transaction: clear callback instances after usage Prevents double usage and helps reduce reference cycles, which were observed to occur in `hg convert` and other scenarios where there are multiple transactions per process.

lock: clear postrelease hooks list after usage Post release hooks should only be called once. Setting the list to None after usage will prevent accidental usage after they are used. In addition, it is easy for reference cycles to sneak into hook functions. Clearing the hooks after usage helps prevent these cycles.

ui: drop template aliases by HGPLAIN Otherwise, scripting output could be suffered from user aliases.

templater: load and expand aliases by template engine (API) (issue4842) Now template aliases are fully supported in log and formatter templates. As I said before, aliases are not expanded in map files. This avoids possible corruption of our stock styles and web templates. This behavior is undocumented since no map file nor [templates] section are documented at all. Later on, we might want to add [aliases] section to map files if it appears to be useful.

templater: inline compiletemplate() function into engine This allows the template engine to modify parsed tree.

templater: factor out function that creates templater from string template This function will host loading of template aliases. It is not defined at templater, but at formatter, since formatter is the module handling ui stuff in front of templater.

templater: separate function to create templater from map file (API) New frommapfile() function will make it clear when template aliases will be loaded. They should be applied to command arguments and templates in hgrc, but not to map files. Otherwise, our stock styles and web templates (i.e map-file templates) could be modified unintentionally. Future patches will add "aliases" argument to __init__(), but not to frommapfile().

templater: extract function that loads template map file Prepares for API change. See the next patch for details. 'map' variable is renamed to avoid shadowing map() function.

templater: demote "base" directory of map file to local variable It isn't referenced from other places.

notify: do not load style file if template is specified (BC) This patch makes sure that either "tmpl" or "mapfile" is exclusively set, which is the same behavior as common log-like templates and formatter outputs. See the previous patch for why.

bugzilla: do not load style file if template is specified (BC) This prepares for the API change to support template aliases. I'm going to extract a factory function of templater that reads a map file: # original templater(mapfile, ..., cache, ...) # new templater.frommapfile(mapfile, ...) # read mapfile to build cache/map templater(..., cache, ...) # use specified cache (= map elements) This will make it clear to isolate stock styles (i.e. map files) from user aliases. Template aliases should be applied to command arguments and templates in hgrc, but not to map files. Otherwise, our stock styles and web templates could be modified unintentionally. This patch makes sure that either "tmpl" or "mapfile" is exclusively set. It's theoretically a behavior change, since you could put new keywords in template by defining them in a map file before: # mapfile foo = "{rev}" # hgrc [bugzilla] style = mapfile template = {foo} But the old behavior would be a bug because bugzilla.template is documented as "overrides style if specified". Also, common log-like templates and formatter doesn't allow using mapfile-keywords in a separate template. So I decided to make a BC. Since there was no test for the bugzilla extension, this adds new test that covers style/template output.

hook: report untrusted hooks as failure (issue5110) (BC) Before this patch, there was no way for a repository owner to ensure that validation hooks would be run by people with write access. If someone had write access but did not trust the user owning the repository, the config and its hook would simply be ignored. After this patch, hooks from untrusted configs are taken into account but never actually run. Instead they are reported as failures right away. This will ensure validation performed by a hook is not ignored. As a side effect writer can be forced to trust a repository hgrc by adding a 'pretxnopen.trust=true' hook to the file. This was discussed during the 3.8 sprint with Matt Mackall, Augie Fackler and Kevin Bullock.

hook: split config reading further We want an easy way to fetch the hook config with and without honoring "trusted" so that we can compare the values. So we extract the part retrieving raw hook data from the config to be able to call it twice in the next patch.

hook: small refactor to store hooks as dict instead of list We are about to take untrusted hooks into account (to report them as failures) so we need to rearrange the code a bit to allow config overwriting each other in a later patch.

mail: retain hostname for sslutil.wrapsocket (issue5203) SMTPS + STARTTLS need to provide serverhostname, and we can't store it in sslkwargs because that breaks something involving the https protocol.

tests: make test-trusted use print_function There was some confusing output format at some places in test-trusted.py.out, the new print function ends with a newline by default whereas the old print statement uses a space generally. So the output in test-trusted.py.out is changed because of some confusing output format which was produced by print statement

crecord: cleanup the remains of commit confirmation The confirmation screen is now only used for the 'review' option we simplify the code and rename the function.

crecord: drop the extra confirmation screen The commit confirmation is not very useful -- it gives no way to view what you have selected, so you're blindly choosing whether to proceed or not, and it adds a lot of unnecessary friction to committing. In addition, we now have a working 'review' choice for those who really want to review the final change. Ryan McElroy initially submitted a config option to make this optional, but we never saw a V2. However as the freeze is near and curses have never been officially out of the door, I think it is worth skipping the config and trying getting it right for this release.

update: resurrect bare update from null parent to tip-most branch head The situation is tricky if repository has no "default" branch, because "null" revision belongs to non-existent "default" branch. Before e1dd0de26557, bare update from null would bring us to the tip-most non-closed branch head. e1dd0de26557 removed the special handling of missing "default" branch since we wanted to stick to the uncommitted branch in that case. But, if the parent is "null" revision, and if the missing branch is "default", it shouldn't be an uncommitted branch. In this case, bare update should bring us to the tip-most head as before. This should fix the test breakage introduced by e1dd0de26557.

tests: run import-checker with tests .t files

import-checker: parse python code from .t files

import-checker: track filenames for SyntaxErrors

import-checker: track SyntaxErrors We don't really need to report SyntaxErrors, since in theory docchecker or a test will catch them, but they happen, and we can't just have the code crash, so for now, we're reporting them.

import-checker: refactor source reading This will allow .t files to generate multiple sources. It will also allow .py doctests to generate additional sources.
