1 Minimum Profit Data Manager (MPDM) TODO / Bug List
2 ==================================================
12 * 1056: Finish the overview document.
13 * 1103: mpdm_home_dir() calls strcat() insecurely.
14 * 1104: mpdm_app_dir() calls strcat() insecurely.
21 * 1063: Implement copy-on-write on array cloning.
22 * 1066: Implement a minimum time-to-live for values; never referenced values
23 younger than that will never be swept. Values under explicit [un]ref()
24 control won't have this, as they (should) never be used after being
25 unreferenced, so TTL will be unset after being unreferenced to 0. Anyway,
26 as this could mask possible sweeping errors, it has not been implemented yet.
27 * 1094: Try an (optional) usage of pthreads to call sweep() in a low priority
28 thread, when nothing else is happening.
29 * 1101: Move mpdm_sym(), mpdm_sget() and mpdm_sset() to MPSL, as they
30 don't really belong here.
31 * 1105: Try another approach: store in the circular queue only the
32 unreferenced values; the others will be completely unqueued. This way,
33 values to be swept are immediately found. On the other side, mpdm_ref()
34 and mpdm_unref() will be much expensive, as they will en/dequeue values
35 depending of v->ref 0 or 1.
36 * 1115: Invert mpdm_split() arguments.
37 * 1116: Invert mpdm_join() arguments.
38 * 1117: Invert mpdm_sscanf() arguments.
39 * 1118: Invert mpdm_regex() arguments.
40 * 1119: Invert mpdm_sregex() arguments.
41 * 1120: Drop completely the garbage collection and convert it to a pure
42 reference-counting system.
47 * 1000: All string operations should use wchar_t instead of char
48 (Closed by: #1001; Sat, 3 Jul 2004 11:14:00 +0200).
49 * 1001: Merge mpdm-branch-wchar
50 (Closes: #1000; Sun, 4 Jul 2004 11:06:00 +0200).
51 * 1002: mpdm_aget() and mpdm_aset() should accept negative offsets
52 (Mon, 12 Jul 2004 17:44:00 +0200).
53 * 1012: mpdm_startup() and mpdm_shutdown() (Thu, 26 Aug 2004 20:10:02 +0200)
54 * 1013: Move the hardwired '16' number of minimum elements to an
55 struct _mpdm element, set from mpdm_startup()
56 (Thu, 26 Aug 2004 20:10:18 +0200).
57 * 1014: Create a new high threshold for values, to force calling
58 mpdm_sweep() from mpdm_new() if that threshold is overpassed (this
59 will allow a limit to be imposed to the number of unreferenced
60 values) (Thu, 26 Aug 2004 20:26:21 +0200).
61 * 1019: Rework mpdm_dump() to avoid using dynamic values
62 (Wed, 08 Sep 2004 21:52:39 +0200).
63 * 1020: Set errno on errors (Discarded; Thu, 07 Oct 2004 17:11:52 +0200).
64 * 1003: Beyond ties; suppress all flags (except some internal ones as IVAL
65 or EXEC). Everything should be done with ties; for example, there
66 should exist a _CMP tie function that would be executed when two
67 values being compared have the same tie (or, better, the same _CMP
68 function). Specially, MPDM_STRING and MPDM_MULTIPLE should disappear.
69 A value will be assumed multiple when having a tie function _AEXPAND
70 (or _AGET, or so). Code will become incidentally clean (no more "if
71 flags & MPDM_" scattered through the code). Risky change!
72 (Discarded; Wed, 08 Dec 2004 09:48:27 +0100).
73 * 1005: Should ties be in a special source file, mpdm_t.c ?
74 (Discarded; Wed, 08 Dec 2004 09:49:06 +0100).
75 * 1011: Will the scripting language be included here, or as a
76 separated package? it could poison the mpdm concept as a 'low
77 level utility library' (Yes; Wed, 08 Dec 2004 09:51:55 +0100).
78 * 1010: Find a name for the scripting language (Mpsl should be
79 fine; Wed, 08 Dec 2004 09:52:32 +0100).
80 * 1026: Make the _mpdm control structure public
81 (Wed, 08 Dec 2004 11:34:54 +0100).
