19    Description:
20    
21    Made some minor modifications to elabcore.sml to have source regions
22    be propagated more tightly -- resulting in better (i.e., smaller)
23    regions being reported in error- and debug messages.

28    Tag: blume-20041008-cmkw
29    Description:
30    
31    Fixed handling of keywords in .cm files: After seeing "is" the lexer
32    treats subsequent occurrences of "group", "library", "source", "is",
33    "*", and "-" as ordinary identifiers rather than keywords.
34    
35    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
36    is supposed to accept a tool argument called "source", but this did
37    not work because of the clash with the keyword.

43    Description:
44    
45    Assorted cleanup work:
46    
47      - got rid of intstrmap in favor of using the library's
48        hash table implementation
49      - threw out most of the pathnames stuff, as it was not used anyway
50      - simplified tokentable implementation
51      - fixed some minor spelling errors

57    Description:
58    
59    Cleaned up the absyn to reflect the invariant that HANDLE always
60    carries a FNexp as part of the type definition.  This eliminates some
61    superfluous sanity checks at runtime down the road.
62    
63    Some minor cleanup of the btrace code.

69    Description:
70    
71    Added hack to make slave mode work in the presence of the version
72    tool.  (Still, since the master does two passes over the code for
73    CMB.make, the release number gets bumped twice when slaves are
74    attached.  I don't know if this is worth fixing...)

79    Tag: blume-20040930-version
80    Description:
81    
82    * Moved the "version" magic into its own little library under
83    src/system/smlnj/internal.  This avoids expensive reconstruction
84    of a stable src/compiler/core.cm.
85    
86    * At the same time, structure CompilerVersion is now known as structure
87    SMLNJVersion.
88    
89    * Arranged for the version tool to NOT kick in when rebuilding the system
90      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
91      Also, loading the versiontool does not work when rebuilding the system
92      because CM is not properly initialized at that time.

97    Tag: blume-20040929-autoversion
98    Description:
99    
100    Implemented some CM magic to have
101        file src/compiler/TopLevel/main/version.sml
102    generated automagically.
103    The version is taken from two files: config/version and config/release.
104    The first is expected to contain a two-part version number such as 110.49.
105    The second should contain a single number, but it may be missing.
106    
107    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
108    time the version tool is loaded (which is the first time you say CMB.make),
109    then the tool will increment the value stored in config/release every
110    time CMB.make is invoked.
111    
112    The binfile format is now insensitive to anything beyond the first
113    two components of a version number, so bumping the release does not render
114    binfiles incompatible.  Auto-bumping can be used to keep track of versions
115    during development without invalidating existing binfiles.
116    
117    In any case, every CMB.make updates the date information in version.sml.
118    (This is the date that is printed in the banner.)

123    Tag: blume-20040928-controls
124    Description:
125    
126    Some cleanup of the controls code.
127    
128    ----------------------------------------------------------------------
129    Name: Matthias Blume (blume (at) tti - c (dot) org)
130    Date: 2004/09/27 22:08:00 CDT
131    Tag: blume-20040927-controls
132    Description:
133    
134    Added two pieces of functionality to the Controls interface:
135    
136    1.   val save'restore: 'a control -> unit -> unit
137    
138       grabs the current value of the control in stage 1 and restores it
139       in stage 2.
140    
141    2.   val set' : 'a control * 'a -> unit -> unit
142    
143       stores the given value into the control in stage 2 (i.e., delayed)
144       but does all error checking in stage 1.
145       (This is for string controls that need to do parse their argument --
146        something that might fail.  In some cases, notably in CM, one
147        already knows the intended argument but wants to delay the actual
148        assignment until a time when error recovery would be more difficult.)
149    
150    Changed the handling of controls in tool arguments to classes "sml" and
151    "lazysml":
152       - use Controls.save'restore as a more robust way of restoring the
153         old value (in particular: without having to re-parse the string)
154       - use controls to handle the "overload" keyword in the init group
155         (I believe this change actually fixes a long-standing obscure bug.)
156

