Note an EINVAL result for this selector generally implies case-sensitive. This works nicely for hfs+ in the case-sensitive and insensitive variants. Unfortunately it looks like EINVAL is returned by smbfs and fat32, which are both case-insensitive, and ufs, which is case- sensitive. So I guess this test is only reliable when EINVAL is not returned (probably just for hfs-family filesystems). Any other suggestions? This email sent to site_archiver(a)lists.apple.com

setting malloc'd memory as executable on intel
by Chase 09 Apr '07

09 Apr '07

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com i'm creating a function on the fly (plain old c function). i set up the function pointer. i malloc enough memory for it and point the function pointer to it. i populate the function with code (including boilerplate stack setup/cleanup). when i inspect the code in memory at runtime, it looks perfect (and the function pointer is properly pointing to it). but i cannot call it or even jump into it using gdb's jump. i get "??" at the top of the call chain in xcode and nothing shows up in the assembly or code views in the debugger. when i hit the "Step Into Instruction" button, i get: Previous frame inner to this frame (corrupt stack?) Previous frame inner to this frame (corrupt stack?) (this is on intel, by the way) i tried MakeDataExecutable(), but it didn't help. and i tried msync(ptr, size, MS_INVALIDATE), but it didn't help either. what am i missing here? thanks. - Chase _______________________________________________ Do not post admin requests to the list.

Building PHP with GD...
by Morgan Aldridge 07 Apr '07

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Thanks for any insight and assistance you can provide, Morgan Aldridge -- morgant(a)makkintosshu.com http://www.makkintosshu.com/ _______________________________________________ Do not post admin requests to the list. They will be ignored. Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… I'm in need of having PHP built with GD support and it's been a while (Darwin 1.4.1 days, actually) since I've had to do so. My Xserve (Dual 2GHz G5) is running Mac OS X 10.4.8 Server (Darwin 8.8) and I've already got GD (and its prerequisites: libjpeg, libpng, zlib, etc.) built and working with Perl. So, I've obviously got to build PHP with the '--with-gd' option. Since I'm running the built-in Apache & PHP, PHP is version 4.4.1 (last updated in Darwin 8.6; http://www.opensource.apple.com/ darwinsource/10.4.6.ppc/apache_mod_php-18.4/) and was built with the following configure command: '/SourceCache/apache_mod_php/apache_mod_php-18.4/php/configure' '-- prefix=/usr' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '-- disable-dependency-tracking' '--with-apxs' '--with-ldap=/usr' '--with- kerberos=/usr' '--enable-cli' '--with-zlib-dir=/usr' '--enable-trans- sid' '--with-xml' '--enable-exif' '--enable-ftp' '--enable-mbstring' '--enable-mbregex' '--enable-dbx' '--enable-sockets' '--with-iodbc=/ usr' '--with-curl=/usr' '--with-config-file-path=/etc' '--sysconfdir=/ private/etc' '--with-mysql=/usr' '--with-mysql-sock=/var/mysql/ mysql.sock' So, my question is, if I rebuild the same version of PHP will I have to rebuild Apache (again, it's been a while and so I can't remember how the dependancy works)? If not, can I build a new copy with '-- prefix=/usr/local' and still have it to work with the built-in apache or will I have to replace the built-in PHP (something I'd like to avoid)? Or, should I just be building a matching Apache & PHP in /usr/local and modifying the Startup Items and/or launchd jobs? If I rebuild the same versions will that break any of Server Admin.app and serveradmin's functionality? This email sent to site_archiver(a)lists.apple.com

simple ASL question

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com -steve _______________________________________________ Do not post admin requests to the list. They will be ignored. Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… Hey, I'm using ASL to read the log files. Very cool, but there seems to be some missing functionality. How can I get notified when the log file changes? I don't want to kqueue the asl.db file (since that seems like an implementation detail I shouldn't rely on). Is that the solution. Also, If anyone cares to know, ASL corrupts memory on Tiger and is unusable. Is that a known issue? run code with /usr/lib/ libgmalloc.dylib and it crashes everytime. Randomly corrupts ram and randomly bombs otherwise. steve(a)cocoatech.com (email me directly if you have an answer, I rarely read these lists) This email sent to site_archiver(a)lists.apple.com
