Combining translated string fragments into bigger strings is bad
practice because it removes context from the fragments. The translator
sees the fragments in isolation and might not jump back to the source
to see how a string like "%d files %s" is actually used.
When cloning with the -r option or # url format from a tag the destination
repo most likely won't have the tag. We can save the lookup result to get to
the correct parent anyway. Similar to issue1306, but for tags.
In many places hg.parseurl is called with a url and "opts.get('rev')",
suggesting the second, optional argument can be None. Because opts['rev']
usually defaults to [] this never happens in practice.
However, extensions don't necessarily behave the same, but do copy this
pattern.
Also, include wider hg.parseurl tests, beyond a demonstration of the problem.
If the user created the clone target directory before running
the clone command, only cleanup the .hg/ repository when errors
occur. Leave the empty target directory in place.
With this change, "hg clone" looks like this:
% hg clone http://example.com/repo/big big
requesting all changes
adding changesets
adding manifests
adding file changes
added XXX changesets with XXX changes to XXX files
updating working directory
XXX files updated, XXX files merged, XXX files removed, XXX files unresolved
So the user sees
% hg clone http://example.com/repo/big big
requesting all changes
adding changesets
adding manifests
adding file changes
added XXX changesets with XXX changes to XXX files
updating working directory
while Mercurial is writing to disk to populate the working directory
With this change, "hg clone" looks like this:
% hg clone big big-work
updating working directory
XXX files updated, XXX files merged, XXX files removed, XXX files unresolved
A new function (extensions.extensions) allows the code that is
interested in those attributes to handle them directly.
This allows some cleanups of extensions.py. Notably, we can
remove the extensions.commandtable hack.
It also makes it easier to add standard extension attributes,
like a "hgwebsetup" function or a "helptable" dict that augments
the data in help.py, etc.
This allows you to do:
hg clone http://server/repo#stable
which is equivalent to:
hg clone -r stable http://server/repo
Future incoming, outgoing, and push commands will default to using
this id because it's recorded in the default path.
Other commands that accept URLs (push, pull, bundle, incoming, and
outgoing) also accept this syntax.
The ui object we received in this function may belong to another repo,
which could be confusing from the hook point of view. Trying to use
the ui object from the newly created repo should avoid this confusion.
since creating a repo raises an exception if the repo already
exists, there's no need to try to create one.
add some test for repo creation when the destination exists
islocal tells if a repo or url is local.
defaultdest returns default path for clone if explicit path not given.
clone can now take repo or url as source
existing clone code uses pull to get changes from remote repo. is very
slow, uses lots of memory and cpu.
new clone code has server write file data straight to client, client
writes file data straight to disk. memory and cpu used are very low,
clone is much faster over lan.
new client can still clone with pull, can still clone from older servers.
new server can still serve older clients.
str.find return -1 when the substring is not found, -1 evaluate
to True and is a valid index, which can lead to bugs.
Using alternatives when possible makes the code clearer and less
prone to bugs. (and __contains__ is faster in microbenchmarks)
Rearranged the clone command a good bit to make sure it validates that
the source does exist and that the destination doesn't before doing anything.
Before I moved the source repo check it would create the destination
repository before it verified the source existed.
Moved the responsibility for creating the destination repo root directory
entirly into the localrepo class so that local to local cloning doesn't break.
This also simplifies the code a bit since it's no longer being done in both
clone and init.
Changed the names of the 'repo' and 'other' variables to 'dest_repo' and
'src_repo' to maintain my sanity.
Passes 82/83 tests. The only failure is the version number test, which I
suspect is supposed to fail since it comes from a generated file.
- create new statichttprepo class
- pull remote bits out of localrepo
- pull remote bits out of util.opener
- switch hg.repository to use statichttprepo
TAH found a bug where push would push things the remote already had,
raising an assertion. This turned out to be because the changeset
protocol was not recording a common subset node in one case.
Also discovered was that the protocol was queueing multiple copies of
a node for pull. Fixed by changing fetch to a hash.
Add some more debugging output.
- rename mode to branch_merge
- use explicit update mode
- use negative mtime for updates that set mtime
- expand some cryptic variable names
- elaborate merge dirstate comments
- remove redundant manifest lookup for non-merge case
- remove impossible merge case
- fix up test cases
- use new changed list to track what files actually got new revlog entries
at commit/rawcommit time
- when updating a file during a merge, don't mark it as completely unchanged
- handle file not being in parent 1 in status
Since switching to the multihead approach, we've been creating
excessive file-level merges where files are marked as merged with
their ancestors.
This explicitly checks at commit time whether the two parent versions
are linearly related, and if so, reduces the file check-in to a
non-merge. Then the file is compared against the remaining parent,
and, if equal, skips check-in of that file (as it's not changed).
Since we're not checking in all files that were different between
versions, we no longer need to mark so many files for merge. This
removes most of the 'm' state marking as well.
Finally, it is possible to do a tree-level merge with no file-level
changes. This will happen if one user changes file A and another
changes file B. Thus, if we have have two parents, we allow commit to
proceed even if there are no file-level changes.
Right now, mercurial doesn't take daylight saving time into account
because it uses time.timezone inconditionally, instead of resorting to
time.altzone if daylight saving time is on.
named branching is when you identify a head by a tag on an earlier revision.
This patch adds repo.branchlookup for searching through the tree to
find branch tags for heads.
hg update -b tag is added to checkout based on branch tags
hg heads -b is added to print the tag associated with each head
