4 * UnixListener.cs: TcpListener/TcpClient clones from Jow Shaw.
6 2005-04-21 Gonzalo Paniagua Javier <gonzalo@ximian.com>
8 * Mono.Posix.dll.sources: added UnixListener and UnixClient from Joe
11 2005-04-21 Gonzalo Paniagua Javier <gonzalo@ximian.com>
13 * UnixEndPoint.cs: fix from Mono.Posix.
15 2005-04-20 Jonathan Pryor <jonpryor@vt.edu>
17 * Syscall.cs: Make all fork(2) and exec(2) functions `private`. It
18 currently isn't safe to call these under *any* circumstances. See also
19 68141, and this pertinent quote from Butenhof's
20 "Programming with POSIX Threads", p197, s6.1:
22 "When a threaded process calls fork to create a child process,
23 Pthreads specifies that only the thread calling fork exists in the
24 child. ... Pthreads does not 'terminate' the other threads in a forked
25 process...They simply cease to exist. ... This is not a problem if
26 the child process is about to call exec to run a new program, but if
27 you use fork to clone a threaded program, beware that you may lose
28 access to memory, especially heap memory stored only as
29 thread-specific data values."
31 Since P/Invoke currently requires using thread local storage, once you
32 fork(2) you won't be able to invoke exec(2) from managed code (since that
33 would require a P/Invoke transition to call exec(2), which would require
34 TLS, which doesn't exist in the new process).
36 This can only be fixed by removing the TLS dependency on P/Invoke, which
37 isn't a priority (and may not be possible).
39 The workaround is to create a C function which does your fork(2)/exec(2)
40 (and any other functions such as daemon(3)) on your behalf, and P/Invoke
41 to call this C function.
43 2005-04-18 Jonathan Pryor <jonpryor@vt.edu>
45 * Syscall.cs: Update comment specifying which functions belong in Syscall.
46 * UnixConvert.cs: Add XattrFlags conversion functions.
47 * UnixMarshal.cs: Remove warning about self-assignment.
49 2005-04-16 Daniel Drake <dsd@gentoo.org>
51 * Syscall.cs: Add bindings for extended attribute manipulation
53 2005-04-05 Miguel de Icaza <miguel@novell.com>
55 * Syscall.cs: Set entry point for sys_syslog to be syslog.
56 Include the syslog.h header in the generated map so that we
57 actually do the mapping.
59 2005-03-28 Jonathan Pryor <jonpryor@vt.edu>
61 * UnixConvert.cs: Add ToFopenMode() methods, which convert FileMode/FileAccess
62 into an fopen(3) mode string. ToOpenFlags() should throw
63 ArgumentOutOfRangeException for argument violations.
64 * StdioFileStream.cs: Add constructor overloads accepting filename and
65 FileMode/FileAccess overloads; Compatibility fixes with regression tests;
66 remove IDisposable implementation since System.IO.Stream already
67 implements it (which calls Close() for us).
69 2005-03-17 Jonathan Pryor <jonpryor@vt.edu>
71 * Stdlib.cs: Move Errno-related functionality into Stdlib from Syscall,
72 since (1) errno is part of C89, and (2) StdioFileStream will need it, and
73 StdioFileStream shouldn't use Syscall. Add [UnmanagedFunctionPointer]
74 attribute to SignalHandler for .NET 2.0 (since signal handlers use C
75 calling convention, not Stdcall).
76 * Syscall.cs: Move Errno-related functionality into Stdlib.
77 * UnixMarshal.cs: Use ERANGE not EPERM when figuring out appropriate
78 translator, since ERANGE is part of C99 and EPERM isn't. Use Stdlib
79 instead of Syscall for Errno-related functionality.
81 2005-02-02 Jonathan Pryor <jonpryor@vt.edu>
83 * UnixFile.cs: Cope with changes in UnixStream.
84 * UnixStream.cs: Change FileDescriptor property to Handle for consistency.
85 * StdioFileStream.cs: Change FileStream property to Handle for consistency.
