Each port that allows the usage of dynamic libraries should call InitSystemDynLibs during initialization of the System unit.
The DynLibs unit has been adjusted to be a forwarder for the functions that now reside in the System unit (for backwards compatiblity just in case). Additionally the unit will register the DynLibsManager if it doesn't reside in the System unit anyway.
Currently only the Windows targets (Win32, Win64 and WinCE) implement the DynLibsManager inside the System unit. For other systems using the LoadLibrary, etc. functions will lead to a run error/exception.
If a port wants to implement its own DynLibsManager then it needs to define DISABLE_NO_DYNLIBS_MANAGER. TLibHandle, NilHandle and optionally TOrdinalEntry (it's set to SizeUInt otherwise) should be defined in sysdlh.inc which needs to be enabled using the define FPC_SYSTEM_HAS_SYSDLH (because there are targets which have FEATURE_DYNLIBS enabled, but don't support them... e.g. powerpc-wii -.-).
The DynLibsManager contains methods for loading a library based on a RawByteString and based on a UnicodeString. BOTH should be implemented, but internally one can forward to the other.
The loading by ordinal *can* be be implemented. If it is set to Nil then the implementation of GetProcAddress(lib,ordinal) will return Nil.
+ new functions SetDynLibsManager and GetDynLibsManager to set and retrieve the current DynLibsManager
* provide interface of DynLibs unit in unit System

- fixed all Amiga-like system units to not leak the last directory
lock while changing back to the original dir in System_exit;
(a bug found by Marcus Sackrow, thanks!)
* renamed AOS_origDir to ASYS_origDir
git-svn-id: trunk@28537 -
o these routines are now generic wrappers in filutil.inc, and call
the platform-dependent internalfindfirst/next/close routines
o on unix, the fnmatch routine got proper support for UTF-8 matching
(e.g., it won't match a partial UTF-8 code point to a "?" wildcard)
o for NativeNT, a similar (untested) UTF-16 version has been added
+ test for the above
* rawbytestring/unicodestring versions of fileage
git-svn-id: branches/cpstrrtl@25302 -
+ codepage support for textrec/filerec and the above routines
* textrec/filerec now store the filename by default using widechar. It is
possible to switch back to ansichars using the FPC_ANSI_TEXTFILEREC define.
In that case, from now on the filename will always be stored in
DefaultFileSystemEncoding
* fixed potential buffer overflows and non-null-terminated file names in
textrec/filerec
+ dodirseparators(pwidechar), changed the dodirseparators(pchar/pwidechar)
parameters into var-parameters and gave those routines an extra parameter
that indicates whether the p(wide)char can be changed in place if
necessary or whether a copy must be made first (avoids us having to make
all strings always unique everywhere, because they might be changed on
some platforms via a pchar)
* do_open/do_erase/do_rename got extra boolean parameters indicating whether
the passed pchars point to data that can be freely changed (to pass on to
dodirseparators() if applicable)
* objects.pp: force assign(pchar) to be called, because
assign(array[0..255]) cannot choose between pchar and rawbytestring
versions (and removing the pchar version means that assign(pchar) will
be mapped to assign(shortstring) in {$h-})
* fixed up some routines in other units that depend on the format of
the textrec/filerec.name field
git-svn-id: branches/cpstrrtl@25137 -
so declarations can also depend on it and similar defines (not yet the
case)
+ added SYSUTILS_HAS_ANSISTR_ENVVAR_IMPL/SYSUTILS_HAS_UNICODESTR_ENVVAR_IMPL
to indicate whether the platform-dependent part of the unit provides
an ansistring/unicodestring interface to get environment variables
+ Windows version of getenvironmentvariable(unicodestring)
+ generic ansistring/unicodestring versions of GetEnvironmentVariable()
in case the platform doesn't provide them
* result of GetEnvironmentString() is ansistring/unicodestring depending
on the state of the FPC_RTL_UNICODE define
git-svn-id: branches/cpstrrtl@25116 -
CreateDir and RemoveDir, and implemented a generic one (based on the OS/2
version) in the shared sysutils code (so that the filesystem code page
support for the system unit routines can be reused)
* include both ansistring and unicodestring versions of the above routines,
and of ForceDirectories. Exception: GetCurrentDir, which cannot be
overloaded based on function result and whose return type currently
dependends on the FPC_UNICODE_RTL define
