1 2005-11-08 Jonathan Pryor <jonpryor@vt.edu>
3 * Catalog.cs: Exception safety improvements (don't let memory leak!); check
4 for errors with bindtextdomain(3) et. al.
6 2005-11-08 Jonathan Pryor <jonpryor@vt.edu>
8 * UnixPipes.cs: Provide Equals, GetHashCode, and operator==/operator!= to
9 conform with FxCop guidelines for structures.
11 2005-11-03 Jonathan Pryor <jonpryor@vt.edu>
13 * FileTypes.cs, UnixFileSystemInfo.cs: s/FIFO/Fifo/ to follow .NET
14 naming conventions (as reported by FxCop).
16 2005-11-01 Jonathan Pryor <jonpryor@vt.edu>
18 * UnixDirectoryInfo.cs, UnixDriveInfo.cs, UnixEnvironment.cs,
19 UnixFileSystemInfo.cs, UnixGroupInfo.cs, UnixProcess.cs, UnixUserInfoc.cs:
20 Obsolete statements now specify in what way the return type will change.
21 * IncludeAttribute.cs: Obsoleted. It's an error to use it now.
23 2005-11-01 Jonathan Pryor <jonpryor@vt.edu>
25 * FileAccessPattern.cs: Change enumeration names to match Robert Love's more
26 sensible names from his FileAdvise class used in Beagle
27 (UseSoon --> PreLoad, WillNotUse --> FlushCache).
28 * FileHandleOperations.cs: Added; contains AdviseFileAccessPattern()
29 (moved from UnixFile.cs).
30 * UnixDirectory.cs: Obsolete the class; use UnixDirectoryInfo instead.
31 * UnixDirectoryInfo.cs: Add GetCurrentDirectory(), SetCurrentDirectory().
32 * UnixFile.cs: Obsolete the class; use UnixFileInfo, FileHandleOperations,
34 * UnixFileSystemInfo.cs: Add ToStat() method.
35 * UnixGroup.cs: Obsolete the class; use UnixGroupInfo instead.
36 * UnixGroupInfo.cs: Obsolete & Replace constructor, add GetMemberNames(),
38 * UnixPipes.cs: Added (type moved from UnixFile.cs).
39 * UnixStream.cs: AdviseFileAccessPattern() uses FileHandleOperations now.
40 * UnixSymbolicLinkInfo.cs: Implement TryReadLink() to avoid constant buffer
41 re-sizing. Stevens states that the file size of the symlink is the number
42 of bytes needed to hold the symlink, so this should be faster.
43 * UnixUser.cs: Obsolete the class; use UnixUserInfo instead.
44 * UnixUserInfo.cs: Obsolete & Replace constructor; add useful static members
45 from UnixUser such as GetLoginName(), GetLocalUsers(), etc.
47 2005-10-27 Jonathan Pryor <jonpryor@vt.edu>
49 * UnixEnvironment.cs: Add RealUser, RealGroup, EffectiveUser, EffectiveGroup
50 properties; [Obsolete] necessary methods and provide replacements.
51 * UnixStream.cs: Add OwnerUser(Id), OwnerGroup(Id) properties;
52 improve Stat handling.
54 2005-10-26 Jonathan Pryor <jonpryor@vt.edu>
56 * UnixEncoding.cs: Change EscapeByte to 0x0000, as suggested by Michal
58 * UnixPath.cs: Remove '\0' from InvalidPathChars, since U+0000 is now used
59 as the path escape character for marshaling purposes.
61 2005-10-26 Jonathan Pryor <jonpryor@vt.edu>
63 * UnixMarshal.cs: Obsolete heap-related methods to have a Heap suffix
64 (AllocHeap, FreeHeap, etc.), and change StringToAlloc() to be
65 StringToHeap(). This creates a stronger name association between related
68 2005-10-26 Jonathan Pryor <jonpryor@vt.edu>
70 * UnixIOException.cs: Add (string) and (string, Exception) constructors to
71 silence FxCop; re-work logic so we lookup the error string at construction
72 time and use this as the message for the base class.
74 2005-10-25 Jonathan Pryor <jonpryor@vt.edu>
76 * Stdlib.cs, Syscall.cs: Filenames need to be marshaled through the
77 FileNameMarshaler, which will encode/decode filenames with UnixEncoding.
78 * UnixEncoding.cs: Added (copied from
79 ../../corlib/System.Text/UTF8Encoding.cs); a hack to permit handling of
80 arbitrarily encoded filenames. It attempts to decode a byte[] array as
81 UTF-8, and if the decode fails it prefixes each byte with
82 UnixEncoding.EscapeByte (\uFFFF).
83 * UnixMarshal.cs: Use UnixEncoding as the default encoding, and special-case
84 UnixEncoding to use Stdlib.strlen() for native string lengths.
86 2005-10-21 Jonathan Pryor <jonpryor@vt.edu>
88 * FileAccessPattern.cs: Added
89 * UnixFile.cs, UnixStream.cs: Deprecate all the Advise* methods (lots!)
90 and replace with 6 methods which take a FileAccessPattern enum.
92 2005-10-19 Jonathan Pryor <jonpryor@vt.edu>
94 * FileAccessPermissions.cs, FileSpecialAttributes.cs, FileTypes.cs: Added.
95 * UnixFileSystemInfo.cs, UnixStream.cs: Replace the old Permission property
96 with 4 new properties: Protection (for the Native.FilePermissions value),
97 FileAccessPermissions (for rwxrwxrwx info), FileSpecialAttributes (for
98 set-user-id, set-group-id, sticky), and FileTypes (directory, socket...).
