Previous patch erroneously assumed that cover:start() returned
{already_started,Pid} in the cases where cover was already started. We
now turn {error,{already_started,Pid}} into {ok, Pid} and return
{error, Reason} if we encounter an error we do not know about, this
will cause a nice and violent badmatch to stop everything.
The cover module calls io:format and io:fwrite directly for several types of
informational messages and warnings. When using meck to mock covered modules
these warnings are triggered and can cause severe polution of the test output.
We can avoid this by starting cover explicitly then setting the group_leader
of that process to a file handle.
Generate .hrl files into include from SNMP MIB files.
Change the order of so .mib files are built before .erl
This is necessary since .hrl files are generated from
the .mib files.
The generated .bin and .hrl files are deleted by clean.
This is a cleaned up version of a patch originally
sent to the rebar mailing list by David Nonnenmacher.
The target_dir config in reltool allows you to put your release in
a directory other than in ./NAME, so we should look in the parent
directory of that to find the new and old versions instead of
simply looking in ./
Move untaring and retaring into a temporary path instead of in ./
to prevent name collisions with "releases" and "lib" that might
exist already. Having a subdirectory rel/releases/ can be useful.
Allows customizing the arguments handed over to the Erlang VM, e.g. to
set a name or a cookie, e.g. by setting escript_emu_args to:
%%! -name rebar -setcookie rebar
Calling erlang:system_info(wordsize) yields the internal word size of
the Erlang emulator. But due to the halfword emulator, need to pass
{wordsize, external} instead to get the word size, or pointer size, as
seen by external code such as NIFs. The halfword emulator has 4 byte
internal words but 8 byte external words due to 64-bit compilation,
which means NIFs for the halfword emulator also have to be compiled
64-bit. But just passing wordsize is equivalent to passing {wordsize,
internal}, which does not indicate the pointer size for the halfword
emulator.
Older versions of Erlang do not support {wordsize, external}, though,
so continue to pass just wordsize for those versions.
Change the second parameter of a regex tagged port_source from being a
filename or wildcard to being a list of filenames or wildcards.
Previously: {"R14", "c_src/*.c"}
Now: {"R14", ["c_src/*.c"]}
Motivation for change is to avoid repeating regexes.
get_apps/3 now returns which apps have been added, removed and ugpgraded
in a reasonable way. It should prove more usable should we want to
access any of those lists in future appup related changes.
This patch makes a small change in rebar_core that checks the list
of valid plugins to see if any of them export a pre/post processing
function for the current command. This logic is applied only to the
plugins and allows plugin authors to hook into rebar's execution by
using a naming convention that matches the one used for scripting hooks.
Example:
```erlang
-module(my_rebar_plugin).
-export([pre_compile/2]).
pre_compile(Config, AppFile) ->
rebar_log:log(debug, "PRECOMPILE: ~p:~p~n",
[AppFile, Config]),
ok.
```
