Big cleanup of camel-stream-*, got rid of 3 classes, improved the interfaces,
and fixed at least one problem (end of stream never happening in certain cases). Things that can fail now have a way of saying they failed too. So much for taking ANZAC day off to get drunk! 2000-04-26 NotZed <NotZed@HelixCode.com> * camel-seekable-substream.c (stream_seek): Changed to have absolute seek semantics, not relative to the bounds. * camel-seekable-stream.c (reset): When we reset, seek to the start of the bound, if there is one. (stream_tell): Make tell virtual. * camel-stream-filter.c (do_available): Removed. * camel-stream-buffer.c: Remove leading _'s from static functions. (stream_read): Renamed from read(). Fancy that conflicting! (my boo!) Others too. * providers/pop3/camel-pop3-folder.c (get_message_by_number): Changed to stream_mem interface. * providers/mbox/camel-mbox-folder.c (_get_message_by_uid): Fixed for streamfs interface changes, and implement a failure case. (_append_message): Changed for fs stream interface change. * camel-multipart.c (print_part): Iterate rahter than callback. I hate glists's interface (hence, move this to write_to_stream). (write_to_stream): Return an error (yuck, this is a royal PITA to do with the stream write interface). * camel-mime-message.c: Removed leading _ from static names. * camel-mime-part.h: construct_from_parser() now returns an error code. * camel-mime-part-utils.c (camel_mime_part_construct_content_from_parser): Changed to use a camel-data-wrapper instead of a camel-simple-data-wrapper (no change needed elsewhere?). (simple_data_wrapper_construct_from_parser): Fixes for stream-mem interface changes. * camel-simple-data-wrapper.[ch], camel-simple-data-wrapper-stream.[ch], camel-stream-data-wrapper.[ch], removed. Fixed including of these files. * camel-mime-part.c (camel_mime_part_set_text): Remove the use of the camel-simple-data-wrapper-stream, just use a mem stream. (write_to_stream): Renamed from my_* (construct_from_stream): Return an error on error. * camel-stream-mem.c (camel_stream_mem_new*): Remove mode parameter. * camel-stream-mem.h (enum CamelStreamMemMode): Removed. It wasn't used at all. * camel-data-wrapper.h: Add camel_data_wrapper_new() to create these. (write_to_stream, construct_from_stream): Return an error indicator for success. Fixed all methods to match (ICK). * Makefile.am (libcamel_la_SOURCES): Remove camel-simple-data-wrapper.c, camel-simple-data-wrapper-stream.c, camel-stream-data-wrapper.c. Obsoleted by code re-use! * camel-data-wrapper.c (construct_from_stream): Change the default implementation to just set the output stream == construction stream. Well, this lets me get rid of both simple-data-wrapper and stream-data-wrapper (unused anyway), and simple-data-wrapper-stream in one hit. CamelDataWrapper is now also a concrete class. (write_to_stream): Use camel_stream_write_to_stream() to calculate/return values (and save code). Include <errno.h> for obvious reasons. * camel-stream.c (eos): Provide a default implementation of .eos(). (camel_stream_write_to_stream): Make it return an error code on error. (camel_stream_printf): Changed to return the number of bytes written/error. (camel_stream_available): Removed. * camel-stream-fs.h (enum CamelStreamFsMode): Removed. Changed to use unix modes and so forth (wasn't used for anything but new file creation and didn't work well either). * camel-stream-fs.c: Removed leading _'s for names. And removed some virtual method 'documentation'. (destroy): Dont try and close a closed/error fd. Only report error if close returns -1. Moved all the code to finalise(), and killed this function. (init_with_fd): Properly setup the seek offset, if it is a valid and seekable file descriptor. (init_with_fd_and_bounds): Use off_t for bounds, set bounds on the seekable stream. (init_with_name): Return error codes. (init_with_name_and_bounds): Ditto. (camel_stream_fs_new_with_name): REturn NULL object if it failed. (camel_stream_fs_new_with_name_and_bounds): Return NULL object on failure. Changed with_name* api's to take unix open style args and flags. (read): The bounded stream bounds checking seemed off, simplified code a bit. (write): Implement bounds checking for writing, the comment was wrong, it could make sense to bound writing. Cleaned up a little. (available): Gone. (eos): Removed. Use CamelStream's implementation now. (close): Reset the fd to -1, provide a warning for bad usage. (seek): Cleaned up. Changed the behaviour a little, the returned offset is the absolute position in the file, even in bounded streams. (seek): Seek from end mirrors lseek() behaviour (reverse seeking). 2000-04-25 NotZed <NotZed@HelixCode.com> * camel-stream-fs.h (struct _CamelStreamFs): Moved bounds and eof indicator to other parent classes. * camel-stream.c (camel_stream_printf): New utility function. Obvious use. * camel-stream-mem.c: Removed leading _'s from static func's. (camel_stream_mem_new_with_byte_array): Fixed for api changes, set the owner for the byte array to us. : Removed A bunch of gtk doc stuff for static (implementation) functions. (available): Removed. (write): Fixed the write implementation so that seek() works on a seekable memory stream, as expected. Seeking past the end of the buffer has unix semantics (filling with 0). (available): Removed. (write): Implement seekable stream bounded stream. (read): Implement seekable stream bounded stream. (close): Dont free the stream_mem if we're not the owner. (seek): Allow to seek beyond the end of memory area, implement bounds checking. (seek): Set errno on bad policy. * camel-stream-mem.h (struct _CamelStreamMem): Changed position to off_t. (new_with_buffer): Changed len to be a size_t. (set_buffer, set_byte_array): New interface functions. (struct _CamelStreamMem): Removed position, it is stored in the superclass. * camel-stream.h: Removed some of the seemingly random whitespace. Removed the available method (its not impelemented/useful enough). * camel-seekable-substream.c (init_with_seekable_stream_and_bounds): Remove the data_available stuff, it hasn't been properly implemented/finished, and may never work (unfortunately *sigh). (reemit_parent_signal): Removed part of the above change. (set_bounds): Removed (moved to seekable-stream). : Fixed up some of the generally unreadable indenting (sorry, wrapping at 80 characters with camels_really_long_function_names() just_doesnt_work_very_well_does_it(). (available): Removed. (stream_seek): Fixup for object changes. Make sure we return -1 if the parent stream can't seek. * camel-seekable-stream.c (ccamel_seekable_stream_set_bounds): New function to bound any seekable stream. : Removed _'s. (camel_seekable_stream_class_init): Implement an init function, to setup the stream bounds to unbound. * camel-seekable-stream.h (CamelSeekableStreamClass): New virtual method set_bounds for seekable streams. (CAMEL_STREAM_UNBOUND): New define for no bound. * camel-seekable-substream.h (struct _CamelSeekableSubstream): Removed sup_bound and inf_bound, moved to CamelSeekableStream (and renamed, and changed to off_t's). (new_with_seekable_stream_and_bounds): Use off_t as the bounds. (CamelSeekableSubstreamClass): Uh, why was the intialiser virtual? Removed. * camel-seekable-stream.[ch] (CamelSeekableStreamClass): Changed seek to accept an off_t as the offset. (struct _CamelSeekableStream): Renamed cur_pos to position and changed it to an off_t type. (enum CamelStreamSeekPolicy): Set to match the SEEK_* constants from lseek(). (get_current_position): Renamed to tell(). * camel-stream-buffer.h: Commented out set_vbuf - never implemented. svn path=/trunk/; revision=2624
