Raw Blame History

2010-04-15 Jonathan Pryor <jpryor@novell.com>
* UnixSignal.cs: Change the native WaitAny() method to accept a
Mono_Posix_RuntimeIsShuttingDown delegate, so that we can prevent an
infinite loop while shutting the process down. Fixes #592981.
2009-03-23 Jonathan Pryor <jpryor@novell.com>
* UnixDriveInfo.cs: UnixDriveInfo.AvailableFreeSpace needs to return
stat.f_bavail * stat.f_frsize, NOT f_bavail*f_bsize, as on some
platforms (Solaris) bsize is the preferred block I/O size, while
f_frsize is the *actual* filesystem block size. Thus, to get proper
disk under Solaris, we need to s/f_bsize/f_frsize/g.
2009-02-20 Jonathan Pryor <jpryor@novell.com>
* UnixSignal.cs: Add a pipecnt member to UnixSignal.SignalIinfo.
Patch thanks to tim.jenks@realtimeworlds.com.
2009-02-09 Jonathan Pryor <jpryor@novell.com>
* UnixGroupInfo.cs (GetMembers): Skip group members which aren't valid
users on the system (thus removing a possible exception). Patch
thanks to Daniel Peñalba.
2009-01-08 Rodrigo Kumpera <rkumpera@novell.com>
* UnixSignal.cs: Check if realtime signal install failed with
EADDRINUSE due to the signal been used by outside of Mono.Posix.
2008-12-19 Jonathan Pryor <jpryor@novell.com>
* UnixSignal.cs: Allow RealTimeSignums to be used in addition to
Signum, so that real time signals can be used. Patch thanks to
tim.jenks@realtimeworlds.com.
2008-11-04 Andrés G. Aragoneses <aaragoneses@novell.com>
* UnixStream.cs: Do not check offset against int.MaxValue
(System.IO doesn't have it). Reviewed by Jonathan Pryor.
Bug reported by Siro Blanco <siro.blanco@gmail.com>.
2008-11-03 Miguel de Icaza <miguel@novell.com>
* UnixClient.cs (Client): Make this property public when using the
Mono 2.0 profile, based on a discussion with Vlad Hociota and Joe
Shaw.
2008-02-11 Jonathan Pryor <jpryor@novell.com>
* UnixSignal.cs: Improve argument checking to match docs.
2008-02-08 Jonathan Pryor <jpryor@novell.com>
* UnixSignal.cs: UnixSignal.WaitAny() should have the same return type as
WaitHandle.WaitAny(). Oops.
2008-02-08 Jonathan Pryor <jpryor@novell.com>
* UnixSignal.cs: Modification of Info->count should be thread safe.
2008-01-28 Jonathan Pryor <jpryor@novell.com>
* UnixSignal.cs: Added; Polling and blocking based Unix signal mechanism.
http://lists.ximian.com/pipermail/mono-devel-list/2008-January/026501.html
2008-01-22 Sebastien Pouliot <sebastien@ximian.com>
* UnixPipes.cs: Fix Equals to avoid NRE (and return false if object
is null). Found using Gendarme.
2007-12-17 Jonathan Pryor <jpryor@novell.com>
* UnixEnvironment.cs: Update MachineName property accesor to use uname(2)
instead of gethostname(2), as gethostname(2) truncates the machine name to
16 characters, while uname(2) doesn't.
2007-12-17 Jonathan Pryor <jonpryor@vt.edu>
* UnixDirectoryInfo.cs: Fix Parent property so that it properly handles
returning the parent of "/". UnixPath.GetDirectoryName() returns "" on
"error", not null; act accordingly.
* UnixDriveInfo.cs: Fix IsReady property so that it returns `false' if no
media is mounted. The presence of media is determined by comparing the
Statvfs.f_fsid value of the current and parent directories; if they
differ, it is assumed that media is present, and thus the directory is
ready. If they're identical, then media isn't present, and the directory
isn't ready.
* UnixPath.cs: UnixPath.GetDirectoryName("/mnt") should return "/", not "".
2007-09-13 Jonathan Pryor <jonpryor@vt.edu>
* UnixStream.cs: Don't read/write if the buffer has no data. Fixes #82836.
2006-10-24 Jonathan Pryor <jonpryor@vt.edu>
* MapAttribute.cs: Moved to ../Mono.Unix.Native/MapAttribute.cs.
2006-08-21 Jonathan Pryor <jonpryor@vt.edu>
* UnixStream.cs: .Close() shouldn't close(2) the fd unless owner==true;
.Flush() should be a no-op (as System.IO.Stream.Flush doesn't gaurantee
that .Flush() actually flush to disk, and .Flush() slows things down a
lot); see: http://joeshaw.org/2006/08/21/415.
2006-08-16 Alp Toker <alp@atoker.com>
* UnixEndPoint.cs:
* AbstractUnixEndPoint.cs: Second half of the fix for #79084.
Add support for the abstract namespace, and update existing file-based
UnixEndPoint (de)serialization to reflect changes in the runtime.
2006-07-02 Jonathan Pryor <jonpryor@vt.edu>
* UnixSymbolicLinkInfo.cs: Oops. CreateSymbolicLinkTo() should create
FullPath, not OriginalName. This was fixed in one overload in January,
but I missed an overload. :-/
2006-07-02 Jonathan Pryor <jonpryor@vt.edu>
* UnixPath.cs: Follow .NET's System.IO.Path.Combine() behavior, and "reset"
the generated path if any argument beings with a path root --
UnixPath.Combine("/a", "/b") should return "/b", not "/a/b". Fixes #78580.
2006-04-21 Jonathan Pryor <jonpryor@vt.edu>
* UnixFileSystemInfo.cs: rename Create() to GetFileSystemEntry(), and make
it public (so that other's don't need to worry about the
Syscall.lstat()-and-switch to create a UnixFileSystemInfo instance).
* UnixDirectoryInfo.cs, UnixSymbolicLinkInfo.cs:
s/Create/GetFileSystemEntry/g (to cope with above change).
2006-03-09 Gonzalo Paniagua Javier <gonzalo@ximian.com>
* UnixEndPoint.cs: added GetHashCode/Equals.
2006-03-06 Jonathan Pryor <jonpryor@vt.edu>
* UnixDriveInfo.cs: Remove requirement that mountPoints be avaible via
getfsfile(3). This isn't always the case -- in particular drives mounted
via HAL and other mechanisms won't be listed in /etc/fstab, and thus won't
be returned via getfsfile(3). If getfsfile(3) fails, then we "guess" on
the drive format and volume label.
* UnixStream.cs: RefreshStat() should assert that the instance hasn't been
disposed.
* UnixEnvironment.cs (GetConfigurationValue, GetConfigurationString): Fix
error checking.
2006-02-23 Jonathan Pryor <jonpryor@vt.edu>
* UnixFileSystemInfo.cs: Create() should return a UnixFileInfo if the file
doesn't exist. This allows callers to use UnixFileInfo.Exists to see if
the file exists, and behaves more rationally e.g. if the directory
contents changes while calling UnixDirectoryInfo.GetFileSystemEntries(),
we'll get a UnixFileInfo entry that doesn't exist instead of an exception
terminating the entire array creation.
