dispatch: only do __import__(debugger) when a debugger is requested
When having ui.debugger=somedebugger in one's ~/.hgrc, this then
somedebugger would be imported for every hg command. With this patch,
this import only happens if the --debugger parameter is passed.
hg: use "os.path.join()" to join path components which may be empty (
issue4203)
Changset
2d0ab571b822 rewriting "hg.copystore()" with vfs uses
'dstbase + "/lock"' instead of "os.path.join()", because target files
given from "store.copyfiles()" already uses "/" as path separator
But in the repository using revlog format 0, "dstbase" becomes empty
("data" directory is located under ".hg" directly), and 'dstbase +
"/lock"' is treated as "/lock": in almost all cases, write access to
"/lock" causes "permission denied".
This patch uses "os.path.join()" to join path components which may be
empty in "hg.copystore()".
revset: document the regular expression support for tag(name)
This has been supported since
20f55613fb2a, in 2.3.
help: let 'hg help debug' show the list of secret debug commands
The names of the debug commands are not easy to remember and they are not easy
to find.
tests: add run-tests --changed option for running tests changed in revisions
Convenient when polishing patches and changing details of how they change test
output.
This will probably break in weird ways for revsets with special quoting ... but
it is good enough for run-tests.
Usage example:
yes | ./run-tests.py -li --changed qparent
repo: rephrase the "missing requirement" error message
Unknown requirements will now be reported as:
abort: repository requires features unknown to this Mercurial: largefiles!
(see http://mercurial.selenic.com/wiki/MissingRequirement for more information)
Some features of this phrasing:
* avoid double ':' in abort message
* make it more clear who requires and knows what
* don't quote the requirement names - it is not something the user entered or
need the exact spelling of ... and it is "identifiers" that are unambiguous
anyway
* remove double hint by removing "(upgrade Mercurial)" comment
* don't mention upgrading Mercurial without mentioning enabling the feature -
instead, just refer to wiki page for both
* don't just talk about "details", talk about "more information"
revpair: drop useless conditional
The `if not revs:` case is tested at the beginning of the function.
