amend: save commit message into ".hg/last-message.txt" Before this patch, commit message (may be manually edited) for "commit --amend" is never saved into ".hg/last-message.txt", because it uses "localrepository.commitctx()" instead of "localrepository.commit()": saving into ".hg/last-message.txt" is executed only in the latter. This patch saves commit message for "commit --amend" into ".hg/last-message.txt" just after user editing. This is the simplest implementation to fix on stable. Editing and saving commit message for memctx should be centralized into the framework like "localrepository.commit()" with "editor" argument or so in the future.

histedit: save manually edited commit message into ".hg/last-message.txt" Before this patch, manually edited commit message for "fold" command in histedit-ing is never saved into ".hg/last-message.txt", because it uses "localrepository.commitctx()" instead of "localrepository.commit()": saving into ".hg/last-message.txt" is executed only in the latter. This patch saves manually edited commit message for "fold" command in histedit-ing into ".hg/last-message.txt" just after user editing. This is the simplest implementation to fix on stable. Editing and saving commit message for memctx should be centralized into the framework like "localrepository.commit()" with "editor" argument or so in the future.

qfold: save manually edited commit message into ".hg/last-message.txt" Before this patch, manually edited commit message for "hg qfold -e" isn't saved into ".hg/last-message.txt" until it is saved by "localrepository.savecommitmessage()" in "localrepository.commit()". This may lose such commit message, if unexpected exception is raised. This patch saves manually edited commit message for "hg qfold -e" into ".hg/last-message.txt" just after user editing. This patch doesn't save the message specified by -m/-l options as same as other commands. This is the simplest implementation to fix on stable. Editing and saving commit message should be centralized into the framework of "localrepository.commit()" with "editor" argument in the future. This patch uses repository wrapping class for exception raising before saving commit message in "localrepository.commit()" easily and certainly, because such exception requires corner case condition.

qnew: save manually edited commit message into ".hg/last-message.txt" Before this patch, manually edited commit message for "hg qnew -e" isn't saved into ".hg/last-message.txt" until it is saved by "localrepository.savecommitmessage()" in "localrepository.commit()". This may lose such commit message, if unexpected exception is raised. This patch saves manually edited commit message for "hg qnew -e" into ".hg/last-message.txt" just after user editing.

tag: save manually edited commit message into ".hg/last-message.txt" Before this patch, manually edited commit message for "hg tag -e" isn't saved into ".hg/last-message.txt" until it is saved by "localrepository.savecommitmessage()" in "localrepository.commit()". This may lose such commit message, if unexpected exception is raised. This patch saves manually edited commit message for "hg tag -e" into ".hg/last-message.txt" just after user editing. This patch doesn't save the message specified by -m option (-l is not supported for "hg tag") as same as other commands. This is the simplest implementation to fix on stable. Editing and saving commit message should be centralized into the framework of "localrepository.commit()" with "editor" argument in the future.

rebase: use "commitforceeditor" instead of "ui.edit()" for "--collapse" Before this patch, "rebase --collapse --edit" without "--message" and "--logfile" invokes editor twice unexpectedly: 1. explicit "ui.edit()" invocation in rebase extension itself 2. indirect invocation in "localrepository.commit()" with "editor = commitforceeditor" assigned by "--edit" option This patch uses indirect "commitforceeditor" invocation instead of "ui.edit()" for "--collapse" without "--message" and "--logfile" to: - suppress redundant the former invocation - ensure editor invocation even when "--edit" is not specified

localrepo: save manually edited commit message as soon as possible Before this patch, "localrepository.commit()" invokes specified "editor" to edit commit message manually, and saves it after checking sub-repositories. This may lose manually edited commit message, if unexpected exception is raised while checking (or commiting recursively) sub-repositories. This patch saves manually edited commit message as soon as possible.

hgk: enable selected patch text on Windows Port a patch from gitk. Original description: On windows, mouse input follows the keyboard focus, so to allow selecting text from the patch canvas we must not shift focus back to the top level. This change has no negative impact on X, so we don't explicitly test for Win32 on this change. This provides similar selection capability as already available using X-Windows.

hgk: ignore ctrl-z as EOF on windows Port a patch from gitk. Original description: Cygwin's Tcl is configured to honor any occurence of ctrl-z as an end-of-file marker, while some commits in the git repository and possibly elsewhere include that character in the commit comment. This causes gitk ignore commit history following such a comment and incorrect graphs. This change affects only Windows as Tcl on other platforms already has eofchar == {}. This fixes problems noted by me and by Ray Lehtiniemi, and the fix was suggested by Shawn Pierce. Signed-off-by: Mark Levedahl <mdl123@verizon.net> Signed-off-by: Paul Mackerras <paulus@samba.org>

graphmod: changed code in dagwalker to use lazy implementations Used lazy methods when possible.

webcommands: changed code to use lazy classes when calling dagwalker This needs to be changed to use a baseset since dagwalker now expects to receive a smartset. This is basically wrapping revs into a baseset to be compatible with smartset implementations.

cmdutil: changed max method for lazy call Used the lazy max call instead of the python max implementation to be able to use lazysets for graphlog.

getgraphlogrevs: return an empty baseset instead of a empty list We aims at returning smartset only so that function higher in the stack can use smartset feature.

getgraphlogrevs: do not convert smartset to baseset We are now sure that revs is a smartset. We remove the baseset call that would defeat any lazyness.

cmdutil: changed revset for spanset Instead of using baseset(repo.changelog) changed it for spanset(repo) which is much faster.

cmdutil: changed code in _makegraphlogrevset not to use getitem __getitem__ is a method that is not implemented lazily on many of the new classes and it can be easily replaced with a structure that takes advantage of the new lazy implementations instead.
