run-tests: allow run-tests.py to run tests outside current directory When reloading tests, run-tests.py was assuming that it could look up the test by the basename, which only works if you are running tests which are in the current directory. This patch changes that lookup to use the full path. This is all that was needed, and does not appear to cause any problems for any of the existing testing work flows based on running the suggested commands at the top of run-tests.py. Motivation: In order to test Mercurial with Hypothesis (according to https://www.mercurial-scm.org/wiki/HypothesisPlan) it is useful to be able to generate temporary test files and execute them. Generating temporary files in the tests/ directory leads to a lot of suboptimal clutter.

histedit: unifying the way replacements are computed for abort and success This is a part of a bigger refactoring effort with the ultimate goal of better understanding of how histedit works and fixing issue4800.

templater: factor out type conversion of revset() result This makes it clear why we have to do repo[int(x)].

templater: evaluate each item of revset() as integer revision Because templater.revset() returns a list of strings, repo["-1"] was mapped to the tipmost revision. Ideally, we should make revset() return a list of integer revisions, but it turned out not simple. If revset() is a list of integers, "{ifcontains(rev, revset(), ...)}" would fail because "ifcontains" casts "rev" to a string. So this patch just converts a string back to an integer revision.

demandimport: blacklist sqlalchemy.events as it has side effects (issue5085) Importing sqlalchemy.events cannot be delayed as it registers classes to their event mechanism. It worked fine before 4f1144c3c72b, since they use new-style imports. But now we have to blacklist it because our demandimport can handle new-style imports. This patch series isn't intended for stable as we don't guarantee API compatibility with 3rd-party extensions. They can temporarily disable the demand importer to work around the issue.

demandimport: enforce ignore list while processing modules in fromlist If a module is loaded as "from . import x" form, there has been no way to disable demand loading for that module because name is ''. This patch makes it possible to prevent demand loading by '<package-name>.x'. We don't use _hgextimport(_origimport) here since attr is known to be a sub-module name. Adding hgext_ to attr wouldn't make sense.

phases: use constants for phase values Magic numbers hinder readability.

test-paths: fix up json output to match $TESTTMP on Windows Without this, the paths were in the form "C:\\Users\\Matt\\AppData...". The test runner wouldn't collapse it down to $TESTTMP, which uses single backslashes.

test-obsolete: conditionalize a test dependent on chmod

progress: display progress bar when HGPLAINEXCEPT contains "progress" This patch changes "progress.shouldprint()" so a feature name is provided to "ui.plain()" to determine if there is an exception specificed in HGPLAINEXCEPT for the progress extension. This will allow user-facing scripts to provide progress output while HGPLAIN is enabled.

run-tests: stop allocating HGPORT3+HGPORT4 The only consumer was test-treemanifest.t, which has been fixed. In general, you should be able to use killdaemons.py to recycle ports instead of going over 3 ports (HGPORT, HGPORT1, HGPORT2). In the future, if you want to add a port, be sure to change portneeded in _getport.

run-tests: refactor port allocation into functions Adding a port reservation was too hard and someone did it wrong. By refactoring, such reservations can be managed more safely. This also adds documentation so that the next person who tries is more likely to update all the places correctly. Note that in this commit the reservation and consumers do not match, that will be fixed in the next commit.

tests: put test-treemanifest.t on a port diet test-treemanifest.t had introduced HGPORT3 and HGPORT4, which were improperly added to run-tests.py. It also was not using HGPORT1. This recycles HGPORT, and shifts everything into HGPORT1 + HGPORT2.

chg: pass sensitive command line flags to server We are going to make chgserver load repo config, remember what it is, and load repo config again to detect config change. This is the first step that passes config, repo, cwd options to server. Traceback is passed as well to cover errors before hitting chgserver.runcommand.

chg: use mallocx and reallocx in hgclient This patch simplifies the code a bit, and reduces the binary size a little.

chg: add utility functions mallocx, reallocx They are like malloc and realloc but will abort the program on error. A lot of places use {m,re}alloc and check their results. This patch can simplify them.