99 The new enumeration types have nicer CLS-compliant names.
101 2005-10-17 Jonathan Pryor <jonpryor@vt.edu>
103 * UnixMarshal.cs: Fix GetIntXxBufferLength to require fewer
104 Marshal.ReadIntXx() calls; Fix PtrToString so that
105 ``"foo" == PtrToString (StringToAlloc("foo",enc),enc)'' is true for
108 2005-10-17 Jonathan Pryor <jonpryor@vt.edu>
110 * UnixFileSystemInfo.cs: Add OwnerUserId and OwnerGroupId properties.
112 2005-10-17 Jonathan Pryor <jonpryor@vt.edu>
114 * UnixDriveInfo.cs, UnixEnvironment.cs, UnixFile.cs, UnixFileSystemInfo.cs,
115 UnixGroup.cs, UnixStream.cs, UnixUser.cs: Don't use SetLastError(), since
116 it's use is (1) incorrect, and (2) will be going away with the move to
117 Mono.Unix.Native.Syscall. Instead use the Native.Syscall.* APIs which
120 2005-10-17 Jonathan Pryor <jonpryor@vt.edu>
122 * UnixGroup.cs, UnixGroupInfo.cs, UnixFile.cs, UnixFileSystemInfo.cs,
123 UnixStream.cs, UnixSymbolicLinkInfo.cs, UnixUser.cs, UnixUserInfo.cs:
124 Start migrating uid/gid to long (from uint) for CLS compliance.
125 (Full migration must wait 'til after the next release as this would
126 require changes to existing members.)
127 * UnixEnvironment.cs: Above, and add RealUserId/RealGroupId and
128 EffectiveUserId/EffectiveGroupId.
130 2005-10-14 Jonathan Pryor <jonpryor@vt.edu>
132 * Catalog.cs: Create a constructor and mark it [Obsolete]. It will be made
133 private after the next release.
134 * UnixFile.cs, UnixStream.cs: Deal with Mono.Unix.Native type name changes.
135 * UnixFileSystemInfo.cs: [Obsolete] more members; Deal with Mono.Unix.Native
137 * Syscall.cs: Create maps for PathConf, SysConf, ConfStr again; fpathconf(),
138 pathconf(), and sysconf() should call Native.Syscall since the
139 MonoPosixHelper.so helpers have changed.
141 2005-10-13 Jonathan Pryor <jonpryor@vt.edu>
143 * UnixMarshal.cs: More/better StringToAlloc/PtrToString which take a
144 System.Text.Encoding instance for proper string marshaling.
145 - PtrToString(string,Encoding) is particularly tricky due to variable
147 - Fix StringToAlloc so that it works properly with UTF-16 encodings
148 (we need a terminating null 16-bit word, not a null byte).
149 - StringToAlloc overload for doing substrings.
151 2005-10-12 Jonathan Pryor <jonpryor@vt.edu>
153 * UnixStream.cs: Check for EROFS and EINVAL in Flush(). Snorp was getting
154 an exception when he created a UnixStream around a socket, because
155 sockets can't be flushed. It should be acceptable to create a UnixStream
156 around a socket, so don't throw an exception in this scenario.
158 2005-10-06 Jonathan Pryor <jonpryor@vt.edu>
160 * UnixDirectory.cs, UnixDirectoryInfo.cs UnixFile.cs, UnixFileSystemInfo.cs,
161 UnixGroupInfo.cs, UnixIOException.cs, UnixStream.cs, UnixUserInfo.cs:
162 API Review: Obsolete appropriate members and add appropriate overloads for
163 pending move to Mono.Unix.Native types.
164 * UnixMarshal.cs: API Review; add StringToAlloc().
166 2005-09-26 Jonathan Pryor <jonpryor@vt.edu>
168 * UnixFileSystemInfo.cs: Exists shouldn't use access(2), as (1) Exists isn't
169 virtual, and (2) access(2) errors if you try to access(2) a symlink which
170 points nowhere. Use (l)stat(2) instead, via GetFileStatus(), as this lets
171 UnixSymbolicLinkInfo behave properly.
172 * UnixSymbolicLinkInfo.cs: The Contents property should return null if the
173 symlink target doesn't exist.
175 2005-09-20 Jonathan Pryor <jonpryor@vt.edu>
177 * Syscall.cs: Add [Map] to AccessMode and MmapProt, as the Mono.Unix.Native
178 replacements go by different names (AccessModes, MmapProts), but we need
179 to continue generating the mapping code for these types (backward compat).
181 2005-09-20 Jonathan Pryor <jonpryor@vt.edu>
183 * CdeclFunction.cs: [Obsolete]d by Mono.Unix.Native.CdeclFunction.
184 * make-map.cs: Remove.
185 * Stdlib.cs: [Obsolete] the types; use the Mono.Unix.Native.* types instead.
186 * StdioFileStream.cs: Add GC.KeepAlive statements to prevent premature GC's
188 * Syscall.cs: Remove [Map] attribute from all types; [CLSCompliant(false)]
189 work; [Obsolete] all types and suggest using the Mono.Unix.Native.*
190 replacements; remove [IncludeAttribute] -- superseded by
191 Mono.Unix.Native/Syscall.cs's [HeaderAttribte] for CLS compliance.
192 * UnixConvert.cs: [Obsolete]d by Mono.Unix.Native.NativeConvert.
193 * UnixDirectory.cs, UnixDriveInfo.cs, UnixEnvironment.cs,
194 UnixGroup.cs, UnixGroupInfo.cs,
195 UnixSymbolicLinkInfo.cs, UnixUser.cs, UnixUserInfo.cs:
196 Add [CLSCompliant(false)] as necessary.
197 * UnixFile.cs, UnixDirectory.cs, UnixFileInfo.cs, UnixFileSystemInfo.cs:
198 [CLSCompliant(false)], addition of method overloads for [Obsolete]d types,
199 warn about changing return types.
