doc/README: simplify instructions

doc: use our own rst2man.py script (issue1746) The rst2man tool has not yet been part of an official Docutils release, and it is not present in most distributions. This poses a problem for people who want to install Mercurial from source, or who want to create a Mercurial package for such a distribution -- how to specify the build-dependencies? By including the rst2man.py script with Mercurial people only need a normal Docutils installation in order to install Mercurial.

util, minirst: do not crash with COLUMNS=0

manifestdict: remove unnecessary dictionary copy No need to copy the dict, dict.__init__() will do that for us. It was responsible for a non-negligeable waste of time during a qpush of an -mm queue on the kernel repo.

manifest.add(): cleanup worklist construction and iteration

manifest: simplify cache handling, use a unique cache

manifest.add(): simplify with iterators and generator expressions

color: do all setup in uisetup Now that extensions are loaded in phases, we are guaranteed to always find mq in uisetup with extensions.find and we know that the mq commands are not yet copied into commands.table.

extensions: pass ui arguement to extsetup if accepted

extensions: load and configure extensions in well-defined phases Extensions are now loaded with a call-graph like this: dispatch._dispatch extensions.loadall extensions.load # add foo module to extensions._extensions extensions.load # add bar module to extensions._extensions foo.uisetup(ui) bar.uisetup(ui) foo.extsetup() bar.extsetup() commands.table.update(foo.cmdtable) commands.table.update(bar.cmdtable) hg.repository foo.reposetup(ui, repo) bar.reposetup(ui, repo) The uisetup calls could easily be moved out to dispatch._dispatch, but have been kept in extensions.loadall since at least TortoiseHg calls extensions.loadall and expects it to call uisetup. The extensions.load function called uisetup. It now has an unused ui argument which has been kept for backwards compatibility.

highlight: move code from module top-level into extsetup

run-tests: standardize on --foo instead of -f/--foo We write -f/--foo in Mercurial help texts (docstrings), but I think it looks strange in error messages.

run-tests: use parser.error for cmdline option errors

doc/README: rst2man is now in Docutils proper

doc/Makefile: detect the right name for rst2man and rst2html docutils uses the .py extension on the commands, and so do their installer. Distribution packages might strip the .py, but the official name should work too.

Merge with crew-stable

test-keyword: update output to match 5d49fdef6fd0

hgweb: show diff header line in raw diffs

doc/Makefile: Don't show Makefile comments in output The comments makes sense when editing Makefile, but not when watching its output where it looks too much like error messages.

doc/Makefile: detect rst2man errors Make couldn't detect rst2man errors when it wasn't the last command, so empty man page files would be installed.

test-hooks: Don't hide the value of HG_PENDING Hiding the value of HG_PENDING made it less obvious what was going on in case of test failure

ui: fix NameError in ui.progress due to unit/units typo

util: quicker fspath, do not lower names when the length is different

test-casefolding: fix wrong case on hfs on linux on linux hfs keeps the old case of the file stored force it by renameing to another name and back

hghave: check for case insensitive filesystem in current dir check was done on TEMP

run-tests: expand --tmpdir and create it if needed

patch: remove the unused, broken reverse() function

patch: readgitpatch: remove unused variable 'src'

use 'x in dict' instead of 'dict.has_key(x)' "in" is faster, and has_key will be removed in py3k

churn: use genexps now that we dropped 2.3 compatibility
