Commit c3781efb (Support Git upstream branch rewrites, 2010-06-08)
assumed that ".git/FETCH_HEAD" exists inside the source tree. Fix the
implementation to handle a work tree using a ".git file" to link to its
repository. Use "git rev-parse --git-dir" to locate the real .git dir.
If .git/FETCH_HEAD provides no merge candidate do not attempt to update.
Also log FETCH_HEAD lines as we parse them since they are essentially
output from the git fetch command.
38c762c Merge 'remove-CTestTest3' into ctest-file-checksum
46df0b4 Activate retry code on any curl submit failure.
8705497 Checksum test should use CMAKE_TESTS_CDASH_SERVER
d0d1cdd Mock checksum failure output for old CDash versions
af5ef0c Testing for CTest checksum
86e81b5 CTest should resubmit in the checksum failed case
d6b7107 Fix subscript out of range crash
082c87e Cross-platform fixes for checksum/retry code
e525649 Checksums on CTest submit files, and retry timed out submissions.
Previously, we were only going into the retry block
for time out conditions. But a "could not connect"
response, or really any sort of curl failure, is
also a condition where we should retry the submit
if the user has requested a retry.
Fix niggly in ExternalProject that would inadvertently
create a log file of output when a command was explicitly
set to the empty string.
Also, increase the default value for showing context
around build errors to 10 lines, up from 6. Also add
the ability to customize this setting so that users
can put it back to 6 or even lower if they want, or
show more if they want.
Clang is smart enough to recognize that "*(int*)0=0" invokes undefined
behavior, warns, and produces an "undefined instruction". The message
in commit "Avoid Clang optimizer bug in testProcess-[45]" (2010-07-02)
is incorrect; this is not a Clang bug. It really is undefined
behavior. Use "*(int*)1=0" to produce a crash instead.
Clang's optimizer, as of clang version 2.8 (trunk 107463), produces the
undefined instruction 'ud2' for the code "*(int*)0=0" on OS X x86_64.
It causes our crash tests to fail because the child process exits with
an invalid instruction instead of a segmentation fault. Work around the
bug by using "*(int*)1=0" in this case.
Add option KWSYS_TEST_BOGUS_FAILURES that can be set by a containing
project or in the CMake cache to list tests known to fail consistently
on a buggy system.
Commit ff1f8d0b (Fix or cast more integer conversions in cmake) changed
a member type from int to size_t. Update the types of variables
compared to these values to be unsigned also.
Both possible result values need to be convertible to the same type.
Some compilers fail to recognize that they can construct std::string
from the empty string literal, so state it explicitly.
Since commit "Provide unix-sytle command line parsing" (2009-07-13) the
reference to KWSYS_C_HAS_PTRDIFF_T in System.c has been meaningless
because the macro was never passed to the compiler!
Separation by ',' only works in VS 2008 and below and does not work in
the PlayStation3 VS plugin. Separation by ';' works in VS 10 and all
prior versions.
Change types of local variables, or casting, or re-arrange
expressions to get rid of "conversion may alter value" warnings
as seen on recent dashboard submissions from londinium.kitware.
I naively assumed in my previous commit that the Convert call
would correctly convert a relative path file name correctly
relative to the makefile's current output directory. It actually
converts it relative to the process's current working directory.
So it would be different depending on how you launched cmake-gui.
This commit ensures that the generated files are always the same
by starting with a full path to begin with, based on the makefile
GetCurrentOutputDirectory method.
Git's diff-tree format has no '\n'-terminated blank line at the end of
its commit message body block if there are no diff lines. Instead the
message body is terminated by '\0' and there is no diff section. Teach
CTest to parse the format in this case.
This is especially important for the Visual Studio 10
generator and its quirky current working directory
behavior.
Also, emit more information about exactly what files are
out of date when cmakeCheckStampFile returns false.
Commit 02f7cfbc (Need to remove the MAKEFLAGS when cmake starts,
2003-05-13) removed the MAKEFLAGS environment variable when CMake starts
to prevent try_compile() from inheriting "make -i". This is unnecessary
in script mode (cmake -P). Instead remove the variable only when
configuring a project.
