Python 2.6 introduced the "except type as instance" syntax, replacing
the "except type, instance" syntax that came before. Python 3 dropped
support for the latter syntax. Since we no longer support Python 2.4 or
2.5, we have no need to continue supporting the "except type, instance".
This patch mass rewrites the exception syntax to be Python 2.6+ and
Python 3 compatible.
This patch was produced by running `2to3 -f except -w -n .`.
Extension authors (notably at companies using hg) have been
cargo-culting the `testedwith = 'internal'` bit from hg's own
extensions, which then defeats our "file bugs over here" logic in
dispatch. Let's be more aggressive about trying to give extension
authors a hint about what testedwith should say.
"working directory" is the standard term, we should use it consistently.
But I didn't touch the hint, "run 'hg update' to get a working copy", because
"get a working directory" sounds a bit odd.
0e5f75a52c9d introduced a way to share bookmarks. When a repository share that
shares bookmarks was created, a .hg/bookmarks.shared file was created to mark
the repository share as one that shares its bookmarks.
We have plans to introduce other levels of sharing, including a "full share"
mode. Rather than creating a new ".shared" file for each new thing that we may
want to share It seems better to create a single "shared" file that will list
what is shared for a given shared repository. This should make it much easier
to get a list of everything that is shared by a given shared repository.
The shared file contains a list of shared "items" (such as bookmarks). Each
shared "item" is added as a new line in the file. For now the only possible
entry in the file is "bookmarks".
Up until now we compared the "path" and "sharedpath" repository properties to
check if a repository is shared. This was relying an implementation detail of
shared repositories. In order to make it possible to change the way shared
repositories are implemented, we encapsulate this check into its own localrepo
method, called shared.
This new method returns None if the repository is shared, and something else
(for now a string describing the short of share) otherwise.
The reason why I did not call this method "isshared" and made it return a
boolean is that I plan to introduce a new type of shared repository soon.
# NOTES:
This is the first patch in a series whose purpose is to add support for
creating "full repository shares", which are repositories that share everything
with the repository source except their current revision, branch and bookmark.
This series is RFC because I am not very sure of some of the solutions I took.
Comments are welcome!
The stored path contains platform specific separators, so splitting on '/.hg'
returned the string unmodified on Windows. The source was then looked for in
$source/.hg/.hg, which obviously fails. This caused cascading errors in
test-share.t relating to the recent bookmark support.
This patch adds the -B/--bookmarks option to the share command added by the
share extension. All it does for now is create a marker, 'bookmarks.shared',
that will be used by future code to implement the sharing functionality.
This does not cause any behavioral change unless a 'bookmarks.shared' marker
file exists. A future change will add UI to create this file when a repository
is shared.
When running the unshare command, if there's other code that tries to use
the repo after the command is finished, it'll end up with a ui object for
repo.unfiltered(). This change fixes an erroneous call to repo.__init__()
that could be on the repoview proxy class--now it's always done on the
unfiltered repo.
A repo should not get the configuration from an other repo, so create it with
the global configuration in repo.baseui.
This is done too when recreating a repo. The repo configuration is reread
anyway. And now deleted repo configuration does not persist.
Trying as much as possible to consistently:
- use a present tense predicate followed by a direct object
- verb referring directly to the functionality provided
(ie. not "add command that does this" but simple "do that")
- keep simple and to the point, leaving details for the long help
(width is tight, possibly even more so for translations)
Thanks to timeless, Martin Geisler, Rafael Villar Burke, Dan Villiom
Podlaski Christiansen and others for the helpful suggestions.
