The option --trust-server-names allows to use the file names parsed
from a Metalink/XML file. Without --trust-server-names, the safety
mechanism provides secure and predictable file names.
* NEWS: Mention the use of a safe Metalink destination path
* src/metalink.h: Add declaration of functions get_metalink_basename(),
last_component(), metalink_check_safe_path()
* src/metalink.c: Add directive #include "dosname.h"
* src/metalink.c: Add function get_metalink_basename() to return the
basename of a file name, strip w32's drive letter prefixes
* src/metalink.c (retrieve_from_metalink): Enforce Metalink file name
verification, if the file name is unsafe try its basename
* doc/metalink.txt: Update document. Explain --directory-prefix
The function get_metalink_basename() uses FILE_SYSTEM_PREFIX_LEN to
catch any 'C:D:file' (w32 environment), then it removes each drive
letter prefix, i.e. 'C:' and 'D:'.
Unsafe file names contain an absolute, relative, or home path. Safe
paths can be verified by libmetalink's metalink_check_safe_path().
* NEWS: Mention the effect of --directory-prefix over Metalink
* src/metalink.c (retrieve_from_metalink): Add opt.dir_prefix as
prefix to the metalink:file name mfile->name
* doc/metalink.txt: Update document. Explain --directory-prefix
When --directory-prefix=<prefix> is used, set the top of the retrieval
tree to prefix. The default is . (the current directory). Metalink/XML
and Metalink/HTTP files will be downloaded under prefix.
* NEWS: Mention Metalink's file size verification
* src/metalink.c (retrieve_from_metalink): Add file size computation
* doc/metalink.txt: Update document. Remove resolved bugs
Reject downloaded files when they do not agree with their Metalink/XML
metalink:size: https://tools.ietf.org/html/rfc5854#section-4.2.14
At the moment of writing, Metalink/HTTP headers do not provide a file
size field. This information could be obtained from the Content-Length
header field: https://tools.ietf.org/html/rfc6249#section-7
* NEWS: Mention the effects of --continue over Metalink
* src/metalink.c (retrieve_from_metalink): On download error, resume
output_stream with the next mres->url. Keep fully downloaded files
started with --continue, otherwise rename/remove the file
* testenv/Makefile.am: Add new file
* testenv/Test-metalink-xml-continue.py: New file. Metalink/XML
continue/keep existing files (HTTP 416) with --continue tests
Before this patch, with --continue, existing and/or fully retrieved
files which fail the sanity tests were renamed (--keep-badhash), or
removed.
This patch ensures that --continue doesn't rename/remove existing
and/or fully retrieved files (HTTP 416) which fail the sanity tests.
* NEWS: Mention the Metalink "path/file" name format handling
* src/metalink.c (retrieve_from_metalink): Fix NULL filename, set
filename to the right "path/file" value
* src/metalink.c (retrieve_from_metalink): Fix NULL output_stream, set
output_stream to filename when it is created by retrieve_url()
* src/metalink.c (retrieve_from_metalink): Add RFC5854 comments about
proper metalink:file "path/file" name format handling
* doc/metalink.txt: Update document. Remove resolved bugs
If unique_create() cannot create/open the destination file, filename
and output_stream remain NULL. If fopen() is used instead, filename
always remains NULL. Both functions cannot create "path/file" trees.
Setting filename to the right value is sufficient to prevent SIGSEGV
generating from testing a NULL value. This also allows retrieve_url()
to create a "path/file" tree through opt.output_document.
Reading NULL as output_stream, when it shall not be, leads to wrong
results. For instance, a non-NULL output_stream tells when a stream
was interrupted, reading NULL instead means to assume the contrary.
This patch conforms to the RFC5854 specification:
The Metalink Download Description Format
4.1.2.1. The "name" Attribute
https://tools.ietf.org/html/rfc5854#section-4.1.2.1
* src/url.c [HAVE_ICONV]: Include iconv.h and langinfo.h.
(convert_fname): New function.
[HAVE_ICONV]: Convert file name from remote encoding to local
encoding.
(url_file_name): Call convert_fname.
(filechr_table): Don't consider bytes in 128..159 as control
characters.
* tests/Test-ftp-iri.px: Fix the expected file name to match the
new file-name recoding. State the remote encoding explicitly on
the Wget command line.
* NEWS: Mention the URI recoding when built with libiconv.
* src/ftp.c (getftp): Do not use PORT when PASV fails.
* tests/FTPServer.px: Add pasv_not_supported server flag.
* tests/Makefile.am: Add Test-ftp-pasv-not-supported.px
* tests/Test-ftp-pasv-not-supported.px: New test
Fix IP address exposure when automatically falling back from
passive mode to active mode (using the PORT command). A behavior that
may be used to expose a client's privacy even when using a proxy.
