Use dynamic allocation to be able to deal with any length of name. commit 66c9847ad54b126ccafd4877292454ab57d0c115 Author: David Engraf <dogge2k@gmx.de> Date: Wed Jul 16 09:16:38 2008 -0500 Linux: correct usage of MAX_PATH Thanks to clarification from Artem Egorkine, MAX_PATH already includes space for the trailing NULL. commit 6494f07a6d1b73ce786ae581c4ff691e39e61d19 Author: Daniel Drake <dsd@gentoo.org> Date: Tue Jul 8 21:15:54 2008 -0500 Linux: fix bulk/iso transfer double-cancellation Reset counters to 0 so that it's possible to cancel a transfer twice without breaking things. Not sure that I want to support this properly, but this makes it work at least. commit 9140f5b414e37a3714cde9c6d6c87c963338a83a Author: Daniel Drake <dsd@gentoo.org> Date: Sat Jun 28 21:28:44 2008 -0500 v0.9.1 release commit 83a029062c1d2bfb584d7a6ee94915583d37464c Author: Daniel Drake <dsd@gentoo.org> Date: Sat Jun 28 21:24:49 2008 -0500 Add missing GET_CONTEXT() commit fbad9a5426f0369394c88987355a8fb06a741ca1 Author: Daniel Drake <dsd@gentoo.org> Date: Sat Jun 28 21:18:41 2008 -0500 Linux: Compatibility with new sysfs descriptors file As of 2.6.26, the descriptors file now includes all descriptors, not just the active one. commit 819e65f880ca43526036e56c65c415042c91f58f Author: Daniel Drake <dsd@gentoo.org> Date: Thu Jun 26 22:47:05 2008 -0500 Allow user data pointer to be passed through pollfd notification API commit 1df713d622ab4f0b03aad72d903ac7beb8fb3b90 Author: Daniel Drake <dsd@gentoo.org> Date: Tue Jun 24 23:01:51 2008 -0500 Introduce contexts to the API Suggested by David Zeuthen. This allows multiple libraries in the same process to independently use libusb without interfering. commit 9818151c60a85aea6af24cb0996a92c3726c9864 Author: Daniel Drake <dsd@gentoo.org> Date: Tue Jun 24 21:31:13 2008 -0500 Revert "Temporary workaround for event handling serialization issue" This reverts commit 2d3a1111caff40ebb87983c861ff548cdc9e5946. This was based on the assumption that dying threads would automatically release mutexes, which is not the case. commit d5f82893fab3f1c13b1af4ba17aac72479bad7d5 Author: Daniel Drake <dsd@gentoo.org> Date: Fri Jun 20 23:04:53 2008 -0500 Overflow handling commit 546dee211eefbdd280fd1fc9dee84a9b52105078 Author: Artem Egorkine <arteme@gmail.com> Date: Tue Jun 17 18:27:38 2008 -0500 a fix for SIGSEGV in handle_bulk_completion() We cannot dereference tpriv after calling usbi_handle_transfer_cancellation() because that function may invoke the user-supplied callback which may free the transfer. commit 947ba8056456a5215724fb502e3e09d50016f699 Author: Daniel Drake <dsd@gentoo.org> Date: Mon Jun 16 22:50:50 2008 -0500 Refine configuration selection again At Alan Stern's suggestion, just offer the bare "set configuration" and "get configuration" functionality, and let applications worry about the specific race conditions and unusual situations. commit e7a7a49d0331ee0e14145f6e7ec39763b36314ac Author: Daniel Drake <dsd@gentoo.org> Date: Sun Jun 15 15:29:38 2008 -0500 docs update Add a THANKS file, make copyright notices easily accessible, update TODO commit 217534e4b396081e038ee5f94c813d1668963673 Author: Daniel Drake <dsd@gentoo.org> Date: Sun Jun 15 15:23:29 2008 -0500 round up poll timeout Pointed out by Richard Röjfors, otherwise we end up busy-looping with a poll() timeout of 0. commit 5ad79b324bc5e11a75a585398a1e81c26f05e758 Author: Felipe Balbi <me@felipebalbi.com> Date: Sun Jun 8 12:34:48 2008 +0300 fix doc about libusb_open() libusb_open() returns int instead of libusb_device_handle. Signed-off-by: Felipe Balbi <me@felipebalbi.com> [dsd: small correction] commit 2d3a1111caff40ebb87983c861ff548cdc9e5946 Author: Daniel Drake <dsd@gentoo.org> Date: Thu May 29 17:26:26 2008 +0100 Temporary workaround for event handling serialization issue Ludovic Rousseau pointed out that libusb_unlock_events() is not called when a thread gets terminated with a signal, meaning that event waiters will not be woken up in this case. Add a temporary hack to libusb_event_handler_active() so that at least the other threads will realise on the next iteration of their event handling loop. The real fix will likely