From 187659d7d30e183a4ef8f54703408f45af3c1253 Mon Sep 17 00:00:00 2001 From: Nikias Bassen Date: Fri, 31 Jul 2009 03:30:21 +0200 Subject: [PATCH 01/14] Try locking the lockfile multiple times until we get a lock. When the MobileMusicPlayer app is running and the sync is started, it will be closed down. The lockfile is locked by the music player and it takes 1-2 seconds for MobileMusicPlayer to terminate. So we'll wait a maximum of 10 seconds to get the file lock. --- src/itdbprep/libitdbprep.c | 10 +++++++++- 1 files changed, 9 insertions(+), 1 deletions(-) diff --git a/src/itdbprep/libitdbprep.c b/src/itdbprep/libitdbprep.c index 8325a9a..4166dde 100644 --- a/src/itdbprep/libitdbprep.c +++ b/src/itdbprep/libitdbprep.c @@ -1402,7 +1402,15 @@ int itdbprep_start_sync(const char *uuid, itdbprep_t *prepdata) } /* lock /com.apple.itunes.lock_sync */ - afcerror = afc_file_lock(pdata_loc->afc, pdata_loc->lockfile, AFC_LOCK_EX); + int retries = 0; + do { + afcerror = afc_file_lock(pdata_loc->afc, pdata_loc->lockfile, AFC_LOCK_EX); + if (afcerror == AFC_E_SUCCESS) { + break; + } + sleep(1); + } while (retries++ < 10); + if (afcerror != AFC_E_SUCCESS) { fprintf(stderr, "%s: ERROR: could not lock lockfile (AFC error code %d)\n", __func__, afcerror); afc_file_close(pdata_loc->afc, pdata_loc->lockfile); -- 1.6.4.4