200 * UnixProcess.cs, UnixStream.cs: Add [CLSCompliant(false)] as necessary,
201 and warn about changing property types.
203 2005-09-02 Jonathan Pryor <jonpryor@vt.edu>
205 * Stdlib.cs: Cache delegates passed to Stdlib.signal() so that they survive
206 garbage collections. Delegates can be removed by calling Stdlib.signal()
207 again with one of the Stdlib.SIG_* values (or the original return value of
209 * UnixUser.cs, UnixGroup.cs, UnixEnvironment.cs: Clarify "Id" (int) vs.
210 "Name" (string) differences by always using a Id or Name suffix.
212 2005-07-01 Daniel Drake <dsd@gentoo.org>
214 * Syscall.cs: The entire extended attribute API now goes through MPH, to
215 be shared between both Linux's and FreeBSD's similar EA implementations.
217 2005-06-29 Miguel de Icaza <miguel@ximian.com>
219 * StdioFileStream.cs: Only flush if we do not own the handle, as
220 fclose does a flush internally.
222 2005-06-29 Jonathan Pryor <jonpryor@vt.edu>
224 * UnixEnvironment: Add User, Login properties.
225 * Syscall.cs: Add locking around cuserid, crypt, encrypt, getlogin.
227 2005-06-29 Jonathan Pryor <jonpryor@vt.edu>
229 * Syscall.cs: SyslogFacility shouldn't be [Flags] either. Sigh.
230 Thanks to Vorobiev Maksim for pointing this out.
231 * make-map.cs: Don't generate conversion code for [Obsolete] enum members.
232 This assumes that (1) the enum member's value is invalid, or (2) a
233 corrected member with the same value exists. This fix allows us to
234 obsolete invalid members (instead of removing them) without screwing up
235 the generated code -- consider LOG_USRE, the mis-spelling of LOG_USER.
236 Since SyslogFacility was (incorrectly) a [Flags] enum, since both LOG_USER
237 and LOG_USRE had the same value, we'd get a EINVAL error trying to convert
238 a valid value, since LOG_USRE would exist, would be checked for, and the
239 check would succeed (since it had the same value as LOG_USER).
240 This change allows us to be slightly more permissive with versioning.
242 2005-06-28 Jonathan Pryor <jonpryor@vt.edu>
244 * Syscall.cs: correct value of LOG_CRON (it shouldn't be identical to
245 LOG_UUCP). SyslogLevel shouldn't have [Flags]. Move LOG_USER to be
246 before LOG_USRE so that the generated map code doesn't return EINVAL when
247 LOG_USER is specified.
249 2005-06-15 Jonathan Pryor <jonpryor@vt.edu>
251 * Syscall.cs: s/LOG_USRE/LOG_USER/. Fixes #75274.
252 Thanks to Martin Honermeyer.
254 2005-06-09 Jonathan Pryor <jonpryor@vt.edu>
256 * make-map.cs: Look for [Obsolete] members, and mark the UnixConvert
257 conversion functions with the same [Obsolete] message. This should permit
258 more graceful deprecation of enumerations in the future (rather than just
261 2005-06-08 Jonathan Pryor <jonpryor@vt.edu>
263 * Syscall.cs: Add execvp(2). (This should have been added with the other
264 exec(2) additions...).
266 2005-06-08 Jonathan Pryor <jonpryor@vt.edu>
268 * Syscall.cs: Update comment with correct exception type.
269 * UnixConvert.cs: Rename ToFilePermissions(string) to
270 FromOctalPermissionString; Add ToOctalPermissionString,
271 FromUnixPermissionString, ToUnixPermissionString.
272 * UnixMarshal.cs: Remove ErrorMarshal.HaveStrerror_r and
273 UnixMarshal.IsErrorDescriptionThreadSafe. strerror(3) is now thread-safe
274 (from managed code, at least). Update comment.
276 2005-06-07 Jonathan Pryor <jonpryor@vt.edu>
278 * UnixFileSystemInfo.cs: Don't use lstat(2), use stat(2). This fits with
279 expectations better -- if you create a UnixFileInfo() on a symlink, you
280 want to get the target's information, not the symlink's info. Add
281 GetFileStatus so UnixSymbolicLinkInfo can override this behavior.
282 * UnixSymbolicLinkInfo.cs: Implement GetFileStatus() (which calls lstat(2)).
284 2005-06-07 Jonathan Pryor <jonpryor@vt.edu>
286 * Syscall.cs: Document naming conventions.
288 2005-06-05 Jonathan Pryor <jonpryor@vt.edu>
290 * make-map.cs: Change automatic "ifdef HAVE_<header>" support prefix to
291 "ah:" from ">". I hadn't known about ">", and "ah:" is (somewhat) more
293 * Syscall.cs: Change IncludeAttribute to put all headers/defines one/line.
294 It's easier to read this way. Add "ah:sys/xattr.h" to the headers.
296 2005-06-03 Jonathan Pryor <jonpryor@vt.edu>
298 * Stdlib.cs: Add sanity checking to snprintf(3) to avoid buffer overflows.
300 2005-06-02 Jonathan Pryor <jonpryor@vt.edu>
302 * StdioFileStream.cs: Remove FilePosition property & replace with
303 SaveFilePosition/RestoreFilePosition methods. Since FilePosition has a
304 finalizer, it's not right to have implicitly created instances.
306 - FilePosition: GC.SuppressFinalize() should be last in Dispose()
307 (following .NET guidelines).
308 - Syscall: Add locking around functions most likely to be thread unsafe.
309 This should provide some level of thread-safety to managed code.
310 * Syscall.cs: Add locking around functions most likely to be thread unsafe;
311 add mkstemp(3) export.
312 * UnixEnvironment.cs: GetUserShells should be atomic (from managed code).
313 * UnixGroup.cs: GetLocalGroups should be atomic (from managed code).
