Replace string arrays with const char * and allocated space (part 2)
This commit replaces fixed-string buffers in PROGRAMMER, AVRPART and AVRMEM
that are dealt with by the parser and grammar. Now, string assignments are
always to const char *, ie, these are read-only strings with arbitrary
length.

config_gram.y now only needs to consider one type of string assignment.

This commit also

  - Replaces the simple linear-search cache_string() function with faster
    hashed cache_string(). Either way, the returned value is likely to be
    shared, so should never be free()'d.

  - Duplicates hvupdi_support list in pgm_dup() and frees it in pgm_free()

  - Adds const qualifier to some function args in avrpart.c and pgm.c

  - Hardens some functions against being called with NULL pointers

  - Ensures _new() and _dup() functions for parts, programmers and memory
    return a suitable memory. Out of memory triggers exit in one of three
    functions, cfg_malloc(), cfg_realloc() and cfg_strdup(); there is
    rarely anything useful that AVRDUDE or, for that matter, any
    application compiled against libavrdude can do once you run out of
    memory as AVRDUDE/libavrdude rely heavily on allocation of memory.

Harden string processing during parsing in lexer.l, config_gram.y and otherwise
- Replace strdup(s) with cfg_strdup(funname, s) that exits on out of mem
 - Replace malloc(n) with cfg_malloc(funname, n) that exits on out of mem
 - Change multiline string scanning in lexer.l to avoid core dump
 - Remove global variables string_buf and string_bug_ptr
 - Ensure reading strings unescapes strings C-Style
 - Ensure writing strings escapes strings C-Style again

Commit looks longer than needed as unescape() and auxiliary functions needed
to be moved from term.c (not in libavrdude) to config.c (in libavrdude).

Switch from strerror_r() to strerror() in update.c for portability 2022-08-06 00:20:43 +01:00

Implement a dry run for -U updates before opening the programmer
This commit checks -U update requests for
  - Typos in memory names
  - Whether the files can be written or read
  - Automatic format detection if necessary

before opening the programmer. This to reduce the chances of the
programming failing midway through.

Minor additional changes:
  - Give strerror() system info when files are not read/writeable
  - Lift the auto detection message from MSG_INFO to MSG_NOTICE
  - Provide fileio_fmt_autodetect() in the AVRDUDE library
  - Rename fmtstr() in the AVRDUDE library to fileio_fmtstr() to
    avoid name clashes when an application links with it

Example:

$ avrdude -U - -U typo:r:.:h -U eeprom:w:testin:r -p ... -c ...
avrdude: can't auto detect file format for stdin/out, specify explicitly
avrdude: unknown memory type typo
avrdude: file . is not writeable (not a regular or character file?)
avrdude: file testin is not readable. No such file or directory

Stefan Rueger 3412196cd9 Weaken -U memory type check and move after config file parsing in main.c
The check for typos in -U memory names against a list of known memory names
now happens after the config files have been read, so newly declared memory
names can be considered. This commit also weakens the check against existence
of a known memory: it is now sufficent for a name to pass when it could be
the initial string of any known memory of any part. Any -U memory that cannot
possibly be matched up with a known memory is considered a typo and leads to
an exit before the programmer is opened.

This to protect users from typos that leave a device partially programmed.

When every -U memory name might be matching one of the known memories, the
programming is attempted. If the part to be programmed turns out not to have
a particular -U memory, AVRDUDE warns the user and skips this -U update.

This to support unifying interfaces that call AVRDUDE with potentially more
memories than the actual part has (eg, efuse on ATmega8).

Stefan Rueger 02027ab766 Enable stdin verification and display correct number of bytes written/verified
Counting the number of bytes written to a memory and/or verified is not
trivial owing to potential holes in the input file and to potential trailing
0xff bytes in flash memory that are not written per default (but see -A). The
new function memstats(), which is best called just after an input file has
been read into mem->buf/mem->tags, computes the right number of bytes written
and allows easy computation of the number of bytes verified.

This commit also changes the strategy for the default verification after
writing to a chip memory, so that the input file only needs reading once thus
enabling successful verification of stdin input files.

Other, minor changes:
 - Improving the grammar of AVRDUDE output, eg, 1 byte written instead of
   1 bytes written
 - Better description of the input file structure in terms of its sections,
   the interval it spans, the number  of pages, the number of padding bytes
   in pages, and the number of actually cut off trailing 0xff bytes for flash
 - Printing <stdin> or <stdout> instead of - in the -U routines
 - Option -V no longer needs to be specified before option -U in order to work

As an aside this commit also provides useful helper functions for printing
plural(), inname(), outname() and interval() all of which return strings fit
for printing.

Joerg Wunsch cc93bd2c83 Move the error handling for invalid file formats to fileio.c
The checks used to be in update.c, but as they are related to
the intended file operation, they are better placed in fileio.c.

The checks affected are to refuse 'm' on output (file write),
and 'd', 'h', 'o', and 'b' formats on input (file read).

Joerg Wunsch 26f431c944 Handle invalid -U file format specifiers for input
The file format specifiers 'h', 'd', 'o', and 'b' are only valid for
outputting data. Reject them with a proper error message when
attempting to use them for input.

Stefan Rueger 79921e52dc Provide file format I: Intel HEX with comments that ignores checksum errors
The new file type I is essentially Intel HEX that, on download, inserts
comments next to data records with the resolved effective address and an
ASCII dump of that same record. On upload the `I` format is permissive
with respect to check sum errors, eg, after manipulated an Intel HEX file
for debugging.