involve reworking most of this. commit 514bb8790cfe8b93ccfff82bc17081b1030acce0 Author: Daniel Drake <dsd@gentoo.org> Date: Thu May 29 12:35:01 2008 +0100 Refine libusb_set_configuration() semantics Applications will generally want to set a configuration before claiming interfaces. The problem is that the interface may already be set, and someone else may have claimed an interface (meaning that all calls to set_configuration will fail, even if it's for the same configuration). There are now 2 options: 1. Use the new libusb_get_configuration() to determine active configuration before calling libusb_set_configuration() 2. Or just call libusb_set_configuration() as usual, which will do nothing if that configuration is already active. commit d1292f8e7300051239a7ed2769d221dc7a6f9fca Author: Daniel Drake <dsd@gentoo.org> Date: Sun May 25 23:42:42 2008 +0100 v0.9.0 release First libusb-1.0 beta release commit 4cd249388e4ed2ca03f1263984ab67df5030bb65 Author: Daniel Drake <dsd@gentoo.org> Date: Sun May 25 22:59:09 2008 +0100 Take lock before raising event waiters condition This avoids a race between the user checking for active event handler and then blocking on the condition variable commit 7c525480ab3c4db9205bfe30bb0d2bef9096c444 Author: Daniel Drake <dsd@gentoo.org> Date: Fri May 23 15:57:07 2008 +0100 Implement serialization of event handlers Now offers a mechanism to wait for events while another thread is doing the event handling. Complicates things for MT async apps, but then again it's a bit of a tricky combination to start with. commit ff0660a415ecfd0879600eaad1c5899b6d93a30a Author: Daniel Drake <dsd@gentoo.org> Date: Sat May 24 21:28:31 2008 +0100 allow LIBUSB_DEBUG env var to control message verbosity at runtime Based on ideas from Ludovic Rousseau commit 4d788967e3f8d75eaf3a1ac1ee8e2e8bed0601c1 Author: Daniel Drake <dsd@gentoo.org> Date: Fri May 23 15:58:11 2008 +0100 don't print messages by default Add libusb_set_debug() API to set message verbosity. Ludovic Rousseau pointed out that applications may close stdout/stderr descriptors, which might then be reused. commit bef33bb9eba0da04ee7488d9cd5e6ab12bc61c0c Author: Daniel Drake <dsd@gentoo.org> Date: Mon May 19 15:43:27 2008 +0100 Fix memory leak in libusb_control_transfer Pointed out by David Engraf: we weren't freeing the transfer buffer commit a345bacb6f07ebb2122402041a9e8092d4a20a4d Author: David Engraf <david.engraf@netcom.eu> Date: Mon May 19 15:16:32 2008 +0100 Linux: fix handling of ioctl failure The return value of some ioctl commands in linux_usbfs.c are not handeled correct. The ioctl function returns != 0 and errno is set with the error code. commit e44396a458ecea9e5edd9a7577e617571c76860d Author: David Engraf <david.engraf@netcom.eu> Date: Mon May 19 15:13:38 2008 +0100 critical memory leak in handle_events This patch closes a critical memory leak in handle_events. The fds variable is malloced but never freed. When I'm calling handle_events with a timeout of 0, my system runs out of memory after a few seconds. commit eb25630f52bc9848b444e439632c899977d887b0 Author: Daniel Drake <dsd@gentoo.org> Date: Fri May 16 23:50:20 2008 +0100 More informative libusb_open() return code Hopefully one of the last API tweaks... commit 2b2e9c40b195261b09ac52ebdb93eef25c79de90 Author: Daniel Drake <dsd@gentoo.org> Date: Fri May 16 22:37:56 2008 +0100 Fix endianness with descriptor handling Alan Stern pointed out that usbfs gives host-endian data, but sysfs gives bus-endian. commit 1298c51f516a7bf04ca9add1b7db14417cdc66f3 Author: Daniel Drake <dsd@gentoo.org> Date: Mon May 12 18:46:37 2008 +0100 Backend documentation for porting efforts Hopefully comprehensive enough for people to get started. commit ade26afc42c34ceb1c45afcadd2ea5e8240eaca4 Author: Daniel Drake <dsd@gentoo.org> Date: Mon May 12 15:43:30 2008 +0100 Linux: fix caching of guessed configuration Reported and tested by Xiaofan Chen commit e25d590a9198995b4f0b6afeb41ecae318715e7e Author: Rob Walker <rob@tenfoot.org.uk> Date: Sun May 11 21:14:18 2008 +0100 Linux: fix bulk transfer early completion We were forgetting about the remaining urbs when a non-final urb completed early.