* UnixSymbolicLinkInfo.cs: [Obsolete] the Contents property -- this property
*always* creates a new object if HasContents=true, and since a
UnixFileSystemInfo instance is (104+2*(sizeof(void*))+1) bytes (~113 bytes
on 32-bit platforms), we don't want to create these frequently. Add a
GetContents() method as the replacement, to make it (slightly) more
explicit that information won't be cached (and thus should be cached by
the caller, if appropriate). GetContents() throws an exception if
HasContents=false instead of returning null; this change brings the
implementation in line with the documentation.
2006-02-18 Alp Toker <alp@atoker.com>
* UnixEndPoint.cs: Avoid truncation of last two bytes of SocketAddress
string
2006-01-26 Jonathan Pryor <jonpryor@vt.edu>
* UnixMarshal.cs: Check for null arguments in PtrToString() and
PtrToStringArray().
2006-01-24 Jonathan Pryor <jonpryor@vt.edu>
* UnixMarshal.cs (StringToHeap): Return IntPtr.Zero if `s' is null.
2006-01-24 Jonathan Pryor <jonpryor@vt.edu>
* UnixMarshal.cs (StringToHeap): Check for null arguments.
2006-01-20 Jonathan Pryor <jonpryor@vt.edu>
* UnixDriveInfo.cs: Properties should generate an InvalidOperationException,
not an IOException. Users can use IsReady to avoid exception generation.
* UnixIOException.cs: Create a custom message that embeds the error name
within the text, e.g. "Permission denied [EACCES]."
* UnixSymbolicLinkInfo.cs: This really should create the file FullPath, not
OriginalPath. Created files shouldn't ever be relative to the current
working directory, as this can change at any time.
2006-01-15 Jonathan Pryor <jonpryor@vt.edu>
* UnixUserInfo.cs: The UnixUserInfo(Native.Passwd) constructor and
ToPasswd() should clone the underlying Native.Passwd, so
that it doesn't get changed from underneath it.
* UnixGroupInfo.cs: The UnixGroupInfo(Native.Group) constructor should also
clone the provided Native.Group instance.
2006-01-14 Jonathan Pryor <jonpryor@vt.edu>
* UnixGroupInfo.cs: ToGroup() should clone the underlying Native.Group, so
that it doesn't get changed from underneath it.
2006-01-13 Jonathan Pryor <jonpryor@vt.edu>
* Catalog.cs, UnixMarshal.cs: Throw `UnixIOException(Native.Errno.ENOMEM)`
instead of System.OutOfMemoryException. OOME should be reserved for use
by the CLR (according to FxDG).
2006-01-12 Jonathan Pryor <jonpryor@vt.edu>
* UnixPath.cs: Add ReadLink() and TryReadLink() methods.
2006-01-12 Miguel de Icaza <miguel@novell.com>
* PeerCred.cs: Do not define PeerCredData as this is a structure
known to the runtime. Instead use the Mono.Posix.PeerCredData
internal class.
2006-01-10 Jonathan Pryor <jonpryor@vt.edu>
* Catalog.cs: Don't use
System.Runtime.InteropServices.Marshal.StringToHGlobalAuto(), use
UnixMarshal.StringToHeap(). We require that the converted string be in
UTF-8 format, but .NET's Marshal.StringToHGlobalAuto converts to the local
code page, *not* UTF-8 (Mono's does UTF-8). UnixMarshal.StringToHeap
*always* does UTF-8, so use that instead.
2006-01-09 Jonathan Pryor <jonpryor@vt.edu>
* FileTypes.cs: Remove [Flags] attribute -- these aren't bitfield values.
* UnixFileSystemInfo.cs: Fix Is<<Type>> properties -- before it would
erroneously say that a symlink was a character device. (This is because
device values are *not* [Flags] values, but code was assuming they were.)
* UnixGroupInfo.cs: Clone the string[] returned from GetMemberNames(). We
don't want callers to change the underlying list.
2006-01-07 Jonathan Pryor <jonpryor@vt.edu>
* UnixMarshal.cs: *Actually* put things in alphabetical order (like the
comment says). I can speak english, really I can.
2006-01-06 Jonathan Pryor <jonpryor@vt.edu>
* Catalog.cs: s/libintl/intl/g, since intl.dll is used by GTK+ on Windows,
not libintl.dll (according to
http://www.gimp.org/~tml/gimp/win32/downloads.html).
2006-01-03 Jonathan Pryor <jonpryor@vt.edu>
* UnixMarshal.cs (CreateExceptionForError): Don't map ENOMEM to
System.OutOfMemoryException. OOME should be reserved for use by the CLR.
Return a UnixIOException instead (default behavior).
2006-01-02 Jonathan Pryor <jonpryor@vt.edu>
* StdioFileStream.cs: Shut up FxCop - add a GC.KeepAlive to
AssertNotDisposed().
* UnixClient.cs, UnixListener.cs: Use System.MarshalByRefObject as the base
class. These types implement IDisposable and have a finalizer, so if an
instance of these types were sent to another AppDomain they'd previously
marshal by copy, which could lead to a double release of an unmanaged
resource -- potential badness. Using MarshalByRefObject fixes this.
2006-01-02 Jonathan Pryor <jonpryor@vt.edu>
* UnixMarshal.cs: s/EACCESS/EACCES/g. I can't read.
2006-01-02 Jonathan Pryor <jonpryor@vt.edu>
* StdioFileStream.cs, UnixDirectoryInfo.cs, UnixEnvironment.cs,
UnixFileInfo.cs, UnixFileSystemInfo.cs, UnixGroupInfo.cs,
UnixIOException.cs, UnixMarshal.cs, UnixProcess.cs, UnixStream.cs,
UnixSymbolicLinkInfo.cs, UnixUserInfo.cs: Remove Obsolete API.
* CdeclFunction.cs, IncludeAttribute.cs, Stdlib.cs, Syscall.cs,
UnixConvert.cs, UnixDirectory.cs, UnixFile.cs, UnixGroup.cs,
UnixUser.cs: Delete.
* UnixPath.cs: Remove InvalidPathChars; use GetInvalidPathChars() instead.
* FileTypes.cs: Remove Obsolete API
2006-01-02 Jonathan Pryor <jonpryor@vt.edu>
* FileAccessPermissions.cs: Remove UserMask, GroupMask, OtherMask values.
* FileSpecialAttributes.cs: Remove AllAttributes member; it shouldn't be
public. Use UnixFileSystemInfo.AllSpecialAttributes instead.
* StdioFileStream.cs: Open files in binary mode, not text;
Fix exception message for StdioFileStream(path, mode) mode param check.
* UnixDirectoryInfo.cs: Add Create(FileAccessPermissions) overload; change
GetFileSystemEntries() to include the directory name that the files came
from (otherwise they're in the current working direcetory, which they
probably aren't).