314 * UnixGroupInfo.cs: Add ToGroup() method to retrieve underlying Group info.
315 * UnixUser.cs: GetLocalUsers should be atomic (from managed code).
316 * UnixUserInfo.cs: Add ToPasswd () method to retrieve underlying Passwd info.
317 * UnixDriveInfo.cs: GetDrives should be atomic (from managed code).
319 2005-05-31 Jonathan Pryor <jonpryor@vt.edu>
321 * Stdlib.cs: Add comment for atexit(3) so I don't try to add it.
322 * Syscall.cs: Add fcntl(2) overload which takes DirectoryNotifyFlags (so
323 that *something* accepts a DirectoryNotifyFlags); Fix IncludeAttribute
324 header files (">sys/poll.h" doesn't exist);
325 Add additional <sys/mman.h> functions mmap, munmap, msync, mlock, munlock,
326 mlockall, munlockall, mremap, mincore, remap_file_pages.
327 * UnixConvert.cs: Add conversion functions for MmapFlags, MmapProt, MsyncFlags,
328 MlockallFlags, MremapFlags.
330 2005-05-31 Jonathan Pryor <jonpryor@vt.edu>
332 * Syscall.cs, UnixConvert.cs: Rename LockFlags to LockfCommand. This is a more
333 consistent naming, and it's more correct (they weren't flags in the first place).
335 2005-05-18 Jonathan Pryor <jonpryor@vt.edu>
337 * Stdlib.cs: Correct Mono_Posix_Stdlib_InvokeSignalHandler export.
339 2005-05-18 Jonathan Pryor <jonpryor@vt.edu>
341 * make-map.cs: Process the Mono.Posix namespace as well as Mono.Unix; add
342 mapping for Boolean => int for native type conversion.
344 2005-05-18 Jonathan Pryor <jonpryor@vt.edu>
346 * make-map.cs: Add a MphPrototypeFileGenerator, which looks for DllImport
347 methods across all types and generates a C header file declaration for
348 those methods. This allows us to ensure consistency between
349 Mono.Posix.dll and MonoPosixHelper.so. Rename WrapperFileGenerator to
350 ConvertFileGenerator (it generates UnixConvert).
351 * MapAttribute.cs, IncludeAttribute.cs: Make these internal -- there's no
352 reason for external users to even know these exist.
353 * StdioFileStream.cs: Move GC.SuppressFinalize call to be last Dispose()
354 call. This follows current design guidelines, and allows an exception to
355 be thrown from Dispose() without un-registering the finalizer.
356 * Syscall.cs: Change method declarations to match MonoPosixHelper, etc.
357 - posix_fallocate(P) takes a size_t
358 - mis-spelled settimeofday(2), sethostname(2)
359 - exec(2) can be public; it's safe to call
360 - change lseek(2) so int's are passed to MonoPosixHelper.so, not shorts
361 - We can't allow two incompatible prototypes to exist (since C allows
362 only one prototype, and we're cross-checking prototypes now). Change
363 utime(2) so only one prototype is needed.
364 * UnixMarshal.cs: ErrorMarshal.ErrorTranslator and ErrorMarshal.Translate
365 shouldn't be public; make them internal.
366 * UnixStream.cs: Remove `unsafe` code block when a "safe" alternative works;
367 Close() should also call GC.SuppressFinalize.
369 2005-05-12 Jonathan Pryor <jonpryor@vt.edu>
371 * Syscall.cs: The Statvfs structure should contain a MountFlags enumeration,
372 not a ulong (we can "safely" do this since POSIX defines some values for
373 f_flag, so we should be kind and expose them).
374 * UnixConvert.cs: Add MountFlags conversion functions.
376 2005-05-02 Joe Shaw <joeshaw@novell.com>
378 * UnixListener.cs (Init): Remove the call to Cleanup() and the
379 method itself, which was not supposed to be here. We try to
380 connect to the socket if it exists instead of deleting it
383 2005-04-30 Ben Maurer <bmaurer@ximian.com>
385 * Stdlib.cs: Comment out usage of `UnmanagedFunctionPointer'. It
386 isn't supported in the runtime -- it throws an assert -- so better
387 not to use it at all for now.
389 2005-04-29 Jonathan Pryor <jonpryor@vt.edu>
391 * UnixConvert.cs: Fix time_t -> DateTime conversions. time_t should be
392 assumed to be in the local time zone, so don't mess with UTC shifts.
393 This allows Mono.Unix to produce sane output (e.g. identical to ls(1) or
394 stat(1), instead of several hours different).
396 2005-04-29 Jonathan Pryor <jonpryor@vt.edu>
398 * Stdlib.cs: Make FilePosition slightly more useful by providing a
399 ToString() override which dumps the fpos_t structure contents into a
400 hex string. Add Equals(), GetHashCode(), operator==, and operator!=
401 so FilePosition behaves like a value type.
403 2005-04-21 Gonzalo Paniagua Javier <gonzalo@ximian.com>
406 * UnixListener.cs: TcpListener/TcpClient clones from Jow Shaw.
408 2005-04-21 Gonzalo Paniagua Javier <gonzalo@ximian.com>
410 * Mono.Posix.dll.sources: added UnixListener and UnixClient from Joe
413 2005-04-21 Gonzalo Paniagua Javier <gonzalo@ximian.com>
415 * UnixEndPoint.cs: fix from Mono.Posix.
417 2005-04-20 Jonathan Pryor <jonpryor@vt.edu>
419 * Syscall.cs: Make all fork(2) and exec(2) functions `private`. It
420 currently isn't safe to call these under *any* circumstances. See also
421 68141, and this pertinent quote from Butenhof's
422 "Programming with POSIX Threads", p197, s6.1:
424 "When a threaded process calls fork to create a child process,
425 Pthreads specifies that only the thread calling fork exists in the
426 child. ... Pthreads does not 'terminate' the other threads in a forked
427 process...They simply cease to exist. ... This is not a problem if
428 the child process is about to call exec to run a new program, but if
429 you use fork to clone a threaded program, beware that you may lose
430 access to memory, especially heap memory stored only as
431 thread-specific data values."
