ExternalStream defines protocol common to Streams which have a file-descriptor and |
799 |
represent some file or communicationChannel of the underlying OperatingSystem. |
|
800 |
ExternalStream is abstract; concrete classes are FileStream, PipeStream etc. |
|
| 77 | 801 |
|
| 159 | 802 |
ExternalStreams can be in two modes: text- (the default) and binary-mode. |
| 68 | 803 |
In text-mode, the elements read/written are characters; |
804 |
while in binary-mode the basic elements are bytes which read/write as SmallIntegers |
|
805 |
in the range 0..255. |
|
| 22 | 806 |
|
| 68 | 807 |
Also, the stream can be either in buffered or unbuffered mode. In buffered mode, |
808 |
data is not written until either a cr is written (in text mode) or a synchronizeOutput |
|
809 |
is sent (in both modes). |
|
| 22 | 810 |
|
| 77 | 811 |
The underlying OperatingSystem streams may either be closed explicitely (sending a close) |
| 68 | 812 |
or just forgotten - in this case, the garbage collector will eventually collect the |
| 77 | 813 |
object AND a close will be performed automatically (but you will NOT know when this |
814 |
happens - so it is recommended, that you close your files when no longer needed). |
|
| 159 | 815 |
Closing is also suggested, since if smalltalk is finished (be it by purpose, or due to |
| 77 | 816 |
some crash) the data will not be in the file, if unclosed. |
817 |
All streams understand the close message, so it never hurts to use it (it is defined as |
|
818 |
a noop in one of the superclasses). |
|
| 22 | 819 |
|
| 68 | 820 |
Most of the methods found here redefine inherited methods for better performance, |
821 |
since I/O from/to files should be fast. |
|
| 22 | 822 |
|
| 68 | 823 |
Recovering a snapshot: |
| 1295 | 824 |
not all streams can be restored to the state they had before - see the implementation of |
825 |
reOpen in subclasses for more information. |
|
826 |
For streams sitting on some communication channel (i.e. Pipes and Sockets) you should |
|
827 |
reestablish the stream upon image restart (make someone dependent on ObjectMemory). |
|
828 |
FileStreams are reopened and positioned to their offset they had at snapshot time. |
|
829 |
This may fail, if the file was removed or renamed - or lead to confusion |
|
830 |
if the contents changed in the meantime. |
|
831 |
Therefore, it is a good idea to reopen files and check for these things at restart time. |

Additional notes: |
|
864 |
This class is implemented using the underlying stdio-c library package, which |
|
865 |
has both advantages and disadvantages: since it is portable (posix defined), porting |
|
866 |
ST/X to non-Unix machines is simplified. The disadvantage is that the stdio library |
|
867 |
has big problems handling unbounded Streams, since the EOF handling in stdio is |
|
868 |
not prepared for data to arrive after EOF has been reached - time will show, if we need |
|
869 |
a complete rewrite for UnboundedStream ... |
|
| 325 | 870 |
|
| 188 | 871 |
Also, depending on the system, the stdio library behaves infriendly when signals |
872 |
occur while reading (for example, timer interrupts) - on real unixes (i.e. BSD) the signal |
|
873 |
is handled transparently - on SYS5.3 (i.e. non unixes :-) the read operation returns |
|
| 1295 | 874 |
an error and errno is set to EINTR. |
875 |
Thats what the ugly code around all getc-calls is for ... |
|
876 |
Since things get more and more ugly - we will rewrite ExternalStream |
|
877 |
completely, to NOT use any stdio stuff (and do its buffering itself). |
|
| 325 | 878 |
|
879 |
Notice that typical stdio's use a single errno global variable to return an error code, |
|
880 |
this was bad design in the stdio lib (right from the very beginning), since its much |
|
881 |
harder to deal with this in the presence of lightweight processes, where errno gets |
|
882 |
overwritten by an I/O operation done in another thread. (stdio should have been written |
|
883 |
to return errno as a negative number ...). |
|
884 |
To deal with this, the scheduler treats errno like a per-thread private variable, |
|
885 |
and saves/restores the errno setting when switching to another thread. |
|
886 |
(Notice that some thread packages do this also, but ST/X's thread implementation |
|
887 |
does not depend on those, but instead uses a portable private package). |
|
888 |
||
| 216 | 889 |
Finally, if an stdio-stream is open for both reading and writing, we have to call |
890 |
fseek whenever we are about to read after write and vice versa. |
|
891 |
Two macros (__READING__ and __WRITING__) have been defined to be used before every |
|
892 |
fread/fgetc and fwrite/putc respectively. |

|
2311 |
- for example, to control proprietrary I/O devices. |
|

||
2313 |
Since the type of the argument depends on the ioctl being |
|
2314 |
performed, different arg types are allowed here. |
|
2315 |
If the argument is nil, an ioctl without argument is performed. |
|
2316 |
If the argument is an integral number, its directly passed; |
|
2317 |
if its a kind of ByteArray (ByteArray, String or Structure), |
|
2318 |
or external data (ExternalBytes or ExternalAddress), |
|
2319 |
a pointer to the data is passed. |
|
2320 |
This allows performing most ioctls |
|

- however, it might be tricky to setup the buffer. |

Be careful in what you pass - ST/X cannot validate its correctness." |
