* Avoid holding semaphore while making mmap callbacks.David Smith2009-06-091-52/+130
| | | | | | | | | * runtime/task_finder.c (__stp_call_mmap_callbacks_for_task): Grabs the 'mmap_sem' sempaphore. Caches vma information, releases the semaphore, then makes mmap callbacks. (__stp_utrace_task_finder_target_quiesce): Calls __stp_call_mmap_callbacks_for_task() to make mmap callbacks on initial attach to a task.
* Avoid 1 case of holding a semaphore while mmap callbacks are being made.David Smith2009-06-091-57/+75
| | | | | | | | | | * runtime/task_finder.c (__stp_call_mmap_callbacks_with_addr): Renamed from __stp_call_mmap_callbacks_with_vma(). Also added some code from __stp_utrace_task_finder_target_syscall_exit() that locks the 'mmap_sem' semaphore. This avoids holding the semaphore while the mmap callbacks are made. (__stp_utrace_task_finder_target_syscall_exit): Just calls __stp_call_mmap_callbacks_with_addr() in the mmap case.
* Make sure all DEBUG_TRANS output uses printk.David Smith2009-06-032-13/+21
| | | | | | | | * runtime/transport/control.c (_stp_ctl_write_cmd): Calls dbug_trans2 instead of _dbug (so that printk is used instead of the transport itself). (_stp_ctl_write_dbug): Ditto. * runtime/debug.h (dbug_trans2): New macro.
* Fixed STP_TRANSPORT_VERSION 1 behavior.David Smith2009-06-036-23/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * runtime/transport/control.c (_stp_ctl_write_dbug): Added support for more messages. * runtime/transport/relay_v2.c (_stp_transport_data_fs_start): New function. (_stp_transport_data_fs_stop): Ditto. (_stp_transport_data_fs_close): Moved some functionality into _stp_transport_data_fs_stop() and calls _stp_transport_data_fs_stop() also. (_stp_transport_data_fs_init): Moved some functionality into _stp_transport_data_fs_start() and calls _stp_transport_data_fs_start() also. * runtime/transport/relayfs.c (_stp_transport_data_fs_start): New function. (_stp_transport_data_fs_stop): Ditto. (_stp_transport_data_fs_close): Moved some functionality into _stp_transport_data_fs_stop() and calls _stp_transport_data_fs_stop() also. (_stp_transport_data_fs_init): Moved some functionality into _stp_transport_data_fs_start() and calls _stp_transport_data_fs_start() also. * runtime/transport/ring_buffer.c (_stp_transport_data_fs_start): New empty function. (_stp_transport_data_fs_stop): Ditto. * runtime/transport/transport.h: Added _stp_transport_data_fs_start() and _stp_transport_data_fs_stop() prototypes. * runtime/transport/transport.c (_stp_cleanup_and_exit): Calls _stp_transport_data_fs_stop(). (_stp_transport_close): Calls _stp_transport_fs_close() earlier. (_stp_transport_init): Calls _stp_transport_data_fs_start().
* Cleanup and better original transport support.David Smith2009-05-263-4/+12
| | | | | | | | | | * runtime/print.h: Moved _stp_reserve_bytes() prototype here. * runtime/vsprintf.c (_stp_vsnprintf): Includes print.h to get _stp_reserve_bytes() prototype. * runtime/transport/transport.c (_stp_remove_root_dir): Better cleanup for STP_TRANSPORT_VERSION == 1. (_stp_transport_fs_close): Ditto.
* Added error checking and other updates.David Smith2009-05-227-488/+44
| | | | | | | | | | | | | | | | | | * runtime/vsprintf.c: Added transport.h inclusion for STP_BUFFER_SIZE definition. * runtime/transport/debugfs.c (_stp_register_ctl_channel_fs): Added error checking. * runtime/transport/transport.c (_stp_get_root_dir): Ditto. (_stp_transport_fs_init): Added original transport support and error checking. * runtime/transport/relay_v2.c (__stp_relay_create_buf_file_callback): Added error checking. (_stp_transport_data_fs_init): Ditto. * runtime/transport/ring_buffer.c (_stp_transport_data_fs_init): Ditto. * runtime/transport/utt.c: Removed unused file. * runtime/transport/utt.h: Ditto.

| | | | | | | | | | | | We have the saved_conversion_error field, but I wasn't using it. Now @cast errors are saved in that field, so they're only seen if the optimizer doesn't remove the @cast.
| * PR10054: Unify the translate_components errorsJosh Stone2009-05-081-39/+12
| | | | | | | | | | | | | | Since translate_components is the one that knows the details of its failures, it makes more sense to let it throw its own errors, instead of relying on each caller to do it. The function now always either returns successfully or throws an error.
| * Refactor anonymous lookups in translate_componentsJosh Stone2009-05-082-114/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous code recursed the entirety of translate_components, and it seemed to be restarting the components list every time, so it would only work if the anonymous portion was the first component. Even then, examining the code output by semok/thirtythree revealed that it wasn't fully translating the locations when multiple anonymous pieces were involved. Instead, it now recurses in a separate function, find_struct_member, which does just enough to find the member die and return. It also builds a vector of the locations passed through, so translate_components can output code for the full chain of anonymity. The generated code for semok/thirtythree's $page->mapping now appears to match the offsets from my manual inspection of struct page. I also added a test for $page->first_page->mapping, which works now but would segfault the old code.

| * Simplify buildok/context_test.stpJosh Stone2009-05-081-20/+1
| | | | | | | | | | | | | | | | | | | | The test was using optional probes on uptime_read_proc, which doesn't exist anymore on 2.6.30. The problem is that when those optional probes are skipped, the test doesn't really do anything. For a buildok test of the context functions, the actual probe point doesn't matter, so I've changed it to just a begin probe that calls all of the functions.

| |\ | | | | | | | | | | | | | | | This merge splits some of the built-in tapsets into their own files, so we can better maintain clean interfaces. Still TODO are the dwarf- dependent tapsets though, because that's a much bigger mess to untangle.