87 2005-02-02 Jonathan Pryor <jonpryor@vt.edu>
89 * Syscall.cs: Remove public sys_ methods. Some were public by mistake, and
90 others so that users could manually marshal strings if desired. Manually
91 marshaling strings shouldn't be necessary, though, so remove them too.
93 2005-02-02 Jonathan Pryor <jonpryor@vt.edu>
95 * StdioFileStream.cs: Fix Length property to actually return the size of the
96 file, not the # of bytes from the current position to EOF. Oops.
98 2005-01-31 Jonathan Pryor <jonpryor@vt.edu>
100 * Stdlib.cs: Import "msvcrt", not "libc". These members are part of the
101 ANSI C standard, and thus should be present on Windows via msvcrt.dll
102 (except snprintf, until they catch up to C99). Change the calling
103 convention of all functions to Cdecl, as the .NET default is Stdcall.
104 Changing the calling convention isn't needed in Syscall, as it can only be
105 run on Unix platforms anyway, where the default is Cdecl.
106 * Syscall.cs: Add LIBC member that points to the real "libc"; we can't use
107 the imported definition from Stdlib as "msvcrt" doesn't exist on Unix.
109 2005-01-29 Jonathan Pryor <jonpryor@vt.edu>
111 * Stdlib.cs: sys_* functions shouldn't be public.
113 2005-01-13 Jonathan Pryor <jonpryor@vt.edu>
115 * make-map.cs: libMonoPosixHelper exports Mono_Posix prefixes, not Mono_Unix
116 prefixes, so change the type and namespace to generate compatible code.
117 * Syscall.cs: Change OpenFlags values so they match the Linux values.
119 2005-01-13 Jonathan Pryor <jonpryor@vt.edu>
121 * Stdlib.cs: Use Stdlib.LIBC instead of "libc".
122 * StdioFileStream.cs: Add FilePosition property (not that I expect anyone to
123 use it) and Rewind() method.
125 2005-01-05 Jonathan Pryor <jonpryor@vt.edu>
127 * StdioFileStream.cs: Added; System.IO.Stream wrapper for C FILE struct.
128 * Stdlib.cs: Correct visibility of ftell().
130 2005-01-05 Jonathan Pryor <jonpryor@vt.edu>
132 * Stdlib.cs: Re-order declarations to match the order used in the
133 C99 Standard Annex B; Complete <stdio.h> exports (except for those not
134 worth supporting); Add non-"unsafe" versions of fread(3), fwrite(3) and
135 add some rudimentary buffer-overflow checking; Add <stdlib.h> exports such
136 as getenv(3), exit(3), rand(3), EXIT_SUCCESS, RAND_MAX, etc.
138 2005-01-03 Jonathan Pryor <jonpryor@vt.edu>
140 * Syscall.cs: Update endfsent() and setfsent() declarations, as these must
141 now be implemented in MonoPosixHelper.
143 2005-01-01 Jonathan Pryor <jonpryor@vt.edu>
145 * Stdlib.cs, Syscall.cs: Minimize duplicate declarations of
146 "MonoPosixHelper" for use in DllImport statements.
148 2005-01-01 Jonathan Pryor <jonpryor@vt.edu>
150 * Stdlib.cs: Don't use C# v2 features; fixes build under CSC.EXE.
152 2004-12-30 Jonathan Pryor <jonpryor@vt.edu>
154 * Stdlib.cs: On miguel's suggestion, rename Sighandler_t to SignalHandler.
156 2004-12-30 Jonathan Pryor <jonpryor@vt.edu>
158 * Stdlib.cs: Implement all C89 <stdio.h> functions except for the scanf(3)
159 family. These are too dangerous to expose.
161 2004-12-30 Jonathan Pryor <jonpryor@vt.edu>
163 * CdeclFunctions.cs: Remove warning about unused variable.
164 * Stdlib.cs: Make signal(2) sane and (hopefully) complete.
165 * Syscall.cs: Fix cuserid Obsolete message to reference correct class name.
166 * UnixProcess.cs: Remove warning about unused variable.