* UnixFileInfo.cs: Add Create(FileAccessPermissions) overload; Add better
argument checking to several Open() overloads.
* UnixFileSystemInfo.cs: Add AllSpecialAttributes, AllFileTypes members;
FullPath member should invalidate instance if path changes; Change return
type of GetFileStatus for maintenance/better documentation; ToStat()
should ensure that the instance is valid first.
* UnixMarshal.cs: Add additional Errno values to CreateExceptionForError();
reformat CreateExceptionForError for maintenance.
* UnixPath.cs: Obsolete InvalidPathChars -- FxCop never liked it, and now I
know why it didn't like it (thank you Framework Design Guidelines!).
* UnixStream.cs: Use UnixFileSystemInfo.AllSpecialAttributes, not
FileSpecialAttributes.AllAttributes (which was removed).
* UnixSymbolicLinkInfo.cs: Change return type of GetFileStatus().
2005-12-28 Jonathan Pryor <jonpryor@vt.edu>
* FileHandleOperations.cs: Check for null references.
2005-12-28 Jonathan Pryor <jonpryor@vt.edu>
* UnixMarshal.cs: Errno.EBADF should also trigger a ArgumentException.
2005-12-27 Jonathan Pryor <jonpryor@vt.edu>
* FileHandleOperations.cs, FileTypes.cs, Stdlib.cs, Syscall.cs,
UnixConvert.cs, UnixDirectory.cs, UnixDirectoryInfo.cs, UnixDriveInfo.cs,
UnixEnvironment.cs, UnixFile.cs, UnixFileInfo.cs, UnixFileSystemInfo.cs,
UnixGroup.cs, UnixGroupInfo.cs, UnixIOException.cs, UnixMarshal.cs,
UnixPath.cs, UnixPipes.cs, UnixProcess.cs, UnixStream.cs,
UnixSymbolicLinkInfo.cs, UnixUser.cs, UnixUserInfo.cs: Mark to-be-removed
API with [Obsolete(IsError=true)] (permits compiler assistance for finding
obsolete code); Migrate to the Mono.Unix.Native API.
* StdioFileStream.cs: Add non-Obsolete overloads for SaveFilePosition &
RestoreFilePosition (oops). Migrate to Mono.Unix.Native API.
2005-12-07 Jonathan Pryor <jonpryor@vt.edu>
* UnixMarshal.cs: Add PtrToStringUnix() -- specialized PtrToString method
which is significantly faster than PtrToString(p, UnixEncoding.Instance).
Use System.String..ctor(sbyte*, int, int, Encoding) to avoid the byte[]
intermediate copy -- much faster. Fix PtrToString() so that it will
accept an IntPtr containing 0 characters, and don't duplicate strings
unless necessary.
2005-11-18 Jonathan Pryor <jonpryor@vt.edu>
* Catalog.cs, UnixDirectory.cs, UnixDirectoryInfo.cs, UnixDriveInfo.cs,
UnixEnvironment.cs, UnixFile.cs, UnixFileInfo.cs, UnixFileSystemInfo.cs,
UnixGroup.cs, UnixGroupInfo.cs, UnixProcess.cs, UnixSymbolicLinkInfo.cs,
UnixUser.cs, UnixUserInfo.cs: Change types of [Obsolete] members for
consistency and CLS compliance; Mono.Unix.Native type migration.
* FileTypes.cs: s/Special/Device/g (CharacterSpecial ==> CharacterDevice).
The *Special was a BSD convention, while UnixFileSystemInfo uses *Device
in property names, and these should be consistent. Changing the enum is
simpler than changing the UnixFileSystemInfo properties.
* UnixIOException.cs: s/error/errno/g (FxCop suggestion); change type of
ErrorCode property.
* UnixMarshal.cs: s/error/errno/g (FxCop suggestion); Mono.Unix.Native
type migration.
2005-11-08 Jonathan Pryor <jonpryor@vt.edu>
* Catalog.cs: Exception safety improvements (don't let memory leak!); check
for errors with bindtextdomain(3) et. al.
2005-11-08 Jonathan Pryor <jonpryor@vt.edu>
* UnixPipes.cs: Provide Equals, GetHashCode, and operator==/operator!= to
conform with FxCop guidelines for structures.
2005-11-03 Jonathan Pryor <jonpryor@vt.edu>
* FileTypes.cs, UnixFileSystemInfo.cs: s/FIFO/Fifo/ to follow .NET
naming conventions (as reported by FxCop).
2005-11-01 Jonathan Pryor <jonpryor@vt.edu>
* UnixDirectoryInfo.cs, UnixDriveInfo.cs, UnixEnvironment.cs,
UnixFileSystemInfo.cs, UnixGroupInfo.cs, UnixProcess.cs, UnixUserInfoc.cs:
Obsolete statements now specify in what way the return type will change.
* IncludeAttribute.cs: Obsoleted. It's an error to use it now.
2005-11-01 Jonathan Pryor <jonpryor@vt.edu>
* FileAccessPattern.cs: Change enumeration names to match Robert Love's more
sensible names from his FileAdvise class used in Beagle
(UseSoon --> PreLoad, WillNotUse --> FlushCache).
* FileHandleOperations.cs: Added; contains AdviseFileAccessPattern()
(moved from UnixFile.cs).
* UnixDirectory.cs: Obsolete the class; use UnixDirectoryInfo instead.
* UnixDirectoryInfo.cs: Add GetCurrentDirectory(), SetCurrentDirectory().
* UnixFile.cs: Obsolete the class; use UnixFileInfo, FileHandleOperations,
or UnixPipes instead.
* UnixFileSystemInfo.cs: Add ToStat() method.
* UnixGroup.cs: Obsolete the class; use UnixGroupInfo instead.
* UnixGroupInfo.cs: Obsolete & Replace constructor, add GetMemberNames(),
GetLocalGroups().
* UnixPipes.cs: Added (type moved from UnixFile.cs).
* UnixStream.cs: AdviseFileAccessPattern() uses FileHandleOperations now.
* UnixSymbolicLinkInfo.cs: Implement TryReadLink() to avoid constant buffer
re-sizing. Stevens states that the file size of the symlink is the number
of bytes needed to hold the symlink, so this should be faster.
* UnixUser.cs: Obsolete the class; use UnixUserInfo instead.
* UnixUserInfo.cs: Obsolete & Replace constructor; add useful static members
from UnixUser such as GetLoginName(), GetLocalUsers(), etc.
2005-10-27 Jonathan Pryor <jonpryor@vt.edu>
* UnixEnvironment.cs: Add RealUser, RealGroup, EffectiveUser, EffectiveGroup
properties; [Obsolete] necessary methods and provide replacements.
* UnixStream.cs: Add OwnerUser(Id), OwnerGroup(Id) properties;
improve Stat handling.
2005-10-26 Jonathan Pryor <jonpryor@vt.edu>
* UnixEncoding.cs: Change EscapeByte to 0x0000, as suggested by Michal
Moskal.
* UnixPath.cs: Remove '\0' from InvalidPathChars, since U+0000 is now used
as the path escape character for marshaling purposes.
