rebase: fix 'rebase onto %d starting from %s' - show root instead of list repr
The debug statement is already in a 'for root in roots' so it was probably the
intention to show root instead of roots. Do that.
log: describe graph symbols in the help
I wondered what 'x' meant and didn't find it described anywhere.
tests: backout
a82de9dc4f77, debugstacktrace is now stable, drop workaround
util: debugstacktrace, flush before and after writing
Close another stream (default stdout, which often is buffered) before writing
to the primary stream (default stderr, which often is unbuffered). The primary
stream is also flushed after writing (in case it is buffered).
This fixes non-deterministic output order, especially on windows.
run-tests.py: work when --with-hg is set to system hg
Previously we'd always assume that --with-hg is a script in a user directory,
and would write out a 'python' symlink to the same location. That didn't work
if --with-hg was set to a system installation of hg, e.g. /usr/bin/hg.
Introduce a TMPBINDIR directory which is used to write out the python symlink.