167 * UnixMarshal.cs: Remove warnings about unused variables.
169 2004-12-29 Jonathan Pryor <jonpryor@vt.edu>
171 * UnixPath.cs: Add ReadSymbolicLink(), which takes an intelligent approach
172 to reading symlinks (since their contents may be any size, we grow the
173 buffer dynamically to fit them all, instead of assuming a maximum size).
174 * UnixSymbolicLinkInfo.cs: Remove MaxContentsSize.
176 2004-12-29 Jonathan Pryor <jonpryor@vt.edu>
178 * UnixPath.cs: Add check for when symlink points to a full path name.
180 2004-12-29 Jonathan Pryor <jonpryor@vt.edu>
182 * Syscall.cs: Fix Object.Equals implementations.
183 * UnixPath.cs: New & improved, with Testing! GetRealPath() is changed so
184 that it doesn't walk the entire path looking for symlinks, it just reads
185 the leaf. GetCompletRealPath() walks the entire path resolving symlinks.
186 GetCanonicalPath() added, which "cleans up" a path (removing extraneous
187 "." and ".." entries).
188 * UnixSymbolicLinkInfo.cs: Rename ContentsLength -> MaxContentsSize.
190 2004-12-28 Jonathan Pryor <jonpryor@vt.edu>
192 * UnixFileSystemInfo.cs: Add a link(2) wrapper, CreateLink(). Strictly
193 speaking it's only "safe" to do this on files, but an exception will be
194 returned if the user tries to hard link directories (because of EPERM),
195 unless the user is root, in which case it should be allowed anyway...
197 2004-12-28 Jonathan Pryor <jonpryor@vt.edu>
199 * CdeclFunctions.cs: Correct the comments for AMD64
200 * UnixDirectoryInfo.cs: override Name; add Parent & Root properties;
201 Correct Path usage (s/Path/FullPath/g).
202 * UnixDriveInfo.cs: Added. Based on .NET 2.0 System.IO.DriveInfo docs,
203 provides statvfs(2) and getfsfile(3) information about a mounted volume.
204 GetDrives() wraps getfsent(3), thus parsing /etc/fstab.
205 * UnixFile.cs: Use UnixConver.ToOpenFlags, deleting the local version.
206 * UnixFileInfo.cs: Use UnixConver.ToOpenFlags, deleting the local version;
207 override Name; add DirectoryName and Directory properties;
208 * UnixFileSystemInfo.cs: Make more .NET-like, using FullPath and
209 OriginalPath protected members, abstract Name property; Add
210 CreateSymbolicLink; Remove ReadLink (it's now
211 UnixSymbolicLinkInfo.Contents); Use lstat(2) for Create(string), so we
212 properly detect Symbolic Links.
213 * UnixPath.cs: Added; Path manipulation utility functions.
214 * UnixSymbolicLinkInfo.cs:
216 - override new abstract member Name;
217 - rename ReadLink to ContentsPath (and Contents) properties
218 (why "Contents"? Because readlink(2) says "readlink places the
219 contents of the symbolic link in the buffer...")
220 - Add CreateSymbolicLinkTo(), which creates a symlink to the specified
223 2004-12-28 Jonathan Pryor <jonpryor@vt.edu>
225 * Stdlib.cs: Add syslog(3) to XPrintfFunctions; Add additional printf(3)
226 and fprintf(3) overload which properly escape the format string
227 (by using "%s" as the format for the user-supplied message).
228 * Syscall.cs: Add #regions for enummerations, structures, classes; Wrap
229 syslog(3) and related enumerations; fix operator!= on Dirent, Group;
230 wrap {f}statvfs(2); wrap <fstab.h> entries (getfsent(3), etc.).
231 * UnixConvert.cs: Add Syslog-releated enumeration translation functions;
232 Move ToOpenFlags here from UnixFile and UnixFileInfo.
233 * UnixMarshal.cs: Missing P/Invoke methods throw
234 EntryPointNotFoundException, not MissingMethodException; add
235 EscapeFormatString, which escapes printf-style format strings so that they
236 can be safely handed off to native code (avoiding stack overflow, etc);
237 make CreateExceptionForError internal.