433 Since P/Invoke currently requires using thread local storage, once you
434 fork(2) you won't be able to invoke exec(2) from managed code (since that
435 would require a P/Invoke transition to call exec(2), which would require
436 TLS, which doesn't exist in the new process).
438 This can only be fixed by removing the TLS dependency on P/Invoke, which
439 isn't a priority (and may not be possible).
441 The workaround is to create a C function which does your fork(2)/exec(2)
442 (and any other functions such as daemon(3)) on your behalf, and P/Invoke
443 to call this C function.
445 2005-04-18 Jonathan Pryor <jonpryor@vt.edu>
447 * Syscall.cs: Update comment specifying which functions belong in Syscall.
448 * UnixConvert.cs: Add XattrFlags conversion functions.
449 * UnixMarshal.cs: Remove warning about self-assignment.
451 2005-04-16 Daniel Drake <dsd@gentoo.org>
453 * Syscall.cs: Add bindings for extended attribute manipulation
455 2005-04-05 Miguel de Icaza <miguel@novell.com>
457 * Syscall.cs: Set entry point for sys_syslog to be syslog.
458 Include the syslog.h header in the generated map so that we
459 actually do the mapping.
461 2005-03-28 Jonathan Pryor <jonpryor@vt.edu>
463 * UnixConvert.cs: Add ToFopenMode() methods, which convert FileMode/FileAccess
464 into an fopen(3) mode string. ToOpenFlags() should throw
465 ArgumentOutOfRangeException for argument violations.
466 * StdioFileStream.cs: Add constructor overloads accepting filename and
467 FileMode/FileAccess overloads; Compatibility fixes with regression tests;
468 remove IDisposable implementation since System.IO.Stream already
469 implements it (which calls Close() for us).
471 2005-03-17 Jonathan Pryor <jonpryor@vt.edu>
473 * Stdlib.cs: Move Errno-related functionality into Stdlib from Syscall,
474 since (1) errno is part of C89, and (2) StdioFileStream will need it, and
475 StdioFileStream shouldn't use Syscall. Add [UnmanagedFunctionPointer]
476 attribute to SignalHandler for .NET 2.0 (since signal handlers use C
477 calling convention, not Stdcall).
478 * Syscall.cs: Move Errno-related functionality into Stdlib.
479 * UnixMarshal.cs: Use ERANGE not EPERM when figuring out appropriate
480 translator, since ERANGE is part of C99 and EPERM isn't. Use Stdlib
481 instead of Syscall for Errno-related functionality.
483 2005-02-02 Jonathan Pryor <jonpryor@vt.edu>
485 * UnixFile.cs: Cope with changes in UnixStream.
486 * UnixStream.cs: Change FileDescriptor property to Handle for consistency.
487 * StdioFileStream.cs: Change FileStream property to Handle for consistency.
489 2005-02-02 Jonathan Pryor <jonpryor@vt.edu>
491 * Syscall.cs: Remove public sys_ methods. Some were public by mistake, and
492 others so that users could manually marshal strings if desired. Manually
493 marshaling strings shouldn't be necessary, though, so remove them too.
495 2005-02-02 Jonathan Pryor <jonpryor@vt.edu>
497 * StdioFileStream.cs: Fix Length property to actually return the size of the
498 file, not the # of bytes from the current position to EOF. Oops.
500 2005-01-31 Jonathan Pryor <jonpryor@vt.edu>
502 * Stdlib.cs: Import "msvcrt", not "libc". These members are part of the
503 ANSI C standard, and thus should be present on Windows via msvcrt.dll
504 (except snprintf, until they catch up to C99). Change the calling
505 convention of all functions to Cdecl, as the .NET default is Stdcall.
506 Changing the calling convention isn't needed in Syscall, as it can only be
507 run on Unix platforms anyway, where the default is Cdecl.
508 * Syscall.cs: Add LIBC member that points to the real "libc"; we can't use
509 the imported definition from Stdlib as "msvcrt" doesn't exist on Unix.
511 2005-01-29 Jonathan Pryor <jonpryor@vt.edu>
513 * Stdlib.cs: sys_* functions shouldn't be public.
515 2005-01-13 Jonathan Pryor <jonpryor@vt.edu>
517 * make-map.cs: libMonoPosixHelper exports Mono_Posix prefixes, not Mono_Unix
518 prefixes, so change the type and namespace to generate compatible code.
519 * Syscall.cs: Change OpenFlags values so they match the Linux values.
521 2005-01-13 Jonathan Pryor <jonpryor@vt.edu>
523 * Stdlib.cs: Use Stdlib.LIBC instead of "libc".
524 * StdioFileStream.cs: Add FilePosition property (not that I expect anyone to
525 use it) and Rewind() method.
527 2005-01-05 Jonathan Pryor <jonpryor@vt.edu>
529 * StdioFileStream.cs: Added; System.IO.Stream wrapper for C FILE struct.
530 * Stdlib.cs: Correct visibility of ftell().
532 2005-01-05 Jonathan Pryor <jonpryor@vt.edu>
534 * Stdlib.cs: Re-order declarations to match the order used in the
535 C99 Standard Annex B; Complete <stdio.h> exports (except for those not
536 worth supporting); Add non-"unsafe" versions of fread(3), fwrite(3) and
537 add some rudimentary buffer-overflow checking; Add <stdlib.h> exports such
538 as getenv(3), exit(3), rand(3), EXIT_SUCCESS, RAND_MAX, etc.
