1 Minimum Profit Data Manager (mpdm) TODO / Bug List
2 ==================================================
7 * 1056: Fill the overview document.
12 * 1061: On IRIX, iconv() doesn't have the "WCHAR_T" charset, so
13 iconv support doesn't seem to work there; but it has "UCS-4", which
14 is practically the same and it works, so there should be some
15 workaround to use it whenever "WCHAR_T" fails.
22 * 1063: Implement copy-on-write on array cloning.
23 * 1066: Implement a minimum time-to-live for values; never referenced values
24 younger than that will never be swept. Values under explicit [un]ref()
25 control won't have this, as they (should) never be used after being
26 unreferenced, so TTL will be unset after being unreferenced to 0. Anyway,
27 as this could mask possible sweeping errors, it has not been implemented yet.
28 * 1085: Use const wherever possible.
29 * 1094: Try an (optional) usage of pthreads to call sweep() in a low priority
30 thread, when nothing else is happening.
35 * 1000: All string operations should use wchar_t instead of char
36 (Closed by: #1001; Sat, 3 Jul 2004 11:14:00 +0200).
37 * 1001: Merge mpdm-branch-wchar
38 (Closes: #1000; Sun, 4 Jul 2004 11:06:00 +0200).
39 * 1002: mpdm_aget() and mpdm_aset() should accept negative offsets
40 (Mon, 12 Jul 2004 17:44:00 +0200).
41 * 1012: mpdm_startup() and mpdm_shutdown() (Thu, 26 Aug 2004 20:10:02 +0200)
42 * 1013: Move the hardwired '16' number of minimum elements to an
43 struct _mpdm element, set from mpdm_startup()
44 (Thu, 26 Aug 2004 20:10:18 +0200).
45 * 1014: Create a new high threshold for values, to force calling
46 mpdm_sweep() from mpdm_new() if that threshold is overpassed (this
47 will allow a limit to be imposed to the number of unreferenced
48 values) (Thu, 26 Aug 2004 20:26:21 +0200).
49 * 1019: Rework mpdm_dump() to avoid using dynamic values
50 (Wed, 08 Sep 2004 21:52:39 +0200).
51 * 1020: Set errno on errors (Discarded; Thu, 07 Oct 2004 17:11:52 +0200).
52 * 1003: Beyond ties; suppress all flags (except some internal ones as IVAL
53 or EXEC). Everything should be done with ties; for example, there
54 should exist a _CMP tie function that would be executed when two
55 values being compared have the same tie (or, better, the same _CMP
56 function). Specially, MPDM_STRING and MPDM_MULTIPLE should disappear.
57 A value will be assumed multiple when having a tie function _AEXPAND
58 (or _AGET, or so). Code will become incidentally clean (no more "if
59 flags & MPDM_" scattered through the code). Risky change!
60 (Discarded; Wed, 08 Dec 2004 09:48:27 +0100).
61 * 1005: Should ties be in a special source file, mpdm_t.c ?
62 (Discarded; Wed, 08 Dec 2004 09:49:06 +0100).
63 * 1011: Will the scripting language be included here, or as a
64 separated package? it could poison the mpdm concept as a 'low
65 level utility library' (Yes; Wed, 08 Dec 2004 09:51:55 +0100).
66 * 1010: Find a name for the scripting language (Mpsl should be
67 fine; Wed, 08 Dec 2004 09:52:32 +0100).
68 * 1026: Make the _mpdm control structure public
69 (Wed, 08 Dec 2004 11:34:54 +0100).
70 * 1025: Change non-dyn values. They should be stored in a pool of
71 values, and 'allocated' from within mpdm_new(). Two macros, for
72 instance MPDM_ND_BEGIN() and MPDM_ND_END(), could save
73 / restore a static index to that pool. Instead, the allocation
74 from the pool would just wrap (Wed, 08 Dec 2004 16:52:21 +0100).
75 * 1030: non-dyn array values are completely broken; the creation
76 should include the array of values and not take it from mpdm_alloc().
77 (Wed, 08 Dec 2004 19:16:05 +0100).
78 * 1031: Size in MPDM_ND_A() is superfluous, as it can be calculated
79 (Wed, 08 Dec 2004 22:12:57 +0100).
80 * 1033: Create a new mpdm_hexists() function
81 (Thu, 09 Dec 2004 11:19:03 +0100).
82 * 1037: Add caching support in values for real numbers (like ival).
83 (Sun, 12 Dec 2004 17:54:34 +0100).
84 * 1043: Change mpdm_write() so that it doesn't use printf(), but
85 wcstombs() and an small local buffer (Mon, 20 Dec 2004 08:41:20 -0800).
