wix: include the help for pager Similar (I assume) to 65d2538ac993.

manifest: check 'if x is None' instead of 'if not x' The old code here would end up executing __len__ on a tree manifest to determine if 'not _data' was true or not. This was very expensive on large repos. Since this function just cares about memoization, we can just check 'if _data is None' instead and save a bunch of time.

pager: add support to --patch, --list and --stat options of hg shelve

color: drop the 'colorui' class Now that all logics formally bared by 'colorui' have been moved to the main ui class, that class is empty and can be dropped. As a nice side effect we can get rid of the baroque Initialization associated to it. There was much rejoicing.

color: move 'write-err' logic to the core ui class This is similar to what we needed for 'write', we move the logic from the extension to the core class. Beside the dispatch to 'win32print', we just apply label to the argument.

ui: extract low level part of 'write_err' in its own method Same as for 'write' and '_write' we needs it available for some of the color logic.

ui: extract buffer write from protect and timed 'write_err' output That subcall to 'self.write' is never doing actual write but only store things in buffers. So we do not need to protect it for exception not to time its execution. This will make it easier to extract a '_write_err' function as we did for 'write'.

color: move 'write' logic to the core ui class One more step, the support for writing color is not directly in core. No behavior change for the default case ('_colormode' = None). Here are the details of what we have to change to the core method: * apply to 'self.label' to input in the buffered case * dispatch to 'win32print' when applicable * apply to 'self.label' to input when applicable

ui: extract the low level part of 'write' in a dedicated function We are about to add some extra logic related to color. That logic will need to access the low level layer of ui doing the actual write to a stream. (eg: 'win32print'). We extract this logic into a private method for this purpose.

color: add multiple messages input support to 'win32print' All other function doing writes support any number of input message. For simplicity, we make 'win32print' able to do the same.

color: clarify name of an argument of 'win32print' In the current code, the function called to write happens to the 'orig' version of the method calling 'win32print' (obtained with a 'super' call). However, the variable could have a better name. That will be useful when we'll stop having inheritance in play.

color: move the 'colorlabel' call to the core 'ui' class This bring us closer to supporting color in core natively. Core already have a 'label' method that was a no-op. We update its to call the new 'colorlabel' function. Behavior is unchanged when colormode = None.

color: move the 'colorlabel' function in the core module The extract code is relocated in core.

color: extract the label code into its own function We extract the logic into a function. This will allow us to move the logic into the core 'color' module and later call it directly from core.

color: inline the 'showlabel' method This function is quite simple and only have one call site… located a handful of line under the definition. We inline the function for the sake of simplicity. One of the motivation to do that now is that it reduce the amount of new method we will have to add to the core 'ui' class for color support.

color: move '_colormode' to the core 'ui' class Having all 'ui' objects aware of 'color' allows us to update the core code to handle color. The mode will stay 'None' in the default case so that will not introduce any changes.

hgweb: explictly pass basectx in webutil.diffs There's only one case where `basectx` parameter is None (over two usages), so it's probably not worth handling the special case as it makes code-reading harder. Along the way, use ctx.p1() instead of checking for ctx.parents() being empty which should not occur.

serve: mark --stdio and --cmdserver as "(ADVANCED)" flags This will hide them from the default --help output.

help: hide command line options marked as "advanced" Previously, we have keywords like "(DEPRECATED)" and "(EXPERIMENTAL)" to hide command line options in non-verbose help output. However, sometimes an option is neither deprecated nor experimental. It's well-tested and working, but just not designed to average users. This patch adds a keyword "(ADVANCED)" to fit in such use cases. Thanks rom1dep for the suggestion of the word "advanced".

pager: do not try to run an empty pager command If pagercmd is explicitly set to '', the pager process would exit silently and the output would be lost. We'd better disable the pager in such case.

graphlog: restore pager lost at 1cec1d863008

gitweb: add "more" and "less" navigation links in filelog template

context: also return ancestor's line range in blockancestors

context: add a followfirst flag to blockancestors

py3: use pycompat.fsencode() to convert __file__ to bytes __file__ returns unicodes on Python 3. This patch uses pycompat.fsencode() to convert them to bytes.

wireproto: remove unused code Removed an unused line introduced by f3807a135e43.

color: set initial default value for 'colormode' to None This should not introduce any behavior changes when using the color extension. In practive, the colormode will be setup at early at run time to the proper value (from config and environment). We do this change as this gets us closer of a state were we can have all the mechanisms associated to color in core with the feature disabled by default.

color: minor reversal of two conditional clause for clarity Another minor cleanup while reading the code. The two branches of the conditional have similar complexity so we go for the order that give us the simplest condition (we drop the negation).