82 * 1025: Change non-dyn values. They should be stored in a pool of
83 values, and 'allocated' from within mpdm_new(). Two macros, for
84 instance MPDM_ND_BEGIN() and MPDM_ND_END(), could save
85 / restore a static index to that pool. Instead, the allocation
86 from the pool would just wrap (Wed, 08 Dec 2004 16:52:21 +0100).
87 * 1030: non-dyn array values are completely broken; the creation
88 should include the array of values and not take it from mpdm_alloc().
89 (Wed, 08 Dec 2004 19:16:05 +0100).
90 * 1031: Size in MPDM_ND_A() is superfluous, as it can be calculated
91 (Wed, 08 Dec 2004 22:12:57 +0100).
92 * 1033: Create a new mpdm_hexists() function
93 (Thu, 09 Dec 2004 11:19:03 +0100).
94 * 1037: Add caching support in values for real numbers (like ival).
95 (Sun, 12 Dec 2004 17:54:34 +0100).
96 * 1043: Change mpdm_write() so that it doesn't use printf(), but
97 wcstombs() and an small local buffer (Mon, 20 Dec 2004 08:41:20 -0800).
98 * 1045: mpdm_dump() should not use printf() for mpdm_string(), but
99 convert by hand using wcstombs() (Mon, 20 Dec 2004 08:44:52 -0800).
100 * 1044: mpdm_write() should include a 3rd argument, a separator
101 for the end of line (Mon, 20 Dec 2004 08:54:39 -0800).
102 * 1048: mpdm_rval() breaks locales (Wed, 05 Jan 2005 16:05:52 +0100).
103 * 1047: Change _mpdm_sym() to force the creation of all intermediate
104 arrays or hashes in the way. Also, it does not make much sense to
105 be in plain mpdm; it should be part of mpsl (Discarded;
106 Sat, 08 Jan 2005 21:30:55 +0100).
107 * 1016: Add optional iconv support
108 (Closed by #1055; Thu, 10 Mar 2005 13:26:54 +0100).
109 * 1054: Add a main() function, similar to the filp one
110 (Not applicable; Fri, 18 Mar 2005 06:46:06 +0100).
111 * 1032: Nondyn arrays must be protected in mpdm_aexpand(),
112 mpdm_acollapse(), etc (Fri, 18 Mar 2005 08:00:28 +0100).
113 * 1004: Create a tie function for mpdm_dump()
114 (No; Fri, 18 Mar 2005 08:04:19 +0100).
115 * 1057: Iconv objects can't be reused for different files, so
116 current implementation is faulty. Each iconv_t variable should
117 be stored inside the file value (Fri, 25 Mar 2005 02:24:10 +0100).
118 * 1055: Iconv support works, but is nearly useless; iconverters
119 should be associated to file descriptors, which are the only
120 place where iconv will really be used (Fri, 25 Mar 2005 03:04:26 +0100).
121 * 1058: Changeset on "2005-03-25 02:26 CET" (file descriptors in their's
122 own structure) broke mpsl (SIGSEGV's on compiling from file). Last
123 working version was "cvs update -D '2005/03/25 02:26'"
124 (Bug is in mpsl; Fri, 25 Mar 2005 12:17:21 +0100).
125 * 1015: The auto-sweep introduced by _mpdm.high_threshold is
126 extremely unsafe. At least, internal parts of mpdm should be
127 autosweep-safe (high_threshold abandoned; Mon, 28 Mar 2005 16:40:38 +0200).
128 * 1059: Get rid of ties. They are flexible and sexy, but add a complexity
129 that isn't worth (Sun, 03 Apr 2005 16:38:44 +0200).
130 * 1018: Support for optional features (like gdbm) should be stored
131 in an mpdm array or hash to easily ask for capabilities (gdbm support
132 dropped, and no other optional features; Sun, 03 Apr 2005 16:39:19 +0200).
133 * 1027: Store all static _tie... values in ties in the main
134 control structure (ties no longer exist; Sun, 03 Apr 2005 16:40:12 +0200).
135 * 1029: Store the regex cache in the main control structure
136 (Sun, 03 Apr 2005 16:40:32 +0200).