239 2004-12-15 Jonathan Pryor <jonpryor@vt.edu>
241 * Stdlib.cs: Add more <stdio.h> wrappers, such as fread(3) and fwrite(3).
242 These will be useful in implementing System.IO.Stream subclass for
243 reading/writing to a FILE*. Fix a typo in the realloc(3) DllImport.
244 * Syscall.cs: Fix the sys_kill and sys_crypt declarations.
245 * CdeclFunction.cs: Document calling convention problems on AMD64.
247 2004-11-18 Jonathan Pryor <jonpryor@vt.edu>
249 * CdeclFunction.cs: Added.
250 * Stdlib.cs: Re-add printf(3) and fprintf(3). They may not be portable (the
251 jury is still out on that; the AMD64 SysV ABI looks like it should be
252 portable to AMD64 to my eyes), but they will work on *some* platforms, so
253 we should permit it. The new implementation takes a page out of
254 cocoa-sharp: use System.Reflection.Emit to generate a P/Invoke method at
255 runtime to invoke printf(3) or fprintf(3). This way, we can export a
256 params signature to C# code, permitting natural usage such as:
257 Stdlib.printf ("Hello, %s world! (%i)\n", "silly", 42);
258 * Syscall.cs: Mark which headers are complete, which functions still need
259 wrapping (for headers which have anything done to them), add #region
260 blocks for each header;
261 export mkfifo(3), fexecve(), getppid(2), setlogin(); fix sleep(3) export.
262 * UnixEnvironment.cs: Export a friendly getppid(2) wrapper.
263 GetParentProcessId isn't in UnixProcess as there's no way (that I know of)
264 to get the Parent's Parent, so it can't be a class member, and exposing it
265 as a static member of UnixProcess doesn't make sense to me, as it isn't
266 general. Added GetUserShells().
267 * UnixProcess.cs: Change constructor to internal, so it can be used from
270 2004-11-16 Jonathan Pryor <jonpryor@vt.edu>
272 * Stdlib.cs: Remove printf(3) and fprintf(3). These are vararg/CDECL
273 functions, and it's not portable to call them in this manner.
274 (It's not portable because some architectures, such as AMD64, use a
275 "cookie" as part of the vararg calling sequence to help reduce buffer
276 overflow exploits. Trying to call vararg functions as if they were an
277 overloaded function will not properly set this hardware cookie, resulting
278 in a hardware exception. Talk to lupus for more information.)
280 2004-11-16 Jonathan Pryor <jonpryor@vt.edu>
282 * Syscall.cs, UnixConvert.cs: Remove mount- and umount-related
283 functionality. Mount/umount is inherently non-portable (see the C code
284 for mount/umount), and trying to provide a consistent interface is
285 impossible. If you need mount/umount support, use the command-line
286 programs mount(1) and umount(1).
288 2004-11-16 Jonathan Pryor <jonpryor@vt.edu>
290 + Lots o' Renames, as the namespace changed.
