19    Description:
20    
21    Some rationalization of names:
22    
23       structure BTrace -> structure TDPInstrument
24       etc.
25    
26    This is is preparation of using the original back-trace
27    instrumentation for other purposes.  "TDP" stands for
28    Trace/Debug/Profile.
29    
30    The control flag controlling whether instrumentation is on or off is now
31    registered under a different name, so instead of running sml as
32    
33     sml -Cinstrument.btrace-mode=true
34    
35    one has to say
36    
37     sml -Ctdp.instrument=true

43    Description:
44    
45    Made some minor modifications to elabcore.sml to have source regions
46    be propagated more tightly -- resulting in better (i.e., smaller)
47    regions being reported in error- and debug messages.

52    Tag: blume-20041008-cmkw
53    Description:
54    
55    Fixed handling of keywords in .cm files: After seeing "is" the lexer
56    treats subsequent occurrences of "group", "library", "source", "is",
57    "*", and "-" as ordinary identifiers rather than keywords.
58    
59    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
60    is supposed to accept a tool argument called "source", but this did
61    not work because of the clash with the keyword.

67    Description:
68    
69    Assorted cleanup work:
70    
71      - got rid of intstrmap in favor of using the library's
72        hash table implementation
73      - threw out most of the pathnames stuff, as it was not used anyway
74      - simplified tokentable implementation
75      - fixed some minor spelling errors

81    Description:
82    
83    Cleaned up the absyn to reflect the invariant that HANDLE always
84    carries a FNexp as part of the type definition.  This eliminates some
85    superfluous sanity checks at runtime down the road.
86    
87    Some minor cleanup of the btrace code.

92    Tag: blume-20041001-slave
93    Description:
94    
95    Added hack to make slave mode work in the presence of the version
96    tool.  (Still, since the master does two passes over the code for
97    CMB.make, the release number gets bumped twice when slaves are
98    attached.  I don't know if this is worth fixing...)

103    Tag: blume-20040930-version
104    Description:
105    
106    * Moved the "version" magic into its own little library under
107    src/system/smlnj/internal.  This avoids expensive reconstruction
108    of a stable src/compiler/core.cm.
109    
110    * At the same time, structure CompilerVersion is now known as structure
111    SMLNJVersion.
112    
113    * Arranged for the version tool to NOT kick in when rebuilding the system
114      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
115      Also, loading the versiontool does not work when rebuilding the system
116      because CM is not properly initialized at that time.

121    Tag: blume-20040929-autoversion
122    Description:
123    
124    Implemented some CM magic to have
125        file src/compiler/TopLevel/main/version.sml
126    generated automagically.
127    The version is taken from two files: config/version and config/release.
128    The first is expected to contain a two-part version number such as 110.49.
129    The second should contain a single number, but it may be missing.
130    
131    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
132    time the version tool is loaded (which is the first time you say CMB.make),
133    then the tool will increment the value stored in config/release every
134    time CMB.make is invoked.
135    
136    The binfile format is now insensitive to anything beyond the first
137    two components of a version number, so bumping the release does not render
138    binfiles incompatible.  Auto-bumping can be used to keep track of versions
139    during development without invalidating existing binfiles.
140    
141    In any case, every CMB.make updates the date information in version.sml.
142    (This is the date that is printed in the banner.)

147    Tag: blume-20040928-controls
148    Description:
149    
150    Some cleanup of the controls code.
151    
152    ----------------------------------------------------------------------
153    Name: Matthias Blume (blume (at) tti - c (dot) org)
154    Date: 2004/09/27 22:08:00 CDT
155    Tag: blume-20040927-controls
156    Description:
157    
158    Added two pieces of functionality to the Controls interface:
159    
160    1.   val save'restore: 'a control -> unit -> unit
161    
162       grabs the current value of the control in stage 1 and restores it
163       in stage 2.
164    
165    2.   val set' : 'a control * 'a -> unit -> unit
166    
167       stores the given value into the control in stage 2 (i.e., delayed)
168       but does all error checking in stage 1.
169       (This is for string controls that need to do parse their argument --
170        something that might fail.  In some cases, notably in CM, one
171        already knows the intended argument but wants to delay the actual
172        assignment until a time when error recovery would be more difficult.)
173    
174    Changed the handling of controls in tool arguments to classes "sml" and
175    "lazysml":
176       - use Controls.save'restore as a more robust way of restoring the
177         old value (in particular: without having to re-parse the string)
178       - use controls to handle the "overload" keyword in the init group
179         (I believe this change actually fixes a long-standing obscure bug.)
180