540 2005-01-03 Jonathan Pryor <jonpryor@vt.edu>
542 * Syscall.cs: Update endfsent() and setfsent() declarations, as these must
543 now be implemented in MonoPosixHelper.
545 2005-01-01 Jonathan Pryor <jonpryor@vt.edu>
547 * Stdlib.cs, Syscall.cs: Minimize duplicate declarations of
548 "MonoPosixHelper" for use in DllImport statements.
550 2005-01-01 Jonathan Pryor <jonpryor@vt.edu>
552 * Stdlib.cs: Don't use C# v2 features; fixes build under CSC.EXE.
554 2004-12-30 Jonathan Pryor <jonpryor@vt.edu>
556 * Stdlib.cs: On miguel's suggestion, rename Sighandler_t to SignalHandler.
558 2004-12-30 Jonathan Pryor <jonpryor@vt.edu>
560 * Stdlib.cs: Implement all C89 <stdio.h> functions except for the scanf(3)
561 family. These are too dangerous to expose.
563 2004-12-30 Jonathan Pryor <jonpryor@vt.edu>
565 * CdeclFunctions.cs: Remove warning about unused variable.
566 * Stdlib.cs: Make signal(2) sane and (hopefully) complete.
567 * Syscall.cs: Fix cuserid Obsolete message to reference correct class name.
568 * UnixProcess.cs: Remove warning about unused variable.
569 * UnixMarshal.cs: Remove warnings about unused variables.
571 2004-12-29 Jonathan Pryor <jonpryor@vt.edu>
573 * UnixPath.cs: Add ReadSymbolicLink(), which takes an intelligent approach
574 to reading symlinks (since their contents may be any size, we grow the
575 buffer dynamically to fit them all, instead of assuming a maximum size).
576 * UnixSymbolicLinkInfo.cs: Remove MaxContentsSize.
578 2004-12-29 Jonathan Pryor <jonpryor@vt.edu>
580 * UnixPath.cs: Add check for when symlink points to a full path name.
582 2004-12-29 Jonathan Pryor <jonpryor@vt.edu>
584 * Syscall.cs: Fix Object.Equals implementations.
585 * UnixPath.cs: New & improved, with Testing! GetRealPath() is changed so
586 that it doesn't walk the entire path looking for symlinks, it just reads
587 the leaf. GetCompletRealPath() walks the entire path resolving symlinks.
588 GetCanonicalPath() added, which "cleans up" a path (removing extraneous
589 "." and ".." entries).
590 * UnixSymbolicLinkInfo.cs: Rename ContentsLength -> MaxContentsSize.
592 2004-12-28 Jonathan Pryor <jonpryor@vt.edu>
594 * UnixFileSystemInfo.cs: Add a link(2) wrapper, CreateLink(). Strictly
595 speaking it's only "safe" to do this on files, but an exception will be
596 returned if the user tries to hard link directories (because of EPERM),
597 unless the user is root, in which case it should be allowed anyway...
599 2004-12-28 Jonathan Pryor <jonpryor@vt.edu>
601 * CdeclFunctions.cs: Correct the comments for AMD64
602 * UnixDirectoryInfo.cs: override Name; add Parent & Root properties;
603 Correct Path usage (s/Path/FullPath/g).
604 * UnixDriveInfo.cs: Added. Based on .NET 2.0 System.IO.DriveInfo docs,
605 provides statvfs(2) and getfsfile(3) information about a mounted volume.
606 GetDrives() wraps getfsent(3), thus parsing /etc/fstab.
607 * UnixFile.cs: Use UnixConver.ToOpenFlags, deleting the local version.
608 * UnixFileInfo.cs: Use UnixConver.ToOpenFlags, deleting the local version;
609 override Name; add DirectoryName and Directory properties;
610 * UnixFileSystemInfo.cs: Make more .NET-like, using FullPath and
611 OriginalPath protected members, abstract Name property; Add
612 CreateSymbolicLink; Remove ReadLink (it's now
613 UnixSymbolicLinkInfo.Contents); Use lstat(2) for Create(string), so we
614 properly detect Symbolic Links.
615 * UnixPath.cs: Added; Path manipulation utility functions.
616 * UnixSymbolicLinkInfo.cs:
618 - override new abstract member Name;
619 - rename ReadLink to ContentsPath (and Contents) properties
620 (why "Contents"? Because readlink(2) says "readlink places the
621 contents of the symbolic link in the buffer...")
622 - Add CreateSymbolicLinkTo(), which creates a symlink to the specified
625 2004-12-28 Jonathan Pryor <jonpryor@vt.edu>
627 * Stdlib.cs: Add syslog(3) to XPrintfFunctions; Add additional printf(3)
628 and fprintf(3) overload which properly escape the format string
629 (by using "%s" as the format for the user-supplied message).
630 * Syscall.cs: Add #regions for enummerations, structures, classes; Wrap
631 syslog(3) and related enumerations; fix operator!= on Dirent, Group;
632 wrap {f}statvfs(2); wrap <fstab.h> entries (getfsent(3), etc.).
633 * UnixConvert.cs: Add Syslog-releated enumeration translation functions;
634 Move ToOpenFlags here from UnixFile and UnixFileInfo.
635 * UnixMarshal.cs: Missing P/Invoke methods throw
636 EntryPointNotFoundException, not MissingMethodException; add
637 EscapeFormatString, which escapes printf-style format strings so that they
638 can be safely handed off to native code (avoiding stack overflow, etc);
639 make CreateExceptionForError internal.
641 2004-12-15 Jonathan Pryor <jonpryor@vt.edu>
643 * Stdlib.cs: Add more <stdio.h> wrappers, such as fread(3) and fwrite(3).
