If the name already existed, then there's no need to Put it, otherwise it gets set inside the Do call, which also means there's no need to Put it.
…back `statGuess` guesses We make sure the fallback statGuess name is the base file name, not the absolute path. Otherwise in scenarios where statGuess does not manage to find a Name method on the underlying object, it will return an absolute path, which will generate bad message errors, due to slashes not being allowed in file names.
When a styxfile.Directory is passed as the result of a Tcreate call and the underlying object does not have a Stat method, statGuess does not manage to detect any underlying fs.FileInfo methods, (e.g.: Name, Mode, ...) which means that for opened directories, the results of Tstat are always an incorrectly guessed fallback value

Closing this PR in favour of #34, which introduces the same fix, but from a different branch. Github won't let me change the source branch |

Reverts incorrect changes introduced in #30, which broke Rwalk (for which there were failing tests that went unnoticed).

Putcall in qidpool: if it already exists, there's no need to Put it, otherwise it gets handled inside theDoblock, so still no need for aPut.In the #30 PR, @seh-msft says:
If there's a new file being created, that means the file doesn't exist yet, which means the Twalk should fail. In the event of an unsuccessful Twalk, no new Qid should be created. I've added a new test that verifies this behaviour is true.
Considering the above, this is still true: Twalk fails, no Qid is created, then Tcreate occurs, and the Qid and file get created.
In conclusion, the current behaviour is correct, so this PR reverts back to that -- there was no need for a fix. I am not sure what issues the original submitter was facing, but I am guessing that they were not coming from styx.
