* Don't require test wrappers to preserve environment variables, use more ↵Joseph Myers2014-06-0645-248/+419
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | consistent environment. One wart in the original support for test wrappers for cross testing, as noted in <https://sourceware.org/ml/libc-alpha/2012-10/msg00722.html>, is the requirement for test wrappers to pass a poorly-defined set of environment variables from the build system to the system running the glibc under test. Although some variables are passed explicitly via $(test-wrapper-env), including LD_* variables that simply can't be passed implicitly because of the side effects they'd have on the build system's dynamic linker, others are passed implicitly, including variables such as GCONV_PATH and LOCPATH that could potentially affect the build system's libc (so effectively relying on any such effects not breaking the wrappers). In addition, the code in cross-test-ssh.sh for preserving environment variables is fragile (it depends on how bash formats a list of exported variables, and could well break for multi-line variable definitions where the contents contain things looking like other variable definitions). This patch moves to explicitly passing environment variables via $(test-wrapper-env). Makefile variables that previously used $(test-wrapper) are split up into -before-env and -after-env parts that can be passed separately to the various .sh files used in testing, so those files can then insert environment settings between the two parts. The common default environment settings in make-test-out are made into a separate makefile variable that can also be passed to scripts, rather than many scripts duplicating those settings (for testing an installed glibc, it is desirable to have the GCONV_PATH setting on just one place, so just that one place needs to support it pointing to an installed sysroot instead of the build tree). The default settings are included in the variables such as $(test-program-prefix), so that if tests do not need any non-default settings they can continue to use single variables rather than the split-up variables. Although this patch cleans up LC_ALL=C settings (that being part of the common defaults), various LANG=C and LANGUAGE=C settings remain. Those are generally unnecessary and I propose a subsequent cleanup to remove them. LC_ALL takes precedence over LANG, and while LANGUAGE takes precedence over LC_ALL, it only does so for settings other than LC_ALL=C. So LC_ALL=C on its own is sufficient to ensure the C locale, and anything that gets LC_ALL=C does not need the other settings. While preparing this patch I noticed some tests with .sh files that appeared to do nothing beyond what the generic makefile support for tests can do (localedata/tst-wctype.sh - the makefiles support -ENV variables and .input files - and localedata/tst-mbswcs.sh - just runs five tests that could be run individually from the makefile). So I propose another subsequent cleanup to move those to using the generic support instead of special .sh files.

* Include LOCPATH in default test environment.Joseph Myers2014-06-0414-155/+158
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tests run using the default $(make-test-out) automatically get GCONV_PATH and LC_ALL set, whether or not those environment variables are actually needed for the individual test. However, they do not get LOCPATH set, meaning that a large number of tests have -ENV settings just to set LOCPATH. This patch moves LOCPATH into the default environment used for all tests, on the principle that like GCONV_PATH any settings needed to use files associated with the newly built library, rather than any old installed files, are appropriate to use by default. A further motivation is that various tests using .sh files also set some combination of LC_ALL, GCONV_PATH and LOCPATH. Preferably .sh files should also use the default environment with any additions required for the individual test. Now, it was suggested in <https://sourceware.org/ml/libc-alpha/2014-05/msg00715.html> that various Makefile variables used in testing should be derived by composing the -before-env and -after-env variables used when explicit environment settings are required. With such a change, it's also natural for those variables to include the default settings (via some intermediate makefile variable also used in make-test-out). Because some .sh files only set variables that correspond to the default settings, or a subset thereof, and this applies to more of the .sh files once LOCPATH is in the default settings, doing so reduces the size of a revised version of <https://sourceware.org/ml/libc-alpha/2014-05/msg00596.html>: scripts only needing the (expanded) default settings will not need to receive the separate -before-env and -after-env variables, only the single variable they do at present. So moving LOCPATH into the default settings can reduce churn caused by subsequent patches.

* ARM: Fix handling of concurrent TLS descriptor resolutionWill Newton2014-05-273-20/+19
| | | | | | | | | | | | | | | | | | | | The current code for handling concurrent resolution says that the ABI for _dl_tlsdesc_resolve_hold is the same as that of _dl_tlsdesc_lazy_resolver. However _dl_tlsdesc_resolve_hold is called from the trampoline directly rather than the lazy resolver stub so, for example, r2 has not been pushed so does not needed to be restored. This fixes an intermittent failure in nptl/tst-tls3 when building glibc for arm-linux-gnueabihf with -mtls-dialect=gnu2. ChangeLog: 2014-05-27 Will Newton <will.newton@linaro.org> [BZ #16990] * sysdeps/arm/dl-tlsdesc.S (_dl_tlsdesc_resolve_hold): Save and restore r2 rather than just restoring.
* Fix offset computation for append+ mode on switching from read (BZ #16724)Siddhesh Poyarekar2014-05-276-10/+207
| | | | | | | | | | | | | | | | | The offset computation in write mode uses the fact that _IO_read_end is kept in sync with the external file offset. This however is not true when O_APPEND is in effect since switching to write mode ought to send the external file offset to the end of file without making the necessary adjustment to _IO_read_end. Hence in append mode, offset computation when writing should only consider the effect of unflushed writes, i.e. from _IO_write_base to _IO_write_ptr. The wiki has a detailed document that describes the rationale for offsets returned by ftell in various conditions: https://sourceware.org/glibc/wiki/File%20offsets%20in%20a%20stdio%20stream%20and%20ftell
