven't gone through
all front ends and arranged for this function to be used
everywhere it needs to be; so far I've only checked Windows.
- Similarly, cfg_dest() returns the destination of a connection
(host name or serial line) in a text format suitable for putting
into messages such as `Unable to connect to %s'.
[originally from svn r6815]
a serial port backend:
- In order to do simultaneous reading and writing on the same
HANDLE, you must enable overlapped access and pass an OVERLAPPED
structure to each ReadFile and WriteFile call. This would make
sense if it were an optional thing I could do if I wanted to do
the reading and writing in the same thread, but making it
mandatory even if I'm doing them in _different_ threads is just
annoying and arbitrary.
- Serial ports occasionally return length 0 from ReadFile, for no
particularly good reason. Fortunately serial ports also don't
have a real EOF condition to speak of, so ignoring EOFs is
actually a viable response in spite of sounding utterly gross.
Hence, handle_{input,output}_new() now accept a flags parameter,
which includes a flag to enable the OVERLAPPED bureaucracy and a
flag to cause EOFs to be ignored on input handles. The current
clients of winhandl.c do not use either of these.
