| Summary | open does not reset the internal file pointer of a previously closed file port |
|---|---|
| Description |
open on a file port, that was previously closed, does not reset the file pointer to the beginning of the file. Therefore the data can be read only once. This applies to read as to copy . |
| Example code |
>> write %test "abcdefg"
>> read %test
== #{61626364656667}
>> f: open %test
>> read f
== #{61626364656667}
>> close f
>> read f
== #{}
>> open f
>> read f
== #{}

Interesting that consecutive call to 'close seems to cure the situation. We are dealing with probably internally two different behaviours to 'read? One is direct read of the file, while the other one, where we 'open the file port first, calls port 'read actor? |

The bug is fixed. Both of the #{} strings now contain the file contents.
NOTE: The READ f is allowed even when port is not open, because f is a valid port spec and we allow a direct read on such ports. Please be sure to test this change really well. Thanks. |
