debug of ipdl demo(2)

2017.9.27 wednesday

afternoon

the problems now are:

1.don't know how to generate a whole directory file of executable binary with cmake?

2.don't know how these header and cpp worked together  to work things out.

some other question:

is it possible to use cmake to fix the first problem?

if not ,what would be okay?

so ,what is the best thing i should do to solve this problem of demo working.

all day learn about makefile and try to use it to compile my project.

2017.9.28 Thursday

morning,

learn about makefile,

now try to use it in project of ipdl compile .

--------------------------------------------------------------------------------------------------------------------

2017.9.29 friday

the headers can't be found in directory as a link.

then ,use ln -s source dist

to link them .

change the headers like a fool.

but ,i get tired to debug this by change their header or its directory.

plan to change a method to build it in build .while the document is too little to make a demo.

--------------------------------------------------------------------------------------------------------------------

2017.9.30 Saturday

what should be done now to finish this demo?

another method to build in system ,read the low level document and try the build .use make ipc/ipdl get the files .maybe they should live in the object directory.

i find a useful file in /B2G-5.1.1/gecko/ipc/ipdl/test/cxx:README.TXT

  1  To add a new IPDL C++ unit test, you need to create (at least) the  2 following files (for a test "TestFoo"):  3   4   - PTestFoo.ipdl, specifying the top-level protocol used for the test  5   6   - TestFoo.h, declaring the top-level parent/child actors used for  7     the test  8   9   - TestFoo.cpp, defining the top-level actors 10  11   - (make sure all are in the namespace mozilla::_ipdltest) 12  13 Next 14  15   - add PTestFoo.ipdl to ipdl.mk 16  17   - append TestFoo to the variable IPDLTESTS in Makefile.in 18  19 You must define three methods in your |TestFooParent| class: 20  21   - static methods |bool RunTestInProcesses()| and 22     |bool RunTestInThreads()|.  These methods control whether 23     to execute the test using actors in separate processes and 24     threads respectively.  Generally, both should return true. 25  26   - an instance method |void Main()|.  The test harness wil first 27     initialize the processes or threads, create and open both actors, 28     and then kick off the test using |Main()|.  Make sure you define 29     it. 30  31 If your test passes its criteria, please call 32 |MOZ_IPDL_TESTPASS("msg")| and "exit gracefully". 33  34 If your tests fails, please call |MOZ_IPDL_TESTFAIL("msg")| and "exit 35 ungracefully", preferably by abort()ing. 36  37  38 If all goes well, running 39  40   make -C $OBJDIR/ipc/ipdl/test/cxx 41  42 will update the file IPDLUnitTests.cpp (the test launcher), and your 43 new code will be built automatically. 44  45  46 You can launch your new test by invoking one of 47  48   make -C $OBJDIR/ipc/ipdl/test/cxx check-proc     (test process-based tests) 49   make -C $OBJDIR/ipc/ipdl/test/cxx check-threads  (test thread-based tests) 50   make -C $OBJDIR/ipc/ipdl/test/cxx check          (tests both) 51  52 If you want to launch only your test, run 53  54   cd $OBJDIR/dist/bin 55   ./run-mozilla.sh ./ipdlunittest TestFoo          (test in two processes, if appl.) 56   ./run-mozilla.sh ./ipdlunittest thread:TestFoo   (test in two threads, if appl.) 57  58  59 For a bare-bones example of adding a test, take a look at 60 PTestSanity.ipdl, TestSanity.h, TestSanity.cpp, and how "TestSanity" 61 is included in ipdl.mk and Makefile.in.

this gives some information about ipdl.

if change the Testfoo to 'Testopens'

1.3 files :

PTestOpens.ipdl

TestOpens.h

TestOpens.cpp

2.(make sure all are in the namespace mozilla::_ipdltest)    ???

3.add PTestFoo.ipdl(here,change as Testopen.ipdl) to ipdl.mk

i don't know where is ipdl.mk ,cannot find out it ,so just copy from internet,

https://searchcode.com/codesearch/view/883109/

IPDLSRCS =          \  PWyciwygChannel.ipdl \  $(NULL)

but i found that there is a moz.build and they add a lot of ipdl files in it.

4.append TestFoo to the variable IPDLTESTS in Makefile.in

5.You must define three methods in your |TestFooParent| class:

- static methods |bool RunTestInProcesses()| and     |bool RunTestInThreads()|.

- an instance method |void Main()|.

6.call

|MOZ_IPDL_TESTPASS("msg")| and "exit gracefully".

or ,

|MOZ_IPDL_TESTFAIL("msg")| and "exit ungracefully"

7.if all goes well,

make -C $OBJDIR/ipc/ipdl/test/cxx

8.

If you want to launch only your test, run

cd $OBJDIR/dist/bin   

./run-mozilla.sh ./ipdlunittest TestFoo          (test in two processes, if appl.)  

./run-mozilla.sh ./ipdlunittest thread:TestFoo   (test in two threads, if appl.) 

just have a try.

so where is parent and child ,where can i add the complement codes of hello world?

and is there anything should be done  in object dictionary ?
