Before this patch, each template definitions for 'changeset*' in
'[committemplate]' section have to be written fully from scratch,
even though many parts of them may be common.
This patch uses '[committemplate]' section like as the map file for
the style definition. All items other than 'changeset' can be referred
from others.
This can reduce total cost of template customization in
'[committemplate]' section.
When the commit template other than '[committemplate] changeset'
is chosen by 'editform', putting '[committemplate] changeset'
value into the cache of the templater causes unexpected result,
because the templater stores the specified (= chosen) template
definition into own cache as 'changeset' at construction time.
This is the reason why '[committemplate] changeset' can't be referred
from others.
This patch makes commit message shown in text editor customizable by
template. For example, this can advertise:
- sample commit messages for routine works,
- points to call attention before commit,
- message of the day, and so on
To show commit message correctly even in problematic encoding, this
patch chooses the latter below:
- replace "buildcommittext" with "buildcommittemplate" completely
- invoke "buildcommittemplate" only if '[committemplate] changeset'
is configured explicitly
For example, if multibyte character ending with backslash (0x5c) is
followed by ASCII character 'n' in the customized template, sequence
of backslash and 'n' is treated as line-feed unexpectedly (and
multibyte character is broken, too).
This corruption occurs in 'decode("string-escape")' while parsing
template string.
Before this patch, 'hg qrefresh' disallows to specify
'--message/'--logfile' and '--edit' at the same time.
'hg qrefresh' has disallowed such combination since Mercurial 0.9.2,
but this restriction seems not to be reasonable for recent Mercurial,
because all other commands creating new changeset allow it.
This patch allows 'hg qrefresh' to specify '--message/'--logfile' and
'--edit' at the same time like other commands creating new changeset.
This patch also replaces "editor = False" by "editor =
cmdutil.getcommiteditor()", because:
- it allows to hook commit message determination easily, even in the
case without "--edit"
- it avoids regression (or additional care) around saving
"last-message.txt", even if MQ's "newcommit()" changes its
implementation logic from "localrepository.commit" to
"localrepository.commitctx" with "memctx" in the future
to save commit message into "last-messge.txt" with "memctx",
"editor" should be valid function.
Before this patch, "hg qrefresh" and "hg qfold" invoke "ui.edit()"
explicitly to get commit message edited manually.
This requires explicit "localrepository.savecommitmessage()"
invocation to save edited commit message into ".hg/last-message.txt",
because unexpected exception raising may abort command execution
before saving it in "localrepository.commit()".
This patch uses "editor" argument of "localrepository.commit()"
instead of explicit "ui.edit()" invocation for "hg qnew" and "hg qfold"
"localrepository.commit()" will invoke "desceditor()" function newly
added by this patch, and save edited commit message into
".hg/last-message.txt" automatically.
This patch passes not "editor" but "desceditor" to "commit()", because
"hg qnew" and "hg qfold" require editor function to return edited
message (and invoke "patchheader.setmessage()" with it) if not empty,
or default message otherwise.
This patch also avoids "not q.applied" check at "hg qrefresh --edit",
because it is also checked in "queue.refresh()", and it is not needed
to get commit message from patch header before "queue.refresh()".