158    Name: Matthias Blume (blume (at) tti - c (dot) org)
159    Date: 2004/09/27 17:00:00 CDT
160    Tag: blume-20040927-lazysml
161    Description:
162    
163    Added a new tool class called "lazysml" to CM's tool chest.  The only
164    difference to "sml" is that compilation is done with Control.lazysml
165    set to true.  A source of class "lazysml" is automatically recognized
166    by a file name suffix of ".lml".
167    
168    In addition to the above feature, the original class "sml" now also
169    supports a tool argument "lazy" which has the same effect.  As a
170    result, the following three lines are equivalent:
171    
172        foo.sml : lazysml
173        foo.sml : sml (lazy)
174        foo.sml (lazy)
175    
176    The setting goes into effect both during parsing and during
177    compilation.  The original setting is restored right after parsing and
178    after compilation, respectively.
179    
180    In addition to all the above, there is also a general mechanism to set
181    ANY of the "controls" that are available at the command line via
182    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
183    apply as well. (In fact, "lazy" is implemented as a special case of
184    the general mechanism.)
185    
186    The .cm file syntax uses a new keyword tool argument called "with".
187    There are several ways of indicating the desired settings:
188    
189        foo.sml (with:parser.quotations=true)
190        foo.sml (with:(name:parser.quotations value:true))
191        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
192        foo.sml (with:(name1=value1 name2=value2 ...))
193        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
194    
195        etc.
196    
197    Another possible abbreviation is to leave out the =v or value:v part
198    if the name refers to a boolean control (in which case the value is
199    taken to be true).  Thus, one could get lazy sml also by saying:
200    
201        foo.sml (with:parser.lazy-keyword=true)
202        foo.sml (with:parser.lazy-keyword)
203        foo.sml (with:(name:parser.lazy-keyword value:true))
204        foo.sml (with:(name:parser.lazy-keyword))

228    Description:
229    
230    1. Changed definition of type ControlRegistry.registry_tree to
231       include control_info (i.e., the name of the controlling environment
232       variable).
233    
234    2. Added command-line flags -e and -E to print the names of environment
235       variables that can be used to control internal settings.
236       (This uses the new API mentioned in 1.)

296    Description:
297    
298    Upon request by Johannes Joemann:
299

353    Bug fix from Carl Hauser:
354    
355    single_source_shortest_paths in dijkstra.sml was observed to get wrong
356    answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
357    
358    The problem is that following the expression A.update(dist,s,Num.zero)
359    it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

462    Description:
463    
464    Added C_UNION to c-calls/c-types.sml and updated the machinery
465    (ml-nlffigen, cproto.sml) that conveys C function interface
466    information to the code generator.
467    
468    However, the actual architecture-specific implementation of function
469    arguments and results that are C unions is still not implemented.

501    Description:
502    
503    - use paramAlloc to report c-calls with too many arguments
504      (for PPC version where parameter area is pre-allocated)
505    - added ccall_maxargspace to machspec (to implement the above)
506    - made "make" commend in CM's "make" tool configurable
507    - added option (default: on) for passing the name of the SML/NJ's "bin"
508      directory to "make"; the call looks like this:
509    
510         make <options> SMLNJ_BINDIR=<dir> <target>
511    
512      This can be used by the Makefile to, e.g., pick the "right" version
513      of ml-nlffigen.

522    NLFFI under Mac OS X now working (sort of).  This is largely untested,
523    though.
524    
525    Note:  1. You have to make a new, clean build of the runtime system.
526           2. There are new BOOTFILES, you have to use them!
527              (Doing the bootstrap process yourself would be *very* painful!
528               If you absolutely have to do it, build the system under
529               a different architecture and then cross-compile.)
530    
531    Version bumped to 110.46.1 to account for runtime data format changes.

555    Tag: blume-20040617-timer-unix
556    Description:
557    
558    Changed the interface of structures Timer and Unix to match the most
559    recent Basis spec.
560    
561    In the case of Unix there still seems to be an open/weird issue:
562    
563       The {text,bin}{In,Out}streamOf functions are supposed to create
564       fresh streams whenever they are called -- as opposed to have them
565       return the same stream every time.  This design is supposed to
566       prevent space leaks caused by proc values hanging on to streams.
567    
568       The reap function, on the other hand, is supposed to close the
569       streams.  This cannot be done without having a handle on the
570       stream in proc after all...
571    
572    I took the liberty to implement the following stopgap solution:
573    
574      The proc value hangs on to the most recently created stream(s).
575      Reap closes those.  If either or both of the two streams hadn't
576      been created at all yet, then reap will close the corresponding
577      file descriptors directly.
578    
579    PS: I don't understand the original space leak argument anymore.  If
580    a proc hangs on to the imperative stream, then I/O operations on those
581    will advance the state of the cached stream and avoid the space leak.

