vfs: use fchmod for _fixfilemode On general principle, we should use fchmod instead of chmod to avoid security pitfalls, although none is likely possible here.

tests: correctly report a test killed by a signal

histedit: update bookmark movement notice New format is: histedit: moving bookmarks <bookmark> from <old> to <new>

histedit: simplify computation of `newchildren` during --continue We are now checking for any changesets between the previous `parentctx` and the current working directory parent. If the current working directory parent is inconsistent, we abort. This change is useful as it simplifies the --continue process, easing upcoming changes. While working on this changeset, I spotted an unhandled corner case. This corner case is now documented and have an appropriate issue in the tracker (issue3655). However, the corner case is still unhandled. handling this test case would required some additional work: - actually decide what the proper behavior should be: - change content of "histedit-state" to add missing data necessary to detect the situation - add proper testcase, But leaving the case unhandled is "okay": - this is not a regression, - this is not the purpose of the current series, - the freeze was near and I had more critical stuff to attend to, - this is a simple but non trivial, (see above)

test-fncache: enable for Windows Should also fix http://hgbuildbot.kublai.com/builders/vfat%20hg%20tests/builds/182

store: invoke "osutil.listdir()" via vfs This patch invokes "osutil.listdir()" via vfs object. The function added newly to "abstractvfs" is named not as "listdir()" but as "readdir()", because: - "os.listdir()" seems to be more familiar as "listdir()" than "osutil.listdir()" - "osutil.listdir()" returns also type of each files like "readdir()" POSIX API: even though "d_type" field of "dirent" structure is defined mainly only on BSD/Linux This patch invokes "osutil.listdir()" via "rawvfs" object to avoid filename encoding, because the path passed to "osutil.listdir()" shouldn't be encoded. This patch also omits importing "osutil" module, because it is no longer used.

log: speed up hg log for untracked files (issue1340) 'hg log' on untracked files tends to be fairly slow. The root cause is that we end up using the 'slowpath' when we can't find a revlog for the files listed. This could happen if the file in question is an untracked file, or it is a directory. This diff tries to speed up 'hg log' (by avoiding the slowpath) for files if we can determine if that file is not (and was never) a directory. We use the previously added store.__contains__ methods to test if the directory exists (or existed) in the store. To avoid changing any existing semantics, this 'optimization' kicks in only when none of the files listed as arguments to the hg log command exist in the store.

store: add a contains method to fncachestore Adds a __contains__ method to fncachestore to check for file/dir existence (using fncache.__contains__). Also extends fncache.__contains__ to check for directories (by prefix matching)

store: add a contains method to basicstore Adds a __contains__ method to basicstore that checks if a file/dir is present in the store

tests: drop filtercr.py and use the very explicit '\r (no-eol) (esc)' markup

run-tests: allow test output lines to be terminated with \r in addition to \n str.splitlines could not be used in 546c76e5a3e6, but _now_ we would like to have lines with other line endings than \n. Some fine occurences of (esc) markup of \r is replaced with multiple lines ending with '\r (no-eol) (esc)'. That is no win but also no significant loss. This change makes it possible to drop filtercr.py - _that_ is a win.

run-tests: use more explicit criteria for detecting no-eol Preparing for the situation where there could be unsalted lines not terminated with \n.

branchcache: fetch source branchcache during clone (issue3378) Recomputing branch cache on clone may be expensive, therefore if possible we fetch it along with the data. - If the clone is performed by copying, we just copy branchcache file. - If we localrepo.clone and streaming then we follow the procedure: 1. Fetch branchmap from the remote 2. Fetch the actual data. 3. Find the latest rev within branch heads (tip at the time of branchmap fetch) 4. Update the cache for the revs in [remotetip+1, tip] This way we ensure that the branchcache is correct even in case of races with commits.

run-tests: drop unused enumerate

spelling: fix minor spell checker issues

test-dirstate: remove test with date larger than 32 bit When running on a 32bit system or with a touch command that only accepts 32bit dates, the following happened: $ touch -t 250001011200 a touch: invalid date format `250001011200'

merge with crew-stable

bookmarks: deactivate current bookmark if no name is given f57f891eb88e added this help text to hg bookmark: If no NAME is given, the current active bookmark will be marked inactive. But that was never actually the case. Originally spotted by Idan Kamara <idankk86@gmail.com>.

contrib: add a commit synthesizer for reproducing scaling problems This adds two new commands: - analyze examines an existing repo and writes out a statistical description of its properties that contains no identifying information. - synthesize creates new commits based on the description generated by analyze. The intention is that a repo constructed using synthesize will have properties that are vaguely statistically similar to the originating repo, but entirely random content. This can be useful for forecasting performance as a repo grows, and for developers who want to find bottlenecks in proprietary repos to which they do not have access.

