19    Description:
21    Changed the interface of structures Timer and Unix to match the most
22    recent Basis spec.
24    In the case of Unix there still seems to be an open/weird issue:
26       The {text,bin}{In,Out}streamOf functions are supposed to create
27       fresh streams whenever they are called -- as opposed to have them
28       return the same stream every time.  This design is supposed to
29       prevent space leaks caused by proc values hanging on to streams.
31       The reap function, on the other hand, is supposed to close the
32       streams.  This cannot be done without having a handle on the
33       stream in proc after all...
35    I took the liberty to implement the following stopgap solution:
37      The proc value hangs on to the most recently created stream(s).
38      Reap closes those.  If either or both of the two streams hadn't
39      been created at all yet, then reap will close the corresponding
40      file descriptors directly.
42    PS: I don't understand the original space leak argument anymore.  If
43    a proc hangs on to the imperative stream, then I/O operations on those
44    will advance the state of the cached stream and avoid the space leak.

57    Tag: blume-20040525-group-owner
58    Description:
60    CM now ignores (but still accepts) the "owner" information in group
61    descriptions.  The owner of a group is its next enclosing
62    library. Each group must have a unique owner.  (There is a virtual
63    "toplevel" library that owns groups which are not nested within a real
64    library.)  Previously, each group had to explicitly declare its owner,
65    and CM would check that such a declaration is correct.  The new scheme
66    is to have CM check that for each group there is precisely one owning
67    library.
69    The advantage of the new scheme is that the programmer no longer needs
70    to maintain the somewhat annoying owner information.  The downside is
71    that CM cannot enforce the ownership rule across multiple runs of
72    CM.make.  Fortunately, enclosing the same group in two different
73    libraries A and B which are not part of the same program does not
74    cause real problems.

79    Tag: blume-20040520-win32
80    Description:
82    Made the win32 version work again.  (Strangely, a misplaced comma had
83    slipped into win32-process.c which prevented the runtime from being
84    compiled correctly.)
86    Also, included a minor addition to ml-build.bat analogous to what was
87    done in blume-20040519-ml-build.

92    Tag: blume-20040519-ml-build
93    Description:
95    Arranged for ml-build to clean up after itself a little bit better.
96    The script generates a temporary SML source file and compiles it using
97    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
98    gets rid of those at the end, so they don't accumulate under .cm.
100    This required a minor change to install.sh because the name of the
101    metadata directory (default: .cm) is actually configurable at
102    installation time.

110    Added Posix.IO.mk{Bin,Text}{Reader,Writer} by lifting their respective
111    implementations from internal modules PosixBinPrimIO and PosixTextPrimIO.

116    Tag: blume-20040511-win32sock
117    Description:
119    Added previously missing support for many socket-related functions
120    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
121    for the voluminous patch!
123    (I have not tested this patch under win32 yet.)
125    Here is David's e-mail:
127    Hi,
129    Attached to this email you find a diff against sml/nj 110.45
130    that will enable socket support under Windows.
132    To apply the patch (using unix or cygwin)
133    1) gunzip runtime.diff.gz
134    2) "cd" into "src/runtime" in the source tree of a fresh
135       110.45 installation.
136    3) patch -p 1 < [your/path/to]runtime.diff
138    The code compiles fine but has NOT yet been extensively tested.
139    I only ran a few tests for basic socket client functionality
140    (which worked fine).  Especially the functions that use ioctl
141    are not tested at all and might not work (see below).
143    I implemented this since we want to move to a newer version of sml/nj
144    but need socket support in order to use it.  This is the first time I
145    even had a look at the sml/nj source,  so please review my changes
146    before making this part of the distribution!  Here are a few issues
147    that I think might be better for someone to solve who is more
148    familiar with the sml/nj source (and socket programming):
150    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
151      exception since I could not figure out what the windows equivalent
152      of these functions is
154    - In sockets-osdep.h there are a some #include statements that are
155      only used in a few files that include sockets-osdep.h
157    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
158      does not process its return value since I don't know how to
159      report an error upwards.
161    - It would probably be good to have a call to WSACleanup() when
162      the library is unloaded (if there is such a possibility).
163      Otherwise I think Windows will take care of this automatically
164      when the process finishes.
166    - I used ioctlsocket() as a replacement for ioctl() but I have
167      no idea if that is actually the proper replacement on Windows.
169    - All these issues are marked in the code by "FIXME" comments.
171    We use sml/nj extensively in our products and are quite happy
172    with it.  I hope this contribution will help you.
174    Keep up the good work!
