News file for Stow.
|
||||
|
||||
* Changes in version 2.1.3
|
||||
|
||||
** ./configure now checks for Perl modules required by the test suite.
|
||||
|
||||
* Changes in version 2.1.2
|
||||
|
||||
Many thanks to Stefano Lattarini for help with numerous autoconf and
|
||||
automake issues which are addressed in this release.
|
||||
|
||||
** Significantly improve the handling of --with-pmdir.
|
||||
|
||||
*** Calculation of the default value for --with-pmdir is now done safely in Perl.
|
||||
|
||||
Previously non-POSIX-compliant shells could cause issues.
|
||||
|
||||
*** The output of ./configure and make are now much more helpful.
|
||||
|
||||
*** The Makefile will now check whether pmdir is in Perl's built-in @INC.
|
||||
|
||||
If not, it will insert a
|
||||
|
||||
use lib "...";
|
||||
|
||||
line into the generated stow script to ensure that it can always
|
||||
locate the Perl modules without needing to manually set PERL5LIB.
|
||||
|
||||
*** Updated INSTALL and HOWTO-RELEASE accordingly.
|
||||
|
||||
** ./configure now aborts if Perl isn't found.
|
||||
|
||||
** Ensured the ChangeLog is up-to-date when making a new distribution.
|
||||
|
||||
** Fixed bug with `make clean' removing files which the user may not be able to rebuild.
|
||||
|
||||
* Changes in version 2.1.1
|
||||
|
||||
** Fixed bug where ./configure --with-pmdir=X was ineffectual.
|
||||
|
||||
** Calculated the correct default value for pmdir based on the local Perl installation.
|
||||
|
||||
** Fixed some automake issues (thanks to Stefano Lattarini for spotting these!)
|
||||
|
||||
** Improved various bits of documentation.
|
||||
|
||||
* Changes in version 2.1.0
|
||||
|
||||
** Major refactoring of code into separate Stow and Stow::Util Perl modules.
|
||||
|
||||
** Added support for ignore list files.
|
||||
|
||||
** Added support for CPAN-style installation and distribution via Module::Build.
|
||||
|
||||
** Introduced `make test' target and significantly tightened up test suite.
|
||||
|
||||
** Very large number of code and documentation fixes (over 80 commits since version 2.0.1).
|
||||
|
||||
** The '--conflicts' option has been removed.
|
||||
|
||||
Stow will always show conflicts if they are found during the scanning
|
||||
phase.

** Improved debugging output.
|
||||
|
||||
** Converted man page to POD format.
|
||||
|
||||
** Include PDF, and both split- and single-page HTML versions of manual in the distribution.
|
||||
|
||||
** Fixed code style consistency issues.
|
||||
|
||||
** Running configure from outside the source tree now works.
|
||||
|
||||
** `make distcheck' now works.
|

* Changes in version 2.0.1

** Defer operations until all potential conflicts have been assessed.

||||
|
||||
We do this by traversing the installation image(s) and recording the
|
||||
actions that need to be performed. Redundant actions are factored out,
|
||||
e.g., we don't want to create a link that we will later remove in order to
|
||||
create a directory. Benefits of this approach

1. Get to see _all_ the conflicts that are blocking an installation:
|

you don't have to deal with them one at a time.
|
||||
2. No operations are be performed if _any_ conflicts are detected:
|
||||
a failed stow will not leave you with a partially installed
|
||||
package.
|
||||
3. Minimises the set of operations that need to be performed.
|
||||
4. Operations are executed as a batch which is much faster
|
||||
This can be an advantage when upgrading packages on a live system
|
||||
where you want to minimise the amount of time when the package is
|
||||
unavailable.

For example, man pages that are shared by a number of CPAN packages.

Using multiple stow directories and .stowrc files can also simplify

things. In our setup we use the standard /usr/local/stow directory for

packages to be installed in /usr/local. Since we install a large number
|

of extra Perl packages (currently about 300) we use an additional stow
|
||||
directory: /usr/local/stow/perl-5.8.8-extras. Both stow directories
|
||||
contain a '.stow' file so that they collaborate appropriately. I then use

When I stow packages from there, they automatically override any man pages

That is, we only search for bad symlinks in the directories explicitly

subdirs. Digging down into other directories can be very time consuming

if you have a really big tree (like with a couple of Oracle installations

lying around). In general the old behaviour is only necessary when you

have really stuffed up your installation by deleting a directory that has

already been stowed. Doing that on a live system is somewhat crazy and

hopefully rare. We provide an option '-p|--compat' to enable the old

behaviour for those needing to patch up mistakes.

more easily check for equivalent functionality. The initial code base had

to be refactored substantially to allow for testing. The test suite is

not exhaustive, but it should provide enough to check for regressions.