2005-10-26 Jonathan Pryor <jonpryor@vt.edu>
* UnixMarshal.cs: Obsolete heap-related methods to have a Heap suffix
(AllocHeap, FreeHeap, etc.), and change StringToAlloc() to be
StringToHeap(). This creates a stronger name association between related
methods.
2005-10-26 Jonathan Pryor <jonpryor@vt.edu>
* UnixIOException.cs: Add (string) and (string, Exception) constructors to
silence FxCop; re-work logic so we lookup the error string at construction
time and use this as the message for the base class.
2005-10-25 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs, Syscall.cs: Filenames need to be marshaled through the
FileNameMarshaler, which will encode/decode filenames with UnixEncoding.
* UnixEncoding.cs: Added (copied from
../../corlib/System.Text/UTF8Encoding.cs); a hack to permit handling of
arbitrarily encoded filenames. It attempts to decode a byte[] array as
UTF-8, and if the decode fails it prefixes each byte with
UnixEncoding.EscapeByte (\uFFFF).
* UnixMarshal.cs: Use UnixEncoding as the default encoding, and special-case
UnixEncoding to use Stdlib.strlen() for native string lengths.
2005-10-21 Jonathan Pryor <jonpryor@vt.edu>
* FileAccessPattern.cs: Added
* UnixFile.cs, UnixStream.cs: Deprecate all the Advise* methods (lots!)
and replace with 6 methods which take a FileAccessPattern enum.
2005-10-19 Jonathan Pryor <jonpryor@vt.edu>
* FileAccessPermissions.cs, FileSpecialAttributes.cs, FileTypes.cs: Added.
* UnixFileSystemInfo.cs, UnixStream.cs: Replace the old Permission property
with 4 new properties: Protection (for the Native.FilePermissions value),
FileAccessPermissions (for rwxrwxrwx info), FileSpecialAttributes (for
set-user-id, set-group-id, sticky), and FileTypes (directory, socket...).
The new enumeration types have nicer CLS-compliant names.
2005-10-17 Jonathan Pryor <jonpryor@vt.edu>
* UnixMarshal.cs: Fix GetIntXxBufferLength to require fewer
Marshal.ReadIntXx() calls; Fix PtrToString so that
``"foo" == PtrToString (StringToAlloc("foo",enc),enc)'' is true for
"random" encodings.
2005-10-17 Jonathan Pryor <jonpryor@vt.edu>
* UnixFileSystemInfo.cs: Add OwnerUserId and OwnerGroupId properties.
2005-10-17 Jonathan Pryor <jonpryor@vt.edu>
* UnixDriveInfo.cs, UnixEnvironment.cs, UnixFile.cs, UnixFileSystemInfo.cs,
UnixGroup.cs, UnixStream.cs, UnixUser.cs: Don't use SetLastError(), since
it's use is (1) incorrect, and (2) will be going away with the move to
Mono.Unix.Native.Syscall. Instead use the Native.Syscall.* APIs which
set errno sanely.
2005-10-17 Jonathan Pryor <jonpryor@vt.edu>
* UnixGroup.cs, UnixGroupInfo.cs, UnixFile.cs, UnixFileSystemInfo.cs,
UnixStream.cs, UnixSymbolicLinkInfo.cs, UnixUser.cs, UnixUserInfo.cs:
Start migrating uid/gid to long (from uint) for CLS compliance.
(Full migration must wait 'til after the next release as this would
require changes to existing members.)
* UnixEnvironment.cs: Above, and add RealUserId/RealGroupId and
EffectiveUserId/EffectiveGroupId.
2005-10-14 Jonathan Pryor <jonpryor@vt.edu>
* Catalog.cs: Create a constructor and mark it [Obsolete]. It will be made
private after the next release.
* UnixFile.cs, UnixStream.cs: Deal with Mono.Unix.Native type name changes.
* UnixFileSystemInfo.cs: [Obsolete] more members; Deal with Mono.Unix.Native
type name changes.
* Syscall.cs: Create maps for PathConf, SysConf, ConfStr again; fpathconf(),
pathconf(), and sysconf() should call Native.Syscall since the
MonoPosixHelper.so helpers have changed.
2005-10-13 Jonathan Pryor <jonpryor@vt.edu>
* UnixMarshal.cs: More/better StringToAlloc/PtrToString which take a
System.Text.Encoding instance for proper string marshaling.
- PtrToString(string,Encoding) is particularly tricky due to variable
length encodings.
- Fix StringToAlloc so that it works properly with UTF-16 encodings
(we need a terminating null 16-bit word, not a null byte).
- StringToAlloc overload for doing substrings.
2005-10-12 Jonathan Pryor <jonpryor@vt.edu>
* UnixStream.cs: Check for EROFS and EINVAL in Flush(). Snorp was getting
an exception when he created a UnixStream around a socket, because
sockets can't be flushed. It should be acceptable to create a UnixStream
around a socket, so don't throw an exception in this scenario.
2005-10-06 Jonathan Pryor <jonpryor@vt.edu>
* UnixDirectory.cs, UnixDirectoryInfo.cs UnixFile.cs, UnixFileSystemInfo.cs,
UnixGroupInfo.cs, UnixIOException.cs, UnixStream.cs, UnixUserInfo.cs:
API Review: Obsolete appropriate members and add appropriate overloads for
pending move to Mono.Unix.Native types.
* UnixMarshal.cs: API Review; add StringToAlloc().
2005-09-26 Jonathan Pryor <jonpryor@vt.edu>
* UnixFileSystemInfo.cs: Exists shouldn't use access(2), as (1) Exists isn't
virtual, and (2) access(2) errors if you try to access(2) a symlink which
points nowhere. Use (l)stat(2) instead, via GetFileStatus(), as this lets
UnixSymbolicLinkInfo behave properly.
* UnixSymbolicLinkInfo.cs: The Contents property should return null if the
symlink target doesn't exist.
2005-09-20 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs: Add [Map] to AccessMode and MmapProt, as the Mono.Unix.Native
replacements go by different names (AccessModes, MmapProts), but we need
to continue generating the mapping code for these types (backward compat).
2005-09-20 Jonathan Pryor <jonpryor@vt.edu>
* CdeclFunction.cs: [Obsolete]d by Mono.Unix.Native.CdeclFunction.
* make-map.cs: Remove.
* Stdlib.cs: [Obsolete] the types; use the Mono.Unix.Native.* types instead.
* StdioFileStream.cs: Add GC.KeepAlive statements to prevent premature GC's
(FxCop suggestion).
* Syscall.cs: Remove [Map] attribute from all types; [CLSCompliant(false)]
work; [Obsolete] all types and suggest using the Mono.Unix.Native.*
replacements; remove [IncludeAttribute] -- superseded by
Mono.Unix.Native/Syscall.cs's [HeaderAttribte] for CLS compliance.
* UnixConvert.cs: [Obsolete]d by Mono.Unix.Native.NativeConvert.
