We restrict : to 1. make it easer to convert bookmarks to git branches,
2. use : later for a syntax to push a local bookmark to a remote bookmark
of a different name. \0, \n, \r are fobbidden they are used to separate
bookmarks in the bookmark file.
This change breaks backward compatbility as ':' was an allowed character in
previous versions.
Previously, when rolling back a transaction, some users could be confused
between the level to which the store is rolled back, and the new parents
of the working directory.
$ hg rollback
rolling back to revision 4 (undo commit)
With this change:
$ hg rollback
repository tip rolled back to tip revision 4 (undo commit)
working directory now based on revision 2 and 1
So now the user can realize that the store has been rolled back to an older
tip, but also that the working directory may not on the tip (here we are
rolling back the merge of the heads 2 and 1)
Invalid requests could give an unhandled ErrorResponse.
Now this ErrorResponse is handled like other ErrorResponses so the client gets
an error message which also is logged on the server.
Other exceptions than StandardExceptions were left to the default error handler
which was muted when running in daemon mode.
Now all Exceptions are handled and logged to the log file.
The archive list generator was holding a reference to each
temporary ui copy passed by rawentries(), so the memory
usage for index generation growed proportionally to the
ui object size and the amount of repositories. By returning a
list instead, the temporary reference is dropped immediately.
Consider a repository with a single subrepository. The changesets in
the main repository reference the subrepository changesets like this:
m0 -> s0
m1 -> s1
m2 -> s2
Starting from a state (m1, s0), doing 'hg update m2' in the main
repository will yield a conflict: the subrepo is at revision s0 but
the target revision says it should be at revision s2.
Before this change, Mercurial would do (m1, s0) -> (m2, s2) and thus
ignore the conflict between the working copy and the target revision.
With this change, the user is prompted to resolve the conflict by
choosing which revision he wants. This is consistent with 'hg merge',
which also prompts the user when it detects conflicts in the merged
.hgsubstate files.
The prompt looks like this:
$ hg update tip
subrepository sources for my-subrepo differ
use (l)ocal source (fc627a69481f) or (r)emote source (12a213df6fa9)?
The default behaviour is to commit subrepositories with uncommitted changes. In
my experience this is usually undesirable:
- Changes to dependencies are often debugging leftovers
- Real changes should generally be applied on the source project directly,
tested then committed. This is not always possible, subversion subrepos may
include only a small part of the source project, without the tests.
Setting ui.commitsubrepos=no will now abort commits containing such modified
subrepositories like:
$ hg --config ui.commitsubrepos=no ci -m msg
abort: uncommitted changes in subrepo sub
I ruled out the hook solution because it does not easily take --include/exclude
options in account. Also, my main concern is whether this flag could cause
problems with extensions. If there are legitimate reasons for callers to
override this behaviour (I could not find any), they might either override at ui
level, or we could add an argument to localrepo.commit() later.
v2:
- Renamed ui.commitsubs to ui.commitsubrepos
- Mention the configuration entry in hg help subrepos
In testing of my recent addition of a debugignore command, some of my MacHg
users uncovered the exceptional case that if there is no ignore patterns of any
kind then a traceback occurred. Catch and fix this case.
