histedit: add description about basic histedit function to command help
Before this patch, there is no explicit description that histedit
edits changesets between specified ancestor and the parent of the
working directory: users may notice it by error message "REV is not an
ancestor of working directory".
This patch adds description about basic histedit function to command
help of it.
This patch uses term "ancestor" instead of "parent", because it seems
to be more suitable, and almost all (error) messages already use it.
httpclient: import
0d1b0a8bc549 to fix bug involving late-arriving RST after a response
After a day of hunting this defect, I'm now unable to reproduce the
bug without this patch applied. Regardless, this should fix the
problem I was observing with wireshark. Hopefully this fixes any
flakiness in the buildbot from http2.
progress: stop getting stuck in a nested topic during a long inner step
Convert, for example, has loops like this:
for revision in source_repo:
progress(revisions)
for file in revision:
progresss(file)
Prior to this change, we would start showing the file-level progress
when we encountered a big revision, and then we'd get stuck in showing
file-progress instead of revision progress, often producing many many
instantly-completing progress bars rather than the actually-helpful
top-level revisions bar.