86 * 1045: mpdm_dump() should not use printf() for mpdm_string(), but
87 convert by hand using wcstombs() (Mon, 20 Dec 2004 08:44:52 -0800).
88 * 1044: mpdm_write() should include a 3rd argument, a separator
89 for the end of line (Mon, 20 Dec 2004 08:54:39 -0800).
90 * 1048: mpdm_rval() breaks locales (Wed, 05 Jan 2005 16:05:52 +0100).
91 * 1047: Change _mpdm_sym() to force the creation of all intermediate
92 arrays or hashes in the way. Also, it does not make much sense to
93 be in plain mpdm; it should be part of mpsl (Discarded;
94 Sat, 08 Jan 2005 21:30:55 +0100).
95 * 1016: Add optional iconv support
96 (Closed by #1055; Thu, 10 Mar 2005 13:26:54 +0100).
97 * 1054: Add a main() function, similar to the filp one
98 (Not applicable; Fri, 18 Mar 2005 06:46:06 +0100).
99 * 1032: Nondyn arrays must be protected in mpdm_aexpand(),
100 mpdm_acollapse(), etc (Fri, 18 Mar 2005 08:00:28 +0100).
101 * 1004: Create a tie function for mpdm_dump()
102 (No; Fri, 18 Mar 2005 08:04:19 +0100).
103 * 1057: Iconv objects can't be reused for different files, so
104 current implementation is faulty. Each iconv_t variable should
105 be stored inside the file value (Fri, 25 Mar 2005 02:24:10 +0100).
106 * 1055: Iconv support works, but is nearly useless; iconverters
107 should be associated to file descriptors, which are the only
108 place where iconv will really be used (Fri, 25 Mar 2005 03:04:26 +0100).
109 * 1058: Changeset on "2005-03-25 02:26 CET" (file descriptors in their's
110 own structure) broke mpsl (SIGSEGV's on compiling from file). Last
111 working version was "cvs update -D '2005/03/25 02:26'"
112 (Bug is in mpsl; Fri, 25 Mar 2005 12:17:21 +0100).
113 * 1015: The auto-sweep introduced by _mpdm.high_threshold is
114 extremely unsafe. At least, internal parts of mpdm should be
115 autosweep-safe (high_threshold abandoned; Mon, 28 Mar 2005 16:40:38 +0200).
116 * 1059: Get rid of ties. They are flexible and sexy, but add a complexity
117 that isn't worth (Sun, 03 Apr 2005 16:38:44 +0200).
118 * 1018: Support for optional features (like gdbm) should be stored
119 in an mpdm array or hash to easily ask for capabilities (gdbm support
120 dropped, and no other optional features; Sun, 03 Apr 2005 16:39:19 +0200).
121 * 1027: Store all static _tie... values in ties in the main
122 control structure (ties no longer exist; Sun, 03 Apr 2005 16:40:12 +0200).
123 * 1029: Store the regex cache in the main control structure
124 (Sun, 03 Apr 2005 16:40:32 +0200).
125 * 1028: With the closing of bugs #1026, #1027 and #1029, it should be
126 easy to have multiple mpdm engines, just by commuting the _mpdm
127 pointer. So, there should exist an mpdm_cleanup() function,
128 that would, after destroying values by calling mpdm_shutdown(),
129 free the rest of values stored inside. This kind of cleanup should
130 not be necessary on normal shutdown, as memory will be freed by
131 the operating system anyway (Doesn't seem necessary nor useful;
132 Mon, 04 Apr 2005 18:51:48 +0200).
133 * 1062: sprintf() (Not applicable, it should be implemented on mpsl instead;
134 Mon, 11 Apr 2005 17:52:38 +0200).
135 * 1060: Some old Unix systems (for example, IRIX) and mingw32
136 don't have the mbrtowc() function (they do have mbtowc(), though)
137 (Tue, 12 Apr 2005 18:55:42 +0200).
138 * 1017: Add optional gettext support (Sat, 16 Apr 2005 11:05:31 +0200).
139 * 1064: There should exist some way to detect the lack of gettext
140 support and set a translation hash (Closed by #1065;
141 Sat, 16 Apr 2005 11:32:11 +0200).
142 * 1071: The _cache_18n hash in mpdm_s.c has be moved to the main control
143 structure (Thu, 26 May 2005 14:01:17 +0200).
144 * 1072: mpdm_v should be renamed to mpdm_t (Thu, 26 May 2005 17:34:27 +0200).
145 * 1067: Get rid of symbols prefixed with _ (Thu, 26 May 2005 17:59:17 +0200).
146 * 1068: Rewrite the circular list of values as a double-list (i.e., with
147 links to previous) (Thu, 26 May 2005 18:48:56 +0200).
