make appendfile simpler so it does not break with revlogng on windows. it used to cache open files. this made revlogng break because it wants to rename files when splitting .i into .i/.d, but cannot rename or unlink open files on windows. new code is bit slower, but safe on linux and windows. proper fix for too many open/close of changelog/manifest belongs in different place. can get 10% speed improvement back.

Fix transaction handling during interleaved file split.

merge 0.8.1 with revlogng

Additional appendfile fixes for interleaved data/index files The appendfile code was not passing default version info to the changelog or manifest classes, and so they were always being created as version 0. revlog.checkinlinesize had to be corrected to seek to the end of the index file when no index file was passed (only clone does this)

Speedup revlog.ancestors for the linear case revlog.ancestors can be expensive on big repos. This cuts down the overall time for hg update by ~19% by short cutting revlog.ancestors when one of the revisions is reachable from another.

Reduce index memory usage by storing the bare string instead of tuples Storing the tuple returned by struct.unpack significantly increases the memory required to store the entire index in ram. This patch uses struct.unpack on demand instead.

New lazy index code for revlogs. This tunes for large repositories. It does not read the whole index file in one big chunk, but tries to buffer reads in more reasonable chunks instead. Search speeds are improved in two ways. When trying to find a specific sha hash, it searches from the end of the file backward. More recent entries are more likely to be relevant, especially the tip. Also, this can load only the mapping of nodes to revlog index number. Loading the map uses less cpu (no struct.unpack) and much less memory than loading both the map and the index. This cuts down the time for hg tip on the 80,000 changeset kernel repo from 1.8s to 3.69s. Most commands the pull a single rev out of a big index get roughly the same benefit. Commands that read the whole index are not slower.

Fill in the uncompressed size during revlog.addgroup This uses code from Matt to calculate the size change that would result from applying a delta to keep an accurate running total of the text size during revlog.addgroup

Fix inlined revlogs to seek to eof after opening "a+"

Create an atomic opener that does not automatically rename on close The revlog.checkinlinesize() uses an atomic opener to replace the index file after converting it from inline to traditional .i and .d files. If this operation is interrupted, the atomic file class can overwrite a valid file with a partially written one. This patch introduces an atomic opener that does not automatically replace the destination file with the tempfile. This way an interrupted checkinlinesize() call turns into a noop.

Make the appendfile class inline-data index friendly The appendfile class needs a few changes to make it work with interleaved index files. It needs to support the tell() method, opening in a+ mode, and it needs to delay the checkinlinesize call until after the append file is written. Given that open(file, "a+") doesn't always seek to the end of the file, this adds seek operations to appendfile that understand whence args

Fix bundle repos to use an index tuple consistent with revlogng The bundle repo code was adding a field to the index tuple, which confused the revlogng changes. This creates a new dict instead to maintain the extra bundle info.

Implement data inlined with the index file This patch allows you to optionally inline data bytes with the revlog index file. It saves considerable space and checkout time by reducing the number of inodes, wasted partial blocks and system calls. To use the inline data add this to your .hgrc [revlog] # inline data only works with revlogng format=1 # inline is the only valid flag right now. flags=inline

Implement revlogng. revlogng results in smaller indexes, can address larger data files, and supports flags and version numbers. By default the original revlog format is used. To use the new format, use the following .hgrc field: [revlog] # format choices are 0 (classic revlog format) and 1 revlogng format=1

Use the new format of setting tags in view extension (Debian bug #361897)

Never exit directly from commands.dispatch(), but pass return code to caller. Usually the caller is commands.run(). Some extensions still use sys.exit(), this is catched, too. Fixed wrong return statement in commands.recover() yielding a zero exit code.

Polished exception handling when importing extensions: - Warning about failed import is printed on one line. - For this warning the [extensions] section key is used, because the value doesn't have to be set. - Whan a --traceback is requested, exit immediately to not mix up problems when importing an extension with other problems.

Added doc/gendoc.py to MANIFEST.in, so docs can be regenerated on demand.

document the possible race in "hg undo"

Don't allow --style and --template for hg update and hg merge. The only way that changesets will be shown with these command is in an error message when trying to update to an ambiguous branch name.

Minor fix for revert: No need to make a backup when forgetting added files. echo foo > foo && hg add foo && hg revert foo creates foo.orig, though foo is not changed or deleted.

small changes to revert command. fix bug 93: work with files that are in target manifest but not dirstate.

bash_completion: completion for commands provided by extensions Make the bash_completion function call _hg_cmd_$cmd to generate completion candidates for $cmd if that function exists. Add basic completion functions for: - mq: - qpop - qpush - qdelete - qsave - qcommit - strip - hbisect: - bisect - patchbomb: - email - gpg: - sign

Don't enter an endless loop if remote hg doesn't answer, show remote noise. The endless loop is not only triggered if the remote shell is too noisy, but even if the local ssh command dies due to an error.

bash_completion: small optimization Right now we always call "hg help $cmd" to get the canonical name of $cmd (i.e. to go from "co" to "update"). This patch optimistically assumes that $cmd is already the canonical form and tries to generate completions for it. If that fails, it falls back to canonicalizing $cmd and trying again. This means that: - if a command or alias is explicitly handled by the _hg_command_specific function, things get somewhat faster - as long as the canonical $cmd is handled by _hg_command_specific, all its aliases and abbreviations are also handled.