* UnixDirectory.cs, UnixDriveInfo.cs, UnixEnvironment.cs,
UnixGroup.cs, UnixGroupInfo.cs,
UnixSymbolicLinkInfo.cs, UnixUser.cs, UnixUserInfo.cs:
Add [CLSCompliant(false)] as necessary.
* UnixFile.cs, UnixDirectory.cs, UnixFileInfo.cs, UnixFileSystemInfo.cs:
[CLSCompliant(false)], addition of method overloads for [Obsolete]d types,
warn about changing return types.
* UnixProcess.cs, UnixStream.cs: Add [CLSCompliant(false)] as necessary,
and warn about changing property types.
2005-09-02 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: Cache delegates passed to Stdlib.signal() so that they survive
garbage collections. Delegates can be removed by calling Stdlib.signal()
again with one of the Stdlib.SIG_* values (or the original return value of
Stdlib.signal()).
* UnixUser.cs, UnixGroup.cs, UnixEnvironment.cs: Clarify "Id" (int) vs.
"Name" (string) differences by always using a Id or Name suffix.
2005-07-01 Daniel Drake <dsd@gentoo.org>
* Syscall.cs: The entire extended attribute API now goes through MPH, to
be shared between both Linux's and FreeBSD's similar EA implementations.
2005-06-29 Miguel de Icaza <miguel@ximian.com>
* StdioFileStream.cs: Only flush if we do not own the handle, as
fclose does a flush internally.
2005-06-29 Jonathan Pryor <jonpryor@vt.edu>
* UnixEnvironment: Add User, Login properties.
* Syscall.cs: Add locking around cuserid, crypt, encrypt, getlogin.
2005-06-29 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs: SyslogFacility shouldn't be [Flags] either. Sigh.
Thanks to Vorobiev Maksim for pointing this out.
* make-map.cs: Don't generate conversion code for [Obsolete] enum members.
This assumes that (1) the enum member's value is invalid, or (2) a
corrected member with the same value exists. This fix allows us to
obsolete invalid members (instead of removing them) without screwing up
the generated code -- consider LOG_USRE, the mis-spelling of LOG_USER.
Since SyslogFacility was (incorrectly) a [Flags] enum, since both LOG_USER
and LOG_USRE had the same value, we'd get a EINVAL error trying to convert
a valid value, since LOG_USRE would exist, would be checked for, and the
check would succeed (since it had the same value as LOG_USER).
This change allows us to be slightly more permissive with versioning.
2005-06-28 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs: correct value of LOG_CRON (it shouldn't be identical to
LOG_UUCP). SyslogLevel shouldn't have [Flags]. Move LOG_USER to be
before LOG_USRE so that the generated map code doesn't return EINVAL when
LOG_USER is specified.
2005-06-15 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs: s/LOG_USRE/LOG_USER/. Fixes #75274.
Thanks to Martin Honermeyer.
2005-06-09 Jonathan Pryor <jonpryor@vt.edu>
* make-map.cs: Look for [Obsolete] members, and mark the UnixConvert
conversion functions with the same [Obsolete] message. This should permit
more graceful deprecation of enumerations in the future (rather than just
API breaks).
2005-06-08 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs: Add execvp(2). (This should have been added with the other
exec(2) additions...).
2005-06-08 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs: Update comment with correct exception type.
* UnixConvert.cs: Rename ToFilePermissions(string) to
FromOctalPermissionString; Add ToOctalPermissionString,
FromUnixPermissionString, ToUnixPermissionString.
* UnixMarshal.cs: Remove ErrorMarshal.HaveStrerror_r and
UnixMarshal.IsErrorDescriptionThreadSafe. strerror(3) is now thread-safe
(from managed code, at least). Update comment.
2005-06-07 Jonathan Pryor <jonpryor@vt.edu>
* UnixFileSystemInfo.cs: Don't use lstat(2), use stat(2). This fits with
expectations better -- if you create a UnixFileInfo() on a symlink, you
want to get the target's information, not the symlink's info. Add
GetFileStatus so UnixSymbolicLinkInfo can override this behavior.
* UnixSymbolicLinkInfo.cs: Implement GetFileStatus() (which calls lstat(2)).
2005-06-07 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs: Document naming conventions.
2005-06-05 Jonathan Pryor <jonpryor@vt.edu>
* make-map.cs: Change automatic "ifdef HAVE_<header>" support prefix to
"ah:" from ">". I hadn't known about ">", and "ah:" is (somewhat) more
obvious.
* Syscall.cs: Change IncludeAttribute to put all headers/defines one/line.
It's easier to read this way. Add "ah:sys/xattr.h" to the headers.
2005-06-03 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: Add sanity checking to snprintf(3) to avoid buffer overflows.
2005-06-02 Jonathan Pryor <jonpryor@vt.edu>
* StdioFileStream.cs: Remove FilePosition property & replace with
SaveFilePosition/RestoreFilePosition methods. Since FilePosition has a
finalizer, it's not right to have implicitly created instances.
* Stdlib.cs:
- FilePosition: GC.SuppressFinalize() should be last in Dispose()
(following .NET guidelines).
- Syscall: Add locking around functions most likely to be thread unsafe.
This should provide some level of thread-safety to managed code.
* Syscall.cs: Add locking around functions most likely to be thread unsafe;
add mkstemp(3) export.
* UnixEnvironment.cs: GetUserShells should be atomic (from managed code).
* UnixGroup.cs: GetLocalGroups should be atomic (from managed code).
* UnixGroupInfo.cs: Add ToGroup() method to retrieve underlying Group info.
* UnixUser.cs: GetLocalUsers should be atomic (from managed code).
* UnixUserInfo.cs: Add ToPasswd () method to retrieve underlying Passwd info.
* UnixDriveInfo.cs: GetDrives should be atomic (from managed code).
2005-05-31 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: Add comment for atexit(3) so I don't try to add it.
* Syscall.cs: Add fcntl(2) overload which takes DirectoryNotifyFlags (so
that *something* accepts a DirectoryNotifyFlags); Fix IncludeAttribute
header files (">sys/poll.h" doesn't exist);
Add additional <sys/mman.h> functions mmap, munmap, msync, mlock, munlock,
mlockall, munlockall, mremap, mincore, remap_file_pages.
* UnixConvert.cs: Add conversion functions for MmapFlags, MmapProt, MsyncFlags,
MlockallFlags, MremapFlags.
2005-05-31 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs, UnixConvert.cs: Rename LockFlags to LockfCommand. This is a more
consistent naming, and it's more correct (they weren't flags in the first place).
2005-05-18 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: Correct Mono_Posix_Stdlib_InvokeSignalHandler export.
2005-05-18 Jonathan Pryor <jonpryor@vt.edu>
* make-map.cs: Process the Mono.Posix namespace as well as Mono.Unix; add
mapping for Boolean => int for native type conversion.
2005-05-18 Jonathan Pryor <jonpryor@vt.edu>
* make-map.cs: Add a MphPrototypeFileGenerator, which looks for DllImport
methods across all types and generates a C header file declaration for
those methods. This allows us to ensure consistency between
Mono.Posix.dll and MonoPosixHelper.so. Rename WrapperFileGenerator to
ConvertFileGenerator (it generates UnixConvert).
