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"

verify: rename "hasmanifest" variable for source code readability Before this patch, there are two ambiguous variables: "havemf" and "hasmanifest". "havemf" means whether there are any "manifest" entries. "hasmanifest" means whether there are any "changelog" entries referring to "manifest" entry. This patch renames from "hasmanifest" to "refersmf" to clear difference from "havemf".

verify: use appropriate local variable in "checkentry()" Before this patch, "checkentry()" internal function uses both "node"(argument of itself) and "n"(defined in outer of it) variables. Because all callers of "checkentry()" use "n" to refer the object which is passed to "checkentry()" as "node", both can refer same object in "checkentry()". So, "checkentry()" works correctly. But such usage is not good for independence of "checkentry()". This patch replaces "n" in "checkentry()" with "node".

verify: use appropriate node information to show verification error Before this patch, verify module shows verification error message below: unknown parent 2 <HASH_OF_P2> of <HASH_OF_P1> even though it should show: unknown parent 2 <HASH_OF_P2> of <HASH_OF_TARGET> This patch uses appropriate node information.

help: add information about recovery from corruption to help of "verify" Before this patch, there is no information about what users should (or can) do for recovery from corruption of repositories. This patch adds URL of the Mercurial Wiki page explaining about recovery from corruption.

hidden: remove tags use in hidden computation Tags initially prevented revision to be hidden. It seemed a bad idea to have tags refer to revisions that one can't see. But proper filtering of hidden revisions excludes them from tag computation. Coming changelog filtering will do that. Anyway, tags that really matter will likely be public and therefore not hidden. The current working directory parent and bookmarked revision are still not hidden. Bookmarks were likely automatically moved at rewrite time, bookmarks that remain on obsolete revisions were probably moved there on purpose.

clfilter: do not use tags cache if there are filtered changesets If there are filtered changesets the cache is not valid. We'll have to cache tags for filtered state too, but for now recomputing the tags is enough.
