* cmSystemTools: Avoid excess entropy consumption by RandomSeed (#15976)Cristian Rodríguez2016-02-191-2/+4
| | | | Read `/dev/urandom` without buffering to avoid taking more than we need.
* cmSystemTools: Remove unused include <fcntl.h>Brad King2016-02-191-2/+1
| | | | | We do not seem to need this header anymore, and including it on AIX causes `#define open open64` which breaks `std::ifstream::open` calls.
* cmSystemTools: Teach RunSingleCommand to merge child pipes when possibleBrad King2016-01-191-23/+21
| | | | | | | | | Audit the code to make sure there are no callers that use OUTPUT_MERGE with separate capture strings. Then change RunSingleCommand to implement output merging by giving the child process a single pipe for both its stdout and stderr descriptors. This will more cleanly merge the content on atomic write boundaries in the child instead of on arbitrary buffering boundaries in the parent.
* cmSystemTools: Simplify RunSingleCommand output string constructionBrad King2016-01-191-13/+4
| | | | | | Assign to the result strings instead setting to empty and appending. The old approach was left from when we directly buffered output in the strings.
* cmSystemTools: Drop redundant condition in RunSingleCommandBrad King2016-01-191-9/+7
| | | | | The output processing loop is already guarded by a condition so we do not need to repeat the condition inside the loop.
* install: Do not remove compiler-defined RPATH entriesLior Goldberg2016-01-151-1/+26
| | | | | | | | | | | | | | | | | | Some compilers may add their own RPATH entries when invoking the linker. For example, a GCC installation may contain the following definition in the specs file: *link_libgcc: %D -rpath <<some specific rpath in which libstdc++.so can be found>> In this case binaries may contain RPATH entries that CMake did not add. When we update the RPATH on installation we must preserve these entries even if CMake thinks the INSTALL_RPATH value should be empty. Fix this by always using file(RPATH_CHANGE) and teach it to behave as file(RPATH_REMOVE) if the actual RPATH in the file is empty after replacing the build-tree RPATH with the install-tree RPATH. This will preserve any compiler-added RPATH value instead of removing it.

| | | | | | | | | The changes in commit 47b060ae (CPackDeb: allow empty directories in component packages, 2015-09-21), commit b58de9fe (CPack: allow packaging of empty directories, 2015-09-21), and commit b761e90d (CPack: remove accidental changes, 2015-09-22) regressed packaging of CMake itself. Revert the changes until they can be revised and rebased on other changes that make additional fixes.

| | | | | This executable comes with CMake so just compute its location in cmSystemTools instead of storing it in compiler information modules.
* cmSystemTools: Fix TrimWhitespace for non-ascii strings (#15735)Brad King2015-09-101-2/+2
| | | | | | | | Since commit v2.8.11~59^2 (cmSystemTools: Generalize TrimWhitespace to all whitespace, 2013-03-27) we incorrectly use `c <= ' '` to determine if `c` is a whitespace character. With a signed `char` type UTF-8 encoded strings may be truncated because values above 0x7f appear negative and therefore less than 0x20. Use `isspace(c)` instead.
* cmSystemTools: Factor out a cm_isspace helperBrad King2015-09-101-1/+6
| | | | | | Extract the logic added by commit v3.1.0-rc1~386^2 (Encoding: Fix debug asserts ... with non-ascii chars, 2014-06-16) into a helper function so we can re-use it.

| * cmSystemTools: Use CreateFileW explicitly to pass wchar_t pathBrad King2015-08-311-7/+8
| | | | | | | | | | | | | | The call to CreateFile added by commit ac0bb433 (VS: Windows Store/Phone package cert thumbprint, 2015-08-21) passes a wide character path explicitly so we should call CreateFileW directly. Otherwise it does not build without -DUNICODE (e.g. in bootstrap on MSYS).

|\ \ | | | | | | | | | | | | bfb9d34f Makefile: Print color escapes only when necessary
| * | Makefile: Print color escapes only when necessaryBrad King2015-08-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Teach cmSystemTools::MakefileColorEcho to use the color printing API only when we actually have a color to print. This avoids printing escape sequences that do not change the text attributes. Since commit v3.3.0-rc1~480^2~4 (Makefile: Fix output during parallel builds, 2015-02-05) we always use this code path to print progress and rule messages even when color is disabled (e.g. in a try_compile). It is important to avoid printing escapes when there is no color because on MSYS we have no isatty and so assume that vt100 escapes are supported, but we do not want to print them when capturing try_compile output. If we capture the vt100 escapes in try_compile output, they contain unbalanced square brackets. This causes CMakeParseImplicitLinkInfo to fail to separate lines in a ;-list and therefore fail to extract information from the link line. Then mixed-language linking breaks.

* cmSystemTools: Fix IsPathToFramework implementation (#15535)Brad King2015-04-271-9/+2
| | | | | | | | Use more reliable logic to detect if a path ends in ".framework". The old logic added by commit v2.4.0~791 (add better support for framework linking, 2005-12-26) did not account for paths not ending in it at all. With a 9-character path the logic and "npos == -1" happens to make the old check pass.
* cmSystemTools: Teach RunSingleCommand to separate stdout and stderrBrad King2015-04-201-19/+44
| | | | | | | Extend the RunSingleCommand signature to capture stdout and stderr separately. Allow both to be captured to the same std::string to preserve existing behavior. Update all call sites to do this so that this refactoring does not introduce functional changes.
* cmake: Teach "-E tar" command a "--format=" optionNils Gladitz2015-04-101-2/+5

* cmAlgorithms: Add cmWrap.Stephen Kelly2015-02-201-1/+1
| | | | | | | | | | | | | Port some existing cmJoin to use it. cmJoin is cumbersome to use in cases where the objective is to somehow 'quote' each item and then join it with a separator. In that case, the joiner string is harder to read and reason about. cmWrap aims to solve that. Provide an overload taking char wrappers to simplify the case of surrounding every element in quotes without needing to escape the quote character.

| * Add setlocale() calls around use of libarchive APIs (#14934, #15377)Brad King2015-02-061-0/+3
| | | | | | | | | | | | | | | | | | | | The libarchive APIs use nl_langinfo(CODESET) for iconv so they need the locale to be set for LC_CTYPE. However, the rest of CMake does not define any behavior for non-ASCII character classification/conversion so we do not want to setlocale() globally. Add a RAII class to save, set, and restore the locale around calls to libarchive APIs. Inspired-by: Clinton Stimpson <clinton@elemtech.com>