* MapAttribute.cs, IncludeAttribute.cs: Make these internal -- there's no
reason for external users to even know these exist.
* StdioFileStream.cs: Move GC.SuppressFinalize call to be last Dispose()
call. This follows current design guidelines, and allows an exception to
be thrown from Dispose() without un-registering the finalizer.
* Syscall.cs: Change method declarations to match MonoPosixHelper, etc.
- posix_fallocate(P) takes a size_t
- mis-spelled settimeofday(2), sethostname(2)
- exec(2) can be public; it's safe to call
- change lseek(2) so int's are passed to MonoPosixHelper.so, not shorts
- We can't allow two incompatible prototypes to exist (since C allows
only one prototype, and we're cross-checking prototypes now). Change
utime(2) so only one prototype is needed.
* UnixMarshal.cs: ErrorMarshal.ErrorTranslator and ErrorMarshal.Translate
shouldn't be public; make them internal.
* UnixStream.cs: Remove `unsafe` code block when a "safe" alternative works;
Close() should also call GC.SuppressFinalize.
2005-05-12 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs: The Statvfs structure should contain a MountFlags enumeration,
not a ulong (we can "safely" do this since POSIX defines some values for
f_flag, so we should be kind and expose them).
* UnixConvert.cs: Add MountFlags conversion functions.
2005-05-02 Joe Shaw <joeshaw@novell.com>
* UnixListener.cs (Init): Remove the call to Cleanup() and the
method itself, which was not supposed to be here. We try to
connect to the socket if it exists instead of deleting it
undconditionally.
2005-04-30 Ben Maurer <bmaurer@ximian.com>
* Stdlib.cs: Comment out usage of `UnmanagedFunctionPointer'. It
isn't supported in the runtime -- it throws an assert -- so better
not to use it at all for now.
2005-04-29 Jonathan Pryor <jonpryor@vt.edu>
* UnixConvert.cs: Fix time_t -> DateTime conversions. time_t should be
assumed to be in the local time zone, so don't mess with UTC shifts.
This allows Mono.Unix to produce sane output (e.g. identical to ls(1) or
stat(1), instead of several hours different).
2005-04-29 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: Make FilePosition slightly more useful by providing a
ToString() override which dumps the fpos_t structure contents into a
hex string. Add Equals(), GetHashCode(), operator==, and operator!=
so FilePosition behaves like a value type.
2005-04-21 Gonzalo Paniagua Javier <gonzalo@ximian.com>
* UnixClient.cs:
* UnixListener.cs: TcpListener/TcpClient clones from Jow Shaw.
2005-04-21 Gonzalo Paniagua Javier <gonzalo@ximian.com>
* Mono.Posix.dll.sources: added UnixListener and UnixClient from Joe
Shaw.
2005-04-21 Gonzalo Paniagua Javier <gonzalo@ximian.com>
* UnixEndPoint.cs: fix from Mono.Posix.
2005-04-20 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs: Make all fork(2) and exec(2) functions `private`. It
currently isn't safe to call these under *any* circumstances. See also
68141, and this pertinent quote from Butenhof's
"Programming with POSIX Threads", p197, s6.1:
"When a threaded process calls fork to create a child process,
Pthreads specifies that only the thread calling fork exists in the
child. ... Pthreads does not 'terminate' the other threads in a forked
process...They simply cease to exist. ... This is not a problem if
the child process is about to call exec to run a new program, but if
you use fork to clone a threaded program, beware that you may lose
access to memory, especially heap memory stored only as
thread-specific data values."
Since P/Invoke currently requires using thread local storage, once you
fork(2) you won't be able to invoke exec(2) from managed code (since that
would require a P/Invoke transition to call exec(2), which would require
TLS, which doesn't exist in the new process).
This can only be fixed by removing the TLS dependency on P/Invoke, which
isn't a priority (and may not be possible).
The workaround is to create a C function which does your fork(2)/exec(2)
(and any other functions such as daemon(3)) on your behalf, and P/Invoke
to call this C function.
2005-04-18 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs: Update comment specifying which functions belong in Syscall.
* UnixConvert.cs: Add XattrFlags conversion functions.
* UnixMarshal.cs: Remove warning about self-assignment.
2005-04-16 Daniel Drake <dsd@gentoo.org>
* Syscall.cs: Add bindings for extended attribute manipulation
2005-04-05 Miguel de Icaza <miguel@novell.com>
* Syscall.cs: Set entry point for sys_syslog to be syslog.
Include the syslog.h header in the generated map so that we
actually do the mapping.
2005-03-28 Jonathan Pryor <jonpryor@vt.edu>
* UnixConvert.cs: Add ToFopenMode() methods, which convert FileMode/FileAccess
into an fopen(3) mode string. ToOpenFlags() should throw
ArgumentOutOfRangeException for argument violations.
* StdioFileStream.cs: Add constructor overloads accepting filename and
FileMode/FileAccess overloads; Compatibility fixes with regression tests;
remove IDisposable implementation since System.IO.Stream already
implements it (which calls Close() for us).
2005-03-17 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: Move Errno-related functionality into Stdlib from Syscall,
since (1) errno is part of C89, and (2) StdioFileStream will need it, and
StdioFileStream shouldn't use Syscall. Add [UnmanagedFunctionPointer]
attribute to SignalHandler for .NET 2.0 (since signal handlers use C
calling convention, not Stdcall).
* Syscall.cs: Move Errno-related functionality into Stdlib.
* UnixMarshal.cs: Use ERANGE not EPERM when figuring out appropriate
translator, since ERANGE is part of C99 and EPERM isn't. Use Stdlib
instead of Syscall for Errno-related functionality.
2005-02-02 Jonathan Pryor <jonpryor@vt.edu>
* UnixFile.cs: Cope with changes in UnixStream.
* UnixStream.cs: Change FileDescriptor property to Handle for consistency.
* StdioFileStream.cs: Change FileStream property to Handle for consistency.
2005-02-02 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs: Remove public sys_ methods. Some were public by mistake, and
others so that users could manually marshal strings if desired. Manually
marshaling strings shouldn't be necessary, though, so remove them too.
2005-02-02 Jonathan Pryor <jonpryor@vt.edu>
* StdioFileStream.cs: Fix Length property to actually return the size of the
file, not the # of bytes from the current position to EOF. Oops.
2005-01-31 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: Import "msvcrt", not "libc". These members are part of the
ANSI C standard, and thus should be present on Windows via msvcrt.dll
(except snprintf, until they catch up to C99). Change the calling
convention of all functions to Cdecl, as the .NET default is Stdcall.
Changing the calling convention isn't needed in Syscall, as it can only be
run on Unix platforms anyway, where the default is Cdecl.
* Syscall.cs: Add LIBC member that points to the real "libc"; we can't use
the imported definition from Stdlib as "msvcrt" doesn't exist on Unix.
2005-01-29 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: sys_* functions shouldn't be public.