644 These will be useful in implementing System.IO.Stream subclass for
645 reading/writing to a FILE*. Fix a typo in the realloc(3) DllImport.
646 * Syscall.cs: Fix the sys_kill and sys_crypt declarations.
647 * CdeclFunction.cs: Document calling convention problems on AMD64.
649 2004-11-18 Jonathan Pryor <jonpryor@vt.edu>
651 * CdeclFunction.cs: Added.
652 * Stdlib.cs: Re-add printf(3) and fprintf(3). They may not be portable (the
653 jury is still out on that; the AMD64 SysV ABI looks like it should be
654 portable to AMD64 to my eyes), but they will work on *some* platforms, so
655 we should permit it. The new implementation takes a page out of
656 cocoa-sharp: use System.Reflection.Emit to generate a P/Invoke method at
657 runtime to invoke printf(3) or fprintf(3). This way, we can export a
658 params signature to C# code, permitting natural usage such as:
659 Stdlib.printf ("Hello, %s world! (%i)\n", "silly", 42);
660 * Syscall.cs: Mark which headers are complete, which functions still need
661 wrapping (for headers which have anything done to them), add #region
662 blocks for each header;
663 export mkfifo(3), fexecve(), getppid(2), setlogin(); fix sleep(3) export.
664 * UnixEnvironment.cs: Export a friendly getppid(2) wrapper.
665 GetParentProcessId isn't in UnixProcess as there's no way (that I know of)
666 to get the Parent's Parent, so it can't be a class member, and exposing it
667 as a static member of UnixProcess doesn't make sense to me, as it isn't
668 general. Added GetUserShells().
669 * UnixProcess.cs: Change constructor to internal, so it can be used from
672 2004-11-16 Jonathan Pryor <jonpryor@vt.edu>
674 * Stdlib.cs: Remove printf(3) and fprintf(3). These are vararg/CDECL
675 functions, and it's not portable to call them in this manner.
676 (It's not portable because some architectures, such as AMD64, use a
677 "cookie" as part of the vararg calling sequence to help reduce buffer
678 overflow exploits. Trying to call vararg functions as if they were an
679 overloaded function will not properly set this hardware cookie, resulting
680 in a hardware exception. Talk to lupus for more information.)
682 2004-11-16 Jonathan Pryor <jonpryor@vt.edu>
684 * Syscall.cs, UnixConvert.cs: Remove mount- and umount-related
685 functionality. Mount/umount is inherently non-portable (see the C code
686 for mount/umount), and trying to provide a consistent interface is
687 impossible. If you need mount/umount support, use the command-line
688 programs mount(1) and umount(1).
690 2004-11-16 Jonathan Pryor <jonpryor@vt.edu>
692 + Lots o' Renames, as the namespace changed.
693 * PosixConvert.cs: Moved to UnixConvert.cs:
694 * PosixDirectory.cs: Moved to UnixDirectory.cs:
695 * PosixEnvironment.cs: Moved to UnixEnvironment.cs:
696 * PosixDirectoryInfo.cs: Moved to UnixDirectoryInfo.cs:
697 * PosixFile.cs: Moved to UnixFile.cs:
698 * PosixFileInfo.cs: Moved to UnixFileInfo.cs:
699 * PosixFileSystemInfo.cs: Moved to UnixFileSystemInfo.cs:
700 * PosixGroup.cs: Moved to UnixGroup.cs:
701 * PosixGroupInfo.cs: Moved to UnixGroupInfo.cs:
702 * PosixIOException.cs: Moved to UnixIOException.cs:
703 * PosixMarshal.cs: Moved to UnixMarshal.cs:
704 * PosixProcess.cs: Moved to UnixProcess.cs:
705 * PosixStream.cs: Moved to UnixStream.cs:
706 * PosixSymbolicLinkInfo.cs: Moved to UnixSymbolicLinkInfo.cs:
707 * PosixUser.cs: Moved to UnixUser.cs:
708 * PosixUserInfo.cs: Moved to UnixUserInfo.cs:
709 * Catalog.cs, IncludeAttribute.cs, MapAttribute.cs, PeerCred.cs, Stdlib.cs,
710 Syscall.cs, UnixConvert.cs, UnixDirectory.cs, UnixDirectoryInfo.cs,
711 UnixEndPoint.cs, UnixEnvironment.cs, UnixFile.cs, UnixFileInfo.cs,
712 UnixFileSystemInfo.cs, UnixGroup.cs, UnixGroupInfo.cs, UnixIOException.cs,
713 UnixMarshal.cs, UnixProcess.cs, UnixStream.cs, UnixSymbolicLinkInfo.cs,
714 UnixUser.cs, UnixUserInfo.cs: Deal with renamed classes/members.
716 2004-11-15 Jonathan Pryor <jonpryor@vt.edu>
718 * PosixUserInfo.cs: Make the PosixUserInfo(Passwd) constructor public;
719 override Object.GetHashCode and Object.Equals.
720 * PosixGroupInfo.cs: Make the PosixGroupInfo(Group) constructor public;
721 override Object.GetHashCode and Object.Equals.
722 * PosixIOException.cs: Use PosixMarshal.GetErrorDescription instead of
723 calling Syscall.strerror_r directly
724 * PosixMarshal.cs: Add GetErrorDescription. Strerror_r() isn't portable, so
725 GetErrorDescription() first tries strerror_r(), and if it fails falls back
728 - Seal the Dirent class. It has no virtual members, so there's no point
729 in it being non-sealed. Override Object.GetHashCode and Object.Equals.
730 - Seal the Group class. It has no virtual members, so there's no point
731 in it being non-sealed. Override Object.GetHashCode and Object.Equals.
732 Provide operator== and operator!=.
733 - Seal the Passwd class. It has no virtual members, so there's no point
734 in it being non-sealed. Override Object.GetHashCode and Object.Equals.
