progress: restore testedwith to the stub Without this, hg always claims progress is at fault for problems, which is completely crazy.

hgweb: make refresh interval configurable hgwebdir refreshes the set of known repositories periodically. This is necessary because refreshing on every request could add significant request latency. More than once I've found myself wanting to tweak this interval at Mozilla. I've also wanted the ability to always refresh (often when writing tests for our replication setup). This patch makes the refresh interval configurable. Negative values indicate to always refresh. The default is left unchanged.

filemerge: add 'union' merge to internal merge tool 'union merge' is a merge strategy which adds both left and right hand side of a conflict region. Git implements this merge strategy which is very practical to have for merging e.g. the Changelog file.

filemerge: split internal merge into api entry point and internal helper This is a step toward adding 'union merge' to the internal merge tool. 'union merge' is a merge strategy which adds both left and right hand side of a conflict region. Git implements this merge strategy which is very practical to have for merging to e.g. the Changelog file.

simplemerge: add 'mode' kwarg which - when 'union' - suppresses markers This is a step toward adding 'union merge' to the internal merge tool. 'union merge' is a merge strategy which adds both left and right hand side of a conflict region. Git implements this merge strategy which is very practical to have for merging to e.g. the Changelog file. Note: the identifiers with underscores in this commit are all using existing variable names and/or keyword arguments.

hghave: remove quiet option The --quiet flag appears to be unused. Kill it.

hghave: move feature checking into hghave.py Upcoming patches will kill hghave (the script - not hghave.py) and will move to a model where requirements checking is performed as a function call. Start diminishing the utility of hghave by moving some code to hghave.py.

tests: move '#require bzr' into .t files The bzr tests are the only .t tests calling hghave (aside from the tests testing hghave itself). This pattern is a one-off and prevents desired refactors to how requirements checking is integrated into tests. Use the convention used everywhere else.