2005-01-13 Jonathan Pryor <jonpryor@vt.edu>
* make-map.cs: libMonoPosixHelper exports Mono_Posix prefixes, not Mono_Unix
prefixes, so change the type and namespace to generate compatible code.
* Syscall.cs: Change OpenFlags values so they match the Linux values.
2005-01-13 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: Use Stdlib.LIBC instead of "libc".
* StdioFileStream.cs: Add FilePosition property (not that I expect anyone to
use it) and Rewind() method.
2005-01-05 Jonathan Pryor <jonpryor@vt.edu>
* StdioFileStream.cs: Added; System.IO.Stream wrapper for C FILE struct.
* Stdlib.cs: Correct visibility of ftell().
2005-01-05 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: Re-order declarations to match the order used in the
C99 Standard Annex B; Complete <stdio.h> exports (except for those not
worth supporting); Add non-"unsafe" versions of fread(3), fwrite(3) and
add some rudimentary buffer-overflow checking; Add <stdlib.h> exports such
as getenv(3), exit(3), rand(3), EXIT_SUCCESS, RAND_MAX, etc.
2005-01-03 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs: Update endfsent() and setfsent() declarations, as these must
now be implemented in MonoPosixHelper.
2005-01-01 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs, Syscall.cs: Minimize duplicate declarations of
"MonoPosixHelper" for use in DllImport statements.
2005-01-01 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: Don't use C# v2 features; fixes build under CSC.EXE.
2004-12-30 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: On miguel's suggestion, rename Sighandler_t to SignalHandler.
2004-12-30 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: Implement all C89 <stdio.h> functions except for the scanf(3)
family. These are too dangerous to expose.
2004-12-30 Jonathan Pryor <jonpryor@vt.edu>
* CdeclFunctions.cs: Remove warning about unused variable.
* Stdlib.cs: Make signal(2) sane and (hopefully) complete.
* Syscall.cs: Fix cuserid Obsolete message to reference correct class name.
* UnixProcess.cs: Remove warning about unused variable.
* UnixMarshal.cs: Remove warnings about unused variables.
2004-12-29 Jonathan Pryor <jonpryor@vt.edu>
* UnixPath.cs: Add ReadSymbolicLink(), which takes an intelligent approach
to reading symlinks (since their contents may be any size, we grow the
buffer dynamically to fit them all, instead of assuming a maximum size).
* UnixSymbolicLinkInfo.cs: Remove MaxContentsSize.
2004-12-29 Jonathan Pryor <jonpryor@vt.edu>
* UnixPath.cs: Add check for when symlink points to a full path name.
2004-12-29 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs: Fix Object.Equals implementations.
* UnixPath.cs: New & improved, with Testing! GetRealPath() is changed so
that it doesn't walk the entire path looking for symlinks, it just reads
the leaf. GetCompletRealPath() walks the entire path resolving symlinks.
GetCanonicalPath() added, which "cleans up" a path (removing extraneous
"." and ".." entries).
* UnixSymbolicLinkInfo.cs: Rename ContentsLength -> MaxContentsSize.
2004-12-28 Jonathan Pryor <jonpryor@vt.edu>
* UnixFileSystemInfo.cs: Add a link(2) wrapper, CreateLink(). Strictly
speaking it's only "safe" to do this on files, but an exception will be
returned if the user tries to hard link directories (because of EPERM),
unless the user is root, in which case it should be allowed anyway...
2004-12-28 Jonathan Pryor <jonpryor@vt.edu>
* CdeclFunctions.cs: Correct the comments for AMD64
* UnixDirectoryInfo.cs: override Name; add Parent & Root properties;
Correct Path usage (s/Path/FullPath/g).
* UnixDriveInfo.cs: Added. Based on .NET 2.0 System.IO.DriveInfo docs,
provides statvfs(2) and getfsfile(3) information about a mounted volume.
GetDrives() wraps getfsent(3), thus parsing /etc/fstab.
* UnixFile.cs: Use UnixConver.ToOpenFlags, deleting the local version.
* UnixFileInfo.cs: Use UnixConver.ToOpenFlags, deleting the local version;
override Name; add DirectoryName and Directory properties;
* UnixFileSystemInfo.cs: Make more .NET-like, using FullPath and
OriginalPath protected members, abstract Name property; Add
CreateSymbolicLink; Remove ReadLink (it's now
UnixSymbolicLinkInfo.Contents); Use lstat(2) for Create(string), so we
properly detect Symbolic Links.
* UnixPath.cs: Added; Path manipulation utility functions.
* UnixSymbolicLinkInfo.cs:
- Seal the class;
- override new abstract member Name;
- rename ReadLink to ContentsPath (and Contents) properties
(why "Contents"? Because readlink(2) says "readlink places the
contents of the symbolic link in the buffer...")
- Add CreateSymbolicLinkTo(), which creates a symlink to the specified
"normal" file
2004-12-28 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: Add syslog(3) to XPrintfFunctions; Add additional printf(3)
and fprintf(3) overload which properly escape the format string
(by using "%s" as the format for the user-supplied message).
* Syscall.cs: Add #regions for enummerations, structures, classes; Wrap
syslog(3) and related enumerations; fix operator!= on Dirent, Group;
wrap {f}statvfs(2); wrap <fstab.h> entries (getfsent(3), etc.).
* UnixConvert.cs: Add Syslog-releated enumeration translation functions;
Move ToOpenFlags here from UnixFile and UnixFileInfo.
* UnixMarshal.cs: Missing P/Invoke methods throw
EntryPointNotFoundException, not MissingMethodException; add
EscapeFormatString, which escapes printf-style format strings so that they
can be safely handed off to native code (avoiding stack overflow, etc);
make CreateExceptionForError internal.
2004-12-15 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: Add more <stdio.h> wrappers, such as fread(3) and fwrite(3).
These will be useful in implementing System.IO.Stream subclass for
reading/writing to a FILE*. Fix a typo in the realloc(3) DllImport.
* Syscall.cs: Fix the sys_kill and sys_crypt declarations.
* CdeclFunction.cs: Document calling convention problems on AMD64.
2004-11-18 Jonathan Pryor <jonpryor@vt.edu>
* CdeclFunction.cs: Added.
* Stdlib.cs: Re-add printf(3) and fprintf(3). They may not be portable (the
jury is still out on that; the AMD64 SysV ABI looks like it should be
portable to AMD64 to my eyes), but they will work on *some* platforms, so
we should permit it. The new implementation takes a page out of
cocoa-sharp: use System.Reflection.Emit to generate a P/Invoke method at
runtime to invoke printf(3) or fprintf(3). This way, we can export a
params signature to C# code, permitting natural usage such as:
Stdlib.printf ("Hello, %s world! (%i)\n", "silly", 42);
* Syscall.cs: Mark which headers are complete, which functions still need
wrapping (for headers which have anything done to them), add #region
blocks for each header;
export mkfifo(3), fexecve(), getppid(2), setlogin(); fix sleep(3) export.
* UnixEnvironment.cs: Export a friendly getppid(2) wrapper.
