[Issue 1550] D DLLs close standard input/output streams when unloading
http://d.puremagic.com/issues/show_bug.cgi?id=1550 Rainer Schuetze r.sagita...@gmx.de changed: What|Removed |Added CC||r.sagita...@gmx.de --- Comment #2 from Rainer Schuetze r.sagita...@gmx.de 2010-04-07 11:20:55 PDT --- The workaround (setting _fcloseallp = null) also prevents any other open file from being closed. I think it should be fixed in the C-runtime library, where the handle for stdin/out/err is taken from a call to GetStdHandle(), and probably should not be closed when terminating. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
[Issue 4071] Missing support to share memory and objects between DLLs and executable
http://d.puremagic.com/issues/show_bug.cgi?id=4071 --- Comment #1 from Rainer Schuetze r.sagita...@gmx.de 2010-04-07 11:40:36 PDT --- Created an attachment (id=600) add options -exportall and -sharedlib to dmd Let's start with a few patches to dmd: 1. add option -exportall to export any mangled symbol defined by an object file (a workaround for #3956 is needed, patching obj_export to avoid indeterministic removal of leading '_' from exported symbols by optlink) 2. add option -sharedlib to switch to different default libraries phobos_shared.lib and snn_shared.lib instead of phobos.lib and snn.lib -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

http://d.puremagic.com/issues/show_bug.cgi?id=4071 --- Comment #2 from Rainer Schuetze r.sagita...@gmx.de 2010-04-07 11:47:04 PDT --- Created an attachment (id=601) druntime support for building phobos.dll The major changes are in druntime and involve splitting files into the part that can be shared in a single DLL and the functions that must exist per binary: - move moduleCtor/Dtor, etc. from object_.di into new file moduleinit.d (had to copy some ModuleInfo (back?) declarations to object.di to compile) - move extern(C) main() from dmain2.d into new file cmain.d - exclude __LDBLULLNG() in llmath.d because it is already in snn.lib - build druntime.obj with -exportall instead of druntime.lib excluding moduleinit.d, cmain.d and a few more - extracted stuff from dll_helper.d into new file shared_dll_helper.d and added a few more functions to support patching relocations -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

http://d.puremagic.com/issues/show_bug.cgi?id=4071 --- Comment #3 from Rainer Schuetze r.sagita...@gmx.de 2010-04-07 11:54:49 PDT --- Created an attachment (id=602) changes to phobos to build phobos.dll The patches to phobos are more-or-less limited to the makefile and adding 2 files: - phobos: build phobos.obj with -exportall instead of phobos.lib - add def-file exporting any sensible symbol from the C compiled modules and snn.lib - add dllmain.d that works along the line of the new dll-support in dmd 2.042 - build phobos.dll from druntime.obj, C compiled modules and the object files not included in druntime.obj using the def-file - use implib to create import library phobos_shared.lib (the optlink /IMLIB creates a corrupted lib) - add modules to the lib that must exist in each binary: minit.obj, moduleinit.obj, cmain.obj, dll_helper.obj, etc. - extracted some modules from snn.lib (constart, dllstart, winstart, excptlst, cinit, ehinit, setargv, tlsdata, tlsseg, clearbss) and put them in new lib snn_shared.lib -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
[Issue 4071] Missing support to share memory and objects between DLLs and executable
http://d.puremagic.com/issues/show_bug.cgi?id=4071 --- Comment #4 from Rainer Schuetze r.sagita...@gmx.de 2010-04-07 12:00:45 PDT --- Created an attachment (id=603) example using the shared dll This is the example from dll.html modified to work with the shared DLL. Please note that an executable/DLL needs a slightly different initialization: - patch relocations to stubs to import table to the destination value to allow data symbols to be accessed correctly - do not init gc - inform gc about TLS usage - add check to module(tls)ctors to avoid calling modules in other dlls These are already covered by the patches to druntime. If you apply the patches, you might need to check the path to the tools at the top of the makefiles. current restrictions: - there is no global moduleinfo-array spanning all binaries - trace module not included (always produces output) - no version check, so welcome to DLL hell! -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

[Issue 4071] Missing support to share memory and objects between DLLs and executable
http://d.puremagic.com/issues/show_bug.cgi?id=4071 Jacob Carlborg d...@me.com changed: What|Removed |Added CC||d...@me.com --- Comment #6 from Jacob Carlborg d...@me.com 2010-04-07 13:08:02 PDT --- I have no experiences of DLLs but here are my experiences on converting Tango to a dynamic library on Mac OS X. Don't know if any of this would work on Windows. Comment 1 An option to build as an dynamic library would be nice Comment 2 The way I solved the problems here was to declare the D main function as a weak symbol in a C file. The module constructors are handled by looping through all loaded images (binaries, dynamic libraries) and collect the module info arrays. Then combining all the arrays into one and running all the module constructors. The same is done with the exception handling tables. The following have I not done yet, but I hope it will work: In a C file, declare a function to be a module initializer that initializes the D runtime if no D main function is present. Don't know if this helps anything. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
