histedit: backout changeset 2b599f5468a4 Its parent is about to be backedout so this one needs to be removed too.

revsetlang: fix _quote on int on python3 Thanks to Yuya for spotting the need.

runtests: unset editor and pager related environment variables Those environment variables could affect some configuration and future tests. Drop them to avoid issues.

debugfsinfo: improve case-sensitive testing Previously the case-sensitive test was for the current directory, and is fragile with errors, and could remove a real file called ".debugfsinfo". This patch improves the case-sensitive testing so it test the given path using a unique temporary file, and does not crash on errors.

debugfsinfo: show fstype for given path

test-check-py3-commands: cleanup tests related to `hg status` We were testing hg status on Python 3 at two places in the test. Cleaned up one of them.

diff: use pycompat.{byteskwargs, strkwargs} to switch opts b/w bytes and str

patch: make regular expressions bytes by adding b''

dispatch: use pycompat.maplist() instead of map() to get a list

color: fix grammar in help text

statfs: detect more filesystems on Linux Previously, the code only has what manpager says. In <linux/magic.h>, there are more defined. This patch adds filesystems that appear in the current Arch Linux's /proc/filesystems (autofs, overlay, securityfs) and f2fs, which was seen in news.

repair: use context manager for lock management If repo.lock() raised inside of the try block, 'tr' would have been None in the finally block where it tries to release(). Modernize the syntax instead of just winching the lock out of the try block. I found several other instances of acquiring the lock inside of the 'try', but those finally blocks handle None references. I also started switching some trivial try/finally blocks to context managers, but didn't get them all because indenting over 3x for lock, wlock and transaction would have spilled over 80 characters. That got me wondering if there should be a repo.rwlock(), to handle locking and unlocking in the proper order. It also looks like py27 supports supports multiple context managers for a single 'with' statement. Should I hold off on the rest until py26 is dropped?

gitweb: use monospace font for commit messages Commit messages often contain vertically aligned text. The default paper style already uses monospace fonts for rendering commit messages. And, AFAICT, a number of Git servers also render commit messages with monospace. It seems like the reasonable thing to do. This commit converts all instances of the full commit message in the gitweb style to render with monospace.

pager: improve support for various flavors of `more` on Windows Hardcoding 'more' -> 'more.com' means that 'more.exe' from MSYS would need to be configured with its *.exe extension. This will resolve to either one, as cmd.exe would have done if the command ran through the shell. Something that's maybe problematic with this is it comes after 'pageractive' and various ui configs have been set by the calling method. But the other early exits in this method don't undo those changes either.

statfs: avoid static allocation Previously we have "static struct statfs" to return a string. That is not multiple-thread safe. This patch moves the allocation to the caller to address the problem.

statfs: change Linux feature detection Previously we check three things: "statfs" function, "linux/magic.h" and "sys/vfs.h" headers. But we didn't check "struct statfs" or the "f_type" field. That means if a system has "statfs" but "struct statfs" is not defined in the two header files we check, or defined without the "f_type" field, the compilation will fail. This patch combines the checks (2 headers + 1 function + 1 field) together and sets "HAVE_LINUX_STATFS". It makes setup.py faster (less checks), and more reliable (immutable to the issue above).

rebase: don't require destination if commands.rebase.requiredest=False

tests: add tests with commands.{update,rebase}.requiredest=False This shows how rebase is currently broken with commands.rebase.requiredest=False.

rebase: move state serialization to use unfiltered repo Now that rebasestate is serialized as part of the transaction, the repo state it sees is the version at the end of the transaction, which may have hidden nodes. Therefore, it's possible parts of the rebase commit set are no longer visible by the time the transaction is closing, which causes a filtered revision error in this code. I don't think state serialization should be blocked from accessing commits it knows exist, especially if all it's trying to do is get the hex of them, so let's use an unfiltered repo here. Unfortunately, the only known repro is with the fbamend Facebook extension, so I'm not sure how to repro it in core Mercurial for a test.

largefiles: avoid redundant standin() invocations There are some code paths, which apply standin() on same value multilpe times instead of using already standin()-ed value. "fstandin" is common name for "path to standin file" in lfutil.py, to avoid shadowing "standin()".

largefiles: replace hashrepofile by hashfile (API) There is only one user for the former, and repo.wjoin()-ed value is alread known by that user.

largefiles: call readstandin() with changectx itself instead of rev or node readstandin() takes "node" argument to get changectx by "repo[node]". There are some readstandin() invocations, which use ctx.node(), ctx.rev(), or '.' as "node" argument above, even though corresponded changectx object is already looked up on caller side. This patch calls readstandin() with already known changectx itself, to avoid meaningless re-construction of changectx (indirect case via copytostore() is also included). BTW, copytostore() uses "rev" argument only for readstandin() invocation. Therefore, this patch also renames it to "revorctx" to indicate that it can take not only revision ID or so but also changectx, for readability.

largefiles: omit redundant splitstandin() invocations There are 3 splitstandin() invocations in updatestandin() for same "standin" value.

largefiles: replace splitstandin() by isstandin() to omit str creation If splitstandin()-ed str itself isn't used, isstandin() should be used instead of it, to omit meaningless str creation.

largefiles: omit redundant isstandin() before splitstandin() There are many isstandin() invocations before splitstandin(). The former examines whether specified path starts with ".hglf/". The latter returns after ".hglf/" of specified path if it starts with that prefix, or returns None otherwise. Therefore, value returned by splitstandin() can be used for replacement of preceding isstandin(), and this replacement can omit redundant string comparison after isstandin().

misc: update descriptions about removed file for filectxfn Since 650b5b6e75ed, filectxfn for memctx should return None for removed file instead of raising IOError.

osx: always purge build/mercurial before starting build This prevents stray files from previous builds from polluting newer builds.

osx: use more paranoid quoting in test