Each libusb_device now has a reference count, defaulting to 1 on instantiation. The reference count of 1 refers to the fact that it is present in the list in this scenario. Opening a device adds a pointer to the libusb_device structure in the handle, so that also adds a reference. Closing the device removes that reference. The function to free the device list can optionally unref all the devices inside. In future we will make the libusb_device instances all "global" so that if the app calls get_device_list twice it actually gets the same libusb_device structure references back. This way we can start to track disconnects, and we can investigate adding a unique "session ID" to each libusb_device, an identifier guaranteed to be unique to that device until reboot. commit 77cea822788e024c848c7f554915f771a2dc1e0f Author: Daniel Drake <dsd@gentoo.org> Date: Thu Mar 6 17:05:04 2008 +0000 Remove ctrl debug code This was unintentionally committed commit b873521a6f575628d535f89278bb67888004d0ca Author: Daniel Drake <dsd@gentoo.org> Date: Tue Feb 26 22:11:34 2008 +0000 Notifications for changes to the fd set Applications can now be notified when they should start and stop polling new file descriptors. commit ca66e16a370c828d08a5bc3f9f203db145c81a4c Author: Daniel Drake <dsd@gentoo.org> Date: Fri Feb 1 12:20:20 2008 +0000 Fix header installation path commit e583100a4086c411093eef5c450880b965df6b1b Author: Daniel Drake <dsd@gentoo.org> Date: Wed Jan 30 13:24:54 2008 +0000 TODO update commit 637a8d7ff8a11a23588925d9d3003a609bda8075 Author: Daniel Drake <dsd@gentoo.org> Date: Wed Jan 30 13:19:10 2008 +0000 Remove timers and signalfd Instead of timers, add a mechanism for informing the parent app when the next timeout is due to happen, so that it can call us at that time.

Instead, using "libusb_" should be safer. commit e9364d72151ae1de9cce4175f330fe1529f02511 Author: Daniel Drake <dsd@gentoo.org> Date: Fri Jan 4 00:40:49 2008 +0000 Rename to libusb-1.0 I've taken over the libusb project, and what was previously known as fpusb will eventually be released as libusb-1.0. commit f4ed0b6a3e0a20555fdfc9e9b8be7e8a2c8ae192 Author: Daniel Drake <dsd@gentoo.org> Date: Sun Dec 30 22:09:50 2007 +0000 Compiler flags update Also fix some warnings commit d3d671efe27491baf1d2ceadbfeeb4e7428d6f9a Author: Daniel Drake <dsd@gentoo.org> Date: Sun Dec 30 22:05:17 2007 +0000 Fix signalfd structure size on x86 ptr is a 64-bit value commit dfac6756faad76071a92945e3e3a16b8a841a7ea Author: Daniel Drake <dsd@gentoo.org> Date: Wed Dec 12 23:32:54 2007 +0000 Don't pass ctrl_msg/bulk_msg structures through async paths These are easiest to construct on the stack, but in the async case it is likely that the submitting function returns (hence stack is destroyed) before URB completion. commit a8d2881eb7c273892acf2ff6e1f3f552631d1d11 Author: Daniel Drake <dsd@gentoo.org> Date: Mon Dec 3 23:29:22 2007 +0000 Add functionality to access device descriptors commit b5a7a411087b37a6bf56b4688a9e3290daaed153 Author: Daniel Drake <dsd@gentoo.org> Date: Mon Dec 3 22:27:21 2007 +0000 Rename fpusb_device_handle functions to devh Prevents confusion with functions that work on fpusb_dev structures. commit eacf4505a473df0f521d1b69d5b45448f0709e2d Author: Daniel Drake <dsd@gentoo.org> Date: Sun Dec 2 23:16:57 2007 +0000 Add API to access poll fd Almost forgot... :) commit 852bba4754ec57679c823f33e8feba6e4a564cbe Author: Daniel Drake <dsd@gentoo.org> Date: Wed Nov 28 13:48:45 2007 +0000 Initial commit Basic library structure which supports enumerating detected USB devices |