GetParentProcessId isn't in UnixProcess as there's no way (that I know of)
to get the Parent's Parent, so it can't be a class member, and exposing it
as a static member of UnixProcess doesn't make sense to me, as it isn't
general. Added GetUserShells().
* UnixProcess.cs: Change constructor to internal, so it can be used from
UnixEnvironment.
2004-11-16 Jonathan Pryor <jonpryor@vt.edu>
* Stdlib.cs: Remove printf(3) and fprintf(3). These are vararg/CDECL
functions, and it's not portable to call them in this manner.
(It's not portable because some architectures, such as AMD64, use a
"cookie" as part of the vararg calling sequence to help reduce buffer
overflow exploits. Trying to call vararg functions as if they were an
overloaded function will not properly set this hardware cookie, resulting
in a hardware exception. Talk to lupus for more information.)
2004-11-16 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs, UnixConvert.cs: Remove mount- and umount-related
functionality. Mount/umount is inherently non-portable (see the C code
for mount/umount), and trying to provide a consistent interface is
impossible. If you need mount/umount support, use the command-line
programs mount(1) and umount(1).
2004-11-16 Jonathan Pryor <jonpryor@vt.edu>
+ Lots o' Renames, as the namespace changed.
* PosixConvert.cs: Moved to UnixConvert.cs:
* PosixDirectory.cs: Moved to UnixDirectory.cs:
* PosixEnvironment.cs: Moved to UnixEnvironment.cs:
* PosixDirectoryInfo.cs: Moved to UnixDirectoryInfo.cs:
* PosixFile.cs: Moved to UnixFile.cs:

* PosixProcess.cs: Moved to UnixProcess.cs:
* PosixStream.cs: Moved to UnixStream.cs:
* PosixSymbolicLinkInfo.cs: Moved to UnixSymbolicLinkInfo.cs:
* PosixUser.cs: Moved to UnixUser.cs:
* PosixUserInfo.cs: Moved to UnixUserInfo.cs:
* Catalog.cs, IncludeAttribute.cs, MapAttribute.cs, PeerCred.cs, Stdlib.cs,
Syscall.cs, UnixConvert.cs, UnixDirectory.cs, UnixDirectoryInfo.cs,
UnixEndPoint.cs, UnixEnvironment.cs, UnixFile.cs, UnixFileInfo.cs,
UnixFileSystemInfo.cs, UnixGroup.cs, UnixGroupInfo.cs, UnixIOException.cs,
UnixMarshal.cs, UnixProcess.cs, UnixStream.cs, UnixSymbolicLinkInfo.cs,
UnixUser.cs, UnixUserInfo.cs: Deal with renamed classes/members.
2004-11-15 Jonathan Pryor <jonpryor@vt.edu>
* PosixUserInfo.cs: Make the PosixUserInfo(Passwd) constructor public;
override Object.GetHashCode and Object.Equals.
* PosixGroupInfo.cs: Make the PosixGroupInfo(Group) constructor public;
override Object.GetHashCode and Object.Equals.
* PosixIOException.cs: Use PosixMarshal.GetErrorDescription instead of
calling Syscall.strerror_r directly
* PosixMarshal.cs: Add GetErrorDescription. Strerror_r() isn't portable, so
GetErrorDescription() first tries strerror_r(), and if it fails falls back
to strerror(3).
* Syscall.cs:
- Seal the Dirent class. It has no virtual members, so there's no point
in it being non-sealed. Override Object.GetHashCode and Object.Equals.
- Seal the Group class. It has no virtual members, so there's no point
in it being non-sealed. Override Object.GetHashCode and Object.Equals.
Provide operator== and operator!=.
- Seal the Passwd class. It has no virtual members, so there's no point
in it being non-sealed. Override Object.GetHashCode and Object.Equals.
Provide operator== and operator!=.
- Remove strerror_r() convenience overload. This is now
PosixMarshal.GetErrorDescription().
2004-11-12 Jonathan Pryor <jonpryor@vt.edu>
* Syscall.cs: Export time-related functions (gettimeofday, settimeofday,
utime, utimes), mknod.
2004-11-07 Atsushi Enomoto <atsushi@ximian.com>
* PosixEnvironment.cs : csc build fix. see bug #69195.
* PosixStream.cs : csc build fix. see bug #69196.
2004-11-05 Jonathan Pryor <jonpryor@vt.edu>
* PosixConvert.cs: New file; conversion functions for Mono.Posix types.
* PosixDirectory.cs: New file; Friendly wrapper over directory information.
* PosixDirectoryInfo.cs: New file; Friendly wrapper over directory information.
* PosixEnvironment.cs: New file; Friendly wrapper over environment information.
* PosixFile.cs: New file; Friendly wrapper over file information.
* PosixFileInfo.cs: New file; Friendly wrapper over file information.
* PosixFileSystemInfo.cs: New file; Friendly wrapper over `stat'.
* PosixGroup.cs: New file; User Group-related functionality
* PosixGroupInfo.cs: New file; User Group-related functionality
* PosixIOException.cs: New file; Exception for POSIX-generated exceptions.
* PosixMarshal.cs: New file; utility functions for marshaling, etc.
* PosixProcess.cs: New file; Friendly wrapper over process information.
* PosixStream.cs: New file; Friendly wrapper over file descriptors.
* PosixSymbolicLinkInfo.cs: New file; Friendly wrapper over symbolic links.
* PosixUser.cs: New file; Friendly wrapper over user information.
* PosixUserInfo.cs: New file; Friendly wrapper over user information.
* Stdlib.cs: New file; C standard library exports.
* Syscall.cs: Effective re-write.
- Organize exports by header file
- add additional enumerations (Error for the E* error values, etc.)
- always explicitly specify enumeration underlying type
- Use a new wrapping infrastructure so that ABI-stable types are exported
- For example, size_t is exported as ulong, not IntPtr.
- Wrap more functions, and wrap them better (such as getpwnam).
- This release is NOT backward compatible. Many names are the same, and
hopefully they're still compatible, but no effort was made to maintain
compatibility. For example, FileMode was removed and replaced with
FilePermissions, to avoid a name conflict with System.IO.FileMode.
- Change umount() to use MonoPosixHelper: portability fix for Mac OS X.
* make-map.cs: Another effective re-write, to clean up the code, produce
better output, and produce more output. For example, most of
PosixConvert can be auto-generated, so it is (modulo version delays and
bootstrap issues). `map.c' is now conditional on all macros, and has
error checking for invalid/unsupported values.
2004-09-18 Jackson Harper <jackson@ximian.com>
* Syscall.cs: Add support for poll ().
2004-09-18 Jackson Harper <jackson@ximian.com>
* make-map.cs: Use field value not name for #defines.
2004-09-14 Loren Bandiera <lorenb@mmgsecurity.com>
* Syscall.cs: Added method for getpwnam which uses Passwd
struct.

* Syscall.cs: Removed argument to getgid that shouldn't be there.
Added getusername, getgroupname which wrap getpwuid, getgrgid

Added stat and lstat, which use StatMode enumeration
(like FileMode but nicer and complete) and Stat struct.