594    Tag: blume-20040525-group-owner
595    Description:
596    
597    CM now ignores (but still accepts) the "owner" information in group
598    descriptions.  The owner of a group is its next enclosing
599    library. Each group must have a unique owner.  (There is a virtual
600    "toplevel" library that owns groups which are not nested within a real
601    library.)  Previously, each group had to explicitly declare its owner,
602    and CM would check that such a declaration is correct.  The new scheme
603    is to have CM check that for each group there is precisely one owning
604    library.
605    
606    The advantage of the new scheme is that the programmer no longer needs
607    to maintain the somewhat annoying owner information.  The downside is
608    that CM cannot enforce the ownership rule across multiple runs of
609    CM.make.  Fortunately, enclosing the same group in two different
610    libraries A and B which are not part of the same program does not
611    cause real problems.

622    
623    Also, included a minor addition to ml-build.bat analogous to what was
624    done in blume-20040519-ml-build.

630    Description:
631    
632    Arranged for ml-build to clean up after itself a little bit better.
633    The script generates a temporary SML source file and compiles it using
634    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
635    gets rid of those at the end, so they don't accumulate under .cm.
636    
637    This required a minor change to install.sh because the name of the
638    metadata directory (default: .cm) is actually configurable at
639    installation time.

654    Description:
655    
656    Added previously missing support for many socket-related functions
657    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
658    for the voluminous patch!
659    
660    (I have not tested this patch under win32 yet.)
661    
662    Here is David's e-mail:
663    
664    Hi,
665    
666    Attached to this email you find a diff against sml/nj 110.45
667    that will enable socket support under Windows.
668    
669    To apply the patch (using unix or cygwin)
670    1) gunzip runtime.diff.gz
671    2) "cd" into "src/runtime" in the source tree of a fresh
672       110.45 installation.
673    3) patch -p 1 < [your/path/to]runtime.diff
674    
675    The code compiles fine but has NOT yet been extensively tested.
676    I only ran a few tests for basic socket client functionality
677    (which worked fine).  Especially the functions that use ioctl
678    are not tested at all and might not work (see below).
679    
680    I implemented this since we want to move to a newer version of sml/nj
681    but need socket support in order to use it.  This is the first time I
682    even had a look at the sml/nj source,  so please review my changes
683    before making this part of the distribution!  Here are a few issues
684    that I think might be better for someone to solve who is more
685    familiar with the sml/nj source (and socket programming):
686    
687    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
688      exception since I could not figure out what the windows equivalent
689      of these functions is
690    
691    - In sockets-osdep.h there are a some #include statements that are
692      only used in a few files that include sockets-osdep.h
693    
694    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
695      does not process its return value since I don't know how to
696      report an error upwards.
697    
698    - It would probably be good to have a call to WSACleanup() when
699      the library is unloaded (if there is such a possibility).
700      Otherwise I think Windows will take care of this automatically
701      when the process finishes.
702    
703    - I used ioctlsocket() as a replacement for ioctl() but I have
704      no idea if that is actually the proper replacement on Windows.
705    
706    - All these issues are marked in the code by "FIXME" comments.
707    
708    We use sml/nj extensively in our products and are quite happy
709    with it.  I hope this contribution will help you.
710    
711    Keep up the good work!
712    
713    David

751    in the "targets" file, then the installer will pull in sources for
752    everything.  (Notice that this refers to source code only.  Compiled
753    code is still only installed for modules that were requested explicitly
754    or which are required for other modules that were requested explicitly.)

788    Description:
789    
790    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
791    of SML/NJ.  The problem is that
792    
793       lib = dlopen(NULL, ...)
794       f   = dlsym(lib, "malloc");
795    
796    does not work on Windows unless we explicitly export symbols
797    such as 'malloc' during linking.  We fixed this by explicitly
798    exporting the required symbols with the magic gcc incantation:
799    
800        -Wl,--export-all cygwin.def
801    
802    where cygwin.def is a file containing all the symbols that
803    we wish to export.
804    
805    I suspect this is a Windows problem and we'll have to
806    do the same (somehow with windows compilers) when
807    we build the native win32 version with the system
808    calls LoadLibrary/GetProcAddress.