291 * PosixConvert.cs: Moved to UnixConvert.cs:
292 * PosixDirectory.cs: Moved to UnixDirectory.cs:
293 * PosixEnvironment.cs: Moved to UnixEnvironment.cs:
294 * PosixDirectoryInfo.cs: Moved to UnixDirectoryInfo.cs:
295 * PosixFile.cs: Moved to UnixFile.cs:
296 * PosixFileInfo.cs: Moved to UnixFileInfo.cs:
297 * PosixFileSystemInfo.cs: Moved to UnixFileSystemInfo.cs:
298 * PosixGroup.cs: Moved to UnixGroup.cs:
299 * PosixGroupInfo.cs: Moved to UnixGroupInfo.cs:
300 * PosixIOException.cs: Moved to UnixIOException.cs:
301 * PosixMarshal.cs: Moved to UnixMarshal.cs:
302 * PosixProcess.cs: Moved to UnixProcess.cs:
303 * PosixStream.cs: Moved to UnixStream.cs:
304 * PosixSymbolicLinkInfo.cs: Moved to UnixSymbolicLinkInfo.cs:
305 * PosixUser.cs: Moved to UnixUser.cs:
306 * PosixUserInfo.cs: Moved to UnixUserInfo.cs:
307 * Catalog.cs, IncludeAttribute.cs, MapAttribute.cs, PeerCred.cs, Stdlib.cs,
308 Syscall.cs, UnixConvert.cs, UnixDirectory.cs, UnixDirectoryInfo.cs,
309 UnixEndPoint.cs, UnixEnvironment.cs, UnixFile.cs, UnixFileInfo.cs,
310 UnixFileSystemInfo.cs, UnixGroup.cs, UnixGroupInfo.cs, UnixIOException.cs,
311 UnixMarshal.cs, UnixProcess.cs, UnixStream.cs, UnixSymbolicLinkInfo.cs,
312 UnixUser.cs, UnixUserInfo.cs: Deal with renamed classes/members.
314 2004-11-15 Jonathan Pryor <jonpryor@vt.edu>
316 * PosixUserInfo.cs: Make the PosixUserInfo(Passwd) constructor public;
317 override Object.GetHashCode and Object.Equals.
318 * PosixGroupInfo.cs: Make the PosixGroupInfo(Group) constructor public;
319 override Object.GetHashCode and Object.Equals.
320 * PosixIOException.cs: Use PosixMarshal.GetErrorDescription instead of
321 calling Syscall.strerror_r directly
322 * PosixMarshal.cs: Add GetErrorDescription. Strerror_r() isn't portable, so
323 GetErrorDescription() first tries strerror_r(), and if it fails falls back
326 - Seal the Dirent class. It has no virtual members, so there's no point
327 in it being non-sealed. Override Object.GetHashCode and Object.Equals.
328 - Seal the Group class. It has no virtual members, so there's no point
329 in it being non-sealed. Override Object.GetHashCode and Object.Equals.
330 Provide operator== and operator!=.
331 - Seal the Passwd class. It has no virtual members, so there's no point
332 in it being non-sealed. Override Object.GetHashCode and Object.Equals.
333 Provide operator== and operator!=.
334 - Remove strerror_r() convenience overload. This is now
335 PosixMarshal.GetErrorDescription().
337 2004-11-12 Jonathan Pryor <jonpryor@vt.edu>
339 * Syscall.cs: Export time-related functions (gettimeofday, settimeofday,
340 utime, utimes), mknod.
342 2004-11-07 Atsushi Enomoto <atsushi@ximian.com>
344 * PosixEnvironment.cs : csc build fix. see bug #69195.
345 * PosixStream.cs : csc build fix. see bug #69196.
347 2004-11-05 Jonathan Pryor <jonpryor@vt.edu>
349 * PosixConvert.cs: New file; conversion functions for Mono.Posix types.
350 * PosixDirectory.cs: New file; Friendly wrapper over directory information.
351 * PosixDirectoryInfo.cs: New file; Friendly wrapper over directory information.
352 * PosixEnvironment.cs: New file; Friendly wrapper over environment information.
353 * PosixFile.cs: New file; Friendly wrapper over file information.
354 * PosixFileInfo.cs: New file; Friendly wrapper over file information.
355 * PosixFileSystemInfo.cs: New file; Friendly wrapper over `stat'.
356 * PosixGroup.cs: New file; User Group-related functionality
357 * PosixGroupInfo.cs: New file; User Group-related functionality
358 * PosixIOException.cs: New file; Exception for POSIX-generated exceptions.
359 * PosixMarshal.cs: New file; utility functions for marshaling, etc.
360 * PosixProcess.cs: New file; Friendly wrapper over process information.
361 * PosixStream.cs: New file; Friendly wrapper over file descriptors.
362 * PosixSymbolicLinkInfo.cs: New file; Friendly wrapper over symbolic links.
