- From: Arnold Robbins <arnold%gatech.csnet@CSNET-RELAY.ARPA>
-
- Over a few nights, I sat down and read Draft 6 of the P1003 draft
- standard. Overall, it is really good, and the committee has done a
- good job. Many of my comments are related to spelling, typographical,
- and grammar errors. These are not important relative to the comment,
- but should be cleaned up. The moderator should feel free to delete
- those comments from what gets posted, as long as they get passed on to
- the editor(s).
-
- [ Might as well post them. Besides, it's easier to pass things on
- if they're all in one place. -mod ]
-
- The rest of my comments are just comments; something is referred to in
- one place that was dropped elsewhere, or something left out, things of
- that nature. Some of this should (I hope) stimulate good discussion.
- Replies should probably go to the net, since I won't be here at Georgia
- Tech for much longer.
-
- I'll be posting several articles, to keep the size down, probably one
- per chapter of the draft. Here is the Introduction, and Chapters 1 and 2.
- Stuff quoted from the draft is indented, my comments are flush with the
- left margin. The moderator should feel free to edit as he sees fit.
-
- [ I've mostly just run fmt over stuff that wouldn't fit on 80 column
- screens and added comments like this. -mod ]

- COVER PAGE:
-
- Prepared by the P1003 working group of the Operation System Standards...
- ^^^^
-
- Should be "Operating System"
- ^^^
- FORWARD:
- [ That's FOREWORD, i.e., a word that goes in front, not a direction to go in.
- -mod ]
- CHAPTER 1:
- No comments.
-
- CHAPTER 2:
- Sect 2.2:
- ... Non-standard extenstions
- ^ (spelling error)
-
- Sect 2.3 General Terms:
-
- Address Space
- The range of memory locations, both code and data, that
- can be referenced by a process.
-
-
- Neither "code" nor "data" are defined anywhere. Is this one of those things
- everyone knows what they are?
- [ There's supposedly an IEEE dictionary of such things. -mod ]
-
- -----
- Process Lifetime
- ... When a process executes a _wait()_ primitive for an
- inactive process, ....
-
- Should clarify that the inactive process can only be waited on by certain
- processes (its ancestor(s)), not just any arbitrary process.
-
- -----
- Parent Process ID
-
- Should indicate that the parent process ID may change if the parent dies
- before the child.
-
- -----
- Real User ID and Real Group ID
- Each user is also a member of a group.
-
- Should say something like "Each user is also a member of at least one group."
- This helps with 4.2BSD systems.
-
-
- ... and real group ID. respectively, of the ...
- ^
-
- The period should be removed.
- [ Should be a comma, actually. -mod ]
-
- -----
- Pipe
-
- Should indicate that a pipe has the same behavior as a FIFO file for the
- _close()_ primitive as well.
-
-
- -----
- Directory
-
- Should have an additional statement to the effect that directories are not
- writable by normal user code; only system calls (_link()_, _mkdir()_, _rmdir()_,
- etc., give a full list) shall be used to modify directory contents.
-
- -----
- Root Directory and Current Working Directory
- ... A process's root directory need not be the root directory
- of the root file system.
-
- What is the "root file system"? This isn't defined.
- [ And we thought we'd rooted out all references to file systems. :-) -mod ]
-
- ===========================================
-
- Sect 2.4 Error Numbers:
-
- ENOENT No such file or directory
- This error occurs when a file name is specified **and the file
- should exist but doesn't**, or when a directory in a path name
- does not exist.
-
- The starred phrase just doesn't ring true. Maybe something like "but the file
- does not exist" would be better. Who's to say whether or not the file "should"
- exist?
-
- ===========================================
-
- Sect 2.6 Environment Description:
-
- It is recommended the follwoing variable names....
-
- Should be "It is recommended that the..."
- ^^^^
-
- ===========================================
-
- 2.7 C Language Definitions
-
- A character is any bit pattern able to fit into a single byte.
-
- "Byte" is left undefined here. Maybe it should be specified that it is
- at least 8 bits?
-
- ===========================================
-
- 2.8 Numerical Limits
-
- {SYYS_OPEN} Maximum number of files that can be open 16
- on the system at one tiime.
-
- This number seems awfully small to me.
- [ Historically accurate, though. -mod ]
-
- Volume-Number: Volume 4, Number 11