git-svn-id: branches/cpstrrtl@25113 -
* renamed platform-specific pchar versions of those rouines to do_*() and
changed them to either rawbytestring or unicodestring depending on the
FPCRTL_FILESYSTEM_SINGLE_BYTE_API/FPCRTL_FILESYSTEM_TWO_BYTE_API setting
* implemented generic shortstring versions of those routines on top of either
rawbytestring or unicodestring depending on the API-kind (in case of the
embedded target, if ansistring are not supported they will map directly
to shortstring routines instead)
* all platform-specific *dir() routines with rawbytestring parameters now
receive their parameters in DefaultFileSystemCodePage
- removed no longer required ansistring variants from the objpas unit
- removed no longer required FPC_SYS_MKDIR etc aliases
* factored out empty string and inoutres<>0 checks from platform-specific
*dir() routines to generic ones
o platform-specific notes:
o amiga/morphos: check new pathconv(rawbytestring) function
o macos TODO: convert PathArgToFSSpec (and the routines it calls) to
rawbytestring
o nativent: added SysUnicodeStringToNtStr() function
o wii: convert dirio callbacks to use rawbytestring to avoid conversion
+ test for unicode mk/ch/rm/getdir()
git-svn-id: branches/cpstrrtl@25048 -
getdir(rawbytestring):rawbytestring so it can accept strings in any
encoding and cleanly return results in DefaultRTLFileSystemCodePage
+ getdir(unicodestring):unicodestring
* renamed the getdir implementation of all platforms except for embedded-
without-ansistring-support to do_getdir(), and depending on the
FPCRTL_FILESYSTEM_SINGLE_BYTE_API/FPCRTL_FILESYSTEM_TWO_BYTE_API define
changed its shortstring parameter to ansistring or unicodestring. The
do_getdir(rawbytestring) routine should just set the code page of the
return value to DefaultFileSystemCodePage without conversion (not
DefaultRTLFileSystemCodePage with conversion, that conversion is performed
in getdir if necessary; this avoids double conversions in case
getdir(unicodestring) is called)
+ generic getdir(shortstring) for platforms supporting either ansistrings or widestrings
o platform maintainers:
o OS/2: adjust code to supports paths > 255 characters if those are supported
o Wii: adjust used callback to use rawbytestring to support paths > 255 characters and
avoid shortstring->rawbytestring conversion overhead
o Windows: GetCurrentDirectoryW is now always used (to prevent data loss)
git-svn-id: branches/cpstrrtl@24993 -
use a single byte API for file system operations
+ FPCRTL_FILESYSTEM_TWO_BYTE_API define that is set for targets where we
use a single byte API for file system operations
o in principle, both can be set if both are supprted and implemented in
the RTL in order to minimise conversions depending on the scenario
git-svn-id: branches/cpstrrtl@24991 -
o resolved conflict in updated morphos sysutils unit
o moved code that had been added to the now deleted sysunix.inc to the
unix-specific block of the fpwidestring unit's init code
git-svn-id: branches/cpstrrtl@24913 -
Especially for the introduction of the Queue method the internal Synchronize handling was modified. Instead of handling only one event there is now a queue of events which is walked completely when CheckSynchronize is called. Each entry in the queue can carry a PRTLEvent which will be signaled when the contained method has been executed and thus Synchronize methods can still be blocking.
Exceptions inside the queued methods are either handed back to the calling method for Synchronize events or raised directly (after leaving the queue in a valid state) to the caller of CheckSynchronize.
The way platform specific adjustments can be made to TThread was changed. Instead of implementing the Constructor and Destructor directly one now implements the methods SysCreate and SysDestroy which are called from the Constructor and Destructor respectively. All RTLs were adjusted for this and should be controlled by the platform maintainers for correct compilation (Unix works).
The new method NameThreadForDebugging has two overloaded variants: one with the thread name as AnsiString and one with the thread name as UnicodeString.
By default the AnsiString variant calls the UnicodeString variant and the latter needs to be implemented. This can be changed by defining THREADNAME_IS_ANSISTRING for a platform. Then the UnicodeString variant calls the AnsiString one and the AnsiString one needs to be implemented.
Also added was a global property CPUCount for the System unit. This property returns the number of virtual cores of the system.
