package/bash: indicate getcwd is malloc-supported

2015-09-04T14:45:42+00:00

When Bash attempts to find the current working directory, it uses a C library call `getcwd` to resolve it. When cross-compiling, the configuration process cannot determine if the target system's C library can support an "unfixed" path length. Therefore, Bash will fallback to a size of `PATH_MAX` for determining the current working directory. When using OverlayFS (and possible other file systems), this becomes an issue since file paths can commonly exceed standard `PATH_MAX` length. This typically results in the following error appearing: error retrieving current directory: [...] Common C library `getcwd` calls can default to a higher limit (usually the system's page size). The current configurable C libraries (as of at least 2015.08) support a zero (0) size buffer length. Most use the system's page size; musl, being an exception, which defaults to `PATH_MAX` (as Bash was doing). Since these C libraries support allocating buffer space with a zero (0) provided size, the following configuration change allows Bash to support getting a larger-length'ed working directory on target's that support it.

Rename BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS

2014-12-11T21:48:13+00:00

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed from "prefer static libraries when possible" to "use only static libraries". The former semantic didn't make much sense, since the user had absolutely no control/idea of which package would use static libraries, and which packages would not. Therefore, for quite some time, we have been starting to enforce that BR2_PREFER_STATIC_LIB should really build everything with static libraries. As a consequence, this patch renames BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS, and adjust the Config.in option accordingly. This also helps preparing the addition of other options to select shared, shared+static or just static. Note that we have verified that this commit can be reproduced by simply doing a global rename of BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

bash: fix linking for static builds with uClibc toolchains

2014-10-25T10:45:08+00:00

bash fails to link for static builds with uClibc toolchains due to getenv redefinitions. This is caused because bash is unable to check if getenv is already defined when cross-compiling, so it defaults to 'yes': configure:14438: WARNING: cannot check getenv redefinition if cross compiling -- defaulting to yes We can avoid this redefinition by passing bash_cv_getenv_redef=no to the configure script.

system: add option to choose what /bin/sh points to

2014-10-12T13:51:38+00:00

Not all our shells do install a pointer to /bin/sh. Besides, between those that do and multiple ones are enabled, the last one to install wins the the symlink. Add a new config choice in the system sub-menu that allows the user to explicitly select the shell to provide /bin/sh. If busybox is not enabled, default to using dash, a POSIX shell. Remove the symlink creation from bash.mk at the same time. Note: for every shell, we select them, except busybox, on which we depend, on the assumption that we do not want to force busybox in case the user decided not to enable it.
