export: add %m to file format string (first line of the commit message)
$ hg commit -m "Initial commit"
$ hg export -o %m.patch tip #It creates Initial_commit.patch file.
setdiscovery: return anyincoming=False when remote's only head is nullid
This fixes (
issue2907) a crash when using 'hg incoming --bundle' with an empty
remote repo and a non-empty local repo.
This also fixes an unreported bug that 'hg summary --remote' erroneously
reports incoming changes when the remote repo is empty and the local is not.
Also, add a test to make sure
issue2907 stays fixed
i18n: use UTF-8 string to lower filename for case collision check
Some character sets, cp932 (known as Shift-JIS for Japanese) for
example, use 0x41('A') - 0x5A('Z') and 0x61('a') - 0x7A('z') as second
or later character.
In such character set, case collision checking recognizes different
files as CASEFOLDED same file, if filenames are treated as byte
sequence.
win32mbcs extension is not appropriate to handle this problem, because
this problem can occur on other than Windows platform only if
problematic character set is used.
Callers of util.checkcase() use known ASCII filenames as last
component of path, and string.lower() is not applied to directory part
of path. So, util.checkcase() is kept intact, even though it applies
string.lower() to filenames.
check-code: disallow use of hasattr()
The hasattr() builtin from Python < 3.2 [1] has slightly surprising
behavior: it catches all exceptions, even KeyboardInterrupt. This
causes it to have several surprising side effects, such as hiding
warnings that occur during attribute load and causing mysterious
failure modes when ^Cing an application. In later versions of Python
2.x [0], exception classes which do not inherit from Exception (such
as SystemExit and KeyboardInterrupt) are not caught, but other types
of exceptions may still silently cause returning False instead of
getting a reasonable exception.

demandimport: use getattr instead of hasattr
We don't use util.safehasattr() here to avoid adding new dependencies
for demandimport. This change may expose previously-silenced
deprecation warnings to appear, as hasattr silently hides warnings
that occur during module import when using demandimport.
