These leaks may occur in environments that don't employ a reference
counting GC, i.e. PyPy.
This implies:
- changing opener(...).read() calls to opener.read(...)
- changing opener(...).write() calls to opener.write(...)
- changing open(...).read(...) to util.readfile(...)
- changing open(...).write(...) to util.writefile(...)
When mq status entry referencing a patches that is not in series `hg qfinish
-a` used to issue a traceback. This states is inconsistent but might happen
regularly when people misuse hg up -mq.
This changeset prevent hg from crashing. The faulty entry is finished anyway and
a warning is issued.
This patch prevent mq to crash when .hg/patches/status contains Malformed lines
(without ":"). Blank lines are ignored and other malformed lines issue a
warning.
Add missing calls to close() to many places where files are
opened. Relying on reference counting to catch them soon-ish is not
portable and fails in environments with a proper GC, such as PyPy.
We can't assume that all pushable patches early in the series have already been
applied. If a hg qselect is done while you already have patches applied, some
patches with guards may now be pushable, even though they come earlier in the
series.
So instead of checking only applied patches, explicitly check where we are in
the series against the position of the patch we want to qpush to.
Some extensions (e.g. hgsubversion) completely override push command. Because
extensions load order is unspecified, if hgsubversion loads before mq, mq
checks about not pushing applied patches will be bypassed. Short of finding a
way to fix load order, extracting the checking logic will allow
hgsubversion-like extensions to run the check themselves.
* parse branch and nodeid header lines
* remember the line number where diffs started
Combined, these make mq.patchheader() very useful for parsing and
preserving a patch header through edits. TortoiseHg will use the
nodeid and parent to display these header datums in the graph when
patches are unapplied, and uses diffstartline to parse patch files
using record.parsepatch().
This patch prevents MQ from creating an inconsistent subrepo state. If
the .hgsub file has been changed, and none of the subrepos have
uncommitted changes, creating or updating a patch (using qnew, qrefresh,
or qrecord) will update .hgsubstate accordingly.
If any subrepos _do_ have uncommitted changes, qnew/qrefresh/qrecord
will abort.
Thanks to pmezard for proposing this solution.
If MQ allows modifying .hgsub or .hgsubstate in a patch, it can easily
lead to an inconsistent subrepo state. This patch prevents qrefresh from
adding any modifications to .hgsub or .hgsubstate to a patch. The user
is warned that these files are not included in the patch.
The tests test both the slightly irrational and the pathological cases.