183    Date: 2004/09/27 17:00:00 CDT
184    Tag: blume-20040927-lazysml
185    Description:
186    
187    Added a new tool class called "lazysml" to CM's tool chest.  The only
188    difference to "sml" is that compilation is done with Control.lazysml
189    set to true.  A source of class "lazysml" is automatically recognized
190    by a file name suffix of ".lml".
191    
192    In addition to the above feature, the original class "sml" now also
193    supports a tool argument "lazy" which has the same effect.  As a
194    result, the following three lines are equivalent:
195    
196        foo.sml : lazysml
197        foo.sml : sml (lazy)
198        foo.sml (lazy)
199    
200    The setting goes into effect both during parsing and during
201    compilation.  The original setting is restored right after parsing and
202    after compilation, respectively.
203    
204    In addition to all the above, there is also a general mechanism to set
205    ANY of the "controls" that are available at the command line via
206    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
207    apply as well. (In fact, "lazy" is implemented as a special case of
208    the general mechanism.)
209    
210    The .cm file syntax uses a new keyword tool argument called "with".
211    There are several ways of indicating the desired settings:
212    
213        foo.sml (with:parser.quotations=true)
214        foo.sml (with:(name:parser.quotations value:true))
215        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
216        foo.sml (with:(name1=value1 name2=value2 ...))
217        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
218    
219        etc.
220    
221    Another possible abbreviation is to leave out the =v or value:v part
222    if the name refers to a boolean control (in which case the value is
223    taken to be true).  Thus, one could get lazy sml also by saying:
224    
225        foo.sml (with:parser.lazy-keyword=true)
226        foo.sml (with:parser.lazy-keyword)
227        foo.sml (with:(name:parser.lazy-keyword value:true))
228        foo.sml (with:(name:parser.lazy-keyword))

252    Description:
253    
254    1. Changed definition of type ControlRegistry.registry_tree to
255       include control_info (i.e., the name of the controlling environment
256       variable).
257    
258    2. Added command-line flags -e and -E to print the names of environment
259       variables that can be used to control internal settings.
260       (This uses the new API mentioned in 1.)

463      (Thanks to David King at Motorola for catching this.)
464    
465    - several bugfixes provided or suggested by David Hansel at Reactive Systems:
466      - added a test for tm==NULL to gmtime.c and localtime.c
467      - applied patch for incorrect GetFileTime under win32
468      - toSeconds -> toMilliseconds in Win32/win32-process.sml

550           2. There are new BOOTFILES, you have to use them!
551              (Doing the bootstrap process yourself would be *very* painful!
552               If you absolutely have to do it, build the system under
553               a different architecture and then cross-compile.)

579    Tag: blume-20040617-timer-unix
580    Description:
581    
582    Changed the interface of structures Timer and Unix to match the most
583    recent Basis spec.
584    
585    In the case of Unix there still seems to be an open/weird issue:
586    
587       The {text,bin}{In,Out}streamOf functions are supposed to create
588       fresh streams whenever they are called -- as opposed to have them
589       return the same stream every time.  This design is supposed to
590       prevent space leaks caused by proc values hanging on to streams.
591    
592       The reap function, on the other hand, is supposed to close the
593       streams.  This cannot be done without having a handle on the
594       stream in proc after all...
595    
596    I took the liberty to implement the following stopgap solution:
597    
598      The proc value hangs on to the most recently created stream(s).
599      Reap closes those.  If either or both of the two streams hadn't
600      been created at all yet, then reap will close the corresponding
601      file descriptors directly.
602    
603    PS: I don't understand the original space leak argument anymore.  If
604    a proc hangs on to the imperative stream, then I/O operations on those
605    will advance the state of the cached stream and avoid the space leak.