363 * PosixUser.cs: New file; Friendly wrapper over user information.
364 * PosixUserInfo.cs: New file; Friendly wrapper over user information.
365 * Stdlib.cs: New file; C standard library exports.
366 * Syscall.cs: Effective re-write.
367 - Organize exports by header file
368 - add additional enumerations (Error for the E* error values, etc.)
369 - always explicitly specify enumeration underlying type
370 - Use a new wrapping infrastructure so that ABI-stable types are exported
371 - For example, size_t is exported as ulong, not IntPtr.
372 - Wrap more functions, and wrap them better (such as getpwnam).
373 - This release is NOT backward compatible. Many names are the same, and
374 hopefully they're still compatible, but no effort was made to maintain
375 compatibility. For example, FileMode was removed and replaced with
376 FilePermissions, to avoid a name conflict with System.IO.FileMode.
377 - Change umount() to use MonoPosixHelper: portability fix for Mac OS X.
378 * make-map.cs: Another effective re-write, to clean up the code, produce
379 better output, and produce more output. For example, most of
380 PosixConvert can be auto-generated, so it is (modulo version delays and
381 bootstrap issues). `map.c' is now conditional on all macros, and has
382 error checking for invalid/unsupported values.
384 2004-09-18 Jackson Harper <jackson@ximian.com>
386 * Syscall.cs: Add support for poll ().
388 2004-09-18 Jackson Harper <jackson@ximian.com>
390 * make-map.cs: Use field value not name for #defines.
392 2004-09-14 Loren Bandiera <lorenb@mmgsecurity.com>
394 * Syscall.cs: Added method for getpwnam which uses Passwd
396 * macros.c: Helper function for getpwnam
397 (In committing, Josh Tauberer also added getpwuid.)
399 2004-07-09 Dick Porter <dick@ximian.com>
401 * PeerCred.cs: Get the unix socket peer credentials.
403 2004-05-26 Miguel de Icaza <miguel@ximian.com>
405 * Syscall.cs: Do not let the runtime handle strings, as we do not
406 own those strings, we must transform the char * into a string
409 2004-05-03 Miguel de Icaza <miguel@ximian.com>
411 * Syscall.cs: Add symlink
413 2004-04-19 Miguel de Icaza <miguel@ximian.com>
415 * Syscall.cs: Use hex values for FileMode, since C# does not have
416 an octal integer mode.
418 2004-03-30 Joshua Tauberer <tauberer@for.net>
420 * Added readlink, strerror, opendir, readdir, closedir
421 * Added Mono.Posix.Stat.UnixToDateTime(long unixtime) --> DateTime
423 2004-03-11 Joshua Tauberer <tauberer@for.net>
425 * Syscall.cs: Removed argument to getgid that shouldn't be there.
426 Added getusername, getgroupname which wrap getpwuid, getgrgid
427 without dealing with pointers to structures.
428 Removed duplicate FileMode enum nested in Syscall class.
429 Added stat and lstat, which use StatMode enumeration
430 (like FileMode but nicer and complete) and Stat struct.
431 * macros.c: Helper functions for getpwuid, getgrgid, stat, lstat.
433 2004-01-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
435 * Syscall.cs: moved the assembly attribute to a proper place
437 * make-map.cs: use reflection to invoke the properties, as it
438 fails under MS runtime.
441 2004-01-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
443 * Syscall.cs: moved assembly attribute and added unsafe block to fix
444 the build on windows.
446 2003-11-11 Wojciech Polak <polak@gnu.org
448 * Syscall.cs: Applied patch from Wojciech Polak <polak@gnu.org> to
451 2003-05-16 Dick Porter <dick@ximian.com>
453 * UnixEndPoint.cs: New property to get and set the filename, like
454 the IPEndPoint has for the IP address. Also implement ToString().
456 Tue Apr 29 16:53:56 CEST 2003 Paolo Molaro <lupus@ximian.com>
458 * Syscall.cs: remove the unsafe mess.
460 2003-02-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
463 * UnixEndPoint.cs: first file.