New methods and functions that should be implemented per platform are:
System.GetCPUCount (default returns 1)
Classes.TThread.GetSystemTimes (default zeros the struct)
Classes.TThread.NameThreadForDebugging (default does nothing)
More detailed information about the added methods will be available in the feature announcement mail.

The WinCE implementation converts the rawbytestring arguments to
unicodestring and calls unicode OS APIs, while the others convert
unicodestring arguments to DefaultFileSystemCodePage and call
single byte OS APIs
+ test for the above
git-svn-id: branches/cpstrrtl@22467 -
RTL units. Comes with a FPCRTL_FILESYSTEM_UTF8 define that can be
activated for targets whose single byte filesystem interface enforces
UTF-8; included in inc/systemh.inc and unix/cwstring.pp until now
+ DefaultFileSystemCodePage variable that holds the code page used for
communicating with the OS single byte file system APIs, and for the
strings returned by those same APIs. Initialized with
o the result of GetACP in the system unit of Windows platforms, except for
WinCE which uses UTF-8 since its file system OS API calls already use
the UTF-16 versions
o CP_UTF8 on Unix platforms with FPCRTL_FILESYSTEM_UTF8 defined, and with
DefaultSystemCodePage on other Unix platforms
o DefaultSystemCodePage on Java/Android JVM targets
+ DefaultRTLFileSystemCodePage variable that holds the code page used to
encode strings returned by RTL routines that return filenames obtained
from OS API calls. By default the same as DefaultFileSystemCodePage on
all platforms. Separate from DefaultFileSystemCodePage for clarity on
platforms that may use either utf-16 or single byte OS API calls to
send/receive file names (such as most Windows platforms)
+ new scpFileSystemSingleByte enum that can be passed to
GetStandardCodePage() to get the default code page for OS single byte file
system APIs, with implementations for Unix and Windows
+ SetMultiByteFileSystemCodePage() procedure to override the value of
DefaultFileSystemCodePage
In principle, in the long run unchanged programs only using generic
ansistrings and unicodestrings should (mostly) behave the same as in
FPC 2.6.0 as far as RTL-level file system APIs are concerned if
they set DefaultFileSystemCodePage and DefaultRTLFileSystemCodePage
to DefaultSystemCodePage at the start of their execution
git-svn-id: branches/cpstrrtl@22466 -
o support for the new codepage-aware ansistrings in the jvm branch
o empty ansistrings are now always represented by a nil pointer rather than
by an empty string, because an empty string also has a code page which
can confuse code (although this will make ansistrings harder to use
in Java code)
o more string helpers code shared between the general and jvm rtl
o support for indexbyte/word in the jvm rtl (warning: first parameter
is an open array rather than an untyped parameter there, so
indexchar(pcharvar^,10,0) will be equivalent to
indexchar[pcharvar^],10,0) there, which is different from what is
intended; changing it to an untyped parameter wouldn't help though)
o default() support is not yet complete
o calling fpcres is currently broken due to limitations in
sysutils.executeprocess() regarding handling unix quoting and
the compiler using the same command lines for scripts and directly
calling external programs
o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
to the make command line

unicodestring = java.lang.String. The reason this was the default in
the past is that this was the first string type that was implemented,
and without it being the default most code involving string operations
would fail. Now the default strings types are the same as for other
targets
+ new {$modeswitch unicodestrings} directive, that when activated
*together* with {$h+},
1) changes char into an alias for widechar
2) changes string into an alias for unicodestring
3) changes the preferred string evaluation type (in case of uncertainty)
to unicodestring
{$modeswitch unicodestrings} with {$h-} does not change anything at all
regarding the string type (it still changes the char type)
+ new uuchar unit that redefines char as widechar, and which is automatically
included by the compiler if {$modeswitch unicodestrings} is enabled
git-svn-id: branches/jvmbackend@18781 -
change in utils/fpcm/fpcmake.ini in prevous commit.
Adapt also other files to that change:
* compiler/globals.pas: Replace $FPCTARGET by os_string if
tf_use_8_3 flag is set for target_info also.
* tests/Makefile.fpc: Modify TEST_TARGETSUFFIX in the same way
as TARGETSUFFIX was modified in previous commit.
* tests/utils/dotest.pp:
+ New variable UseOSOnly, set to true if only target OS name
should be used for subdirectories.
