CDE has relied upon catgets() implementations following a relaxed
interpretation of the XPG internationalization standard that ignored
-1, the standard error value returned by catopen, as the catalog
argument. However, this same behavior causes segmentation faults with
the musl C library.
This patch:
- Centralizes (with the exception of ToolTalk) all calls to catopen(),
catgets(), and catclose() through MsgCat within the DtSvc library.
- Prevents calls to catgets() and catclose() that rely upon
undefined behavior.
- Eliminates a number of bespoke catgets() wrappers, including multiple
redundant caching implementations designed to work around a design
peculiarity in HP/UX.
- Eases building CDE without XPG internationalization support by providing
the appropriate macros.
The localized/utils/merge utility used hardcoded temporary filenames
to do its thing. This prevented any Makefiles that called merge from
enabling parallel builds in order avoid the file collisions that would
result.
Now we:
- use filenames that embed the PID in them, making them unique
per-process
- place them in /tmp, rather than the current directory
As a result, we can now re-enable parallel builds for localized
app-defaults, config, and types.
According to the spec, blank lines in message catalogs or lines
beginning with '$ ' are valid comments.
However, there were many cases where lines in the message catalogs
contained just a single '$', without the required space after it.
Under linux, this caused 126766 error lines (in my builds) of the
form:
... unknown directive `': line ignored
This also causes gencat to exit with a non-0 exit code. Even though
gencat says it ignores the line, it really doesn't.
An early porting change to programs/localized/util/merge.c was made to
ignore this return value on linux. This hack has now been removed.
Build logs are a lot smaller and cleaner now.
