Can you prevent default-push, but allow pull?

Question

I want to know if there's a way to turn off the default push, but keep the default pull when using Mercurial. I don't want to accidentally pollute the master repository by inadvertently pushing from a an experimental repository.

Answer 1

I was able to solve this by putting the following in my .hg/hgrc file, but I was wondering if there's a better/official way.

[paths]
default = http://server/hg/repo
default-push = .

Answer 2

I like your own answer of setting paths.default-push = . -- it is simple and it is clear that it will work.

Another option would be a pre-push hook:

[hooks]
pre-push = if [ $HG_PATS == "[]" -o $HG_PATS == "['default']" ]; then
               read -p "Really push to default? " -n 1; echo
               [ "$REPLY" == "y" ]
           fi

(Here I'm taking advantage of how you can split a long value over several lines by indenting them in a Mercurial config file.)

A push to default looks this

% hg push
Really push to default? n
warning: pre-push hook exited with status 1

where I typed the n. The hooks checks for both no arguments ($HG_PATS == "[]") and a default as the argument ($HG_PATS == "['default']") and will only prompt you in those cases. The $HG_PATS variable was introduced in Mercurial 1.6.

PS: I saw you updated the question and asked for a solution in PowerShell, but I'm afraid I know nothing about that language. However, you should be able to lift the important concepts from this answer yourself.

Answer 3

Your solution probably is the quickest and is certainly effective. If there's any official way it would be using a preoutgoing hook:

[hooks]
preoutgoing = bash -c 'read -p "Really push to $HG_URL? " -n 1 RESP ; [ "$RESP" == "y" ]'

which will ask you if you want to push and provide the URL to which it would go as a reminder.