137 * 1028: With the closing of bugs #1026, #1027 and #1029, it should be
138 easy to have multiple mpdm engines, just by commuting the _mpdm
139 pointer. So, there should exist an mpdm_cleanup() function,
140 that would, after destroying values by calling mpdm_shutdown(),
141 free the rest of values stored inside. This kind of cleanup should
142 not be necessary on normal shutdown, as memory will be freed by
143 the operating system anyway (Doesn't seem necessary nor useful;
144 Mon, 04 Apr 2005 18:51:48 +0200).
145 * 1062: sprintf() (Not applicable, it should be implemented on mpsl instead;
146 Mon, 11 Apr 2005 17:52:38 +0200).
147 * 1060: Some old Unix systems (for example, IRIX) and mingw32
148 don't have the mbrtowc() function (they do have mbtowc(), though)
149 (Tue, 12 Apr 2005 18:55:42 +0200).
150 * 1017: Add optional gettext support (Sat, 16 Apr 2005 11:05:31 +0200).
151 * 1064: There should exist some way to detect the lack of gettext
152 support and set a translation hash (Closed by #1065;
153 Sat, 16 Apr 2005 11:32:11 +0200).
154 * 1071: The _cache_18n hash in mpdm_s.c has be moved to the main control
155 structure (Thu, 26 May 2005 14:01:17 +0200).
156 * 1072: mpdm_v should be renamed to mpdm_t (Thu, 26 May 2005 17:34:27 +0200).
157 * 1067: Get rid of symbols prefixed with _ (Thu, 26 May 2005 17:59:17 +0200).
158 * 1068: Rewrite the circular list of values as a double-list (i.e., with
159 links to previous) (Thu, 26 May 2005 18:48:56 +0200).
160 * 1069: The mpdm_free() function should dequeue the value about to be
161 destroyed; this way, it could be called from other functions, like
162 mpdm_unref() (Thu, 26 May 2005 18:48:56 +0200).
163 * 1070: Modify mpdm_unref() to optionally destroy a value when its
164 reference count gets to 0 (needs #1068 and #1069 closed) (No. This is not
165 that a good idea, as there are many places where values are referenced to
166 zero and later used, as in mpdm_asort(), or where semantics change, for
167 example, when mpdm_aset() returns the previous value;
168 Thu, 26 May 2005 20:28:33 +0200).
169 * 1073: Add a wcwidth() implementation for systems lacking it (for
170 example, mingw32) (Mon, 11 Jul 2005 07:55:31 +0200).
171 * 1074: Add multiline regex strings (Mon, 11 Jul 2005 15:57:06 +0200).
172 * 1076: If the string to be matched cannot be converted to mbs, both
173 mpdm_regex() and mpdm_sregex() abort (Sat, 22 Oct 2005 13:59:12 +0200).
174 * 1077: mpdm_mbstowcs() should return "" instead of NULL when converting
175 an empty string (Sat, 22 Oct 2005 18:00:50 +0200).
176 * 1075: mpdm_regex() is broken in UTF-8 environments,
177 as it's assuming that the matching information returned by regexec()
178 (in byte count) can be directly used as wchar_t offsets
179 (Sat, 22 Oct 2005 18:12:20 +0200).
180 * 1078: mpdm_sregex() is broken in UTF-8 environments,
181 as it's assuming that the matching information returned by regexec()
182 (in byte count) can be directly used as wchar_t offsets
183 (Sat, 22 Oct 2005 22:50:51 +0200).
184 * 1079: Previous match information for regexes contain wrong
185 values if the string to be matched is multibyte
186 (Sun, 23 Oct 2005 21:21:43 +0200).
187 * 1080: Related to #1079, multiline regexes don't work in
188 multibyte locales, as it's also relying on rm containing
189 offsets in characters (Sun, 23 Oct 2005 21:35:08 +0200).
190 * 1081: Document all the MPDM_ macros (Tue, 22 Nov 2005 17:03:40 +0100).
191 * 1082: Add categories to mp_doccer documentation
192 (Tue, 22 Nov 2005 17:03:45 +0100).
193 * 1065: There should exist some way to detect lack of gettext support
194 in runtime to add implementation-specific workarounds as, for
195 example, filling the i18n cache manually. This is something like
196 a reopening of bug #1018 (Implemented by returning failure from
197 mpdm_gettext_domain(); Thu, 19 Jan 2006 08:15:21 +0100).
