ExternalStream defines protocol common to Streams which have a file-descriptor and |
| 68 | 1347 |
represent some file or communicationChannel of the underlying OperatingSystem. |
1348 |
ExternalStream is abstract; concrete classes are FileStream, PipeStream etc. |
|
| 77 | 1349 |
|
| 159 | 1350 |
ExternalStreams can be in two modes: text- (the default) and binary-mode. |

In text-mode, the elements read/written are characters; |

while in binary-mode the basic elements are bytes which read/write as SmallIntegers |
| 68 | 1353 |
in the range 0..255. |
| 22 | 1354 |
|
| 68 | 1355 |
Also, the stream can be either in buffered or unbuffered mode. In buffered mode, |
1356 |
data is not written until either a cr is written (in text mode) or a synchronizeOutput |
|
1357 |
is sent (in both modes). |
|
| 22 | 1358 |
|
| 77 | 1359 |
The underlying OperatingSystem streams may either be closed explicitely (sending a close) |
| 68 | 1360 |
or just forgotten - in this case, the garbage collector will eventually collect the |

object AND a close will be performed automatically (but you will NOT know when this |
| 77 | 1362 |
happens - so it is recommended, that you close your files when no longer needed). |
| 159 | 1363 |
Closing is also suggested, since if smalltalk is finished (be it by purpose, or due to |

All streams understand the close message, so it never hurts to use it (it is defined as |
| 77 | 1366 |
a noop in one of the superclasses). |
| 22 | 1367 |
|
| 68 | 1368 |
Most of the methods found here redefine inherited methods for better performance, |
1369 |
since I/O from/to files should be fast. |
|
| 22 | 1370 |
|
| 68 | 1371 |
Recovering a snapshot: |
| 1295 | 1372 |
not all streams can be restored to the state they had before - see the implementation of |
1373 |
reOpen in subclasses for more information. |
|
1374 |
For streams sitting on some communication channel (i.e. Pipes and Sockets) you should |
|
1375 |
reestablish the stream upon image restart (make someone dependent on ObjectMemory). |
|
1376 |
FileStreams are reopened and positioned to their offset they had at snapshot time. |
|
1377 |
This may fail, if the file was removed or renamed - or lead to confusion |
|
1378 |
if the contents changed in the meantime. |
|
1379 |
Therefore, it is a good idea to reopen files and check for these things at restart time. |

Additional notes: |
|
1416 |
This class is implemented using the underlying stdio-c library package, which |
|
1417 |
has both advantages and disadvantages: since it is portable (posix defined), porting |
|
1418 |
ST/X to non-Unix machines is simplified. The disadvantage is that the stdio library |
|
1419 |
has big problems handling unbounded Streams, since the EOF handling in stdio is |
|
1420 |
not prepared for data to arrive after EOF has been reached - time will show, if we need |
|
1421 |
a complete rewrite for UnboundedStream ... |
|
| 325 | 1422 |
|
| 188 | 1423 |
Also, depending on the system, the stdio library behaves infriendly when signals |
1424 |
occur while reading (for example, timer interrupts) - on real unixes (i.e. BSD) the signal |
|
1425 |
is handled transparently - on SYS5.3 (i.e. non unixes :-) the read operation returns |

1426 |
an error and errno is set to EINTR. |
| 1295 | 1427 |
Thats what the ugly code around all getc-calls is for ... |
1428 |
Since things get more and more ugly - we will rewrite ExternalStream |
|
1429 |
completely, to NOT use any stdio stuff (and do its buffering itself). |
|
| 325 | 1430 |
|
1431 |
Notice that typical stdio's use a single errno global variable to return an error code, |
|
| 16508 | 1432 |
this was bad design in the stdio lib (right from the very beginning), since it's much |
| 325 | 1433 |
harder to deal with this in the presence of lightweight processes, where errno gets |
1434 |
overwritten by an I/O operation done in another thread. (stdio should have been written |
|
1435 |
to return errno as a negative number ...). |
|
1436 |
To deal with this, the scheduler treats errno like a per-thread private variable, |
|
1437 |
and saves/restores the errno setting when switching to another thread. |
|
1438 |
(Notice that some thread packages do this also, but ST/X's thread implementation |
|
1439 |
does not depend on those, but instead uses a portable private package). |
|
1440 |
||
| 216 | 1441 |
Finally, if an stdio-stream is open for both reading and writing, we have to call |
1442 |
fseek whenever we are about to read after write and vice versa. |
|
1443 |
Two macros (__READING__ and __WRITING__) have been defined to be used before every |
|
1444 |
fread/fgetc and fwrite/putc respectively. |

next:count into:anObject startingAt:start |
3351 |
"read the next count bytes into an object and return the number of |
|
3352 |
bytes read or the number of bytes read, if EOF is encountered before. |
|
3353 |
If the receiver is some socket/pipe-like stream, an exception |
|
3354 |
is raised if the connection is broken. |
|
3355 |
||
3356 |
Warning: if used with a pipe/socket, this blocks until the requested number |
|
3357 |
of bytes have been read. See #nextAvailableBytes:into:startingAt: |
|
3358 |
to only read whats there. |
|
3359 |
||
3360 |
Notice, that in contrast to other methods, |
|
3361 |
this does NOT return nil on EOF, but the actual count. |
|
3362 |
Thus allowing read of partial blocks. |
|
3363 |
||
3364 |
The object must have non-pointer indexed instvars |
|
3365 |
(i.e. it must be a ByteArray, String, Float- or DoubleArray), |
|
3366 |
or an externalBytes object (with known size). |
|
3367 |
If anObject is a string or byteArray and reused, this provides the |
|
3368 |
fastest possible physical I/O (since no new objects are allocated). |
|
3369 |
||
3370 |
Use with care - non object oriented I/O. |
|
3371 |
Warning: in general, you cannot use this method to pass data from other |
|
3372 |
architectures (unless you prepared the buffer with care), |
|
3373 |
since it does not care for byte order or float representation." |
