rebase: pass in "user" instead of "ctx" to conclude[memory]node() This was the only remaining part of the context object that was needed. Differential Revision: https://phab.mercurial-scm.org/D2923

rebase: look up default date outside of conclude[memory]node() Differential Revision: https://phab.mercurial-scm.org/D2922

rebase: move config override out of conclude[memory]node() Differential Revision: https://phab.mercurial-scm.org/D2921

rebase: pass in entire "overrides" dict to conclude[memory]node() As with previous patches, this was done the same way in both functions, so let's make the caller do it instead. Differential Revision: https://phab.mercurial-scm.org/D2920

rebase: pass in "keepbranch" to conclude[memory]node() Both functions calculated the same "keepbranch" value from the "keepbranches" we passed in, so let's make the caller do it instead. Differential Revision: https://phab.mercurial-scm.org/D2919

rebase: inline _makextrafn() now that we have only one caller Also avoid even creating a function since we just end up calling it right away. Differential Revision: https://phab.mercurial-scm.org/D2918

rebase: pass in "extra" itself into conclude[memory]node() We were passing in a function instead for no clear reason (probably historical, but I haven't bothered looking). Differential Revision: https://phab.mercurial-scm.org/D2917

rebase: look up commit message to reuse outside of conclude[memory]node() This was done the same way in both functions, so let's let the single caller do it. Differential Revision: https://phab.mercurial-scm.org/D2916

rebase: pass in ctx, not rev, to conclude[memory]node() They both need it and there's no locking that might make the results different, so let's do it in one place. This also lets us move out more common code in the following patches. Differential Revision: https://phab.mercurial-scm.org/D2915

rebase: extract common _concludenode() _rebasenode() and _finishrebase() had a lot of code in common. This commit extracts some of that. This means we will also have a single caller of concludenode() and concludememorynode(), which gives us a place to put code that is common between those two functions (which is quite a bit). Differential Revision: https://phab.mercurial-scm.org/D2914

rebase: store rebase state after each commit Before this patch, we stored the rebase state early in the processing of a node, before we updated the rebase state to indicate that the node was processed. This meant that we could redo the working copy merge and run into conflicts. However, this only happened in the --collapse case if the rebase was interrupted while editing the final commit message; in the case earlier interruptions, we would instead detect the in-process revision by finding two dirstate parents. This patch moves the writing of the rebase state to after we have completed the revision completely, and, importantly, after we have updated the rebase state to mark it done. This means we'll realize that all nodes have been rebased in the case mentioned above of editing the final commit message of a --collapse. See change to test case. I also moved the writing outside of the large if/elif block in _rebasenode(). This shouldn't matter much, but seems cleaner. One observable effect is if rebase was interrupted just after ignoring an obsolete node ("not rebasing ####, already in destination"), we used to come up with the same decision after --continue too, but after this patch we'll instead say "already rebased ###". This seems more consistent, since that's what we would do with obsolete nodes that had been marked done earlier in the process (not only just before the interruption).

rebase: register status file generator only once when using single transaction rebase.storestatus() behaved differently depending on whether a transaction is passed to it. If a transaction is passed, it registers a "file generator" that runs when the transaction commits. If no transaction was passed, it writes the rebase state immediately. This imprecise timing of the writing makes it hard to reason about, so let's make it more explicit which behavior we're getting by checking if we have a transaction before calling it. For the single-transaction case, move the call to storestatus(tr) early and do it only once since it's only going to write the file (at most) once anyway. Differential Revision: https://phab.mercurial-scm.org/D2912

tests: add some more tests to test-rebase-collapse.t Some of these are currently broken. Differential Revision: https://phab.mercurial-scm.org/D2911

tests: use drawdag in test-rebase-collapse.t This makes the tests shorter (410 lines -> 240 lines), faster (17s -> 12s), and easier to read (the setup for each test case is just before the test, and we can refer to commits by name). Differential Revision: https://phab.mercurial-scm.org/D2910

rebase: remove unused default argument values from conclude[memory]node() It's only "commitmsg" that we don't always pass. Differential Revision: https://phab.mercurial-scm.org/D2909

rebase: get "inmemory" state directly from rebase runtime As far as I can tell, rbsrt.inmemory is equivalent to rbsrt.wctx.isinmemory(), so let's use the shorter form. Differential Revision: https://phab.mercurial-scm.org/D2908

commands: use keyword arguments in update function This will help us in having a dictionary with the values of all the arguments and we can add more flags without adding an argument to the function. Differential Revision: https://phab.mercurial-scm.org/D2896

rebase: pass "inmemory" directly to _definedestmap() We no longer reassign rbsrt.inmemory in _definedestmap(), so we don't need to pass the whole rebase runtime instance anymore, thus making it clear that it won't be updated. Differential Revision: https://phab.mercurial-scm.org/D2905

hgweb: explain instabilities of unstable changesets (the rest of the themes)

test-merge-tools: stabilize for Windows See fe5c4b795999.

test-http-protocol: drop an extraneous glob for Windows

hgweb: evaluate the "default" value as template Strictly speaking, everything in the map file is a template. So let's not take out an unparsed template string.

templater: use named function to expand template against mapping dict (API) And replace __call__(t, **mapping) in favor of generate(t, mapping). I prefer a named function here since the templater isn't a simple function-like object. .. api:: The templater is no longer callable. Use ``templater.generate(t, mapping)`` instead of ``templater(t, **pycompat.strkwargs(mapping))``.

highlight: peek Content-Type header set by hgweb There should be no need to re-render the mimetype template since it's set before dispatching webcommands.

obsolete: add a note that explains creating aliases for marker flags

repair: rename _backup to backupbundle A future commit will introduce a caller from outside the module. The function should have already been public because histedit was calling it. Differential Revision: https://phab.mercurial-scm.org/D2666

templatefuncs: do not stringify result of if*() expression Returning a generator means that the result is a byte string. I can't find any reason to make the "if" condition lazy since it is evaluated anyway when {if()} has to be evaluated. So let's simply make if*() return an input expression unmodified.

templater: add brief doc about internal data types Hopefully this will help reviewing upcoming my series. Start small.

debugcommands: support sending HTTP requests with debugwireproto We implement an action that can issue an HTTP request. We can define headers via arguments and specify a file to use for the HTTP request body. The request uses the HTTP peer's opener, which is already configured for auth, etc. This is both good and bad. Good in that we get some nice behavior out of the box. Bad in that some HTTP request headers are added automatically. Differential Revision: https://phab.mercurial-scm.org/D2841
