run-tests: drop required (feature !) style lines when the output is missing Essentially, these were acting as a verbose (?) flag, since they weren't being dropped when required. Foozy has a nice description [1]. Basically, a couple more places needed to check the features before treating it as optional. I don't like how test-run-tests.py had to be hacked, but _hghave() can't be made a static method. The test change was a change while developing `debugssl`, prior to tightening up the cases where the message is printed, that this fix would have caught.

status: avoid recursing into ignored directory with "--terse u" Let "isignoreddir" function first check that supplied directory is itself ignored before walking recursively into its content. Otherwise, the command is awfully slow when one has an ignored directory with a lot of content. Update and rephrase function docstring accordingly.

pushvars: move fb extension pushvars to core pushvars extension in fbext adds a --pushvars flag to push command using which one send strings to server which becomes environment variables there prepended with HG_USERVAR_. These variables can then be used to run hooks on the server. The extension is moved directly to core and unbundling of the strings and converting them to environment variables at server is disabled by default for security reasons. One can turn that on by following config: [push] pushvars.server = true This patch also adds the test for the extension. Differential Revision: https://phab.mercurial-scm.org/D210

phabricator: update diff property even if we choose not to create a new diff The diff property contains metadata like "HG Node". Previously we skip uploading a new diff if we are sure that the old patch and new patch have a same content. That has issues when a pusher adds an obsmarker using the old "HG Node" stored in the old diff. This patch adds logic to update the diff property so "HG Node" gets updated to prevent that issue.

phabricator: use Phabricator's last node information This makes it more strict when checking whether or not we should update a Differential Revision. For example, a) Alice updates D1 to content 1. b) Bob updates D1 to content 2. c) Alice tries to update D1 to content 1. Previously, `c)` will do nothing because `phabsend` detects the patch is not changed. A more correct behavior is to override Bob's update here, hence the patch. This also makes it possible to return a reaonsable "last node" when there is no tags but only `Differential Revision` commit messages. Test Plan: ``` for i in A B C; do echo $i > $i; hg ci -m $i -A $i; done hg phabsend 0:: # D40: created # D41: created # D42: created echo 3 >> C; hg amend; hg phabsend . # D42: updated hg tag --local --hidden -r 2 -f D42 # move tag to the previous version hg phabsend . # D42: skipped (previously it would be "updated") rm -rf .hg; hg init hg phabread --stack D42 | hg import - hg phabsend . # D42: updated hg tag --local --remove D42 hg commit --amend hg phabsend . # D42: updated (no new diff uploaded, previously it will upload a new diff) ``` The old diff object is now returned, which could be useful in the next patch.

phabricator: add --confirm option to phabsend command This adds a --confirm flag similar to the confirm flag of `hg email` using which one can confirm the changesets before they get emailed. The confirm flag will show the changesets and ask for confirmation before sending them. Differential Revision: https://phab.mercurial-scm.org/D218

evolution: rename bumped to phase-divergent Rename bumped to phase-divergent in all external user-facing output. Only update user-facing output for the moment, variables names, templates keyword and potentially configuration would be done in later series.

py3: use bytes IO to write sample hgrc Unicode sucks. Stop using Text IO and manually convert line endings.

buildrpm: do not break in presence of custom user configs For example, if "hg log" was defined as an alias: # /etc/mercurial/hgrc [alias] log = log --graph the buildrpm script would be surprised by log messages formatted in unexpected ways, and bail out. This patch sets HGPLAIN, effectively resetting all the user configs, including log output, to a common state, making the build more predictable across all the possible environments.

sparse: treat paths as cwd-relative This commit makes it so sparse treats passed paths as CWD-relative, not repo-root-realive. This is a more intuitive behavior in my (and some other FB people's) opinion. This is breaking change however. My hope here is that since sparse is experimental, it's ok to introduce BCs. The reason (glob)s are needed in the test is this: in these two cases we do not supply path together with slashes, but `os.path.join` adds them, which means that under Windows they can be backslashes. To demonstrate this behavior, one could remove the (glob)s and run `./run-tests.py test-sparse.t` from MinGW's terminal on Windows.

match: expose some data and functionality to other modules This patch makes sure that other modules can check whether patterns are CWD-relative.

sparse: properly error out when absolute paths are used Current logic is misleading (it says it drops only absolute paths, but it actually drops all of them), not cross-platform (does not support Windows) and IMO just wrong (as it should just error out if absolute paths are given). This commit fixes it.

py3: convert arbitrary exception object to byte string more reliably Our exception types implement __bytes__(), which should be tried first. Do lossy encoding conversion as a last resort.

build: delay version computation on macOS builds The way HGVER is evaluated now, it'll be evaluated at the beginning of the make execution - with this change, it's evaluated when it gets to that command, at which point the version file it's looking for is sure to exist and be up-to-date.
