* Improve documentation for malloc etc. (BZ#27719)Paul Eggert2021-04-131-16/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cover key corner cases (e.g., whether errno is set) that are well settled in glibc, fix some examples to avoid integer overflow, and update some other dated examples (code needed for K&R C, e.g.). * manual/charset.texi (Non-reentrant String Conversion): * manual/filesys.texi (Symbolic Links): * manual/memory.texi (Allocating Cleared Space): * manual/socket.texi (Host Names): * manual/string.texi (Concatenating Strings): * manual/users.texi (Setting Groups): Use reallocarray instead of realloc, to avoid integer overflow issues. * manual/filesys.texi (Scanning Directory Content): * manual/memory.texi (The GNU Allocator, Hooks for Malloc): * manual/tunables.texi: Use code font for 'malloc' instead of roman font. (Symbolic Links): Don't assume readlink return value fits in 'int'. * manual/memory.texi (Memory Allocation and C, Basic Allocation) (Malloc Examples, Alloca Example): * manual/stdio.texi (Formatted Output Functions): * manual/string.texi (Concatenating Strings, Collation Functions): Omit pointer casts that are needed only in ancient K&R C. * manual/memory.texi (Basic Allocation): Say that malloc sets errno on failure. Say "convert" rather than "cast", since casts are no longer needed. * manual/memory.texi (Basic Allocation): * manual/string.texi (Concatenating Strings): In examples, use C99 declarations after statements for brevity. * manual/memory.texi (Malloc Examples): Add portability notes for malloc (0), errno setting, and PTRDIFF_MAX. (Changing Block Size): Say that realloc (p, 0) acts like (p ? (free (p), NULL) : malloc (0)). Add xreallocarray example, since other examples can use it. Add portability notes for realloc (0, 0), realloc (p, 0), PTRDIFF_MAX, and improve notes for reallocating to the same size. (Allocating Cleared Space): Reword now-confusing discussion about replacement, and xref "Replacing malloc". * manual/stdio.texi (Formatted Output Functions): Don't assume message size fits in 'int'. * manual/string.texi (Concatenating Strings): Fix undefined behavior involving arithmetic on a freed pointer.
* manual: clarify that scanf %n supports type modifiersAlyssa Ross2021-03-301-5/+6
| | | | | | | | | | My initial reading of the %n documentation was that it didn't support type conversions, because it only mentioned int*. Corresponding man-pages patch: https://lore.kernel.org/linux-man/20210328215509.31666-1-hi@alyssa.is/ Reviewed-by: Arjun Shankar <arjun@redhat.com>

* manual: Fix Texinfo warnings about improper node names.Rical Jasan2018-02-091-4/+4
| | | | | | | | | | | | | | | A number of cross-references to the GCC info manual cause Texinfo warnings; e.g.: ./creature.texi:11: warning: @xref node name should not contain `.' This is due to "gcc.info" being used in the INFO-FILE-NAME (fourth) argument. Changing it to "gcc" removes these warnings. (Manually confirmed equivalent behaviour for make info, html, and pdf.) * manual/creature.texi: Convert references to gcc.info to gcc. * manual/stdio.texi: Likewise. * manual/string.texi: Likewise.
* manual: Replace summary.awk with summary.pl.Rical Jasan2017-06-151-330/+165
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Summary is now generated from @standards, and syntax-checking is performed. If invalid @standards syntax is detected, summary.pl will fail, reporting all errors. Failure and error reporting is disabled for now, however, since much of the manual is still incomplete wrt. header and standards annotations. Note that the sorting order of the Summary has changed; summary.pl respects the locale, like summary.awk did, but the use of LC_ALL=C is introduced in the Makefile. Other notable deviations are improved detection of the annotated elements' names, which are used for sorting, and improved detection of the @node used to reference into the manual. The most noticeable difference in the rendered Summary is that entries may now contain multiple lines, one for each header and standard combination. summary.pl accepts a `--help' option, which details the expected syntax of @standards. If errors are reported, the user is directed to this feature for further information. * manual/Makefile: Generate summary.texi with summary.pl. Force use of the C locale. Update Perl dependency comment. * manual/header.texi: Update reference to summary.awk. * manual/macros.texi: Refer authors to `summary.pl --help'. * manual/summary.awk: Remove file. * manual/summary.pl: New file.

* libio: Avoid dup already opened file descriptor [BZ#21393]Adhemerval Zanella2017-05-221-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As described in BZ#21398 (close as dup of 21393) report current freopen implementation fails when one tries to freopen STDIN_FILENO, STDOUT_FILENO, or STDERR_FILENO. Although on bug report the discussion leads to argue if a close followed by a freopen on the standard file is a valid operation, the underlying issue is not really the check for dup3 returned value, but rather calling it if the returned file descriptor is equal as the input one. So for a quality of implementation this patch avoid calling dup3 for the aforementioned case. It also adds a dup3 error case check for the two possible failures, with one being Linux only: EINTR and EBUSY. The EBUSY issue is better explained on this stackoverflow thread [1], but in a short it is due the internal Linux implementation which allows a race condition window for dup2 due the logic dissociation of file descriptor allocation and actual VFS 'install' operation. For both outliers failures all allocated memory is freed and a NULL FILE* is returned. With this patch the example on BZ#21398 is now actually possible (I used as the testcase for the bug report). Checked on x86_64-linux-gnu. [BZ #21393] * libio/freopen.c (freopen): Avoid dup already opened file descriptor and add a check for dup3 failure. * libio/freopen64.c (freopen64): Likewise. * libio/tst-freopen.c (do_test): Rename to do_test_basic and use libsupport.

* manual: Convert @tables of variables to @vtables.Rical Jasan2016-12-211-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Texinfo @vindex commands add entries to the Variable and Constant Macro Index. Similarly, @items in @vtables are automatically indexed. A number of @tables exist where all @items are @vindexed or all @items are variables, but not indexed, suggesting an optimization by converting such @tables to @vtables and dropping the @vindex. Using a @vtable provides a context for processing @items whereby it can be known the @items should have header and standards annotations. This commit converts @tables of such @items to @vtables in order to establish a framework for automated processing. A pleasant consequence of these changes is that @items previously lacking a @vindex are present in the Variable and Constant Macro Index now. @vindex entries previously detected by summary.awk will still be detected as @items with appropriate annotations. The @vtable of the NSS databases is converted to a @table because 1) those @items are not variables (and will no longer appear in the Variable and Constant Macro Index) and 2) they do not need header and standards annotations, so the incorrect context is fixed. * manual/nss.texi: Change incorrect @vtable to @table. * manual/arith.texi: Convert @tables of variables to @vtables and remove unnecessary indexing. * manual/filesys.texi: Likewise. * manual/llio.texi: Likewise. * manual/memory.texi: Likewise. * manual/process.texi: Likewise. * manual/resource.texi: Likewise. * manual/search.texi: Likewise. * manual/signal.texi: Likewise. * manual/socket.texi: Likewise. * manual/stdio.texi: Likewise. * manual/sysinfo.texi: Likewise. * manual/syslog.texi: Likewise. * manual/terminal.texi: Likewise. * manual/time.texi: Likewise. * manual/users.texi: Likewise.

* manual: clarify buffer behavior in getline [BZ #5666]David Svoboda2014-04-031-1/+2
| | | | | | | | | | | If the user has requested automatic buffer creation, getline may create it and not free things when an error occurs. That means the user is always responsible for calling free() regardless of the return value. The current documentation does not explicitly cover this which leaves it slightly ambiguous to the reader.