148 * 1069: The mpdm_free() function should dequeue the value about to be
149 destroyed; this way, it could be called from other functions, like
150 mpdm_unref() (Thu, 26 May 2005 18:48:56 +0200).
151 * 1070: Modify mpdm_unref() to optionally destroy a value when its
152 reference count gets to 0 (needs #1068 and #1069 closed) (No. This is not
153 that a good idea, as there are many places where values are referenced to
154 zero and later used, as in mpdm_asort(), or where semantics change, for
155 example, when mpdm_aset() returns the previous value;
156 Thu, 26 May 2005 20:28:33 +0200).
157 * 1073: Add a wcwidth() implementation for systems lacking it (for
158 example, mingw32) (Mon, 11 Jul 2005 07:55:31 +0200).
159 * 1074: Add multiline regex strings (Mon, 11 Jul 2005 15:57:06 +0200).
160 * 1076: If the string to be matched cannot be converted to mbs, both
161 mpdm_regex() and mpdm_sregex() abort (Sat, 22 Oct 2005 13:59:12 +0200).
162 * 1077: mpdm_mbstowcs() should return "" instead of NULL when converting
163 an empty string (Sat, 22 Oct 2005 18:00:50 +0200).
164 * 1075: mpdm_regex() is broken in UTF-8 environments,
165 as it's assuming that the matching information returned by regexec()
166 (in byte count) can be directly used as wchar_t offsets
167 (Sat, 22 Oct 2005 18:12:20 +0200).
168 * 1078: mpdm_sregex() is broken in UTF-8 environments,
169 as it's assuming that the matching information returned by regexec()
170 (in byte count) can be directly used as wchar_t offsets
171 (Sat, 22 Oct 2005 22:50:51 +0200).
172 * 1079: Previous match information for regexes contain wrong
173 values if the string to be matched is multibyte
174 (Sun, 23 Oct 2005 21:21:43 +0200).
175 * 1080: Related to #1079, multiline regexes don't work in
176 multibyte locales, as it's also relying on rm containing
177 offsets in characters (Sun, 23 Oct 2005 21:35:08 +0200).
178 * 1081: Document all the MPDM_ macros (Tue, 22 Nov 2005 17:03:40 +0100).
179 * 1082: Add categories to mp_doccer documentation
180 (Tue, 22 Nov 2005 17:03:45 +0100).
181 * 1065: There should exist some way to detect lack of gettext support
182 in runtime to add implementation-specific workarounds as, for
183 example, filling the i18n cache manually. This is something like
184 a reopening of bug #1018 (Implemented by returning failure from
185 mpdm_gettext_domain(); Thu, 19 Jan 2006 08:15:21 +0100).
186 * 1084: As mpdm_sregex() now executes code, all values should be
187 referenced to avoid undesired sweeps (Mon, 13 Feb 2006 09:12:41 +0100).
188 * 1083: Add pipe support (Tue, 09 May 2006 18:02:19 +0200).
189 * 1087: Add pipe support for win32 (Fri, 12 May 2006 08:04:30 +0200).
190 * 1086: Add a way to get the 'library' (/usr/PREFIX/share on Unix
191 and the "Program Files" directory on Windows) and 'home' (~ and
192 "My Documents") directories (Fri, 12 May 2006 13:26:32 +0200).
193 * 1088: mpdm_sprintf() (Tue, 23 May 2006 18:07:58 +0200).
194 * 1091: Change CONFOPT_NULL_HASH to a runtime switch using an
195 environment variable (Wed, 13 Sep 2006 16:07:18 +0200).
196 * 1006: stat() (Tue, 10 Oct 2006 13:00:54 +0200).
197 * 1007: chmod() (Tue, 10 Oct 2006 13:00:54 +0200).
198 * 1089: Change mpdm_cmp() to use wcscoll() instead of wcscmp()
199 (Tue, 10 Oct 2006 13:54:36 +0200).
200 * 1092: fseek() (Thu, 12 Oct 2006 09:54:34 +0200).
201 * 1093: ftell() (Thu, 12 Oct 2006 09:54:34 +0200).
202 * 1090: Sort the array in mpdm_glob() to show directories first
203 (Fri, 10 Nov 2006 17:32:27 +0100).
204 * 1095: The %c directive in sprintf() should work with Unicode
205 (or wchar_t) characters (Mon, 11 Jun 2007 08:42:02 +0200).
206 * 1096: On mpdm_sregex(), substitute all unescaped & with the regex match
207 (Mon, 18 Jun 2007 12:23:37 +0200).
208 * 1097: Fixed a bug in offset processing in mpdm_sregex()
209 (Mon, 18 Jun 2007 13:54:24 +0200).