735 Provide operator== and operator!=.
736 - Remove strerror_r() convenience overload. This is now
737 PosixMarshal.GetErrorDescription().
739 2004-11-12 Jonathan Pryor <jonpryor@vt.edu>
741 * Syscall.cs: Export time-related functions (gettimeofday, settimeofday,
742 utime, utimes), mknod.
744 2004-11-07 Atsushi Enomoto <atsushi@ximian.com>
746 * PosixEnvironment.cs : csc build fix. see bug #69195.
747 * PosixStream.cs : csc build fix. see bug #69196.
749 2004-11-05 Jonathan Pryor <jonpryor@vt.edu>
751 * PosixConvert.cs: New file; conversion functions for Mono.Posix types.
752 * PosixDirectory.cs: New file; Friendly wrapper over directory information.
753 * PosixDirectoryInfo.cs: New file; Friendly wrapper over directory information.
754 * PosixEnvironment.cs: New file; Friendly wrapper over environment information.
755 * PosixFile.cs: New file; Friendly wrapper over file information.
756 * PosixFileInfo.cs: New file; Friendly wrapper over file information.
757 * PosixFileSystemInfo.cs: New file; Friendly wrapper over `stat'.
758 * PosixGroup.cs: New file; User Group-related functionality
759 * PosixGroupInfo.cs: New file; User Group-related functionality
760 * PosixIOException.cs: New file; Exception for POSIX-generated exceptions.
761 * PosixMarshal.cs: New file; utility functions for marshaling, etc.
762 * PosixProcess.cs: New file; Friendly wrapper over process information.
763 * PosixStream.cs: New file; Friendly wrapper over file descriptors.
764 * PosixSymbolicLinkInfo.cs: New file; Friendly wrapper over symbolic links.
765 * PosixUser.cs: New file; Friendly wrapper over user information.
766 * PosixUserInfo.cs: New file; Friendly wrapper over user information.
767 * Stdlib.cs: New file; C standard library exports.
768 * Syscall.cs: Effective re-write.
769 - Organize exports by header file
770 - add additional enumerations (Error for the E* error values, etc.)
771 - always explicitly specify enumeration underlying type
772 - Use a new wrapping infrastructure so that ABI-stable types are exported
773 - For example, size_t is exported as ulong, not IntPtr.
774 - Wrap more functions, and wrap them better (such as getpwnam).
775 - This release is NOT backward compatible. Many names are the same, and
776 hopefully they're still compatible, but no effort was made to maintain
777 compatibility. For example, FileMode was removed and replaced with
778 FilePermissions, to avoid a name conflict with System.IO.FileMode.
779 - Change umount() to use MonoPosixHelper: portability fix for Mac OS X.
780 * make-map.cs: Another effective re-write, to clean up the code, produce
781 better output, and produce more output. For example, most of
782 PosixConvert can be auto-generated, so it is (modulo version delays and
783 bootstrap issues). `map.c' is now conditional on all macros, and has
784 error checking for invalid/unsupported values.
786 2004-09-18 Jackson Harper <jackson@ximian.com>
788 * Syscall.cs: Add support for poll ().
790 2004-09-18 Jackson Harper <jackson@ximian.com>
792 * make-map.cs: Use field value not name for #defines.
794 2004-09-14 Loren Bandiera <lorenb@mmgsecurity.com>
796 * Syscall.cs: Added method for getpwnam which uses Passwd
798 * macros.c: Helper function for getpwnam
799 (In committing, Josh Tauberer also added getpwuid.)
801 2004-07-09 Dick Porter <dick@ximian.com>
803 * PeerCred.cs: Get the unix socket peer credentials.
805 2004-05-26 Miguel de Icaza <miguel@ximian.com>
807 * Syscall.cs: Do not let the runtime handle strings, as we do not
808 own those strings, we must transform the char * into a string
811 2004-05-03 Miguel de Icaza <miguel@ximian.com>
813 * Syscall.cs: Add symlink
815 2004-04-19 Miguel de Icaza <miguel@ximian.com>
817 * Syscall.cs: Use hex values for FileMode, since C# does not have
818 an octal integer mode.
820 2004-03-30 Joshua Tauberer <tauberer@for.net>
822 * Added readlink, strerror, opendir, readdir, closedir
823 * Added Mono.Posix.Stat.UnixToDateTime(long unixtime) --> DateTime
825 2004-03-11 Joshua Tauberer <tauberer@for.net>
827 * Syscall.cs: Removed argument to getgid that shouldn't be there.
828 Added getusername, getgroupname which wrap getpwuid, getgrgid
829 without dealing with pointers to structures.
830 Removed duplicate FileMode enum nested in Syscall class.
831 Added stat and lstat, which use StatMode enumeration
832 (like FileMode but nicer and complete) and Stat struct.
833 * macros.c: Helper functions for getpwuid, getgrgid, stat, lstat.
835 2004-01-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
837 * Syscall.cs: moved the assembly attribute to a proper place
839 * make-map.cs: use reflection to invoke the properties, as it
840 fails under MS runtime.
843 2004-01-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
845 * Syscall.cs: moved assembly attribute and added unsafe block to fix
846 the build on windows.
848 2003-11-11 Wojciech Polak <polak@gnu.org
850 * Syscall.cs: Applied patch from Wojciech Polak <polak@gnu.org> to
853 2003-05-16 Dick Porter <dick@ximian.com>
855 * UnixEndPoint.cs: New property to get and set the filename, like
856 the IPEndPoint has for the IP address. Also implement ToString().
858 Tue Apr 29 16:53:56 CEST 2003 Paolo Molaro <lupus@ximian.com>
860 * Syscall.cs: remove the unsafe mess.
862 2003-02-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
865 * UnixEndPoint.cs: first file.
