ExternalStream defines protocol common to Streams which have a file-descriptor and |
| 68 | 1391 |
represent some file or communicationChannel of the underlying OperatingSystem. |
1392 |
ExternalStream is abstract; concrete classes are FileStream, PipeStream etc. |
|
| 77 | 1393 |
|
| 159 | 1394 |
ExternalStreams can be in two modes: text- (the default) and binary-mode. |

while in binary-mode the basic elements are bytes which read/write as SmallIntegers |
| 68 | 1397 |
in the range 0..255. |
| 22 | 1398 |
|
| 68 | 1399 |
Also, the stream can be either in buffered or unbuffered mode. In buffered mode, |
1400 |
data is not written until either a cr is written (in text mode) or a synchronizeOutput |
|
1401 |
is sent (in both modes). |
|

The underlying OperatingSystem streams may either be closed explicitely (sending a close) |

All streams understand the close message, so it never hurts to use it (it is defined as |
| 77 | 1410 |
a noop in one of the superclasses). |
| 22 | 1411 |
|
| 68 | 1412 |
Most of the methods found here redefine inherited methods for better performance, |
1413 |
since I/O from/to files should be fast. |

Recovering a snapshot: |
| 1295 | 1416 |
not all streams can be restored to the state they had before - see the implementation of |
1417 |
reOpen in subclasses for more information. |
|
1418 |
For streams sitting on some communication channel (i.e. Pipes and Sockets) you should |
|
1419 |
reestablish the stream upon image restart (make someone dependent on ObjectMemory). |
|
1420 |
FileStreams are reopened and positioned to their offset they had at snapshot time. |
|
1421 |
This may fail, if the file was removed or renamed - or lead to confusion |
|
1422 |
if the contents changed in the meantime. |
|
1423 |
Therefore, it is a good idea to reopen files and check for these things at restart time. |

Additional notes: |
|
1461 |
This class is implemented using the underlying stdio-c library package, which |
|
1462 |
has both advantages and disadvantages: since it is portable (posix defined), porting |
|
1463 |
ST/X to non-Unix machines is simplified. The disadvantage is that the stdio library |
|
1464 |
has big problems handling unbounded Streams, since the EOF handling in stdio is |
|
1465 |
not prepared for data to arrive after EOF has been reached - time will show, if we need |
|
1466 |
a complete rewrite for UnboundedStream ... |
|
| 325 | 1467 |
|
| 188 | 1468 |
Also, depending on the system, the stdio library behaves infriendly when signals |
1469 |
occur while reading (for example, timer interrupts) - on real unixes (i.e. BSD) the signal |
|
1470 |
is handled transparently - on SYS5.3 (i.e. non unixes :-) the read operation returns |

an error and errno is set to EINTR. |
| 1295 | 1472 |
Thats what the ugly code around all getc-calls is for ... |
1473 |
Since things get more and more ugly - we will rewrite ExternalStream |
|
1474 |
completely, to NOT use any stdio stuff (and do its buffering itself). |
|
| 325 | 1475 |
|
1476 |
Notice that typical stdio's use a single errno global variable to return an error code, |
|
1477 |
this was bad design in the stdio lib (right from the very beginning), since its much |
|
1478 |
harder to deal with this in the presence of lightweight processes, where errno gets |
|
1479 |
overwritten by an I/O operation done in another thread. (stdio should have been written |
|
1480 |
to return errno as a negative number ...). |
|
1481 |
To deal with this, the scheduler treats errno like a per-thread private variable, |
|
1482 |
and saves/restores the errno setting when switching to another thread. |
|
1483 |
(Notice that some thread packages do this also, but ST/X's thread implementation |
|
1484 |
does not depend on those, but instead uses a portable private package). |
|
1485 |
||
| 216 | 1486 |
Finally, if an stdio-stream is open for both reading and writing, we have to call |
1487 |
fseek whenever we are about to read after write and vice versa. |
|
1488 |
Two macros (__READING__ and __WRITING__) have been defined to be used before every |
|
1489 |
fread/fgetc and fwrite/putc respectively. |

This is not used by ST/X, but provided for special situations |
| 2920 | 2913 |
- for example, to control proprietrary I/O devices. |
2914 |
||
2915 |
Since the type of the argument depends on the ioctl being |
|
2916 |
performed, different arg types are allowed here. |
|
2917 |
If the argument is nil, an ioctl without argument is performed. |

If the argument is an integral number, its directly passed; |

if its a kind of ByteArray (ByteArray, String or Structure), |

or external data (ExternalBytes or ExternalAddress), |

This allows performing most ioctls |
| 2920 | 2923 |
- however, it might be tricky to setup the buffer. |

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