mq: document repo.mq.qparents The function is not very complex but writing this doc helped me to check if I got everything right.

mq: use the new checklocalchange in the strip command The strip command never use the `refresh` argument. So we can use the function we just extracted.

mq: extract checklocalchanges from `mq.queue` The core part of `checklocalchanges` is now mq independent. We can extract it in a standalone function to help the extraction of `strip` as discussed in issue3824. A `checklocalchanges` function stay in `mq.queue` with the part related to "refresh first" messages.

mq: extract checksubstate from the queue class This function does not need any of the the `mq.queue` method or attributes. It is indirectly used by the `strip` command. We are trying to extract this command in a standalone extension as discussed in issue issue3824.

mq: simplifies the refresh hint in checklocalchanges The `checklocalchanges` function in the `mq.queue` class takes a `refresh` argument that changes the error message of raised exception. When refresh is `True` the exception message is "local changes found, refresh first" otherwise, the message is just "local changes found". This changeset is the first of a series that extract `strip` into a standalone extension (as discussed in issue3824). This `checklocalchanges` function is indirectly used by the strip command. But in a standalone strip extension the concept of "refresh first" has no sense. In practice, When used in the context of the strip commands `refresh`'s value is always `False`. So my final goal is a be able to extract the `checklocalchanges` logic in a standalone extension but to keep the part related to "refresh first" in the mq extension. However the refresh handling is deeply entangled into the `checklocalchanges` code. It is handled as low a possible at the point we raise the exception. So we moves handling of refresh upper in the `checklocalchanges` code. This will allow the extraction of a simple version in the strip extension while mq can still inject its logic when needed. Two helper functions `localchangesfound` and `localchangedsubreposfound` died in the process they are replaced by simple raise lines.

merge: let the user choose to merge, keep local or keep remote subrepo revisions When a subrepo has changed on the local and remote revisions, prompt the user whether it wants to merge those subrepo revisions, keep the local revision or keep the remote revision. Up until now mercurial would always perform a merge on a subrepo that had changed on the local and the remote revisions. This is often inconvenient. For example: - You may want to perform the actual subrepo merge after you have merged the parent subrepo files. - Some subrepos may be considered "read only", in the sense that you are not supposed to add new revisions to them. In those cases "merging a subrepo" means choosing which _existing_ revision you want to use on the merged revision. This is often the case for subrepos that contain binary dependencies (such as DLLs, etc). This new prompt makes mercurial better cope with those common scenarios. Notes: - The default behavior (which is the one that is used when ui is not interactive) remains unchanged (i.e. merge is the default action). - This prompt will be shown even if the ui --tool flag is set. - I don't know of a way to test the "keep local" and "keep remote" options (i.e. to force the test to choose those options). # HG changeset patch # User Angel Ezquerra <angel.ezquerra@gmail.com> # Date 1378420708 -7200 # Fri Sep 06 00:38:28 2013 +0200 # Node ID 2fb9cb0c7b26303ac3178b7739975e663075857d # Parent 50d721553198cea51c30f53b76d41dc919280097 merge: let the user choose to merge, keep local or keep remote subrepo revisions When a subrepo has changed on the local and remote revisions, prompt the user whether it wants to merge those subrepo revisions, keep the local revision or keep the remote revision.

python2.4: fix imports of sub-packages of the email package These all have an obvious comment so if/when we finally ditch Python 2.4 we can eradicate them easily.

httpconnection: properly inject ssl_wrap_socket into httpclient (issue4038) This causes httpclient to use the same SSL settings as the rest of Mercurial, and adds an easy extension point for later modifications to our ssl handling.

sslutil: make keyfile and certfile arguments consistent between 2.6+ and 2.5-

httpclient: import 4bb625347d4a to provide SSL wrapper injection This lets us inject our own ssl.wrap_socket equivalent into httpclient, which means that any changes we make to our ssl handling can be *entirely* on our side without having to muck with httpclient, which sounds appealing. For example, an extension could wrap sslutil.ssl_wrap_socket with an api-compatible wrapper and then tweak SSL settings more precisely or use GnuTLS instead of OpenSSL.
