2018-01-06dload: ensure callback is always initialized onceAndrew Gregory1-4/+5
Frontends rely on an initialization call for setup between downloads. Checking for intialization after checking for a completed download can skip initialization in cases where files are small enough to be downloaded all at once (FS#56408). Relying on previous download size can result in multiple initializations if there are multiple non-transfer events prior to the download starting (fS#56468). Introduce a new cb_initialized variable to the payload struct and use it to ensure that the callback is initialized exactly once prior to any actual events.

2016-12-05Parametrise the different ways in which the payload is resetMartin Kühne1-0/+10
In FS#43434, Downloads which fail and are restarted on a different server will resume and may display a negative download speed. The payload's progress in libalpm was not properly reset which ultimately caused terminal noise because the line width calculation assumes positive download speeds. This patch fixes the incomplete reset of the payload by mimicing what be_sync.c:alpm_db_update() does over in sync.c:download_single_file(). The new dload.c:_alpm_dload_payload_reset_for_retry() extends beyond the current behavior by updating initial_size and prevprogress for this case. This makes pacman reset the progress properly in the next invocation of the callback and display positive download speeds. Fixes FS#43434.

2016-10-22Add ALPM_ERR_OK to _alpm_errno_tIvy Foster1-1/+1
This allows functions which return an _alpm_errno_t to always return a genuine _alpm_errno_t for consistency, even in cases where there are no errors. Since ALPM_ERR_OK = 0, their callers can still simply check 'err = some_fn(); if (!err) { ... }'. Signed-off-by: Ivy Foster <ivy.foster@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2016-08-31Replace CURLOPT_PROGRESSFUNCTION with CURLOPT_XFERINFOFUNCTIONIvy Foster1-9/+9
Curl 7.32.0 added CURLOPT_XFERINFOFUNCTION, which deprecates CURLOPT_PROGRESSFUNCTION and means less casting doubles to size_ts for alpm. This change has no user-facing nor frontend-facing effects. Signed-off-by: Ivy Foster <ivy.foster@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2016-08-30Normalize alpm download callback's frontend cb argumentsIvy Foster1-6/+16
When curl calls alpm's dlcb, alpm calls the frontend's cb with the following (dlsize, totalsize) arguments: 0, -1: initialize 0, 0: no change since last call x {x>0, x<y}, y {y>0}: data downloaded, total size known x {x>0}, x: download finished If total size is not known, do not call frontend cb (no change to original behavior); alpm's callback shouldn't be called if there is a download error.

2014-10-02alpm: Fix wrong xferred/total sizes when resuming downloadsOlivier Brunel1-1/+3
When a package is already partially downloaded in the cache, its download size will only be of what's left to be downloaded. Since pkg->download_size is what's used when calculating the total download size for the totaldl callback, same thing apply. However, the download progress callback was including this initial size, which would thus lead to invalid values (and percentage) used in frontends. That is, the progress bar could e.g. go further than 100% In the case of pacman, there is a sanity check for different historical reason (44a57c89), so before the possible "overflow" was noticed, the total download size/progress reported was wrong. Once caught, the TotalDownload option was ignored and it would use individual file download values as fallback instead.

2013-09-18dload: avoid renaming files downloaded via sync operationsChristian Hesse1-17/+21
If the server redirects from ${repo}.db to ${repo}.db.tar.gz pacman gets this wrong: It saves to new filename and fails when accessing ${repo}.db. We need the remote filename only when downloading remote files with pacman's -U operation. This introduces a new field 'trust_remote_name' to payload. If set pacman downloads to the filename given by the server. The field trust_remote_name is set in alpm_fetch_pkgurl(). Fixes FS#36791 ([pacman] downloads to wrong filename with redirect).

2013-07-05do not check error from close(2)Dave Reisner1-1/+1
On operating systems we support, the behavior is always such that the kernel will do the right thing as far as invalidating the file descriptor, regardless of the eventual return value. Therefore, potentially looping and calling close multiple times is wrong. At best, we call close again on an invalid FD and throw a spurious EBADF error. At worst, we might close an FD which doesn't belong to us when a multi-threaded application opens its own file descriptor between iterations of the loop.

RFC 2616 doesn't forbid a 301 or 302 repsonse from having a body, and servers exist in the wild that show this behavior. In order to prevent pacman from showing a progress bar when we aren't actually downloading a package (and merely following one of these pain in the butt redirects), capture the server response code in the response header, rather than waiting to peel it off the handle after the download has finished.

2012-02-20Print error message when to-be-downloaded file cannot be createdNagy Gabor1-0/+4
It can happen that the to-be-downloaded file cannot be created in cachedir. For example, I am an -Sup user, and it is comfortable to set --cachedir to /mnt/pendrive, which is a FAT filesystem, so files like capseo-1:0.3-2-i686.pkg.tar.xz cannot be downloaded to there. Before this patch, pacman didn't give clear output about what happens when the download code could not create the necessary file. This can be confusing with -Su. An example output: *** $ sudo pacman -S capseo bochs --cachedir /c/TEMP resolving dependencies... looking for inter-conflicts... Targets (2): bochs-2.4.6-1 capseo-1:0.3-2 Total Download Size: 0.61 MiB Total Installed Size: 2.61 MiB Proceed with installation?
