Question about "cvs update"

Question about "cvs update"

[Hui Zhu]

Hi guys,

"cvs update -d" will make the src directory include a lot of other
softwares like binutils, sid and so on.

I want keep the directory just have the file of GDB.  I tried "cvs
update -dP".  But it still tried to checkout the files of other
softwares.

Could someone tell me how to update the all src directory and do not
co the files of other softwares.

Thanks,
Hui

Yes, one should not use -d for the sourceware tree.

To handle the cases of new directories I do completely new checkouts nightly.
As I use CVS only for check-ins (and GIT for real work with the tree) it has
no problems.

`cvs checkout' into the existing tree should update it, possibly with the
right directories tracking.  But I was unable to set it up for sourceware.


Regards,
Jan

Thanks Jan, I think I can use the git.  :)

I cheat, like this:

cd gdb-checkout
ln -s . src
cvs co gdb

That will check out gdb using the same tag and cvsroot that was
previously used.

  I do something roughly(*) like:

ls -1d */CVS | cut -d/ -f1 | xargs cvs up -dP

... followed by a plain old "cvs up" to get the top-level files.  This can
easily be put into a shell alias or function definition in one of your shell
startup scripts.

(*) - Actually, I'm lazy.  I really do "ls -l" and take advantage of the
windows terminal's rectangular-block-copy-paste mode to select all the
directory names and paste them straight into the xargs invocation, but that's
not important right now.

Irks.  I just do "cvs co" which knows to update instead of
checkout if you already have a tree, but wrapped in a tiny script
that I carry around to all my trees:

 $ cat /home/pedro/gdb/baseline/cvsup.sh 
 #!/bin/bash

 cvs -t -d :ext:palves@sourceware.org:/cvs/src co gdb

That's it!

To avoid hacks, I just have my sources in a directory
called literally "src".  E.g., I follow this layout:

 /home/pedro/gdb/baseline/src
 /home/pedro/gdb/baseline/build
 /home/pedro/gdb/baseline/cvsup.sh 

and 

 /home/pedro/gdb/foo-project/src
 /home/pedro/gdb/foo-project/build
 /home/pedro/gdb/foo-project/cvsup.sh 

etc.

When I want to update a tree, I just e.g.,

 $ cd /home/pedro/gdb/baseline
 $ ./cvsup.sh

When I want to create a new fresh checkout, I do:

 $ mkdir /home/pedro/gdb/fresh-project
 $ cd /home/pedro/gdb/fresh-project
 $ cp /home/pedro/gdb/baseline/cvsup.sh /home/pedro/gdb/fresh-project
 $ ./cvsup.sh

(or copy an existing tree)

I prefer copying the script file because sometimes I want to checkout
a specific date / tag / branch.  E.g.,

 $ cat /home/pedro/gdb/7_0/cvsup.sh
 #!/bin/bash
 cvs -t -z9 -d :ext:palves@sourceware.org:/cvs/src co -r gdb_7_0-branch gdb