Tell the user the real "hg update -C" command, not just "-C" when aborting.

Merged with crew.

Don't abort when backup files already exist. Don't allow alternative names. Rationale: - When the user wants to revert, he shouldn't be stopped from doing this just because some old backups will be overwritten. - To not clobber important files by accident, alternative names for backup files were disabled. As the backup target now has a fixed name, the user doesn't have to be informed about the backup copy (unless --verbose)

Make 'hg tags -q' only list tag names without revision numbers and hashes, and change bash_completion to use this.

add --options to debugcomplete and change bash_completion to use it make debugcomplete print one item per line (this is not needed for the bash_completion script, but should be easier to use in other scripts)

Group changes done by the same developer on the same with --style=changelog Changeset and tags are appended to the change message for non-quiet and non-verbose output, so grouping works. Fixes last bit of issue110.

Fix hg push and hg push -r sometimes creating new heads without --force. Fixing issue179. The algorithm checks if there not more new heads on the remote side than heads which become non-heads due to getting children. Pushing this repo: m /\ 3 3a| |/ / 2 2a |/ 1 to a repo only having 1, 2 and 3 didn't abort requiring --force before. Added test cases for this and some doc strings for used methods.

These hgignore files apply to all repositories used by that user.

Calling revlog.addgroup with an empty changegroup now raises RevlogError. The empty changegroup can be caused by remote servers dying soon after findincoming, and further code in pull assumes (correctly) that there are new changesets.

Windows py2exe version didn't handle names given to templatepath() correctly

add benoit's test for issue148.

forgot to add new module.

fix race in localrepo.addchangegroup. localrepo.addchangegroup writes to changelog, then manifest, then normal files. this breaks access ordering. if reader reads changelog while manifest is being written, can find pointers into places in manifest that are not yet written. same can happen for manifest and normal files. fix is to make almost no change to localrepo.addchangegroup. it must to write changelog and manifest data early because it has to read them while writing other files. instead, write changelog and manifest data to temp file that reader cannot see, then append temp data to manifest after all normal files written, finally append temp data to changelog. temp file code is in new appendfile module. can be used in other places with small changes. much smaller race still left. we write all new data in one write call, but reader can maybe see partial update because python or os or filesystem cannot always make write really atomic. file locking no help: slow, not portable, not reliable over nfs. only real safe other plan is write to temp file every time and rename, but performance bad when manifest or changelog is big.

Added missing gettext import to changegroup.py.

add checking for invalid entries in tag files safely parse the differents tag files, output warning when parsing an invalid entry.

Adapted behaviour of ui.username() to documentation and mention it explicitly: Searched in this order: $HGUSER, [ui] section of hgrcs, $EMAIL and stop searching if one of these is set. Abort if found username is an empty string to force specifying the commit user elsewhere, e.g. with line option or repo hgrc. If not found, use $LOGNAME or $USERNAME +"@full.hostname".

Improved ui.edit(): - Use descriptive name for temporary file: hg-editor-*.txt - Don't import tempfile in the method, but use demandload() - Remove tempfile file even if editor aborts.

Pass correct username as $HGUSER to hgeditor if "commit -u" is used. And only use the new util.system parameter to set the environment.

Added test for incoming via ssh.

make incoming work via ssh (issue139); move chunk code into separate module. Incoming ssh needs to detect the end of the changegroup, otherwise it would block trying to read from the ssh pipe. This is done by parsing the changegroup chunks. bundlerepo.getchunk() already is identical to localrepo.addchangegroup.getchunk(), which is followed by getgroup which looks much like what you can re-use in bundlerepository.__init__() and in write_bundle(). bundlerevlog.__init__.genchunk() looks very similar, too, as do some while loops in localrepo.py. Applied patch from Benoit Boissinot to move duplicate/related code to mercurial/changegroup.py and use this to fix incoming ssh.

use HG10UN header for uncompressed bundle - use HG10UN instead of HG11 for uncompressed bundles header - check HG10BZ for compressed bundle - better error handling for invalid header some notes: - people who created uncompressed bundle will no longer be able to use them (it could be fixed with hand-editing) - older hg cannot detect an uncompressed bundle (bzip2 decompression will fail).

Duplicate cache when creating templater.

Delete bundle file of hg incoming in case of errors, preserve existing files. Let write_bundle always create the bundle file, check if target doesn't exist and delete it in case of errors. This way incoming only has to delete the bundle file if it was meant to be a temporary file.
