Use pkg-config to find cppunit, libxml2 and expat. All those libraries
provide pkg-config files, and in all of those cases the pkg-config macro
is superior to the custom macros used currently.
The advantages of pkg-config files include:
- Explicit static linking support via --static. Currently, e.g.
'xml2-config --libs' prints all libraries needed for static linking when
doing dynamic linking unnecessary, resulting in unnecessary direct deps.
- Better cross-build support. You don't have to build the additional
*-config tools for target.
- Better multilib support. Per-ABI pkgconfig directories are commonly
supported while packages usually fail to look for per-CHOST *-config
variants.
- Better override support. The current macros allow little to no
result overrides, the pkg-config macros let you pass FOO_CFLAGS
and FOO_LIBS manually.
- Cleaner version checks. The code used in libxml.m4 is really creepy.
We moved @CPPUNIT_LIBS@ to later position. This is because in my
development environment, it adds linker search directory which
contains system default openssl, while I'd like to use my custom
openssl installation. This fix is not universal, since other
libraries can do the same thing. It is a bit hard to fix this
properly because we mix -L and -l in a same variable.
Saved sessions may very large, as in hundreds and even thousands of
megabyte when dealing with large queues.
Add support to save and reload sessions to gzipped files, when libz is
available.
The session serializer will output gzipped contents when the file ends
with .gz, while the input file reader (UriListParser) will accept
whatever is thrown at it.
This change replaces the current 64 bit sequential GID with 64 bits
random bytes GID in an attempt to support persistent GID. Internally,
the GID is stored as uint64_t. For human representation and RPC
interface, GID is represented as 16 bytes hex string. For console
readout, 16 bytes are too long, so it is abbreviated to first 6 bytes.
When querying GID in RPC calls, user can speicfy the prefix of GID as
long as the prefix is shared by more than 1 GID entries.
This option enables disk cache. If SIZE is 0, the disk cache is
disabled. This feature caches the downloaded data in memory, which
grows to at most SIZE bytes. The cache storage is created for aria2
instance and shared by all downloads. The one advantage of the disk
cache is reduce the disk seek time because the data is written in
larger unit and it is reordered by the offset of the file. If the
underlying file is heavily fragmented it is not the case.
If the number of pieces gets bigger, the length of Bitfield message
payload exceeds the initial buffer capacity of PeerConnection, which
is MAX_PAYLOAD_LEN. We expand buffer as necessary so that
PeerConnection can receive the Bitfield message.
The previous implementation constructs proxy URI in OptionHandler but
it cannot handle with the situation when user, password and proxy URI
is given various order. Now we just set rules: username set in
--*-proxy-user overrides username in --*-proxy option, no matter in
any order username, password and proxy URI are parsed. Likewise,
password set in --*--proxy-passwd overrides password in --*-proxy
option.
We added 2 macros A2_TEST_DIR and A2_TEST_OUT_DIR to pass tests in
`make distcheck`. A2_TEST_DIR refers to test directory. All output
files by unit tests are now created under A2_TEST_OUT_DIR directory.