618    Tag: blume-20040525-group-owner
619    Description:
620    
621    CM now ignores (but still accepts) the "owner" information in group
622    descriptions.  The owner of a group is its next enclosing
623    library. Each group must have a unique owner.  (There is a virtual
624    "toplevel" library that owns groups which are not nested within a real
625    library.)  Previously, each group had to explicitly declare its owner,
626    and CM would check that such a declaration is correct.  The new scheme
627    is to have CM check that for each group there is precisely one owning
628    library.
629    
630    The advantage of the new scheme is that the programmer no longer needs
631    to maintain the somewhat annoying owner information.  The downside is
632    that CM cannot enforce the ownership rule across multiple runs of
633    CM.make.  Fortunately, enclosing the same group in two different
634    libraries A and B which are not part of the same program does not
635    cause real problems.

654    Description:
655    
656    Arranged for ml-build to clean up after itself a little bit better.
657    The script generates a temporary SML source file and compiles it using
658    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
659    gets rid of those at the end, so they don't accumulate under .cm.
660    
661    This required a minor change to install.sh because the name of the
662    metadata directory (default: .cm) is actually configurable at
663    installation time.

678    Description:
679    
680    Added previously missing support for many socket-related functions
681    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
682    for the voluminous patch!
683    
684    (I have not tested this patch under win32 yet.)
685    
686    Here is David's e-mail:
687    
688    Hi,
689    
690    Attached to this email you find a diff against sml/nj 110.45
691    that will enable socket support under Windows.
692    
693    To apply the patch (using unix or cygwin)
694    1) gunzip runtime.diff.gz
695    2) "cd" into "src/runtime" in the source tree of a fresh
696       110.45 installation.
697    3) patch -p 1 < [your/path/to]runtime.diff
698    
699    The code compiles fine but has NOT yet been extensively tested.
700    I only ran a few tests for basic socket client functionality
701    (which worked fine).  Especially the functions that use ioctl
702    are not tested at all and might not work (see below).
703    
704    I implemented this since we want to move to a newer version of sml/nj
705    but need socket support in order to use it.  This is the first time I
706    even had a look at the sml/nj source,  so please review my changes
707    before making this part of the distribution!  Here are a few issues
708    that I think might be better for someone to solve who is more
709    familiar with the sml/nj source (and socket programming):
710    
711    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
712      exception since I could not figure out what the windows equivalent
713      of these functions is
714    
715    - In sockets-osdep.h there are a some #include statements that are
716      only used in a few files that include sockets-osdep.h
717    
718    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
719      does not process its return value since I don't know how to
720      report an error upwards.
721    
722    - It would probably be good to have a call to WSACleanup() when
723      the library is unloaded (if there is such a possibility).
724      Otherwise I think Windows will take care of this automatically
725      when the process finishes.
726    
727    - I used ioctlsocket() as a replacement for ioctl() but I have
728      no idea if that is actually the proper replacement on Windows.
729    
730    - All these issues are marked in the code by "FIXME" comments.
731    
732    We use sml/nj extensively in our products and are quite happy
733    with it.  I hope this contribution will help you.
734    
735    Keep up the good work!
736    
737    David

812    Description:
813    
814    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
815    of SML/NJ.  The problem is that
816    
817       lib = dlopen(NULL, ...)
818       f   = dlsym(lib, "malloc");
819    
820    does not work on Windows unless we explicitly export symbols
821    such as 'malloc' during linking.  We fixed this by explicitly
822    exporting the required symbols with the magic gcc incantation:
823    
824        -Wl,--export-all cygwin.def
825    
826    where cygwin.def is a file containing all the symbols that
827    we wish to export.
828    
829    I suspect this is a Windows problem and we'll have to
830    do the same (somehow with windows compilers) when
831    we build the native win32 version with the system
832    calls LoadLibrary/GetProcAddress.