dirstate: handle large dates and times with masking (issue2608) Dates and times that are outside the 31-bit signed range are now compared modulo 2^31. This should prevent it from behaving badly with very large files or corrupt dates while still having a high probability of detecting changes.

exewrapper: adapt for legacy HackableMercurial We give up using CPython's PythonXX.lib import libraries (and Python.h), and now "manually" call the LoadLibrary() / GetProcAddress() Windows API's instead. If there is a "hg-python" subdirectory (the canonical directory name for HackableMercurial's private Python copy) next to the hg.exe, we load the pythonXX.dll from there (feeding an absolute path to LoadLibrary) and we set Py_SetPythonHome() to that directory, so that the Python libraries are used from there as well. If there is no "hg-python" subdir found next to the hg.exe, we do not feed an absolute path to LoadLibrary. This continues to allow to find a globally installed Python DLL, as before this change - that is, without having to edit, delete, rename, or configure anything. Note that the hg.exe built is still bound to a *specific* major version of the pythonXX.dll (e.g. python27.dll). What version it is, is inferred from the version of the python interpreter that was used when calling setup.py. For example C:\python27_x86\python.exe setup.py build_hgexe -i --compiler=mingw32 builds a hg.exe (using the mingw32 tool chain) bound to (x86) Python 2.7. And C:\python27_x86\python.exe setup.py build_hgexe -i builds the same using the Microsoft C compiler/linker. (Note that the Microsoft toolchain combined with x64 CPython can be used to build an x64 hg.exe.) setup.py is changed to write the name of the pythonlib into the generated header file "mercurial/hgpythonlib.h", which is #included by exewrapper.c. For a Python 2.7 build, it for example contains: #define HGPYTHONLIB "python27" exewrapper.c then uses HGPYTHONLIB for the name of the Python dll to load. We don't want to track mercurial/hgpythonlib.h, so we add it to .hgignore.

store: restore getsize method This method was created for subclassing.

mq: update bookmarks during qrefresh Bookmarks are updated during qpop and qpush, but they are not updated during qrefresh. This behaviour makes it hard to work on an evolving changeset at the head of a branch. qrefresh should update all bookmarks that point to the refreshed commit with the new nodeid.

templater: drop redundant return in _flatten

store: invoke "os.path.isdir()" via vfs This patch invokes "os.path.isdir()" via "rawvfs" object to avoid filename encoding, because the path passed to "os.path.isdir()" shouldn't be encoded. This patch newly adds "self.rawvfs" field only to "basicstore" and "encodedstore", because "fncachestore" has "self.rawvfs" already.

store: replace invocation of "getsize()" by "vfs.stat()" This patch replaces invocation of "getsize()", which calls "os.stat()" internally, by "vfs.stat()". The object referred by "self.rawvfs" is used internally by "_fncachevfs" and doesn't encode filename for each file API invocation. This patch invokes "os.stat()" via "self.rawvfs" to avoid redundant filename encoding: invocation of "os.stat()" via "self.vfs" hides filename encoding and encoding result from caller, so it is not appropriate, when both encoded and non-encoded filenames should be yield. Even though changeset b42b0729744d improved stream_out performance by "self.pathsep + path", this patch replaces it by "os.path.join(self.base, path)" of vfs. So, this may increase cost to join path components. But this shouldn't have large impact, because: - such cost is much less than cost of "os.stat()" which causes system call invocation - "datafiles()" of store object is invoked only for "hg manifest --all" or "hg verify" which are both heavy functions

store: invoke "os.stat()" for "createmode" initialization via vfs This just replaces "os.stat()" invocation: refactoring around "self.createmode" and "vfs.createmode" initialization is omitted. This patch also newly adds "stat()" function to "abstractvfs".

vfs: define "join()" in each classes derived from "abstractvfs" This patch defines "join()" in each classes derived from "abstractvfs" except "vfs", which already defines it. This allows all vfs instances to be used for indirect file API invocation.

store: initialize vfs field first to use it for initialization of others This patch initializes "vfs" field in the constructor of each store classes to use it for initialization of others. In this patch, "self.vfs.base" is used to initialize "self.path", because redo join of path components for "self.path" is redundant.

scmutil: reorder newly added functions for vfs support in dictionary order Definition functions for vfs support in dictionary order increases readability/maintainability, because there are functions which invoke file API: - with same name: "os.listdir" and "osutil.listdir", for example - with ambiguous names: "os.mkdir" and "util.makedirs", for example

store: rename field name from "opener" to "vfs" in internal classes for fncache These fields are used only in store module, so keeping "self.opener" for backward compatibility like as "localrepository" class is not needed.

store: rename argument name from "op"(ener) to "vfs"
