* Use f_bavail to calculate free spacecaozhiyuan2015-06-261-1/+1
| | | | | | | | | | | | | Failures are seen on devices with Linux 3.10. And they are mainly due to this change: https://lwn.net/Articles/546473/ The blocks reserved in this change is not the same thing as what we think are reserved for common usage of root user. And this part is included in free blocks but not in available blocks. Bug: 22118089 Change-Id: I81c9531703298019a4fc11839f28d2cc8b9df34e (cherry picked from commit 3b4977638f48e59d23d7ea2bb6dde78552c257fb)

* Use more aggressive sync writing to applypatch.Michael Runge2014-10-291-8/+36
| | | | | | | | | | We have seen cases where the boot partition is patched, but upon recovery the partition appears to be corrupted. Open up all patched files/partitions with O_SYNC, and do not ignore the errors from fsync/close operations. Bug: 18170529 Change-Id: I392ad0a321d937c4ad02eaeea9170be384a4744b

|/ / | | | | | | | | | | | | | | Older versions of android supported an ASLR system where binaries were randomly twiddled at OTA install time. Remove support for this; we now use the ASLR support in the linux kernel. Change-Id: I8348eb0d6424692668dc1a00e2416fbef6c158a2
* / fix unnecessarily slow writing of EMMC partitionsDoug Zongker2013-12-201-15/+3
|/ | | | | | | | | | | These were attempts to write partitions "conservatively" in hopes of fixing the problems with writing the radio partition on Nexus 4. They didn't work (a kernel patch was needed), but got left in. They make writing of partitions unnecessarily slow (ie, we really shouldn't need to sync() after every 4kb). Roll back most of them, but leave the verification read-back in. Change-Id: I94badc0979e88816c5aa0485f6316c02be69173c

| * recovery: try to write EMMC partitions more reliablyDoug Zongker2013-07-081-6/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nexus 4 has flash errors that manifest during large writes (eg, of the radio partition). Writes of some blocks seem to be dropped silently, without any errors being returned to the user level. Make two changes to the partition-writing code: - break it up into 1MB writes instead of writing partitions with a single fwrite() call. Pause for 50ms in between every chunk. - read the partition back after writing and verify that we read what we wrote. Drop caches before reading so we (hopefully) are reading off the actual flash and not some cache. Neither of these should be necessary.

* reduce some recovery loggingDoug Zongker2012-10-191-6/+21
| | | | | | | | | | | Make minzip log only a count of files when extracting, not individual filenames. Make patching only chatter about free space if there's not enough and compact the other messages. Only the last 8k of the recovery log gets uploaded; this makes it more likely that we will get all of it. Change-Id: I529cb4947fe2185df82b9da5fae450a7480dcecd
* add bonus data feature to imgdiff/imgpatch/applypatchDoug Zongker2012-08-211-5/+8
| | | | | | | | | | | | | | The bonus data option lets you give an additional blob of uncompressed data to be used when constructing a patch for chunk #1 of an image. The same blob must be available at patch time, and can be passed to the command-line applypatch tool (this feature is not accessible from edify scripts). This will be used to reduce the size of recovery-from-boot patches by storing parts of the recovery ramdisk (the UI images) on the system partition.

* Add mode when open(O_CREAT) is used.Nick Kralevich2012-06-271-2/+2
| | | | | | | | | | When creating a new file using open(..., O_CREAT), it is an error to fail to specify a creation mode. If a mode is not specified, a random stack provided value is used as the "mode". This will become a compile error in a future Android change. Change-Id: I73c1e1a39ca36bf01704b07302af4971d234b5a8

| * remove shadowed variable declarationDoug Zongker2010-08-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | An accidental variable declaration ("int enough_space = ..." instead of "enough_space = " inside a block) shadowing the real one meant we were always using the copy-to-cache path for patching, even when not necessary. Remove it. Enforce an absolute minimum of free space as well, to avoid running into problems patching small files, now that the copy-to-cache path is (inadvertently) well-tested.

* | EMMC support in applypatchDoug Zongker2010-07-081-102/+175
|/ | | | | | | | Let applypatch read and write EMMC partitions as well as MTD ones. This enables incremental updates that include boot image changes, as well as OTA of new recovery partitions. Change-Id: I3766b9e77c639769ddf693b675da51d57f6e6b1d
* refactor applypatch and friendsDoug Zongker2010-02-231-722/+637
| | | | | | | | | | | | | | | | | | | Change the applypatch function to take meaningful arguments instead of argc and argv. Move all the parsing of arguments into main.c (for the standalone binary) and into install.c (for the updater function). applypatch() takes patches as Value objects, so we can pass in blobs extracted from the package without ever writing them to temp files. The patching code is changed to read the patch from memory instead of a file. A bunch of compiler warnings (mostly about signed vs unsigned types) are fixed. Support for the IMGDIFF1 format is dropped. (We've been generating IMGDIFF2 packages for some time now.) Change-Id: I217563c500012750f27110db821928a06211323f
* relocate applypatch; add type system and new functions to edifyDoug Zongker2010-02-181-0/+900
- Move applypatch to this package (from build). - Add a rudimentary type system to edify: instead of just returning a char*, functions now return a Value*, which is a struct that can carry different types of value (currently just STRING and BLOB). Convert all functions to this new scheme. - Change the one-argument form of package_extract_file to return a Value of the new BLOB type. - Add read_file() to load a local file and return a blob, and sha1_check() to test a blob (or string) against a set of possible sha1s. read_file() uses the file-loading code from applypatch so it can read MTD partitions as well. This is the start of better integration between applypatch and the rest of edify. b/2361316 - VZW Issue PP628: Continuous reset to Droid logo: framework-res.apk update failed (CR LIBtt59130) Change-Id: Ibd038074749a4d515de1f115c498c6c589ee91e5
