2003-06-04 Jeffrey Stedfast <fejj@ximian.com> * camel-uid-cache.c (camel_uid_cache_new): Create the directory with mode 0777 and the cache file itself with mode 0666. Let the user's umask filter the permissions. Instead of saving the fd on the Cache object, instead save the filename. Use camel_read() instead of expecting read() to just always work without getting an EINTR/etc. (maybe_write_uid): Don't do anything if cache->fd == -1, this means an error has occured in a previous callback. Replace the 2 calls to write() with camel_write() and check their return values. If either of them fails, set cache->fd to -1 (GHashTable doesn't give us a way to abort foreach'ing thru the table). (camel_uid_cache_save): Save to a temp file instead of overwriting the original. Do proper error checking, etc. Also added some smarts about whether to try and overwrite the old cache even if we haven't successfully saved all the uids in the cache. (camel_uid_cache_destroy): Free the cache->filename, no longer need to close (cache->fd). svn path=/trunk/; revision=21416