198 * 1084: As mpdm_sregex() now executes code, all values should be
199 referenced to avoid undesired sweeps (Mon, 13 Feb 2006 09:12:41 +0100).
200 * 1083: Add pipe support (Tue, 09 May 2006 18:02:19 +0200).
201 * 1087: Add pipe support for win32 (Fri, 12 May 2006 08:04:30 +0200).
202 * 1086: Add a way to get the 'library' (/usr/PREFIX/share on Unix
203 and the "Program Files" directory on Windows) and 'home' (~ and
204 "My Documents") directories (Fri, 12 May 2006 13:26:32 +0200).
205 * 1088: mpdm_sprintf() (Tue, 23 May 2006 18:07:58 +0200).
206 * 1091: Change CONFOPT_NULL_HASH to a runtime switch using an
207 environment variable (Wed, 13 Sep 2006 16:07:18 +0200).
208 * 1006: stat() (Tue, 10 Oct 2006 13:00:54 +0200).
209 * 1007: chmod() (Tue, 10 Oct 2006 13:00:54 +0200).
210 * 1089: Change mpdm_cmp() to use wcscoll() instead of wcscmp()
211 (Tue, 10 Oct 2006 13:54:36 +0200).
212 * 1092: fseek() (Thu, 12 Oct 2006 09:54:34 +0200).
213 * 1093: ftell() (Thu, 12 Oct 2006 09:54:34 +0200).
214 * 1090: Sort the array in mpdm_glob() to show directories first
215 (Fri, 10 Nov 2006 17:32:27 +0100).
216 * 1095: The %c directive in sprintf() should work with Unicode
217 (or wchar_t) characters (Mon, 11 Jun 2007 08:42:02 +0200).
218 * 1096: On mpdm_sregex(), substitute all unescaped & with the regex match
219 (Mon, 18 Jun 2007 12:23:37 +0200).
220 * 1097: Fixed a bug in offset processing in mpdm_sregex()
221 (Mon, 18 Jun 2007 13:54:24 +0200).
222 * 1098: mpdm_cmp(NULL, NULL) should return 0
223 (Wed, 12 Sep 2007 09:50:08 +0200).
224 * 1100: Allow for a component in a 'symbol' managed by mpdm_sym() to
225 be an executable (Tue, 25 Sep 2007 18:13:38 +0200).
226 * 1099: mpdm_cmp() should be optimized to return 0 if two arrays
227 are *the same* (Closed by 1102; Fri, 28 Sep 2007 13:01:55 +0200).
228 * 1102: Optimize mpdm_cmp() when comparing the same values
229 (Fri, 28 Sep 2007 13:10:44 +0200).
230 * 1107: Implement functions to set the ival and rval of a value
231 (Thu, 29 Nov 2007 09:07:33 +0100).
232 * 1106: Implement a function to get the file handle of an MPDM_FILE type
233 (Thu, 29 Nov 2007 13:12:48 +0100).
234 * 1085: Use const wherever possible (Fri, 18 Jan 2008 14:10:12 +0100).
235 * 1108: Fix the %% usage in mpdm_sprintf()
236 (Sun, 30 Mar 2008 17:41:02 +0200).
237 * 1061: On IRIX, iconv() doesn't have the "WCHAR_T" charset, so
238 iconv support doesn't seem to work there; but it has "UCS-4", which
239 is practically the same and it works, so there should be some
240 workaround to use it whenever "WCHAR_T" fails
241 (Mon, 07 Apr 2008 14:55:30 +0200).
242 * 1109: expand_ampersands() kills all backslashes
243 (Tue, 03 Feb 2009 07:25:21 +0100).
244 * 1110: Win32 file globbing fails when a leading directory is specified
245 (Wed, 25 Mar 2009 17:04:29 +0100).
246 * 1111: Document mpdm_sscanf() (Wed, 26 Aug 2009 09:07:01 +0200).
247 * 1112: Document the `DETECTED_ENCODING' variable
248 (Wed, 26 Aug 2009 09:40:03 +0200).
249 * 1113: Document the `TEMP_ENCODING' variable
250 (Wed, 26 Aug 2009 09:40:03 +0200).
251 * 1114: Fixed mpdm_sset() when the previous-to-last value to be
252 assigned is executable (Tue, 22 Dec 2009 10:05:12 +0100).
